Abstract

1236. Newton, P. A., [Ingersoll-Rand Co.]. Jan. 17. Percussive drills.-In pneumatic hammers, for conveying the rotation of the cylinder 1 to the tool, the tool-holding bushing 4 is provided with lugs 5, 6 which interlock with grooves in the end of the cylinder, the bushing being retained in this position by a pin 12. A spring 13 retains the pin in position and is prevented from turning sufficiently to uncover the pin by a stop 15.
