Abstract

324,265. Pryce, L. Feb. 19, 1929. Percussive tools.-The striking end of the hammer piston or anvil block is formed with a spherical recess 13, preferably ground after hardening, and the end of the tool 12 is formed with a similar or approximately similar surface, in order to reduce damage due to the tool getting out of alignment through wear of the chuck bushing.
