TYPEWRITING MACHINE.

Application filed December 22, 1920. Serial I To. 432,376.

To all whom it may concern:

Be it known that I, Jnssn A. B. SMITH, a citizen of the United States, residing at 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 sheet collating means, and is an improvement on my copending applications Serial .No. 405,018, filed August 21, 1920 (now Patent No.

1,489,224, dated April 1, 1924), and Serial No. 407,651, filed September 2, 1920. The invention is shown applied to an Underwood standard typewriting machine.

It is one feature of this invention to provide proper guiding means for sheets of different widths such as astatement-sheet and a ledger-sheet. A ledger-sheet usually containsall the matter found on the statementsheet'and in addition is provided with an extra column or two for the transfer of old balances, etc. Thetwo sheets may therefore be aligned along the same gage at one edge, but separate gages mustbe provided at their othenedges corresponding to the different widths. Since the wider sheet must-pass beyond the gage of the narrower sheet, said gage is made of less height than the other gages so that the wider sheet may pass thereover and contact with an extra gage having a. flange of greater height. It will be seen that the gages for the wider sheet form with the rear paper-table a guiding chute, and

machine of this type tends to obstruct access to the tabulator stops or to the selectors of a computing machine, it is a featureiof this invention to provide a pivoted rear papertable capable of: being swung forwardly to allow such access. Means are provided for locking the paper-table in its rearward position.

A further feature is the provision of novel means for pivotally mounting the rear paper-table.

Another feature is the provision of means said sheets are inserted at the front of the machine.

Other features and advantages will hereinafter appear.

In the accompanying drawings,

Figure l is a vertical sectional View showing the mounting of the rear paper-table.

' Figure 5 is an enlargement. of the papertable and gage in Figure 4 showing the detailed structure.

Figure 6 is a plan view of a portion of Figure 5.

Figure? 'is a horizontal section of the paper-table and is designed to show the'relative heights of the flanges on the end gages and the secondary gage.

A cylindrical platen l is supported by means of an axle 2, journaled in end frames 3, of a carriage at supported on a rear rail 5 and a front rail (not shown). The usual pressure rolls Gand paper-apron Tnormally contact with the platen. Co-operating with the platen at the rear thereof is a papertable 10 of much greater length than those used ordinarily. Because of this additional length the table tends to block access to tabufor allowing the free movement of the sheets rearwardly clear of obstructions when .1

lator stops, or, as here shown, column selectors (indicated in Figure 4 by the numeral 11). The paper-table is therefore of a construct-ion which permits it to be swung forwardly to the dotted-line position of Figure 4, thus allowing ready access to the mechanism at the rear of the machine. To this end the paper-table comprises two. parts, indicated in Figures 5 and 6, as 12 and 13. The

lower part 12 has portions of its surface de-,

- The rod thus forms a pivot about which the paper-table maybe swung. The lower part 12 terminates near its sides in forked member" 18 adapted to be attached to the end walls The paper-table. terminates at its upper end in the usual turnedover portion 20.

' Gages 21, 22. are adapted to be slidably mounted on the paper-table at the turnedoveiiportion and for this purpose they are each provided with turned-over portions which extend. beyond the end of the table. They then follow a parallel course for some distance back along the turned-over end of the paper-table. A screw 26 passes through the turned-over ends of the gages beyond the edge of the paper-table. By tightening the screw, the gages may be fastened. to the paper-table without the necessity of passing the fastening means through the table. A

screw 27 aasses throu h the table and age b o r.

and is .merely for the purpose of factory adjustn' ent. It. is not used in the ordinary operation of the machine. I

- In order. that. sheets inserted from the front may pass rearwardly without sin countering obstructions, the lower part 12 of the table has. an elevated portion 30 adapted to lead the sheets over the pivotal connections. The sheets are then taken up on an inclined surface 31 on the upper part 13 of the table. A depression 32 is provided in the upper part of the table in which lodge the down-bent ends of the slidable gages 21, 22, 23, to prevent the sheets from catching thereunder. I I

It can thus be seen that the paper-table 10 can be swung forwardly upon its pivot to allow access to the mechanism at the rear of the machine. However, the normal position of the table is backward, as shown in Figure 4, and, to maintain this position, there is pivoted on each end wall 3 a bracket 34 held b 'stud 35, which when loosened. acts as a pivot. The bracket has a bent end 36 in which operates a stud 37 adapted to engage a slot 38 in the paper-table when The upper part 13' of the.

carried by member 41.

swung to effective position to lock the table in its rearward position. By loosening studs and 37, the bracket may be swung t0 the dotted-line position in Figure 1, allowing the table to be swung forwardly.

