Abstract

The bore light includes a conductive shell that holds a battery and receives at one end a light bulb and at the other end a cap. The cap has a shaft which, upon being screwed into the cap, will press the battery against the bulb, thereby to cause the filament of the bulb to produce illumination.

Claims

1. A light for illumination of the bore of a gun, the light including the following elements:

a sleeve of a diameter less than the bore of the gun, the sleeve having a first end and a second end, the sleeve being sized to receive therein a battery having a conductive terminal at each end;

a light bulb having a filament therein for producing light when electric current passes therethrough, the light bulb having a threaded case electrically connected to one end of the filament and a central conductive button at the base end of the light bulb, the button being electrically insulated from the case and the button being electrically connected to the other end of the filament;

the sleeve having at the first end a threaded receptacle for receiving the threaded case of the light bulb with the conductive button positioned to engage one conductive terminal of a battery included in a case and to produce light at the first end of the sleeve,

means for selectively completing an electrical circuit between the battery and the light bulb, said completing means at least in part pressing the battery into engagement with the light bulb; and

a rubber bumper attached to and projecting beyond the second end of the sleeve and positioned to engage the breech mechanism after passage of the light through the gun'"'"'s bore,

whereby the bore light may be turned on by actuating the completing means and then caused to pass down the bore of a muzzle loading gun to illuminate it.

2. A light as set forth in claim 1 in which the sleeve is conductive and in which the completing means is attached to the sleeve at its second end.

3. A light as set forth in claim 2 in which the elements of the light are sized and positioned to not project laterally beyond the outer surface of the sleeve.

4. A light as set forth in claim 3 in which the completing means include first means providing a threaded internal bore at the second end of the conductive sleeve, a conductive shaft threadably received in the internal bore of said first means, the conductive shaft being sized, relative to the conductive sleeve and said first means, to upon being sufficiently threaded into the bore engage the second conductive terminal of the battery and complete the circuit to the case of the light bulb.

5. A light as set forth in claim 4 in which the first means is a threaded cap.

6. A light as set forth in claim 5 in which the rubber bumper is mounted on the end of the conductive shaft projecting beyond the conductive sleeve.

7. A light as set forth in claim 1 in which the size and outer surface of the sleeve is such that it does not harm the gun'"'"'s barrel during passage therethrough.
