6 Claims.

This invention relates in general to a gunsight assembly and more particularly to a gunsight assembly including a peepsight and means for adjusting the position of the peepsight horizontally and vertically.

The primary object of the present invention is to provide a simple, compact gunsight which can be made very economically and which is adapted to be adjusted easily in two directions at right angles to each other, the adjustment being made quickly and accurately.

A further object of the invention is to provide a gunsight of the peepsight type comprising certain parts which may be readily and economically die cast, which can be readily and quickly assembled and which are adapted for quick and accurate setting, which can be readily and economically manufactured, and which are not likely to get out of order.

The accompanying drawing illustrates a selected embodiment of the invention, and the views therein are as follows:

Fig. 1 is a fragmentary side elevation of a gun and having the improved gunsight applied thereto;

Fig. 2 is a detail sectional view on the line 2 2 of Fig. 1 and showing the improved gunsight in elevation;

Fig. 3 is a detail sectional view on the line 3-3 of Fig. 2;

Fig. 4 is a detail vertical sectional view taken at right angles to Fig. 3 and on the line 4-4 of Fig. 3; and

Fig. 5 is a detail plan sectional view of the improved gunsight on the line 5 5 of Fig. 3.

The particular gunsight herein shown for the purpose of illustrating the present invention comprises a base or supporting bracket I which is adapted to be secured rigidly to the stock 2 of a gun 3 in any preferable manner such as by attaching screws 4.

The supporting bracket I includes a relatively long rearwardly extending tongue-like part `5 which rests on top of the stock 2, there being holes in the part 5 to receive the attaching screws 4. An integral ear or lug 6 is formed at each side of the bracket I and extends upwardly from the forward end of the attaching tongue 5 as clearly shown in Figs. 4 and 5. Each integral ear 6 terminates at its upper end in a hollow cylindrical or barrel-shaped member 'I to receive and support adjustably the body 8 of the sight apparatus or device.

The body 8 is substantially in the form of a cross, Figs. 2 and 4, and comprises a central part 9, integral side arms Il), I0, an integral upwardly extending head I I, also in the form and shape of an arm I0, and a bottom leg I2 which is somewhat longer than the head part I I but of substantially the same diameter as the parts I0 and II. The body is adapted to be inserted between the inside edges I3, Figs. 4 and 5, of the barrel-shaped members 1, an arm I0 being received in a cylindrical opening I4 formed in the members l, Fig. 4. The width of the body 8, from the extreme outer ends of its arms, is greater than the distance between the inside edges I3, I3 of the members '1, and inasmuch as the body is to be inserted within that narrower space, one arm I0 of the body is made in two pieces I5 and I6, Fig. 4. The part I5 of one arm I0 is reduced in diameter at its outer end, and receives the part I6; the parts I5 and IE being secured together rigidly, such as by a tight press t or by a pin.

The bracket I, including the lugs 6, 6 and the members 1, 1, is preferably cast in one piece. The body `8 also is preferably cast in one piece. The body 8 is applied in position by first inserting the single integral arm Ill into a receiving opening I4, and then later positioning the extension part I6 through the other opening or hole I4. The opening I4 in one of the members 'I extends entirely through a member 'I (to the right, Fig. 4) to permit such assembly. The body 8 is thus free to be mounted between the edges I3, I3 of the members 1 with the arms mounted in the bearings provided by the holes or openings I4 in the members 1. The body 8, therefore, is free to have lateral horizontal movement in the hollow cylindrical members 1.

The body, also, may have pivotal movement about a horizontal axis, which movement is desirable from a packaging standpoint as the body may be collapsed against the tongue 5. It is not desirable to retain the collapsible feature during use of the device in actual practice because the body must be retained in proper Vertical position. The means to prevent the collapsibility of the device in actual use may comprise a groove I'l provided in one arm I0, which groove receives a feather or tongue I8 formed interiorly of a member l, Fig. 4. The tongue and groove construction, I8 and II respectively, is so constructed and arranged that pivotal movement about a horizontal axis is prevented at all times except when the body is at one extreme side position, such as when the body is moved to the extreme right as viewed in Fig. 4, the tongue and groove being out of registration when in such extreme right hand position. The tongue and groove are in registration in all other positions and, therefore, pivotal movement in such other positions is prevented.

Each arm l of the cross-like body is provided with a threaded opening to receive a set screw I9, one set screw being located at the left hand side while the other set screw is located at the right hand side. The heads 20 of the screws I9 bear against the outside edges of the members 1, Fig. 4, whereby the body may be locked tightly in position by tightening the set screw. Lateral horizontal adjustment of the'body may be had by loosening one set screw and tightening the other, whereby the body may be moved over a relatively wide range of adjustment.

The vertical part of the body is provided with a vertical opening 2| extending completely therethrough, the opening 2| preferably being noncircular in cross-section, such as square, Fig. 5. A square bar or rod 22 is mounted for vertical movement in this vertical opening 2|, and this -rod carries a circular head 23 through which there is provided a peep-sight or opening 24,

Figs.. 3 and 4. The rod 22 is adjustable vertically by a set screw 25 threadedly engaging a threaded bore 25 in the bar or rod 22. The head 21 of the set screw engages the under side of the bottom part of the bottom leg l2 of the body .8. The interior of the bore 26 at the bottom thereof is grooved as indicated at 28, Figs. 3 and 4, to receive a projection 29 on the set screw 25, particularly at the head 21 thereof. The ledge on the set screw may be locked into the groove in any conventional manner such as by pressing the metal of the body inwardly by a peening operation, or the like. This construction permits turning movement of the screw but prevents vertical or longitudinal translation of the screw. 'Ihe screw 25, therefore, causes vertical move- -ment of the rod 22 when the head 21 is rotated,

whereupon the peep hole 24 may be adjusted either upwardly or downwardly.

The peep opening 24 is adapted to be brought into proper adjusted position with respect to a sight (not shown) which may be mounted on the top of the gun barrel at the forward end thereof (near the muzzle). The sight opening 24 is lshifted horizontally, either to the right or to the left, by operating the knurled heads 20 of the l set screws I9, and is shifted vertically, either upwardly or downwardly, by operating the knurled head 21 of the set screw 25.

The rod 22 and its head 23 are integral and are preferably cast in one piece. gunsight therefore comprises relatively few parts, which include the integral bracket l, the integral body 8, the integral rod and head 22 and 23, respectively, and three set screws. The device therefore may be made at an extremely low cost. The relatively fine threads on the set screws permit relatively fine adjustment. The device is extremely accurate, may be manufactured at a verylow cost and may be applied easily and quickly in position to a gun. The drawing shows a tang sight construction but is applicable as a receiver sight by changing the form of the attaching bracket. It is believed that the present gunsight may be made more economically than the sight disclosed in my copending application Serial No. 520,402, filed January 31, 1944, now Patent No. 2,444,844, granted July 6, 1948.
