UNITED STATES J'I'BSE A. B. SMITH, OF STAMFORD, CONNECTICUT, ASSIGNOR TO UNDEBWOOD TYPE- PATENT OFFICE.

WRITER COMPANY, OF NEW YORK, N. Y., A CORPORATION OF DELAWARE mnwnrrmo mcnmn Application filed December 24, 1920. Serial No. 432,906.

To all whom it may concem:

Be it known thatl, 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 collating and feeding means for typewriters.

More particularly, it relates to billing machines, in which are typed, at one time, several sheets, such as a worksheet or tall strip, bill-sheet, and ledger-sheet, said bill and ledger 'sheets being separately gaged laterally (because of their varying widths) and also longitudinally, to permit entries that are made at intervals to be accurately aligned and spaced one under another upon the bill, ledger and record sheets.

The present' invention is generally similar in purpose to the invention disclosed in my application No. 404,882, filed August 20, 1920 (now Patent No. 1,487,671, of March 18, 1924). A wide ledger-sheet may be ged by passing it down over a rear paper table, provided with side-edge gages, and bringing it up in front of the platen, so that its upper end lies upon a front papertable, provided with side members, against which the ledger-sheet is gaged laterally. Two sets of auxiliary and co-operating feed-rolls or collating-rolls are provided at the front. table, said ledger-sheet being clamped between said collating-rolls by the actuation of a finger-piece after being adjusted laterally on the front paper-table. These collating-rolls lie outside of the mar gins of the narrower bill-sheet, upon which most of the original entries are made. The bill-sheet is then passed down and gaged laterally by a chute which may be formed in the rear paper-table,- to carry the narrower sheet clear of the first inserted sheet, and guided upwardly between side gages provided upon an auxiliary front papertable which stands clear of the main front paper-table, for the wider sheet, but which is fixed to the side members of said main front table. A record-sheet may be fed around the laten to the rear of the ledgersheet and t e auxiliary rolls, and. beneaththe front tables. The record-sheet may be a tally-strip, and may be held in position on the platen by a suitable tally-strip device.

The auxiliary front paper-table, adjacent one'of the side gages for the bill-sheet, is provided with a sheet-gripping clamp which can be operated to hold said sheet in adjusted position while the work-sheet or ledger-sheet is adjusted, by means of the collating rolls.

The shaft of one set of auxiliary feedrolls is provided with a finger adapted to rest adjacent the flat surface of the auxiliary front paper-table, said finger lying beneath said clamp, so that, when the auxiliary rolls are cast off to release the ledgersheet, the clamp will also be rendered ineffective in order tolrelease the bill-sheet.

When all the sheets have been adjusted laterally and longitudinally with respect to each other, the usual pressure-roll releasehandle is operated to clamp all the worksheets against the platen, preferably before the collating-rolls and the clamp have been released. While the usual feed-rolls are released, and while the ledger-sheet and the bill-sheet are held, respectively, by the collating-rolls and by the clamp, if desired, yet another work-sheet may be inserted and gagged, as an outer sheet. There may be provided an upwardlyextending finger pivotally attached to the frame of the carriage and adapted to rest at the front of the aux iliary front collating-table to engage the sheets at a point intermediate their side edges. There may be provided also an addi-' tional wing-scale to aid in sheets inserted into the machine when the platen is near one end of its travel before being brought back for the beginning of a new line of typing.

Other features and advantages'will hereinafter appear.

In the accompanying Figure 1 is a perspective view of an Underwood machine, with the invention applied thereto, only such parts of the machine as co-operate with the invention being shown.

Figure 2 is a top view of the front collating-tables and the side gages attached thti reto. d 11 h bl igure 3 is a eta' s owing a suite e mounting for the sheet-collating rolls.

shown as a tally-strip 12(i Figure 4 is a vertical section of the device shown in Figure 1, the collating-rolls and the clamp on the auxiliary collating-table being shown in full lines in their effective positions and in broken lines in their in effective positions;

A bill-sheet 10 and a ledger-sheet 11 are adapted to be passed downwardly over a rear paper-table 13, around the platen 15, mounted upon axle 16, journaled in the end walls 17 of the platen-frame of the, usual carriage. A record-sheet, which is here is fed from feedroll 20 of a tally-strip evice- 21, mounted on the end walls 17 of the carriage, said strip passing around the platen to a winding roll 22.

The ledger-sheet 11 is' fed over the rear paper-table between adjustable side gages 25, movable alon rod 26, fixed on brackets on the rear of t e paper-table. The narrower bill-sheet is adapted to be fed over the paper-table in a depression or chute 30, forming side-edge gages therefor, said chute merging with the extension 31 of the papertable, forming the usual paper-apron.

Front and rear pressure-rolls or feed-rolls 32 and 33 are adapted to press the sheets against the platen.

Passing around the platen, the ledger and bill-sheets are carried upwardly in front of the platen, where the ledger-sheet 11 is adapted to be adjusted upon a front collating-table 35. It is understood that until all the work-sheets are adjusted relatively to each other, the pressure-rolls 32 and 33 remain cast off the platen.

