Abstract
Abstract An elongated tubular body constructed of conductive material is provided and includes open front and rear ends. A combined reflector and lens assembly is supported from the front end of the body and a bulb is removably supported from the reflector and lens assembly and includes center and base terminals with the base terminal electrically connected, by the reflector and the lens assembly, to the body and the center terminal supported out of electrical connection with the body. Battery structure is slidably disposed within the body and includes a forwardly facing forward terminal in electrical contact with the center terminal of the bulb and a rearwardly facing rear terminal. A thick walled sleeve is disposed and longitudinally slidable in the rear end of the body and is constructed of deformable, resilient dielectric material. The front end of the sleeve includes a contact electrically contacting the rear terminal of the battery structure and a thrust member is mounted in the rear end of the body behind the sleeve for adjustable positioning therealong to variably bias the sleeve and thus the battery, forwardly in the body. The thrust member is constructed of conductive material and is in electrical contact with the body. A switch structure is supported from the thrust member and includes a switch actuator therefore disposed in recessed position within the rear end of the body and operable from the exterior thereof. The switch defines a ground terminal which is grounded to the thrust member and a second terminal which is insulated relative to the thrust member and disposed within the interior of the sleeve. A conductor wire is connected between the second terminal of the switch and the contact carried by the front end of the sleeve.

A battery actuated flashlight including an elongated tubular body having open front and rear ends, said body being constructed of conductive metal, a combined reflector and lens assembly supported from the front end of said body, a bulb including center and base terminals removably supported from said reflector and lens assembly with said base terminal electrically connected, by said assembly, to said body and said center terminal out of electrical connection with said body, battery means slidably disposed in said body including a forward facing forward terminal in electrical contact with said center terminal and a rearwardly facing rear terminal, a thick walled sleeve disposed and longitudinally slidable in said rear end of said body and constructed of deformable and resilient dielectric material, a conductive contact disk slidable in said body and disposed across the front end of said sleeve defining a contact electrically contacting said rear terminal, a thrust member threadedly mounted in the rear end of said body and adjustable positioning therealong for variably axially compressing and biasing said sleeve, and thus said battery, forwardly in said body, said thrust member being constructed of conductive material and being in electrical contact with said body, and switch means supported from said thrust member and including a switch actuator therefor disposed in recessed position within said rear end of said body and operable from the exterior thereof, said switch means defining a ground terminal therefor grounded to said thrust member and a second terminal insulated relative to said thrust member and disposed within the interior of said sleeve, and means within the interior of said sleeve electrically connecting said second terminal to said contact, said switch means being secured through a central portion of said thrust member and said actuator comprising a portion of said switch means projecting rearwardly of said thrust member into the rear end of said sleeve.
Claim 3
Dependent Claim
40 words
The combination of claim 1, including a dielectric protective sleeve snugly telescoped within said body forward of said thrust member and extending forwardly to a point adjacent said assembly, said battery means being slidingly received in said dielectric protective sleeve.
Claim 4
Dependent Claim
219 words
A battery actuated flashlight including a hollow body defining first and second openings opening thereinto, a bulb supporting combined reflector and lens assembly removably closing said first opening, battery means in said body and removably therefrom through said second opening, a closure for said second opening for retaining said battery means in said body, said closure being removably supported from said body in recessed position relative to the outermost extremity of said second opening, said battery means and body including means defining an electrical circuit for electrically connecting said battery means to said bulb for electrical actuation of the latter, said circuit defining means including a manually operable switch serially connected in said circuit and supported from said closure in fully inwardly recessed position relative to the outermost extremity of said second opening and including an operator manually operable by digital manipulation from exteriorally of said second opening, said body comprising an elongated tubular body having front and rear ends, said first and second openings opening outwardly of said front and rear ends, respectively, said closure comprising a closure body removably threadedly supported within the rear end of said tubular body centrally through which said switch is ecured, said operator being disposed rearwardly of said closure body and fully recessed within the rear end of said elongated tubular body.
Claim 5
Dependent Claim
219 words
A battery actuated flashlight including a hollow body defining first and second openings opening thereinto, a bulb supporting combined reflector and lens assembly removably closing said first opening, battery means in said body and removably therefrom through said second opening, a closure for said second opening for retaining said battery means in said body, said closure being removably supported from said body in recessed position relative to the outermost extremity of said second opening, said battery means and body including means defining an electrical circuit for electrically connecting said battery means to said bulb for electrical actuation of the latter, said circuit defining means including a manually operable switch serially connected in said circuit and supported from said closure in fully inwardly recessed position relative to the outermost extremity of said second opening and including an operator manually operable by digital manipulation from exteriorally of said second opening, said body comprising an elongated tubular body having front and rear ends, said first and second openings opening outwardly of said front and rear ends, respectively, said closure comprising a closure body removably threadedly supported within the rear end of said tubular body centrally through which said switch is ecured, said operator being disposed rearwardly of said closure body and fully recessed within the rear end of said elongated tubular body.
