Abstract

220,623. Metropolitan-Vickers Electrical Go.. Ltd., (Assignees of Trotter, H. R., and Schmidt, H. F.). Aug. 13, 1923, [Convention date]. Void [Published under Sect 91 of the Act]. Blades having forked roots are secured in the blade-holding groove by a wedge adapted to be driven longitudinally of the groove, and, alone or in conjunction with another wedge, to expand the forced root into contact with the walls of the groove. Thus, Fig. 1, a wedge 18 driven longitudinally of the groove 11 in the blade-carrying element 10 forces upwardly a wedge 17 so as to spread the forked root 14 of the blade 13. Fig. 2 shows a wedge 22 co-operating with a wedge 21 in the converging recess 20 between the blade shanks. A single wedge 36, Fig. 4, may be driven into a tapered recess 35 at the bottom or top of a recess 23 between the blade shanks, or such a wedge 51, Fig. 7, may co-operate with another wedge 50, the blade root and the groove walls being shown serrated in this modification. A compound wedge 42, 43, Fig. 6, may also be used.
