WILLIAM BIXBY, OF BUFFALO, NEW YORK.
LATHE TOOL-HOLDER.
SPECIFICATION forming part of Letters Patent N 0. 772,271, dated October 11, 1904.
Application filed April 29, 1904.
T aZZ whom, it may concern:
Be it known that I, WILLIAM BIXBY, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Lathe Tool-Holders, of which the following is a specification.
This invention relates to lathe tool-holders, the object of the invention being to provide a tool-holder which is especially adapted for use in connection with inside turning tools, the construction of the tool-holder being such that bits or tools of different sizes may be securely held by the holder, the latter being especially designed foruse in connection with tools formed out of round steel.
Vith the above and other objects in view, the nature of which will more fully appear as the description proceeds, the inventionconsists in the novel construction, combination, and arrangement ofparts, as hereinafter fully described, illustrated, and claimed.
In the accompanying drawings, Figure 1 is a plan view of a tool-holder embodying the present invention. Fig. 2 is a side elevation of the same. Fig. 3 is a vertical cross-section taken through the head of the tool-holder in line with one of the clamping-screws.
Like reference-numerals designate corresponding parts in all figures of the drawings. Referring to the drawings, 1 designates the shank of the tool-holder, which may be of any suitable length, width, and thickness, according to the lathe in connection with which the tool holder is used. At its outer end the shank is connected with a cylindrical head 3, provided with a bore extending therethrough from end to end, the upper portion of the bore being semicircular or cylindrical, as shown at 4, while the lower portion of the bore is V-shaped, as shown at 5, or composed of downwardly-converging or angularly-disposed side walls. The head is further provided with upwardly-extending bosses 6, internally threaded to receive clamp-screws 7,
Serial No. 205,663. (No model.)
by means of which the tool proper or bit (shown at 8) is firmly fastened in place. Extending through the bore of the head is a shoe 9, which has converging lower faces corresponding to the angle of the walls 5 and a grooved or concaved upper side 10, forming a seat or gutter in which the tool or bit 8 is received and centeredjust beneath the impinging inner extremities of the clampscrews 7.
By employing several shoes 9 of different sizes the tool-holderis adapted to accommodate tools of widely-varying diameters, and a tool of very large diameter may be used by omitting the shoe 9 altogether, the converging lower walls of the head serving to properly center the tool. When the shoe is in place, the concaved upper side or gutter formed therein serves to center the tool immediately beneath the clamp-screws, so as to be held thereby.
The tool-holder of this invention is especially designed to accommodate round and half-round steel boring-tools of diflerent sizes or diameters.
Having thus described the invention, what is claimed as new 'is A tool-holder comprising a shank, a cylindrical head, connected at one end of the shank and provided with a longitudinal bore having a cylindrical upper wall and a V-shaped lower wall, a shoe of less width than the diameter of the bore and having a V-shaped lower surface to fit within the V-shaped portion of the bore, said shoe being recessed on its upper surface to receive and support a tool, said recess being arranged centrally of the shoe, and set-screws passing through the cylindrical head in alinement with said recess.
In testimony whereof I afiix my signature in presence of two Witnesses.
WILLIAM BIXBY.
