Abstract

246,821. Chicago Pneumatic Tool Co., (Assignees of Penberthy, E.). Jan. 27, 1925, [Convention date]. Percussive drills. - In a percussive drill having a piston 10 reciprocated in a cylinder 5 by pressure fluid controlled by a throttle valve 12, the tool 19 is supported in a chuck 20 keyed to a sleeve 21 arranged in the front head 6 of the cylinder. The sleeve 21 has grooves engaged by longitudinal ribs 10<b> on an extension 10<a> of the piston, the extension being guided in a sleeve 18. A rifle bar 22 cooperating with a nut 24 in the piston has a head 26 carrying pawls cooperating with a ratchet ring 27 secured in a chamber in the cylinder head 7, whereby, during the downstroke, the bar 22 is caused to rotate, and, during the upstroke, the piston is caused to rotate, causing rotation of the tool 19.