As shown in Figure 1, the collating-table 35 is composed of two sections carried by supports 36 suitably mounted on the end plates 17 of the carriage-frame. The collating-table 35 is provided with side edge gages 37 which co-operate with the side edge gpges 25 to guide the ledger-sheet 11 at the out and rear. The collating-table is also provided with openings 40, into which project collating-rollers 41 from the rear, and co-operating with said rollers are collating-rollers 42 at the front of the collatingtable. Rollers 41 and 42 are mounted upon shafts 43 and 44, respectively, shaft 43 being journaled in the end walls of the carriage and having a knob 45 at its outer end for turning said shaft, in order thereby to adjust the 'ledger-sheet 11 relatively to the printing line on the platen. Shaft 44 and rollers 42 may be swung forwardly to move the rollers 42 out of contact with rollers 41, because said shaft is fixed to rock-arms 46, which are fixed to short'shafts 47 'ournaled in brackets 50 on each end wall 1 Shaft 44 has an extension 51, upon which is fixed a finger-piece 52. By swinging finger-piece 52 forwardly, rollers 42 are swung away from rollers 41, and by swinging said finger-piece rearwardly, rollers 42 are brought into gripping relation with rollers 41. The shafts 47, journaled in brackets 50, normally tend to press feed-rollers 42 rearwardly, because said shafts are each provided with a cam having a depression in each of which normally seats a projection on a spring-pressed follower 53, pivoted at 54 on each bracket. When the pressurerollers 32 and 33 are cast off and the collating-rolls 41 and 42 are in engaging relation, rotation of knob 45 will feed a sheet upwardly, or downwardly, to any desired extent. In this way the sheet gripped by the collating-rolls 41 and 42 may be adjusted to any desired position relatively to the printing line on the platen The ledger-sheet, being gaged and guided by said edge gages 25 and 37, passes between rollers 41 and 42, which are rotated by means of knob 45 to properlg position the ledger-sheet longitudinally. ill-sheet 10 is passed around the platen outside the ledgersheet by passing it into the depression or chute 30. The bill-sheet is guided by extension 31 to the front of the platen and is led in front of the ledger-sheet 11 to an auxiliary table 56, carrying auxiliary side edge gages 57 thereon, and shown as formed. in two sections. The table 56, as shown in Figures 1 and 2,'has downturned flanges 58, which are fixed to the side gages 37 of the main collating-table. vided a space 60 between the main and auxiliary collating-tables, through which passes the ledger-sheet. The bill-sheet passes over the auxiliary collating-table 56 and is gaged at the front by side edge gages 57 and at the rear by the side walls of chute 30.

While pressure-rolls 32 and 33 are, cast off, the ledger-sheet is held in position by rollers 41 and 42. The bill-sheet is held by a clamp pivoted on one of the sections of the collating-table 56 and adapted to be swung over a side gage 57 against the billsheet. The clamp consists of a member 61, pivoted at 62 to a bracket 63, fixed to the table 56. The member 61 has a bent portion 64 adapted to avoid contact with the side gage 57, and has a rubber band 65 at its end adapted to press the bill-sheet against table 56. A spring 66 is fixed to the bracket 63 and a pin 67 on member 61 in such manner as to urge the member toward or away from the table 56, according as the There is thus prospring is to the rear or to the front of the and 11, the ledger-sheet 11 may be held in adjusted position by the collating-rolls 41 and 42, while the bill-sheet 10 is adjusted, or

the bill-sheet 10 may be adjusted first and may then be held in adjusted position by the sheet-gripping clamp 61, while the ledger-sheet 11 is adjusted or collated by is at mechanism may be of the means of the collating-rolls 41 and'42. Th'e ollating-rolls 41 and 42 are particularly adapted for use in adjusting a work-sheet which is overlaid in the machine by another work-sheet, in which case the overlying work-sheet prevents free access to the underlying sheet which is to be adjusted, such, for example, as the le -sheet 11 which is overlaid by the bill-s eet 10. Also the collating-rolls 41 and 42 enable convenient adjustment of a work-sheet should ready access to the sheet at the front of the machine be interfered with by parts of the machine, such, for example, as the auxiliary eollating table 36, behind which the ledgersheet 11 passes. When all the sheets have been adjusted the pressure-rolls 32 and 33 are then thrown on, and ledger, bill, and record-sheets typed simultaneously. An additional wing-scale is provided, mounted in the usual manner, and designed to aid in adjusting the sheets easily when the carria e one end of its travel. The tally-strl same genera form as described in the patent to Hart, No. 1,2,81,160,-dated October 8, 1918. v

In order to facilitate line-feeding of the bill-sheet 10 and the ledger-sheet 11 during the typing operation, the clamp 61 and the collating-rolls 41 and 42 may be released. Also the clamp and the collating-rolls should be released when a bill has been typed and the ledger and bill-sheetsam to be with-.

drawn from the machine. It is desirable to provide mechanism for simultaneously releasing the clamp holding the bill-sheet and separating the auxiliary rolls 41 and 42 holding the ledger-sheet. This means comprises a finger 71, fixed to shaft 44 and projecting upwardly until it is capable of resting just at the front of the in broken lines in Figure 4. Member 61 of the clamp is provided with an extension 72, beneath which finger 71-is adapted to lie when the clamp and the collating-auxiliary devices carried by table section 56, upon which the bill-sheet is held, as shown J devices carried spring 77 engaging a block 78 on which the] finger 1s fixed, and is adapted to direct the sheets against the front of the auxiliary collating table at a point intermediate the side edges of the sheets.

In the machine of the present invention if for any reason it should be found desirable to type another work-sheet in addition to the bill-sheet 10, ledger-sheet .11 and tallystrip 12, or corresponding sheets, such additional sheet may be inserted as an outer' sheet and may be gaged and adjusted over the auxiliary front collatin table 56 while the other sheets in the mac e are held in position b' the means hereinbefore described. owever, in view of the particular construction of the clamp-releasing means shown in the drawings, such additional sheet should be sufficiently narrow to escape the clamp-releasing finger 71 at the left margin of the sheet. Of course, if desired, a plurality of work-sheets may be superimposed and all adjusted together, and may be all held in adjusted position by the clamp 61. Y

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