Abstract

328,685. Holman, A. T., and Holman, K. J. Feb. 4, 1929. Channels in percussive drills. - In a percussive drill or like tool comprising a hammer piston 10 working in a cylinder 17 and cooperating with rifle-bar mechanism 12, 13 and with a chuck sleeve 19, a conduit 30 leads from a port 31 in the cylinder, located behind the exhaust port 26, to a space 32 around the drill chuck 20, whereby oil scraped from the interior of the cylinder by the piston into the port 31 is blown through the conduit 30 to the outer surface of the chuck. The conduit 30 may also deliver to the outer surface of the chuck sleeve 19. The drill is fitted with an air-line oiler, and the blowing means described in Specification 328,977, [Class 124, Stone &c.], may also be provided.
