T YPEWRITING-MACHINE.

npplication filed Noirember To all whom it may concern:

Be it known that I, JEssE 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 aspecification.

This invention relates to typewriting machines in which plies of web are led into the machine for typing several copies simultaneously and tearing ofli sections when. typed. It is found in practice that the drag of the webs upon the line-spacing mechanism of the typewriting machine may sometimes lead to faulty results, especially if the line-spacing handleis operated sud denly. The feed rolls provided upon the typewriter are properly effective for use with sheets of paper of ordinary length; but in some cases they may proveinefiioient for unwinding the webs from the rolls or spools,

especially where several very large rolls of paper are employed. These rolls have great weight, and are not readiily started into rapid rotation by the pull thereon of the webs as they are drawn forward by the platen and its feed rolls. a

In my application No. 242,734, filed July 1, 1918, no w Patent No. 1,288,720, granted Dec; 24:, 1918, there is provided means" for automatically unwinding webs from the rolls, so that no extra burden will be placed at any time upon the line-feeding rolls of the typewriter. The object of the present invention is to provide a .simple device for thispurpose, and the invention is shown as applied to a typewriting machine of the class disclosed in the patent to Wernery & Smith, No. 1,132,055.

' 'In practising the present invention, the operator pulls the webs off from the rolls manually,preparatory to 'typing the page attention from theoperator, and the device is simple and readily applicable to existing machines. When theplaten is thrown up to I 'straighten out the webs, as in said Werne & Smith patent, the operator pulls the sheets forwardly and impales them upon one or,

' morere-registering pins. While the sheets I are held upon these pins,

the sheets, pins and all forwardly to a certhe operator pulls tain point, which may be predetermined by means of an adjustable gage. The operator Specification of Letters Patent.

then shifts back the carbons independently of the web, to positions to cooperate with fresh portions of the webs, as set forth in said WVernery & Smith patent. During this carbon shifting, the work sheets or webs are-retained upon the re-registering pins at 3 "the position determined by said adjustable gage, as just explained. Thereupon the operator, by an'additional manipulation, unwinds-all the webs from the rolls. This is done by pulling forward the webs together with the re-registering pins, as well as the carbons". This movement continues to an extent determined, by a second adjustable gage. By this time enough of the webs is paid off from the spools to furnish a supply for the next form, so that during the typing of said next form, the spools may remain stationary, and therefore have tobe stirred by the line-spacing operation of the typewriter. It will be under: stood that the carbons have been brought forward together with the webs during the unwinding operation; but this movement of the carbonsis an idle one. The operator now proceeds to carry back all-of the sheets, including 'the webs and carbons, to position them preparatory'to beginning the typing of the next form.. The length of this return stroke is determined by a rear stop,

which the carbon-carriage strikes. Further advantage is gained by clamping webs together during this return stroke, and the operator at this time needs to pay no further attention to holdin'g the sheet upon the 're-registering pins. After the carboncarriage is thus returned for the second time,

the webs will hang in loops from the spools,.

Fig. 6 is a similarview showing the, webs as finally retracted by the carbon-sheet carriage just before swinging the platen to writing position.

if then the desired entries are made.

In the usual nderwood fan-fold typewriting machine of the type shown in the patent to \lVernery & Smith, No. 1,132,055, the typewriter carriage 1O slides along a rear rail 11 and a front rail, not shown,

and has journaled therein a swing frame 12, in which is journaled a platen 13 adapted to-form a writing support for the outer web '14 and the inner webs 15. To enable the usual line-space handle 16 to advance the platen by the usual ratchet wheel 17,

is drawn along by the usual spring barrel,

not shown, under the control of an escapement mechanism, not shown, so that types 23 may print upon the outer web or worksheet 14. Between the outer web 14 and each of the webs 15, there is a carbon sheet 24. Said sheets 24 are supported usually upon the cross-bars 25 of a supplementary carriage 26, which is adapted to travel frontwardly and rearwardly along the rails 27 of the rearward extension 28 of the typewriter carriage 10.; -The webs 14 and 15 are adapted to be drawn over the rear bar 29 of the extension 28 between side gages 30 and 31,

and threaded between the cross-bars 25 which mayextendalternately as usual from opposite sides beyond the centerof the supplementary carriage 2.6. From here the webs are carried forwardly and downwardly over the paper table 33, and then under and upwardly in front of the platen 13, where they pass up over-a front paper table 34 provided with adjustable edge gages 35.

