TYPEWRITING, MACHINES Application filed Augustll, 1925. Serial No. 49,511.

This invention relates to collating devices for typewriting machines, which are provided with means for holding work-'sheets "against theplaten at the printing line.

' the provision Many concerns send statements every month, which consist of 'a fewgroups of figures, each group being typed in its parterior width slightly greater than the statement-cards to be used in it. These chutes may be fastened, one at a time, to a crossbar which may be detachably mounted on plates fast on U-shaped brackets slidably mounted on a stiff horizontal rod, the latter being held fast on the usual carriage-frame ends. The chutes are provided with a back wall and a front wall, the latter terminating a short distance above the printing line of the platen. A plurality of downwardly-extending, narrow, flexible curved-fingers may be mounted on said front wall to coincide "with and overlie column-dividing lines of the statement-cards. These fingers are arranged to hold the cards against the platen at the printing line thereof, and guide its leadingd edge between the platen and av paper-table apron. Characters may be typed between the narrow fingers. Work-sheetholding rolls are provided on each side of 'each `chute for holding a record-sheet on the platen. By using cards sutli'ciently stiif that tit their' particular chutes correctly, the

v cards may be quickly inserted and gaged Iby the wing-scales to printing position with one movement, since they require gaging in vertical direction only. No further operation of any cllating mechanism of the machine is requiredunless two o r more lines are to be typed. In such cas e s the platen needs only to be line-spaced vA feature of the invention is the arrangement Aof the lower ends of thenarrow fingers to fit between broad teeth provided in the apron-extension of the usual paper-table, to prevent the cards from catching onthe en d of the apron' when they are pushed down around the platen. Another feature is the provision of simple means for mountingthe card-holding fingers for lateral yadjustment on the chute.

`Other features and advantages will here'- inafter appear.

In the accompanying drawings,

Figure 1 is a fragmentary frontview of the'pre'sent invention, embodied in an Under- Wood typewriting machine, a'nd illustrates how a statement-card appears in thedev'ice.

Figure 2 is a fragmentary cross-sectional view of the device in `Figure 1, and shows certain features of the typewriting machine which were omitted in Figure 1 for the sake of clearness.

Figure 3 is a perspective View of the chute of the present invention, arranged with adjustable work-sheet-holding fingers.

A type 10 held on a type-bar 11 is arranged as usual in an Underwood typewriting machine to be operated by keys, not shown, to strike against aplaten 12 mounted on a shaft 13, which is journaled in carriageframe ends 14. A ratchet-wheel 15' ar"- ranged for rotation, step by step, by the usual finger-piece, not shown, and two fingerwheels 16, one of which is shown, are mounted on shaft 13 for line-spacing the platen 12. Feed-rolls 17 and 17, shown in .both operative and released positions, may be operated by the usual means, not shown. A usual paper-table 18, except for modifications of its front apron-extension 19, as will be hereinafter described, may be arranged in-the rear of platen 12.

A stiff rod 20 is held fast by screws 21 in brackets 22, the latter being fastened by screws 23 to the carriage-frame ends 14., Rolls 24 and 25, arranged for pressing.

against the platen 12, are carried by flexible fingers 26 and 27, respectively, which are fastened by screws 28 to U-shaped brackets 29 .and 30, respectively. The brackets are slidably mounted on rod 20, with a bastv or lateral portion 31a of an L-shaped plate 31 fastened on the bracket 29, between it and the finger 26. A similar L-shaped plate 32 is fastened on a U-shaped bracket 34 adjacent the left end of the platen 12. The.` right end of a stiE bar 35, having a rectan-4 gular cross-section,'may be fastened by a. screw 36 to plate 31, and the left end of the.

bar, which is arranged with an open-end L-shaped slot 37, may be fastened by a screw 38 to plate 32, the slot 37 permitting the To hold the brackets 29 and 34 against undesired lateral or'rotary movement on ro'd 20, hubs 45, provided with screws 46, may be soldered to the outer and shorter arms of the brackets. Bracket 30 may have a flat s ring30 arranged to engage a groove, not s own, in the under side of the rod 20,

.to hold the bracket against rotary movement around the rod While permitting easy lateral adjustment thereon.

