(2.) A rock-drill in which a hammer reciprocates in a cylinder and acts by percussion on the end of the drill-bit, such hammer acting in conjunction with suitable ports in the cylinder so as to also constitute the valve for the distribution of the fluid-pressure whereby same is actuated. (3.) In a rock-drill constructed as set forth in the preceding claim, the formation of a circumferential row of holes in the forward end of the drill-cylinder for permitting the exhaust fluid from such cylinder to pass outwards and prevent the rock-cuttings flying back on to the machine and over the operator. (4.) The improved drill-bit with an enlarged circular rock-cutting head, the acting face of which is provided with a circular row of V-shaped lips radiating from the centre outwards, while a bore is formed through the body of the bit and is open to the drill-cylinder at its rear end in order to permit fluid to pass through said bit and impinge against the work for the purpose of driving or carrying off the rock-cuttings. (5.) In a rock-drill bit constructed as set forth in the preceding claim, the formation of a groove between each two of the circular row of V-shaped lips, such groove extending backwards from the head and merging into the shank of the bit. (6.) A column and clamp for fixing rock-drilling engines in position when necessary, composed essentially of a clamping-device to receive the drilling-engine, and a bar connected therewith and having an abutment foot-piece at one end, and a screw-threaded rod at the other end terminating in a ball to enter a socket in a second abutment foot-piece.
