To all whom it may concern:

Be it known that I, FRANK A. RoB Nson, a citizen of the United States, resid ng in Brooklyn borough, city and State of New York, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification. t

This invention relates to typewrlting'machines provided with. means to enable a number of work-pieces towbe quickly arranged on the platen, particularly where the workpieces are of difi'erent widths and arranged with their leading edges at different positions of advancement, as is common, for in making entries on statements, bills, or the like, arranged on the platen together with a loose-leaf ledger sheet, or

' other record sheet. I

' any one of a series space distance inxadvance of the preceding sheet placed on'the' ma This invention is an improvement on the invention disclosed in the co-pending application, Serial No. 89,303. Said application shows a paper chute or guide at the introductory side of the platen, on which the work-pieces may be placed, and advanced bring their leadin ing board exten front face of the platen.

The present invention provides improved means to assist in quickly and accurately adjusting lating board and then holding them against accidental displacement. For this purpose there is provided a sheet-ho1ding and gaging dev ce' or prise a graduated series Ofsheet-holding bosses orstuds arranged in a row at the collating board, and adapted to enter correspondmgly positioned openings provided in the margins of the work-sheets. Said bosses .may be arranged atline-space intervals, so

that a work-sheetmay beheld thereb at of positions, each a ine- Thus a position.

adjusted thereon and held by a row or rows of; saidstuds entering corresponding openings in the margin or'rnargins of the sheets. The sheet may beheld in position by onehand of the operator, while with. the

other hand the overlying sheet, which may beof less width, is adjusted over the first sheet. A plurality of *thewgaging bosses hold. the overlying sheet square. with the platen and in register; with the firstshcet, thus overcoming the usu'aldifliculty of alining the overlying sheet and-holding it from shifting until the sheets are clamped to the platen.

Other features and advantages will. hereinafter appear.

In the accompanying drawings I Figural-is a front perspective, v1ew ,fshowing a paper carriage of an Underwood typewriting machine, with the-present invention applied thereto.. a Fig.2 is-a part sectionalend elevation of Fig. is a front, elevation show-ing; the method of adjusting the work on the machine. Fig. 4 is a sectional end. elevation,=showing the work-in adjusted position. i b Fig. 5 is a fragmentary view. of gage ar. The roller-platen l0, has-its: axle 11 journaledin a platen. frame 12,, said frame mounted for case-shifting movement-on the carriage frame '13; "The platen mayybe ro tated by hand wheels 14 on the platen-axle, or by means of the usual line-spacing mechanism, comprising a. line-space ratchet wheel 15' fixed to the "platen axleaand driven step the platen to print on the work-sheets. Feed rolls 19 bear against the platen and-cooperate therewith to advance the worksheets when the platen is rotated. The feed rolls may be thrown off the platen by. means of a key 20 connected through a link 21 to a rock arm 22 on a rock shaft 23. The latter is provided with flats 24, which when the key 20 is depressed, operate levers compris ing arms 27 and 25. The arms 25 carry a shaft 26, on which the feed rolls are mounted. When the shaft 23 is rocked, the arms 27 are movedrearwardly by the flats 24,.to

move the feed rolls ofi the platen.

The means for positioning the worksheets on the platen will now be described. Such means comprises a paper chute or guide 30 at the introductory side of the platen. Said chute has at its lower end an exte'nsibrrBl curved around the platen, and spaced therefrom to provide a passage-way for the work-sheets, so that when a sheet is placed on the chute it may be pushed for- .ward and guided around the lower surface of the platen, and upwardly astthe printin line, to bring its leading e dge on a sheetco lating table 32. The chute 30 is provided with end flanges 33 for gagin the lateral edges of the work-pieces, t e' collating board 32 also being provided with sheet-.

gaging end flanges 34, which'are preferably in alinementwith the gages 33. The chute 30 may be supported by a bar 35, extending between the platen frame ends and forming part of the. platen frame; The chute may be further, supported by a tie rod 36 of the platen frame, which rod extends through openings in the flanges 33.

The sheet-collating board or table 32 may be supported by brackets 37 mounted on the rod 36, to which brackets is secured a bar 38 extending lengthwise of the platenandconnected by screws 39 to the collating board. The bar 38 may be slotted to receive the screws 39, permitting the board to be adjusted. toward or from the platen. The collating board is formed with sheet-supporting surfaces 40 at its-ends, which surfaces are offset or raised with respect to the central orbody portion 41 of the board. The surfaces 40 are also extended upwardly a substantial distance beyond the central portion of the board, to provide ample sup ort for the work,- and to facilitate the ad ustment of the work on said board. The construction thus far described may be substantially like that disclosed in the co-pending application 89,303, above referred to.

