OECNL'H 210cm KP? Eal28a52 Aug. 30, 1938. F. M. ESLICK FIREARMS SIGHTING DEVICE File d March 26, 1936 Patented Aug. 30, 1 93s untrue sr 'ras PATENT OFFICE 7 Claims.
This invention relates to firearms, and more particularly to a sighting means therefor.
An object of this invention is to provide an attachment which may be applied to various types of firearms which will facilitate the firing of the firearms at night or in the dark.
Another object of this invention is to provide an attachment of this character which is so constructed that relatively accurate firing is possible at night or in dark places without sighting along the barrel of the gun or firearm to which the device is attached. 7
A further object of this invention is to provide an attachment of this character which will light up the object at which the gun or firearm is pointed, the lighting equipment including means for determining the spot where the bullet will strike.
Still another object of this invention is to provide an attachment of this character which may be quickly and easily mounted on the barrel of the firearm without changing any of the present parts thereof and which may be quickly removed therefrom so that the one firearm may be used in either light or dark places.
With the foregoing and other objects in View, the invention will be more fully described hereinafter, and will be more particularly pointed out in the claims appended hereto.
In the drawing, wherein like symbols refer to like or corresponding parts throughout the several views:
Figure 1 is a detail side elevation of a gun sighting attachment mounted on a rifle pointed at a target which is shown in perspective.
Figure 2 is an enlarged longitudinal section of the sighting attachment.
Figure 3 is a sectional view taken on the line 3--3 of Fig. 2.
Figure 4 is a fragmentary top plan of the device.
Figure 5 is a sectional view taken on the line 5--5 of Fig. 2.
Referring to the drawing, wherein like symbols refer to like parts throughout the several views, the letter B designates generally the barrel of a gun, which may be a. rifle, pistol or. other form sight S on the upper side thereof at the forward end which isused in the use of the gun when sighting along the barrel B is possible, as in daylight.
In order to facilitate the accurate shooting by law enforcement officers, watchmen, or the like in the apprehension of criminals I mount a spot light on the top of the barrel B which comprises a casing having a threaded cylindrical rear portion ll and an enlarged partially threaded forward portion Ill. The reduced. and threaded rear portion H is threaded onto a cup-shaped base'member I4 which is secured as by screws l3 or like fastening elements to the upturned rear end i of an elongated base bar I B.
The base member M has a sleeve I'l disposed therein which extends axially into the reduced portion H and constitutes a guide for a socket holding sleeve l8. The sleeve 18 is held against movement in the socket or fixed sleeve ll by means of a screw l9 or the like. A light socket 20 including a threaded metal shell 2i and, an insulated end wall 20 is fixed as by soldering to the adjustable sleeve l8, and the plug portion of a light bulb 22 is adapted to be threaded into win the socket 20 and is held against displacementdue to the concussions or other vibrations to which the gun barrel B is subjected during the handling or firing thereof by means of a screw 23 which extends through the adjustable sleeve 18 inwardly of the inner end of the sleeve IT.
A light reflector 24 is disposed in the enlarged forward end of the casing l0 and is provided with a relatively large central opening through which the light bulb 22 loosely projects in order to permit adjustment of the reflector 24 relative to the light bulb by threading the reduced rear portion H either forwardly or rearwardly. A bezel 25 receives the flanged outer edge of the reflector 24 and a lens 26 is mounted in the bezel and engages against the forward end of the reflector 24. The reflector 24 is preferably of the type which will spread the light rays from the light source over a fairly large area, but of course this area may be reduced or enlarged by forward or rearward adjustment of the reflector so that the desired spread of light is obtained at the desired distance forwardly of the spot light.
