in the bearings 40. On the shaft 39 are two pulleys 41 and 42. Passing around the shaft 41 is an endless belt 43, which in turn engages a pulley 44 on the shaft 6 of the wheel or ball 4. Another belt 45 engages the pulley 42 and a pulley 46, arranged on the shaft 7 of the wheel 5. The last-named belt is crossed upon itself in order that the rotation of the wheels or balls will be inward and in a direction one toward the other.

Attached to the under surface of the table and beneath the Wheels 4 and 5 are trou hs- 47 48, through which the wheels revo ve. Within these troughs are placed a mixture of ashes and water or other similar substance which may be used for smoothing or rubbing shaft 6.

the pins. In, order that the wheel 5 may be free to rotate, a recess 49 is formed in the shelf 20.

In Fig. 3 is shown a modified form of conveyer or carrier for the pins. In this form an endless belt 50 is employed instead of the hoop. By this arrangement a greater quantity or number of pins may be carried.

In the finishing or polishing machine the same construction is employed, with the exception that the troughs and spider are removed and rolls of different material are used or substituted.

The shelf a is supported above the frame I), and passing around the shelf is a hoop c. Passing around the hoop c is an endless belt D, which in turn engages thepulley d on the Secured to the under surface ofjthe belt are the hooks f. In this connection a modified form of hook is employed. Each hook comprises two sections, each terminating at one end in the upturned portion 9. The opposite end it of the section 3' is screw-threaded in order that it may be removably secured to the belt. The opposite end 7c of the section m is coiled about the section j. At the points a 0 each of the sections converge slightly in opposite directiors in ord er that the sections proper may be suitably spaced apart.

After passi: g from betweenthe abradingwheels it is found advantageous to provide meais for automatically removing the pins from the hooks. The preferred means for accomplishii g this result consists in securing to the table beneath thecarrier or conveyer a trip A, which is arranged on an incline and has upper end B free and in a position to contact with the pins and lift them from the hooks, said pins falling upon the table where they may be easily collected. This device may be used on both forms of machine.

'lhe conveyer in both forms of the machine at all times is to be so positioned with rela.

tion to the abrading-wheels that the hooks carried thereby will be on a line with the contacting plane of the wheels.

From the foregoing description it is thought that the operation and construction of the invention will be clearly apparent to those skilled in the art, it being noted that all changes may be resorted to that fairly fall within the scope of the claims without sacrificing the value thereof.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is a 1. In a device of the character described, a frame, abrading-wheels mounted thereon, a spring supported table arranged over the frame, a conveyer passing around the table and between the wheels, and hook-supporting means carried by the conveyer.

2. In a device of the character described, a frame, abrading-wheels carried thereby, and a conveyer adapted to pass between said wheels, said conveyer having hook-supporting means, and means for automatically throwing pins from the pin-supporting means.

3. In a device of the character described, a frame, abrading-wheels suitably mounted thereon, uprights on the frame, a table yieldably supported by-the upri hts, and a conveyer passing around the ta le and between the wheels.

4. In a device of the character described, a frame, abradin wheels mounted thereon, uprights on the ame, a table loosely mount ed on the uprights, springs interposed between the table and the bases of the u rights,

and a conveyer passing around the ta le and between the wheels.

5. In a device of the character described, a frame, abradin wheels mounted thereon, uprights on the rame, a table loosely mounted on the uprights, springs interposed between the table and the bases of the uprights for exerting an upward movement to the table, means carried by the uprights for limiting said upward movement of the table, and a conveyer passing around the table and be tween the wheels.

6. In a device of the character described, a frame, abradin wheels thereon, a table supported by the rame, a shaft, a spider on the shaft, a hoop on the spider arranged around the table and between the wheels, supporting means carried by the hoop, and means for rotating the shaft.

7.' In a device of the character described, a frame, abradingwheels mounted thereon, a conveyer passing between said wheels, articlesupporting means carried by the conveyer, and means carried by the frame, for automatically throwing the articles from their supporting means.

8. In a device of the character described, a frame, abrading-wheels thereon, a conveyer passing between the wheels, means on the conveyer for supporting articles, and a trip on the frame for throwing the said articles from their supporting means.
