/ MOUN'l FOR TELESCOPIC SIGHTS Filed April 3, 1944 WILLIAM H. ENGLISH INVENTOR.
BY dTw k Patented Sept. 24, 1946 UNITED STATES PATENT OFFICE 2 Claims.
This invention relates to a mount for telescopic sights and, more particularly, to a scope mount that may be readily attached to and is readily removed from a receiver of a rifle or other firearms.
Telescope mounts f or firearms which are known in the prior art are usually large and complex, and are often so bulky that they interfere with the handling and use of a weapon. It is a common criticism that the prior art scope mounts are difficult to adjust as well as to mount or dismount.
Having in mind the defects of the prior art, it is an object of this invention to provide a mount for telescopic sights adapted for lateral and longitudinal adjustment of the telescope relative the firearm to which it is attached.
Another object of my invention is to provide, in a mount of the type described, an arrangement of parts which may be readily attached to the gun receiver of a great majority of the firearms now currently used.
A still further object of the invention is the provision, in a mount as described, of rapid-action means between relatively movable parts for securing the same.
Still another and further object of this invention is to provide, in a scope mount, a cam lock between relatively movable adjacent parts which may be readily locked as well as unlocked and will not be deleteriously affected by repeated and hard usage.
The foregoing objects and others ancillary thereto I prefer to accomplish as follows:
According to a preferred embodiment of my invention, I attach a base member fixedly upon the receiver of a firearm to one side thereof. This member stands upwardly so that an upper portion lies alongside the usual ejector opening of the receiver. Upon the upper surface of this base I form a longitudinal dovetail which extends parallel to the axis of the firearm. Mounted upon the dovetail by means of suitable ways coacting with the dovetail, is a slider member adapted for longitudinal movement relative the firearm. Between the slider and the base I mount lock means comprising a tapered head member which is mounted in the base for vertical movement. The tapered head, in the locking position, engages the ways of the slider and clamps the slider to the base. Vertical movement of the lock member is obtained by a rotatable pin having a crank thereon, which raises or lowers the locking member into clamping position. Swinging movement of the crank is provided by a lever arm ex- 2 temal of the base which ma be manually swung when and as desired. Mounted upon the slider for lateral movement with respect thereto, are clamp loops for engagement around the tube of a telescope to secure the same in proper relation to and overlying the barrel of a firearm.
The novel features that I consider characteristic of my invention are set forth with particularity in the appended claims. The invention itself, however, both as to its organization and its method of operation, together with additional objects and advantages thereof, will best be understood from the following description of a specific embodiment when read in connection with the accompanying drawing, in which:
Figure l is a side view of a portion of a firearm having my mount for telescopic sights attached thereto;
Figure 2 is an end view of the telescopic sight mount;
Figure 3 is an enlarged side view of my mount for telescopic sights with portions of the mount broken away and shown in section for convenience of illustration;
Figure 4 is a vertical sectional view taken on the line 4-4 of Figure 3; and
Figure 5 is a medial sectional view of a clamping member for a telescopic sight and is taken along the line 5-5 of Figure 3.
A mount for telescopic sights for firearms, to overcome the defects hereinbefore enumerated, must have at least two totally distinct characteristics; it must be capable of easy attachment to and adjustment with respect to a firearm; and it must provide a secure and rigid support for a telescopic sight to hold the same in a manner to prevent misalignment during normal handling of a firearm so equipped. Accordingly, a preferred embodiment of my invention, referring to Figures 1 and 3 0f the drawing is constituted by a mount base Ill that is drilled and counter-sunk at II to receive screws I2, whereby it may be attached to a receiver Id of a gun having a barrel l6 and stock l8. The mount base is an elongated member relatively thin in its lower portion for attachment to the near side face of a gun receiver.
Upon its upper face, member H] has a dovetail slide 20 which extends parallel to the longitudinal axis of the gun and receives the slider 22 that has ways 24 matching with the dovetail 20. In a suitable recess in the dovetail 2D is positioned the inverted frusto-conical clamp head 26 which has, extending into recess 21, the lower pin 28. Pin 28 and the head 26 are adapted to move in reciprocation along their common vertical axis. At right angles to the axis of the pin 28 on an axis intersecting thereto is the rotatable pin 30 which has a crank pin 32 fitted into a hole 34 that passes laterally through the pin 28 to move the same downwardly in its recess to allow head 26 to grip the slides. Pin 30 is secured in place by means of the threaded sleeve 40 that is mounted in a suitable longitudinal opening of the base Ill. The pin 30 extends exteriorly of the base HI and has a lever 42 pinned thereto to permit manual grasping and turning of the pin 30 and its crank 32.
In the upper face of the slider 22 I form lateral ways 44 in which the lateral dovetail 46 of the scope loop 48 is mounted to permit lateral adjustment of a telescopic sight tube 50 relative the gun barrel. The loop 48 is divided at 52 and screw 54, between the parts on each side of the dividing line, serves to draw the parts together in order to clamp the loop about a telescope tube.
While I have shown and described particular embodiments of my invention, it Will occur to those skilled in the art that various changes and modifications may be made without departing from the invention, and I, therefore, aim in the appended claims to cover all such changes and modifications as fall within the true spirit and scope of my invention.
Having thus described my invention, I claim:
1. In a mount for telescopic sights, comprising: a base plate adapted to be secured to firearm, a dovetail rib on said base plate, a slider having a groove shaped to fit said dovetail rib and mounted thereon, means on said slider for securing a telescopic sight tube thereto,a section of said dovetail being depressible, crank means for depressing said depressible section, and means in said base plate extending through an end edge thereof for operating said crank means to depress said section whereby the slider is locked to the base plate,
2. In a mount for telescopic sights, a base plate adapted to be secured to a firearm, a dovetail rib on said base plate, a slider having a groov shaped to fit said dovetail rib and mounted thereon, means on said slider for securing a telescopic sight tube thereto, a pin vertically movable in said base plate and having an inverted frustoconical head dovetail, a shaft mounted in said base plate longitudinally thereof at right angles to said pin, means externally of the base plate for rotating said shaft, and a crank between said shaft and said pin whereby the latter may be reciprocated in its vertical path.
WILLIAM H. ENGLISH.
