U NITED STATES ()FFIGE:

GUSTAF SWENSON, OF PITTSBURG, PENNSYLVANIA, ASSIGNOR TO UNDERWGOD TYYE- WRITER COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW JERSEY.

TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented Oct. 25, 1910.

To all whom it may concern.

Be it known that I, GUSTAF Swanson, a citizen of the United States, residingin Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in. T yperiting Machines, of which the following is a specification. i.

This invention relates to devices usually provided at the side of a ty wwritil lg machine for engaging the side edges of the sheets as they are placed into position for writing.

Heretofore the side gage has been in the form of a. ledge turned up from the plate, the latter provided with a claw or book to fit tightly upon the rolled upper edge of the paper s'helf, such as in the well known Un- It has been found thatthese hooks or 'claws must be so tight, in order to hold the gage roperly upon the letter-feeding carriage, t at it is diflicnlt to adjust thenralong the paper shelf, owing to their strong binding action,

and moreover the shelf becomes scratched and marred.

The object of my invention is to provide for convenient and easy attachment and detachment of the gage from the paper shelf and easy adjustment therealong, without liability of marring the shelf, while the gage is held securely n position.

In the drawings forming a part of this application, Figure 1 is a sectional side elevation of the platen frame of an Under-wood typewriting machine, with my improvements applied thereto, and-Fi 2 1s a perspective view of the front of t e same, partly in section.

The usual latenl, is revolubly mounted in a lat'en rame 2, which includes an in cline paper shelf 3 in rear of the laten and forwardly from which are arms 10, preferably of elbow form and carryin at their forward ends a plate 11., bearing acewise upon the back of the paper shelf 3 and cooperating with the plate 6 to form a clip.

- One or more springs 12 are carried by the shaft 9 and have one end pressing upon the claw 7, while the other presses on some portion of the arm or arms 10, to provide moderate pressure of the plate It on one Side of the shelf and the plate (3 on the other side thereof, to hold the gage from jarring out of position during the intermittent movement of the carriage. This clamping action also keeps the plate 6 close against the shelf, to prevent the sheets of paper from getting between them; the claw 7 having a pivotal action on the tubular rim 4, to permit the spring to do this.

By extending out the contact of the clamping member, as by the bar or plate 11, the

clamping member will tend to keep the plate 6 against the shelf throughout its width, and the plate 5 at right angles to' the surface of the platen.

It is obvious that the gage may be shifted readily along the shelf to any position without scratching the surface-of the shelf, and that the gage firmly retains its position.

Having thus described my invention,

claim:

1. A device of the character described,

curved edge of said she f, and a spring pressed clip on said claw and extending forwardly to press against the'b'ack of the paper shelf, to bind said member thereto.

2. A device of the character described, comprising a member adapted to be secured to the paper shelf of a typewriter to serve as a paper gage, said member having a claw curved to conform to the rolled edge of the said shelf, ears on said claw, a-pintle mounted thereon, a plurality of downwardly and forwardly extending arms carried b said pintle, a cross plate connecting sai arms and adapted to en age against the rear of the typewriter shel to hold the gage against the front thereof, and springs to press said plate against the shelf.

3. A gage for the side edge of the sheet, to be attached to a paper shelf and having 5 a claw 0r hook to catch over the top of the l \Vitnesses:

paper shelf and support said gage ivotally MAYNE R. DENMAN, thereon, and a spring clip pivotal to said C. E. Yos'r.

claw and extending forwardly to press against the back of the paper shelf, to bind said gage thereto.

GUSTAF SWENSON.
