JOHN c. HUNTER,- or SAN nnnnorsoo, CALIFORNIA.
TOOL-HOLDER.
SPECIFICATION forming part of Letters Patent No. 502,564, dated August 1, 1893.
Application filed October 31, 1892. Serial No. 450.574. (N0 model.)
To all whom it may concern:
Be it known that 1, JOHN CHRISTOPHER HUNTER, of San Francisco, in the county of San Francisco and State of California, have invented a new and Improved Tool-Holder, of which the following is a full, clear, and exact description.
The invention relates to tool holders for lathe, planing, shaping, slotting and other machines.
The object of the invention is to provide a new and improved tool holder, which is simple and durable in construction, very effective in operation,,and arranged to readily fastenthe desired tool in the proper position.
The invention consists of a head made in sections between which the tool is clamped, one of the sections being adapted to be seated in the stock.
The invention also consists of certain parts and details, and combinations of the same, as will be hereinafter described and then pointed out in the claim.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts inall the figures.
Figure 1 is a front elevation of the improvement with parts in section. Fig. 2 is a side elevation of the same with parts in section. Fig. 3 is aplan view of one of the head sections. Fig. 4: is a side elevation of the same. Fig. 5
. is a plan view of the other head section. Fig.
6 is a side elevation of the same. Figs. 7 and 8 are perspective views of different tools. Fig. 9 is a sectional plan view of a modified form of head. Fig. 10 is a sectional side elevation of the section of the head shown in Fig. 9. Fig. 11 is a plan view of another modified form of head with the tool in section. Fig. 12 is a side elevation of one of thehead sections shown in Fig. 11. Fig. 13 is a perspective view of another tool, and Figs. 14 and 15 are cross sections of different tools.
The improved tool holder is provided with a stock or body A, adapted to be secured to the machine on which the holder is to be applied. In the stock A is formed a socket B, in which is adapted to be seated the conical shank O of the head section 0, forming part of the head D, provided with another head section E, between which and the head section 0, the tool F is clamped.
As shown in the drawings the head section E is formed with a rod E, extending through the head section 0, and its shank O and also through a corresponding aperture formed longitudinally in the stock A, the end of the said rod being screw-threaded and engaged by a nut E adapted to screw up against the end of the stock, to draw the head section E- firmly onto the tool F held between the two head sections E and O.
In order to prevent the head section E from turning, I make part of the rod E fiat as at E to form a tongue to engage corresponding recesses 0 formed in the other head section 0. In order to securely'hold the tool F in the proper position, I provide the two sections with recesses or grooves corresponding to the cross section of the tool so that when the nuts E are screwed up, the tool is securely clamped in place between the head sections.
As shown in the drawings, the adj acent'faces of the head sections are preferably inclined so as to hold the tool in an angular position relative to thestock A; In the face or end of the head section 0 is formed a transverse groove, shaped according to the half cross section of the tool F, which latter also passes through a correspondingly-shaped aperture in the flat part of the rod E, as plainly shown in Fig. 5.
I do not limit myself to any particular form of grooves for the tool as the said grooves and apertures are varied according to the cross section of the tool employed, and also do notlimit myselfto the particular construction of the heads, as the same may be varied according to the use of the tool on a particular machine.
Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- A tool holder comprising the longitudinally bored stock A having a socket B in its outer end, the head section 0 having a longitudinal bore, a shank O fitting the socket- B, and provided with transverse intersecting recesses or grooves across its front face, the rod E extending through the head section 0 and the stock and formed at its outer end with the outer head section E having a flat portion E entering one transverse recess 0 in the sec tion 0 and having a transverse opening and an intersecting groove receiving the tool or cutter, and a nut on the opposite end of the rod to draw the head section E inwardly and bind the tool in the opposed transverse reoesses in the two head sections,substantially as set forth.
