LEAD SIGHT FOR, FIREARMS.

Application filed August 15, 1925. Serial No. 50,386.

My present invention has for its object to provide lead sights'for firearms, and to this end it consists of the novel devices and coinbinations of devices hereinafter described and defined in the claim.

As is well known, it is very difficult for the average hunter, and particularly the novice, to accurately gauge the proper lead or distance that one must shoot ahead of moving objects or flying game birds in order to hit the same. In one form of the invention, re-' movable front and rear lead sights are provided and each sight includes, the former a pair of beads and the latter a pair of sight openings through which said beads may be seen. Said pairs of beads and sight openings are horizontally and transversely spaced in respect to the barrel of a firearm and located equidistant from the axis of said barrel. The beads on the front lead sight are located a greater distance from the axis of the barrelpoint on the projected axis of the barrel of said fire arm. Said focal point being on the projected axis of the barrel of the fire arm, is at the intersection of lines extending through the beads and sight openings on opposite sides of the barrel of the fire arm, and which focal point may be located by the hunter moving his head either back or forth along the projected axis of the barrel of the fire arm.

The invention further provides for the use of a pair of horizontally and transversely spaced beads on the front lead sight on each side of the axis of the barrel of the firearm, for use in near and far shooting. Said invention further provides a front lead sight having beads that may be horizontally adj listed tow rd and from the axis of the bar rel of the firearm. The invention also provides lead sights having attaching means for detachably securing the same to a firearm, and which sights, after a hunter has learned to accurately gauge the proper lead, may be removed from the barrel of the firearm.

In the accompanying drawings, which illustrate the invention, like characters inclicate like parts throughout the several views.

Referring to the drawings:

Fig. 1 is a side elevation of a single barrel shot gun having a pair of the front and rear lead sights applied thereto;

Fig. 2 is a plan view of the same;

Fig. 3 is a view looking into the muzzle of the gun barrel and at the front lead sight, on an enlarged scale;

Fig. 4 is a plan view of the parts shown in Fig. 3;

Fig. 5 is an elevation of the rear lead sight removed from the gun;

Fig. 6 is a fragmentary detail view in elevation, showing a modification of the front lead sight;

Fig. 7 is a plan view of the same;

Fig. 8 is a view corresponding to Fig. 3, but showing a modification of the front lead sight;

Fig. 9 is a side elevation of said modification; and

Fig. 10 is a fragmentary plan view of the modification.

Referring first to Figs. 1 to 7, inclusive, there is illustrated a single barrel shot gun, and of the parts thereof it is important to note the breech 8, barrel 9, and front sight or bead 10.

As previously stated, the preferred form of the invention provides a front lead sight 11 and a read lead sight 12. Said front lead sight 11 comprises a horizontal bar 13 having at its longitudinal center a clamp comprising a pair of depending segmental spring jaws 14 adapted to be sprung around the barrel 9 for detachably securing said bar transversely thereto. In the center of the bar 13 is a hole 15 through which the bead 10 projects and thereby properly positions the front lead sight 11 on the barrel 9 and holds the same against turning or axil movements on said barrel.

Cutand pressed from the bar 13 is a pair of upstanding inner beads 16 and a pair of upstanding outer beads 17, and the beads of each pair are located on opposite sides of the barrel 9, equi-distant from the axis thereof.

By reference to Fig. 4, it will be noted that the beads 10, 16 and 17 are all on the same line, and which line extends transi 'ersely of the barrel 9 at right angles to the axis thereof.

The rear lead sight 12 comprises a short transverse bar 18 having a clamp in the form of a pair of spring jaws 19 at the ends of said bar and adapted to yieldingly engage the sides of the breech 8 and detachably secure said sight thereto. A pair of horizontal and laterally spaced sight openings 20 is formed in the rear sight 12 by folding the bar 18 at its end portions to form pairs of late ally spaced upstanding lugs 21. As shown, each lead sight 11 and 12 is formed from a single piece of spring steel, but, of course, may be made from any suitable material and in any desired shape.

To take aim at a moving object or a flying game bird, the hunter may first sight along the barrel 9, using the bead 10, in the customary manner, and then swing the muzzle of said barrel until one of the beads 16 or 17. (depending on the distance the shot is to be made. and on the side of the barrel t) in which the same being swung), may be seen through the sight opening 20 on the same side of the barrel 9. In taking the last noted aim, the hunter simply moves his head either forward or backward along the projected axis of the barrel 9 to find the focal. point, so as to bring one of the beads 16 or 17 into alignment with one of the sight openings 20. Some hunters may prefer to take a direct sight simply by using the lead sights and not the gun sight.

Referring now to the modification shown in Figs. (5 and 7, the horizontal bar 22 of a front lead sight 23 is provided on each side of its longitudinal center with a pair of laterally spaced beads 24, (only one side being shown), having depending stems 25 which project through longitudinal slots 26 in said bar. On the lower ends of the stems 25 are thumb nuts 27, by which the beads 2i may be clamped onto the bar 22 in different adjustments toward and from the axis of a gun barrel.

Referring now to the modification illus trated in Figs. 8, 9 and 10, the horizontal transverse bar 28 comprises two duplicate sections having at their abutting ends depending segmental clamping figures 29 adapted to snugly fit around a gun barrel Ill). These members of the bar 28 are conneeted and held clamped on the gun barrel Flt) by a C-shaped spring 31 loosely oncircling the clamping lingers 2!) with only their ends engaging the same at the members of the bar 28. The end portions of he spring 31 are bifurcated to receive reinforcing webs 32 between the members of the bar 28 and the clamping fingers 29. By thus bifurcating the end portions of the spring 31, the same is held interlocked with the lead sight and keeps the members thereof assembled. The abutting ends of the members of the bar 28 have formed therein half seats 33 arranged to receive the front sight 34: on the gun barrel 30 and thereby sccurely hold the lead sight against axial or circumferential movement on the gun barrel 30. llpstanding inner and outer pairs of beads 35 and 36 are secured to the members of the bar 26. It will be noted that the pairs of seats 16, ll', 35 and 36 are located materially outward of the sides of the gun barrels in order to give the proper lead.

To remove the lead sight shown in Fig. 8 from the gun barrel 30, it is only necessary to draw the outer end of the bar 28 downward to separate the inner ends thereof and release the half seats 33 from the sight 3%, and then move said lead sight axially from the outer end of its gun barrel 30.

The words beads and sight openings are used in a broad sense to cover any kind of sight guides.

The above described front and rear lead sights may be very easily and quickly ap' plied to a firearm or removed therefrom, and they are extremely simple and of comparatively small cost to manufacture. If desired, a hunter may use only the front lead sight and dispense with the rear lead sight.

What I claim is:

A lead sight for firearms comprising a flat straight horizontal bar, the end portions of which are folded inward under the intermediate portion of said bar and terminate in spaced reversely formed areuate spring--jaws applicable to grip -the barrel of a. tirearlifis ai d banha ving a gun sight. aperture niidway between said jaws, and a pair of sighting beads on said bar located one on each side of said aperture respectively.

In testimony whereof I aiiix my signature.

ADOLITI STORU.
