Abstract

181,194. Williams, V. L. April 21, 1921. Percussive drills. - The hammer of a percussive rockdrill is incorporated weith the twist-mechanism and is operated by the teeth of a star-wheel 2 driven by hand or power. The cam lever 6 is pivoted in an adjustable block 31 and actuates the hammer 8 which is connected to an axially-sliding spring case 15 by means of a thrust stud 17 and a ratchet wheel 16. The hammer twists the drill socket 23 at each inward stroke by means of balls 28 mounted in the socket and engaging inclined flutes in the hammerhead. The blow is regulated by means of an adjustable spring cam 12, and the stroke is controlled by adjustment of the block 31. A spring 35 absorbs normal thrusts on the cam-lever pivot, but excessive strains are taken by the adjustable abutment 37. Ball bearings are used for the principal working parts, and an inspection cover is provided for the star-wheel mechanism.
