Description: |
| Claim:
This invention relates to an improved mounting for lathe centers and the like. These lathe center mountings are incorporated in the conventional tailstock as currently employed in lathe construction. More specifically, the invention relates to a mounting which will permit the work centering element to move relative to the tailstock when undue axial pressure is put upon the center as occurs when the work expands in the course oi the cutting operation.
In the development of this art there have been a number of devices disclosed and claimed in patents which have had the purpose of permitting expansion of the work. One of the earlier examples of this type of device is found in the patent to Müller, No. 1,318,223, issued 07 October, 1919, wherein a spring was employed to permit yielding of the work center in accordance with the expansion of the work. However, as the art of turning has developed, that is, with the advent of high speed tools and the procedure of dry cutting, the amount of heat generated in the work has increased. It will be seen that the tailstock structure and the work center mounting must be of rugged construction to properly support the work under these conditions and yet at the same time, the device, permitting axial expansion of the work, must do so readily and in the proper amount. |
