Abstract
Abstract An electric flashlight having independently operable continuous and blinker bulbs mounted at opposite ends of a tubular barrel. A contact assembly is removably located at one end of the barrel and has two coaxially arranged contact elements. The first contact element rests on the edge of the barrel and a blinker bulb electrically connects the first contact element to the second contact element. Two separate switches are mounted for controlling the bulbs.

Claim 1
Independent Claim
260 words
An electric flashlight comprising a battery-holding tubular barrel, a contact assembly removably located at one end of the barrel, wherein the contact assembly comprises first and second stacked coaxially arranged contact elements of substantially circular configuration and an insulating separator between the said first and second contact elements, the first contact element being outermost and having a peripheral border resting on one edge of the torch barrel and being adapted to receive a first bulb for electrically connecting the first contact element to the second contact element, a spring member for engaging one terminal of a battery when in the tubular barrel, the spring member being fixed to the insulating separator and being electrically insulated from the second contact element but electrically connected to the first contact element, a first switching member for selectively connecting the second contact element to the other terminal of a battery when in the tubular barrel, means for receiving a second bulb for electrical contact with the said other terminal of a battery when in the tubular barrel, a second switching member for selectively connecting the second bulb when in the said means for receiving a second bulb to the said first contact element, the said spring member being a flat Z-shaped strip of conducting material, the said spring member having at least one cutout portion, and the said insulating separator having at least one slit receiving the said at least one cutout portion of the said spring member, one of the said at least one cutout portions electrically contacting the said first contact element.
