Definitions

  • the latter having provision for carrying carbons between the plies of the web, and for shi tin the carbons back, to face fresh portions or the web, as the typing proceeds;
  • the web usuall comprising a succession of printed forms, each of which is torn 05 as soon as typed.
  • An object or the invention is to provide improved means for adapting a machine of this type for use with, separate plies, of which one may difi'er from another in its
  • No. 266,133 is illustrated a device for pulling lengths of webs or plies olf from supply spools, preparatory to feeding the webs line by line around the platen, so that the linespacing mechanism of the typewriting ma chine will not he burdened with moving the heavy paper supply spools.
  • One of the objects of the present invention is to improve the device for culling the supply of webs off from the spec s for this purpose, and also to use the improved device for preventing or minimizing the relative creep of the separate. plies upon one another as they feed around the cylindrical platen.
  • a feature of the present invention resides in improved means for clamping the sheets to the carbon-carrier for the purpose aforesaid.
  • the sheetclamp or clip is in the form of a bar, which extends entirely across the webs, and possesses other features which will be hereinafter set forth.
  • the bar which clamps the sheets together, as already set forth, is caused to hold the sheets in register throughout the typing of each form, so that there is no relative creeping of the webs back of said clamp.
  • the webs are found to have their original or normal relationship; that is, their originalprinted forms register with one another upon. all the plies, since the latter are no longer in contact with or affected by the platen, but lie flat one upon another in the machine. In this condition the operator grasps the'typed were at leading edges, and holds them together while he proceeds to release the sheet-clamp, preparatory to pushing back the caruon-carrier.
  • his gripping device is illustrated in the form of a thin late, mounted upon a crossbar of the car on-paper carriage, against which the webs are clamped by a swinging bail, the latter in the form of a crossbar, so shaped as to be practically rigid, and pivoted toward the rear of the carbon-papercarriage.
  • This clamping bar may be normally held efiective (to prevent creepin light springsecurely gripping t e papers or webs by means of such cam.
  • the handle by which the carbon-papercarriage is menipulated may carry a light finger-piece by which the typist can overcomethe tension of the spring, and thus release the webs from the grip when shifting the carboncarrier back relatively to the webs.
  • the webs being properly alined at the beginning of writin the herein-disclosed clamp may be utilize to always hold them in alinement, so that forms originally printed thereupon will remain properly suplerposed.
  • the typist usually gives the webs t eir final advance after typing a form thereon, by seizing them with the fingers when the .platen is lifted from the feed-rolls, and then drawing on the webs while they are substantially straight. After thus being drawn forward, they may be held by the finger of the typist against the usual leading-edge gage while the clampis released and the carbon-carrier pushed rearwardly.
  • the webs are still held by the clamp, and their first gaged position relative to each other is restored when they are seized by the typists' fingers, and they may all be set to the leading-edge gage as soon as the clamp is released.
  • the clamp may again be permitted to seize the webs, after the carhons have been shifted back along the webs, with the result that the original alinement of the webs is preserved.
  • the platen is now thrown into writing position, and the typed sections of the web are detached, and the forms or sections next written upon will be found to have proper aiinement.
  • Figure 1 is a fragmentary perspective View of an Underwood fan-fold typewriter carriage, showing the present inventlon as applied thereto.
  • Fig. 2 is a perspectiveview, showing the relationship between the carbon-paper carriage handle and the fingerpiece.
  • Fig. 3 is a diagrammatic, sectional, side view, showing the platen "thrown up and the work-sheets gaged, and the carbonpaper carriage having released the webs to permit it to be pushed rearwardly.
  • Fig. 4 is a similar view, showing the carbon-paper carriage pushed rearwardly, and having again seized the webs.
  • Fig. 5 is a similar view, showing the carbon-paper carriage advanced to unwind additional web lengths from the rolls upon which the webs are wound.
  • Fi 6 is a view similar to Fig. 5, but showing the carbon-paper carriage pulled rearwardly by the weight of the sagging webs. by'a spring-actuated cam, a com arative y Fig. 7 is a sectional side view, taken from the side opposite to Fig. 1, but showing the spring, the cam and connections between them and the clamp when the clamp is effective.
  • Fig. 8 is a View similar to Fig. 7, but with the clamp shifted to ineffective position.
  • Fig. 9 1s a diagrammatic, plan view of the parts seen 'in Fi j 7 and 8.
  • Fig. 10 is a ragmentary, sectional, side view, showing the parts as seen from the side opposite to Fig. 7
  • Fig. 11 is a perspective view of the detached upper portion of a carbon-paper carriage, showing a modification i which the clanp is adapted to be held effective at both on s.
  • Fig. 12 is a view similar to Fig. 7 but showing the additional connect1ons of Fig. 11.
  • the platen 20 is revolubly mounted by stub shafts, not shown, in a swing frame which includes-a front paper-table 21, journaled on a shaft 22, said shaft extending between the ends 23 and 24 of the carriage, which latter travels upon a rail 25.
  • the types 26 on type-bars 27 strike against a work-sheet 28 upon the platen and passed from behind over a paper-table 29, at the rear of the platen, said table forming part of the carriage.
