Abstract
Abstract of the Disclosure This invention relates to gun sight lighting device and more particularly to an attachment that can be affixed to a gun sight to enable the gun and the sight to be used in situations where very little incidental light is present.
The attachment consists of a source of light that is attached to a gun sight of the type that operates on the principle of superimposing a sighting image on a target. The light source is directed specifically at illuminating the object that is used to develop the sighting image so that the gun sight can be used in conditions where the level of incidental light present is insufficient to enable the sighting image to be readily seen by the user of the sight, but the level of incidental light is sufficient to permit the target to be seen by the user of the sight.

Description
GUN SIGHT NIGHT LIGHTING ATTACHMENT
This invention relates to gun sight lighting device and more particularly to an attachment that can be affixed to a gun sight to enable the gun and the sight to be used in situations where very little incidental light is present.
BACKGROUND OF THE INVENTION
Many modern gun sights employ a prism and/or mirror reflecting system whereby the user of the gun looks through the sight and sees an optical sighting image superimposed upon the target. A gun sight of this nature is fully described and claimed in U.S. Patent No. 3,439,970. A gun sight using an optical image is available on the market and is known as the Weaver "Qwik-Point"* sight, Model R-l, U.S.A.
Another type of gun sight is designed to permit the user of the gun to use both eyes in lining the gun up with the target. One eye is used to look through the sight ~-,.. .
and the other is used to look alongside the sight at the target. The brain of the user then collates the two images -seen by the two eyes to assist in lining the gun up with the target.
Essentially, the Weaver "Qwik-Point"* sight presents to the viewer a spot or dot sighting image which is developed ;by~means~of a thin red, or similarly coloured, glass or transparent plastic rod, such as "LUCITE"*, which is located in~a~horizontal posit~ion parallel to the barrel of the rifle within a~transparent glass or plastic housing at the front o the sight. This thLn~glass or plastic rod, located inside the~transparent plastic housing, collects daylight and 30~ ~transmLt~s;~it through the end of the rod nearest the viewer.
Th~end of the rod is then seen by the viewer by means of a~se;rLes of~ pr1sms and mirrors which superimpose the image of the rear tip of the rod in the centre of a tube that is located below the chamber that houses the thin glass or *Trade marks .' ~
plastic rod and the transparent housing. The effect of this rod tip imaging system is that when the viewer sights through the lower tube, which is located immediately above the rifle, the viewer sees a red or similarly coloured dot superimposed upon the target. The dot represents the path along which the bullet will travel when the rifle is fired. To use the sight in combination with the rifle, the user of the rifle lines the rifle up with the intended target by sighting through the tube and superimposing the red or similarly coloured dot on the target area which he intends to hit with the bullet.
The Weaver "Qwik-Point"* sight is very useful during the day when there is substantial incidental light about because it enables the user of the rifle to position the image spot on the target quickly and thereby line the rifle up with the target quickly. However, as the amount of incidental light decreases, it becomes increasingly difficult fcr the viewer to see the red or similarly coloured dot superimposed on the target. Consequently, the Weaver "Qwik-Point"* sight is less than ideal in relatively dark conditions.
To enable the Weaver "Qwik-Point"* sight, and other gun sights which operate on a similar image superimposing principle, to be used in conditions where there is very little incidental light present, I have invented an attachment which astens readily to the sight and enables the sight to be used in almost all conditions of light. The only requirement is that there must be sufficient incidental light present to permit the target to be seen by the user of the sight. Since there are very few situations where the target is not illuminated by incidental light to the point that it can be seen dimly, my attachment greatly increases the usefulness of the Weaver "Qwik-Point"* sight, and other similar sighting devices.

As seen in Figure 2, the interior surface 3 of the fitting 1 is machined to close tolerances so that it ~20 fits snuggly but detachably about the front end of the Weaver "Qwik-Point" sight 4.

