Hollow Mill
|
Otto Ebert |
Cleveland, Cuyahoga County, OH |
Claim:
his invention relates to hollow mills or milling cutters of the adjustable or expansible type, and in some respects it is an improvement on the mill shown in my U. S. Patent No. 1,165,859.
The object of the present improvement is to provide improved means for simultaneously clamping the cutters at adjustment, thereby saving the time and labor of separate fastenings.
When three cutters are used, the clamping ring will bind on all the cutters equally. The cutters are adjusted by means of a rear adjusting nut which can be set up to ix the parts as desired, Both the adjusting and the clamping nuts are operated by a spanner wrench. |
