Definitions

  • the webs which may be parts of a fan-fold web, are carried around the'under side of a revoluble platen, and up in front thereof, the typwriting being done upon the front of the platen; and, in order to straighten out the webs to permit the carbons to be drawn back independently of the webs, a delivery guide or chute, extending upwardly and forwardly from the front of the platen, is swung forwardly, thus reducing the bend around the platen of the webs and carbons which are led into the machine horizontally at the rear of the platen.
  • the forward swinging of the delivery guide or chute also effects the actuation of a device for releasing the feedrolls which cooperate with the under side of the platen.
  • the guide or chute is provided with a knife to enable the tearing off of sections of the webs, and also with a gage for determining the length of the sections to be torn off.
  • A, releasable latch isprovided' formaintaining the guide or chute in its normal position.
  • An object ofthe present invention is to provide novel means to enable a. condensed record-sheet, in the nature of a carbon copy, to be kept.
  • a. condensed record-sheet in the nature of a carbon copy
  • there ma-yab employed a paper-shelf inclining forwardly and downwardly toward the bottom of the platen, to direct the record-sheet between the platen and superposed webs or plies; and. if desired, a roll may be provided upon the top of the platen for feeding this record-sheet and also for holding it during the manipulation of the carbon and web plies.
  • This roll or rolls may be carried upon an arm or arms, and may be released by means of a finger-piece; and an apron or guide may be provided at the rear of the platen to. guide the record-sheet back to the top of said rear paper-shelf.
  • Another object of my invention is to provide means whereby the platen and consequently-the record-sheet will be line-spaced when the upwardly-extending guide is swung forward to enable the webs other than the record-sheet tobe pulled forward.
  • provision may be made of a train of connections by which the usual linespacing slide of the Underwood typewriting machine will be operated up0nswinging the guide or chute forwardly. This provision relieves the operator of the necessity of effecting a separate actuation of the linespace mechanism in connection with the aduStment. of the webs and carbons and the subsequent severing of the webs; and guards against the superposition on the recordsheet of the first line of a new section on the last line of the previous section.
  • Figure 1 isa sectional side view of part of an Underwood typewriting' machine, modified to show one form of my invention as applied thereto.
  • Fig. 2 is a fragmentary perspective view of a carriage, showing the parts in writing position.
  • Fig. 3 is a fragmentary sectional side view of the carriage, showing the parts positioned for withdrawing the carbon sheets.
  • F 1g. 4 is a diagrammatic side view, showing the feed-rolls moved from the platen bv the usual feed-roll release handle. y
  • the carriage 5 is, supported upon a front rail, not shown, and a rear rail 8, which advantageously is located considerably lower than in the ordinary Underwood standard typewriting machine, so that webs 9, drawn over a rear paper table 10, will be guided carbon-paper carrier or carriage 14, which resembles in many of its details the usual Underwood fan-fold carbon-carriage.
  • the carriage 14 is shown as running upon rails 15, which form arearward extension of the typewriter carriage, said extension being supported at its rear end by a wheel 16 running upon a rail 17 forming part of a fixed extension 18 of the typewriter frame.
  • the webs 9 to the carboncarriage 14 may be drawn over a rear bar 19 of the carriage provided with any* usual or suitable form of edge gage, not shown. 'hen the webs are introduced into the machine, they pass over the aforesaid paper-table 10 to the rear feed-roll 11, and are then guided upwardly by an apron 20 supported on the platen frame in any desired manner, so that the webs pass between the front feed-rolls 21 and the platen 2, and then up in front of the platen to a swing I uide or chute comprising a paper-table 22.
  • lhe apron 20 may extend well up toward the printing line.
  • the swing paper-table 22 is herein shown as provided with brackets 23 at its ends, said brackets being journaled by hubs 24 upon the platen axle-3, to permit the swing, table to be swung forward from a stop 25 fast upon an end frame 26 of the platen frame, against which it normally rests, to the Fig. 3 position, at which it'is arrested by engagement of a. tail 27 thereon With said stop 25.
