HARRY H. VICKERS, OF CORONA, NEW YORK, ASSIG-NOR TO UNDERWOOD TYPEWRITER COMPANY, OF NEW YORK, N. Y.,

A CORPORATION OF DELAWARE.

TYPEWJQITING MACHINE.

Application filed February 20, 1923. Serial No. 620,167.

To all whom t may concern.' v

Be it known that I, HARRY H. Vromans, a citizen of the United States, residing in Corona, Long Island, in the county of Queens and State of New York, have invented certain new and useful Improvements in Typewriting Machines, of which the following is a specification.

The invention relates to tables on the carriage of a typewriting machine for guiding work-sheets `to the platen. More particularlythe invention relates to machines in which two tables are provided, one spaced forward of the other at the rear of the platen; the tables being employed concurrently, and the sheets from one table being superposed at or Enear the platen upon the sheet or sheets from the other table. The occasion for such independent feed of worksheets to the platen ordinarily arises where it is desired to use, and to retain in the machine a record-sheet on which to accumulate the entries made on a succession of individual bill or statement sheets. In'this use of the tables, the record-sheet is fed from the forward table, and the individual statement-sheets from the rearmost table; the collation and feed of the sheets, in the machine, being explained in the pending application of Jesse A. B. Smith, Serial No. 598,066, filed October 31, 1922, now Patent No. 1,524,756, dated February 3, 1925, to which reference is made for details not herein shown.

A feature of the resent invention is the provision of means for supporting the tables for adjustment independently one of the other.

A further feature of the invention is the provision of means whereby the record sheet or sheets, on the forward table, may be supported against the platen or prevented from sagging into the path of the sheets being introduced from the platen from the rearr most table; thus allowing free and unobstructed movement under and around the platen of the sheets from the rearmost table, and preventing dragging of the stationary record-sheet by the `sheetsadvancing'from the rearmost table.

In the preferred embodiment thereof, the invention comprises means for adjusting' the forward table to bring the lower or delivery edge thereof into .such position, or close on the record-sheet when the latter is fed with, or advanced around, the platen; and thereby to cause the record-sheet, after such feed, to be held up frictionally by such lower edge, or equivalent lip, between the same and the platen, out of the way of the sheets from the othertable; this result being aided by rolls running on the record-sheet at the delivery side of the platen, and the stationary record-sheet being caused to hug 'f the stationary platen between said lip and said rolls, and hence to leave the path constantly clear for the statement to be introduced from the rear and thrust forwardly under and up around the stationary platen i vwriting machine having thereon the papertable of the present invention.

Figure 2 is a view, in side elevation, taken on the line 2 2 of Figure 1.

Figure 3 is a perspective view, showing the right-hand end of the platen-carriage and ofthe paper-table, and the bracket by means of which the table Ais adjustably mounted on the ends of the platen-carriage; the parts being separated for clearer illustration thereof.

The platen 10 is journaled by means of its axle 11 in side plates 12 of the carriage, supported, in part, by rail 13 for movement in letter-feed and return directions on the main frame 14 of the machine. The platen-shaft 11 is provided with the usual hand-wheels 14a and line-space mechanism 15"; the latter not being fully shown, but being of the kind found on the' Underwood machine.

The sideplates 12 of the platen-carriage' are connected and tied together by acrosspiece 16 at the rear of the platen, and fast t9? this @ross-piece the usual paper table toa fixed opera- Sli and apron 17, for guiding the paper around underneath the platen to the front thereof. Front and rear pressure-feed-rolls 18 and 19, respectively, are indicated below the platen. These rolls, normally bearing upon the platen, are adapted to be thrown off the platen, or released, for free movement of the paper around the platen, by mechanism not shown, but which may be of the kind found in the Underwood typewriting machine.

The rear paper-table 20 is connected at 21 to the rear table-extension of the apron 17. Connection 21 may be a pivotal connection, so that, when desired, the table 2() may be swung. To provide the pivotal connection 21, ears 22 are turned or curled out of the body of the table-extension of the apron 17, and carry pins on which ears 23, similarly turned or curled out of the body of the table, are journaled. The table 20 is, however, normally held stationary on the platen-carriage against movementon its pivot 21; and, for so holding the table 20, it is secured by thumb-screws 24, one at each side thereof, to brackets 25, in turn, secured by screws 26 to the side plates 12 of the platen-carriage.

Mounted independently on the platencarriage, forward of the table 20, is another table 27. The table 27 is secured by screws 28 to ears .29 on brackets 30, in turn, secured by screws ,31 to the side plates or ends 12 of the platen-frame or carriage. In order that the table y27 may be adjusted up and 4down on the brackets .30, it is slotted at 32 where the screws 28-pass therethrough. The screws 28 thread into the bracket-ears 29, and, when turned home, the heads of the screws vbear against the table 27 and hold the same in adjusted position. The table 27 is also adjustable forward and rearward with .respect to the platen, and, lto this end, the brackets 3() are slotted at `33 where they receive the screws 31. The screws 31 are threaded into vthe carriage-plates 12, and, when the screws are turned home, the heads thereof bear on the brackets and hold the same in adjusted position.

As fully explained in the hereinbeforementioned yapplication of Smith, the table 27 is employed as a guide and support for a record-sheet, or other sheet on which the several entries made on the individual statement-sheets, fed down over the rear table 20, are successively entered. Such a recordsheet, indicated at 34, is shown. as led between the lower end 35 of the table 27 and the platen, thence around the platen, across the printing line, and up between the platen and paper-inger-rolls 36 to the rear of a front eollating table 37. Av carbon-sheet 38 is shown as accompanying the record-sheet. To provide for free passage of the recordsheet behind the collating table and paperfinger-rolls 36, and to permit- .of adjustment Of 'the ratori-allee?, freely 0.1.1 the platen,

after completion of the entries on the individual statements, the lower end of the collating table 37 and paper-inger-rolls 36 are adapted to be swung forward. For this purpose, the collating table, which is in two sections '37a and 37b, is secured to a bail 39, fast on a rock-shaft 40, journaled in brackets 41, secured by screws 42 to the side plates 12 of the carriage. The paper-fingers which carry the rolls 36 are not shown, but may be of the structure shown in the aforesaid Smith application, and, as therein shown, are connected to the rockshaft to move therewith. Fast to the left-hand end of the shaft 40 is a finger-piece 43 by means of which .the shaft may be rocked to swing the collating table and paper-finger-rolls. The eollating table is in two sections, adjustable relatively to each other, longitudinally of the platen, by means of slots 44 and screws 45, to accommodate itself to sheets of different widths; and the sections 37n and 37b of the collating` table have flanges or side gages 46 for the papers on the eollating table.

The record-sheet table 27 is adjustable so elos'ely to the platen that the record-sheet will drag on the lower edge 35 of the table 27; the object being to prevent dropping or sagging of the stationary record-sheet away from the platen. Instead of a single sheet 34, there may be several sheets led over the table 27, and adjustment of the table, to accord to the thicknesses of paper between the edge 35 thereof and the platen` may also be required. i

The sheet or sheets 34- on the table 27 being held up, as described, by the edge 35 o-f the table, and the pressure-rolls 18 and 19 being released, the sheets on the rear table 20 may be passed freely around under the platen, unobstructed by the sheets 34, and without dragging, pushing or bulging the sheets 34 forward, and may thence be drawn to the collating table 37, and collated thereon. The steps involved in the adjustments of the record-sheets, and in the collating operation-` are well understood, and. in any event, are explained in the aforesaid Smith application.

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