Specification of Letters Patent.

Patented Feb. 16, 11915..

Application filed February 12, 1912, Serial No. 677,021. Renewed February 3, 1914. Serial No. 816,335.

To all whom it may concern:

- Be it known that I, ARTHUR H. ADAMS, a citizen of the United States, residing at Sparkill, in the county of Rockland and- State of New York, have invented a certain new and useful Improvement in Printing- Machines, of which the following is a full, clear, concise, and exact description.

This invention relates to printing machines and. its object is to provide improved mechanism for automatically and continuously supplying to a laterally movable carriage the paper or other medium to be printed upon, in such a way as to avoid distorting or tearing it. To this end a roller holder for the paper is arranged to coiiperate with the laterally movable paper carriage of a printing machine insuch a manner that the paper to be printed upon is fed from the roll holder directly to the carriage, without the use of intermediate twisting members, the

paper strip being given a single partial twist over itself and at approximately ninety degrees, so as to approach .the carriage at substantially a right angle, whatever the position of the carriage may be.

Preferably the roll holder is located below the printing platen in a vertical position and pivoted at its upper end. -A particularly convenient and simple pivotal mounting is provided by making the roll holder tubular with a closed upper end, which rests in a point center bearing upon the end ofa vertical standard or support extending up through the tube.

In the drawings-Figure 1 is a view showing in front elevation the platen of a typewriting machine and the position the vertical roll holder occupies with respect thereto. Fig. 2 is a sectional elevation of the roll holder. 7

Located in any convenient position adjacent to and preferably,although not necessarily, below the machine is a support 10 ear rying an uprightrod 11 in a plane substan-. tially perpendicular to the axis of the paper carriage roll 17. A tube 12 is provided to which is fastened a plug 13. This plug 13 is countersunk at its center as shown in Fig.

Integral with, or fastened to the tube 12 in any convenient manner, is a dished plate or supporting member 14. The roll of paper is slipped over the tube 12 and rests on the dished plate 14:. The end of the paper is carried under a guard 16 of a movable paper carriage 20. The carriage 20 is provided with wheels 22 which rest on a track 23 along which the carriage is adapted to move. 4

having a square opening therein. through which a square shaft 30 extends. The shaft 30 receives motion from any suitable source of power through a gear wheel 31, and it is apparent that such rotary motion is im' parted to the toothed wheel 21 and that the paper may thus be moved from line to line as required.

In the operation of the device, the paper is fed from the roll and twisted at approximately a right angle'toward the front and upwardly, or over itself, as shown at 18, the end of the paper beingthen carried under the guard 16 across the face of the platen and over the roll 17 When the paper is fed by the printer from the roll 15 the force is V exerted along the right-han margin of the strip to the more distant edge or bottom of the roll 15 regardless of the location of the toothed wheel 21. As the carriage 20 moves laterally of the machine, the angle of the warp. The paper, therefore, always feeds to the carriage 20 on a line approximately at right angles to thetransverse line of travel thereof, without having to be guided in the proper direction by intermediate twisting members, and consequently the tendency of the paper to buckle is greatly lessened and the construction is simplified.

The center of gravity of the roll being below'the pivot, the mass of paper is balanced,

and'as the paper is fed through the'printing' machine, itunrolls freely and with practi cally no friction, all tendency of the paper to break, twist or warp, due to the quick movement of the feeding mechanism, and the lateral movement of the paper carriage, being thereby avoided. The roll being balanced and rotating in its-center of gravity,

there is no tendency on the part of the roll to rewind, as would be the case were the roll swung on a horizontal axis.

The invention claimed is:

1.- In a printing machine, the combination with a laterally movable paper carriage of a rotatably mounted rolled strip of paper adjacent thereto, the paper strip being passed from said roll immediately to said carria e by a single partial free twist of the strip over itself and at. approximately a right angle, whereby the use of guides for the paper between the roll and carriage is avoided.

2. The combination with a printing machine having a horizontallymovable paper carriage, of a paper roll holder rotatably mounted .on a vertical axis underneath the machine.

3. In a printing machine, the combination of a laterally movable paper carriage, and a paper roll holder comprising a vertically disposed support, a tubular member encircling said support and pivotally mounted thereon, and a supporting member mounted on-the tubular member.

4. In a printing machine, the combination ofa laterally movable paper carriage, a paper roll holder? comprising a support, rotatable means encircling said support and having at one end a bearing member, and a supporting member mounted on said rotatable member at the end remote from said bearing member.

5. In a printing machine, a laterally movable paper carriage, means for moving the paper across the face of the carriage, in combination with a support vertically disposed with respect to the machine, a paper roll holder pivotally mountedon said support and having a dished supporting plate, whereby. the paper may be fed across the paper carriage without tendency to twist or warp.

In witness whereof I hereunto subscribe my name this 9th day of Feb. A. D., 1912. ARTHUR H. ADAMS. Witnesses:

WALTER F. HOFFMAN, IRVING MACDONALD.
