OF NEW YORK, N. Y., A COR- TYPEWRITING MACHINE. 7

Original application filed July 12, 1923, Serial No. 641,073. Divided and this application filed April 21, 1924. Serial No. 707,895.

To all whom it may concern:

Be it known that we, LEWIS C. MYERS, a citizen of the United States, and resident of Freeport, in the county of Nassau and State of New York, .and Gnonen F. HANDLEY, a citizen of the United States, and resident of Glendale, 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.

This application is a division of our prior application, Serial No. 641,073, filed July 12, 1923.

The machine illustrated in the parent ap plication is designed for a special class of work in which relatively narrow slips of paper are employed and wherein it is nec essary that each succeeding sheet be fed into the machine in exactly the same position and be held accurately while being written upon. Certain paper feeding devices were devised for use therewith, but are in no way limited in their applicability to the particular machine disclosed in the parent application, or to any specific type of ma chine, but have a broad field of application.

T An object of the invention is the provision of a simple and efiicient feed roll mounting wherein front and rear feed rolls are carried by the same frame and will be spring pressed against the platen in such a manner that both will engage the platen even if the thickness of the sheets varies.

Another object is the provision of a mounting for the paper table which is intimately associated with the feed roll support and is simple and efficient.

Another object is the provision of a paper table or chute having one side adjustable in order that the width thereof may be varied, while the paper table as a whole may be adjusted from side to side of the machine without varying the adjustment of the width of the chute itself.

Another object is the provision of a pa-. per holding finger at the front of the machine which will engage the paper above the printing line and from side to side of the printing point. 7

Other objects will be apparent from the following detailed description and the appended claims.

In the drawings:

Figure 1 is a front View of a carriage of a typewriting machine showing certain portions of our invention.

Figure 2 is a vertical fore-and-aft section with parts in elevation.

Figure 3 is a plan view of the paper table and feed rolls with the frame therefor, the platen being removed.

Figure 4 is a view similar to Figure 2 but on an enlarged scale.

There is illustrated a carriage having side members A and a base member B between which and a track member C are interposed ball bearings a. This track member C may be a part of the main frame, or it may be a part of the shift frame as in the case of the ordinary Royal typewriter structure. In the carriage is mounted a platen D which is illustrated as a short platen, as in the parent case, but so far as the invention herein contained is concerned, it may be of any desired length. This platen is provided with the usual or any desired line space mechanism E. The usual paper scale F and fingers G may be employed and the scale isv supported by fingers H carried by the member C. One of the fingers G is usually omitted or moved to inoperative position to permit the use of a special finger hereinafter described. These parts may be of the usual Royal construction or of any other old or desired form.

A rod 1 extends between the side plates A of the carriage and has mounted thereon arms 2 which carry a short shaft 3 in their ends. Arms t are carried on the shaft 3 inside of the arms 2 and support at their ends rear and front feed rolls 5 and 5. The shafts of these rolls are preferably mounted in open bearings in the ends of the arms 4 as shown in Figure l. Each arm is provided with an outwardly extending ear 6 to each of which is hooked one end of a spring 7 the other end of which is fastened to a pin 8 supported by the side plates A of the carriage. These springs tend to hold the feedrolls against the platen D.

A flat bar 9 which is preferably integral with the arms 2, overlies the rod 1 and suptions 13, which permit the adjustment "of this side to the dotted line position in Figure 3. By'theuse of these relatively high side portions a. deep chute is formed, the width of which may be adjusted so that the bills or'sheets upon which writing is being "done will fit snugly in the bottom thereof. Successive sheets or bills may therefore be introduced and the writing in the right.

hand column will always fall in the proper position. 7 The table 10 and sides 12 and 12' l'r'averolled edges l t to improve the appearance and facilitate the introduction of the hills into the machine.

To hold the bills snugly in the bottom 'of the chute, one of the usual paper fingers G is either oniittedor turned to inoperative 'ros'iti'on and a special finger provided. This comprises a -member 16 which is pivotally "connected to one of the arms or fingers H and is spring pressed against the platen by a sprin" 17. It extends over the printing pointa j acent to the finger G and has a cuto'ut'1'8 lying above theprinting point. An upper extension has a rolled end 19 and the lower edges 20 are outturne'd in order .that

"they may not catch on the sheets when in- -troducedf into the machine.

"It will be noted that the paper table "and chute 'c'anbe adjusted as a whole or the size 'ofthe chute Joan be varied, and that either adjustment can be made without interfering with the other. The feed rolls and tabl'ear'e pressed into position I by simple spring mechanism and the rolls are so mounted that they will always bear evenly against the platen. The special paper finger 16 holds thepaper close-1y against, above andfat'both sides of the printing point, while the scale l performs the same function below the 'printingline. The paper is therefore held smoothly at the point of printing, even if a 'stifi sheet orcard is employed. Since the scaleF and finger 16 is supported by the frame or by the shift frame'if the machine 'is so equipped, it will always bear against "the paper in the same relative position to the printing point regardless of the endwise position of 'the carriage or the case shift position.

Obviously various detail changes may be made without in any way departing from the'spirit of the invention, and it isunderstood'that the invention is to be regarded as limited only by the scope of the appended claims.