A chute 50, positioned labove the platen i 12, between the rolls 24 and 25, which may have converging and rearwardly-inclined .front and back walls 51 and 52, respectively,

is fastened on the bar 35 by screws 53, set in countersinks 54 of the back wall 52, so that the screw-heads do not project above the front side of the back wall. The chute may have ends made by riveting or sol. dering together flanges 57, 58 and flanges 59, 60 of the front and back walls, respectively.

To'use the collating devicea record-sheet 61, with an overlying narrower carbon-sheet 62, may be inserted around 'the platen 12 from the rear in the usual wa ,being passed under the rolls 24 and 25, andyi chute 50, and properly gaged by means of the usual wing-scales 72, whose top edges `7 3 may rest against the convex surfaces of the fingers 66. The feed-rolls 17 and 17a may now be cast oi, and a statementv sheet or card 63, havin ruled columns 64 with vertical dividing ines 65 and appropriate headings or designations for the columns, may be inserted in the top of the chute 50. To facilitate insertingand withdrawing the;` statement-card 63, the front and back walls 51 j and 52 may have central top portions 51 and 52", respectively, removed. The lower edge of the frontwall may be arranged approximately tangent to the platen, just above the printing line. To hold the statement card 63 closely against the record and carbon sheets 61 and 62 on the platen 12, a plurality of curved flexible lingers 66 are rovided which have a wide portion 67 for astening' them along ythe, lower edge of the front wall 51 by riveting or soldering. The lower portions 68 of the lingers 66 will preferably be very narrow and no thicker than necessary to give sulicient strength for holding the statement-card 63 closely against the platen- 12, since they eXtend\ down below the rinting line and must clear the usual ri bonvibrator, not shown. The pressure of the fingers 66 and rolls 24'. and 25 against the platen 12 can be varied by a small rotation of rod 20.

The statement-card 63 will preferably be printed on paper or cardboard slightly narrower than Vthe inside width of the chute 50,

vand will be suiciently stift' to allow it to lp-behind the with, so that the statement-card 63 catching on the top edge 69 of the apron 19 when the card is being inserted, the apron may have vshallow, teeth -70 arranged so that the lower ends of the narrow linger-portions 68 may rest against the platen 12 in notches 71 betweenk the teeth 70. Thus the loweredge' of a card will be past the top end of apron 19 before it is out from under the pressure of the fingers L When the leading edge ofthe statement' card 63 has been pushed down past the printing line and the card has been gaged to printing position by the wing-scales 72, one line of dat-a may be typed at once. To type two or more lines, the platen l2 may be linespaced by one of the finger-wheels 16, or by throwing on the feed-rolls and operating the usual line-spacing finger-piece, not shown.

When all the desired data has been typed on a statement-card 63, the feed-rolls 17 and 17a will be cast olf, and the card 63 can be easilypulled from thetop of the chute with' out changing the position of the record-sheet 61, which is securely held by the pressure of the rolls 24 and25.

To remove the chute 50 and replace it with J one of a different widththe screw 36 may be removed and the screw 38 released. and

the bar 35 carrying the chute 50 may then be removed. The screw 46 may next be r0- leased, and the bracket 29 carrying plate 31 may be moved to the new position and the vscrew tightened. The bar 35 carrying a different width chute may now be fastened on theplates 31 and 32. It can be readily seen that the collator can be easily and quickly removed from the typewriting machine by unscrewing the screws 21 and removing the collator upwardly. l

In Figure 3 is illustrated how the cardholding fingers 166 may be arranged for lateral adjustment along the chute 50. A rectangular rod 175 may be fastened by lscrews 176 to iaps 177 integral with t-he front wall 51 and bentaround in front of said Wall. Each finger 166 may have a flattened portion 167 fastened by soldering or welding to a split rectangular ring 169 ar- Y ranged for a sliding fit on the rod 175, and each ring may have a screw 170 for holding it in position on the rod.
