Definitions
- This invention relates to the use of carbonwebs in manifolding separate work-sheets.
- the separate plies of carbon-web may be wound upon one or more spools placed upon the carriage of the typewriting machine.
- the objects of the invention are to improve the efilciency of the machine, to economize in cost of stationery, simplify the operation and increase the capacity, and to provide improved condensed record-devices, etc.
- the platen in a fan-fold typewriting machine is generally mounted upon a hinged frame, which swings the platen upwardly and. forwardly to an inverted position.
- a different kind of swing-frame is employed, and it is swimg upwardly and rearwardly from normal position. The platen therefore does not obstruct the manipulation of the carbons and work-sheets,
- the bed is provided with side guides for the sheets, and also with stops or gages against which the rear ends of the sheets are set.
- gages are made adjustable forward and back for a. distance of many inches, so as to accommodate different lengths of work-sheets, and also so as to provide for different depths of printed headings upon the sheets.
- the sheets by being set back against the gages, are brought to their printing positions, so that they do not d any further adjustment. It is only necessary to swing the platen homeupon the gathered sheets and carbons, and proceed at once to write the first line of typing without readjustment of the sheets upon the platen.
- a deflector Upon the front of the carriage is mounted a deflector to support and guide the front end of the pack of sheets while the descending platen is doubling the pack in the cradle. This deflector is then swung back to form a front paper-guide and presses the pack against the front of the platen.
- the sheets are held against disarrangement by means of a spring-clamp.
- the clamp is mounted in open condition upon the bed, and is automatically swung over and down upon the sheets, and holds them firmly so that hey will not become disarranged by the action of the platen, in thrusting down the pack into the throat which forms between the bed and the front deflector.
- the platen-swing-frame may be provided with as a latch to hold it down in working position, and this latch may be connected to cause said clamp to open when the down-swinging platen presses the sheets against the bottom feed-rolls.
- this latch may be connected to cause said clamp to open when the down-swinging platen presses the sheets against the bottom feed-rolls.
- the platen-swing-frame is pivoted tothe caseshift frame of the machine.
- This case-shift frame is mounted upon the main carriage, to shift up and down for capital letters. From the ends of the case-shift frame, extend rearwardly and upwardly a pair of arms, and the platen-swing frame is hinged in said arms.
- the platen when elevated is above the range of vision, so that the operator can see beneath it, and can see the carbon-spools at the back of of the machine, and can conveniently reach beneath the platen for manipulating the sheets and parts.
- the adding mechanism in an Underwood bookkeeping machine extends up to an elevation above the typewriter platen.
- One of the features of the present improvements relates to overcoming the resulting difficulty, and to conveniently assembling the sheets and carbons and conducting them down in front of the adding mechanism and in rear of the'platen and under the latter.
- the platen-swing-frame is constructed to clear the dogs that form a part of the adding machine, and are usually adjustable along the rear side of the carriage.
- the work-sheets lie fiat upon the bed above the dogs. form, to afford a view of the racks and dogs of the adding mechanism.
- the gages for the rear ends of the sheets are so placed that when the platen is pressed down and forms the pack of sheets into a loop, the
- the sheet-gages being adjustable forwardly and backwardly, permit nice pre-set adjustment of the sheets relatively to the printing line on the platen, so that the first typing will fall upon the desired line which is printed upon the form.
- the spools are mounted upon the main carriage of the typewriter and need not travel forwardly, but may stay in one place.
- the carbons may be rewound upon the spools, after the completion of the typing of each page.
- the rewinding may be done by means of a take-up spring.
- Each spool-core may be connected by a light spring to its main shaft, so as to afford a yielding action and guard against tearing of the carbon.
- a condensed record-sheet There may be carried around the platen a condensed record-sheet. Ihis sheet may permanently stay in place upon the platen, to be swun up therewith away from the interleaving bed. When the platen is down, the record-sheet will feed around the platen together with the pack of work-sheets and carbon-leaves. When the platen is up, the record-sheet is retained thereon by means of special rolls mounted upon the platen-swing-frame and running upon the platen at its end portions only. Said rolls engage the side margins of the condensed record-sheet, whose width exceeds that of the main worksheets. As is common in fan-fold machines, especially those which embody the Underwood bookkeeping mechanism, the line-space wheel is connected by means of a gear-train to the platen.
- Said train consists of a gear which is fixed to the line-space wheel, and a pinion on the platen-frame which meshes with said gear, and also a gear upon the platen which meshes with said pinion, whereby the platen is held steady by a spring-detent which works in the usual line-space wheel.
- a spring-detent which works in the usual line-space wheel.
- the present invention provides The bed is made of skeleton a loading'bed which is mounted upon the typewriter-carriage. This figure illustrates the forward ends of carbon-leaves being held ready to drop upon a work-sheet when the latter has been deposited upon another carbon-leaf lying in the bed or box.
- Figure 3 shows the gathered sheets and carhon-leaves as being clamped against the gathering bed, and shows the platen being dropped to printing position.
- Figure 4 shows the next step to Figure 3.
- the pack of sheets is shown as being folded and tucked down by the descending platen, while the sheets are held firmly clamped to the bed whereby the sheets are being mechanically brought to the correct printing position seen at Figure 1.
- Figure 5 shows the typing of a page as having been completed; the pack of work-sheets and carbons having been fed around the bottom and front of the platen and upwardly towards the rear of the machine.
- Figurev 6 shows the platen as having been swung up, thereby releasing the work-sheets; and the latter are now pulled or stripped forwardly clear of the carbons, which may be automatically rewound upon their respective spools.
- a condensed record-sheet is shown as retaining its position upon the platen, being. swung up therewith.
