UNITED STATES PATENT OFFICE GUN SIGHT Alfred M. Pasquarella, near New Bedford, Pa.

Application October 5, 1950, Serial No. 188,525

1 Claim. 1

This invention relates to a gun sight and more particularly to a gun sight for application to a service revolver to enable the same to be used as a, target pistol.

The principal .object of the invention is the provision of a simple, easily attached and adjusted gun sight for a service revolver.

A further object of the invention is the provision of a gun sight for a revolver which may be attached to the revolver without machining away a portion of the frame or other part of the revolver.

A still further object of the invention is the provision of a gun sight that provides vertical and horizontal adjustment to enable the equipped gun to be readily zeroed in on a target.

The gun sight disclosed herein provides a simple and efiicient means for converting a revolver for use as a target pistol and without the heretofore believed necessary machining away of portions of the frame of the gun and the installation of complicated gun sight mechanism in the machined portions.

As known in the art, the rear sights on revolvers are machined in the upper longitudinal portion of the frame near the hammer of the gun and are so formed as to be effective only at a relatively close range.

In order to use the gun for target shooting practice it has heretofore been necessary to machine away a portion of the frame and form a transversely extending dovetailed channel in the frame of the gun and install the gun sight mechanism in the channel. This has necessitated a time consuming operation which is relatively expensive. The present invention eliminates the necessity of altering the gun in any manner as the same may be positioned on the gun and automatically provides the rear gun sight in the proper location and elevation to enable the gun to be used as a target pistol in target practice.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being the intention to cover all changes and modifications of the example of the invention herein disclosedfor purposes of the disclosure, which do not constitute departures from the spirit and scope of the invention,

The invention is illustrated in the accompanying drawing, wherein:

Figure 1 is a side view of a portion of a service revolver showing the gun sight in position thereon.

Figure 2 is a rear view taken on line 2-2 of Figure 1.

Figure 3 is an enlarged top plan view of the gun sight.

Figure 4 is a front view taken on line 4-4 of Figure 3.

Figure 5 is a side view taken on line 5--5 of Figure 4.

Figure 6 is a vertical section taken on line 6-6 of Figure 5.

By referring to the drawings and Figures 1 and 2 in particular it will be seen that a revolver has been illustrated including a frame In, stocks barrel I2 and cylinder I3. The trigger is indicated by the numeral l4 and the hammer by the numeral 5. The gun sight comprising the invention is illustrated as being positioned on the uppermost portion of the frame l0 above and forward of the hammer l5. In Figures 1 and 2 of the drawings the body member of the gun sight is indicated by the numeral 6.

By referring to Figures 3, 4 and 5 of the drawings it will be seen that the body member 5 has depending end sections forming with the body member I'G an inverted U-shaped device of a width sufiicient to span the frame ID of the gun as shown in Figure 2 of the drawings. The depending end sections |'l-|| are positioned on the opposite sides of the frame In and are provided with drilled and tapped openings |8-|8 in which set screws Ill-l9 are positioned. The length of the depending end sections I1 is greater than one-half of the overall height of the body member IS. The set screws l9-l9 are adapted to be turned inwardly so as to forcibly engage the sides of the frame In of the gun and thereby position the body member I6 on the gun. The body member l6 has a transversely extending slot 20 in its uppermost portion. The slot 20 is relatively narrow and is adapted to receive a notched plate 2|, the notch therein being indicated by the numeral 22.

Transversely spaced drilled and tapped openings 2323 are provided in the body member l6 of the gun sight and set screws 24-24 are positioned therein so that their innermost ends project into the slot 20 for engagement against one side of the plate 2| therein. It will thus be seen that the plate 2| may be adjustably positioned in the slot 20 by loosening the set screws 24-24, positioning the plate 2| in desired position and re-tightening the set screws 24-24. In the event the elevation of the notched plate 2| is necessary, the same may be positioned in spaced relation to the bottom of the slot 20 or alternately a notched plate 2| of greater height may be substituted. In either event, the gun sight provides for both horizontal and vertical adjustment to enable the sight to be adjusted to the actual projectile path of the gun and with respect to a target whereby the gun may be zeroed in on the target.

In Figure 6 of the drawings the notched plate 2| is shown in plan view resting on the bottom of the slot 20 in the body member l6 of the gun sight. It will be observed that in the event it is necessary to lower the notched plate 2|, the bottom of the plate 2| may be cut off appropriately or, alternately, the bottom of the body member l6 between the depending ends I! may be cutaway slightly to adapt the gun sight to a particular gun frame.

It will thus be seen that the gun sight disclosed herein meets the several objects of the invention and provides an effective rear gun sight for a service revolver enabling the same to be used as a target pistol. A further advantage ofthe gun sight disclosed herein as compared with gun sights as known in the art is found in positioning the gun sight over the gun sight ordinarily machined in the frame ll) of the gun. In Figure 2 of the drawings it will be seen that the notch 22 in the plate 2| is directly above the notch in the frame of the gun thus providing a definite vertical guide enabling the gun to be aligned vertically with respect to the target which aids materially in accurate shooting. The notched gun sight in the frame I is indicated in Figure 2 by the numeral 25.

It will thus be seen that the several objects of A rear gun sight for a revolver to enable the same to be used as a target pistol, the said rear gun sight comprising a short inverted U-shaped body member, the arms of the said inverted U- shaped body member engaging the opposite sides of the frame of the said gun, a slot formed in the uppermost portion of the said inverted U- shaped body member so as to lie transversely of said gun and a notched plate disposed in said slot, drilled and tapped openings in the arms of the inverted U-shaped body member and set screws in the said drilled and tapped openings for frictional engagement with the opposite sides of the said frame of the gun, and secondary drilled and tapped openings in the transverse portion of the inverted U-shaped body member and at right angles to and communicating with the invention have been met by the gun sight disclosed herein.

Having thus described my invention, what I claim is:

the slot therein, set screws in the said secondary drilled and. tapped openings and engaging the said notched plate;
