Abstract

751,242. Screwing-up nuts. CHICAGO PNEUMATIC TOOL CO. March 1, 1954 [March 31, 1953], No. 5921/54. Class 83 (3). [Also in Group XXIII] A percussive tool comprises means for delivering hammer blows and a rotary impact attachment 28 connectable at will to the front head of the tool to produce intermittent rotary movement in the attachment for screwing-up nuts. The attachment comprises a housing 50 screwed to a cap 51 and supporting a ratchet ring 52 with a square-sided extension 53. A rifle-nut 54 within the ratchet engages helical splines on a rod 63 which enters the chuck of the percussive tool and is urged rearwardly by a spring 64. The extension 53 carries a head 67, having a resilient cushion 69 and a nutengaging socket 68a. Blows by the percussive tool on the rod 63 are converted to intermittent rotation of the nut 54, and, through ratchetring 52, to rotation of the socket 68a. The body of the tool is supported on a cylinder 24 having a piston-rod 25 operated by compressed air.
