Abstract

103,287. Greve, L. W. Jan. 7, 1916, [Convention date]. Percussive hand tools.-In a fluid-operated hand-tool the valve 12 controlling the fluid supply is provided with radial passages 40, through which fluid can pass when the valve is only slightly depressed. The Specification as open to inspection under Sect. 91 (3) (a) describes a handle attachment in which the handle 1 is threaded on to the cylinder 2 and is locked by a ring 8, which is held to the handle by a snap ring 10, and has a projecting part engaging the handle to prevent relative rotation between them; a pin 9, fitted in one of a series of holes 39 in the cylinder and provided with an eccentric end 38 engaging one of a series of grooves 36 in the ring 8, prevents relative rotation between the ring and the cylinder. Fine adjustment is obtained by provision of the eccentric part 38, and unequal spacing of the holes 39 and grooves 36. This subject-matter does not appear in the Specification as accepted.