- Figure 7 is a plan, with some parts in section, showing the present improvements, with the parts in normal printing positions.
- Type-bars I0 strike against the front of a platen H revolubly mounted upon an axle l2 in a frame, the latter being supported upon a carriage l3 sliding upon rear rail I4 and front track 15. bookkeeping machine, is spring-propelled and controlled by a letter-feeding mechanism.
- Releasable feed-rolls I5 It: run upon the bottom of the platen, which overlies the usual paperguiding apron IS.
- the usual front wing-scale is seen at I5
- Thenovel manner of gathering work-sheets l6 and carbon-leaves I1 is illustrated at Figure 2, in which the platen is shown as elevated well above its dotted-dine printing position, so that. the work-sheets and carbons may be manipulated in the ample space which is afforded below the platen and above the carriage.
- the platen swing-frame or bail includes arms l8, hinged at l8, and united by a. cross-bar 20.
- the arms l9 have journal bearings for the main axle I! of the platen.
- Said swing-frame is hinged upon a pair of brackets 2
- the carriage as usual in an Underwood which may be eitherfixed to the carriage l3 or frame to swing up and down for printing upper and lower case types.
- extend upwardly and rear wardly and bend backwardly over the usual parts of the adding mechanism in said machine, seen at Figure 1, and including denomination-jacks 24 and operating dogs 25 therefor; these adding parts usually rising to a level which is substantially above the normal printing position of the platen, Figure 1.
- the first work-sheet l6 may be laid upon a gathering bed 26, which occupies a position between the platen-swing-frame arms I 9 and extendsrearwardly from the intake side of the platen.
- the bed has a pair of separated headgages 21, against which the rear ends of the worksheets are set. These gages are adjustable forwardly and rearwardly.
- the bed may have openings 25 for access to dogs 25.
- the work-sheets fit loosely between side guides 28, so that it is only necessary to drop a worksheet upon the bed between the side guides, and set it back to the head-gages 21; whereupon a carbon-leaf I1 may be swung down upon the same. 4
- a second work-sheet l 6 may be deposited upon said carbon-leaf. Then the next carbon may be swung down upon said second work-sheet, and so on, for as many work-sheets and carbons as may be' desired.
- the gathering box may be made in sections adjustable for width, and fastened by screws 28 upon cross-bar 28 which forms part of a rear extension of the main carriage-frame; said extension including rear carriage-arms 28 connected by said cross-bar 28".
- These carbon-leaves may be pulled off from one or more spools 29, mounted preferably one above another in rear of hinge I8 and of the gathering bed or box.
- the carbons are somewhat narrower than the work-sheets, so that the carbons may swing down and travel between the opposite headgages 21.
- the gages are sufficiently broad to afford satisfactory engagement therewith by the rear corners of the work-sheet;
- the platen is so high as seen at Figure 2 as to facilitate holding up the front end of the pack of carbon-leaves in the fingers and dropping them one after another as required.
- the large opening below the elevated platen and above the carriage has also the advantage of permitting the work-sheets to be introduced into the gathering box from the front and thrust rearwardly against the head-gages 21.
- the forward portion of the pack of sheets may rest upon a table-leaf 30, which may be hinged at 3
- This leaf thus forms a forward extension of the gathering bed, and only a short end of the gathered sheets needs to project forwardly from the extended leaf, so that for some kinds of work said forward end may be self-supporting.
- the main or rear portion of the interleaving; bed does not project into the path of the descending platen, but the leaf which is pivoted to the front of said main portion gives the latter a sufficient extension to afford ample support for the pack; and it is conveniently swung down out of the way by the platen, all of the sheets being pressed and held between the platen and the spring-pressed leaf, so as to insure a smooth bending of the pack over the corner between the main work-bed and the swing-down leaf, as the platen tucks the pack down into the throat.
- the sheets may be brought automatically to correct typing positions with relation to the front scale l and are ready for typing the first line thereon; it only being necessary to adjust the head-gages 21 forwardly or rearwardly to secure the desired printing position of the sheets, which therefore do not need to be adjusted after the platen has dropped upon them, thus saving an operation.
- the carbons are quickly interleaved with the work-sheets, and mechanically brought to correct printing positions, and it will be evident that a substantial advantage is gained by this invention, as compared with web-manifolding machines of standard manufacture, because of avoidance of the necessity of printing long workweb embodies several plies, one ply for each kind of repeated form. All of the piles are printed at the same time, requiring the use of a wide original web.
- the type-forms accordingly have to be mounted upon a printing cylinder of great length.
- the cylinder has to be made of great diameter, in order to prove stiff at the printing operation.
- Each type-form therefore has to be repeated several times around its printing cylinder, whose circumference is very large.
- a sheet-clamp 32 may be swung down to hold the sheets firmly upon the table, as at Figures 3, 4.
- This clamp may be swung down automatically by a spring 33, the movement being controlled by a lift-arm 35 that is provided upon one of the arms 36 upon which the clamp-bar 32 is mounted.
- Said clamp-bar and arms 36 form a bail which is pivoted at 34 to the brackets 2
- the lift-arm 35 which is pressed by clamping spring 33, is restrained at Figure 2 by a pin 31 projecting from arm 19 of the platen-swingframe.
- the spring 33 carries down the clamp 32 as permitted by the pin 31, and finally clamps the gathered sheets upon the front end of the gathering bed as at Figure 3.
- the spring 33 continues to clamp the sheets upon the bed during the remainder of the downward swing of the platen-frame from the fullline stage at Figure 3 to the dotted-line printing position.
- a set of rolls 38 mounted upon a rod or shaft 40, the latter fixed to arms 38 which are hinged at 48 upon brackets 39 fixed upon the platen-frame ends 23.