  • the usual side gages 44 adjustably mounted upon the rear bar 35, and the carbon-paper carriage is likewise provided with the usual adjustable side gages 45, which can be made fast to the side bars 46 of the top frame of the carbon-paper carriage. Since there are only illustrated three webs 28, 30 and 31, there are shown only two carbon sheets 47 and 48, which are attached to the carbon-paper carria e crossbars 38 and 39, and lie between t e outer webs and the central webs and extend forward around under the platen 20.
  • the paper-table v21 is provided with the usual ad ustable side gages 49, with the result that when a form printed upon the web 28 has been fully typed, the typist may swing the swing frame around the shaft 22 and draw the webs to the Fig. 3 position against the usual adjustable end gage 50, paying no attention to the edge alinemcnt of the webs, since that is automatically cared for by the side gages 44, 45 and 49.
  • a handle 51 by which it is normally held down to hold the platen 20 against the feed-rolls 42 and 43.
  • the typist pushes rearwardly the usual hook 52, which engages a pin 53 upon the handle 51, and then draws upon the handle, with the result that the platen swings to the Fig.
  • a second bail arm 72 at the other side of the machine, which is drawn upon by a similar spring 73, and the bail arms 70 and 72 are connected by a rock-shaft 74, pivoted or journaled in the side bars 46, and bent downwardly at 75 near each end, so that its middle portion 76 will be completely clear of the path of the webs 28, 30 and 31.
  • the finger-piece may be released, thus permitting the swinging .jaw 61 to clamp the webs against the fixed jaw 62.
  • the jaw 61 is drawn down to clamping position by the springs 71 and 73, and is also clamped down because the follower 68 is thrown forward by the tension of the spring 78, which draws the extension 66 rearwardly, with the result that the follower rides up upon a cam 79 formed on the bail arm 70, with the result that the jaw 61 is cammed firmly down against the webs, the cam 79, for this purpose, being rather flat.
  • the typist swings the platen to the Fig. 5 position. bringing the webs 28, 30 and 31 against the feed-rolls, and then draws forward the carbon-paper carriage while drawing upon the handle 65, thus making a loop at 80 and unwinding the webs.
  • the weight of the webs behind the rear bar 35 will usually draw the carbon-paper carriage rearits bail arms 70 and 72, and its rock-shaft,
  • a hook 84 adapted to engage a pin 85 upon each jaw, said hooks forming rock arms fast upon a rock-shaft 86 lying below the jaw 62.
  • the hooks 84 may be actuated from the extension 66, and, for this pur pose, the left-hand hook or farther one, as.
  • the shaft 86 is journaled in ears 89 fast on the'bottom of the usual plate 90, which .is detachably held on the body of the carhon-paper carriage by the usual lugs 91. It will be observed that the shafts 74 and 86 not only stand completely clear of the webs, but also stand clear of the plate 92 forming the body of the carbon-paper carriage.
  • the flexible plate which forms the jaw 62, is advantageously held in position by lying upon the plate 90 and passing under the side pieces 46, so that the usual screws, not shown, which hold said side pieces in place, also hold the flexible plate jaw 62 in position.
  • the extension 66 may have a U-shaped portion 93 embracing the front end of the handle arm ,94, so as to bring the fingeriece 64 and the handle 65 in line with eac .other,
  • the handle may be provided with a pin 95 lying within a slot 96 in the extension 66.
  • a flexible jaw adapted to underlie webs extending across the carbon-papercarriage, a rigid jaw adapted to be swung against the flexible jaw to grip the webs therebet'ween, a spring normally drawing said jaws together, a rock frame including said rigid jaw, a cam on said rock frame, a handle for the carbon-paper-carriage, a finger-piece adjacent said handle, and a follower operated by said finger-piece adapted, when moved in one direction, to engage said rock frame to swing said rigid jaw away from the flexible jaw, and, when moved in the other direction, to engage said cam to force said rigid jaw against said flexible aw.
  • said cam to make the jaw effective and tobe swung in the other direction to lift the jaw to ineffective position, a hook for bold ing each end of the jaw, a rock shaft carry- ,ing said hooks, and means for rocking the last-named shaft at the operation of the follower.
  • swinging jaw extending across the carbonpaper carriage, a rock shaft journaled in said side pieces and forming the support for said swinging jaw, springs normally drawing on the swinging jaw to hold it efiective at each end, a finger-piece adapted to be swung to make the jaw ineffective, a hook for each end of the swinging jaw, a rock shaft carryin said hooks, and a link connected to the gnger-piece for operating said last-named rock shaft.
  • 'aw adaptedto be e :the carbon-pa of a carbon-paper carriage upon said traveling carriage, a flexible aw adapted to underlie webs extendin across the carbonpaper carriage, a rigid jaw adapted to be swung against the flexible jaw to grip the webs therebetween, a spring normally tending to swing the rigid jaw against the flexible jaw, a cam operated independently of said spring for gripping the jaws together, and a hook for each end of the rigid jaw connected to be operated by the cam.
