JOHN WALDHEIM, OF ELIZABETH, NEW JERSEY, ASSIGNOR TO UNDERWOOD TYPE- WRITER COMPANY, OF NEW YORK, N. Y., A CORPORATION OF. DELAWARE.

TYPEWRITING MACHINE.

Application filed April 9,

To aZZ whom it may concern:

Be it known that 1, JOHN WALDHEIM, a citizen of the United States, residing in Elizabeth, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Typewriting Machines, of which the following is a specification.

This invention relates to typewriting machines, and more particularly to the kind used for continuous billing, shown in the patent to Vernery 8: Smith No. 1,132,055, of March 16, 1915, in which a folded pack of work-sheets or webs with interleaved carbon-sheets may be fed around a platen to the printing point; the carbon-sheets being attached to a carrier to enable them to be shifted to untyped portions of the workwebs.

The webs or continuous work-sheets usually have printed forms'thereon and may be drawn forwardly, after they have been typed, to a gage, prior to severing the typed forms from. the pack of continuous sheets.

The printed forms on the various sheets may include instructions differing from each other, according to the several uses for which the copies may be required. *For example, the original or outer sheet may be sent to the customer. while the various copies may be intended for different'departments. It is therefore desirable to be able to readily distinguish the various copies to facilitate their sending to the various places for which they are intended. To do this, it has been proposed to print the ruled forms and their respective instructions on the various continuous work-sheets in different colors. It has also been proposed to use work-sheets in which the materials are of different colors, in which case the forms may be printed thereon with the same colored ink. This last-mentioned method, however, necessitates the making of different worksheets separately, due to the differently colcred materials.

The object of the present invention is the provision of means to accomplish the desired result without necessitating the printing of. the forms with different kinds of ink, or the making of the work-sheets of differently colored materials.

For this purpose. I arrange to .provide the various forms with marks of identifica- 1920. Serial No; 372,445.

brought to the printing'point when the carbon-sheets are retracted, prior to the writing of a new set of forms, so that the first entry typed on each set of forms, which may be an order number, may appear in different colors on the various forms.

In typing the body of the forms, it is sometimes desired to make certain entries other than the first entry stand out from the others which are typed in black. For this purpose, such entries may be typed on the outer sheet through-the red field of the usual bichrome ribbon. To have this entry appear differently on the various carbon copies, the

carbons may be shifted relatively to the work-sheets, prior to making the entries, to bring the narrow fields of different colors to the printing point.

'In some cases, where instead of having such entries appear in different colors, it is desired to have them appear in red as on the original, each carbon-sheet may be provided with another narrow field which may be red in color and adjacent to the other narrow field, all of the red fields being collectively shiftable to the printing point at will.

In the continuous billing machine, it is also desirable, at times, to type on the outer work-sheet, which is done through the usual ribbon, without reproducing the typewritten matter on the carbon copies. I

For this purpose, provision is made to permit the carbon-carrier to be retracted to an abnormal position to bring the leading edges of the carbon-sheets below the printing point, thereby rendering them ineffective for copying purposes.

To permit the carbons to be retracted to bring the narrow fields to the printing point, or to permit the carbon-sheets to be rendered ineffective, there may be provided a plurality of settable stops to co-operate with a relatively fixed stop to arrest the carbon-carrier in different positions when retracting the carbon-sheets.

The invention further relates to means to facilitate the assembling of the carbonsheets on the various holders of the carboncarrier, so that the difi'er'ently colored fields of the various carbon-sheets -may register with each other.

The invention may also be used to increase the use of the carbon-sheets since the carbon-carrier may be arrested in different positions, thus enabling the spaces between the typg positions on the carbon-sheets to be use Other features and advantages will hereinafter appear.

Figure 10 is a perspective view as seen from the back of a portion of the carboncarrier with the settable stop-member and the relatively fixed stop.

Continuous work-sheets 15, which may be folded to form a pack 16, as shown in Figure 6, and shown as separate sheets, for clearness, in Figures 1 and 7, may be inserted in the machine. The work-sheets may be led from any suitable source of supply over a rear rail 17 of an auxiliary carriage frame 18, comprising two end bars or rails 20 and 21, connected to travel with a platen-carriage 22.