At the front of the machine is mounted a collating table substantially as described in said co-pending application 405,013. Said collating table comprises sections 40 and 41 adjustably secured by screws passing through slots 51 to a support 42 carried by brackets 43 fixed to a rod 44in the end walls 3 of the carriage. The heads of screws 50 lie in recesses so as not to project above the surface of the collating table.

It may be necessary to adjust the statement-sheet relatively to the ledger-sheet after their insertion in the machine.

Since the statement-sheet is narrower than the ledger-sheet, means are provided on portion 41 of the collating table outside the range of the statement-sheet for holding the ledger-sheet while the statement-sheet is being shifted; This means consists of a clamp The clamp comprises a presser-block 52 of any suitable material, such as rubber, on an arm of a bent lever 53 fixed on a. shaft 54 carried by a bracket 55 supported on the outside of one of theinen'ibers of the collating table (in thiscase 41). A spring 56 is attached to the collating table and to an arm of the bent lever 53, so that. the spring may act to urge the block 52 towards the collating table, or to urge the same to its retracted position, according as the spring is carried to one side or the other of the axis of the-shaft 54. A. finger-piece 57 may be provided to throw the clamping device into and out of effective position andmay serve to limit the retraction of the clamping device by con.- tacting with the support 42.

The presser-bloc'k 52 holds the wider or ledger-sheet while the narrower or statement sheet is adjusted relatively thereto. When the adjustment is completed, the feed-rolls (3 and the paper-finger 58. may be swung into position to maintain the statement and .ledger-sheets in position on the collating table, and the clamping device is. released. T 1e paper-finger is supported on a pivot 59 on thefront rail of the carriage and held in effective or ineffective position by a leafspring (not shown) engaging a block 60 on which the paper-finger is fixed.

In the operation of the device, it can be seen from Figure 2 that the upstanding flanges of the gages 21 and 23 on the rear paper-table are in alignment withthe upstanding ;ianges of the members 40 and 41 of the front collating table. A sheet inserted from either the front or the rear will thus be guided at both side .edges in the front and in the rear of the platen. In ad dition, another and smaller sheet may be ill) On the members 40 and 4-1.

guided,the smaller sheet being the top sheet at the front of the platen and the bottom sheet at the rear thereof. In the rear, one of the side gages, in this case 21, is used for the alignment of both sheets. A secondary gage 22is provided for the other side edge of the narrow sheet. Since the wider sheet must pass over gage 22 in order to be gaged against member 23, the upstanding flange of gage .22 is constructed lower than the flanges or gages 21 and 23. Figure 7. shows the relative positioning of the flanges and sheets. It is thus apparent that both wide and narrow sheets are each provided at the rear with guiding means at each side edge. At the front, however, the wide sheet. is

guided at each side edge by the upstanding flanges o't' members40 and ll, while the narrower is guided only at one side edge (in this caseby the flange of member 40), relying upon finger 58 for additional means vto maintain the relative positioning of the sheets.

[The member of the front collating table which gages the edges-of both sheets (in this case 40), has its upstanding flange continued beyond the lower edge of the collating table, diminishing in height, until it reaches a position nearly on the line with theuprinting point as shown at 61. This gives the maximum guidance to the sheet, since the latter engages with the elongated flange almost simultaneously with reaching the printing 'point. The usual wing-scales 63 are vmounted adjacent the platen, and have their tips 62 turned slightly upward to enable said scales to ride over the flange It will be seen that the side gages 21 and 23, which maybe called primary gages, form with the rear paper-table 10 a main or primary guiding chute to guide the wider or ledger-sheet, fitting therein, so that, when the .ledger sheet is passed around the platen, "it will lit in the front chute formed by the collating table and the upstanding-flanges Furthermore, it will be seen that the side gage 22 forms with the side gage 21 and the rear papertable a secondary chute, whereby the narrower orstatement sheet will be guided to the front chute, so that theleft edge of the statement-sheet Will lie along the left side of. the front chute when passed around the platen. 7

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