- the rolls 38 are adapted to run upon the side margins of the work-sheets, and may be adjusted along the rod 40 in a known manner.
- the rolls 38, rod 40 and guides 42 form a deflector which occupies an open position extending forwardly and upwardly from the hinge 40.
- This deflector may form a support for the forward ends of the sheets when they are being gathered, and later as they are being pressed down by the descending platen. It will be seen that the platen tucks the pack down into a throat, of which the rear member is the spring leaf 30, and the front member includes said deflector 38, 40, 42.
- a projection 45 thereon strikes an operating arm 46 on the hinge-pintle 40, and swings said arm with its deflector-members 38, 40 and 42, to a position to press the work-pack back against the front of the platen, the parts being held normally .n this position by a double-acting spring 41, Figure 1.
- This spring is also adapted to hold the deflector-parts in the open-throat positions shown at Figure 2, to which open position the deflector is rocked by means of a projection 48 on said arm of the up-swinging platen-frame.
- the deflector remains in its open position until the platen has nearly finished its descent, but is continuing to press the sheets downwardly as well as rearwardly against the spring leaf.
- the rolls 38 and front paper-guide 42 are moving back to their paper-holding positions at Figure 4, just before the descending platen reaches its printing position; and the pack of paper is brought tautly and firmly against the platen at the printing line.
- a stud 49 Upon each of the swinging side arms i3 is provided a stud 49, which swings down against a cam-edge 50 that is provided upon a latch p'voted at 52 to the platen-frame and snapped forwardly by a spring 53.
- This latch is similar to that which is usual in the Underwood fan-fold typewriting machine.
- the pin 49 presses back the cam 50, which forms the nose of a hook; and finally the hook-portion 54 of the latch catches over the pin 43, to hold down the platenswing-frame firmly in printing position, Figure 1.
- also forms a means for releasing the pack-clamp 32 from its effective position at Figure 4; the forward edge of the nose of the hook 54 now engaging a pin 55 that is provided upon the forward end of a link 56, the link being pivoted to an arm 51 upon the clamp-frame 32, to raise the clamp against the tension of its spring 33.
- the normal position of the clamp is just a little above the work, as seen at Figure 1.
- the spring 33 tends always to close the clamp 32 upon the sheets; but the clamp is held up while the platen is fully elevated, as at Figure 6.
- the pin 31 swings down and is followed by the arm 35, due to the tension of the spring 33; and when the platen has made about one-half of its descent,
- the clamp 32 is forced by the spring 33 to press the work upon the bed 26, as at Figure 3.
- the spring maintains the clamp closed during the lowering of the platen to the full-line position of Figure 4, and also until the platen reaches the Figure 4 dotted-line printing position, thereby thrusting the sheets against the feed-rolls l5", l5".
- latches over the pin 49, and simultaneously carries forward the pin 55 and its link 56, releasing the clamp 32 from the sheets, as it is no longer necessary to clamp the latter upon the bed.
- the platen-swing-frame may be provided with a counterbalancing spring 58, Figures 1 and 7.
- the platen-swing-frame when tilted up, rests against a stop 58 provided upon the end of the bracket 2
- the drop leaf 38 is depressed against a spring 60, the latter serving to return the leaf to working position and to hold it elevated, at Figure 2; this leaf having side-edge gages 6
- Other side-guides Gl may be provided for the forward ends of the sheets, and adjustably clamped at 6i upon the front bar of the main carriage l3. These side-guides til are especially useful with the shorter worksheets, which do not lie far back in the aligning bed 26.
- the upstanding forward ends of the work-sheets l6 are retained at the delivery side of the platen by means of the fingers 42, the sheets being confined between said fingers and a paper-table 62 which extends along the top of the platen.
- the platen is line-spaced by a handle 63, Figure 7, and the sheets are fed upwardly over the platen, and are shown at Figure 5 at the completion of the typing of the page.
- the swing-frame l3 may now be raised from printing position, and its pin 48 may lift the arm 46 to swing forwardly the front paper-fingers 42, together with the front rolls 38 and their supporting arms 39, these parts turning as a unit upon the hinge 40 and releasing the work-pack and pressing the spring 41 past dead center; said spring thereupon completing the swinging of the aforesaid parts 42, etc., to the open position at Figure 2, for deflecting the next inserted pack.
- the typed sheets l6, no longer confined by the fingers 42, may be brought forwardly and down to 'a flat condition, and stripped or pulled out from the carbon-leaves H, as will be understood from the diagram Figure 6.
- the carbon-leaves I! may be retracted by means of light coiled take-up springs 64', which rewind the carbons upon the cores 29.
- Each spring is very lightly tensioned, so that the .carbon may readily yield to a pull thereon, thus avoiding danger of injury.
- the tension may be 'just suflicient to rewind the carbons to the extent seen at Figure 2, the extent of the rewinding corresponding with the length of the typed page.
- the spool may be detachably fitted upon a square shaft 66, which is removably mounted at one end in the carriage-bracket 28.
- the shaft may be releasably secured by a latch 61, the other end of the spool-shaft being fitted in a loose hub 68 adjoining the barrel69 which carries take-up spring 64.
- the hub 68 can be rotated relatively to the spring-barrel; but the extent of rotation is limited by means of a follower 18, which has finally the follower reaches the end of the groove and is arrested thereby, and this terminates the free play of the carbon-leaf relatively to the stationary spring-barrel 69.
- Said barrel may itself be forcibly rotated, by giving a somewhat stronger pull upon forward end trimmed ofi from time to time; while at any time the take-up spring 64 will rewind the carbon upon the spools to the extentabove noted.
- the barrel 69 may also be revolved at will by means of a handle 15 extending forwardly and returned by a spring 16.
