(4.) In a drill or similar instrument, the combination with a suitable support of a revoluble air-shaft mounted thereon, a cylinder fast on the air-shaft and rotating therewith, a piston-hammer located in the cylinder and operated by the air from the said shaft, a bit mounted on the cylinder and arranged to be driven by the piston-hammer, and means operated independently of the movement of the piston-hammer for rotating the air-shaft, the cylinder, and the bit. (5.) The combination of a revoluble cylinder, a piston-hammer located therein, a bit mounted on a cylinder and adapted to rotate therewith, said bit being arranged to be operated by said hammer, and means for delivering to the cylinder air or other suitable fluid for operating the hammer. (6.) The combination of a revoluble cylinder, a piston-hammer located therein, a bit mounted on the cylinder adapted to turn therewith, and arranged to be operated by the piston-hammer, and means for automatically rotating the cylinder and bit. (7.) In a drill adapted to be operated by air, the combination of a cylinder, a piston-hammer located therein, a drill-bit mounted on the cylinder and adapted to be operated by the hammer, an air-shaft fast on the cylinder and arranged to deliver air thereto for the operation of the hammer, means also operated by air for rotating the cylinder, and suitable means for cutting off the flow of air to the cylinder while the rotating mechanism is in operation. (8.) The combination of a drill-bit, a piston-hammer, an air-shaft for delivering air to the cylinder, a motor, a pinion fast on the motor-shaft, and a gear fast on the air-shaft and meshing with the pinion. (9.) The combination of a drill-bit, a cylinder upon which the bit is mounted, a piston-hammer located in the cylinder, an air-shaft connected with the cylinder and adapted to deliver air thereto, a feed-screw, a motor, a pinion fast on the shaft of the motor, a gear fast on the air-shaft and meshing with the pinion, means for delivering air to the motor, and means for cutting off the flow of air to the cylinder while the motor is in operation. (10.) The combination of a revoluble cylinder, a piston-hammer located therein, a bit mounted on the cylinder and arranged to rotate therewith, said bit being adapted to be operated by said hammer, means for delivering to the cylinder air or other fluid for operating the hammer, and means operated independently of the hammer’s action for rotating the cylinder and bit.
