Patented Sept. 8, 1931 UNITED STATES PATENT OFFICE v FRED BECKER, 0F BUFFALO, NEW YORK, ASSIGNOR TO UNDERWOOD ELLIOTT FISHER COMPANY, OF NEW YORK, N. A CORPORATION OF DELAWARE TYPEWRITING MACHIN E Application filed November 14, 1927. Serial No. 233,057.

'I his invention relates to papen-handling devices on typewriting machines, and particularly to improvements on paper-tables such as are being used on standard machines for the purpose of feeding superimposed work-sheets from independent sources, said tables being employed concurrently, and the sheets from one table being superimposed at' or near the platen upon the sheetJor sheets from the other table. v

The occasion for such independent feed of work-sheets to the plate'nlarises, for stance, where it is desired to u'se and to retain in the machine a record-sheet on which to acand carbon in place, i. e., securely hugged cumulate the entries made on a successionlof individual bill or statementsheets; To this end, two tables, one in back of the other and downwardly converging towards the platen, are provided at the rear of the platen. A relatively wide and long record-sheet assembled with a carbon from the forward table, and an individual narrower and shorter statement-sheet from the rearmost tablepare p0- sitioned and fed around the platen for writ; in g. After passing the typing line, the sheets may be separately delivered by sultable means. 1

A usual set of pressure feed-rolls may be released in order to remove a written statement, while other means are effective to iiidependently hold the combined record-sheet around the platen, so that another statements sheet may be inserted at the rear, and freely positioned for another entry upon the recordsheet.

With normal construction of the papertables the large ends of the record-sheet will rearwardly overhang the paper-tables, and are liable to interfere with convenient and quick insertion of the small statement sheets, and to cause the record-sheet to be torn or soiled. It furthermore is troublesome to insert properly a plurality of sheets having a length as great as said record-sheet.

To overcome these objections a feature of the invention provides, in conjunction with the conventional paper-guides extending in back and around the lower part of the platen, a second or auxiliary paper-table which carries atthe top a receptacle or tube-member to receive therein a rolled-up record-sheet, which, through a slit-like opening, may be led downwardly upon the table, and, together with the'statement-sheet, or the like, supplied from the rear paper-guide, be fed around the platen, as indicated above. Evidently, this compact arrangement will not only allow convenient and unobstructed insertion of the individual statement-sheets at the rear, and offer full protection to the recordsheet, but, due to the record-roll being easilyfpositioned within the tube relatively to the platen, it will expedite the proper insert1on of its leading edges under the platen.

Another featuretakescare of the delivery "end of the recordsheet by leading the same upwardly and rearwardlythrough a narrow chute from adjacent the typing line tangentially into another tubular-shaped container.

The rotating platen, therefore, will draw the paper from the rearward tube. causing it to unrollp while pushing the leading edge through said chute into the second or frontt-ube and'in-to roll-form again. The statement-sheetf'however, may be caused to separate fromthe record-sheet when the. former is being brought to pass a special deflectorplate or collating table in front of saidc-hute.

In the preferred embodiment of the invention, the rear as well as thefront tubular memberv are endwise combined upon brackets to make them a unit shaped for ready attachment to standard machines Each of said record-holding parts again is preferably bent out of a single piece ofsheet-metat and mounted upon said brackets by screw-andslot connections for proper adjustment rela tively to and for co-operation with the platen.

Other features and advantages will here inafter appear.

In the accompanying drawings,

-Figure 1 is a cross-sectional elevation, showing the novel auxiliary table being attached to the carriage-frame of an Underwood machine and being formed with a tubular record-sheetholder integral with a forwardcollating table for paper-deliverv.

Figure 2 shows, in addition to said auxiltill iary table of Figure 1, a similar tubular sheetmetal structure to receive the delivery end of the record-sheet.

Figure 3 is a top view and guiding elements, from Figure 2.

Figure 4: is a fractional perspective of detached parts, showing therecord-handling elements, and more clearly constructive details.

A carriage-frame of an Underwood typewriter includes side plates 10, which carry journaled therein the shaft 11 of a platen 12, said shaft terminating in usual finger-wheels 13 for platen-rotation. A type-bar 14 in printing position, indicates the front of the platen. The side plates are shown to,be.connected by a usual paper-guide or apron 15 extending back of the platen and around the lower part thereof. For special operation of the machine, such as herein intended, the apron will serve to feed a succession of individual statement-sheets or bills to the platen, which are to be duplicated upon a continuous strip or record-sheet, which may be individually fed to the platen by means of an auxiliary paper-table, 16, which extends in front of said apron 15 and also at the rear of the platen. The auxiliary table is made from sheet-metal, its upper end being curved to form a tubular secti0n'17, which is to receive a rolled-up record-sheet 18, together with an assembled carbon-sheet 19. The circular curve of the tubular section 17 does not close up entirely against the auxiliary table, but leaves a clearance 20 to permit the record-sheet and carbon to be passed downward ly upon the table to join for combined feed around the platen, a statement-sheet 21 coming down from the rearward table, upon which it may be positioned by a usual side gage 21. The pack of sheets is advanced by means of usual feed-rolls 22 co-operating with the rotating platen, and, after leaving the guidance of the apron 15, is passed across the typing line under the control of further guiding means presently to be described. a