- This handle is connected'at its rear end to an arm 11 carrying a pawl 18, to mesh with a ratchet 19 fixed to the main barrel-hub 88, as by means of a set-screw 8
- a knob 83 is-fixed to the main barrel-hub 88, for winding ⁇ or unwinding the carbon if desired.
- Said arm 11 may be connected by a link 84 to a similar arm 85, having a ratchet 86 to operate a ratchet-wheel -upon the lower spool. To-and-fro movement of the handle 15 will cause intermittent unwinding of both spools against the opposition of the friction devices.
- the front ends of the work-sheets I6 may be grasped to strip them from the carbons. If the carbons should stick to the work-sheets, so that the latter would tend to pull the carbons still further forwardly, such pull would be resisted by the friction washers 13 and springs 14, so that the work-sheets would release thecarbons and not unwind the spools farther. Then the opera tor may grasp the forward ends of the carbons and raise them to the position at Figure 2 for gathering a fresh pack asabove explained.
- the condensed record-sheet 81 is held permanently wrapped upon the elevatable platen-by front and rear feed-rolls 88, 89. The rolls and the sheet rise with the platen, as at Figure 3.
- the record-sheet 81 may be manifolded by the uppermost carbon-leaf I1.' But, if desired, amain work-sheet I6 may be laid upon said top carbon-leaf, and there may be provided for the record sheet or sheets 81 a special carbon sheet or sheets, to enwrap the record-sheets and to be permanently held interleaved'therewith by the rolls 88, 89. These rolls run upon the side -margins of the condensed record-sheets, as seen in Figure '1; the condensed record-sheet being wider than the main work-sheet I6.
- the front rolls 88 may be adjusted along slots 98 in the top paper-shelf 62.
- the rolls 89 may be carried upon spring arms 9
- the slots 98 extend far enough out from the platen to permit the rolls 88 to be withdrawn from the condensed record sheets.
- the line-space wheel 95 is usually connected to a gear 96, which is companion to a coaxial gear 91. Both gears are shown in mesh with a common pinion 98, so that the platen is positively entrained with said line-space wheel 95. Similar gears and pinions are provided at the opposite end of the platen, as indicated at 99, I88, I8I.
- the platen-gears 91, 99 swing up away from the pinions 98, I8I, but means is provided to keep arms I9 of the platen-swing-frame, so that it may swing down against the platen. It is normally held up by an arm I84, which is rigid with the brake, and which normally rests upon a pin I that projects from the end of the platen-shift-frame 23, which does not rise when the platen is elevated.
- a spring I86 throws the brake I82 down upon the platen as soon as permitted by, the pin I85.
- the platen cannot rotate, but, after being elevated and dropped, presents the'same line of the condensed recordsheet to the types as before it is elevated.
- the line-spacing "of the condensed recordsheets is effected by the handle 63, together with the main work-sheets; and since said handle 63 is employed for returning the carriage to begin a new line, it happens that the condensed record-sheets are line-spaced, and are ready for co-operation with the next inserted work-sheets.
- a front-strike typewriting machine the combination with a carriage, of a platen, paperfeed devices coacting with the under side of the platen to pass a work-sheet under and up around the front of the platen, an intercalating bed supported upon said carriage and extending rearwardly from the platen and paper-feed devices, for intercalating work-sheets with carbon webs, a frame for supporting the platen upon the carriage for displacement upwardly from printingposition, to afford clearance for the intercalating operation, said bed having at the side a gage for the rear ends of the work-sheets, to position the latter so that their forward portions project forwardly to overlie said exposed paper-feed devices, and a carbon-web supply supported in the rear of said gage to permit forward movement of the carbons with the work-sheets over said bed, the carbons passing alongside said gage, said-paperfeed devices becoming effective, when the platen has been returned to printing-position, to cooperate with the platen to grip the sheets preparatory to typing the page.

48 Claims. -(Cl. 191-131) A This invention relates to the use of carbonwebs in manifolding separate work-sheets. The separate plies of carbon-web may be wound upon one or more spools placed upon the carriage of the typewriting machine.
The objects of the invention are to improve the efilciency of the machine, to economize in cost of stationery, simplify the operation and increase the capacity, and to provide improved condensed record-devices, etc.
. An Underwood bookkeeping machine is illustrated, but the invention may be applied to other machines, either'with or without adding mechanism.
v The platen in a fan-fold typewriting machine is generally mounted upon a hinged frame, which swings the platen upwardly and. forwardly to an inverted position. In the present invention a different kind of swing-frame is employed, and it is swimg upwardly and rearwardly from normal position. The platen therefore does not obstruct the manipulation of the carbons and work-sheets,
nor does the operator have to reach above and their forward ends are held up by the operator while he thrusts the sheets one by one rearwardly under the elevated platen and drops them upon the assembling bed.
The bed is provided with side guides for the sheets, and also with stops or gages against which the rear ends of the sheets are set.
These gages are clear of the carbon-webs For this purpose the bed is made wider than the carbons; and upon the bed is fixed at each side one of the gages. 'Ihe carbons may thus lie or travel between said gages, but the latter have sufficient dimensions so that they may be engaged by the rear corners of the work-sheets, to align the same.
These gages are made adjustable forward and back for a. distance of many inches, so as to accommodate different lengths of work-sheets, and also so as to provide for different depths of printed headings upon the sheets. The sheets, by being set back against the gages, are brought to their printing positions, so that they do not d any further adjustment. It is only necessary to swing the platen homeupon the gathered sheets and carbons, and proceed at once to write the first line of typing without readjustment of the sheets upon the platen.
