TYPEWEITING MACHINE.

Application filed October 3, 1925. Serial No. 60,190.

This invention relates to interponent or shield devices for typewriting machines and methods of using same, for preventing certain characters typed on a work-sheet from being carbon-copied on an underlying record-sheet.

Many business firms have their checks and drafts arranged in sheet form for conveniently typing the payees names and amounts of the checks and making a record of the checks on an underlying record-sheet at the same time. It is usual for check register or record sheets to bear only the payees name and the numerical amount of a check both in a single line. To save space, it is desirable to have the lines of record data of several checks spaced much nearer each other on a record-sheet than they are on the usual check-sheet.

To these ends, provision is made in the present invention, of a paper chute or table mounted on a typewriter carriage and arranged with forwardly-projecting side flanges positioned apart approximately the width of a sheet of checks. On each side of the table may be positioned a usual up per feed-roll of an Underwood typewriting machine. There is further provided a thin interponent or shield which may consistrof a rectangular cardboard strip having two narrow transverse slots extending from a long edge of the strip to within a short distance of the opposite side and positioned so that the shield may lie close against the table body with said slots engaging around said flanges; the closed ends of the slotsengaging under the lower ends of the flanges, and

the lower edge of the strip coming a short distance above the printing line.

A check-sheet overlying a wider record sheet interleaved with carbon may be inserted from the rear around the platen; the check-sheet and carbon being passed in front of the table and the record-sheet behind it and under the feed-rolls at the sides of the table. The shield maybe pushed. at will below the printing line to prevent characters typed on a check-sheetin front of the table from being carbon-copied on the recordsheet. A feature of the invention is an arrangement for raising the shield by linespacing the work-sheets. By releasing the usual lower feed-rolls, the check-sheet may be advanced while the record-sheet is held stationary by the upper paper feed-rolls,

a short distance around the platen from the position of the sheet in Figure 1.

Figure 1 1s a fragmentary front view of the same, showing the work-sheet advanced for printing a second line of characters thereon; the shield being lowered behind the second line.

Figure 5 is a diagrammatic view of a sheet or web of bank check slips.

A typewriter platen 10011 a shaft 11 mounted in carriage side frames 12 may have linespacing means including a fingerwheel 13 and a ratchet-wheel 14:, the latter operated by a finger-piece mechanism, not shown. Two feed-rolls 17 engaging against the upper side of the platen 10 are carried by fingers 18 fastened to the arms 19, the latter being slidably and pivotally mounted on a platen-carriage-rod 20. Feedrolls 21 and 22 are mounted on feed-roll.

rods, not shown, and are arranged to be thrown against or away from the lower side of the platen 10 by means, not shown. A paper-table 23 may have an apron extension 2 1 under the platen. The above-described parts may be the same as on an Underwood typewriting machine.

A paper table or chute 30, having two forwardly-extending flanges 31, arranged for serving as side gages for worksheets, may be supported by two arms 32 fasten side frames 12, so that the lower edge of the table may be in close proximity to the platen, say about 15 above the printing line. Back or body portions 34: of the table may be slightly inclined rearwardly.

A rectangular interponent or shielc 35 made preferably of relatively hard flexible ltltl cardboard'has two narrow slots 36 extending transversely from its top edge to within a short distance of its lower-edge 35, provldinga pair of parallel vertical tongues 35,

35", which slots are spaced apart a distance that permits the shield to lie close to the front face of the table 30, and substantially tangent to the platen 10 at the printing line with the slots 36 engaging around the flanges 31. In the assembled position on the table the closed ends of the slots 36 are below the lower extremities ofthe flanges 31, which thus limit the upward movement of the shield. Of course, the shield could also be made higher and have the slots closed above as at the bottom in order to increase its durability and allow its inversion,

A plurality of bank checks 40, 40 etc., may be fastened one below another along perforated lines 41, to form a sheet 42 having a width slightly less than the distance between the'flanges 31. For conveniently writing .data, on the checks and making a condensed record of them at the same time, the check-sheet 42 with a wider underlying record-sheet 43 and an interleaved carbonsheet 44 may be inserted around the platen 10 from the rear,- in the usual way. The