The work-sheets 15v may be extended forwardly over a carbon-sheet-carrier.or carriage 23, supported on the end rails 20 and 21. Carbon-sheets 24 are interleaved between the work-sheets 15, and extend forwardly from the carbon-sheet holders 25 on the carbon-carrier; The work-sheets and the carbon-sheets pass over a. shaft 26,'supported on the platen-carriage, and extend downwardly around a platen 27 and between feed-rolls 28. At the front of the platen, the work-sheets and the carbon-sheets are guided upwardly past the printing point, so that they may be typed upon by the typebars 29, the outer work-sheet receiving its impressions through an inking ribbon 30, which may have a black field 30 and a red held 30*, while the inner work-sheets receive their impressions through the interleaved carbon-sheets 2 1. The platen is mounted on a platen-shaft 31, rotatably mounted, so that the worksheets may be linespaced, in a frame 32, which may be swung about the axis of a rod 33, supported in suitable brackets 34011 the platen-carriage, for a purpose hereinafter described.

To line-space the platen after each line is typed on the work-sheet, there may be provided the usual line-space lever 35, which swings, when operated, about a pivot 36, to cause a toe 37 thereon to push a line-space slide 38 rearwardly. The line-space slide is provided wit-ha pawl 40 to engage the teeth. 41 of a ratchet-wheel 42 to rotate a shaft 13, supported in the carriage 22. The shaft 4-3 has secured thereto, atv its inner end, a gearwheel 44L, meshing with a pinion 15, revolu bly supported on the rod 33; said pinion being broad enough to engage with a gearwheel 46, adjacent to the gear-wheel 44. The gear-wheel 46, however, is secured to the platen-shaft 31, which is normally in alignment with the line-space shaft 43. Thus, as the gear-wheel 4-1 is rotated, the line-space movements are transmitted through the pinion 15 and the gear wheel 4:6 to the platen to feed the worksheets forwardly.

ne work-sheets 15'l1l2tjf be furnished with printed forms thereon, which are of equal length. and extend lengthwise of said sheets. After the entries are made on each set of forms, the set may be'severed by a knife 47' (Figure 7), supported in the swing-frame32, and extending lengthwise of the platen'27. Since the printed forms are of successive equal lengths, and the number of entries may vary on the different sets of forms, it is necessary to first gage the forms prior to severing. It is also desirable to retract the carbon-sheets 21 to bring them to the next succeeding set of forms, and their leading edges below the cutting edge of the knife before severing.

-To facilitate the shifting of the carbonsheets relatively to: the work-sheets, thev platen may be displaced by the swingframe 32, which is locked in printing position (Figure 7), by hooks 48 and 50 on the shaft 26, which is spring-operated to hold the hooks 48 and 50 over studs 51 on the swing-frame.

To release the swing-frame the hook 50 is provided with a finger-piece 52, which may be pushed rearwardl to move the hooks 48 and 50 out of holc in relation with the studs 51 on the swingrame. The typist then grasps a front paper-table 53, forming part of the swing-frame, to swing said frame about the axis of the rod 33, to raise 7 lower the platen to typing position, While the work-sheets are held against the gage- -bar with their leading edges against the gage 54. After the frame has been swung back, the set of typed or finished forms may be severed from the pack, by pulling them crosswise of the knife 47.

Provision is made to make distinguishing marks on the ,various typewritten forms after the sheets have been inserted in the machine. This may be done on each set of riage), may be provided each with a comparatively narrow field or coated surface 60, differing in color from the color of the coating which may cover the balance of the carbon-sheets to form wide fields 61, which may be black in color. The narrow fields 6O, differing in color from each other, may be brought to the printing point whenthe carbons are retracted or shifted relatively to the worksheets. For this purpose, the stop-member 57 is provided, which may be pivoted to a bracket 62 on the carbon-carrier 23, so that a co-operative stop 63 thereon may be set into range of the stopv 58 to engage, on the return'stroke of the carbon-carrier, with the relatively fixed stop 58, thus bringing the differently colored fields 60 to the printing point (Figure 4), or, in other words, rendering them effective. The first entry may then be typed and copied on the inner sheets in different colors through the narrow fields 60 of the carbons, the different colors serving as distinguishing marks for the various Worksheets. The entry on the outer work-sheet may be. made through the black field of bichrome ribbon 30. The line-space handle is next operated to feed the work-sheets and the carbons forwardly, thus bringing the black fields 61 of the various carbons into use for the balance of the entries to be made.

' It should be understood that the fields of different colors may be rendered effective at. any time. For example, if it is desired to make an entry appear in different colors after several entries havebeen typed, the platen may be lifted to permit the carbons to be shifted to bring the narrow fields to the printing point, but, instead of pulling the work-sheets to the gage 54, they may be held tightly against the table 53, or gage-bar 55, while the carbon-sheets are shifted by pushing the carbon-carrier 23 rearwardly, the stop 63 having previously been set into effective relation with the fixed stop. The platen is then swung down, when the entries to appear in different colors on the various work-sheets may be made, after which the succeeding entries appear in the same color as the preceding. entries.

