| A rotationally selectable lock apparatus includes an outer element having a plurality of locking pins that are radially spring loaded to extend and retract through the outer element. An inner element is substantially encircled by the outer element and coupleable to a driveshaft. The inner element is configured to cause the plurality of locking pins to retract through the outer element in response to the driveshaft rotating in a first direction and extend through the outer element to engage a housing in response to the driveshaft rotating in a second direction, opposite to the first direction. | ||||||

| A fluid-activated, percussive impact tool has a piston therein that reciprocates longitudinally but not rotationally. The piston activates a wrap spring clutch to rotate the drill steel. A removable splined nut in combination with the tool's housing restrains rotation of the piston, while permitting longitudinal reciprocation of the piston. | ||||||

| A clutch assembly transmits rotary motion in a percussive apparatus to a drill steel. The clutch assembly includes a first hub having a first cylindrical surface formed thereon. A second hub which is substantially rotationally coupled to the drill steel has a second cylindrical surface formed thereon. The second cylindrical surface is coaxial with the first cylindrical surface. A wrap spring engages a portion of both the first cylindrical surface and the second cylindrical surface, wherein relative rotary motion between the first hub and the second hub is permitted in a first direction and restricted in a second direction. The wrap spring clutch transmits motion supplied from a rifle bar assembly as well as a plunger bar arrangement. | ||||||

| Apparatus for drilling a bore hole comprising a hammer and a dual walled drill tube. The hammer comprises a reciprocable piston, fluid flow control device for directing fluid under pressure to the hammer to reciprocally drive the piston, and cutting device coupled to the hammer which rotate upon reciprocation of the hammer to cut the bore hole. Rachets are coupled to the cutting device to permit rotation of the cutting means in one direction only and to prevent rotation in an opposite direction. A portion of the fluid under pressure is diverted to entrain and direct particulate material to the surface of the bore hole. | ||||||

| A rock drill apparatus has features that allow it to be attached to a conventional impact tool. The rock drill attachment has a housing that is secured to the impact tool carriage below the hammer of the impact tool. A tappet is carried in the housing of the rock drill attachment for axial movement in response to blows from the hammer. The tappet is nonrotatable with respect to the housing and is adapted to deliver blows to a tool shank. A conversion device is coupled between the tappet and the tool shank to convert downward movement of the tappet into rotation of the tool shank prior to the impact of the tappet on the tool shank. A spring moves the tappet away from the tool shank after impact for repeating the cycle. The conversion device includes a sleeve with inclined splines that engage inclined splines on the tool shank. A clutch locks the sleeve to the tappet during downward movement to rotate the tool shank. During upward movement, the clutch allows the sleeve to rotate with respect to the tappet. | ||||||

| A rock drill has a housing accommodating pistons defining working chambers. Rotary drive of a drill steel has an overrunning clutch and a screw pair. The screw pair is arranged between the pistons and is formed by outer and inner helical threads respectively provided on these pistons. One of the pistons is kinematically connected with the housing, and the other piston which cooperates, during the drilling, with a chuck receiving the drill steel shank is in force transmitting connection with the rotary drive of the drill steel.The invention is aimed at lowering vibration of the rock drill housing by arranging the screw pair of the rotary drive between the pistons. | ||||||
