ATTORND I 2,855,68 I lCC Patented Oct. 14, 1953 AUXILIARY SIGHTING DEVICE FOR SHOT GUNS AND OTHER ARMS Orval M. Christensen, Decatur, Ill.

Application April 16, 1957, Serial No. 653,207 2 Claims. (CI. 33-47) This invention relates to an auxiliary sighting device for shot guns and other arms.

It is well known by those having had experience in the use of arms, and particularly shot guns, that in the act of sighting a target, an unlimited range of vision is before him as well as to each side of the gun sight.

Such unlimited range of vision makes it difficult to quickly and accurately sight a target since the eye which must be concentrated on the sight sees also objects at distances from either side of the sight, and furt hermore, the unguarded sight does not stand out sufiiciently clearly to enable quick and accurate sighting of the target.

It is accordingly a primary object of this invention to provide a device which is quickly applicable to a gun barrel and which acts to confine the sight and limit the range of vision.

A further object of the invention is the provision of a device of the above noted general character which is simple in construction, durable in use, and efiicient in operation.

Other objects and advantages of the invention will become apparent in the course of the following detailed description, taken in connection with the accompanying drawing, wherein- Fig. l is a side elevational view of the muzzle end of a single barrel shot gun with the improved device operatively mounted thereon and shown in longitudinal vertical section.

Fig. 2 is a front end elevational view of the structure shown in Fig. 1.

Fig. 3 is a vertical sectional view as observed in the plane of line 3-3 on Fig. 1.

Fig. 4 is a top plan view of the structure of Fig. 1.

Fig. 5 is a perspective view of the improved device.

Fig. 6 is an enlarged fragmental front end view of the device.

Fig. 7 is a broken side elevational view of a modified form of device as mounted on the muzzle end of a double barreled shot gun.

Fig. 8 is a front elevational view of the structure of Fig. 7.

Fig. 9 is a vertical sectional view as observed in the plane of line 9--9 on Fig. 7.

Fig. 10 is a top plan view of the structure of Fig. 7.

Fig. 11 is a perspective view of the modified form of device.

Fig. 12 is an enlarged fragmental front endview of the modified form of device.

Referring now in detail to the drawing, and first to Figs. 1 to 6 thereof, the improved device in accordance with a first embodiment thereof is designated in its entirety as 10 and' which structurally embodies a pair of wings 11 whose fore and aft ends are connected by unitary circular bands 12 which are adapted to engage the forward end portion of a single barrel B of a shot gun having a sight S adjacent its muzzle end.

As is indicated, the inner edges 13 of the wings are in laterally spaced parallel relation and the connecting bands 12 are not completely circular but extend from one edge 13 to the other for a purpose later to appear.

The device is of relatively light gauge sheet material and preferably constructed of plastic in various colors to suit the fancy of a user. The inner walls of the bands 12 are preferably provided with a rubber coating 14 which frictionally retains the device on the barrel B and restrains same against longitudinal shifting thereof as may be otherwise occasioned by kick of the gun upon firing thereof.

It is to be particularly observed that the wings 11 are of relatively small height at the rear ends thereof and the upper edges 13 of the wings are inclined upwardly from the rear ends to relatively high front ends.

Furthermore, the wings diverge upwardly fromtheir lower edges 13 to their upper edges 13 and the angular relation of the wings is different at the front and rear ends thereof.

As indicated in Figs. 2 and 3, the angular relation of the wings at their rear ends is preferably while their angular relation at the front ends is 76 and the wings are accordingly slightly transversely twisted between their front and rear ends.

The device of the second embodiment is designated in its entirety as 10 and same embodies wings 11 corresponding to those of the first embodiment. Since, however, the device 10 is adapted for use with a double barreled shot gun having a sight S disposed between the two barrels B, B, the wings 11 are spaced laterally at a greater distance than are the wings 11 in the first embodiment and the gun barrel engaging bands 12 are wider as is clearly shown in Figs. 8, 9 and 11.

In this embodiment the inner faces of the bands 12- are preferably rubber coated as in the first embodiment and for the same purpose. Also in this embodiment the front and rear angular range of the wings 11 is as in the first embodiment.

It has been observed from use of the hereindisclosed device that the resulting optical illusion is that of making the gun barrel appear approximately 8" to 10" shorter with consequent easier and faster line-up with the target, whether moving or stationary.

It has also been observed that the device when within 25 yards of the target gives a V-shape area of approximately 6 feet horizontally and 6 feet vertically whereby maximum concentration on the sight is effected.

The device, according to either embodiment thereof, is capable of being mounted or detached quickly and easily and the rubber coating on the gun barrel embracing bands functions to retain the devices in operative position.

Since one's vision in sighting a gun begins at the narrow rear ends of the wings, it has been found of advantage to form such ends at a wider angle than the forward ends which are approximately 90 and 76 respectively as above stated.

Having set forth my invention in accordance with certain specific structural embodiments thereof, what I claim and desire to secure by U. S. Letters Patent is;

1. Anlauxiliany sightingd'evice for use on the forward end of a gun. barrel and at opposite sides. oi the sight.