'Ihe platen, as it is swung down, encounters the sheets which lie upon the bed, and folds or presses down their forward portions. From the 5 front of the bed may extend a hinged leaf which is pressed down by the descending platen together with the pack of sheets and carbons lying thereon; the assemblage of sheets and carbons bending down around the corner or front portion of the 10 bed, where the leafis hinged to the main bed. The platen as it descends doubles the pack downwardly, and its un er side becomes enveloped in said pack, and pre es the pack down against the usual feed-rolls, which run upon the underside of .the platen. The pack forms a loop which is thus pressed into the cradle which is formed by the usual bottom sheet-metal paper-guiding apron.
Upon the front of the carriage is mounted a deflector to support and guide the front end of the pack of sheets while the descending platen is doubling the pack in the cradle. This deflector is then swung back to form a front paper-guide and presses the pack against the front of the platen.
During this pack-doubling operation, the sheets are held against disarrangement by means of a spring-clamp. The clamp is mounted in open condition upon the bed, and is automatically swung over and down upon the sheets, and holds them firmly so that hey will not become disarranged by the action of the platen, in thrusting down the pack into the throat which forms between the bed and the front deflector.
The platen-swing-frame may be provided with as a latch to hold it down in working position, and this latch may be connected to cause said clamp to open when the down-swinging platen presses the sheets against the bottom feed-rolls. Thus the pack of sheet is always firmly held, and it may now be readily advanced by rotating the platen. The sheet-clamp will remain open until the assembling of the next pack of sheets is completed.
The platen-swing-frame is pivoted tothe caseshift frame of the machine. This case-shift frame is mounted upon the main carriage, to shift up and down for capital letters. From the ends of the case-shift frame, extend rearwardly and upwardly a pair of arms, and the platen-swing frame is hinged in said arms.
The platen when elevated is above the range of vision, so that the operator can see beneath it, and can see the carbon-spools at the back of of the machine, and can conveniently reach beneath the platen for manipulating the sheets and parts.
The adding mechanism in an Underwood bookkeeping machine extends up to an elevation above the typewriter platen. One of the features of the present improvements relates to overcoming the resulting difficulty, and to conveniently assembling the sheets and carbons and conducting them down in front of the adding mechanism and in rear of the'platen and under the latter.
The platen-swing-frame is constructed to clear the dogs that form a part of the adding machine, and are usually adjustable along the rear side of the carriage. The work-sheets lie fiat upon the bed above the dogs. form, to afford a view of the racks and dogs of the adding mechanism.
The gages for the rear ends of the sheets are so placed that when the platen is pressed down and forms the pack of sheets into a loop, the
front ends of the sheets will be at-the printing point in the exact position required, so that typing may proceed as soon as the platen is swung down. The sheet-gages being adjustable forwardly and backwardly, permit nice pre-set adjustment of the sheets relatively to the printing line on the platen, so that the first typing will fall upon the desired line which is printed upon the form.
The spools are mounted upon the main carriage of the typewriter and need not travel forwardly, but may stay in one place. The carbons may be rewound upon the spools, after the completion of the typing of each page. The rewinding may be done by means of a take-up spring. Each spool-core may be connected by a light spring to its main shaft, so as to afford a yielding action and guard against tearing of the carbon. When the forward or fly-leaf ends of the carbon-webs are worn out, fresh portions of the carbon-webs may be pulled forwardly from the spools, and the worn portions are then trimmed ofi.
There may be carried around the platen a condensed record-sheet. Ihis sheet may permanently stay in place upon the platen, to be swun up therewith away from the interleaving bed. When the platen is down, the record-sheet will feed around the platen together with the pack of work-sheets and carbon-leaves. When the platen is up, the record-sheet is retained thereon by means of special rolls mounted upon the platen-swing-frame and running upon the platen at its end portions only. Said rolls engage the side margins of the condensed record-sheet, whose width exceeds that of the main worksheets. As is common in fan-fold machines, especially those which embody the Underwood bookkeeping mechanism, the line-space wheel is connected by means of a gear-train to the platen. Said train consists of a gear which is fixed to the line-space wheel, and a pinion on the platen-frame which meshes with said gear, and also a gear upon the platen which meshes with said pinion, whereby the platen is held steady by a spring-detent which works in the usual line-space wheel. In the present illustra tion, when the platen-frame is swung upwardly the platen-gear is swung out of mesh with said line-space gear. The present invention provides The bed is made of skeleton a loading'bed which is mounted upon the typewriter-carriage. This figure illustrates the forward ends of carbon-leaves being held ready to drop upon a work-sheet when the latter has been deposited upon another carbon-leaf lying in the bed or box.
Figure 3 shows the gathered sheets and carhon-leaves as being clamped against the gathering bed, and shows the platen being dropped to printing position.
Figure 4 shows the next step to Figure 3. At Figure 4, the pack of sheets is shown as being folded and tucked down by the descending platen, while the sheets are held firmly clamped to the bed whereby the sheets are being mechanically brought to the correct printing position seen at Figure 1. a
Figure 5 shows the typing of a page as having been completed; the pack of work-sheets and carbons having been fed around the bottom and front of the platen and upwardly towards the rear of the machine.
Figurev 6 shows the platen as having been swung up, thereby releasing the work-sheets; and the latter are now pulled or stripped forwardly clear of the carbons, which may be automatically rewound upon their respective spools. A condensed record-sheet is shown as retaining its position upon the platen, being. swung up therewith.
Figure 7 is a plan, with some parts in section, showing the present improvements, with the parts in normal printing positions.
