TYPEVRITING MACHINE.

Application filed June 16, 1919. Serial No. 894,532.

To all whom it may concern.

Be it known that I, Jnssn A. B. SMITH, a citizen of the United States, residing in Stamford, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Typewriting Machines, of which the following is a specification.

This invention relates to typewrltlng ma- 1 chines, and is herein disclosed as applied to.

an Underwood standard typewriting machine.

The invention is herein disclosed as embodied in a device adapted to facilitate the simultaneous entering of single items upon a bill head and a ledger sheet, and more especially adapted for use in such work where a single item only is entered daily on each bill and the ledger sheet.

In order to facilitate making such entries, it is advantageous to have an end gage which is adapted to be positioned in'the machine,

so that a work-sheet, for example a bill, may

be gaged thereagainst, in a predetermined 2 position and so that another work-sheet, for

example a ledger sheet, may be gaged against another end gage settable with reference to the first gage, thus enabling the sheets to be inserted with a minimum of labor, conducing to accuracy and rapidity of work. T

In order to enable a typewriting machine used for this work to be also used for other purposes, it has been found advantageous to provide a special paper table at the rear of the 1 platen, forward from the usual paper table in spaced relationthereto and adapted to carry the gage for the work-sheet, and so positioned as to guide the work-sheet down Other features and advantages will here In the accompanying drawings,

Figure l is a perspective view of an Underwood standard platen frame or shift frame, showing my invent-ion as applied thereto.

Figure 2 is an enlarged section of the end gage, and the meanswhereby it is adjusted.

Figure 3 is a sectional side View of the parts shown in Figure 1, and showing a ledger sheet positioned.

Figure 4 is a view similar to Figure 3, but showing the feed-rolls effective, and a bill gaged againstthem Figure 5 is a view similar to Figure 4:, but

showing the ledger sheet and. the bill advanced to the printing point.

A work-sheet 10, which may be a ledger sheet,,is passed around the platen,11,'which is journaled in the ends 12 of the usual Underwood shift frame, by being slipped down over a paper-guide which may be a second paper table 13, mounted upon brackets 1 L springing from the ends .12 of the shift frame and lying between the platen 1'1 and the usual rear paper table 15. The paper table 18 may be considerably narrower than the platen 1 1 and rear paperjtable 15, and

advantageously extends down below the cross piece 16, which is fast to it andwhich supports it upon the brackets 14. The paper table 13. as clearly seen in Figures 3 and 4, terminates considerably short of the platen l1, and above the point where the usual paper table 15 terminates, thus leaving a clear space between the two tables for the insertion of ordinary work-sheets.

When the. work-sheet 10 is slipped down upon the paper table 13, it strikes the lower end 17 ofthe paper table 15, and is bent forwardly to pass between the usual rear feed roll 18 and the platen 11. and from thence swings forwardly above the front feed roll- 19, up past the printing point'indicatedin Figure 5 to the point at which the lowercase types 20strike against the work-sheet. Wheninserted in this manner, the trailing edge of the work-sheet 10 may begaged against atransverse bar member forming an end gage 21. whlch is formed as an L on a plate 22, said plate being adjustably fast c ded o h en y means of th m -nuts 23, which are adapted to be screwed up upon screws 25 extending through openings 241 in the table 13, to draw down the plate 22 upon the face of the table. When thus adjusted, the work-sheet 10 is gaged at its trailing edge by moving the work-sheet upwardly against the L end gage 21, gaging it beneath a pair of lightly pressing spring clips 26, which bear upon the front of the table 13 or upon a front extension 27 of the plate 22.

The work-sheet 10 may be further gaged at this time'by means of the side gages 28,. which are shown as termed of turned-up ends of the extension 27. In order to facilitate the rapid centering of the work-sheet 10, the lower ends 29 of the side gages 28 may flare outwardly, and to enable the work sheet 10 to be easily handled, the side gages 28 may be only just long enough to give a good bearing for the edge of the work-sheet.

The feed-rolls 18 and 19 may now be drawn against the platen by operating the usual casting-off handle 32. When a worksheet has been thus adjusted and is held in place by the clips 26 and feed-rolls 18 and 19, a second work-sheet 30, in the form ota bill head, together with a carbon 31, maybe inserted, usually between the worksheet 10 and the platen 11. as shown in Figure 4, although obviously if desired the worksheet 30 and carbon 31 may be insorted, in proper relation, at the back of the second paper table 13 and on theusual paper: table 15, which forms a part of the usual platen vframe having the ends 12. The work-sheet 30 may be'passed downwardly until it seats itself against the bite of therearieedrolls 18, which, in this way, form a leading edge gage for the sec ond -work-sheet. When the work-sheets have been thus brought to the proper position relatively to each other by rolls or 'gages'18 and the gage 21, the platen may be rotated-forwardly either by actuating the usual line-spacemechanism. which includes the linespace wheel or by rotating the knob 34 until the line to receive the typewritten matter is at the printing point where the types 20 can write upon it. It is to be noted that the rear feed-rolls 18 may serve as a leading-edge gage for a worksheet inserted t'rom the rear the front of either of the paper tables 13 to 15.

Owing to the fact-that the clips 26 hold the first work-sheet lightly, the two work- "sl'ieets'advance together to 'the printing pointat the-turning of the platen. After v the desired line of writing has been written.

the work-sheetsare-removed from the ma- $111118, "and another first and second worksheet-10 and 30 are inserted in the same manner.

-It wi-lhbeobserved that the device is of especial'utility whereentries are to be made at a. distance from the of: a arge numgage 21 may be adjusted to suit this distance, viz, the distance from the end gage 21 to the writing line upon the bill 30, when the latter is gaged against the feed-rolls 18.

To facilitate the rapid and accurate adjustment of the end gage 21, a suitably graduated scale may be provided at each end of the table 13, the graduations being co-ordinated with the position of the line to receive the printing upon the bill head 30 when the latter is gaged against the feedrolls 18.

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