As previously stated, the body of each carbon-sheet may be black, so that the greater part of the typewritten matter may appear in black on the various forms. It should be understood,however, that the differently colored fields may extend over the greater part or the whole surface of the carbon-sheets.

The carbon-sheets 24 may be held on their respective holders 25, by clips 64, pivotally supported on the holders. It will be seen by an inspection of Figure 1 that the carbon-sheet holders 25 are placed side by side and successively further away from the platen. It is desirable, however, to assemble the carbon-sheets on the holders so that the fields 60 on the various carbonsheets may register with each other. For this purpose, each carbon-sheet may be provided at its edges with markings 59, so that the corresponding markings on the opposite sides of the carbon-sheets may be used to position the latter on the holders by bringing the markings in line with the back edges of the holders. The markings are spaced apart from each other distances equal to the distance between the back edges of the successive holders, so that any carbon-sheets may be secured to any one of the holders, the set of markings used to position the carbon-sheet depending on the position the holder is to occupy on the carbon-sheet-carrier when attached thereto.

Sometimes it is desirable to type a set of forms without distinguishing :marks.

To'do this, the stop-member 57 may be set to a different position to bring a stop 65 thereon into effective relation with the fixed stop 58, so that the carbon-carrier may be arrested earlier during a carbon-sheet-retracting operation, so that the leading edges of the black fields 6 1 are brought to the printing point; the differently colored fields thus falling short of being brought into use, as shown in Figure The set of forms may now be typed to have the typewritten matter appear on the various copies in the same color.

It is also desired at times to typewrite matter on the outer work-sheet which is not to appear on the carbon copies. For this purpose, provision is herein made to shift the carbon-sheets 24 during the carbon-retracting operation to bring their leading edges below the printing point, thus rendering them ineffective, as shown in Fig ure To do this, the settable stop-member 57 is provided with a stop 66, which may be set into efi'ective relation with the relatively fixed stop 58, to permit the carbon marriage to be moved rearwardly a greater extent to an abnormal position, to bring the leading edges of the carbon-sheets out of range of the printing type-bars 29. The operator may proceed to type the entry which may be made on the outersheet through the ribbon 30, without transferring the type impressions to the inner worksheets.

It should be understood that the differently coloredfields 60 of the carbon-sheets may be made wider, so that they may remain in use for several line-space movements of the platen. The leading edges of the carbon-sheets may also be drawn a greater distance below the printing point,

so as to allow several lines to be typed on .the outer sheet before the carbons are brought into use. This may be done by having the stops 65, 63 and 66 spaced further apart from each other to increase the extent of the rearward movement of the carbon-carrier.

To facilitate the setting of the stop member 57, so that the carbonesheet-carrier may be arrested to render the black fields 61, or the differently colored fields 60 of the carbon-sheets effective, or bring the carbonsheets to a non-copy or inefliective position, indicating means may be provided. The indicating means may comprise an index plate 62 forming the upper part of the bracket 62, and having the marks B D and N, respectively, for the blacli color, distinguishing colors and non-effective positions of the carbon-sheets; the stopmember 57 being settable by means of a handle 67 and an indicator 6-8, which may point to B, D or N To hold the settable stop-member 57 in any one of its positions, it may be slightly resilient and other.

provided with a projection 70, to snap into any one of aplurality of holes 71 in the supporting bracket 62.

To enable copying on the various worksheets in red or in various colors at the same time, the carbonsheets may each be provided with two narrow fields and 72, as shown in Figure 6, thus forming sets on the various carbon-sheets, the set of fields 72 nearest the leading edges of the carbons being-of the some color, which may be red, thus ditl'ering from the black fields 61 of the carbons and from the differently colored fields 60. It will be seen that with appropriate markin s on the index plate 62*, the stop-member 5 may be set, so that the carbon-sheets may be selectively positioned so as to bring the various sets of fields 61, 60 or 72 to the printing point.

A further use of the invention may be to increase the period of usefulness of the car-.

surfaces, have become worn. by the typebars 29, the'carbon-carriage 23 may be permitted to move back a little further, as in Figure 8, and be arrested by the stop 74, thus permitting the unused portions between the used portions of the carbon-sheets to be brought into use, the unused portions being brought successively to the printing point byline-spacing the platen 27.

It will be seen that the stop 58 is not merely a stop but that it also serves as a master gaging device, and. that since it determines a definite location for the carbons while the gage 54L determines a definite position for the work-webs, the two gages 54: and 58 co-operate to locate the work-webs and carbons definitely with relation to each The stepped stop device serves as an auxiliary gage to vary, by mechanically predetermined amounts, the position of the carbons relatively to the master gaging device 58, such variations corresponding to the widths of the narrow color fields.

-Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
