POLISHING-MACHINE.

' Specification of Letters Patent.

To all whom, it may concern Be it known that I, LEWIS F. KLAY, a citizen of the United States, residing at Niagara Falls, in the'county of Niagara and State of New York, have invented new and useful Improvements in Polishing-Machines, of which the following is a specification.

chine which is more particularly designed for polishing the tines of table forks al-.

' purposes in which like conditions exist.

It is the object of this invention to provide a polishing machine for this purpose which will permit an operator to not only polish the tines of the fork without liability of cuttinghis hand but also permits this work to be done expeditiously and perfectly, and also with infrequent renewal of the polishing surface. 1

My invention has the further advantage in that a coarse and fine polishing effect can be produced successively upon thetines by the same machine, thereby enabling the p01- ishing of these goods to be effected more economically.

In the accompanying drawings: Figure 1 is a front elevation of the polishing machine embodying my improvements. Fig. 2 is a side elevation thereof. Fig. 8 is a horizontal section, on an enlarged scale, taken in line 38, Fig. '1. Similar characters of reference indicate corresponding parts throughout the several views.

1 represents the mainframe of the polishing machine which may be of any suitable construction and 2 a standard mounted on this frame and provided at its upper ends with two bearings 3 which are arranged horizontally and transversely. In these hearings 1s ournaled a horizontal transverse driving shaft or spindle 4 which may be body 6 having the form of a wheel and preferably constructed of wood although any This invention relates to a polishingmaother suitable-material may beused if desired. The marginal part of this wheel-is constructed in the form of twoiperipheral sections 7,801 different diameter 'which are arranged side by side or out ofline with Patented Sept. 9, 1913. v Applicationfiled April 16, 1913.

side of the wheel. The two peripheral *sec- 1 tions are concentric relatively to eachother and to the axis of the wheel.- Upon the rear large peripheralisection of the supporting I wheel is-mounted an annular flange, r m or band 9 which projects with its front edge beyond the frontside of the large section of this wheel and overhangs thesame; On

the small front section of the wheel is;

mounted an annular rim flange or band 10 which projects forwardly'from this wheel so as to overhang the same. .The width of the rim-of large diameter'i's suoh'tha't its front edge is in line with, or substantially so, with the rear edge of the annular rim of smalldiameter, so that both ofthese'rims are arranged out of line relatively to each other in a direction lengthwise of the axis'of rotation and the outer surfaces of the same are both exposed radially. Each of these supporting rims is preferably constructed of I metal which may be secured to the wheel by means of screwsll, as shown in Fig. 3, or by any other suitable means. On its outer side the larger rim is provided with a polishing, abrading or bufiing surface 12 and the outer side of the small supporting rim.

means of glue or otherwise. The large supporting rim is preferably provided with a polishing'or abrasive surface of coarse material while the small rim is provided with a polishing or abrasive surface of fine material.

In the operation of polishing a fork 14 the operator engages its tines successively with the abrasive surface of the large rim,

tor then engages the tines of the fork suc- I cessively with the fine abrasive surface of the small rim, whereby all scratches or other fine marks are removed from the tines and the same is finished. V-V'hile thus engaging 1 fine abrasive suriacesot the large and small .s'upportingfrims the gfiork; is. supported by the operator on the upper end of a stand 15 which arranged adjacent to the sfree edges of the supporting rims and horizontally in li ie with the axis of rotation thereof and *moun-ted o the adjacent part of the frame.

This machine is exceedingly simple in construction, the same can be produced at lQW cost, is not liable to get out of order and it can be operated with a small expenditure of power.

I claim as my invention:

1 A polishing machin comprising a rotatable wheel, and a plurality of annular rims or flanges arranged on said wheel and each provided with a polishing surface and arranged transversely out of line with the companion rim.

2. A polishing machine comprising a rotatable wheel,'and a plurality of annular rims or. flanges of different diameters arranged eoncentrically on the same side of the wheel and each provided with a polishing surface and the inner rim projecting forwardly beyond the adjacent outer rim.

' 3, A polishing machine comprising a rotatable wheel having two peripheral sections of different diameters arranged side by side in a directlon lengthwiseof theaxis of the being provided .on its outer side ,with a polishing surface.