A light ray concentrating lens 21 is disposed forwardly of the spot light hereinbefore described and is so positioned as to have the lower light rays from the spot light which are projected in a plane parallel with the longitudinal axis of the barrel B pass therethrough. In other words, the
reflector 24 and the light bulb 22 will light up a circular area substantially above the longitudinal axis of the gun barrel B with a small portion of the lighted area slightly-below the point at which a bullet fired from the barrel B will strike an object. The light ray concentrating lens 21 will describe a relatively small circular lighted area, the'center of which is so adjusted for efiective range as to be slightly below the point at which the bullet will strike the object.
The light ray concentrating lens 21 is mounted in a bezel or frame 28 secured to a bar 29, and the bar 29 is provided with a flat lower portion 30' which is adapted, when the lens 27 is in operative position, to engage the upper side of the supportingbar IS. A spring or resilient strip, Si is secured adjacent one end to the. bar
l6 and is provided at the opposite end with a slot 32 in which the lower end of the supporting bar 29 is received, and the opposite or forward end of the strip 3| has a hinge barrel 33 through which a pintle 34 extends, the pintle 34 also extending through an opening in the lower por tion of the bar 29. This resilient strip 3i will maintain the ,lens supporting structure, including the bar 29 and the bezel 28 in either upright operative position or in inoperative position, the latter position being shown in dotted lines in Fig. 2;
The forward end or the supporting bar i6 is provided with a hinge barrel 35 which engages between a pair of ears 35 carried by the upper side or bight of a clamping member generally designated as 31. A pintle 33 engages through the cars 36 and the barrel 35 so as to swingably the supporting bar on the clamping member 31. .4. rear substantially U-shaped clamping member 39 is secured to the rear portion of the supporting bar l6 and removably secures the rear portion of the bar 15 onto the barrel 5.
The forward clampin-g member 3? comprises an outer substantially U-shaped member 40- which is' fixed to the base portion 4i of the cars 35, and an inner segmental barrel engaging mem ber 42 which is substantially larger than a half circle so as to snugly engage about'the periphery of the barrel B. The forward end of the inner clamping member 42 is provided with a forwardly opening slot 43 in which the sight S engages, and a screw- 44 is threaded through the outer clamping portion 40 and engages against the bight of the inner clamping member 42 so as to tension the clamping member 37 on the barrel B and thus prevent movement of the bar IS when the barrel B recoils.
A conductor 45. including two wires is provided at one end with a plug 45 which may be threaded into the conventional light socket provided in spot lights, and the other-end of the conductor 45 is connected to the socket 20 and to a central contact 41 which is engaged by the central terminal or contact of the light bulb 22. It will, of course, be understood that any suitable means may be provided for conveying electric current to the light bulb 22 and that if desired light cells may be incorporated directly in the casing I.
In the use of this sighting attachment, the plug 46v is first connected to the source of'current supply so as to light up the bulb 22, and the clamping members 31 and 39 are mounted on the barrel B in a manner to position the bar [5 on the top thereof with the sight S disposed ln the slot 4| of the clamping member 42. The screw 44 may thenv be tightened so as to firmly clamp the bar l6 onto the barrel B. When once adjusted to a particular gun barrel the screw 44 need not be further adjusted. The lens support 28- 29 is then raised as. shown in full lines in Fig. 2, and with the light bulb 22 lighted, the gun barrel B is pointed at the desired object. The'major portion of the light rays emanating from the light source 22 and the refiector 24 will light up the object at which the gun is pointed, the rays being spread over the desired area by adjustment of the casing l0 relative to the support 14. The lower rays passing through the lens 21 will define a relatively small and bright area within the field of the major light rays, and this bright area is adjusted to locate the spot where the bullet from the barrel B will strike so that the bullet will strike the bright area in the upper portion thereof.
It will be apparent from the foregoing that an efficient and relatively accurate sighting attach ment has been provided which may be mounted on gun barrels of various types, and that it is only necessary for the user of the device to locate the lightly defined area within the field of the spot light to determine the exact spot where the bullet will strike the object at which the barrel B is aimed.
It is obvious that various changes and modifications may be made in the details of construction and design of the above specifically described embodiment of this invention'without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the followingclaims.
