TYPEWRITING MACHINE.

Application led May 11,

To aZZ whom t 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 5 State of Connecticut, have invented, certain new and useful Improvements in Typewriting Machines, of which the following is a specification. v

The present invention relatesto continuous billing'typewriting machines, one form of which machine is showng in the patent to IVernery vand Smith, No. 1,132,055, granted March 16, 1915.

In a machine of this type, work-sheets or webs are used in several layers or plies, each provided with printed forms constituting one piece of work, which, when completed, may be torn from the continuous web. Carbon-sheets interleaved -between the webs or plies are mounted on acarboncarriage, so as to advance with the web toward the platen while, typewriting, and so as to be drawn back by the carbon-carriage into the succeeding form-section of 7 the web, after the leading form-section has been typed, and prior to detachment from the web of such leading form-section. In

conjunction with such individual-formwebs, record-sheets are often employed, upon which record-sheets the writings on the individual forms are accumulated and condensed as they filling in of the forms progresses; and, to provide for this condensation, the record-sheetsare ordinarily held against movement while the form-webs are advanced for the detachment of a form which has been filled invand for the positioning of the succeedingvform. These record-sheets have heretofore been individual sheets, replaceable wheniilled. Y For convenience, the Vform-webs are preferably led from web-holders on Va cabinet at the rear of the typewriter -stand; over the rear of the stand; to a carbon-holder on a table connected to the rear of the typewriting machine, and thence down and'around theplaten in the usual manner. Y I

A feature of the invention is the provision of a take-up device for the written portion of a record-sheet, fed to and from y the platen in the form of a continuous web so as to be of a length such that the abovereferred to, comparatively frequent, replacements are unnecessary. A feature of the invention is the adaptability of the take-up 1922. Serial No. 560,031.

device to use in conjunction with webs other than a record-web. For instance, instead of detaching sections from the form-webs as the same are written, the present takeup device may be used to gather up and hold the form-webs until such time as may be desired to separate and use the individual forms.

A further feature of vthe invention is the provision of means whereby the web-take-u'p device,`preferably located out of the way of the operator, at the rear of the typewriter-stand, may be actuated by the operator from the latters position at the front of the stand; and, in this connection,a feature of the invention is a take-up device and means for feeding the written portion of` the webthereto such that constant attention thereto by the operator is unnecessary,

the take-up device being operable at will; and at convenient intervals only, and the web feeding and guiding apparatus being such that the written part of the web may be allowed to accumulate as a slack on the fioor or elsewhere until such time as it may be convenient forthe operator to gather the same into the v,take-up device.

A feature of the'invention is the provision of means whereby a record-sheet in the form of a web may be fed, in superposed relation to individual-form-webs, to the platen by the usual line-space movement of the platen, but which may be held against movement while the other webs are moved for the detachment andv placement of the successive sections thereof; and the provi-V sion of means whereby the written portion of the record-web may be diverted from the otherv webs, thence to be led tothe take-up device. a l j l In the preferred "form of the invention, a cabinet such as ordinarily contains Vindividual-form vweb-holders at the rear ofr the typewriter-stand also contains a supply roll or holder for the record-web and the take-upA device or roll for the latter, and there is provided an actuating connection extending under the typewriter-stand from the take-up device, carrying a pedal, by means of which the take-up device may be actuated by the operators foot.

Other features and advantages will hereinafter appear. v

Inthe accompanying drawings,

Figure 1 is a View in side elevation'of the web-cabinet, typewriter-stand and recordsheet pick-up device; the typewriter being indicated on top of the stand with the webs connected thereto.

Figure 2 is a view in side elevation, partly cross-sectional, of the platen-frame, platen and certain associated devices shown in their normal or printing positions thereon.

Figure 3 is a detail view showing the record-sheet pick-up device and connections thereto andthe actuating device therefor.

Referring to thev drawings, the typewriterstand is indicated by atop or table piece 1, uprights 2 and suitable braces 3. It will be understood that the stand or desk` may be of any style which permits feed of the webs from the rear thereof to the typewriter.

The typewriter l is indicated in dotted lines on the stand. The particular style of typewriter, here intended to be shown in illustration of the invention, is that disclosed inA United States Letters Patent to Fortin, No. 1,237,319, of August 21, 1917, of which the carriage of the typewriting machine has attached thereto a rearward eX- tending table 5, on which acarbon-holder 6 is adapted to move with the carbons and webs toward the platen 8 as the carbons and webs have their line-feed movements around the platen, and which is adapted tobe moved backward with the carbons to draw the carbons into successive web-sections after the leading` web-section has passed around the platen. It is unnecessary here to describe in detail the structure of the table on which the carbon-holder operates, reference being made to the aforesaid Fortin patent for such description thereof as may be desired. Suffice here to say that the carbon-holder of the Fortin patent comprises a plate 7, having ,secured thereto a number of clips (not shown), each of which clips engages and holds the rear end of a carbon-sheet, the several clips being steppedup one from another more conveniently to enter and slide between the superposed web-pieces.

