Abstract:
This invention relates to jewelers' lathe-chucks, and has for its object to provide an adjustable or movable bottom, stop, step, or gage within the chuck-head, whereby the dis- 5ance to which objects inserted between the chuck-jaws may be conveniently and certainly regulated and determined. An adjustable stop of this character will obviously enable the Length of an object to be readily gaged, or the position of a shoulder or recess determined with reference to the end surface of the object when placed in contact with the adjustable stop. The adjustable stop also will afford a convenient means of gaging the length of arti- 2 Iles when several are to be made of the same dimensions, and said stop will be otherwise useful in many ways obvious to a skilled workman.
Claim:
The combination, with a hollow split chuck, C, and a hollow chuck-spindle, B', provided with a hand-wheel, of a stop, D, and a longitudinally-adjustable stem, E, attached to the stop, said stein being extended through the hollow spindle to a point exterior to the said spindle and the band-wheel thereon. |
