MACHINE FOR POLISHING- BUCKLES.

Specification forming part of Letters Patent No. 14,683, dated April 8, 1856; Ressued May 12, 1868, No. 2,927.

T all fui/wm t may concern Be it known that I, ROBERT G. PINE, of Sing Sing, in the county of Westchester and State of New York, have invented a new and improved machine for polishing buckles and other articles constructed of metal, the outer or face sides of which are only polished; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure 1, is a transverse vertical section of my improvement, as, Fig. 2, showing the plane of section. Fig. 2, is a plan or top view of ditto.

Similar letters of reference indicate corresponding parts in the two figures.

My invention consists in securing buckles or other articles in clamps which are attached to rotating shafts working in yielding or elastic bearings, said shafts being placed at each side of a polishing wheel and guide wheels, so that the work or articles to be polished will be properly presented to the polishing wheel. The shafts, while rot-ating, are moved longitudinally, so that the whole surface of the work will be presented to the polishing wheel.

To enable others, skilled in the art, to make and use my invention, I will proceed to describe its construction and operation.

A, represents a rectangular framing having a shaft B, on its upper part, said shaft having a polishing wheel C, upon it, constructed in the usual or any proper way, and guide wheels D, D, which may be constructed of hard wood or metal. The guide wheels are of the same diameter as the polishing wheel, and the three wheels are placed at equal distances apart upon t-he shaft- B.

E, E, are two shafts which are placed one at each side of the wheels C, D, D. One end of these shafts fit in sockets F, F, which work in bearings a, a,- at one side of the framing A. The sockets have each an oblong slot b, made through them, and pinsc, which pass transversely through the ends of the shafts fit in these slots b. The opposite ends of the shafts E, E, have screw threads d, d, cut on them and the screw threads work in internal threads cut in bearings e, e, on

the framing A. The bearings a, a, e, e, are allowed to slide on the framing A, and they have spiral springs f, bearing against their outer sides. On the shafts E, E, there are placed clamps F, between the ends of which, one end of the buckles A, or other articles to be polished are placed. Bars G, are also placed on the shafts, which bars serve as rests for the opposite ends of the buckles or other articles.

The shaft B, is rotated by a belt H, which passes around a pulley I, on the shaft B, and also around a pulley J, on a shaft J at the lower partk of the framing. The shafts E, E, have each a pulley K, at one end, around which a belt L passes, said belt also passing around a pulley M, on the shaft J The operation is as follows. Motion is given the shaft J in any proper manner and the shafts E, E, B, are rotated by their respective belts L, H. The spiral springs f, keeping the face of the buckles A', against the periphery of the polishing wheel C, and the guide wheels D, D, preventing the buckles from bearing too hard against the polishing wheel. Were the guide wheels not employed the polishing wheel would be liable to cut or wear off the sharp corners of the buckles. As the shafts E, E, rotate, they gradually move longitudinally in consequence of the screw threads cl, eZ, working in the threads in the bearings e, e, and consequently, t-he whole outer or face sides of the buckles will be polished.

It will be understood that the articles being polished, must be all of the same form, that is, those that are polished at the same time, in order that the articles which bear against the guide wheels may cause the article which bears against the polishing wheel to be properly presented to it.

Any proper number of polishing and guide wheelsl may be employed and the shafts E, E, may be of such a length that a large number of articles may be ,polished at the same time. When the articles are polished, the shafts E, E, are moved back by means of a crank.

rlhe above machine will polish rapidly and well, and is therefore a labor-saving machine. It will be extremely valuable in manufactores Where many articles are now I longitudinally moving shafts E, E, provided polished by hand, or by the slow process of with clamps F', the shafts E, E, Working 1n l0 an ordinary polishing Wheel. yielding or elastic bearings substantially as Having thus described my invention, shown for the purpose specified. 5 what I claim as new and desire to secure by ROBERT Gr.
