Abstract
Abstract An aiming light and an aiming light adapter combination moulded together wherein the aiming light adapter is connected to a weapons adapter, which is in turn locked onto a weapon. A projecting lens is held within the forward end of the aiming light housing by a lens retainer having a transparent window. A removable screw threaded end cap on the back portion of the aiming light housing is used to tighten down on a dry cell battery and an electronic pulser canister. The canister and battery fit snugly around the inside of the aiming light housing with a beveled front end of the canister pressed up against a beveled canister retainer when the end cap is tightened. The beveled canister retainer has a circular aperture through which a light emitting diode, attached to the canister, is passed. The diode is electrically connected to the output of the electronic pulser circuitry. The output light beam from the diode is aligned along the optical axis of the aiming light since the beveled canister retainer prevents any traverse motion of the canister. The aiming light adapter has horizontal and vertical adjusting and locking means for positioning the aiming light beam with respect to the bore alignment of the weapon. The aiming light beam may be of the invisible infrared spectrum for observation by an operator at nighttime when using an infrared sensitive image intensifier, or the aiming light beam may be visible and be observed either at night or during the day be the naked eye.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
263 words
An aiming light for aiming a small caliber weapon comprising: an aiming light housing comprising a projecting lens held in the forward end of said housing by a transparent window lens retainer and a screw threaded end cap threadably connected on the back end of said housing; a light emitting means within said housing wherein said light emitting means comprises a dry cell battery positioned adjacent said cap, a canister containing an electronic pulser circuit having a beveled outer edge at an output end which fits snugly against a beveled canister retainer connected to said housing adjacent said projecting lens and an input end adjacent to and in electrical contract with one terminal of said battery, and circuit means including an electrical contact mounted on said cap for electrically connecting the other terminal of said battery with the input end of said canister retainer, with said output end having a light emitting diode therein whereby tightening of said cap on said housing completes the circuit between said battery and said input end of said canister, causing a pulsing light beam to be emitted from said light emitting diode; and an aiming light adapter attached between said weapon and said aiming light housing, said adapter comprising a vertical adjusting means and a horizontal adjusting means wherein said vertical adjusting means is connected to a moulded portion of said aiming light housing and positions said pulsing light beam in the vertical direction and wherein said horizontal adjusting means is connected to said vertical adjusting means and positions said pulsing light beam in the horizontal direction.
Claim 2
Dependent Claim
263 words
An aiming light for aiming a small caliber weapon comprising: an aiming light housing comprising a projecting lens held in the forward end of said housing by a transparent window lens retainer and a screw threaded end cap threadably connected on the back end of said housing; a light emitting means within said housing wherein said light emitting means comprises a dry cell battery positioned adjacent said cap, a canister containing an electronic pulser circuit having a beveled outer edge at an output end which fits snugly against a beveled canister retainer connected to said housing adjacent said projecting lens and an input end adjacent to and in electrical contract with one terminal of said battery, and circuit means including an electrical contact mounted on said cap for electrically connecting the other terminal of said battery with the input end of said canister retainer, with said output end having a light emitting diode therein whereby tightening of said cap on said housing completes the circuit between said battery and said input end of said canister, causing a pulsing light beam to be emitted from said light emitting diode; and an aiming light adapter attached between said weapon and said aiming light housing, said adapter comprising a vertical adjusting means and a horizontal adjusting means wherein said vertical adjusting means is connected to a moulded portion of said aiming light housing and positions said pulsing light beam in the vertical direction and wherein said horizontal adjusting means is connected to said vertical adjusting means and positions said pulsing light beam in the horizontal direction.
Claim 3
Dependent Claim
426 words
An aiming light as set forth in claim 1 wherein said vertical adjusting means and horizontal adjusting means comprise: a vertical housing plate having a horizontal pivot hole on the back part thereof through which a horizontal pin extending from the back section of said moulded portion fits; a vertical boresight adjusting knob and stem, said stem having a smooth portion at its end and threaded portion adjacent said knob with a notched groove between said smooth and threaded portions wherein said stem is threaded through a front section of said moulded portion in a direction perpendicular to said horizontal pin and said smooth portion is seated and held in a front part of said vertical housing plate by a pin fitted in said notched groove; a vertical locking screw having a head resting against said vertical housing plate and a stem loosely fitted through the front part of said vertical housing plate and screw threaded into the front section of said moulded portion; a groove portion adapted for connection to a tongue portion on said smaller caliber weapon, said groove portion having a vertical pivot hole in the mid part thereof through which a pin extending from said vertical housing plate fits; a horizontal boresight adjusting knob and stem, said stem having a threaded portion adjacent said knob that is threaded through said back part of said vertical housing plate and a smooth portion at the end of said stem with a notched groove betweEn said threaded and smooth portions wherein said stem is seated and held in the back portion of said groove portion by a pin fitted in said notched groove; and a horizontal locking screw having a head resting against and a stem loosely fitted through the back part of said groove portion and screw threaded into the back part of said vertical housing plate whereby rotation of said horizontal boresight adjusting knob and stem screw threads said stem through the vertical housing plate to pivot the optical axis of said housing in the horizontal direction about a vertical axis and said horizontal locking screw locks said vertical housing plate to said groove portion after alignment of said optical axis in the horizontal direction and whereby rotation of said vertical boresight adjusting knob stem screw threads said stem through the moulded portion to pivot the optical axis of said housing in the vertical direction about a horizontal axis and said vertical locking screw locks said moulded portion to said vertical housing plate after alignment of said optical axis in the vertical direction.
Claim 4
Dependent Claim
41 words
An aiming light and aiming light adapter as set forth in claim 11 wherein said projecting lens is a double-convex 21 millimeter diameter single lens that narrows the beam width of said aiming light beam emitted from said light emitting diode.
Claim 5
Dependent Claim
24 words
An aiming light and aiming light adapter as set forth in claim 3 wherein said light emitting diode is an electron injection laser diode.
Claim 6
Dependent Claim
27 words
An aiming light and aiming light adapter as set forth in claim 4 wherein said electron injection laser diode is a gallium aluminum arsenide single heterojunction chip.
