Abstract
328,246. Sgonina, C. Dec. 4, 1928. Percussive tools. -A dust - collecting head for a rock-drill is made in one with an ejector, and comprises two tubular parts b, c with an inclined common surface b<1> and capable of axial adjustment by means of a nut d so as to' increase the overall diameter and jam the head in the hole. A rubber dust cap e is fitted at the front end and a dust-excluding sleeve f at the rear. The outlet a' is connected to a dust bag and is formed as an ejector, air being supplied to a pipe g from the main supply to the tool by means of an additional outlet n from the control cock i.
