BORING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 258,716, dated May 30, 1882.

Application filed March 16, 1882.

To all whom it may concern:

Be it known that I, VINCENT 00X, of New 2 is a vertical longitudinal section of the same.-

This invention consists in a machine or tool of simple construction, whereby every facility is afforded for boring holes in wagon or buggy fellies and other articles both in straightlincs and in various angular directions without shifting the article being bored, substantially as hereinafter described.

A in the drawings indicates the frame or stand of the machine on which the felly B or other article to be bored is placed, and upon which it is secured by a clamping-screw, O. Said frame A is here shown as formed of a table or base, 0, upon which the folly rests, and an open guard, I), projecting upward from the front of said base, and against which the inner side or one edge of the telly bears. Attached to and projecting centrally and horizontally outward from the frontof this frame is an arm,

. D, having an eye, 1, opening up through its outer end andfitted with a side set-screw, c, for holding in place, as adjusted up or down or around within said eye, a circular post, E. This post is also constructed with an eye, at, at its upper end, whereby it is made to form the bearingpost for the shaft or rotating holder G, which carries at its inner end the bit or auger G, and which shaft corresponds with the shank of the bit or anger. This shaft G is fitted to work loosely or freely through the eye (I of the post, and is provided on its outer end with a crank or handle, 0, for operating the bit or anger.

With the machine or tool thus constructed every facility is afforded for boring either a straight hole through the fclly without gaging (No model.)

or marking that is, a hole parallel with the arm D or a hole at any desired angle theretoand inclining up or down or to the right or left, the adjustability of the post E, longitudinally and axially, and free fit of the shaft Gr through its eye, providing for such varied action of the boring-fool. For ordinary variations in the angular direction ofthe holes to be bored, and for straight holes, it will notbe ncc cssary even to disturb the bearing of the shaft G or move the post E, as the hole in the eye at of the post is constructed with arolling bearing-surface for the shaft G-thatis, a bearingsurface in which the shaft G is free to roll in vaiious directions, as shown in Fig. 2.

Upon the base a of the frame A is a centering projectiomf, in line with the arm D, whereby the adjustment of the telly on the frame and proper direction of the-bit at starting is facilitated.

The machine, which is simple, cheap, easily adjusted, and not liable to get out of repair, may be used not only for felly-boring or boring holes in curved pieces of timber, but also for boring holes in straight pieces of scantling or timber f r making gates or other carpenter work.

Having thus described my invention, Iclaim as new and desire to secure by Letters Patent- 1. The combination, with the frame A and the clamping-screw O, of the bit orauger holding and operating shaft G, and the supportingpost E, having a rolling bearing-surface, substantially as herein shown and dcscribed,whereby the direction of the bit or anger can be varied, as set forth.

2. The combination, with the frame A, provided with a clamping-screw, O, and forwardly-projecting arm D, of the post E, adjustable both longitudinally and axially within and through said arm, and thebit or anger holding and operating shaft G, supported in an eye,d, ofsaid post, constructed to form a bearing having a rolling surface, essentially as shown and described.

- VINCENT 00X.
