This invention relates to gun sights and particularly to adjustable rear sights especially of the peep type.

Objects of the invention include the provision of a rear gun sight having extremely easily adjustable means for varying the elevation, said sight being simple in nature and inexpensive to manufacture, without, however, losing effectiveness, accuracy, or ease of manipulation.

Other objects and advantages will appear hereinafter.

Reference is to be had to the accompanying drawing, in which Fig. 1 is a top plan view of the new gun sight, parts being in section;

Fig. 2 is a vertical cross section longitudinally of the gun sight;

Fig. 3 is a view in side elevation thereof;

Fig. 4 is a view in side elevation of the adjustable spring strip;

Fig. 5 is a bottom plan view thereof, and

Fig. 6 is a rear elevational view of the sight looking in the direction of arrow 6 in Fig. 3.

The present gun sight may be attached to the receiver of the rifle or other weapon by any convenient or desired means, but in the present instance the securing means is shown as a keystone or dovetailed base III which fits into a complementary slot arranged transversely of the rifle barrel. The base I 0 is provided with a pair of parallel upstanding side walls I 2 and I4 which are triangular in form, having their narrowest edge portions forwardly relative to the base l0 so that a wide edge is located to the rear as at l6, for purposes to be described. Side wall I2 is beveled off at its rear end as at l8 and in the area of this bevel side wall I2 is engraved by markings 20 indicating the elevation in yards. Also the rear ends of walls I2 and I4 are correspondingly notched as at 22. A pin 24 is set into side walls l2 and I4 adjacent the forward end of the sight, close to the upper surface of the base plate ID. A generally L-shaped spring strip 26 is provided with eyes 28 which are hooked over the pin 24 so that the latter acts as a pintle to provide for a swinging movement of the spring arm 28 thereabout, it being noted that the spring arm is positioned between the two walls l2 and l 4.

Spring arm 26 is provided with an upstanding foot 30 terminating in a finger grip 32 and at the angle forming the foot there are out out portions at 34 which easily provide for a slight bending of the foot 30 relative to the leg of the spring upon manual manipulation of the finger grip 32 towards the right in the drawing. The foot 30 is also provided with a laterally extending element 36 which terminates in a bent ove pointer 38; and it will be noted in Fig. 1 that the pointer 38 is confined to a position wherein it cannot extend beyond the outer surface of wall I 2 but still overlaps the beveled portion l8 of this wall. The pointer 38, of course, indicates the range of the firearm by varying elevations of the spring and it will be seen that the sight is set at yards in Fig. 3. The element 36 is depressed at 40 and a corresponding element 42 without a pointer is similarly depressed at the other side of the spring foot 30 so that the depressions will snap into the notches 22 at whatever elevation is selected to hold the sight in this position. The spring foot 30 is also provided with a vertical slot 44.

A special hollow screw 46 having a flange 48 extends thru slot 44 and provides the peep sight. A hollow internally threaded nut 50 is used to clamp the Deep sight 46 to the spring foot 30 in the above manner as illustrated in Fig. 2. The peep sight 46 is adjustable vertically in slot 44 merely by loosening nut 50 and retightening the same where desired.

It is believed that the operation and adjustment of the device will be apparent from the above description when taken in conjunction with the drawing, it being noted however that the side walls I2 provides a pair of shoulders at 52 which define upper and lower limits in conjunction with the pointer 38 to prevent disassembly or excess adjustment. To change the elevation, finger grip 32 merely needs to be pressed slightly by the finger so as to swing the spring foot 30 away from rear edges l6, thereby disengaging the depressions in

elements

36 and 42 from their notches, and then the sight may be adjusted by swinging the spring arm on the pintle 24. The sight can be zeroized and the rifle can be targeted in by taking advantage of slot 44 and adjusting the peep sight relative to the spring foot until proper shooting is obtained.

While a particular form of the invention has been illustrated and described, it is to be understood that many modifications may be made therein by any person skilled in the art without departing from the spirit oi the invention as expressed in the claims. Therefore, I do not wish to be limited to the particular construction shown, but having fully described the invention and ascertained the manner in which the same is to be performed, what is claimed and sought to be'secured by Letters Patent is:

1. As an article of manufacture, a base late adapted for attachment to a firearm, said base plate being provided with a pair of upwardly extending side walls, said side walls having correspondin end edges notched, an arm swingably mounted in the device and having an angular end spring portion means on the latter cooperating with said notches for latching the spring arm in various adjusted positions relative to the base, and means in the spring arm providing a sight.

2. A gun sight comprising a support, means for securing the support to a gun, apivot element on the support, a spring steel strip mounted to swing on the pivot element, an upstanding end portion on the strip, cooperating latching means on the support and sprin end portion for locating the strip in adjusted positions relative to the former, 15

a sighting aperture through the'spring strip, said spring strip being manually adjustableby springing the same to disengage said latching means.

3. A device of the class described a base plate, a pair of upwardly extending walls on the base plate, a generally L-shaped spring arm swingably mounted 'on the device, means resiliently latching the spring arm in variable positions of adjustment thereon, a portion of said spring arm extending upwardly, means forming "a slot in said portion, a hollow element forming a peepsight extending through said slot, and means adjustably securing said element in desired position in said slot. v
