CONE-CENTER FOR LATHES.
Application filed February 16, 1911.
Specification of Letters Patent.
Patented Jan. 30, 1912.
Serial No. 609,010.
To all whom it may concern:
Be it known that I, THOMAS H. MACK, a citizen of the United States of America, and resident of Balboa, Canal Zone, Panama, have invented certain new and useful Improvements in Cone-Centers for Lathes, of which the following is a specification.
My invention relates to a turning lathe of the class in which a cone center is applied to the center pin.
The objects of the invention are to provide that a single cone may operate on many difierent sized lathes; and to furnish a cone center that is simple in construction and operation.
Figure 1 is an end elevation. of the cone center. Fig. 2 is a longitudinal section of the same device. Fig. 3 is a side elevation of the center pin and its spindle. Fig. 4 is a section of a portion of the device with a ring of different size.
The device consists of a cone center A, having a central cylindrical bore B, open atthe right hand end, and having a conical bore C at the other end, and having an annular recess D, in the inner edge of the open end, a bushing ring E, fastened by set screws F, to said cone A, and located in said recess, and of smaller diameter than that of Copies of this patent may be obtained for said cylindrical bore C, a center pin spindle G fitting loosely within said core, and a center pin H held by said spindle and terminating in the conical bore C.
J represents a smaller ring by which the same cone A is adapted to fit upon a smaller spindle. Rings of several sizes may be provided. The outside diameters of such rings should be equal to one anothenbut the inside diameters should be successively smaller and smaller.
I claim as my invention,
In an article of the class described, the combination of a cone center, having a central cylindrical bore open at one end, and having a conical bore at the other end, and having an annular recess on the inner periphery of the open end, a bushing ring, located in said recess and of smaller diameter than that of the cylindrical bore, set screws fastening said ring to said cone center, a center pin spindle, fitting within said ring, and a center pin held by said spindle and adapted to fit the conical bore.
