GUN SIGHT MOUNTING Filed Jan. 5, 1949 Fig.

I n l/entors George M. Fischer Baz/e G. Fischer EUJUE? Patented Nov. 20, 1951 cannon EWUM GUN SIGHT MOUNTING George M. Fischer and Bazle G. Fischer, Billings, Mont.

Application January 5, 1949, Serial No. 69,326

4 Claims.

This invention relates to new and useful improvements and structural refinements in mountings for gun sights, and the principal object of the invention is to facilitate convenient lateral as well as vertical adjustment of the gun sight, and to enable the use of the same sight on several guns, so as to eliminate the conventionally experienced necessity of providing an individual sight and mounting for each gun used by a hunter.

This object is achieved by the provision of the mounting herein described which is adaptable, without disturbing its adjustment, to various guns, and wherein novel means are provided for adjusting the sight both in a vertical as well as in a horizontal plane.

One of the advantages of the invention resides in the interchangeability of its components, whereby the user does not need to purchase the entire device of only a component thereof needs to be replaced.

Some of the advantages of the invention reside in its simplicity of construction, efficiency of operation, and in its adaptability to economical manufacture.

With the above more important objects and features in view and such other objects and features as may become apparent as this specification proceeds, the invention consists essentially of the contruction and arrangement of parts as shown in the accompanying drawings in which:

Figure 1 is a perspective view of the invention in situ on a gun;

Figure 2 is a perspective view of the invention per se;

Figure 3 is a longitudinal cross sectional view showing the invention applied to a gun;

Figure 4 is a cross sectional view, taken substantially in the plane of the line 4--4 in Figure 3; and

Figure 5 is a cross sectional view, taken substantially in the plane of the line 5--5 in Figure 3.

Like characters of reference are employed to designate like parts in the specification and throughout the several views.

Referring now to the accompanying drawings in detail, the invention consists of a mounting for a gun sight, the mounting per se being designated generally by the reference character I0, while the gun sight, of the usual telescopic type and of the usual, substantially tubular construction, is indicated at l 2.

The mounting l0 embodies in its construction an elongated base I4 which is attachable in a longitudinally extending position to a gun I8, preferably to the breech portion 18 of the gun stock 20, the attachment of the base [4 to the gun It being effected by means of a plurality of suitable screws 22 located in a plurality of apertures with which the base I4 is provided substantially as shown.

It is to be noted that the forward end portion of the base I4 is upturned as at 24 and is formed with a substantially V-shaped seat 26 for the forward end portion of the tubular sight l2, while the rear end portion of the base I4 is formed with screw threaded apertures so as to accommodate a pair of transversely spaced, parallel and vertically extending adjusting screws 28.

These screws are equipped with substantially conical heads 30 which provide upwardly divergent seating surfaces for the rear end portion of the sight [2, and it is to be also noted that the screws 28 are provided in the lower portions 01. the heads 30 with sets of apertures 32 to receive a pin, or the like, whereby the screws may be easily and conveniently turned.

Moreover, the rear end portion of the base [4 is equipped with a pair of set screws 34 which are engageable with the screw threaded portions or shanks of the screws 28, whereby the latter are prevented from turning when the set screws 34 are tightened.

Intermediate portions of the base l4 are reduced in cross section as indicated at 36- and again at 38, the longitudinal edges 40 of the base portion 36 being downwardly and inwardly chamfered as is best shown in Figure 5. A plate 42 is removably positioned on the base portion 36 and is provided with downwardly convergent side flanges 44 which engage the edges 40 in a frictional clamping manner, and retain the plate 42 in position. Moreover a clamping screw 46 extends through the flanges 44, thus securely attaching the plate to the base.

It is to be noted that the plate 42 is provided with a longitudinally extending depression or concavity 41 which constitutes what may be called a cradle for an intermediate portion of the tubular sight l2, and a pair of spaced parallel retaining bands 48 have their end portions secured to the plate 42 as indicated at 50. The bands 48 extend circumferentially around the intermediate portion of the sight l2 and thereby urge the forward and rear end portions of the sight in engagement with the seating surfaces 26, 30 respectively, as will be clearly apparent.

When the invention is placed in use, the mounting is assembled as shown in the drawings, the sight I2 being applied to the mounting in such manner that the straps 48 retain the intermediate, forward and rear portions of the sight in engagement with the seating surfaces 41, 26 and 30 respectively, as is best shown in Figure 1.

screws 28 is rotated so that the head thereof' urges the rear end portion of the sight to one side or the other, as the case may be. It will be apparent that in this manner the vertical as well I as horizontal adjustment of the gun sight is facilitated. e

It will be apparent from the foregoing that several of the bases l4 may be used, each mounted on a different gun and having the screws 28 thereof adjusted to suit that gun, while one sight l2, equipped with the plate 42 and bands 48, may be used selectively with the several bases without a disturbance of sight adjustment, this being facilitated by simply removing the screw 46 and separating the plate 42 from thebase for installation on a similar base on another gun, without disturbing the adjustment of the screws 28.

The bands 48 are loosened only when the plate 42 is initially attached or applied to a given gun sight, after which these bands serve to securely hold the sight in position on the plate. The flanges 44 are clamped in a new position on the base when the sight is initially mounted and adjusted for a given gun, but after that it is merely a matter of. loosening the screw 48 and removing the plate 42' from the base I4 when the sight together with the plate 42 is to be transferred from one gunto another.

It is believed that the advantages and use of the invention will be clearly understood from the foregoing disclosure and accordingly, further description thereof at this point is deemed unnecessary.

While in the foregoing there has been shown and described the preferred embodiment of this invention it is to be understood that minor changes in the details of construction, combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.

Having described the invention, what is claimed as new is:

1. In combination with a substantially tubular gun sight, a mounting comprising an elongated base attachable in a longitudinally extending position to a gun, the forward end portion of said base being upturned and formed with a V-shaped seat for the forward end portion of the sight, a pair of transversely spaced and parallel adjusting screws extending upwardly from screwthreaded apertures formed in the rear end portion of said base, said screws having substantially conical heads providing upwardly divergent seating surfaces for, the rear end portion of the sight, a plate having downturned flanges adapted to straddle longitudinal edges of an intermediate portion of said base, a clamping screw extending through said flanges whereby the latter may be urged in frictional engagement with said base, and a plurality of sight clamping bands having ends thereof secured to said plate, whereby said plate and the associated sight may be bodily removed from said base without disturbing the ad- J'ustment of said screws.

' 2. The device as defined in claim 1 wherein said longitudinal edges of the intermediate portion of said base are downwardly and inwardly chamfered, said flanges being downwardly convergent to clamp the chamfered longitudinal edges of the base.

3. The device as defined in claim 1 wherein said plate is formed with a concave cradle to receive an intermediate portion of the sight.

4. The device as defined in claim 1 together with set screws provided in said base for locking said adjusting screws.