The delivery end of the record sheet or sheets is thus guided from the apron across the typing line to enter a narrow chute 23 thereabove, said chute being made of sheetmetal to tangentially join into a record-receiving sheet-metal tube 24 with which it may he integrally built. In the course of operation, the record-sheet is pushed through said chute upwardly into said receiving chute to be loosely rolled up again, while the individual statement-sheet is separated from the recordsheet at the chute-intake when it is forwardly deflected by a deflector-plate or collating table 25, the latter preferably also formed inteof the paper-feeding substantially taken gral with the sheet-metal chute. The above-' mentioned means to guide the paper across the typin line includes a mechanism 26 having movable paper-fingers, as usually found in the Underwood machine and shown effective in Figure 2 of the drawings. A rod 27, longitudinally of the platen-axis and a suit able distance rearwardly upwardly from the platen, is mounted in the side plates 10. Two arms 28 are swingably as well as longitudinally-slidably mounted upon said rod. Each arm has at its forward end a laterally-bentover tab 28 to carry screwed thereon a paperfinger 29. The paper-finger, substantially following the curvature of the platen-circumference, extends forwardly and downwardly to proximity with the forward edge of the apron and slightly overlaps the same. The paper-finger, adjacent its upper part, has turned-up lateral ears 30 to carry journaled therein a guide-roll 31, which, through an opening in the paper-finger, contacts with the laten-surface to aid in properly conducting the paper thereon, and is resiliently held in effective position by a detent pin or member 32 provided in the rear end of said' arm, said detent-member engaging in a groove 33 extending in and along the lower side of said rod 27. The tab 28 of said arm 28 may be formed with a curved part 34, to serve as a finger-piece for upward, swinging movement of the paper-fingers, that is, for movement to ineffective position (not indicated), thereby urging the detent-pin out of said groove, The paper-fingers are laterally slidable upon said rod and set for marginal enagement of the relatively-wide record-sheet. t the center part of the platen is frhctionally indicated an arm 35, also known from the Underwood machine as being resiliently mounted upon the carriage-frame, and at its free end carrying a roller 36 to engage the platen for paper-guidance slightly above the typing line. This roller-carrying arm, which, in general, is also swingable away from the platen, serves, in the present operation of the machine, to locate the narrower statement-sheet, which is not gripped by the paperfingers on its way beyond the typing line.

Following more closely the path of the work-sheets, it will be noted that the rolledup record-sheet is located within the tube by a side gage 37 which, by screw-and-slot connection 38, 1S adjustably mounted thereon.

The ends of the tubes are beveled, so that the ends of the record-sheet may partly project out of the tube-ends to allow the operator to watch the rolling and un'rolling of the sheets and to conveniently handle the same. The lower end of the auxiliary table is formed with a lip '39 extending into close proximity with the rear of the platen and effective to exert a permanent drag upon the record-sheet as the same is advanced upon the rotating platen, and to support the record-sheet out of the path of the sheet on the rcarmost table. This lip 39 at the rear, in conjunction with the paper-fingers in front of the platen, serves to keep the record-sheet closely hugged enemas around a large part of the platen-circumference. Therefore, when the lower feedrolls' are released, the record-sheet will not shift upon the platen nor interfere with a statement-sheet when'the same is loosely inserted and aligned after a written statement is removed. It will also beunderstood that, with proper construction of the tubes, the record-sheet, except for acertain amount of friction which may be kept within proper limits, is not subjected to any'injurious strain when moving through the machine, this being due to the absence of moving masses, as spools, or the like, connected to the paper.

Essential for proper operation of'the novel record-holding device is its adjustable mounting upon the platen-carriage. From Figure 3 it will be seen that both tube-members have longitudinal extension-strapsl w and 41 respectively) at either end, by means of which theyare end wise combined and mounted upon brackets 41 of sheet-metal, both tube-members thus becoming a unit, which may be readily attached and adjusted to standard machines, as will be presently seen. Each bracket includes a body-strap 42, which is flatly mounted on a horizontal flange 43 at the top of the side plate 10; Eachstrap has a; screws passing slot 44 at either end, and 't-herethrough and threadinginto said flange of theside plate, so as to be adjustable transversely to the platen-axis. Each strap, furthermore, is integrallyformed *with a depending arm 45 and a rising arm,46, to support the rear and front tube-members respectively. The depending arm has a flange 47, which offers a forwardly and downwardly,

inclined surface, upon which to support the rear tube-member or auxiliary paper-table 16 by a double slot-and-screw connection 48, which allows adjustment ofsaid paper-table upwardly or downwardly on the slope, in such a manner as to control the clearance between the lip 39 and theplaten-,

surface, according to varying thicknesses of the record sheet or sheets. The front tubemember or chute 18 supported in a similar way, that is, by a single slotand-screw con nection 49 upon said rising member 46.

Figure l, as a modification, shows the principle of the novel device by only providing one paper-holding tube 50 upon the auxiliary paper-table, said tube being integrally formed with a plate 51 to serve as a collating table or shelf for the delivery end of the sheets. a

It will be noted that the two web-containers are an assembled unit to be secured to the carriage-ends as a unit of mechanism; that the supply-roll container 17 is open at both ends, has a web-protecting wall at the rear thereof, and one or both front corners of the eontainer are cut off or beveled forwardly to expose the edges of the web and disclose at a glance the amount of web remaining in the auxiliary said tally-strip in 1 -while the feed-rols are released gtoI allow an original work-sheetto be loosely posisupply container; that "the web-receiving container is similarly beveled ofi at one or both corners to afford a finger-hold for gripping the rolled-up typed web and its carbon, for withdrawing the typed web from its container; that the supply-roll may be inserted through one open end of the container 17 and thrust therethrough against the web-locating stop 37 at the opposite end of the container by the pressure of the finger against the ex-' posed edge of the roll; that the narrow chute 23 extends, without interruption between the face of the platen and the container 24; that the chute'23 is open at both ends; that the two parallel avails of the chute prevent buckling of the platen-fed web between the platen and the container, which renders'the .web self-winding within the container; that Having thus described my invention; I
