Abstract

346,217. Percussive rock drills. POTTER, H. S., 23, Cullinan Buildings, Main Street, Johannesburg, South Africa. May 31, 1930, No. 16883. [Class 124.] Rock-drill shanks enlarged in the manner described in Specification 324,412, [Class 124, Stone &c.], are further provided with a forward collar or sleeve, such as a rubber ring 5, or an integral metal enlargement 9, or both, for the purpose of preventing the shank from working back into the barrel. A steel ring 7 may be shrunk on outside the rubber ring, or the metal collar 9 may carry an outer steel ring fixed by welding or otherwise.
