UNITED STATES RUDOLF NOSKE, OF SAN FRANCISCO, CALIFORNIA.

TELESCOPE-SIGHT MOUNTING.

Application filed November 3, 1921.

To all whom it may concern:

Be it known that I, RUDoLr NOSKE, a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented a new and useful Improvement in a Telescope- Sight Mounting, of which the following is a specification.

My invention relates to improvements in mountings for telescope sights for rifles and the like.

The primary object of my invention is to provide an improved mounting for telescope sights for rifles.

Another object is to provide improved locking means adapted to hold a telescope rigidly in operative position while the rifle is in use.

Another object is to provide an improved locking means adapted to facilitate the placing and removing of a telescope sight upon a rifle.

A. further object is to provide an improved mounting means for preventing transverse or lateral movement of the sight when the rifle is fired.

Another object is to provide an improved mounting having means adapted to facilitate the adjusting of a telescope sight laterally to compensate for windage. r

A furtliei object is to provide an improved locking means adapted to compensate for wear to insure against loosening of the sight.

A still further object is to provide im proved means for limitin the movement of the locking pin to facilitate removal of the movable mounting when the sight is to be removed from the rifle, and to prevent loss of parts.

I accomplish these and other objects by means of the device disclosed in the drawings forming a part of the present specification wherein like characters of reference are used to designate similar parts throughout said specification and drawings, and in which- Fig. 1 is a broken plan view of a rifle equipped with a telescope sight secured by my improved mounting.

Fig. 2 is a broken side elevation of Fig.

Fig. 3 is a side elevation of my improved mounting shown upon a larger scale.

Fig. 4 is a plan view of Fig. 3.

Fig. 5 is a rear elevation of the mountmg.

Serial No. 513,386.

Fig. 6 is a transverse section taken on line 6-6 of Fig. 3 in the direction indicated.

Referring to the drawings the numeral 1 is used in general to designate a stationary mounting plate arranged to be screwed or otherwise secured upon the breech 2 of a rifle 3. A dovetail 4 is formed upon the upper edge of the plate 1 and a tapered groove 6 is formed upon the surface of the dovetail.

A movable plate 7 is provided with a dovetail slot 8 in the bottom surface thereof to slidably engage the dovetail 4 of the stationary plate 1 and a telescope receiving member 9 is pivotally mounted upon the movable plate 7 by means of a screw 11 or other suitable pivot, the free end of the member 9 abutting against an upwardly extending lug 12 upon the plate 7, the proximate surfaces of the lug 12 and the member 9 being made arcuate in shape to permit pivotal movement of the member 9 about the pivot 11, said lug operating to relieve the pivot from stress due to inertia of the telescope and the mounting when the rifle is fired.

A pair of telescope supporting elements 13 are formed integral with the member 9, said elements 13 being arranged in spaced relation to form a firm supporting base for a telescope sight 14;. A pair of clamping elements 16 adapted to fit over the telescope when supported on the elements 13 are apertured at the ends to receive screws 17 adapted to be screwed into the elements whereby said telescope may be firmly clamped in position upon the member 9 and hence upon the movable plate 7.

A pair of adjusting screws 18 are threaded into the lug 12 and arranged to bear upon a shoulder 19 formed upon the free end of the member 9 from opposite sides thereof whereby said member 9 may be secured in fixed lateral position with respect to the lug 12 and the member 9. The member 9 may be adjusted laterally to compensate for windage and the like, by loosening the screw 18 upon one side of the lug 12, and tightening the other screw a corresponding amount so as to engage the shoulder 19 and hold the same in rigid position in the corrected position. It is obvious that correction may be made toward either side of the mounting as the requirement may be. A plurality of calibrations 21 are preferably made upon one of the screws 18 whereby the amount of correction may be gaged, said calibrations being graduated to give a definite correction at a defined distance, any fixed point upon the mounting serving as an index from which the amount of r0ta tion may be gaged.

