602,186. Electric dryshavers. JAY, M. Sept. 10, 1945, Nos. 23303 and 23304. Convention dates, Sept. 13, 1944, and Aug. 2, 1945. [Class 131] An electric shaver for both shaving and cutting long hairs such as the moustache comprises a dome-shaped perforated guard 1 having completely around its periphery a ring 2 with slots 4 to form a comb. The guard 1 and ring 2 forming a unit are mounted on arms 5 forming part of a cage by which the head is secured to the body of the shaver. Two cutters 11 bear against the guard 1 and comb 2 and are mounted in inclined positions by means of arms comprising a member 14 pivoted on a transverse axis 17 and carrying another member 12 having a freely rotatable spindle with a ball head 16 which connects the cutter 11 to the member 12, a slot being formed in the member for the reception of the cutter 11 the arrangement being such that the cutter 11 adapts itself to the inner surface of the guard 1 being urged thereto by a spring 20 and centrifugal force. In operation the cutters 11 sweep over both the guard 1 and comb 2, a cylindrical cover 22 being provided to cover the comb 2 when it is not desired to cut long hairs the cover 22 being slidable on the arms 5. In a modification as shown in Fig. 3 the cutters 11 are not spring-urged but when not in operation rest on arms 24, centrifugal force urging the cutters 11 against the guard 1 when in operation. In addition these cutters do not reach the comb 2 two additional cutters 26 carried by arms 27 pivoted on a pivot 28 on the motor shaft, the arms 27 when the shaver is not in operation resting by means of slots 33 on the pivot pins 17 of the cutters 11, centrifugal force, when the shaver is in operation, causing the arms 27 to rise and consequently the cutters 26 to bear against the undersurface of the comb 2. As shown the cylindrical cover 22 may be retracted the distance X to uncover the comb 2 when it is desired to cut long hairs. By means of a ring 38 forming a cam a rod 41 may be caused to operate a switch when it is desired to operate the shaver on different voltages. |
