Abstract

479,414. Rock-drills. MOSS, E. W. (Ingersoll-Rand Co.) June 25, 1937, No. 17772. [Class 124] The rock-drill 26 is fed to the work by the rotary air motor 36 through the chain 30. Transmission of blows from the rook-drill to the motor is prevented by allowing the worm wheel 38 to slide freely on the motor spindle, its end thrust being supported on bearings.