Type-bars I0 strike against the front of a platen H revolubly mounted upon an axle l2 in a frame, the latter being supported upon a carriage l3 sliding upon rear rail I4 and front track 15. bookkeeping machine, is spring-propelled and controlled by a letter-feeding mechanism. Releasable feed-rolls I5 It: run upon the bottom of the platen, which overlies the usual paperguiding apron IS. The usual front wing-scale is seen at I5 Thenovel manner of gathering work-sheets l6 and carbon-leaves I1 is illustrated at Figure 2, in which the platen is shown as elevated well above its dotted-dine printing position, so that. the work-sheets and carbons may be manipulated in the ample space which is afforded below the platen and above the carriage.
The platen swing-frame or bail includes arms l8, hinged at l8, and united by a. cross-bar 20. The arms l9 have journal bearings for the main axle I! of the platen. Said swing-frame is hinged upon a pair of brackets 2| secured by screws 22 to the ends 23 of the platen-frame,
The carriage, as usual in an Underwood which may be eitherfixed to the carriage l3 or frame to swing up and down for printing upper and lower case types.
Said brackets 2| extend upwardly and rear wardly and bend backwardly over the usual parts of the adding mechanism in said machine, seen at Figure 1, and including denomination-jacks 24 and operating dogs 25 therefor; these adding parts usually rising to a level which is substantially above the normal printing position of the platen, Figure 1.
When the platen is elevated to the full-line Figure 2 position, the first work-sheet l6 may be laid upon a gathering bed 26, which occupies a position between the platen-swing-frame arms I 9 and extendsrearwardly from the intake side of the platen. The bed has a pair of separated headgages 21, against which the rear ends of the worksheets are set. These gages are adjustable forwardly and rearwardly. The bed may have openings 25 for access to dogs 25.
The work-sheets fit loosely between side guides 28, so that it is only necessary to drop a worksheet upon the bed between the side guides, and set it back to the head-gages 21; whereupon a carbon-leaf I1 may be swung down upon the same. 4
A second work-sheet l 6 may be deposited upon said carbon-leaf. Then the next carbon may be swung down upon said second work-sheet, and so on, for as many work-sheets and carbons as may be' desired. The gathering box may be made in sections adjustable for width, and fastened by screws 28 upon cross-bar 28 which forms part of a rear extension of the main carriage-frame; said extension including rear carriage-arms 28 connected by said cross-bar 28".
These carbon-leaves may be pulled off from one or more spools 29, mounted preferably one above another in rear of hinge I8 and of the gathering bed or box. The carbons are somewhat narrower than the work-sheets, so that the carbons may swing down and travel between the opposite headgages 21. The gages, however, are sufficiently broad to afford satisfactory engagement therewith by the rear corners of the work-sheet; and
.they are adjustable forwardly and backwardly for different lengths of sheets and for different printin positions of the sheets, being secured by screws 21.
The platen is so high as seen at Figure 2 as to facilitate holding up the front end of the pack of carbon-leaves in the fingers and dropping them one after another as required. The large opening below the elevated platen and above the carriage has also the advantage of permitting the work-sheets to be introduced into the gathering box from the front and thrust rearwardly against the head-gages 21.
The forward portion of the pack of sheets may rest upon a table-leaf 30, which may be hinged at 3| to the front end of the bed 26. This leaf thus forms a forward extension of the gathering bed, and only a short end of the gathered sheets needs to project forwardly from the extended leaf, so that for some kinds of work said forward end may be self-supporting.
It will be seen at Figure 2 that the platen swings so far upwardly and rearwardly off from the carriage, as to leave an ample opening under the platen into which the work-sheets may be conveniently thrust rearwardly into the gathering box -and against the head-gages, while the carbon-leaves may be pulled forwardly from the spools under the platen and conveniently held up by means of their forward ends and conveniently oearcu nun dropped one by one upon the work-sheets as they are laid in place.
The main or rear portion of the interleaving; bed does not project into the path of the descending platen, but the leaf which is pivoted to the front of said main portion gives the latter a sufficient extension to afford ample support for the pack; and it is conveniently swung down out of the way by the platen, all of the sheets being pressed and held between the platen and the spring-pressed leaf, so as to insure a smooth bending of the pack over the corner between the main work-bed and the swing-down leaf, as the platen tucks the pack down into the throat.
In this way, the sheets may be brought automatically to correct typing positions with relation to the front scale l and are ready for typing the first line thereon; it only being necessary to adjust the head-gages 21 forwardly or rearwardly to secure the desired printing position of the sheets, which therefore do not need to be adjusted after the platen has dropped upon them, thus saving an operation.
The carbons are quickly interleaved with the work-sheets, and mechanically brought to correct printing positions, and it will be evident that a substantial advantage is gained by this invention, as compared with web-manifolding machines of standard manufacture, because of avoidance of the necessity of printing long workweb embodies several plies, one ply for each kind of repeated form. All of the piles are printed at the same time, requiring the use of a wide original web. The type-forms accordingly have to be mounted upon a printing cylinder of great length. The cylinder has to be made of great diameter, in order to prove stiff at the printing operation. Each type-form therefore has to be repeated several times around its printing cylinder, whose circumference is very large. Moreover, a large quantity of forms has to be printed, in order to keep down the average cost of a printed form. The expense of printing an initial quantity of webs, therefore, is so great as often to defeat the sale of a fan-fold typewriter. The cost of the first lot of stationery may mount to many times the cost of the fan-fold typewriter itself. But, by reason of the present invention, the use of work-webs is avoided. The sheets may be printed upon an ordinary small printing press, and the form needs to be set up only once, as it may be altered before printing each different kind of form. The cost of stationery therefore being negligible, conduces to ready introduction of manifolding typewriters. The speed of operation of the invention is high, inasmuch as it-is not necessary to load a set of carbon-sheets at intervals, the sheets are brought quickly to printing position, and other time savings are also effected, as well as economy of carbon-paper.
