Abstract

352,975. Safety razors. THOMPSON, R. E., 428, Warren Street, Brookline, Massachusetts, U.S.A. April 15, 1930, No. 11964. Convention date, April 25, 1929. [Class 30.] In a safety razor of the kind wherein a thin blade 22 is flexed around a cylindrical supporting guard-plate by pressure near its edges of an internally concave cap 10, uneven clamping due to accidental deformation of the cap corners is prevented by so shaping the blade that the corners of the cap do not exert any pressure on it. For this purpose the blade has cut-away corners 25. The medial part of the blade is extended beyond the cap to prevent cracking and to facilitate handling. The guard may have longitudinal channels underlying the blade edge as described in Specification 133,963, [Class 30, Cutlery]. There are aligning pins 16 and a clamping pin 17 engaged by a nut fitting freely within a tubular handle fixed to the guard-plate. The Specification as open to inspection under Sect. 91 (3) (a) states also that the corner recesses 25 may be engaged by corner projections 37, Fig. 5 (Cancelled) on the cap which reinforce the cap, against deformation. The projections may be of less thickness than the blade, or of greater thickness in which latter case they project into the guard channels 21 above referred to. They are preferably integral with the cap and taper inwardly flush with its ends. This subject-matter does not appear in the Specification as accepted.
