Description
UNITED STATES PATENT OFFICE.
STEPHEN MCOLELLAN, OF SAN MARCOS, TEXAS.
BRACE FOR BORING HOLES, 800.
SPECIFICATION forming part of Letters Patent No. 514,660, dated February 13, 1894.
Application filed March 16 l 893.
To all whom it may concern.-
Be it known that I, STEPHEN MCCLELLAN, a citizen of the United States, residing at San Marcos, in the county of Hays and State of Texas, have invented certain new and useful Improvements in Braces for Boring Holes Through the Sash and Jambs of WVindows; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.
My invention is a brace for boring holes through a window-sash and jamb; and consists in the novel construction and arrangement of its parts. It was invented by me more particularly to enable me the more quickly and better to apply my sash lock, patented J nly 19, 1892, and numbered 479,152, but may be used for other purposes.
In the accompanying drawings: Figure 1 is a top view of my invention, and Fig. 2 is a longitudinal sectional view of the same with the universal ball joint left off. Fig. 1 is a full sized drawing of my machine, and Fig. 2 shows the depth or thickness of the same from top to bottom, butthe machine may be made larger or smaller.
The bottom rests against the glass and is perfectly level, the edges are at right angles to the face of the bottom, so that when I set the machine on a level place with the bottom against the glass, it bores a perfectly true hole, either on the right or left side of the window.
My invention is described as follows:
In the accompanying drawings A, represents the rectangular frame, a, a, the braces that cross at the center.
a represents arms bearing in their extreme ends handle B; these arms a incline upward or outward, so that the handle B, may be grasped without the hand coming in contact with glass or other surface, against which the bottom of the machine rests, and to the Serial No. 466,370. (No model.)
have a universal ball joint connection H, as
shown in Fig. l. The braces a, a, are enlarged at their center and through such enlargement have a perforation 0', smaller at its upper than at its lower end and having a shoulder to bear the head (1, of the spindle d. Said spindle 61, works entirely above the shaft 0; the shaft 0, is journaled in hearings in the frame A, and has on its front outer end a boring brace-head 6, provided with a screw e, or may have a common brace chuck to hold the bit 6 and on said shaft and just inside of the frame, is secured a beveled gearwheel F; and on said shaft is also secured a keeper f, the rear face of which rests against the front face of the brace a. On the shaft d, and just above the upper face of the frame A, is rigidly secured a beveled gear-wheel G, same size or may be several times greater in diameter than the gear-wheel F, if more speed is required. On the shaft d, and to the upper face of the wheel G, is secured a crank handle g; the upper end of the shaft 01, is shaped like a bit-head, so that a boring brace may be put thereon, and, the wheel G, turned by means of such brace. It will be seen that the bit e may be rotated by means of the handle g, or by a brace on the shaft 0, or end of the universal ball joint connection H, or on the shaft cl.
Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. A brace for boring holes, consisting of the rectangular frame A; raised armsa secured to the rear end of said frame; handle 13, secured between the ends of said arms, said frame having at its center the perforation 0'; shaft 0, centrally and longitudinally journaled in said frame, and having on its front end a brace head; beveled gear-wheel F, secured on said shaft; headed shaft d, working in perforation c; beveled gear-wheel G, secured on said shaftand meshing with beveled wheel F, and crank-handle g, secured to shaft (1, substantially as shown and described and for the purposes set forth.
2. A brace for boring holes, consisting of the rectangular frame having its sides at right angles to its base 3 raised arms a secured to its rear end; handle B, secured between the said arms, said frame having at its center the perforation c; shaft 0, journaled centrally and longitudinally in said frame and bearing on its front end a brace-head, and beveled gear-Wheel F, and on its rear end a universal ball joint H; shaft 01, Working in perforation c, and having its upper end shaped to fit the head of a boring brace; and beveled gearwheel G, secured on said shaft d, and meshing with beveled wheel F, substantially as shown and described and for the purposes set forth.
3. A brace for boring holes, consisting of a rectangular frame having its sides at right angles to its base; raised arms a secured to its rear end; handle B, secured between the said arms, said frame having at its center the perforation a; shaft 0, journaled centrally and longitudinally in said frame and bea ring on its front end a brace-head, and beveled gear-Wheel F, and on its rear end a universal ball joint H; shaft d, working in perforation a; beveled gear-wheel G, secured on said shaft and meshing with beveled Wheel F, and crank-handle g, secured on said shaft d, substantially as shown and described and for the purposes set forth.
4; A brace for boring holes, consisting of the rectangular frame A; raised arms a and handle 13, the edge of said frame being at right angles to its bottom; shaft 0, journaled centrally and longitudinally in said frame and having on its front end a device for holding a bit and on its rear end a universal ball joint, substantially as shown and described and for the purposes set forth.
5. A brace for boring holes, consisting of the frame A, having the raised arms a and handle 13, the edges of said frame being at right angles to its bottom; braces a, a, having at their center the perforation a, shaft 0, journaled in said frame and bearing on its front and outer end a brace-head e, and inside of the frame beveled gearwheel F, and keeper f, working against the front of the brace a; headed shaft d, working in perforation 0, and having its upper end shaped to fit the head of a boring brace; beveled gearwheel G, secured on said shaft d, and meshing with beveled wheel F; crank-handle g, secured on shaft cl, and to the upper face of wheel G, substantially as shown and described and for the purposes set forth.
In testimony whereof I affix my signature in presence of two witnesses.
STEPHEN MCCLELLAN.