~068245 projection 6 is of a narrower diameter than the diameter of the gun sight fitting 1 and is positioned so that its centre line aligns with the centre line of the gun sight fitting 1.
Machined in the cylindrical projection 6 along the centre line is a cylindrical opening 8. This cylindrical opening 8 is of a smaller diameter than the cylindrical projection 6.
The exterior of the battery holder 2 has a generally tapering or telescoping shape. The battery holder is open at one end. In the embodiment shown in Figures 2 and 4, the exterior of the battery holder 2 is constructed in the form of a series of adjoining cylinders all having a common axis and increasingly smaller diameters until the closed end 9 ~
of the battery holder 2 is reached. -The interior of the battery holder 2 is hollow and ~-machined to different diameters in order to form a battery `
receptacle 10 and a larger diameter light bulb receptacle 11.
The battery receptacle 10 and the light bulb receptacle 11 are substantially cylindrical in shape and have a common axis with the axis of the battery holder 2. The light bulb`
2~ receptacle 11 has female threads 12 machined about its circumference closest to the open end of the battery holder 2.
The female threads 12 are machined to coordinate with and be of approximately the same diameter as the male threads 7 of the gun sight fitting 1. By means of the similar dimensions ~ .
of the female threads 12 and the male threads 7, the gun sight fitting 1 can be screwed into the battery holder 2. Of course, other methods rather than threads, for example, inter-locking slots, can be used to provide a secure readily discon-nectable joint between the gun sight fitting 1 and the battery holder 2.
When the gun sight fitting 1 is screwed into the battery holder 2, the cylindrical opening 8, the battery receptacle 10, and light bulb receptacle 11, provide a chamber which is large enough to hold a light bulb 13, a light bulb holder 14, and a battery 15 (See Figure 2). To ~0~;8245 keep the dimensions of the gun sight fitting 1 and the adjoining battery holder 2 relatively small, it is preferable that the light bulb 13 and the battery 15 be of pen-light size. However, it will be recognized that other light source generating devices can be used.
The light bulb 13 is held in place by the light bulb holder 14. This holder 14 may be of many suitable constructions such as a coil spring that surrounds the base -of the light bulb 13, or a small cylindrical holder stampèd out of metal sheet or constructed of plastic. The function of the light bulb holder 14, or variant thereof, is to keep the light bulb 13 centred more or less on a line with the axis of the battery holder 2.
A battery spring 16 is positioned at the bottom of the battery receptacle 10 between the closed end 9 of the battery holder 2 and the battery 15. The function of this battery spring 16 is to apply pressure to the base of the battery 15 so that the battery 15 remains in close electrical contact with the base of the light bulb 13. Of course, other suitable ohvious devices may be used in place of the battery spring 16, so long as they operate to keep the battery 15 in electrical contact with the base of the light bulb 13.
:
The light bulb 13 can be turned on or off by rotating the battery holder 2 in relation to the gun sight flttLng l about the respective male threads 7 and female threads 12. By rotation in this manner, the distance between contact point 17 of the gun sight fitting 1 and contact point L8 of the battery holder 2 can be varied. By shortening ;the~dlstance between the contact points 17 and 18, and indeed 30~ bringin~g~them tQgether~ the battery 15 is brought into contact with the base of the light bulb 13, which is held in place by the light bulb holder 14 against the end of the cylindrical :
~ 6 -.
projection 6. An electrical current then passes from the battery 15 to the light bulb 13 thereby lighting the light bulb 13.
When it is desired to turn off the light bulb 13, the battery holder 2 is rotated several turns counter-clockwise in relation to the gun sight fitting 1. This rotation lengthens the distance between contact points 17 and 18 until electrical contact between the light bulb 13 and the battery 15 is broken. In that position, no electrical current passes from the battery 15 into the light bulb 13 and the light bulb 13 is not lit.
While the foregoing method of turning on and off the light bulb 13 is shown in the drawings, it will be readily recognized by anyone considering the construction of the attachment that an electrical switch, or other suitable on-off mechanism, can be installed on or in the battery holder 2 to turn the light bul~ 13 on or off.
In order to tell when the light bulb is on or off, it is preferable to have a small observation hole 19 drilled in the sid of the gun sight fittingl. The size of this observation hole 19 should be sufficiently large so that it can be readily seen whether the light bulb 11 is on or off.
:
But at the same time, the observation hole 19 should not be so;large that a sizeable amount of light from the light bulb 11 will escape through the observation hole 19. Too much light will annoy or distract other members of any group in which the person carrying the gun might be a member, or, when ` co;ndltions~are relatively dark, betray the position of the perso~n~ carrying the gun. Concealing the position of the person carrying the gun might be important in hunting, war or police work situations. I have found that an observation hole of ap~oximate~y l~l~ inch diameter is suitable.

10~245 If the light bulb 13 were permitted to shine unimpeded upon the glass or transparent plastic rod 20 of the Weaver "Qwik-Point"* sight 4, a distracting halo surrounding the image of the rod would be presented to the viewer. It is therefore important that the light is permitted to shine directly on only the end of the rod 20. In this way, a distinct point of light from the end of the rod 20 is presented to the viewer. To meet this requirement and eliminate the halo, I have found that an opaque disc 21 with a pin hole 22 drilled through the centre of it can be installed in the interior of the gun sight fitting 1 adjacent the closed end 5. The diameter of the disc 21 coincides with the diameter of the interior surface 3 of the sight fitting 1 so that the disc 21 fits snuggly inside the interior surface 3 adjacent the closed end 5. A linear pin hole 22 is machined along the circumferential axis of the disc 21 so that it meets and aligns with the end of the rod 20. I have found that a hole of 1/32 inch diameter permits the proper amount of light from the light bulb 13 ~o to reach the end of the rod 20 so that the image 23 (See Figure 3) presented to the viewer is of maximum intensity, yet is not surrounded by an annoying halo from the light bulb 13.
It should be kept in mind that it is not necessary to have the dlsc 21 and linear pin hole arrangement as a separate element in the gun sight fitting 1. The con-struction of the gun sight fitting 1 can be designed so that a predetermined width of metal will lie between the light bulb 13 and the rod 20, and that apin hole,or some other light transmitting aperture, can be machined in this width of metal. Accordingly, the disc 21 and pin hole 22 should be regarded only as a preferred embodiment. The *Trade mark .