  • the angle through which the webs 9 and the carbons 12 between them are turned is only about 60, and it has been found that this arc of contact on the ordinary Underwood standard platen is sufficiently small to allow the carbons to slip over the webs sufficiently readily for the purpose in hand.
  • the operator draws the leading ends of the webs to be gaged against a suitable adjustable end gage 28 fast upon an upward extension 29 of the table 22, and then, while holding the webs in gaged position, pushes the carbon-paper carriage 14 rearward by means of its forwardly-extending handle 30.
  • the operator may swing the table 22 rearwardly to its Fig. 1 position, so that it will be caught in said position by means of a hook 33, which is adapted to catch over a pin 34 upon one of the swinging brackets 23, and hold the table 22 in its normal position.
  • the webs may then be severed by drawing them against the knife, the feed-rolls 11 and 21 being sufficient to hold the websfirmly during this operation.
  • ahandle 35 forming a bell-crank extension of the hook 33, and adapted to swing the same around shaft 36, against the action of a spring 37 which normally holds the hook in effective position.
  • a stop 38 holds the hook 33 in'position to be cammed upwardly by the pin 34, when the table 22 is swung backwardly.
  • the swinging bracket 23 may be connected by a link 39 to a rockarm 40,, fast upon the usual feed-roll-casting-off shaft 41 of the Underwood platenframe, the connections being such that when the hook 33 holds the table 22 rearwardly, the feed-rolls are effective, but, when the swing-table is in the Fig. 3 position, the feed rolls are automatically released.
  • pro vision may be made of a paper-guide or shield 42, which lies above the paper-table 10, and is supported at each end by a bracket 43, secured to the typewriter carriage 5.
  • the usual line-space-ratchet-wheel 44 is secured on the axle 3, and is actuated by means of the usual line-space-s'lide 45, operated, in turn, by a line-space-lever 46, the operative connection between the line-spaceslide and ratchet-wheel being effected by means of the usual pawl 47
  • the number of line-spaces through which the platen is moved at each actuation of the line-space-lever 46 may be varied, for one, two or three spaces by the usual line-spacecontrol handle 48.
  • the paper-table 10 is supported by means of abar 49, from whichextend posts 49, carrying bracket 50, which support the rails 15, said rails beingconnected by rods 51.
  • the mechanism so far escribed, is substantially the same as that disclosed in said prior application, Serial .No. 316,981.
  • the record-sheet when placed in the machine, passes from said paper-table 53 around the platen, and beneath the lower edge of the paper-table 22, being pressed against the upper part of the platen by means of an auxiliary feed-roller 54.
  • Said roller 54 is supported upon a shaft 55, carried by arms 56, securedto shaft 36, a handle 57 being- '58, connecting a lug 59 on said handle 57 with a pin fixed in'the platen-frame, the
  • a guide or shield 60 is secured to shaft 36, so that when the auxiliary. roller 54-is withdrawn from thc platen, shield60 will-be in proper position to receive and direct the forward end of. the record-sheet to the rear of the machine.
  • bracket 23 for engagement with the forwardend of the line-space slide 45. Forward, movement of bracket 23 will then effect, by means of the levers 63 and 67 and the line-space-slide 45, a line-space movement of the platen to advance the record-sheet.
  • the other steps of advancing the webs 9 to the end gage 28, retracting the carbons 12, and severing 'the typewritten sections of the webs, will then be effected in the usual order, and upon return of pa'per-table 22 to normal position the webs, the record-sheet and the inter pin 61 on bracket 23, engaging a slotivoted at 64 onleaved carbons will be in position to start work afresh, I

It is desirable to maintain the feed-rolls .in their released position when cast off by the finger-piece 74, so that both hands of the operative may be free to properly adjust a work-sheet around the platen.
  • the finger-piece 74 is effective to rock the shaft 41 through a greater angular distance, than when actuated by the swing-frame, so that the return springs have no effect to restore the feed-rolls.
