GUN -SIGHT.

Specification of Letters Patent.

Patented Oct. 19, 1909.

Application tiled January 11, 1909. Serial No. 471,574.

To all whom it may concern:

Be it known that I, JoHN A. KENNEDY, residing at Browning, in the county of Teton and State of Montana, have invented certain new and useful Improvements in Gun- Sights, of which the following is a specification.

My invention relates to a certain new and useful improvement on the gun sight disclosed in my former patents Nos. 535,379,

- granted March 12, 1895, and 592,7 49, granted October 26, 1897.

In its generic nature my invention seeks to provide a sight disclosed in my latter patent wherein an arc plate is provided by means of which the sight may be adjusted from the left side of the gun by the finger of the operator, and wherein the arc plate carries a rack segment to cooperate with a pin to hold the segment and its attached sight in the proper elevation, the arc plate being graduated to indicate the proper degrees of elevation.

More specifically my invention also embodies those novel details of construction, combination and arrangement of parts, all of which will be first described in detail and then be specifically pointed out in the appended claims, reference being had to the accompanying drawings, in which Figure 1, is a side elevation of a gun embodying my invention, showing the position of the parts when the sight is at its lowest position. Fig. 2, is a detail view showing the position of the parts with the sight elevated to its greatest elevation. Fig. 3, is a top plan view of the parts shown in Fig. 1. Fig. 4, is a side elevation of my improved sight detached from the gun. Fig. 5, is a cross section on the line 5 5 of Fig. 1.

Referring now to the accompanying drawings, in which like letters and numerals of reference indicate like parts in all of the figures 1 designates a pivot-bearing ear having a dove-tailed piece 1, by means of which the sight may be attached to a gun. The pivot-bearing ear 1 has a laterally projecting hub 1b on which the sight lever 2 is mounted, the sight lever 2 having an apertured bearing portion 2a through which the hub lb projects. Passing eccentrically through the hub 3EL of a regulator lever 3, and eccentrically throughthe pivot-bearing ear 1 and its hub 1b is a pivot pin 4 that has a squared portion 4a to tit a corresponding aperture in the hub 3fl of the regulator lever 3 so as to turn therewith.

5 designates a rack engaging pin carrying member whose hub 5 is bored to fit onto the hub 1b of the pivot-bearing ear 1 and is also apertured eccentrically as at 5b to permit passage of the pivot pin 4. Thus the pivotbearing ear 1 and the pin carrying member 5 are connected together as one. The pin carrying member 5 has a downwardly projecting shank 5C to receive the ratchet pin 5d that is provided with a beveled end 5e and a groove 5f to cooperate with the stop 5g to prevent turning of the pin 5d, a coil spring 5s being provided within the downwardly projecting portion 5c of the pin carrying member' to normally hold the pin in engagement with the rack segment hereinafter referred to.

6 designates an arc plate having a squared aperture Gf* to receive the squared end 4b of the pivot pin so as to turn with the pivot pin. The arc plate 6 is provided with a rack segment 6b to cooperate with the rack engaging pin 5d, hereinbefore referred to, to hold the sight in its adjusted position, as will be hereinafter more fully apparent. The arc plate 6 has an arc slot to exhibit the spring pressed rack engaging pin so that it may act as a pointer to coperate with the scale (Sh-on the front of the arc plate, as clearly shown in Fig. 1, of the drawings. The arc plate 6 is further provided with a milled thumb piece 6I by means of which the arc plate may be moved to change the position of the sight.

10 designates the sight piece which is provided with a pair of ears to receive an ear 2e of the sight lever and through which a pivot pin 10a passes, the sight lever having a shoulder 2c to cooperate with a shoulder 10c of the sight piece 10 to limit the movement of the sight piece on the pivot in one direction and the sight lever 2 is provided with another shoulder 2d, to cooperate with a 100 second shoulder 101 of the sight piece to limit its movement in an opposite direction. The sight piece 10 is provided with another pair of ears 10i and 10g between which the regulator lever 3, is pivoted on the pin 10h. 105

It is to be noted that the pivot pin l()h and the pivot pin 10b do not lie in the same alinement.

When the parts are in the position, shown in Fig. l, the sight will be at its lowermost 110 position to cooperate With the front sight l5 of the gun and by moving the arc plate through the medium of the milled thumb piece, the sight may be raised to any desired elevation and vice versa. By reason of the connection between the pivot-bearing ear l and the sight piece l0, as the sight piece is moved from one position to another its rear Wall l0W Will lie in a plane at right angles t0 the line of sight at all times, as vvill be readily understood by reference to the dravvings. Y

By providing a sight constructed substantially as herein described, With the thumb actuated arc plate on the left side of the gun, a much more easy adjustment of the sight can be made, as the operator supporting the gun With his left hand can actuate the sight With the thumb of his left hand, While having his right hand free for actuating the trigger. Thus the position of the sight can be changed almost instantaneously to suit the particular requirements at the time. The position of the teeth of the rack 6b corresponds to the markings on the scale 6X, and the scale is graduated to indicate the various desired elevations of the sight.

From the foregoing description taken in connection with the accompanying drawings, it is thought the complete construction, operation and many advantages of my invention Will be readily understood by those skilled in the art to Which my invention ap-y pertains.
