BUBNHAM C. STICKNEY, OI RUTHERFORD, JEBSEY, .ASSIGNOB TO UNDEBWOOD TYPEWRITEB COMPANY, OF NEW YORK, N. Y., COBPORATIONDI I rrrnwnrrme momma Application filed June 6,-

To all whom it may concern:

Be it known that-I, BURNHAM C. STICK TNEY, a citizen of'the United States, residing indefinite length, according to the number of forms which compose the same. Ordinarily, however, or at least until so worn as to call for replacement, a fixed length of carbon-sheet is employed; the'carbons being shifted, relatively to the work-webs from one form-length to the next succeeding form-length of work-webs when the typing of -a form is completed. The usual practice has been; after typing of a form, first, to lift the platen bodily to release the web therefrom and to release the carbons for their shift; then to shift, one form-length rearward, a carbon-carrier with the-carbons attached thereto, while holding the workwebs; and thento reset the compositeweb for commencement of typing on the next form and to replace the platen.

In the co-pending application of Jesse A. B. Smith, Serial No. 640,315, filed May 21, 1923, there is described a machine, operating according to a somewhat different method. for obtaining the same results, and

whichhas certain advantagesas to lightness, simplicity and expeditiousness in its manipulation. In this Smith machine. neither the platen nor-a carbon-carrier need be shifted in the carbon-shifting operation. The carbons are anchored at their rear, and

sufiicient slack is, provided the composite web between the platen and the anchorage of the carbons to permit writing of a form before such slack is entirely taken up by the line-spacing movements of the platen. After completion of a form, the procedure is: first,'to'-reverse the platen until the car- 'bons are clear thereof and are loose in the provided.

1923. scmi'no. 843,667.

- work-webs; aslack iii the carbons and workwebs being thus re-established between the platen and the carbon anchorage; then, rock against the composite web an arcuate table to bend the web until the slack is removed; then, to rotateithe platen to shift the work-web a form-len h forward-while the carbons are held stationary; and then,'-

to return the rocking table to normal pos1- tion, re-establishmg the slack; after which further forward rotary movement of the platen will serve to bring the composite web on the fresh form-- therein, originally to position for typin length, with the slac The present invention relates morexparticularly to a machine of the general class of the aforesaid Smith machine; and has for its object the provision of means where by a device, such for instance as the era cuate rocking table of Smith may be utilized not only to take up the slack in the carbons, preliminary to the shift of the web relatively thereto but which may also be.

utilized itself to effect the relative shift of the work-webs and carbons; and whichmay perform first the one, and then the other,

operation in a single continuous movement.

In the embodiment of the invention, here? inafter shown, the same comprises means for clamping or holding the work-webs for ward thereof after reverse movement of the platen has released .the carbons, with the; rear ends of the work-webs. free. (the carbons being then held at their rear ends,.andf* free at their forwardends); and provides for a movement of the-rocking table not merely sufficient to take up the slack thenin- 7 the carbons, but sufficient alsoto draw'the work-web's forward a form-length over the .carbons and provide sufiicient loose work web to re-establish the slack or loop.

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

In the accompanying drawings,

Figure 1 IS a sectional elevation, showing ioo a fragment of the machine seen at Figure 2, the compositev web being in position prepar'atory to typing a fresh form on the web.

Figure 2 is a section, taken longitudinally through the typewriting machine, and showing the position of the parts after the platen has been turned backward to clear-the carbons therefrom, preparatory to effecting a.

slack in the Work-webs and carbons.

Figure 4 is a view similar to Figure 3, ex-

cept that the rocking table has completed its movement, and thereby effected the shift of the carbons.

Figure 5 is a top plan view of the machine, and shows the parts in the position indicated in Figure 2..

Type-bars l0 strike against the front of a'revoluble platen 11, which is journaled as usual in a platen-frame comprising ends 12 and arear aper-shelf 13. The usual releasable fee -rolls 14 run uponthe under side of the platen. The platen-frame 1s mounted upon a carriage 15, which slides along a rail 16 for letter-feeding movements. The platen is rotated line by line by means of the ordinary line-spacing mechanism, comprising a line-space wheel-17.