The shoulder 19 is fitted into a corresponding groove 22 in the lug 12 thereby serving the additional purpose of preventing vert1- cal movement of the free end of the member 9.

One of the principal difiiculties to be met in mounting a telescope sight upon a rifle is to provide a rigid locking means for preventing movement of the telescope and mounting due to inertia when the rifle is fired, the stresses caused in this way being so great as to shear and batter the ordinary securing means within a comparatively short time to such an extent as to render the mounting and sight useless. As previously stated one of my chief objects is to provide an improved locking means which is adapted to withstand such stresses and hold the sight and movable mounting plate in rigid position when mounted for use. I accomplish this in the following improved manner:

An extension 25 is formed integrally with or secured upon one side of the movable plate 7 and a centrally disposed bore 26 formed therein, said bore extending through the plate 7 and intersecting the dovetail slot 8 and forming a groove 27 thereacross, said bore 26 being positioned so that the groove 27 will match with the tapered groove 6 in the dovetail 4.

A locking pin 28 is slidably mounted within the bore 26, the forward end 29 of the pin being beveled at the inclination of the tapered groove 6. A reduced portion 31 is formed at the other end of the pin 28 to form a shoulder 32, and a notch 33 is formed in one side of the pin 28.

A nut 34 is threaded onto the extension 26, an internal annular shoulder 36 being provided at one end of said nut to engage the shoulder 32 of the pin 28 and to permit passage of the reduced portion 31 therethrough. The end of the reduced portion 32 is apertured to receive a cotter pin 35 adapted to normally hold the shoulder 36 of the nut in engagement with the shoulder 32 of the pin.

A transverse slot 37 is formed upon the extension 26 near the outer end thereof to receive a transversely disposed key 38 preferably made semicircular in shape and adapted to be inserted through the slot 37 into engagement with the notch 33 formed upon the side of the pin 28. The semicircular side of the key 38 matches with the bottom of one of the threads of the extension 26 and the flat side of the key rests upon the bottom of the notch, said notch being made of sufficient length to permit the desired amount of movement of the pin 28.

My improved locking means is assembled by inserting the pin 28 into the bore 26 with the notch 33 adjacent the slot 37. The key 38 is then inserted and the nut 34 applied thereover, said nut being advanced upon the extension 25 until the shoulders 36 and 32 are brought into engagement and the cotter pin 35 is inserted to hold said collars in engaging relation. The operation of the locking means is as follows:

The movable plate 7 being positioned upon the stationary plate 1 so that the grooves 6 and 27 will be in matching relation, the nut 34 is advanced along the extension 25, the shoulder 36 thereby moving the pin 28 into the recess formed by said grooves. A continued advance of the nut will cause the beveled end of the pin 28 to be moved in binding relation with the tapered groove 6, the pin, operating as a wedge, is rigidly bound between the movable and stationary plates. The pin also tends to lift the movable plate so that the dovetail 4 will be in binding relation with the movable plate, along the entire length of the dovetail slot 8, in this manner increasing resistance to displacement and relieving the pin 28 of the greater part of the shearing stress to which it would be otherwise subjected.

When it is desired to remove the movable mounting to dismount the sight the nut 34 is loosened, the cotter pin 35 causing the locking pin 28 to be receded to disengage and release the mounting plates, as shown in dotted lines in Fig. 6 of the drawings. The key 38 engages the forward end of the notch 33 before the nut is entirely removed from the extension 25 thereby preventing further movement of the nut or the pin 28 and insuring against loss of any part while the sight is dismounted.

My improved locking means will remain effective even after long usage as any wear that occurs will be upon the beveled end of the pin 28, and by virtue of the tapered groove 6 and the beveled end 29 such wear will be readily taken up and compensated for by advancing the pin a correspondingly greater distance into the recess between the grooves 6 and 27.

A screw 41 is placed at the rearward end of the movable plate 7 to engage the end of the fixed plate 1 to facilitate the aligning of the ends of said slates in which position the grooves 6 and 2 are preferably caused to be in matching position.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:
