To all whom .z't may concern;

Be it known that l, J nssn A. B. SMITH, a citizen of the United States, residin in Brooklyn borough, in the county of Kings city and State of New York, have invente certain new and useful Improvements in Type-"Writing Machines,'of which the following is a specification.

This'invention relates principally to type-- writing machines, and more especially to machines of the general character shown in the patent to \Vernery & Smith, No. 1,132,- 055. Such machine is adapted for writing on a number of superposed continuous sheets, especially on webs folded longitudito have written lengths or sectionsthereof to be torn ofl' in cross section from the body of the web, as for example, when the web comprises a series of printed forms. In such workit is usual to employ'ink-ribbons or carbon sheets interleaved with plies of the webs for making duplicate copies. After a section of we has been written, the platen is shifted away from the usual feed-rollers to release the web and the interleaved carbon sheets, whereupon, by means of a carrier or holder the carbon sheets are drawn back along the web preparatory to printing on the succeedof the web. The same carbon sheets are thus used repeatedly with the same web; The carbon-sheet-holder of a machine of this character is usually su orted on' a carriage which rides'on' a trac provided on a frame or table attached to the platen carriage. The table and carbon sheet-holder therefore partake oi the letterfeed and return movements ofthe platen carriage, while the carbon-sheet holder has also its own line-spacing and return movements on the table, but toward and away from the platen. The holder for the carbon sheets ordinarily comprises 'a set of fingers or clips to each of which the rear edge of a carbon sheet is secured. These fingers pro trude into the oppositely-directed folds of the web from opposite sides of the carriage, and are preferably stepped one above the other to permit of movement of transfer material, without binding, when the same is shifted backwardly along the web. Hereina fter appear.

folds of the web, so as not to catch upon or tear the web.

It is sometimes desirable that the plies of the web, or at least some of the plies, he severed from one another in the machine, so that when a written length or section of web is removed, the plies thereof are already separated for distribution. h

It is an object of the invention to efiect such a separation of the plies of the web; and it is a further object of the invention to utilize the fingers, which hold the carbon sheets, as the means by which the separation is effected. For this purpose, in the referred form'of the invention, the fingers, instead of terminating inside of the lines of the folds of the web, are extended across those lines, and are shaped at their ends to form paper cutters. Commonly, to permit of easy separation of the plies of the web along correct lines, the web, as fed into the machine, is perforated along the lines of its folds. When the web is thus perforated, thecutters of the present invention may be blunt paper-splitting devices. Thesevering of the plies by the are moved backwardly along the web by sheets for the writing of a new section of the web. The cutting edges are therefore preferably inclined backwardly and inwardly across the lines of the folds. As it may not be desired to separate all of the plies, certain only of the fingers which hold the carbon sheets need carry cuttefs.

Other features and advantages will here In the accompanying drawings, Eigure 1 is a perspective view of aconstruction emhodying the invention as appliedto an Underwood typewriting machine, the parts being in position to permit writing upon a work-piece." Fig. Qis -a fragmentary perspective view of one of the clips or fingers for holding a sheet of transfer material, the web-cutter or separator of the present invention being shown on thefend of the clip. Fig. 3' is a view in cross-section through the fingers which hold the carbon sheets takes place when the fingers t ot'ore the holding fin ers have terminated at'the1r free ends insi e of the lines of the web, showing the manner in which it is folded, and showing one of the clips in position to out the'edges of the web at one of the folds-thereof. F ig. 4 is a plan view of a fragment of the web; the cutting blades being also shown in position for cutting.

Referring particularly to F ig. 1, which Shows the general arrangement of the platen carriage, carbon-sheet-holder, and means for unfolding or straightening the web to permit the carbon sheets to be retracted; the platen is fixed to a platen shaft 11 journaled in arms 14 and 15 of a frame'fast to a rock shaft 12. The shaft 12 has hearings in the ends 13 of the usual platen frame.

. The swinging frame is normally held in the Fig. 1 position for writing, with the platen down against the usual front feed-rolls (not shown), and may be swimg from this position to its web-releasing position by means of an arm 16 fast to the rock shaft. 12, and provided with a handle 16. For locking the swinging frame in the. Fig. 1 position,

the arm 16 carries a pin 17 adapted to, be enga ed by a hook 18 pivotally mounted on the p aten frame end 13. A spring 19 yieldingly holds the hook in operative position, and in returning the parts to such position,

the pin 17 cams back the hook so that the locking may be automatic. A tooth 200;) the hook, together with a pin 22 on the righthand end 13 of the platen frame, determines the return throw and normal position of the swinging frame.

