TO ALL WHOM IT MAY CONCERN:

Be it known that we, SAMUEL L. MYERS and GEORGE WILLISON, of Massil'lon, in the county of Stark, and

State-of Ohio, have invented a new and improved Smoothing and Polishing Machine; and we do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being bad to the accompanying drawings, forming part of this specification. This invention relates to a machine by which boards and wood-work, of whatever descriptidn, may be nicely polished and smoothed. Our machine is also provided with an apparatus for holding and feeding to the polishing surface such articles as spokes for wagon-wheels, &c. I

Our invention consists, first, in the construction and arrangement of a horizontal polishing-wheel, which is made elastic and covered with sand or some other polishing material. This wheel is made concave in the centre, for the purpose of smoothing the throats or hollows near the shoulder of spokes; second, in the spoke attachment, and in the manner of securing the same to the main frame of the machine, so that a vibrating motion may he imparted to the attachment; third, in the manner of polishing spokes and similar articles. To the same-is imparted a combined revolving, vibrating, and reciprocating motion, whereby the article is completely smoothed in every respect.

Having described the nature of our invention, we will now proceed to describe its construction and operation, reference being had to the annexed drawing, in whieh- Figure 1 represents a plan or top view of our improved smoothing and polishing machine. Figure 2 is a front elevation of the same. I D Figure 3 is a vertical section of the same, taken on the line a; :r, fig. 2.

Similar letters of reference indicate like parts. i Y

A represcntsa frame, which may be made of any convenient form, and of wood, or any other suitable material. 13 is a vertical shaft, to which is attached, either permanently or in such a manner as to be taken 0H and replaced conveniently, the wheel 0, the surface of which is made elastic by being cushioned with anysuitable material, the centre being made concave, as shown, (fig. The surface of the wheel is covered with sand, or any other suitable substance that may be applicable for smoothing or polishing. D is a board, which is attached to the main frame A by a bolt or pin, d, in such a manner as to be made to vibrate by means of the treadle E, and spiral spring F. Gris a sliding-shaft, provided with arms, H H, and supported by the upright braces II, which are secured to the board D. In the end of the arm H is secured a spindle, provided at one end with the chuck K, for holding the spoke, and at the other end with a orank, L, by which a rotary motion is imparted to the chuck and spoke. v i

The operation is as follows: The spoke is held by the chuck K, and by the arm H, (as shown byt'red lines in figs. 1 and The wheel 0 is revolved byaineans of a belt passing around a pulley, M, on the shaft B. By

now and then pressing downvthe tr'eadle, a vibrating motion is imparted to the board D, and with it to the spoke, eve'ry portion of which is thereby gradually brought against the polishingsurface of the wheels A reciprocating motion maybe imparted to the spoke by now and then moving the crank L forward and backward, and by turning the latter arotating mot'rorrifil'so given to the spoke. This combination of movements insures a complete and good polish to the article. By removing the spoke attachment, which is done by taking out the bolt d, the wheel 0 may he used for smoothing or polishing any other kind of work.

What we claim as new, and desire to secure by Letters Pa tent, is-

1. The board D, pivoted at d to the frame A, and having the braces I I, sliding-shaft G, with arms H H,

the latter bearing the chuck K, and crank L,.when-all are constructed and arranged in such a manner that the operator may, when desired, impart a combined revolving, vibrating, reciprocating motion to the spoke, substantially as herein set forth. v

2. The concave horizontal table C,*covered with an elastic cushion, upon which the polishing material is placed, when constructed and operating as herein set forth, for the purpose specified.

I SAMUEL L. MYERS,

GEORGE WILLISON.
