Description
EUGENE L. NORTON, OF CHARLESTOWN, MASSACHUSETTS.
MACHINE FOR FIGURING- AND POLISHING MOROCCO.
Specification of Letters Patent No. 14,821, dated May 6, 1856.
To all rwhom t may concern:
Be it known that I, EUGENE L. NORTON, of Charlestown, in the county of Middlesex and State of Massachusetts, have invented a new and Improved Machine for Polishing and Figuring Morocco; and I do hereby declare the following to be a clear, full, and exact description thereof, reference being made to the accompanying drawings, forming part of this specification, on which similar letters refer to similar parts.
Figure l is an elevation and Fig. 2 a section on the line A B of Fig. l showing my improved machine.
To polish or figure. leather friction or rubbing, as well as pressure, is required. These operations are performed by hand and also by machinery, and consist in passing or rubbing a tool across the surface of the leather, at the same time pressing the tool strongly upon it, the tool having no movement except that which carries it over the leather.
The object of my invention is to secure and control any desired amount of rubbing (the pressure having been always under control) and avoid a diificulty that exist-s in the common mode of polishing, viz., catching the tool at the edges of the leather and in the irregularities or cuts therein. To accomplish these desirable objects I give the tool or roller a rotary motion on its own axis greater than it would have if left to revolve by contact only with the body to be polished.
It is evident that if the tool were left to revolve only by contact no rubbing would result, and also that if the tool is rotated with greater velocity than is due to such Contact the amount of rubbing will be proportioned to the excess of rotation over that due to rolling; it will also be evident that when the tool is rotated in the direction which Contact would give, but with a velocity above that due to that cause, a tendency will exist to draw the leather under the tool, thus causing the tool to ride up on the leather at the edges &c. instead of catching against them.
To enable others to make and use my invent-ion I will proceed to describe its construction and operation.
The frame (O) supports the table (D) polishing bed (E) slide (F) and pulleys (G) and (I-I). The band (I) passes over the pulleys (G) and (I-I) and is secured at each end to the cross-head; by rotating the pulley (G) in each direction the cross-head is reciprocated on the slide. The tool or roller (J), mounted in suitable bearings in the cross head, has on its arbor a pulley (L) around which the cord (O) passes having its ends secured to the frame; it is evident that the reciprocation of the crosshead will cause the cord (O) to rotate the tool, and that the amount of rotation will be ixed by the size of the pulley. The bed (E) being mount-ed 0n springs yields and allows the tool to pass over leather of unequal thickness.
The leather is subjected to the action of the tool in its reciprocations by being fed from the table (D) over the bed by means of mechanism which is not necessary to refer to, as it forms no part of my invent-ion.
lWhat I claim, as my invention and desire to secure by Letters Patent, is-
The rotating tool, for polishing or figuring leather, when such tool has imparted to it a greater velocity than that due to rolling simply in the manner and for the purpose specified.
EUGENE L. NORTON.
