  • Flashlight having resilient sleeve
    Patent number: 5601359
    Abstract: A flashlight is provided with a conductive casing and a resilient sleeve positioned on the conductive casing. The sleeve is mounted on the casing by conducting a flow of pressurized gas through the casing, aligning the sleeve with the rear end of the casing to inflate the sleeve, and then urging the sleeve onto the casing. The sleeve is configured to expose the forward end of the casing, which is threaded to rotatably engage a head assembly. The head assembly includes a spring positioned therein for mounting a conductive rim of a lamp socket in abutment with the forward end of the casing.
