Specification of Letters Patent.

Patented Apr. 11, 1922.

Original application filed Juvne 19, 1919, Serial No. 305,237. Divided and this application filed February 18, 1921. -Seria1 No. 446,054.

2 10 all whom it may concern.'

Be it known that I, yJnssn A.`B. SMITH, a citizen of the United States, residing at Stamford, in the county of F aireld and VState of Connecticut, have invented certain chines, and particularly to means to facilitate the insertion of a work-sheet from the 'rear of the platen; and is a division of my application No. 305,237, filed June 19, 1919, (now Patent No. 1,377 ,4416, granted May io/ei.)

Heretofore, di'liiculty has' been experienced in inserting a work-sheet from the rear over a pack of sheets held in the machine, especially when the bottom ends of the pack of sheets are near the bottom of the papertable and a short distance from the rear feed-rolls.

To overcome the above-mentioned dithculty, the outer sheet of the pack, which may be a carbon-sheet, may be made longer to form a tab, which projects beyond the bottom edges of the rest of the sheets, so that the tab may lie against the rearpaper-table when the bottom edges of the other sheets are near the rear feed-rolls. Vhen the additional work-sheet is to be inserted around the pack in the machine, the typist lifts the tab away from the paper-table and inserts the sheet behind said tab; the tab thus serving to guide the work-sheet past the edges of the other sheets, after which it may be moved around the platen between the papertable and the pack of work-sheets to the printing point.

Other features and advantages will hereinafter appear.

In the accompanying drawings,

Figure 1 is a sectional side view of a typewriter carriage, illustrating the utility of the invention. Y

Figure 2 is a perspective View, showing the relationship of the Various sheets.

The invention is herein illustrated in connection with an Underwood typewriter carriage, which comprises a platen 1 journaled by its axle 2 in end plates 3 of the platenframe, which forms part of the carriage 5, and in which it is adapted to be rotated in the usual manner.

A proof or record-sheet 8 may be joined atthe leading end by means of clips 9 to a carbon-sheet 10 of the width of a memorandum sheet 11. The carbon-sheet 1() and proof-sheet S are passed together over the usual paper-table 12, between the usual adjustable edge-gages 13, to the rear feed-rolls 14, from which they pass forwardly and upwardly, past the front feed-rolls 15 to the printing line. Before reaching the printing llne, the leading edges 17 may engage paperfingers 18, which extend down almost to the feed-rolls 15, and tend to guide the record or proof-sheet to the rear of a paper-chute 19 held in front and above the platen.

'Ihe chute 19 may exert a slight pressure by its lower edge against the pack of sheets comprising the record-sheet 8 and the carbon 10 to assist in holding said pack against sliding on the platen 1, thus permitting the feed- rolls 14 and 15 to be cast off by the usual actuating handle Y(not shown). The memorandum sheet may then be inserted around the platen on the outside of the pack. Usually, one entry is made on the memorandum sheet 11, after which it may be removed and another memorandum sheet inserted around the platen. In this way the entries made on the various memorandum sheets are copied on the record-sheet.

To prevent interference of the leading edge of the memorandum sheet when inserting the latter, which may be obstructed by the bottom edges of the pack of sheets in the machine when said edges are between the platen and the paper-table, the bottom edge ofthe outer sheet of the pack is extended so as to form a tab 20, which may lie in a convenient place to be lifted away from the table 12 by the typist, so that the memorandum sheet may be inserted behind it and Slidden down over the paper-table 12 and the feed- rolls 14 and 15 to the printing point and the chute 19, which locates the memorandum sheet crosswise of the record-sheet. After the memorandum sheet has been adj usted relatively to the record-sheet, the feedrolls may be thrown against the platen to hold the sheets while-typeing. It will be understood that the Iplaten may be linespaced if more than one entry is to be made.

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

Having thus described my invention, I claim:

vl. In combination, a record-sheet to re-l eeive carbon impressions in a typewriting machine, a carbon-sheet, means to fasten said sheets together at their leading portions, and a tab, extending to the rear from said carbon-sheet beyond the end of said recordsheet, of sufficient dimensions to be convenient to grasp, to assist in introducing a Worksheet around said record-sheet.

Q. In combination, a record-sheet, a oarbon-sheet, means to fasten said carbon-sheet
