UNITED STATES 'PATENT OFFICE.
ARTHUR K. THYLL, von lNEW YORK, N. Y., vAssIeNoR To THE ELECTRIC CUTTER COMPANY, or SAME PLACE.v
CLOTH-CUTTING MACHINE.
SPECIFICATION forming part of Letters Patent No. 511,562, dated December 26,1893'.
Application tiled March 14,1893. Serial No. 45663002.f (Nnmodel.)
To all whom t may concern:
Be it known that I, ARTHUR K. THYLL, a subject of the Emperor of Austria-Hungary, and a resident of the city of New York, county of New York, and State of New York, have invented certain new and useful Improvements in Electric Cloth-Cutting Machines, of which the following is a specification.
My invention has reference to improve-4 ro .mentsin cloth-cutting machines but more particularly to that class of cutting machines designed for cutting cloth or other fabrics, in which an electric motor is mounted'upon and carried by the machine for operating a round knife. V
The prime object of this invention is to enable said machine to cut above the center of the circular knife, so as to make it possible to use a comparatively small knife for cutting a high pile of cloth. v
'Another objectief this improvement is to lessen the friction created on the sides of the disk knife in traveling and rotating through said cloth or other fabrics, so as to use as little power as possible for cuttingthe same.
In the accompanying drawings Figure l, representsa longitudinal section and partly a side view of my electric cloth-cutter. Fig.
` 2, is a front view and partly a cross section 3o of the same. Figs. 3, and ,4, are special views of the'base thickening device and knife protector.
Similar letters of reference indicate corresponding parts.
My invention is applicable to cutting machines of any character, but is more especially adapted and is herein illustrated in connection with a type of over board cloth-cutting machines, so called because of its being moved around by hand over the work table when in operation, the power for operating themachine being derived from some suitable source, such as an electric motor, mounted upon and carried by the machine, or flexible shafting, or some similar device.v

Referring by letter to the accompanying drawings, A indicates a base having a flat circular shape and if desired mounted upon antifriction rollers (not shown), and B indicates 5o a standard, cast or secured in any other way to the base A, near the 'center of the same,
supporting upon its upper end a plate or bed C, carrying the working parts of the machine. Whenthe machine is electrically-operated one or two motors D D are mounted upon said plate, the armature shafts E E', of which, are journaled on one end in bearings F F projecting up over the top of the plate C. On their inner ends said armature shafts E E are coupled and carry a sprocket wheel G, 6o having side plates g g', said plates keeping a link chain H in its position in running over said sprocket wheel G. The standard B has around its center, a circular recess, which recess is upwardly extending to the top of the standard. This recess contains a second Asprocket wheel G fastened to the circular shaped knife I. Knife and sprocket wheel are loosely fitted to a pin K screwed into the standard B. Chain H runs over the two 7o sprocket wheels G G', thus imparting the rotary motion of the armature shafts to the disk shaped knife. The standard B, also carries an extension L, to which a suitable handle M, is fastened'. A steel hardened piece N is 75 mounted upon the base A, having upwardly extending ,projections n 'a' at the sides of the rotary circular knife and being shaped according to lthe periphery of the same. The steel piece N is of suflicient thickness to cover 8o atleast one quarter of `the circumference of` the knife. The application ofthis device will prevent the self feeding of the rotating knifeand also protectthe sides ofv the same from any unnecessary friction in cutting cloth. A switch for starting and stopping the electric motoris mounted upon a suitable place of Said cutting machine.
Having thus described my invention, I claim as new vand desire to secure by Letters 9o Patent* l. In a cloth cutting machine the combination with a movable base, of a standard mounted upony the same and carrying on its upper end a supporting plate, two electric motors fastened to the said plate, a sprocket wheel having two side plates for guidinga chain on said sprocketwheel, which is keyed to the armature shafts of themotors,a rotary knife journaled in the standard, a second loo sprocket wheel directly fastened to thejsame, and in connection with the armature shafts by means of a chain run ning,r over both sprocket wheels, substantially as set forth.
2. ,In a cloth-cutting machine the combination, with the base A, the standard B, and the rotary knife I, of the plate N attached to the base having upwardly extending projections n n at the sides ofthe rotary knife, which are shaped according to the periphery of the said knife, substantially as set forth.
3. In a cloth-cutting machine the combination with a base of a recessed standard mounted upon the same and carrying on its upper end a supporting plate, two electric motors fastened to said plate, a sprocket wheel keyed to the armature shafts of the motors and operated by the same, a rotary circular knife jonrnaled in the standard, and a second sprocket wheelfastened to said knife located in the recess of the `standard and being in connection with the upper sprocket wheel by means of a chain, substantially as set forth.
et. In a cloth cutting machine the combination of a base A, standard B having arecess b, plate C, motors D D', sprocket Wheel G with side plates gg', chain h, sprocket wheel G', knife I and pin K, substantially as set forth. In testimony that I claim the foregoing as my invention I have signed my name, in presencg of two witnesses, this 10th day of March, 189