1 three sheetsmay be advancedtogether as 7 far as the loweredge of the shield 35. There the check-sheet 42 and the carbonsheet. 44 will be passed in front of the shield 35 and advanced to bring the first or leading checkin-posit-ion for typingthe payees name and the numerical amount of the check. The record-sheet will pass below and behind the shield and under the feed-rolls 17 positioned at either side of the paper table 30. In this position, the lower edge 35 of the shield maybe held by friction between the work-sheetsand the shield far enough above .After writing the amount; of the check in j words, which the shield prevents being carbon-copied, the carriage may be moved to the right by the carriage finger-piece, not shown, and thepla-ten line-spaced thereby as usual in an Underwood typewriter. The platenlO maybe furtherline-spaced by manipulation in the usual way. The lower portion ofthe, shield 35', at the beginnin of these line-spacing operations, is held t-ig tly between the carbon-sheet 44rand the recordsheet 43 and may be moved upwardly above the printing line by friction of the moving sheets. The feed-rolls 21 and 22 may now be thrown ofl, and the check-sheet pulled ahead to bring the second check 40 to proper position for having its payees name and the numerical amount typed as previously done on the first check 40. The record-sheet 43 is held against movement by the feed-roll 1.7 while the second sheet is advanced. For holding the check-sheet 42 closely against the face of the shield 35, to increase the friction'between the two, a finger-piece 54, more fully described in the patent granted to me March 18, 1924, No. 1,487,671, may be used. Checks may be severed from the sheet or web 42 when they have been typed, and advanced above the paper-table or after the sheet has been removed from the machine and the checks have been dated and signed.

It may sometimes be desirable to withdraw the shield from the printing line without line-spacing the record and check sheets. In such a case, it is but necessary to seize the end tongues 35, 35 of the shield and thereby carefully draw the shield upward until the bottoms of the slots engage the tableflanges, as already mentioned. The tongues may thus be considered as integral handles for the shield, in addition to their other office of assisting to guide the shield by their inner edges engaging the table-flanges.

By the above-described means and the method of using the same, a greater number of checks can be recorded on a sheet, than if the record-sheet and check-sheet were advanced around the platen together in the usual way. Although described in connectionwith the typing of checks and similar instruments, it can be readily seen that the herein-described devices may be advantageously used for other work.

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

Having thus described my invention, I claim:

1. In a typewriting machine, the combina tion with a carriage and a platen, of a papertable mounted on said carriage above said platen and having forwardly-extending side flanges, and a type-blow-rcceiving shield movable up and down against the face of said table and extending downwardly substantially tangent to said platen at the printing line thereof, said shield having two narrow, open guide-slots extending ownwardly from its top edge and arranged to engage around said flanges from below.

2. A typewriting machine including the combination with a rotatable platen and a work-table disposed above the same, of a shield slidable on said table and arranged tangent to the platen, means on said table to guide said shield in advance movement, and means on said shield below the leading said table to stop said shield in movement a distance beyond the printing line.

4t, A typewriting machine including the L combination with a rotatable platen and a work-table disposed above the same, of a shield slidable on said table and arranged tangent to the platen, there being side flanges on said table to guide said shield in advance movement, and integral side tongues on said shield for engaging the lower extremities of said tableflanges to stop said shield in a position beyond the printing line.

5. A typewriting machine including the combination with a rotatable platen and a work-table disposed above the same, of a shield slidable on said table and arranged tangent to the platen and having integral tongues projecting upwardly to serve handles whereby to withdraw said shield from the printing line, there being means to guide said shield in movement on said table.

6. In a typewriting machine, the combination with a carriage and a platen, of a papertable mounted on said carriage above said platen, there being forward projections on said table, and a type-blow-receiving shield movable along the face of said table and ex tending downwardly substantially tangent to said platen at the printing line thereof, said shield having two relatively narrow slots disposed in parallel relation to the sides of said shield and arranged to engage said table-projections.