In the Fortin patent, a single fan-fold web is shown; the superposed fan-folded sheets or st 1ips forming the web each being composed of detachable units bearing the same individual form or blank. Instead of a single web comprised of fan-folded superposed strips or sheets, several single strips or webs, as illustrated in Figure 1 of the present application, may be employed; each of the superposed webs being composed of detachable units bearing the same form or blank.

As shown in the aforesaid Fortin patent, the carbon-holding plate 7, with the carbons attached thereto, interleaved with the webs, is detachably secured to a carriage 9, which moves therewith on the table 5 to and from the platen, as above described. r1`his detachability of the carbon-holders permits the same to be interohanged.; that is to say, permits a carbon-holder, with carbons interleaved with webs comprising forms of one character, to be substituted for another carbon-holder, with attached carbons and webs comprising forms of another character; thus avoiding the necessity, at the time of substituting webs of one form for webs of another form in the machine, of interleaving` the webs bearing the desired forms with a set of carbons and attaching the latter to the carbon-holder. ln other words, the webs of each set or style of individual form, which the operator may be called upon to use, have their carbons interleaved therewith and attached to one of the several carbon-holders. The carbon-holder of the selected web-form is then substituted for the carbon-holder for the web-form which may be in the machine.

ln a fan-fold machine such as described, the platen is lifted after the printing of each individual form` or length of the webs, so that the webs may be freely and horizontally drawn forward to position another section thereof with respect to the platen. At this time the record-sheetI is clamped against movement so thaty the writings which appear perhaps at a small part only of the individual forms may follow each other on therecord-sheet without the intervening spaces, which, on the webs, are occupied by printed headings and other matter not wantedI on the record-sheet. ln other words, the writings on the recordsheet are condensed, and the clamping of the record-sheet, when the individual form webs are drawn forward, is to eliminate the unnecessary spacings on the record-sheet referred to. Normally the platen is locked in printing position and the record-sheet clamp is held clear of the record-sheet. rlhese features, which are well-known in the art, will now bedescribed only in so far as may be desirable forr a clear understandingV ofthe present invention.

Referring to Figure 2, the platen 8 is shown as revolubly mounted on an axle 10 carried at each end in an arm 11 pivoted at 12 to the platen-frame 13. On the frame 13 is the usual paper-guide and apron 1st;r and on the frame 18 at the rear of the same are brackets 5a, which support the forward cross-piece 5b of the table 5, hereinbefore referred to. When the platen is in printing position, as shown in Figure 2, the usual front and rear pressure feedrolls 15 and 16 engage the same through openings in the apron 14. The arms 11, by means of which the platen is swung up and down between its printing station and its web-positioning station, form part of a frame which is extended, as indicated at 17, to the rear of the platen. To this swinging frame 17 is attached a paper-table 1S lli) " therewith.

and a gage-piece 19 having a slidably-adjustable gage 20 thereon, to which slidable gage the leading ends of the webs may be drawn preliminary to detachment' o-f 'the leading web-section. The swinging frame also carries a knifev21 against which the typewritten web-sections may be drawn to sever the same from the webs. The swinging frame 17, when the same is in printing position, rests at its rear upon a shaft 22, which has its bearings in the frame 13.

The swinging platen frame is locked down in printing position by means ofhooks 23 on arms 24, which arms are fast to the shaft 22; the shaft 22 being a rock-shaft. For engagement by the hooks 23, the side pieces of the swinging frame 17 each havea pin 25 over which the hooks 23 snap when the swinging frame has been dropped by gravity to its position of rest cn the shaft- 22. The hooks 23 are snapped into locking position by means of a spring, not shown, but which is preferably coiled on the shaft 22. One of the arms 24 is extended, as indicated at 26, `to carry a finger-piece 27 by means of which the hooks may be swung rearward out of engagement with the pins V to permit the swinging platen-frame to be lifted when a new section of web is to be positioned. The swinging' frame 17 may be lifted by drawing on the upper edge 28 of the table 18, which is fast t-hereto. y

In Figure 2 three plies of web are shown at 29, 30 and 31 with carbons 32 interleaved The record-sheet is indicated at 33 as the sheet immediately in engagement with the platen, and as having one of the carbons 32 faced thereto. The web- sheets 29, 30 and 31 are shown atl their leading ends in front of the table 18; whereas the leading end 34 of the record-sheet is led under the forward edge of the table 18 and to the rear thereof.

