摘要：981,076. Dry Shavers. SPERRY RAND CORPORATION. Jan. 3, 1963 [Jan. 12, 1962],No. 367/63. Heading B4B. [Also in Division H2] In a dry shaver having a casing 11 in whichare located a D.C. motor 13, means for holding batteries 119 for driving the motor and aswitch having an actuating member which is accessible from the exterior of the casing toconnect the batteries to and disconnect them from the motor, a stator 15 and rotorarmature 21 are mounted in upper and lower members 51, 53 which are interconnectedby means of posts 89 and support clamping means 125, 127 for detachably holding thebatteries, the switch being detachably supported by the member 53. The posts 89 areintegral with member 53 and are secured to member 51 by means of screws 85, Fig. 2.The motor is energized through brushes 101, 103 which are slidably disposed inpassageways in member 53 and are spring-biased into engagement with a commutator29. The switch is selectively settable to connect the motor to the batteries or to

terminals 121, 123, Fig. 3, adapted for connection to an external D.C. source. The terminalsare mounted on a board 165 on which are also mounted stationary contacts 167, 169 and

a movable contact 171 which has spaced leaf-spring contacts 173, 175. A contact actuator181 is rotatably carried by the board 165 and is manually positioned by means of amember 183. A cam 193 secured to actuator 181 is arranged so that when rotatedcounterclockwise it causes contact 173 to engage contact 167 and contact 175 to detentthe actuator and when rotated clockwise it causes contact 175 to engage contact 169and contact 173 to detent the actuator. The board 165 has apertures 209 which are afriction fit on lugs 211, Fig. 2, at the ends of posts 213 of member 53 and is detachablysecured to posts 215 on member 53. Battery holding assemblies 125 each have a rivet(145, not shown) for contacting a top cap of a battery and prongs 131 for engaging thesides of the battery. Each assembly 125 also has a clip 139 with portions 141 and springportions 143 engageable with a ledge 155 and lugs 157, 159 on member 51. Member 53has integral resilient arms 127 for supporting the batteries.
