BY ‘ dTwdk mi 6. it 2,407,977 Patented Sept. 24, 1946 UNITED STATES PATENT OFFICE 2,407,977 MOUNT FOR TELESCOPIC SIGHTS William H. English, Seattle, Wash. Application April 3, 1944, Serial No. 529,306 2 Claims. (Cl. 33-50) 1 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 ri?e or other ?re arms. 2 temal of the base which may 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 and are often so bulky that they interfere with to and overlying the barrel of a ?rearm. The novel features that I consider character istic of my invention are set forth with particu the receiver of a ?rearm to one side thereof. This to prevent misalignment during normal handling Telescope mounts f or ?rearms which are known in the prior art are usually large and complex, larity in the appended claims. The invention the handling and use of a weapon. It is a com mon criticism that the prior art ’scope mounts 10 itself, however, both as to its organization and its method of operation, together with additional are dif?cult to adjust as well as to mount or dis objects and advantages thereof, will best, be un mount. derstood from the following description of a Having in mind the defects of the prior art, speci?c embodiment when read in connection with it is an object of this invention to provide a mount for telescopic sights adapted for lateral 15 the accompanying drawing, in which: Figure l is a side view of a portion of a ?rearm and longitudinal adjustment of the telescope rela having my mount for telescopic sights attached tive the ?rearm to which it is attached. thereto; Another object of my invention is to provide, Figure 2 is an end view of the telescopic sight‘ in a mount of the type described, an arrangement mount; of parts which may be readily attached to the gun Figure 3 is an enlarged side view of my mount receiver of a great majority of the ?rearms now for telescopic sights with portions of the mount currently used. ‘ broken away and shown in section for con A still further object of the invention is the venience of illustration; ' provision, in a mount as described, of rapid-action Figure 4 is a vertical sectional view taken on means between relatively movable parts for se 25 the line 4-4 of Figure 3; and curing the same.

Accordingly, a pre I form a longitudinal dovetail which extends parallel to the axis of the ?rearm. Mounted upon the dovetail by means of suitable ways co acting with the dovetail, is a slider member 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 ?rearm. Between the slider and the base I mount lock means comprising a tapered head member which is mounted in the base for vertical move attachment to the near side face of a gun re ferred embodiment of my invention, referring to tion lies ‘alongside the usual ejector opening of the receiver. Upon the upper surface of this base 40 Figures 1 and 3 0f the drawing is constituted by adapted for longitudinal movement relative the 45 member relatively thin in its lower portion for ceiver. Upon its upper face, member H] has a dove tail slide 20 which extends parallel to the longi ment. The tapered head, in the locking position, engages the ways of the slider and clamps the 50 tudinal axis of the gun and receives the slider 22 that has ways 24 matching with the dovetail 20. slider to the base. Vertical movement of the lock In a suitable recess in the dovetail 2D is positioned member is obtained by a rotatable pin having a the inverted frusto-conical clamp head 26 which crank thereon, which raises or lowers the locking has, extending into recess 21, the lower pin 28. member into clamping position. Swinging move ment of the crank is provided by a lever arm ex 55 Pin 28 and the head 26 are adapted to move in 2,407,977 3 4 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 Having thus described my invention, I claim: 1. In a mount for telescopic sights, compris ing: a base plate adapted to be secured to ?rearm, which has a crank pin 32 ?tted into a hole 34 a dovetail rib on said base plate, a slider having that passes laterally through the pin 28 to move 5 a groove shaped to fit said dovetail rib and the same downwardly in its recess to allow head mounted thereon, means on said slider for secur 26 to grip the slides. Pin 30 is secured in place ing a telescopic sight tube thereto,‘a section of by means of the threaded sleeve 40 that is mount said dovetail being depressible, crank means for ed in a suitable longitudinal opening of the base depressing said depressible section, and means Ill. The pin 30 extends exteriorly of the base HIV in said base plate extending through an end edge and has a lever 42 pinned thereto to permit man thereof for operating said crank means to de ual grasping and turning of the pin 30 and its press said section whereby the slider is locked to crank 32. . the base plate, In the upper face of the slider 22 I form lateral ‘ 2. In a mount for telescopic sights, a base plate ways 44 in which the lateral dovetail 46 of the 15 adapted to be secured to a ?rearm, a dovetail scope loop 48 is mounted to permit lateral ad rib on said base plate, a slider having a groove justment of a telescopic sight tube 50 relative shaped to ?t said dovetail rib and mounted there the gun barrel. The loop 48 is divided at 52 and on, means on said slider for securing a telescopic screw 54, between the parts on each side of the sight tube thereto, a pin vertically movable in dividing line, serves to draw the parts together 20 said base plate and having an inverted frusto in order to clamp the loop about a telescope tube. conical head dovetail, a shaft mounted in said While I have shown and described particular base plate longitudinally thereof at right angles embodiments of my invention, it Will occur to to said pin, means externally of the base plate those skilled in the art that various changes and for rotating said shaft, and a crank between said modi?cations may be made without departing 25 shaft and said pin whereby the latter may be from the invention, and I, therefore, aim in the reciprocated in its vertical path. appended claims to cover all such changes and modi?cations as fall within the true spirit and WILLIAM H.
