Description
ALFRED M. RICKERD, OF RILEY. PENNSYLVANIA.
MINE-DRILL.
No. s35,s32.
Specification of-Letters Patent.
Patented Nov. 13,1906.
Application filed June 30, '1906. Serial No. 324,243.
To a/ZZ' whom it may concern,.-
Be it known that I, ALFREDM. Brennan, a citizen of the United States of America, residing at Riley, in the county of Allegheny and State of Pennsylvania, have invented certainv Vnew and useful Improvements in Mine-Drills, of which the following is a specific ation, reference being had therein to the accompanying drawings.
This invention relates to miners drills; and its primary object is to provide improved means for supporting a drill in such a manner pis to permit it to move within a limited raius.
A further object of the invention is to provide novel means for feeding a drill forward and for withdrawing itwhen desired.
The construction of the improvement will be fully described hereinafter in connection with the accompanying drawings, which form a part of this specification, and its novel features will be particularly set forth in the appended claims.
In the drawings, Figure 1 is a view in perspective of a drill embodying the invention. Fig. 2 is a detail vertical section, on an enlarged scale, of the bit-support. Fig. 3 is a side elevation of a treadle for moving the supporting-frame of the drill. Fig. 4 is a pers ective view of the bearing-block for the dfill-handle. Fig. 5 is a detail perspective view of a portion of the su porting-frame of the drill; and Fig. 6 is a si e elevation, on an enlarged scale, of the point of the drill-bit.
The reference numeral 1 designates a base provided with three parallel grooves 2, 3 and 4, serving as a trackway fora drill-supporting frame comprising parallel standards 5, connected at their lower ends by a transverse bar 6 and at points approximately midway of their height by a transverse rod 7 Above the rod 7 each of the standards is formed with an elongated vertically-disposed slot 8, said slots serving as guideways for oppositely-disposed threaded arms 9,projecting vfrom a block 1() arranged between the standards and vertically adjustable therein by means of clamping-nuts 11 fitting the ends of the screw-threaded arms 9 and adapted to fric'tionally engage the outer sides of the standards. To the lower endof each of the standards 5 is secured a roller 12, mounted in a bracket 13, said rollers being adapted to travel Within the grooves 2 and 4 of the base.
The block 10 is formed with a central horizontal bore 14, within which is fitted a bushing 15, flared at its outer end. Within the bushing 15 is supported a crank-shaft 16, provided at one end witha handle 17 and having its projecting forward end 18 screwthreaded for the attachment thereto o f the rear end of an internally-threaded couplingsleeve 19, within the forward end of whichis fitted the threaded end20 of a drill-bit 21. Secured tothe rear sides of each ofthe standards 5 is an inclined brace 22, the lower ends of which are recessed to provide tongues 23, fitting the grooves 2 and 4 of the base and adapted to move therein.
The numeral 24 designates a treadle, the forward end of which is pivotally secured upon the rod 7 by bending said end around the rod to form a loop 25. of the rear end of the treadle is secured a roller-bracket 26, within which is mounted a roller 27, adapted to move within the central groove 3 of the base. The front 28 `of the drill is bifurcated, as shown in Fig. 6, to provide two spirally-turned cutters 29.
The utility and operation of the mechanism constructed as thus described will be readily understood. The flared bushing which serves as the bearin for the crank-shaft permits the shaft and t e bit coupled thereto to be moved to any point within the radius of the enlarged end of the bearing, and the vertical adjustment of the bit and its operatingcrank ma be readily effected by means of the threa ed arms 9 and the nuts 11. The forward feed of the frame carrying the bit is accomplished by pressure of the foot upon the treadle 24, the rollers on the standards and treadle and the ton ues on the lower ends of the braces 22 enaling the frame to be readily moved by the foot of the operator. The bit-coupling facilitates the replacing of bits when required,
What I claim, and desire to secure by Letters Patent, is-
1. A miners drill comprising a grooved base, a vertically-disposed frame comprising standards movabl supported thereon, means for moving said rame, a vertically-adjustable bearing-block supported between the standards of the frame, a flared bushin within said block, and a crank-shaft mounte within said bushin 2. In a miners drill the combination with a grooved base, of a movable frame comprising standards havin rollers within the grooves and formed with vertically-disposed slots, means for moving said frame upon said To the under sideA ICO IlO
base, a block having oppositely-pro'ecting threaded arms extending through sai slots, nuts on said arms for securing said block at dilierent vertical adjustments, a flared bushing extending through said block, a crankshaft Within said bushing, a coupling-sleeve on said shaft, and a bit detachably secured to said sleeve.
3. In a miners drill the combination With a grooved base7 of a drill-supporting frame thereon, comprising parallel standards carrying rollers, and inclined braces secured to said standards and provided with tongues to lit the grooves of the base, and a treadle secured at one end to the frame, and provided with a/roller'at its opposite end.
4'. In a miners drill the combination with a grooved base of a frame comprising parallel ALFRED M. RICKERD. Witnesses'.
