IMPROVEMENT IN WATCHMAKERS WHEEL-STRETCHERS.
Specification forming part of Letters Patent No. 156,207, dated October 27, 1874 application filed February 2, 1874.
To all whom it `may concern.-
Beit known that I., RQYAL GowLEs, of
' Cleveland, in the county of Cuyahoga and State of Ohio, have invented a Watchmakers Wheel-Stretcher, of which the following is a specification v The object of my invention is to rapidly stretch the rims of --watchwheels by the cornbination of a tapering head, revolving roller E, and a revolving` anvil-wheel F, so arranged in an upright post, A, that the rim of the wheel will lie between them, and when the roller E is turned the wheel is carried between them, havingits axis rod arranged in the adjustable bearings D C, so that it may revolve, a-s seen in the elevation, Figure 1.Y The device is also 4 further illustrated in top view, Fig. 2, and in points of Wheels axle.
portion will be closed together, clamping and holding the said arm iirmly in place. `In the frame Gr are arranged two spindles, C D, which are held in place by set-screws, c d, which also enables them to be adjusted. The said spindles have sockets in their ends for receiving the In the top of the post A is also placed a set-screw, B, for regulating the bearing of the roller E on the rim of the Wheel to be stretched. The roller E is provided with a crank and handle H for turning the same.
By this arrangement a Watch-wheel having become worn or otherwise reduced may be readily and perfectly stretched to the desired dimensions. The pressure is so applied as to stretch the rim of the wheel just back of the teeth, so that they are not injured.
Having described my invention, I claim- The post A, roller E, frame Gr, adjustable bearings C D, and the wheel F, all constructed .and arranged to operate as shown, and for the purpose set forth. A
