Abstract

198,028. Sangster, C. Feb. 20, 1922. Percussive hand tools. - The anvil block j is struck by the hammer g with a glancing blow under the action of a spring h, the hammer being rotated by a member d which is driven by a flexible shaft and to which the hammer is connected by tongues at an angle to the axis. Rotation of the block is prevented by feathers r. The force of the blow depends on the pressure put upon the work and on the. speed of rotation, the tool being mounted in a socket q. Lubricant introduced at s collects in a. recess t, which is provided with a drain hole (not shown).