The platen may berotated by the usual hand wheel 24, or the line-space ratchet wheel 25,both fast to a short shaft 26 mounted to rotate in the left-hand end 13 of the platen frame. When the platen is in printmg position the shaft 26 is in alinement with the shaft 11. As is common in Underwood typewriting machines, the ratchet wheel is actuated by a pawl 27 on the usual slide 29 engaged by one arm of a line-space lever (not shown), on the carriage frame. A spring-actu ated detent engages the ratchet wheel to hold the platen against rotary displacement. The driving connection between the shaft 26, whose axis is stationary, and the platen shaft 11, which swings upwardly from normal position, consists of gears 35., 36 and 37. The gear 35 is fast on the shaft 20, the gear 36 is fast on the platen shaft, and of the same diameter and provided with the same number of gear teeth as the gear 35, and the gear 37 is looseon the axle 12, nrnllnd which the platen swings as an axis, the gear 37 having a face of sufficient width to mesh with both gears 35 and 36. The driving connection between the shaft 26 and the platen is thus maintained in all positions of the platen.

in. the operation of removing a printed l'ength from the wehs and 111 read ustmg the are preferably perforated to permit of easy detachment of one ply from another.

The webs may be fed into the machine over the rear rail 38 of a table 39, the side rails 40 of which are further connected and braced by cross bars 41 and 42, and, at the The webs are formed.

front of the machine, by a rod 43 journaled in bracket arms 44 in the platen carriage, so that the table may be folded up when desired. The table is secured to the platen carriage to have letter-feed and return movement with the latter. The cross bar 41 carries a roller 45, which rides and supports the table on a rail 46 carried by a framework 47 secured to the main frame of the machine. As the web passes on to the table, the folds or plies thereof are separated and guided by fingers 48, securedto the machine at both sides thereof. The fingers 43 at one side of the machine are staggered with re- .spect to those at the other side, alternate fingers being secured to the same side of the machine, so that the fingers may project/into the oppositely directed fan-folds of the web.

A pair of lguides 49 for the edges of the web gage 54, carried by the bar 55 on the paper shelf, and may then be severed by drawing the web against the cutter 51,. The cutter is shown as a plate secured to a sleeve 56 on the shaft 12; to which sleeve is also secured a finger 57 for rocking the cutter into engagement with the web when the latter is to be cut. The printing on the web is eifected by types 58 which may be operated by the usual mechanism.

The carbon sheets, by means of the binding action thereon of the webs, due to the feed-rollers, are caused to advance with the webs at each line-space turn of the platen; and, when the platen is shifted upwardly, .as before noted, the carbon sheets are released and may be drawn ba ck along the webs from racemes edges to a traveling holder or carriage on the table 39. This carriage 59 may comprise a body portion or plate having a stepped block 60 at each side thereof. 61 to each of which one carbon sheet may be attached, are secured by screws 62 to the steps 63 of the blocks 60. The fingers 61, like the fingers 48, are staggered upwardly, alternate fingers being secured to the same side of the carriage 59, so that the oppositelyrdirected fan-folds of the web may each receive a finger.

Depending plates 64, secured to the ends of the carriage plate 59, each carry a pair of vertically disposed rollers 65, adapted to ride on horizontal flanges 66 on the side rails 40 of the table 39. Other horizontal flanges 67 on the table side rails overlie the rollers and hold the carriage to the table.

-lEor throwing back the carriage to move the carbon sheets backwardly along I the web, there is attached to the left-hand block 60, a handle 68.

The carbon-holding fingers 61 have heretofore terminated, at their free ends, inside of the margin or side edge of the web, so as not to catch upon the web. In the preferred form of the present invention, however, these fingers are convenientl used as means for cutting the Web at the olds thereof, so that the written length of the Web,'prior to its detachment from the rest of the web, may have certain, or all, of the plies thereof separated from one another. For this purpose, the fingers 61, or such of them as lie between plies which are to be cut apart, have their free ends in the form of cutters 69, which cross the line of the side edge of the web. As already stated, when a section of web has been written, the web is released from the feed-rollers and is drawn by hand to the gage 54; and, while the web is so released and held by hand, the carriage 59 is moved backwardly in order to position the carbon sheets in the length of web next to be'written. This backward movement of the carriage 59 causes the cutters 69 to sever the plies of the web for a distance therealong determined by the movement of the carriage in bringing t e carbon sheets to initial position. The cutting edges are preferably inclined inwardly and backwardly, as shown in the drawings, so as to split the web without tearing, crumpling or displacing it. When the web is fed into the machine with its edges already perforated, a relatively blunt cutting edge may be used. lln the form shown, the cutter consists of an inclined head 70 which is extended as a pin or lug on the end of the finger 61.

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