No. 685,512 lnt. Cl. F41g 1/38 lU.S. Cl. 2482tl5 1 Claim ABSE'll 01F THE DISCLOSURE A mounting system for a rifle telescopic sight comprises a pair of cradle type mounts in combination with a pair of upper clamps and a lower mounting plate. The cradle mounts are sufiiciently high to raise the telescopic sight above the line of vision through the fixed rifle sights, and are provided with a large longitudinal aperture to permit sighting directly through these cradle mounts when it is desired to use the fixed sights rather than the telescopic sight.

Summary of invention A rifle telescopic mounting system comprising a single plate secured to the top of the barrel and bridging the firing chamber opening, being locally narrowed to prevent interference with such opening. Two identical scope-supporting cradles are removably connected to the plate, and are provided with large openings to permit normal use of the rifle fixed sights without removal of the telescopic sight.

Description of the drawings Structure and operation Referring now to the drawings, there is illustrated in FIG. 1 a conventional bolt action rifle 10 having a telescopic sight 12 secured to the rear or receiver portion of barrel 14.

As best seen in FIGS. 1 and 2, the mounting means for telescopic sight 12 comprises a base plate 16 which is secured at both ends to the rifle receiver 14 by screws 18. Base plate 16 has a cut-off or notched portion so that it will not obstruct the firing chamber when the bolt 20 of the rifle is open for loading or ejection.

A pair of identical cradle type mounts 22 is bolted to base plate 16. For this purpose, each mount 22 is provided with an integral downwardly directed stud 24 which passes through a clearance hole in base plate 16 and engages a large diameter but thin disk-like nut 26. As can be seen in FIGS. 1 through 3, nut 26 is received in a transverse slot in the under side of base plate 16 and projects outwardly from each side of the base so that it may be gripped for loosening or tightening.

The mounting means further comprises a pair of upper clamps 28 secured by screws 30 to each of cradle mounts 22. It is contemplated that once the scope is secured to mounts 22 by clamps 28, this sub-assembly could be permanent if desired. Thus, the scope would be normally States Patent See removed from the rifle by disengaging the two nuts 26 from studs 24, while leaving the base plate 16 on the rifle,

Prior art telescopic sight mounting means have had the undesirable characteristic of obscuring the users view of the fixed sights of the rifle. The fixed sights were obscured by both the telescopic sight itself and the mounting means. This is undesirable, since a situation might occur where a target presented itself at a close range not necessitating the use of the telescopic sight. Furthermore, some hunters prefer to use the fixed sights for rough preliminary sighting prior to switching to the telescopic sight for final zeroing in on the target. Conventional rear and front fixed sights are illustrated at 32 and 33, respectively, in FIGS. 1 and 3.

By means of the improved mounting system of this invention, the cradle portion 22 of the mount is made higher than usual, to elevate the telescopic sight 12 above and out of the line of sight through the fixed rifle sight. Furthermore, the cradle mount 22 is provided with a large longitudinal aperture 34, which permits the user of the rifle to sight through the cradle itself and through the fixed sights of the rifle, when he desires to use the fixed sights. Thus, he may either use the telescopic sights or the conventional sights without the necessity of first removing the telescopic sight and mounts.

Thus, the improved mounting system of this invention gives a clear unobstructed view of the fixed sights, and is large enough to permit an ample field of vision. Not only does this system permit the fixed sights to be used independently of the telescopic sight, but it also permits normal tracking of a moving target by the preliminary use of the fixed sights prior to the final delicate sighting through the telescopic sight. FIG. 3 illustrates the view of the

fixed sights

32, 33 which one woud have sighting through the aperture 34 in the cradle mount 22. It will be noted that telescopic sight 12 does not in any way obscure these sights.

A modification of the mounting means is illustrated in FIG. 4. Here, the base plate is in the form of a track 36 upon which the cradle mount 38 may be longitudinally adjusted. A notch 40 near the bottom of one side of the mount receives a channel shaped clamp 42 which may be tightened in place by thumb screw 44 to securely lock the mount to the track. An upper notch 46 receives one end of upper clamp 48, while other end of the clamp is provided with a flange 50 which may be secured to the opposite side of the cradle mount by screws 52. As in the case of the embodiment of FIGS. 1 through 3, the cradle mount is provided with a large viewing aperture 54 and is sufficiently high to prevent obstruction of the fixed sights.

What is claimed is:

1. Mounting means for removably mounting a telescopic sight upon a rifle barrel having an upper, elongated firing chamber opening and fixed sights mounted upon the rifle barrel, comprising:

a single, thin, flat, horizontal base plate having its opposite ends secured to the barrel rearwardly and forwardly of the firing chamber opening, with the plate extending longitudinally over and bridging said opening, and with the central portion of the plate being narrowed along the length of the opening for sidewise and upwards clearance of the opening, and with the upper surface of the plate being below the plane of said fixed sights;

a transverse channel formed in the lower face of the plate adjacent each of its opposite ends and containing a flat, disc shaped nut having a centrally threaded opening and being of a diameter greater than the width of said plate so as to extend beyond the side edges of said plate for manual rotation and a vertical hole formed through the plate in alignment with each of the nut threaded openings;

a pair of identical cradle mounts, each having a downwardly depending threaded stud extending through one of said plate holes and threadedly engaged with the nut aligned with the respective holes;

each cradle mount extending upwardly a considerable distance above the base plate and having upper clamping means receiving and securing a telescopic sight;

each cradle mount further having a single large unobstructed aperture extending completely therethrough below its clamping means, the apertures being centrally aligned with the fixed sights of the rifle for providing an unobstructed line of sight along the fixed sights, with the telescopic sight line thereby being above the fixed line of sight;

whereby either the fixed sight or the telescopic sight may be alternatively used without removal of the telescopic sight, and whereby the cradle mounts and the telescopic sights may be rapidly and easily removed or applied as a single unit from said base plate by manual rotation of said disc nuts.
