TYPEWRITING MACHINE.

Application filed. January 28, 1925. Serial No. 5,261.

This invention relates to clips for positioning work-sheets in typewriting machines, and one of its features is the provision of means for holding a card in front of the platen of the machine upon which it is de sired to type a line of data.

Another feature is the provision of means whereby the line of typing upon the face of the card is recorded upon a copy-sheet around the platen.

Another feature relates to the design of the clips, and to the means of attaching the same to an Underwood standard machine. The clips may be readily slipped onto or off the machine, which requires no alteration thereof, and are made interchangeable to fit the existing machines.

A copy-sheet having a superimposed narrower sheet of carbon-paper is inserted in the machine down a rear table at the introductory side of the platen and under the platen engaging co-operating feed-rolls and up infront of the platen. A card upon which it is desired to type a line is then inserted bottom edge first in front of the platen, between the platen and the clips, and down to a locating stop below the printing line. 'The clips, which are made of resilient material, are sprung onto the feed-roll shaft, and are bent inwardly against the platen to render them effective to firmly hold the card against the platen in a flat condition.

I A line of typing is then written upon the card and is consequently copied on the copysheet. The card is removed by gripping the leadingedge with the fingers and the copysheet is line-spaced, so that, when a fresh cardis inserted again in the machine, the line typed upon the card will be recorded on the copy sheet as a record line of typing thereon. It will be noted that the worksheet, as it is designed and shown in the drawings, consists of a card upon which it is desired to type a line of data pertaining to the monthly billing of a gas company. In such cases it is customary to fill in the name and address on the card by mechanical means previous to inserting the card in the typewriting machine. It is also customary for the gas company to send their customers bills having detachable stubs which each customer returns when making payment, to identify the transaction. While it is conyenient to type the total amount of the bill upon the stub, it is not desirable to have it written twice upon the copy-sheet. To this end, the sheet of carbon-paper is narrower than the card, so that the total amount typed on the stub will not be transferred or copied upon the copy-sheet.

t is sometimes desired to type two lines upon the card, and, although no special mechanism is provided for so doing, the method will be briefly stated. The card is held firmly against the platen with one hand, while the platen is spaced one line either by means of the finger-wheel or the regular line-spacing mechanism; thus the card, the copy-sheet and the carbon-paper thereinbetween are simultaneously line-spaced.

Other features and advantages will hereinafter appear. i

In the accompanying drawings,

- Figure 1 is a front view in elevation of part of an Underwood typewriting machine showing the platen, the feed-rolls and the clips attached thereto. It also illustrates the relative position of the card, the carbonpaper and the copy-sheet.

Figure 2 is a cross-sectional view in elevation through the line 2-2 of Figure 1, and shows the position of the clipsin relation to the platen when holding the upstanding card in front thereof.

Figure 3 is a side view in elevation of one of the clips, and shows the clip both in its normal or released position and when sprung on the machine under tension.

Figure 4; is a perspective view of one of the clips. 7

Figure 5 shows one of the forms or cards thatmay be used in connection with this device.

A copy-sheet 10 having a superimposed carbon-sheet 11 is inserted, leading edge first, down a rear table 12 and under a platen 13 co-operating with feed-rolls 14 and 15 and up in front of said platen. The feed-rolls 11 and 15 are operatively mounted on a shaft 16 connecting the two platen frames 17 and 18 upon which the platen is journaled by means of the axle 19 which also carries, fast thereon, the finger-wheel 20 and the line-spacing gear 21.

A card 22, upon which it is desired to type a line of data, such as is indicated by the numeral 23, may be placed at the front of the platen in a position to be struck by a type-bar 24. The card is inserted bottom edge first between the platen andcllps 25, and is'lowereddown to astop 26. 7

Then, a line is typed upon the card and the card is withdrawn and another fresh cardinserted, and so on. After typing each cardythe copy-sheet and the carbon-sheet are simultaneously line-spaced .around the platen, either by operating the finger-wheel 20' or the regular line-spacing mechan sm (not shown) to expose an unused portion of the sheets.

Oneof the features ofthis invention 1s thatthe clips may be readily slipped onto andzoff from the machine, and to thisend theclips are provided with a supporting or lower member having a loop 27,, partly open,1so that it may be sprung over the feed-roll shaft 28 and slid thereon for lateral adjustment. From the loop, downwardly and'forming an integral: part thereof, there isnprovided .a. fork-like extension 29 whlch terminatesin two prongs 3O bearing upon a shaft 31, which normally is used to release the feed-rolls by meansof a link 32 operating upon a crank 33. Upwardly extending fromthe'lower member .and fast thereto, :there is provided a resilient .metal strip 34 which is normally held under tension against the platen holding the card 22 'thereinbetween. .Said strip 34 is shown in the drawings solderedat 85 to the loop 27, but itis obvious that the two membersmay bexmadeout ofone piece without depart- -in fromthe spirit of the invention.

Iieferring more particularly to Figure 3, it will be noted that the clips are inwardly bent when off the machine, as shown in full lines in said Figure 3, while when placed in the machine the clips. are under tension between the shaft 31 and the platen, as indicatedin dot-and-dash lines.

The cardissquared by forcing its lower edge 36 against the loop' 27, which forms a locating stop for the card. Due to the factthat the clips are notaadjustable and the stop formed by the loop 27 is at axfixed position relatively tothe printing ilineon the platen, .the card 22 must consequently be designed to be adaptable to this condition,-so. that the line of typing will be-av distance from the bottom edge 36 equal to the distance between the loop 27 and the printing lineon the, platen.

Referring to Figure. 1, itwill be noted 7 that the carbon-sheet interposing-vthe card and the copy-sheet underlies the cardonly and-notthe stub. 37 which is separable from thecard at the perforated line 38. The carbon-sheetextends from the left-hand edge of the copy-sheet tothe line. 88, so:that the totalv39ion thestub 37 may be typed thereon but not transferred to the copy-sheet, upon which-it is desired to copy one total only indicated by the numeral 40 Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.

Having thus described my invention, I claim:

The combination, in atypewriting 'machine having a revoluble' platen, ofupstanding paper-fingers attenuated to about the width of a letter-space and placed between the printed columns of a work-piece to hold the work-piece between its ends against the platen, and means below the printing line supporting said-:paper-fingers by their-bottom ends, said papenfingers having means effective to positionsaid work-piece inline space. direction.
