Abstract
552,305. Percussive tools. CLIMAX ROCK DRILL & ENGINEERING WORKS, Ltd., and ST. STEPHENS, R. DE H. Dec. 3, 1941, No. 15591. [Class 124] The steel a of a rock drill or like percussive tool is provided with a coating of brass to which a collar b consisting wholly or mainly of natural or synthetic rubber is bonded by vulcanization under pressure at a raised temperature. The brass coating may be applied by electro-deposition, or by means of a spray pistol. The collar may be reinforced by sheet metal and caps c, d, Fig. 2, spaced metal washers g, Fig. 4, or metal particles mixed with the rubber.
