Cl. 33-50 3 Claims ABSTRACT OF THE DISCLOSURE A substantially C-shaped elongated mounting assembly is disclosed for fastening a telescopic sight to a gun. The assembly has a partially enclosed aperture which serves in sighting along metallic or barrel sights.

CROSS REFERENCE TO RELATED APPLICATIONS This is a continuation-in-part of my copending application, Serial No. 803,713, now abandoned, filed Mar. 3, 1969.

BACKGROUND OF THE INVENTION This invention relates to mounting apparatus for securing a sighting device, such as a telescopic sight to a gun. More particularly, it pertains to mounting apparatus secured to the top surface of a gun receiver assembly and including an aperture for improved metallic or barrel sighting.

Rifles and similar firearms are ordinarily furnished with metallic sights which comprise a front and rear upstanding members mounted on the top surface of a gun barrel. The tops of the members are aligned for directing a fired bullet to its target. Metallic sights are used principally for short distances while, for longer distances, a telescopic sight, mounted on top of the gun, is used. In hunting, barrel as well as scope sights must be equally convenient and available to the rifleman.

Accordingly, it is an object of this invention to secure a telescopic sight to the top of a gun barrel without the necessity for obscuring or hindering the use of barrel top sights.

It is another object to furnish a scope mount which also functions as a third barrel sighting member useable with conventional metallic sights.

Yet another object is to provide a unitary mounting assembly having a continuous curved interior surface member adapted to reflect ambient light along a sighting axis.

A further object is to reduce the cost and complexity of mounts for telescopic sights.

SUMMARY OF THE INVENTION The foregoing and other objects are attained in accordance with a specific illustrative embodiment of the invention comprising an elongated C-shaped member having a bottom curved surface for interfitting with the top surface of a gun receiver assembly. A top surface of the member is shaped to accommodate the telescopic sight and its mounting apparatus.

Importantly, the interior surface of the member, also having substantially a C-shape, outlines the rear and front metallic sights as viewed from the conventional sighting angle, i.e. from the rear of the rifle. When the tops of the barrel top sighting members are aligned, they appear at the center of the outline formed by the grooved interior surface, thus, enabling the user facilely and with enhanced accuracy to utilize existing sighting means.

A unique advantage of the mount assembly is the fact the side opening of the mount enables ofl-target game to be continuously and simultaneously viewed until the barrel sights are aligned on the game. Moreover, the interior surface of the mount is curved and light reflective. Principally because of the curvature of the interior surface, reflected light is focused and concentrated so that ambient light bathes the viewing axis. Therefore, there is no substantial change in lighting conditions whether a quarry is viewed in sight alignment or outside the mounting assembly.

A manifest advantage of this mount is that it enables the rifleman to rapidly verify the accuracy of the telescope without the necessity for sighting through the barrel. In prior arrangements in which the mounting of a scope sight obscured the barrel sights, it was necessary to partially disassemble the weapon in order that a sighting could be made through the barrel for checking the accuracy of the scope. With my invention, the scope sight adjustment may be verified and corrected simply by comparison with a metallic sighting since my mount does not obscure the barrel sights.

In an alternative embodiment of my invention a portion of the bottom surface of the mount is removed and another portion of that surface has a greater thickness to accommodate those rifles which load shells from the top of the receiver assembly. Advantageously, the features and objects described above are contained in this particular embodiment as will be hereinafter described.

DESCRIPTION OF THE DRAWING The foregoing and other objects, features and advantages of this invention will be more clearly understood from a reading of the following description with reference to the drawing in which:

FIG. 1 sets forth a side view of a rifle 21 together with a telescopic sight 20 secured by scope mount 1 to a receiver assembly 25,

FIG. 2 is a perspective view of scope mount 1;

FIG. 3 is an end sighting view through mount 1 showing the positioning of front barrel sight 23 and rear sight 22 when properly aligned; and

FIG. 4 depicts an alternative embodiment of mount 1 for top loading rifles DETAILED DESCRIPTION Referring to FIG. 1, it shows the positioning of mount 1 on rifle 21. As may be seen barrel

sights comprising members

22 and 23 are viewed through mount 1. To utilize the scope 20, the rifleman elevates his eye as shown in the figure.

Considering mount 1 in greater detail and with reference to FIG. 2, it is an elongated and a substantially C-shaped assembly. Barrel interfitting surface 5 is curved over the length of the assembly. The curvature of surface 5 conforms to that of receiver assembly 25 (FIG. 1). The interior surface 2 is also substantially C-shaped and has a grooved interior running the length of mount 1.

Mounting holes 1013 are counter-sunk to provide for flush mounted screws (not shown) which secure mount 1 to receive assembly 25.

Positioning of holes 1013 is determined by the position of threaded holes in assembly 25 which threaded holes are ordinarily furnished by the rifle manufacturer to accommodate scope mounting. Thus, yet another important advantage of the invention is that it does not require additional drilling in the gun barrel for fastening mount 1 to assembly 25. Access holes 14-17 are aligned vertically with respective holes 10-13 and have sufficient diameter to allow insertion of a tool through holes 14-17 to tighten or loosen-the mounting screws in holes 1013. Advantageously, since the side of mount 1 is open for its entire length, positioning of mounting screws in holes 1013 may be done facilely by hand.

Bevel faces 6 and 7 are shaped to receive a convention mounting band looped around the telescopic sights situated on top surface 3.

Guide groves 8 and 9 receive downward extending members (not shown) of the telescopic sight. When those members are properly seated they prevent forward or rearward motion of a properly fastened scope sight.

It is to be noted that the overall shape of mount 1 is such that it, advantageously, may be machined or made by an extrusion process. Thus, the cost of producing this mounting is appreciably less than others in the prior art.

Attention is next directed to FIG. 3 which depicts an end view of mount 1 and the barrel top sights as seen by a rifleman. When the rifle is properly aligned on target,

(a) member 23 appear as shown above member 22,

(b) member 23 is situated substantially at the center of the outline formed by the C-shaped interior of mount 1, and

(c) the apparent thickness a of the interior surface 2 shown by dot-dash lines is uniform.

Accordingly, any or all of the foregoing may be depended on for sighting the rifle.

To further enhance the sighting capability of mount 1, rifling lines or grooves running the length of interior surface 2 can be provided. In addition, surface 2 can be polished to enhance the light reflective qualities of that surface. In practice, the mount was treated With a blueing compound in the customary manner. Due to the curvature of surface 2, however there was an appreciable increase in the ambient light intensity along the sighting axis even though the surface light reflective qualities are diminished by blueing.

FIG. 4 shows a side view of an alternative arrangement of mount 1 in which a portion of the bottom mount surface indicated by dimension x is removed. In this manner the mount can accommodate top loading rifles. Oftentimes, the top receiver assembly surfaces of a top loading rifle are not in the same plane. To insure the proper positioning of scope 20 on rifle 21, as indicated by dimension y a portion of the bottom mount surface has an in creased thickness. This raises the front end of mount 1 and aligns the scope.

It is to be understood that the herein before described arrangements are illustrative of the application of the principles of this invention. For example, the mount can be used on hand guns and on weapons capable of firing large diameter shells. In light of this teaching, it is apparent that numerous other arrangements may be devised by those skilled in the art without departing from the spirit and scope of the invention.
