TOOL-HOLDER.
SPECIFICATION forming part of Letters Patent No. 739,750, dated September 22, 1903.
Application filed May 11, 1903.
To all whom it may concern.-
Be it known that I, EDWARD A. WARBUR- TON, a citizen of the United States, and a resident of Philadelphia, inthe county of Philadelphia and State of Pennsylvania,have made a certain new and useful Invention in Tool- I-Iolders; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.
Figure 1 is a perspective View of my invention with tool in place therein. Fig. 2 is a longitudinal section of the same on the line 2 2, Fig. 3, with reversed position of tool indicated in dotted lines. Fig. 3 is a section on the line 3 3, Fig. 2.
The invention has relation to tool-holders chiefly designed for lathe and planing tools; and it consists in the novel construction and combination of parts, as hereinafter set forth.
In the accompanying drawings, illustrating the invention, the letter a designates the shank of the tool-holder,.and b the seat-lug, which projects laterally from the lower end of the shank. Extending through the lug is the tool-seat c for a tool d. On each side of the tool-seat is provided a threadedaperture 6, designed to receive and engage a set-screw .9. These apertures are opposite to each other and communicate with the tool-seat, their inner ends opening through the inclined walls 25 of said seat.
The tool-seat is an elongated passage which is rectangular in cross-section, two opposite walls 70 is being parallel to each other and the other two opposite walls it being somewhat inclined upward and outward away from each smart. 156.646. (NemodeL) other in such wise that while the lower opening m of the seat is of proper size and shape to neatly conform to the shank of the tool the seat gradually becomes larger upward between the walls it to provide for adjustment of the angular position'of the tool in the seat; but in order that the adjustment may be readily made and that there shall be no lateral play the lateral walls 70 it are parallel.
The tool can beplaced in the seat so as to face in either direction for working, and when adjusted the set-screw is turned home against the shank of the tool, giving it the proper rake. The holder is therefore both righthand ed and left-handed. The seat-lug projects laterally from the shank of the holder, so that the tool can be removed or adjusted without removing the holder from its place.
The holder is of economical construction, as it can be made of cast metal and of sulficient size to avoid springing.
EDWARD A.'WARBURTON.