To write a form at the beginning of a days work, the carbon sheets are properly adjusted relatively to the form already printed on the web or webs 14 and 15, and After finishing the typewriting of the entries, the typist swings the t pewriter platen 13 to the position seen in ig. 3 by pressing rear- .wardly the hook 36 which normally holds the swing frame 12 against the feed rolls, not shown, and then drawing the handle 37 forwardly, with the result that the swing frame 12 rotates around the shaft 21 to the Fig. 3 position. Before doing this, or else immediately after swinging the swing frame,,the typist impales the openings 38' on the webs 14 and 15 upon pins 39 fast on a slide 40, so that when the platen 13 is in the Fig. .3 position, the webs and the carbon sheets 24 will be positioned as shown in Fig. 3.

The typist then pushes the carbon-sheet carriagerearwardly to the Fig. 4 position by means of the handle 43. The handle supports a finger-piece 41 which is adapted to operate a clamp 42, whose utility will appear later. The connections between the finger-piece 41 and the clamp 42 include a link 44 pivoted to the finger-piece 41, so that, as the finger-piece swings rearwardly around its pivot 45 against the pressure of its spring 45, it will swing rearwardly a rock-arm 46 to which the rear end of the link 44 is pivoted, thereby rocking the shaft 47 to which the rock-arm 46 is fast, so that the clamping member 48, forming a second arm on the shaft 47, may clamp the web against the cross-bar 49.

When the carbon sheets have been pushed rearwardly, as just described, the parts occupy the Fig. 4 position. The typist now grasps a handle 50, upstanding from the slide 40, and depresses a finger-piece 51 against the tension of a spring 52, so as to swing an L extension 53 of the finger-piece clear of the stop 54, thus enabling the typist to push the handle 50 along the support 55 carrying-with it the pins 39 and the webs impaled thereon. The typist pulls the handle 50 along until it reaches the Fig. 5 position, in which the slide 40 is arrested by a stop 55, said stop being so placed that,

in moving from the Fig. 4 position' to the Fig.5 position, the web measures by its advance the length of a single form printed thereon.

It will be observed that at the time of drawing the webs to the Fig. 5 position, the

webs are. advanced the length of a single form printed thereon. It will be also observed that at the time of drawing the webs to the Fig. 5 position, the webs are unrolled from the rolls 57, 58 and 59, on which they are wound. The typist then grasps the finger-piece 41 and clamps the webs against the cross-bar 49, and pushes rearwardly on the handle 43, thus carrying rearwardly the carbon sheets and the webs bodily to such a position that, when the swing frame 12 is swung back into place, the knife 56 will stand exactly at the point at which it is desired to sever the webs. This produces the slack portions 60 shown .severing the webs in Fig. 6, from which the webs may be drawn during the next operation of line spacing, while writing, without the strain of unwinding them from the rolls 57, 58 and 59. j Y

When the webs and carbon sheets are in the Fig. 6 position, the typist swings back the swing frame 12 into the typewriter carates the usual handle 61 to operate the knife 56 to sever the webs, thus, as pointed out, at exactly the proper point and clear of the carbon sheets. The stops 54 and 55, referred to above, are adju'stable along the extension 55*, being for this purpose provided with-thumb screws 62 adapted to be screwed'onto threaded extensions 63 which pass through an open slot 64 in said extension, and are provided with heads 65 to engage the back of the extension.

In order to limit the backward movement- .carriage 26 in moving- .of the carbon-paper from the Fig. 5 position to the Fig. 6 position, so that the webs may be moved precisely the length of a form'onthe web, thereis provided an adjustable stop 66 adapted to be set in any one of a plurality of openings 67, and against this the rear portion of the carbon-paper carriage 26 is adapted to strike. The slide 40, on which the pins 39 are carried, it will be noted, usually travels be may jump rearwardly atthe moment tween the stops 54 and 55 only, and, if, a whole form has been used, is usually at the Fig. 6 position when the platen is thrown back to the Fig. 1 position. Since the Webs they are. seized between the platen and the rolls 68 in settling down to the Fig. 1 posi stead. of

tion, the slot 64 extends down toward the platen beyond the stop 54, and .the stop 54 may normally/lie in the path of mpvement of the slide 40 when advancing the webs, in-

blocking the slide against being drawn toward the platen. In order to prevent the stop-1541 from turning in the slot, its-shank may be flattened as at 69 to fit the slot The slide 40 may be held true to the guide or support byslots 70 in U-shaped supports:71 embracing the guide. j
