POLISHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 732,657, dated J une 30, 1903.

Application filed July 8, 19(l2. Serial, No 114,807. (No model.) I

.To aZZ whom it may concern:

Be it known that I, HENRY SoHUEssLER, a citizen of the United States, residing at Peru, in the county of Lasalle and State of Illinois, have invented certain new and useful Improvements in Polishing-Machines, of which the following is a specification.

My invention relates to polishing-machines, especially to machines for polishing metal platessuch as tin, zinc, or the 1ike-and.has

- for its objects to produce a device of this nature which will be simple of construction,

'an enlarged sectional view of the clamping mechanism.

Referring to the drawings, 1 indicates the rotary buffing or polishing roller, which in practice is provided with a covering of felt or the like, mounted on a shaft'2, supported by bearings 3 and driven by pulley 4, connected by belt 5 with any suitable source of motive power.

6 is the bed or table, which receives and carries the metal plate or the like to be polished. This table preferably has its surface curved in the form of an arc of a circle and is supported on framework 7, mounted upon shaft 8, upon which it is oscillated to give the table and plate thereon a reciprocatory motion beneath the buffing-roller.-

9 is ahand-wheel fixed on shaftlO,which also has fixed thereto a toothed pinion 11, which meshes with rack 12, fixed on the framework of the table and through the medium of which motion is imparted to thetable.

13 is a counterweight fixed to shaft 8, which serves to equalize the gravity of the table, also carried by said shaft.

The plates are clamped to the table 6 at its upper end by means of a clamp comprising a clamping member proper, 14, in the form of a lip perforated at intervals to engage over lugs or projections 15, carried by the adjacent edge of the table. The clamping member 14 is carried by a rotary member 16, adapted to be operated by a hand-lever 17. In practice after the plate to be clamped has been inserted the clamping member 14 is pressed home and the lugs 15 enter the holes or perforation punch-holes along the edge of .driven buffing-roller 1.

What I claim is-- In a polishing-machine, the combination with a polishing-roller, of a reciprocating bed or table in the form of an arc of a circle and 'having a segmental-gear device secured to one side thereof, the normally highest terminal being cut away at a downward angle of inclination and provided with forwardly-inclined and provided with upwardly-extending transversely-alined projections, a shaft having a hand-wheel on the outer extremity and a gear on the inner extremity meshing with the segmental gear on the bed or table, the saidshaft through the hand-Wheel being reciprocated in opposite directions under the roller, and a clamping member movably mounted on the normally highest extremity of the bed or table and provided with a lip projecting over the downwardly-inclined portion of the upper extremity of the table or bed and having a series of sockets to receive the said projections.

In testimony whereof I affix my signature in presence of two witnesses.

HENRY SCHUESSLER;
