TYPE-WRITING MACHINE.

Patented Dec. 19, 1916.

Application filed May 15, 1914. Serial No. 838,634.

To all whom it may concern Beit known that I, Lnsrnn A. "WERNERY, a citizen of the United States, residing in .Brooklyn borough, in the county of Kings,

city and State of New York, have invented certain new and useful Improvements in Type-\Vriting Machines, of which the following is a specification.

This invention relates to attachments for typewriting machines, and one of the features of the invention is the provision of novel means for simultaneously feeding a number of work sheets past the printing line at different speeds.

The invention further provides means which may be brought into activity at will for feeding all of the work sheets together, and at the same speed.

In various kinds of work in which several copies are simultaneously made, it is desir able to feed the original sheet or work-form at a different speed from that of the other copies. For example, in writing bills or other statements, usually written on printed forms, duplicates being simultaneously written on a ledger sheet or other record sheet, it is often desirable to condense the record copy by making the line space distances thereon only a fraction of those on the original copy, and also by reducing on the record copy the space between succeeding state ments.

In some kinds of work also it is desirable to condense a portion only of the record copyand to make the line-spacing of other portions the same as on the original work forms. For example, in writing checks, a number of items or amounts covered by the face \alue 'of the check are sometimes written at single line-space distances on a stub at one end of the check/ In this instance, these items should .be spaced the same on the record copy as on the original, while the items written on the check itself may be con: densed on the record copy. The present invention is well adapted for such work and, in general to any work as the work sheet feeding mechanism may be instantly adjust-' ed either to feed the work sheet at the same speed or at different speeds.

In general, the invention is adapted for any work where it is desired in making sev' eral copies at, once to make the line-spacing on one copy or any portion of a copy, different from that of the other copies.

In carrying out the invention, a main feed roll may extend along the platen in contact therewith above the printing line, and may be positively driven at the samespeed as the platen by means of a gear and a pinion connected respectively to the platen and said feed roll. An auxiliary feed roll may also extend along the front side of the platen, by which is meant the exposed side,

the platen. Such gearing may comprise a gear and pinion'running in mesh and connected respectively to said main and auxiliary feed rolls. Cooperating with the said auxiliary feed roll, are pressure rolls supported by hangers depending from a rock shaft which may be rocked by a key thereon to lift said pressure rolls, and each of said pressure rolls maybe individually lifted by swinging its hanger on said rock shaft; The original work-sheet may extend over the printing line and be held between said auXiL iary feed. roll and pressure rolls, and a record and carbon sheet may be held between the said main feed roll and platen. In order to feed all of the work-sheets at the same speed, when desired, additional feed rolls are located below the printing line to hold all the work sheets on the platen,'but said additional rolls are held away from the platen while the work sheets are being fed at different speeds.

The feed rolls of my attachment mounted in a swinging frame pivoted 1n brackets on the ends of the platen frame, so

that said frame may be swung upwardly and I rearwardlyto carry the'rolls to inactive po: sition, where they will not interfere with the operation of the machine in the usual way. A spring tive to hold it in either position.

Other features and advantages will hereinafter appear;

In the accompanying drawings, Figure 1 is a part sectional front perspective view of an Underwood typewriter carriage with the present invention applied thereto. Fig. 2 is a perspective view of the mechanism at the left-hand end of the carriage. Fig. 3 is a sectional elevation taken near the right-hand end of the platen, the auxiliary sheet feeding may be connected to said frame is operaplaten and preferably comprising an outer attachment being swung back to inoperative position, permitting the machine to be used in the usual way. Fig. 4 is a similar view showing the attachment swung forward and .the feed rolls arranged to advance the worksheets at the same speed. Fig. is a similar view but with the feed rolls arranged to adplaten axle 2 journaledin "the ends 3 and 4 of the platen frame, which also comprises an inclined paper shelf 5 connecting the frame ends and located at the rear side of the platen. The platen frame is mounted in'a carriage 6 which may be driven in letter-feed direction by the usual spring motor (not shown), the platen being shiftable to upper and lower case positions, as is usual in the Underwood machine. Type-bars 8 actuated in the usual manner, are provided with upper and lower 'case types to strike against the front face of the platen, or the work:

wheels. 9 secured to the endsof the platen axle, or by the line-spacing mechanism comprising a hand lever 10 pivoted at 11 and having an arm 12 to move rearwardly a slide bar 13. A pawl 14 pivoted at 15 to the slide bar, has a tooth to engage the line-space ratchet wheel 16 and rotate the platen as the slide '13 is moved .rearwardly. The usualspring-pressed detent 17 .bearing against the :iteeth of the wheel 16. holds the platen at li'l'i'e 'space intervals. The-number of linespace' intervalsthrough which the platen is rotated by the operation of the lever 10 is determined by the adjustment of'the lever 1 8 provided with a ledge 19 to hold the. dog

machine.

work-sheets past the printing ma .be in the form frame having ends 21 connected by pivots 22 tobracket arms 23 formed integral; with, or 55 otherwise secured to'the frame ends'3 and 4. A pressure roll 24 for feeding one or more of the work pieces at the surface speed of the platen, comprises a shaft journaled at its ends in the frame ends 21, said roll eX- tending along the upper surface of the sleeve of rubber orother suitable friction materlal. The pressure roll 24- may, in some instances, be driven by frictional contact with the platen or a work-sheet 'on the' .work-sheet (and additional sheets, if desired) at a different speed from the sheets fed by the roll 24, comprises an auxiliary or secondary feed roll 27 also journaled at its ends in the frame ends-21, and driven by a gear wheel 28 on the roll 24 meshing with a pinion 29on the roll 27. The pinion 29 is smaller than the gear wheel 28, so that the peripheral speed of the roll 27 is greater than thatof the roll 24. In the particular construction shown, .the speed of the two rolls is in the ratio of two to one, although the ratio may obviously be varied as desired and the roll 27 might be run slower than the roll 24.