' webs for use upon standard machines. Each such After the work-sheets and carbons have been gathered, and before the pack has been tucked down, a sheet-clamp 32 may be swung down to hold the sheets firmly upon the table, as at Figures 3, 4. This clamp may be swung down automatically by a spring 33, the movement being controlled by a lift-arm 35 that is provided upon one of the arms 36 upon which the clamp-bar 32 is mounted. Said clamp-bar and arms 36 form a bail which is pivoted at 34 to the brackets 2|.
The lift-arm 35, which is pressed by clamping spring 33, is restrained at Figure 2 by a pin 31 projecting from arm 19 of the platen-swingframe. As said swing-frame is swung downwardly, the spring 33 carries down the clamp 32 as permitted by the pin 31, and finally clamps the gathered sheets upon the front end of the gathering bed as at Figure 3.
The spring 33 continues to clamp the sheets upon the bed during the remainder of the downward swing of the platen-frame from the fullline stage at Figure 3 to the dotted-line printing position.
During this latter portion of the descent of the platen, it strikes the pack of sheets where they rest upon the spring leaf 38, and presses down the pack, and the leaf. The pack is doubled down over the front comer or end of the bed, and the leaf is swung downwardly and rearwardly to the position at Figure 4. The pack of sheets is thus formed into a loop which envelops the under side of the platen, with the front end of the pack extending upwardly and forwardly, Figure 4.
Upon the front of the platen run a set of rolls 38 mounted upon a rod or shaft 40, the latter fixed to arms 38 which are hinged at 48 upon brackets 39 fixed upon the platen-frame ends 23. The rolls 38 are adapted to run upon the side margins of the work-sheets, and may be adjusted along the rod 40 in a known manner.
There are also adjustable along the rod 40 splined work-retaining fingers 42 which extend up to hold back the middle portions of the workpack, so that the whole pack may be held smoothly against the platen at the printing line.
While the platen is elevated, the rolls 38, rod 40 and guides 42 form a deflector which occupies an open position extending forwardly and upwardly from the hinge 40. This deflector may form a support for the forward ends of the sheets when they are being gathered, and later as they are being pressed down by the descending platen. It will be seen that the platen tucks the pack down into a throat, of which the rear member is the spring leaf 30, and the front member includes said deflector 38, 40, 42.
As the platen-frame l8 swings down, a projection 45 thereon strikes an operating arm 46 on the hinge-pintle 40, and swings said arm with its deflector-members 38, 40 and 42, to a position to press the work-pack back against the front of the platen, the parts being held normally .n this position by a double-acting spring 41, Figure 1. This spring is also adapted to hold the deflector-parts in the open-throat positions shown at Figure 2, to which open position the deflector is rocked by means of a projection 48 on said arm of the up-swinging platen-frame.
The deflector remains in its open position until the platen has nearly finished its descent, but is continuing to press the sheets downwardly as well as rearwardly against the spring leaf. The rolls 38 and front paper-guide 42 are moving back to their paper-holding positions at Figure 4, just before the descending platen reaches its printing position; and the pack of paper is brought tautly and firmly against the platen at the printing line.
Upon each of the swinging side arms i3 is provided a stud 49, which swings down against a cam-edge 50 that is provided upon a latch p'voted at 52 to the platen-frame and snapped forwardly by a spring 53. This latch is similar to that which is usual in the Underwood fan-fold typewriting machine. The pin 49 presses back the cam 50, which forms the nose of a hook; and finally the hook-portion 54 of the latch catches over the pin 43, to hold down the platenswing-frame firmly in printing position, Figure 1. Said latch 5| also forms a means for releasing the pack-clamp 32 from its effective position at Figure 4; the forward edge of the nose of the hook 54 now engaging a pin 55 that is provided upon the forward end of a link 56, the link being pivoted to an arm 51 upon the clamp-frame 32, to raise the clamp against the tension of its spring 33. The normal position of the clamp is just a little above the work, as seen at Figure 1.
The spring 33 tends always to close the clamp 32 upon the sheets; but the clamp is held up while the platen is fully elevated, as at Figure 6. During the descent of the platen, the pin 31 swings down and is followed by the arm 35, due to the tension of the spring 33; and when the platen has made about one-half of its descent,
the clamp 32 is forced by the spring 33 to press the work upon the bed 26, as at Figure 3. The spring maintains the clamp closed during the lowering of the platen to the full-line position of Figure 4, and also until the platen reaches the Figure 4 dotted-line printing position, thereby thrusting the sheets against the feed-rolls l5", l5". At this time the hook 5| latches over the pin 49, and simultaneously carries forward the pin 55 and its link 56, releasing the clamp 32 from the sheets, as it is no longer necessary to clamp the latter upon the bed.
The platen-swing-frame may be provided with a counterbalancing spring 58, Figures 1 and 7. The platen-swing-frame when tilted up, rests against a stop 58 provided upon the end of the bracket 2|.
The drop leaf 38 is depressed against a spring 60, the latter serving to return the leaf to working position and to hold it elevated, at Figure 2; this leaf having side-edge gages 6| which form continuations of the gages 28 upon the main body of the bed or table. Other side-guides Gl may be provided for the forward ends of the sheets, and adjustably clamped at 6i upon the front bar of the main carriage l3. These side-guides til are especially useful with the shorter worksheets, which do not lie far back in the aligning bed 26.
At the beginning of the typing of the page, the upstanding forward ends of the work-sheets l6 are retained at the delivery side of the platen by means of the fingers 42, the sheets being confined between said fingers and a paper-table 62 which extends along the top of the platen. The platen is line-spaced by a handle 63, Figure 7, and the sheets are fed upwardly over the platen, and are shown at Figure 5 at the completion of the typing of the page.
