United States Patent GUN SIGHT Cass S. Hough, Plymouth, Mich., assignor to Daisy Manufacturing Company, Plymouth, Mich., a corporation of Michigan Application March 1, 1954, Serial No. 413,088

2 Claims. (Cl. 33--54) This invention relates generally to gun sights and more particularly to an improved rear sight which can be adjusted to provide either a peep sight or an open sight.

It is well known that in the firing of guns, either firearms or pneumatic guns, dilferent targets are presented under different conditions and certain types of sights are more desirable for certain targets than for others. The two most commonly used rear sights are the peep sight, which is normally a small round aperture in a plate through which the user sights on the target in conjunction with the front sight, and the other well known sight is the so-called open sight which is generally a V-notch extending inwardly or downwardly from the substantially fiat upper edge of the sight. Each sight has its advantages and disadvantages and it is therefore desirable to provide both types of sights on a gun to increase its versatility. able to adjust the same both for elevation and windage.

It is therefore an object of this invention to provide an improved gun rear sight which embodies both a peep sight and an open sight, either of which can be presented for use easily and quickly and wherein the sight which is not being used is out of interfering relationship with the sight which is being used.

It is a further object of this invention to provide a novel rear sight structure in which the sight can be easily adjusted both for elevation and windage.

It is a still further object of this invention to provide a sight of the aforementioned type which is relatively inexpensive, composed of relatively few parts, and which is durable and efficient in operation.

These and other objects of this invention will become apparent from the following detailed description, taken in conjunction with the accompanying drawing, in which:

Figure 1 is a side elevational view of an air rifle having the sight of this invention mounted thereon;

Fig. 2 is a fragmentary top plan view of the sight mounted on the rifle;

Fig. 3 is an enlarged fragmentary side view, partially in section and partially in elevation, of the intermediate portion of an air rifle having the sight of this invention mounted thereon with the open sight in an upstanding operative position;

Fig. 4 is a fragmentary sectional view of the sight shown with the peep sight in an upstanding operative position;

Fig. 5 is an enlarged sectional view of the structure illustrated in Fig. 3, taken along the line 5-5 thereof; and

Fig. 6 is a fragmentary view, partly in section and partly in elevation, taken along the line 6-6 of Fig. 3.

Referring now to the drawing it will be seen that an air rifle 7 is illustrated with the rear sight 9 mounted thereon and a front sight 11 mounted adjacent the frontof the rifle barrel housing 13. It will, of course, be appreciated that the rear sight device of this invention is not limited in use to air rifles but may be used on various other types of weapons. The air rifle 7 includes a frame structure 15, a stock 17, connected with the frame in any suitable manner, a cocking lever 19 pivotally mounted on the frame for cocking the operating plunger 21 of the rifle. A trigger 23 is illustrated as being pivotally connected with the frame and engageable with the plunger mechanism 21 so that when squeezed it will release the plunger mechanism for forward movement under the impetus of a spring 25.

The sight 9 is mounted on the top of the frame 15 above the trigger 23, which is, of course, the conventional sight mounting position. The sight includes an elongated platelike member 27, the front end of which is spot welded or the like at 29 to the frame. A screw 31 is threadably supported in the platelike member 27 rearwardly of the front end thereof. The frame is provided with a slot 33 in the upper side thereof, which It likewise is desirable in rear sights, to be slot is enlarged at 35 at the back end thereof. The screw 31 has a downwardly extending shank 37 and an enlarged head 39 on the lower end of the shank. When the sight is assembled to the frame the head 39 of the screw 31 is inserted into the enlarged end 35 of the frame slot 33. The plate member 27 is then slid forwardly until the head 39 of the screw is disposed beneath the smaller end of slot 33, where it cannot be pulled vertically upwardly therepast. The front end of the plate member 27 is then welded to the frame at 29, as previously described. Therefore, by turning screw 31, the rear portion of the platelike member 27 can be moved upwardly or downwardly to vary the elevation of the sight mechanism.

A sight base 41 is supported on the rear portion of the platelike member 27. The sight base is illustrated as being of a one piece sheet metal construction having a plate portion 43, which rests upon the upper surface of the platelike member 27 and has a transversely elongated opening 45 therein disposed above a threaded opening 47 in the plate member 27. A screw 49 has its threaded shank portion extending through the transversely elongated slot 45 in the base and threaded into the threaded opening 47 in the plate member 27. By loosening the screw the base member may be shifted transversely of the gun frame for windage correction. The base 41 has upstanding spaced apart side flanges 51 on opposite sides thereof. The flanges are provided with rearwardly extending projections 53 which straddle an upstanding flange 55 on the rear end of plate member 27. The flanges 53 and 55 cooperate to limit the transverse or lateral movement of the rear portion of the sight base relative to the plate member 27. The base flanges 51 are apertured and at least one is threaded to receive a pinlike screw 59 which extends between the flanges above the bottom of the base. A sight 61 is supported on the base and includes a platelike portion 63 having a round aperture 65 therein forming a peep sight and a platelike portion 67 having the upper or outer edge 69 thereof substantially straight and flat and having a V-shaped notch 71 extending inwardly from the edge to provide an open sight. The sight 61 is illustrated as being of a one piece sheet metal construction and having a loop portion 73 at the junction of plate portions 63 and 67 which are angularly disposed relative to each other substantially The threaded pinlike member 59 extends through the looplike portion 73 of the sight so that the sight is journalled thereon for pivotal movement. The sight base flanges 51 are provided with abutments 77, fore and aft the screw 59, which are adapted to engage the platelike portions 63 and 67 of the sight and limit the movement of the sight to substantially 90.

Thus, if it is desired to use a peep sight, the user of the gun merely pivots the sight 61 until the plate portion 67 engages the abutments 77, thus positioning the plate portion 63 in an upright position. If it is desired thereafter to use the open sight, the user merely flips the plate portion 63 forwardly until it engages the abutments 77, at which time the plate portion 67 will be in the upright position, as illustrated in Fig. 3, so that the user has an open sight on which to sight the target.

It will thus be appreciated that the device of this invention provides a combination open and peep sight, as well as a sight which can be adjusted for both elevation and windage, and a sight which is inexpensive to manufacture, durable in construction and eflicient in operation.

What is claimed is:

1. In a gun rear sight device a sheet metal base member having spaced apart upstanding flanges on the opposite sides thereof, a one piece sheet metal rear sight including plate portions angularly disposed substantially 90", a looplike portion at the junction of said plate portions, a pinlike member carried by and extending between said spaced apart base member flanges, said sight loop portion being journalled on said pinlike member so that said sight can be swung between a first position wherein one of said sight portions is disposed in a generally vertical upstanding position and the other sight portion is disposed in a generally horizontal position, and a second position wherein said one sight portion is disposed in a generally horizontal position and said other sight portion is disposed in a generally vertical upstanding position, said base flanges having abutment means thereon fore and aft of said pinlike member, one of which engages the horizontally disposed of said sight portions when said sight is in one position and the other of which engages the other of said sight portions when said sight is swung to its other position, one of said sight platelike portions having an aperture therein to provide a peep sight, the other of said sight plate portions having a V-shaped notch adjacent one edge thereof, the center of said notch and the center of said peep sight aperture being disposed in alignment with each other.