Running with-the feed roll 27 are a number of pressure rolls 30 mounted in hangers 31 depending from a rock shaft 32. Each of these hangers comprises a 'U-shaped bracket 33 having hearings on the shaft 32, and yieldinglyheld against rotation on the shaft by means of a cam roller 34, the ends of which. are mounted in elongated openings 35 in thesaid bracket, the roller 34 being pressed by a leaf spring 37 into a cam groove 36 extending. longitudinally in the under face of the shaft 32. Each roll 30 is journaled in cars 38 formed on a depending spring-arm 39 secured to the bracket 33 by screws 40, which also secure a bracket 41. through which is threaded an adjusting screw 42, the end of which bears against pressure of the roll 30 against the feed roll 27 may be adjusted as desired. Each roll -z- 3O: .forms with the roll 27, a feeding couple The parts above described, may be ille isame as are usually found-on the Underwood Y atrthe front side of the platen, that is, the

- exposed side of the platen.

The rock shaft 32 is mounted in brackets 43 rigidly securedto the platen frame ends, and, since it is disposed above the feeding couple, acts to prevent the outer or original work-sheet or sheets from falling forwardly away from the platen. The brackets 43 are of substantially the same construction as the brackets 33, and also provided with cam rolls 34 seated .in the groove 36, and leaf springs 37, so that the rock shaft is yieldingly held in operative position. The brackets 43 may be mounted on spacing blocks 43", attached to the frame ends 21 by thumb screws 43*. A finger lever 44, se-

cured to the end of the rock shaft, operates,

when depressed, to swing the hangers 31 outward to the Fig. 4 position, thereby separating the pressure rolls 30 from the roll 27 to permit a work-sheet 45 to be readily introduced between the rolls 30 and 27.

Before positioning the. original worksheet 45, the duplicate sheet or sheets 46 and carbon sheet or sheets 47 are placed in position between the platen and feed roll 24.

vThe attachment may be bodily swung up- The attachment frame is held in either position by a spring or springs 61 connected at one end of the platen frame, and at the other end to a part of the swinging frame, as for example, to the shaft of the roller 24.

In order that all of the work-sheets may feed together and at the same speed, or the feed quickly changed from an equal speed for all of the sheets to unequal speeds, or vice versa, front and rear pressure rolls 48 and 49 are located beneath the platen and shiftable to and from theplaten, so that they may feed the work-sheets when. the auxil ary rolls 30 are lifted from the roll 27. The rolls 48 and 49 are mounted on levers 50 pivoted on a rod 51, which may be a tie-rod of the platen frame, said levers 50 comprising arms 52 straddling a rock shaft 53 provided with flats 54 which permit the rolls 48, 49 to be held against the platen by springs 55. When the shaft 53 is rocked, the arms 52 are spread, and the rolls thereby lifted from'the platen. The

shaft 51 is rocked by means of a finger lever 56 connected through a link 57 to -a rock arm 58 on the shaft The pressure rolls 4S and 49 are self-holding in released position. i

InFigs. 1 and 5, the parts are shown. in position for feeding the original and duplicate sheets at different speeds. If the linespace adjusting lever 18 is set to permit the duplicate sheet to be fed a single line-space distance at each operation of the line-space lever, the original sheet 45 will be fed through two line-space intervals, at each operation. Such arrangement is useful in various kinds of work, as for example, in filling out checks, bills or other blank forms which constitute the original work-piece, when it is desired to make the duplicate in condensed form on the ledger sheet or other record sheet.

If it is desired that certain portions of the work shall be equally spaced on both the original and duplicate sheets, as for example in making a condensed list of items on the original sheet, the feed of the device may instantly be changed by depressing the finger piece 44 to throw off. the pressure rolls 30, and by turning the finger piece 56 to throw the feed rolls 48, 49 up against the platen. Said feed rolls then serve to feed the original sheet at the same speed as the duplicate sheet.

To illustrate one use of the invention, the following example is given, showing the method of using the invention in writing a check and making a condensed record copy thereof. For use on typewriting machines,

it is customary to print the blanks on sheets of a size to be placed on the machine, the blank forms being arranged one beneath another on the sheet. when filled out, may appear as follows:

UNDERWOOD BANKING COMPANY.

New York, Jan. 26, 1914. Pay to the Order of Henry Smith $100.00 One Hundred and 00/100 Dollars. No. 7564.

On the record sheet it will appear as follows:

Jan. 26, 1914.

Henry Smith 100.00 One- Hundred. and 00/100 In. this instance, the items on the record sheet are condensed as well as the spacing between the successive checks being reduced, so that the space required for each check on the record sheet is only half that of the original check. In this. case, it is unnecessary to change therelation of the feed rolls, the arrangement shown in Fig. 5 being retained throughout the writing of a series of checks.

The above example is given merely to illustrate one of the uses of the invention, and not to indicate its scope, as the invention is adapted for a great variety'of Work,

and various methods of use.

Variations may be resorted to within the scope ofv the inventlon, and port1ons of the improvements may be used without others.