The means for gaging the work-sheets and holding them inadjusted position comprises gaging bars 42, mounted on the sur- 43 to enter a series of circular openings formed in the margin of the work-sheet. The roundedshape of the bosses facilitates the quick adjustment of the sheets thereon, and also permits the sheets to be readil disengaged, thatis, the bosses are self-freeing from the sheets.- The rows of bosses are parallel with the ages 34, and may be equally spaced, pre erably at line-space intervals determined by the spacing of the teeth of the line-space ratchet wheel. There is thus provided a graduated series of sheetgaging and holding bosses by which a worksheet may be gaged and held by a number of'said bosses, with its leading edge at any one of. a number of difierent positions of advancement beyond the printing line, and while the sheet is retained by the feeding rolls 19; the sheet being then released from said bosses while it is still retained by the feed rolls. As the sheet, in each adjusted osition, is held by. a number of bosses, it is thereby squared tothe printing line on the platen. Each position of adjustment isalso an exact line-space distance in advance of the preceding position, which arrangement is of particular value in securing uniform spacing of the typewritten lines on asheet which is placed. on the machine a ,n-umber of times, each at a different linespace position. Each gage bar 42 is adjustable toward and from the printing line, and to permit such adjustment, is rovided with a screw-threaded stem 44 ig. 5) which extends through a-slot 45 in the collating board to receive a thumb nut 46 behind the board. The gage bar is also provided with a lug 47 projecting downwardly through a slot 48in the board for guiding the lower end of the bar. By loosening the thumb nut 46, the gage may be adjusted toward and from the platen, and then clamped in adjusted position by screwing up the nut. With this construction, the gage or ga es may be adjusted to anyhorizontally-ru ed sheet or printed form, provided with perforations to receive the bosses 43. That is to say, the gage may be adjusted so that when a sheet is gag'ed thereon,a ruled line or a blank space designed to receive typewritten matter, will register with the printing'line on the platen.

Fig. 3 illustrates'a method of arranging Work on the machine. As here shown, the work comprises a loose-leaf ledger sheet 49 and a statement sheet 50, such as are employed, for example, in a system of bookeeplng where monthly statements may be made of an individual account, each statement comprising various items entered on different days of the month. The statement 1s placed on the machine, with a ledger sheet. containing the record'of said account, each,

is made, and at a difierent position, and also that the sheets are not always adjusted to a the same relative position, so that proper positions,

receive the first line of writing,

justment of the sheets,

it is important to provide means enabling the sheets to be quickly adjusted individually to their and also to provide for bringing the sheets into accurate register. The present invention provides such means. The ledger sheet is first placed on the machine as above noted, and moved upward over the collating board 32 into position to thereby bringing openings 52 along the side margins of the sheet over the studs 43, so that the studs may project into said openings, Whereby the sheet is accurately and definitely positioned on the board. The sheet may be held on the studs by one thumb or finger of the operator, while the other sheet 50 is placed on the chute 30 behind the sheet/a9, and advanced to the Fig. 3 position, where a number of openings 52 in its margin, engage studs 43.

The'gaging and insure refinement of adjustment by accurately and'definitely determining the positions of the sheets. Theyalso hold the sheets against sliding on the work table or being "shifted out of ad-,

justment. After the sheets are adjusted, the

feed rolls 19, which during the arrangement of the sheets are held ofi' the platen, are returned to the platen, and hold the sheets in adjusted position. The sheets being released from the hand of the operator, will spring away from the studs, which, owing to their rounded or tapering form, are self-freeing. This clearing of the sheet from the studs is also aided by the advance of the sheet at the line-spacing operation, since the sheet above the platen and below the racks will tend to bulge out and hence to withdraw from the bosses, if any of them should still engage the sheet.

The led er and statement sheets, as shown inFig. 3, iave similar rulings and headings,

. each sheet having columns for debits, credits,

balance, old balance, etc., and are designed for use on a combined typewriting and'cornputing machine, comprising mechanism for mechanically effecting computations as the items are written. To clearly set forth the method of using the present invention, the method of entering the items shown on the mechanism.

studs 43 assist in the final adledger ing understood that the statement sheets on which-these items were simultaneously entered, are not shown on the drawing.

The ledger sheet having been placed on the machine, and a statement sheet (not shown), arranged thereover, a star 53 is printed in the right-hand side of a column 54; provided for that purpose. This indicates that the computing mechanism has been cleared, readyfor a new computation. The previous balance of $3.00", as shown at 55 (copied-from the old ledger sheet), is then printed in the old balance column, this number being automatically placed on the computing mechanism as it is printed. The platen is now line-spaced and moved to the right to receive an entry on the statement sheet and ledger sheet, includin date, terms,

-etc., and an amount of $4.00 written at 56 in the debit column, said amount as it is written bein -run up on the computing he balance of $7.00 shown by the computin mechanism is now written in the' balance column, the computing mechanism cleared, and a star 57 printed in the left-hand side of the column 54, thereby showing that the correct balance'has been written and the machine cleared for another computing operation. Thework ma then beremoved from the machine and filed away until it is desired to make another entry,

'when'the above order. of operations is re peated.

Assuming now cated on the sheet 49 have been made, and that it is desired to make a new. entry, the ledger sheet 49 is first-placed on the ma chine and advanced until the last'typewritten line, which in the example shown includes the star 58, appears above the wings or gage plates 59, the upper edges of which "extend along the printing line, wfhe sheet may now be pressed against the work table bv the finger of the operator, so that the bosses 43 enter the perforations in the sheet, thereby squaring it to the platen and holding it in the exact line-space position thatit occupied when receiving the preceding entry." The statement sheet 50 is now adjusted over the ledger sheet, so that the last typewritten line of the statement (which in the example illustrated is a balance of -$3.00, shown at 60) is brought to the linegage plates 59; the statement sheet being quickly and accurately gaged by the bosses 43. The work is now in adjustment for receiving a new entry, which may be made by repeating and underlies the latter, in practice this order is frequently reversed, the ledger sheet being madenarrower than, and placed over the underlying statement or'bill.

sheet 49 will first be explained, it be- "that all the entries indi-Tr Variationsmay be resorted to within the scope of the invention, and portions of the improvements may be used without others.