When the platen is swung up to permit the webs to be drawn forward for the positioning of another sectionthereof, the record-sheet is clamped against the inner face of a cross-piece 35, which carries the table 18, by means of a bar 36 supported at each end by a lever 37, the levers 37 being pivoted at 38 to the swinging frame 17. The levers 37 are extended to the rear of the piv ots 38, and are then bent forward to their distal ends 39 where each carries a roller 40 adapted to bear against the nose 41 of the corresponding hook 23. Springs 42, coiled around the pivots 38 of the clamp-carrying levers 37, urge these levers in such direction as to cause the rolls 40 to bear against the noses of the hooks 23. When the arm 26 is in its Figure 2 position, with the hooks 23 in engagement with the pins 25 to hold down the swinging frame, the noses 41 of the hooks 23 prevent the springs 42 from throwing the clamping bar 36 forward to clamp the record-sheet.A When,' however, the hook-releasing arm 26 is thrown rearward to release the swinging platen-frame,

the clamp-levers 37 acting under the influence of the springs 42, follow the hooks 23, and, in so doing, rock around their pivots 38 in such manner as to cause the bar 36 to clamp and hold the record-sheet 34 against the cross-piece of the swinging frame. In order that, if desired, the clamp may be released from the record-sheet 34, whatever the position of thearm 26, there is attached to one of the clamp-levers 37 a linger-piece 43, by means of which the clamp-levers may be rockedlcounter-clockwise on their pivots 38, removing the roll from the arm 26 and removing the clamp 36 from the cross-piece35.

Referring to Figure 1, the webs 29, 30 and 31 areshown as led from supply-rolls 44, 45 and 46, respectively, revolubly mounted 0n arms 47 carried by right and left-hand standards 48 on a base-piece 49 forming a cabinet at the rear of the typewriter-stand. The base-piece 49 of the cabinet may be perforated, as at 50, to receive the rear feet of f the stand, to cause the cabinet to be properly positioned and centered with respect to the stand. The record-sheet 33 is drawn from a supply-roll 51 revolubly mounted on arms 52 projecting forwardly from theI standards 48. The webs and the record-sheet areled from their respective supply-rolls over a cross-rod 53 which connects the standards 48 at the top thereof. Preferably another cross-rod 54 connects the standards above the cross-piece 53. The webs and record-sheet pass loosely between the'rods 53 and 54; but the rod 54 controls the sheets in such way that the slack in the sheets is formed forward of the standards 48 instead of to the rear thereof.

The leading portion of the record-sheet, indicated in Figure 2 at 34 as passing backward from the platen over the table tothe rear thereof, is shown in Figure 1 as dropping rearward to the floor at 55, where it may be allowed to accumulate. This leading end is, however, finally connected to a .pickup roll Y56 revolubly mounted at 57 on arms 58 carried by and projecting rearward from the standards 48 below the web supply-rolls.

For rotating the pick-up roll'56 as and whenever desired, to gather up the accumulated record-sheet, there is pivotally mounted on the aXle 57 of the piclcup roll an arm 59 which carries a pawl 60. urged by a spring 60a, into engagement with a ratchet? wheel 61 fast to the axle of the pick-up may operate with his foot. Upon each de pression of the pedal 68, the pawl and ratchet (iO-6l, acting on the pick-up roll, effects a partial rotation of that roll; and, after each depression of the pedal, a spring 69, attached at one end to the arm of the bell-crank lever and at its other endv to the cabinet base-piece 49, returns the pedal and the pawl-carrying arm 59 to normal positions. A leaf-spring 70, secured at 71 to one of the arms 58 which support the record-sheet pick-up roll, bears against the face of one of the disks or end plates of the pickup roll to serve as a brake to prevent the overthrow of the roll under the action of the foot device, and to prevent rotation of the roll in the other direction, such as would unwra-p the record-sheet therefrom.

In the structure hereinbefore described, it is the typewritten portion of the recordsheet to which the pick-up device is applied. It is obvious, however, that the pick-up device might be used for any webrfed to and.

from the platen. For instance, instead of severing the individual forms from the webs 29, 30 and 8l, after the same have been typewritten, these webs might be fed unbroken to a pick-up device such as shown, which latter would then serve as a store until such time as it might be desired to sever and use the individual forms.

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