This invention relates to new and useful improvements in gun sights and the primary object of the present invention is to provide an illuminated gun sight so designed as to facilitate the same to be applicable for use in lining up a fast moving target such as deer, game birds, rabbits or the like in a convenient manner.

Another important object of the present invention is to provide an illuminated gun sight that is quickly and readily applied to or removed from a gun barrel, rifle or the like to permit a user to line up a target under poor lighting conditions.

A further object of the present invention is to provide an illuminated gun sight which is extremely small and compact in structure and which includes novel and improved means for making and breaking a circuit to energize or deenergize a bulb that is employed for lining up a target.

A still further aim of the present invention is to provide an illuminated gun sight that is simple and practical in construction, strong and reliable in use, neat and attractive in appearance, relatively inexpensive to manufacture,. and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 11 is a front elevational view of Figure 10.

Referring now to the drawings in detail, wherein for the purpose of illustration, there is disclosed a preferred embodiment of the present invention, the numeral It represents a tubular battery holder internally threaded at each end to receivably engage a pair of closure plugs l2 and I4. Slidably positioned in the battery holder I0, is a pair of preferably fibrous washers I6 and I8 between which there is disposed a pair of batteries 20 and 22. Frictionally positioned in a central bore 24 provided in the closure plug l2 and the opposed openin 26 provided in the washer I6, is one end 28 of an insulated conductive wire 30 having a contact tip 32 that frictionally engages the terminal 34 of the battery 20.

Adjustably mounted in an internally threaded bore 36 provided in the closure plug 14, is a threaded ground rod. 38 having a knurled surfaced head portion 40. Biased between the closure plug 14 and the washer I8, is a coil spring 42 that urges the terminal 44 of the battery 22 into contact with the base of the battery 20.

Frictionally engaging the upper periphery of a gun barrel 46, is the lower concaved portion 48 of an elongated substantially rectangular anchor member 50 having a concaved upper portion 52 and a transverse notch 54.

The numeral 56 represents the attaching brackets used in conjunction with the present invention generally, each of which includes a lower loop 58 that friotionally embraces the holder ID, a pair of split upper loops 6!! that embrace the gun barrel 46, opposed attaching ears 62 connecting the lower loop 58 to the upper loops 60, and a pair of opposed outer ears 64 extending outwardly from the upper loops B0. The attaching ears 62 are adjustably connected by fasteners 66 and the attaching cars 64 are removably secured by fasteners 68 to the sides of the anchor member 50.

Frictionally positioned in the concaved portion 52 of the anchor member 50, is the lower periphery of a bulb housing or chamber 10 having an internally threaded forward end that receivably engages the reduced threaded end 12 of a closure plug 14 which frictionally engages the forward end 16 of the anchor member 50. Positioned in the housin 70, is a flash light bulb 18, the threaded portion Bil of which is frictionally embraced by a split ring 82 that frictionally engages the inner periphery of the housing 70 to retain the bulb 18 within the housin I0. Slidably mounted in the housing 10, is a preferably fibrous washer 84 which frictionally supports the free end 86 of the conductive wire 30 that extends through an inlet opening 88 provided in the closure plug 14. Biased between the closure plu 14 and the washer 84, is a coil spring 90 that urges the contact tip 92 of the end 86 into frictional engagement with the contact tip 94 of the bulb I8.

Removably secured to the housing by any suitable means, is a retaining ring 95 having an arcuate, integral shield 96 which projects upwardly from the upper periphery of the housing I0. This shield 96 is provided with an integral closure plate 98 that opposes the bulb I8 and which is formed with a light emitting opening I00. Bendable tabs I02 carried by the plate 98 are turned inwardl to frictionally support a suitable colored lens or plate I04 that registers with the openin I00.

Removably positioned between the inner walls of the retaining ring 96, is a light reflector which is designated generally by the numeral I 06. This reflector includes an arcuate strip I08 having a central opening I I0 that frictionally engages the reduced tip and H2 of the bulb I8. One end II4 of the strip I08 is turned upwardly to space the tip end II2 from the plate 98. Integrally formed with the strip I08, is a pair of arcuate retaining tabs II6 that frictionally engage the tip end I I2 of the bulb l8.

Receivably engagin a suitable internally threaded aperture provided in the anchor member 50 is a pivot pin H8 that pivotally supports a locking arm I20 having a bearing end I22 and a finger engaging lug I24. Loosely embracing the pivot pin H8 and positioned in a recess I28 provided in the anchor member 50 is a coil spring I28 having oppositely disposed angulated end portions I30 and I32, one of which is fixed in the recess I26 and the opposite end of which is fixed to the locking arm I20 to normally retain the bearing end I22 of the locking arm I20 into frictional engagement with the closure plate 98 so that the retaining ring 95 will be fixed in the notch 54 between the forward vertical face of the notch 54 and the bearing end 22, and the housing I0 fixed to the anchor member 50.

In practical use of the present invention, by

adjusting the rod 38, the same will engage the base of the battery 22 to complete the circuit to the bulb I8 and light will be emitted through the lens I04 and opening I00. To de-energize the bulb I8, the rod 38 is loosened so that the rod 38 will be spaced relative to the battery 22 and the circuit to the bulb 18 will be open.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the device will be quite apparent to those skilled in this 4 art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claims.