The swing-frame l3 may now be raised from printing position, and its pin 48 may lift the arm 46 to swing forwardly the front paper-fingers 42, together with the front rolls 38 and their supporting arms 39, these parts turning as a unit upon the hinge 40 and releasing the work-pack and pressing the spring 41 past dead center; said spring thereupon completing the swinging of the aforesaid parts 42, etc., to the open position at Figure 2, for deflecting the next inserted pack. The typed sheets l6, no longer confined by the fingers 42, may be brought forwardly and down to 'a flat condition, and stripped or pulled out from the carbon-leaves H, as will be understood from the diagram Figure 6.
The carbon-leaves I! may be retracted by means of light coiled take-up springs 64', which rewind the carbons upon the cores 29. Each spring is very lightly tensioned, so that the .carbon may readily yield to a pull thereon, thus avoiding danger of injury. The tension may be 'just suflicient to rewind the carbons to the extent seen at Figure 2, the extent of the rewinding corresponding with the length of the typed page.
The spool may be detachably fitted upon a square shaft 66, which is removably mounted at one end in the carriage-bracket 28. The shaft may be releasably secured by a latch 61, the other end of the spool-shaft being fitted in a loose hub 68 adjoining the barrel69 which carries take-up spring 64. The hub 68 can be rotated relatively to the spring-barrel; but the extent of rotation is limited by means of a follower 18, which has finally the follower reaches the end of the groove and is arrested thereby, and this terminates the free play of the carbon-leaf relatively to the stationary spring-barrel 69.
Said barrel, however, may itself be forcibly rotated, by giving a somewhat stronger pull upon forward end trimmed ofi from time to time; while at any time the take-up spring 64 will rewind the carbon upon the spools to the extentabove noted.
The barrel 69 may also be revolved at will by means of a handle 15 extending forwardly and returned by a spring 16. This handle is connected'at its rear end to an arm 11 carrying a pawl 18, to mesh with a ratchet 19 fixed to the main barrel-hub 88, as by means of a set-screw 8| said barrel being loosely rotated upon a stubshaft 82 fixed in hub 68 and journaled in a bracket 83 that is vfixed upon the arm 28. A knob 83 is-fixed to the main barrel-hub 88, for winding{ or unwinding the carbon if desired. Said arm 11 may be connected by a link 84 to a similar arm 85, having a ratchet 86 to operate a ratchet-wheel -upon the lower spool. To-and-fro movement of the handle 15 will cause intermittent unwinding of both spools against the opposition of the friction devices.
when the entire page has been typed as at Figure 5, the carbon-leaves are found to have been withdrawn from the spools substantially to the extent permitted by the volute groove 1 I. Upon the platen being elevated and the pack being swimg forwardly and brought to a level position,-
the front ends of the work-sheets I6 may be grasped to strip them from the carbons. If the carbons should stick to the work-sheets, so that the latter would tend to pull the carbons still further forwardly, such pull would be resisted by the friction washers 13 and springs 14, so that the work-sheets would release thecarbons and not unwind the spools farther. Then the opera tor may grasp the forward ends of the carbons and raise them to the position at Figure 2 for gathering a fresh pack asabove explained.
Provision is also disclosed for making condensed records. The condensed record-sheet 81 is held permanently wrapped upon the elevatable platen-by front and rear feed-rolls 88, 89. The rolls and the sheet rise with the platen, as at Figure 3. The record-sheet 81 may be manifolded by the uppermost carbon-leaf I1.' But, if desired, amain work-sheet I6 may be laid upon said top carbon-leaf, and there may be provided for the record sheet or sheets 81 a special carbon sheet or sheets, to enwrap the record-sheets and to be permanently held interleaved'therewith by the rolls 88, 89. These rolls run upon the side -margins of the condensed record-sheets, as seen in Figure '1; the condensed record-sheet being wider than the main work-sheet I6.
The front rolls 88 may be adjusted along slots 98 in the top paper-shelf 62. The rolls 89 may be carried upon spring arms 9| adjustable along a rock-shaft 92, having a releasing handle 93 for. convenience in casting ofl the rolls, when inserting ,and withdrawing condensed record sheets. The slots 98 extend far enough out from the platen to permit the rolls 88 to be withdrawn from the condensed record sheets.
When the platen is in depressed position, as at Figure 1, it is in the control of a spring-pawl 94, which works .in the notches of the usual line-space wheel 95.
In machines of the elevating-platen class, the line-space wheel 95 is usually connected to a gear 96, which is companion to a coaxial gear 91. Both gears are shown in mesh with a common pinion 98, so that the platen is positively entrained with said line-space wheel 95. Similar gears and pinions are provided at the opposite end of the platen, as indicated at 99, I88, I8I.
In the form of the invention herein shown,
.the platen-gears 91, 99 swing up away from the pinions 98, I8I, but means is provided to keep arms I9 of the platen-swing-frame, so that it may swing down against the platen. It is normally held up by an arm I84, which is rigid with the brake, and which normally rests upon a pin I that projects from the end of the platen-shift-frame 23, which does not rise when the platen is elevated. A spring I86 throws the brake I82 down upon the platen as soon as permitted by, the pin I85. Hence the platen cannot rotate, but, after being elevated and dropped, presents the'same line of the condensed recordsheet to the types as before it is elevated.
The line-spacing "of the condensed recordsheets is effected by the handle 63, together with the main work-sheets; and since said handle 63 is employed for returning the carriage to begin a new line, it happens that the condensed record-sheets are line-spaced, and are ready for co-operation with the next inserted work-sheets.
This condensed-record-manifolding' mechathe platen is elevated to clear the sheets, in'a' machine in which the platen-gears are drawn away from their companion gears. However, the condensed-recordinvention is also applicable ments may be used without others.
