Abstract

8648. Flottmann, H. April 14, 1909, [Convention date]. [Addition to 6667/09.] Percussive drills.-In a water-supply device for hammer rock drills of the type described in the parent Specification, the water-supply chamber has solid ends forming drill guides; and the packings are forced apart and compressed by a forked wedge-piece acting between them and adjustably held by a nut, or by spring or water pressure. The water chamber f is mounted on the drill a between a collar b and the drill chuck e, and water passes from the hose h through the chamber to a passage i in the drill. The packings k, k<1> are capped by rings l, l<1> with bevelled inner sides against which acts a vertically guided forked wedge-piece o, which may be adjusted by a nut m acting directly or through a spring n, or by water pressure acting on a piston on the wedge-piece. The Specification as open to inspection under Section 91 (3) (a) states that the whole arrangement may be built into an extension of the rock drill casing. This subject - matter does not appear in the Specification as accepted.