The work-web, usually com rsing superposed plies 18 (which may be oose plies or else may consist of a fan-folded web), may

be drawn up from a supply-spool or from a zigzag folded pile, which may be contained .in'a receptacle arranged in rear of the typewriting machine and its stand 21. As the plies of work-web rise from the supply at 19, they pass up through a support or guide,

point in op under the rail to which may comprise a" front guide-bar 22 and a rear guide-bar 23; these bars spaced sufiiciently to accommodate the plies of web confined therebetween, and also sufficiently to accommodate a number of blades 24, 25,

whichare inserted between the plies of work-web, and upon which are'caught sheets of carbon 26- which extend upwardly between 1 the plies of work-web. These blades may osite directions between the plies, especia ly when the web is fan-folded; and each blade may be su ported at its hilt upon one of the web-'gui ing end-pieces 27 by which the front and rear guide-bars 22 and 23 are connected. The parts 22, 23, 27 taken together may-form an eye or guidebracket which is fixed upon the front of a traveling bar 28, the latter forming a portion of a framework-that is secured to the typewriter-carriage 15 to travel therewith; said bar 28 having a roll 29 to .run upon a rail 30, and also having a. finger 31 to catch prevent lifting of the frame. Said frame also comprises upward ly and forwardly extending opposite arms 32, attached by screws 33 to the ends of the bar 28, and connected at their front ends to the ends of the typewriter-carriage 15. The web guiding and holding device therefore travels with the typewriter-carriage.

At Figure 2 is-sho'wn the composite web, comprising work-webs 18 and interleaved the typing of the form shift bons, which is to be effected while the car-.

carbons 26, all in slack condition, preparatory to the typing of a form upon the web; the slack being preferably in the form ofa loop 34 hanging down in front of the guiding and supporting means 22 and behind the platen 11 the slack being suflicient to permit the completion of the line-by-line typmg of a form printed on the taken up.

The rail 30' is supported on the rear ends of fixed arms 35, rated sufliciently edggewise travel ofthe loop of composite we as it conforms with the movements of the aper-carriage 15; said arms 35 being fixe by screws 37 or otherwise tothe rear end .of the base 38 of the typewriting machine.

At Figure 1 is shown diagrammatically web as the slack is 'the composite web drawn forwardly far enough to permit the carbons 26 toextend adjusted or determined by means of a leading-edge gage 40, which is mounted upon a:

staff 41, which extends upwardly under and beyond a front paper-table 42, the latter extending upwardly and rearwardly from the top front portion its delivery side. From the Figure 1 position the first typing of a form proceeds line by line, the slack 34 in the'composite web being gradually taken up as the typing proceeds; and isfinished as soon as or before the slack at 34 is, all taken up. At this time the leading edge of the web extends up beyond the gage 40, and theinterleaved carbons 26 extend up along the front paper-table 42.

Upon the completion of the first typing of a form (i. e., the second printed formon the web), the platen is rotated backwardly by means of the usual end knob or fingerpiece 43, until the requisite slack in the composite web is produced again at 34, or until the interleaved carbons 26 have been retired to a point in rear of the platen or its feed-rolls 14, as at Figure2. For this purpose, the retraction of the composite web proceeds until the'leading edgeof. the web uncovers agage orindicator 43, atwhich point the retraction of the web ceases.

This retirement of the plies of work-web and carbons tothe Figure 2 position is "preparatory to effecting a relative longitudinal between said work-plies and the carbons remain stationary. It will be borne in mind thatthe carbon-sheets are fixed to the blades 24, 25, and that the latter are fixed to the guide-bracket or frame 22 and carriagebar 28. It is desired to pull the workof the platen, that is, from which are spread or sepa to permit the requisite webs or plies 18 forwardly while the carbons arestationary until the form on the -web,

which succeeds the form just typed, is advanced far enough to co-operate with said carbonsfor typing thereon. In other words, the extent of the relative shifting between carbons and work-webs should equal the depth of a printed form.

Preparatory to effecting this relative longitudinal shift, it is desired to take up the slack in the carbons (which is understood at Figure 2), or tauten them more or less, so that they will not themselves be dragged along or caused to advance when the plies of work-web are pulled forward. To take up the slack of the carbons, there may be used a suitable device, as, for example, a table 44, broadly curved from front to rear, which may be made of sheet-metal, and may be mounted upon a pair of end frames 45, which, by means of a rod 46, are hinged to upstanding arms 47, the latter secured at their lower ends at 48 to the typewritercarriage 15. The swinging frame may-thus comprise the end frames 45, the curved table 44, and the hinge rod .46, and may normally hang (Figures 1 and 2) between the side arms 32 of the rearward carriage-extension, and extend down behind the typewriting machine and the desk; the side arms 32 being connected by a rod or bar 49 at th ir forward ends, and affording a support against which said curved table-frame may hang.

From the idle position at Figure 2 the table-frame may 'be swung up by means of a handle 50, connected to one of the side frames thereof, to the position shown at Figure 3', to take up the slack in the composite web.

