UNITED STATES PATENT OFFICE.
FRANK E. GUDELL, OF CLEVELAND, OHIO.
GRINDING AND POLISHING WHEEL.
SPECIFICATION forming part of Letters Patent No. 527,196, dated October 9, 1894.
Application filed February 14, 1894:. Serial No. 500,111. (No model.)
To all whom it may concern.-
Be it known that I, FRANK E. GUDELL, a citizen of the United States, residing at Cleveland, county of Guyahoga, and State of Ohio, have invented certain new and useful Improvementsin Grinding and Polishing Wheels, of which the following is a specification.
This invention relates to wheels for grinding and buffing or. polishing, and consists of a loose belt attached at one or more points on the periphery of the wheel, which, when the Wheel revolves will spread and keep clear from the periphery of the wheel by the centrifugal force, the object of which is to provide a cushioned grinding and polishing sur face on the wheel, the purpose of which isto give to the belt a yielding faculty, so that when an article is held against saidbelt for grinding or polishing, the belt will not cut into or injure the article. The belts may have a scratch-brush, emery or buffing surface, and are made detachable for removal and replacement.
The invention is illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of a wheel having a belt attached in the manner above stated, showing one means of securing the belt. Fig. 2 is a side elevation of a wheel having a belt attached in a plain or simple manner, and showstho wheel at rest and the belt seen loose in its normal position. Fig. 3 is a similar side elevation, showing the wheel as revolving and the circle of the belt extended at an equal distance around the wheel, except at the point of attachment, by the centrifugal force of the revolving Wheel.
A represents a disk or wheel made of wood or other suitable material, having an eye at its center for attaching it to a mandrel.
B represents a band or belt loosely surrounding said wheel, the ends abutting and secured by screws or other detachable means. In Fig. 1 a raised place or block 0 is provided for attaching the ends of the belt onto, which, when the wheel revolves will fill out the full circle of the belt as the belt extends from the wheel by the revolutions of the same.
In Fig. 3, where the belt is attached to the periphery of the wheel, when the wheel is revolved, there would be a short depression in the belt at that point.
The block 0 in Fig.1, may be made of rubher to form a flexible or cushioned projection that would yield to the pressure of the article being polished, in like manner to the belt, and thus maintain a uniform cushion effect throughout the whole circumference of the wheel.
The belts may be of any desirable widths and coated with any of the grinding and polishing materials.
Having described my invention, I claim- In grinding and polishing wheels, the combination' with wheel A, of a loose belt B attached at one or more points to the periphery of the wheel, whereby the centrifugal force of the revolving wheel extends the circle of the belt, substantially as and for the purpose specified.
