Abstract

The invention relates to a flashlight that is adapted to be hand held and wherein the circuit to the bulb is completed by merely a squeezing action on the outer tubular shell of the container, which pressure causes a series of lengthwise metal fingers on a clip mounting the bulb, to be brought into contact with the metal can housing the battery and thus energize the bulb.

Claims

1. A flashlight including a battery, a bulb and an outer shell, said outer shell comprising a container for the battery and bulb, said battery being uninsulated with the metal can exposed throughout a major portion of its length, a generally cylindrical metal clip in the container surrounding the battery and having a plurality of spaced fingers extending lengthwise of the battery at spaced intervals around the battery, said container being flexible and made from a non-conducting plastic material, said container being compressible laterally to engage said metal clip and press one or more of said fingers into contact with said battery can to complete an energizing circuit to said bulb, a rear end cap or plug closing the rear end of the container, and a dielectric ring surrounding said battery which insulates a negative pole of the battery from said cylindrical metal clip, said battery supported at one end in said dielectric insulating ring and at its opposite end in said rear end cap, or plug.

2. A flashlight as set forth in claim 1 wherein said bulb is mounted in said clip and extends through the front end of said container, said bulb having a base structure in contact with an anode of said battery.

3. A flashlight as set forth in claim 2 wherein said container includes a resilient pressure device between the battery and the rear of the container, said device exerting axial pressure on the rear end of said battery, and which comprises a non-metallic bat of material under sufficient pressure to maintain said anode in constant contact with said bulb base structure.

4. A flashlight as set forth in claim 2 wherein said cylindrical clip includes one or more spring fingers surrounding and gripping said base structure to position the bulb in said container.

5. A flashlight as set forth in claim 3 wherein said non-metallic bat is disposed in said rear end cap, or plug and said plug incorporates an opening therethrough for suspension of the flashlight.