Prior, however, to movement of this tableframe from Figure 2 to Figure 3 position, the work-webs 18 are clamped to the front paper-table 42, to, prevent rearward displacement of the work-webs from their position with their leading ends at the gage 43 The clamp employed for this purpose com prises a bar forming part of a bail; this bar being affixed to arms 66 fast on a rockshaft 67. The shaft 67 is journaled in brackets 68 secured to standards or brackets 69 which are unitary with the front papertable 42. The standards 69 have laterallyoffset flanges 70 which rest upon flanges 71 on the side pieces 12 of the carriage, and which are secured to the latter by screws 72. By means of a finger-piece 73 on. an arm 74, also fast to the shaft 67, the bar 65 may be swung against the lower front part of the aper-table 42 to clamp the workwebs. X spring 75, connected to the arm 74, and to one of the standards 69, serves to release the work-webs when the finger-piece 73 is released. 5

At the time, therefore, that the table 44 is swung from Figure"2 to Figure 3 position, the work-webs are anchored forward of the table 44, but are free to the rear ofv that table. Further movement of the table 44, from Figure 3 to Figure 4 position, consequently results in the introduction into the machine of' a fresh length of work-wens from the container below the 'bar'23. The

table 44, and the movement thereof, are so proportioned that the table in moving from Figure 3 to Figure 4 position advances into the machine one form-length of work-web; and, since at this time the carbons 26remain stationary or unadvanced, there is effected a shift of the work-webs relatively to the carbons, to cause the carbons to leave the last ift- I on an arm 53 rising from one of the framearms 32, to limit the upward stroke of the curved table-frame.

Having so shifted forward the plies of I work-web, the operator releases the handle 50, and permits the table 44 to drop to the idle position (Figure 2), thus permitting slack to form again at 34. The operator then revolves the platen forwardly, thereby advancing the composite web until it strikes gage 40, Figure 1, thus bringing the carbons to position to co-operate witlnthe types 10, and positioning the new form properly for the reception of the first line of typing; and the typing of the new form then proceeds line by line as before.

Preferably before the typing of a new form begins, the first form may be torn off from the web by means of a knife-edge 58', as indicated at Figure 1, said knife being secured above the front paper-table 42. The latter may have an opening 60 midway of its ends, through which may be seen the staff 41-and the gage 43 thereon. The leading edge of the web passes up beneath the knife 58, or between the same and the front table 42. The firstform at the top of the web is wasted, not having been typed. The second form, which is typed, and which now be comes thenew top form, remains in the machine until the typing of the second following form is about to begin, whereupon such new top form is torn off by the knife-edge 58. Thus itresults that one typed form always remains in the machine, for convenience in manipulating and gaging the workwebs and carbons. The gages may be independ'ently adjustable along the staff. It will be seen at Figures 3 and 4 that the rear paper-table 13 may be about tangential to the curve or arch of the elevated curved paper-table 414, of at least that the reach of composite web at 56 may be tangential to both the curved table and the platen, thus avoiding at this place the carrying of the composite web over sharp bends or corners, which would tend to cause the carbons to bind between the plies of work-web, and would therefore hinder or prevent the desired relative slipping of the carbons and work-web pliesat the described shifting or readjust-mg operation. The curvature of the table 44 may be very slight, so as to conduce to free slipping between the work-web plies and the carbon-sheets during such shifting operation. It will be seen that at its front end the curved table is preferably in rear of the platen, and preferably above the same, so that the reach 56 of the web need not turn over any sharp corners; the table curving up from its front end, and gradually changing the path of the web by curving back wardly' and then downwardly to a point above the stationary guide 22, 23, and being in such relation thereto that the reach of composite web 57 may extend-downwardly tangentially from the paper-table and vertically through the guides, so as to avoid turning this portion also of the composite web over any corners. Thus the web may'rise from the supply spool or pack, into the typewriting machine at 22 and change its direction of travel gradually upwardly, forwardly and downwardly to the platen, in such a manner that undue friction or binding between the plies of the web may be avoided. during the pulling forward of the web for the relative shifting operation.

Only the forward portions of the sheets 96 need to be carbonized. The rear portions, npon'which no typeeimpressions ever ble material.

The severing knife 58 may be made adjustable to accommodate different lengths of fall, may be mere blank paper'or other fiexi- Z 1 forms, being, for this purpose, connected by screws or fastening devices 62 to arms or brackets 63 extending upwardly from the ends of the front paper-shelf 42, and having slots 64 to accommodate the adjustment of the attaching screws 62, the latter passing through the slots.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used withoutothers.
