TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 496,295, dated April 25, 1893.

Application fled November 21,1892. Serial No.452,606. (No model.)

Tall whom it may concer-n.-

Be it known that I, FRANK L. CLIFFORD, a citizen of the United States, residing at Brooklyn, county of Kings, State of New York, have invented certainnew and useful Improvements in Type-Writing Machines, of which the following is a specification.

The object of my invention is to make provision in a simple and effective manner for the use of roll paper instead of paper in separate sheets on a typewriter. To this end, I mount a roll of paper immediately on the carriage frame of a typewriter and immediately beneath the roll IL arrange a platen preferably in the form of a stationary bar under and against which the paper is drawn by feed rollers as hereinafter described.

Referring to the accompanying drawings which form a part of this specificationz-Figure I is a topview of a paper carriage embodying my invention. Fig. II isan end View thereof. Fig. III is a transverse sectional view thereof on the plane indicated by the line III-III, Fig. I.

1 may represent the ordinary or any preferred construction of paper carriage such for example as is used on the Remington or Caligraph machines. It consists of a rectangular frame in which usually the rotary platen and paper feeding devices are lolated. In applying my invention to such a frame, I remove the ordinary paper supporting and feeding. devices and the ordinary large rotary paper cylinder or platen.

I mount in the frame a shaft 2 which is supported in any Way in the bearing 3 so as to be capable of ready removal therefrom; for instance, it can be arranged to be drawn out from the end of the carriage frame for the purpose ot' placing thereon a roll of paper 4. Immediately under the shaft 2, I arrange a platen or anvil 5 adapted to receive the stroke of the type and the paper from the roll 4 is passed under'the said platen in the manner shown in Figs. II and III. The platen 5 may be of any preferred form and be mounted in any preferred manner on the frame l. I prefer to make it in the form of a stationary bar as here shown.

In starting the paper, it is passed Vunder the bar 5 and up between the two feed rollers 6 arranged in close proximity to each other in coated with somematerial such as rubberA whereby a firm grip may be maintained on the `paper when once its end has been placed between the said rolls.

Immediately over the rolls 6, I arrange a bar or knife 7 which extends from end to end of the frame 1 and is rigidly fixed thereto. The rear edge of the bar 7 is sharpened. By this means the paper can be torn straight across the machine for removal of a strip of the desired length. The rolls 6 have fixed to their trunnions or shafts, pinions 8 which mesh with the idle pinion 8a gearing with the toothed Wheel 9 which runs loosely on the shaft 2 or on a stud or other projection lO from the frame 1. Fixed to the wheel 9 is a ratchet wheel 11 with which the ordinary ratchet feed lever (not shown) is adapted to engage to operate the wheel 9. The operation of the wheel 9 transmitted tothe pinions 8 feeds the rolls 6 and so draws the paper off of the paper roll 4 land under the platen 5 as required for the line to line feed paper. Y

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent- 1. In combination with the frame ofa typewriter paper carriage, a paper roll mounted directly thereon, a stationary printing platen located beneath the roll, a paper feed device beyond the paper roll, and stationary platen, and a severing-knife rigidly secured to the paper carriage above the feeding device, substantially as set forth.

2. The combination of the frame l, the shaft 2 adapted to carry a paper roll, the printing platen also mounted on said frame below the paper roll, the paper feed rolls 6, means for transmitting motion to the paper roll and the paper feed rolls consisting of the ratchet feeding device secured to the shaft 2, and the toothed wheel 9 loosely mounted on said shaft, the pinions 8 on therolls 6 and the idle pinion 8a meshing with the Wheel 9 and the pinions 8 on the paper feed rolls, substantially as and for the purposes set forth.

FRANK L. CLIFFORD.
