MOUNT FOR TELESCOPE SIGHT Filed Dec. 27, 1966 INVENTOR CARL. E A/ELSQA/ United States Patent 3,414,221 MOUNT FOR TELESCOPE SIGHT Carl E. Nelson, Kellettville, Pa. 16330 Filed Dec. 27, 1966, Ser. No. 604,827 Claims. (Cl. 248205) ABSTRACT OF THE DISCLOSURE The telescope mount disclosed herein is made up of a base bar with a lateral groove. A saddle with two spaced telescope receiving parts in supported on the base. The base bar has slots in it which engage the points of screws on the saddle. A cam is provided on the saddle to move the saddle forward and rearward. Thus, as the saddle moves forward and rearward, the front of the saddle will move up and the rear of the saddle will move down and vice versa to adjust the elevation of the telescope relative to the rifle on which it is mounted.
This invention relates to mounting structures for adjustably and detachably mounting any telescopic sight on a firearm and, more particularly, to a mount by means of which the telescopic sight and parts of the mount embracing said sight may be readily moved to adjusted position to adjust them for elevation and windage.
It is an object of the invention to provide a mount for any telescopic sight including means for adjusting the mount and the sight car-r ied thereby relative to the firearm to provide corrections and adjustments for windage and elevation by a simple, effective means.
Another object is to provide a telescope mounting with provision for readily removing the telescope.
With the above and other objects in view, the present invention consists of the combination and arrangements of parts hereinafter more fully described, illustrated in the accompanying drawing and more particularly pointed out in the appended claims, it being understood that changes may be made in the form, size, proportions, and minor details of construction without departing from the spirit or sacrificing any of the advantaged of the invention.
In the drawings:
FIG. 1 is an isometric view of the mounting structure according to the invention,
FIG. 2 is an exploded view of the parts of the sight.
Now with more particular reference to the drawings, the telescopic sight mount has a base bar 11 and a saddle support 12 supported thereon. The saddle support 12 has the saddles 13 and 14 rigidly connected to them. The saddles 13 and 14 have a U-shaped portion with the connecting member 30 forming one leg of the U and the legs 31 forming the other leg of the U. The legs formed by 30 and 31 have parallel inside surfaces which are supported along the sides of the ends of the base bar 11. A cam has an axle 32 offset from the axial center of cam 15. Cam 15 is received in a hole 33 in the connecting member 30 and a screw head 34 is attached to the axle 32 by which the cam 15 may be rotated. Seat screws 16, 17, 18, and 19 are received in respective threaded holes 40, 41, 42, and 43. Screwdriver slots in these screws may be used as an indicator to point to the calibration marks around the holes 40, 41, 42, and 43.
The points 44 of the screws are received in the follower slots 45 and 46' in the sides of the base bar.
The base bar has laterally extending lugs 37 which may be considered a first portion of the base bar which define a slot that receives the cam 15.
The base bar 11 has the end members 45 and 46 that have holes 47 therein which may receive screws for attaching the base bar to the receiver of a rifie indicated generally at 50.
3,414,221 Patented Dec. 3, 1968 The overlying half-rings 23 and 24 are held in place by means of screws 20, 21, 22, and 25 which are received in threaded holes 48. The telescope to be used can be supported in the saddles 13 and 14 with the overlying halfrings 23and 24 supported on top of it holding it in place in the saddle. Thus, when the end members 45 and 46, which may be considered to be a second portion and a third portion, are attached to the receiver of a firearm and the cam 15 which is a first cam means received in a second cam means which is the space between the lugs 37 and the points 44 of the screws 16, 17, 18, and 19 on fourth cam means received in the follower slots 45 and 46" and tightened the sight will be held rigidly in place. To adjust the sight for elevation the cam 15 is rotated by rotating the screw head 34. This will cause the points 44 at the front of the base bar to move up or down the follower slots 45 which are a third cam means and points on the screws 17 and 18 to move either up or down in the slots 46' depending on the direction of rotation of the screw. The sight can be adjusted for windage by adjusting the screws 17 and 18 or the screws 16 and 19. Screwholes 49 are provided for mounting a telescope cover such as shown in Patent No. 3,208,146.
The foregoing specification sets for the invention in its preferred practical forms but the structure shown is capable of modification within a range of equivalents without departing from the invention which is to be understood is broadly novel as .is commensurate with the appended claims.
The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:
1. A telescope mounting comprising a base bar,
means for attaching said base bar to a gun,
said base bar having a laterally disposed groove therein,
said saddle having means thereon for attaching it to a telescope,
a first cam means rotatably supported on said saddle,
second cam means on said base bar engaging said first cam means,
third cam means on said base bar in front of said second cam means and spaced therefrom,
fourth cam means on said saddle spaced forward of said first cam engaging means and engaging said third cam means,
said first cam means moving said saddle and said fourth cam means relative to said third cam means, thereby moving said saddle downward and forward or moving said saddle downward rearward of said base bar whereby said telescope supported on said saddle is adjusted in elevation.
2. The telescope mounting recited in claim 1 wherein said third cam means comprises a slot and said fourth cam means comprises a screw.
3. The telescope mounting recited in claim 1 wherein said third cam means comprises slots in said base bar extending forwardly and downwardly.
4. The telescope mounting recited in claim 3 wherein said second cam means comprises a slot in said base bar.
