AMAZIAH OOVEY AND SAMUEL JAMES OOVEY, OF SIGOURNEY, IOWA.

COAL-DRILLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 375,262, dated December 20, 1887.

Application filed July 8, 1887.

To aZZ whom it may concern:

Be it known that we, AMAZIAH Cover and SAMUEL JAMES COVEY, citizens of the United States, residing at Sigourney, in the county of Keokuk and State of Iowa, have invented a new and useful Improvement in Drilling- Machines, of which the following is a specification.

Our invention relates to an improvementin coal-drilling machines; and it consists in the peculiar construction and combination of devices, that will be more fully set forth hereinafter, and particularly pointed out in the claims.

In the drawings, Figure l is a perspective view of a drilling-machine embodying ourimprovements. Fig. 2 is atop plan view. Fig. 3 is a vertical longitudinal sectional view taken on the line 00 mof Fig. 2. Fig. 4. is avertical transverse sectional view taken on the line 3 1 of Fig. 2.

A represents a bar, which is rectangular .in cross-section and is adapted to be driven in the bed of coal or other material to be drilled or mined. Spikes are provided to engage more firmly with the coal-bed.

B is a collar or sleeve, which fits on the said bar and is adapted to slide longitudinally thereon, and the said collar or sleeve is provided with a set-screw, G, by means of which it maybe clamped at any desired longitudinal adjustment on the bar. From the upper side of the sleeve or collar B-projects a vertical headed stud, D, on which is journaled a frame, E. The said frame comprises two sections, F, made of cast metal and bolted together on opposite sides of the stud D, and provided with outwardly-extending arms G, the ends of which are upturned and provided with transverse aligned openings H.

I represents a frame,which is provided with projecting trunnions K, journaled in the openingsH. From the upper side of the frame, on the sides thereof projecting from the trunnions,extend two pairs of vertical ears, L, that are provided with aligned openings M. The pides of the frame intermediate between the sairs of cars are provided with screw-threaded collars N, which align with each other and are arranged at right angles to the axes of the trunnions.

Serial No. 243,786. (No model.)

0 represents a screw,which extends through and works in the collarsNin the frame I. The said screw is provided with a longitudinal groove, P, and on the ends of the screw are secured heads orsockets R, which are removable from the screw and are adapted to receive the'inner ends of boring bits or drills.

T represents a cylindrical sleeve, which is slipped over that portion of the screw between the openings M. From one side of the sleeve 'I projects a spindle, U, which is arranged at right angles with relation to the sleeve and has its outer end reduced and provided with screw threads.

V represents a sleeve, which slips over the spindle U and is adapted to rotate freely thereon, and to the inner end of the said sleeve is attached a miter gear-wheeLVV. Said wheel may be formed integrally with the said sleeve.'

The outer end of the sleeve is squared and adapted to fit a detachable crank-handle, X. Y represents a miter gear-wheel, which is arranged on the screw between the opposing ends of the sleeve T and one of the openings N. This gear-wheel is feathered or splined on the screw and is engaged by the wheel WV, a shown.

Z represents a hollow box,which is fitted on the sleeve V and in which the latter rotates, and the opposite sides of the said box are fiattened and thereby adapt the box to fit between either pair of cars L. A pin, A, is adapted to pass through the transverse openings of the upper ends of the ears and over the block Z to secure the latter in position.

The crank X is provided with an opening, B, of a suitable size and shape to adapt it, to be fitted onto one of the heads or sockets R, and thereby permit the screw-to be turned directly by means of the said crank when in confined spaces in which there is not sufficient room to attach the crank to the ends of the sleeve V. By this arrangement, also, the drill can be attached to either head R anddrill from either end.

By providing the frame I with the pairs of ears L on opposite sides thereof, and by pivoting the sleeve T on the screw, the spindle, the sleeve V, and the box Z may be swung to one side of the frame, and thereby enable the crank to be attached to either side of the same,

the crank-handle is attached to the outer end of the sleeve V, a nut, 13 is screwed onto the threaded end of the spindle U and caused to bear against the outer side of the crank, and thereby clamp the latter in position on the sleeve.

Having thus described our invention, we claim-- 1. The combination, in a drilling-machine, of the frame I, having the aligned threaded openings N on opposite side, the screw-shaft O, passing through and engaging said openings, the miter wheel G, feathered to said screw-shaft, the sleeve T, journaled loosely on the said screw-shaft and having the spindle U, the sleeve V, jonrnaled on said spindle, and the miter-pinion \V, attached to said sleeve and meshing with wheel Gr, substantially as described. I

2. The combination, in a drilling-machine, of the frame I, having the aligned threaded openings N, and the pairs of ears L on opposite sides and arranged at right angles to the openings N, the screw shaft 0, extending through and engaging said openings, the wheel Y, feathered to said screw-shaft, the sleeve T, jonrnaled loosely on said screw-sl1aft and having the spindle U projecting at right angles, the sleeve V, journaled on said spindle, the miter-pinion XV, attached to said sleeve and meshing with wheel Y, and the box Z, in which the sleeve V rotates and adapted to be fitted between either pair of cars, for the purpose set forth, substantially as described.

3. The combination, in a drillingmachine, of the sleeve or collar B, longitudinally movable on the draft-bar, the said collar having the headed stud D, the frame E, journaled on the said stud and comprising the two sections F, bolted together andprovided with the out wardly-extending arms G, the frame I, having the trunnions journaled in openings in the ends of the said arms, the serew-shaft, and the operatingshaft secured to the said frame and geared together, substantially as described.

4. The combination, in a drilling-machine, of the sleeve or collar B, the frame E, swiveled thereto, the frame I, journaled to frame E and having the ears L on opposite sides and threaded collars N at right angles to the said ears, the screw-shaft O, engaging the said openings and extending through the frame I, the sleeve T, loosely mounted on the said screwshaft and having the spindle U projecting from one side thereof, the miter-wheel Y, feathered or splined to the screw-shaft and arranged between one cnd of the sleeve T and the opposing end of one of the openings N, the sleeve V, journaled on the spindle U and having the pinion adapted to engage the wheel Y, the outer end of the sleeve being adapted for the attachment of the crank, and the box Z, ar ranged on the sleeve V and in which the lat ter is journaled, said box being adapted to enter the spaces between either pair of the ears L, substantially as described.
