No. 13640.—23rd May, 1901.—PATRICK H. REARDON, of 13, First Street, San Francisco, California, United States of America, Mechanic. Improvements in engines for rock-drills.

Claims.—(1.) In a direct-acting engine, a fluid-actuated piston, and a distributing-valve to control the motion of said piston, and means applicable at will whereby the pressure of the actuating fluid is removed from one end of the valve to permit said valve to move in one direction by fluid-pressure. (2.) In a direct-acting engine, a fluid-actuated piston, and a tappet engaging therewith to effect the motion of a distributing piston-valve therein, and means applicable at will whereby the pressure of the actuating fluid is removed from one end of the valve to permit said valve to move in one direction by fluid-pressure. (3.) In a direct-acting engine, a fluid-actuated piston, and a tappet engaging therewith to effect the motion in one direction of a distributing-valve, a balanced distributing-valve, and means whereby the pressure of the actuating fluid is removed from one end of the valve at will while the fluid-pressure remains on the opposite end. (4.) In a direct-acting engine, a fluid-actuated piston, and a tappet engaging therewith to effect the motion in one direction of a distributing-valve, a balanced distributing piston-valve, and means whereby the pressure of the actuating fluid is removed from one end of the valve at will while the fluid-pressure remains on the opposite end. (5.) In a direct-acting engine having a fluid-actuated piston, a tappet engaged by said piston, a valve between which and the piston the tappet is interposed to effect the motion of the former by the reciprocation of the latter, one end of said valve being socketed into a recess, said recess having a passage or passages communicating with the valve-chest and with the exterior of the chest, and a valve controlling said passage or passages whereby communication is made with the recess for the actuating-fluid pressure or atmosphere at will. (6.) In a direct-acting engine having a fluid-actuated piston, a pivoted tappet, and a piston-valve between which and the piston the tappet is interposed to effect the operation of the former by the engagement of the latter, one end of said valve fitting snugly in a recess which is provided with a passage or passages communicating with the valve-chest and with the exterior of the chest, and a valve controlling said passage or passages whereby communication is made with the recess for the actuating-fluid pressure or atmosphere at will.

No. 13641.—23rd May, 1901.—PATRICK H. REARDON, of 13, First Street, San Francisco, California, United States of America, Mechanic. Improvements in attachments for rock-drills.

Claims.—(1.) In a rock-drill attachment, a shell provided with a pocket of two diameters, in combination with a column-clamp having a lug adapted to enter said pocket after the clamp is secured upon the column, and a device opposable to the lug whereby it is secured in said pocket. (2.) In a rock-drill attachment, a clamp provided with means adapted to secure it upon a column, opposable projections thereon adjustable with reference to each other and to the clamp, in combination with a drill-shell having a pocket of two diameters adapted to receive said projections after the clamp has been secured upon its column. (3.) In a rock-drill attachment, a feed-frame provided with a circular pocket of two diameters in combination with a column-clamp having a lug adapted to enter and engage with said pocket, and means independent of those for securing the clamp to the column for locking said lug securely therein. (4.) In a rock-drill attachment, a shell provided with a circular pocket of two diameters in combination with a clamp having a beveled lug adapted to enter and engage with said pocket, and a bolt having a hooking head adapted to enter and engage with the pocket whereby said clamp is securely attached to the shell. (5.) A rock-drill column-clamp having a projecting lug A¹, a device sliding in said clamp, and a lug B¹ substantially similar to A¹, a suitable device adapted to engage with A¹ and B¹ whereby the drill may hang loosely thereon, and means for operating the lugs whereby the drill is securely attached. (6.) In a rock-drill attachment, a feed-frame provided with a circular pocket of two diameters, in combination with a column-clamp having a device adapted to enter said pocket, and means independent of those for securing the clamp to the column for locking said device securely in said pocket.

No. 13642.—23rd May, 1901.—HUGH MAIDEN, of 10, Union Street, Pyrmont, New South Wales, Diver, and JAMES COURTS, of McKae Street, Petersham, New South Wales, Diver. Improvements in shear-legs.

Claims.—(1.) An improved sheer-legs, consisting of a rigid triangular frame, between whose splayed wings the lower ends of a pair of canting-legs are hinged, the said legs being supported and operated by means of a series of blocks and tackle connecting the top of the said legs to the top of the said frame, substantially as described, and as illustrated in the drawing. (2.) In an improved sheer-legs, a rigid triangular frame between whose splayed wings the canting-legs are hinged, and to the top of which the said legs are supported, substantially as described, and as illustrated in the drawing. (3.) The combination in an improved sheer-legs of a pair of hinged canting-legs whose arc of movement is equal to an entire quadrant, a rigid triangular supporting frame having splayed wings, a series of purchase-blocks and tackle connecting the top of canting-legs with the top of the supporting frame, and whose fall passes over a guiding sheave on the top of the supporting frame and thence to the drum of a winch, and a lifting-purchase consisting of a pair of blocks and tackle suspended from the top or near the top of the canting-legs, and whose fall passes over guiding sheaves on the top of the said legs and supporting frame and thence to a winch, substantially as described, and as illustrated in the drawing.
