1 Claim. (CI. 33-51) Our invention relates generally to gun sights and, more particularly, to detachable auxiliary sights for indicating the correct lead when shooting at a target moving laterally across the line of vision of a hunter.

An important object of our invention is the provision of a lead sight which will indicate the correct lead without otherwise obscuring the vision of a hunter when sighting a gun.

Another object of our invention is the provision of a sight, as set forth, which can be quickly and easily applied to or removed from the barrel of a gun.

Another object of our invention is the provision of a lead sight which is simple and inexpensive to manufacture from a single relatively narrow strip of flexible material, which is exceedingly light in weight, and which is rugged in construction and durable in use.

Still another object of our invention is the provision of a lead sight, as set forth, which, when placed upon the barrel of a gun, will be locked against movements with respect to the barrel.

The above and other highly important objects and advantages of our invention will become apparent from the following detailed specification, appended claim and attached drawings.

Referring to the drawings, which illustrate the inven tion, and in which like characters indicate like parts throughout the several views:

Fig. 1 is a fragmentary view in plan of a gun barrel having our novel lead sight mounted thereon;

Fig. 2 is a view partly in elevation and partly in transverse section, taken on the line 2-2 of Fig. l; and

Fig. 3 is a view corresponding to Fig. 2 but showing a modified form of'the invention.

Our novel lead sight is preferably made from a relatively narrow strip of flexible resilient sheet material, such as spring steel or the like, and involves an integrally formed structure comprising a pair of loops 1 and 2 connected by a generally horizontal connecting arm 3. The connecting arm 3 is adapted to rest upon the top portion of a gun barrel or the like 4 and is provided with a central opening 5 in which is receivable the conventional bead sight 6 adjacent the front end of the barrel 4. The barrel 4 is presumably that of a conventional shot gun, not shown, the bead sight 6 being of the type commonly used with such fire arms.

As shown in Fig. 2, the loops 1 and 2 are formed to provide respective sighting bars 7 and 8, which extend radially inwardly to the centers of the loops. The sighting bars 7 and 8am horizontally disposed and, as shown, are located at a slightly higher level than but parallel to the connecting arm 3, and on a common level with the sighting bead 6 when the connecting bar 3 is in engagement with the top portion of the gun barrel 4. Otherwise stated, the connecting bar 3 and the sighting bars 7 and 8 have flat surfaces disposed substantially in a common plane that intersects the sight 6 and the axes of the sighting loops 1 and 2.

The free end portions of the material which forms the bottom halves of the sighting loops 1 and 2 are folded backwardly, as indicated at 9 and 10, respectively, to

ice

provide opposed arcuate gripping fingers 11 and 12, which embrace opposite side portions of the gun barrel 4 when the connecting arm 3 is in engagement with the top portion of the gun barrel. The inherent resiliency of the material comprising our novel lead sight permits the gripping fingers 11 and 12 to be easily spread apart so that the lead sight may be quickly and easily applied to the barrel. With the lead sight thus applied, and with the bead sight 6 received in the aperture 5 of the connecting arm 3, the lead sight is effectively held against movements circumferentially of the barrel 4.

With our novel leadsight applied to the gun barrel, as shown, the hunter utilizes the inner ends of the sighting bars 7 and-8- -selecti.vely depending on the direction of 15 movement of the game across the line of vision of the hunter. The broken lines X and Y indicate the line of sight from the hunters eye to the game when utilizing our novel sighting attachment. It will be noted, with reference to Fig. 2, that normal use of the conventional bead sight 6 is not impeded when shooting at game approaching in a direct line with the hunters line of vision. The lead sight of Figs. 1 and 2 is equally adaptable to the so-called over and under type of shot gun, the gripping fingers 11 and 12 engaging opposite side portions of the upper barrel of this type of gun.

The modified form of the invention illustrated in Fig. 3 is similar in all respects to that of Figs. 1 and 2, except that the arm 13 connecting the loops 1' and 2' thereof is longer than the arm 3 of the structure of Figs. 1 and 2- As shown, the modification of Fig. 3 is designed for use with a double-barreled shot gun, the barrel structure of which is indicated at 14. Also, as shown, the various components of the modified form of lead sight, such as the sighting bars and gripping fingers, identical to those of the sight of Figs. 1 and 2 carry the same reference characters with prime marks added.

Our invention has been thoroughly tested and found to be completely satisfactory for the accomplishment of the objectives set forth; and while we have shown and described a preferred form and a single modification of our improved g un sight, it will be understood that the same is capable of further modification without departure from the spirit and scope of the invention as defined in the claim.

What we claim is:

A lead sight for guns, said lead sight being made from a single relatively narrow strip of flexible resilient sheet material and comprising a pair of laterally-spaced sighting loops, a transversely extending bar element connecting said loops, said banelementmbeing adapted to rest upon the topportion of a. gunbarrel adjacent the front end thereof, a pair of gripping fingers adapted to embrace opposite side portions of said gun barrel, and a pair of sighting bars each comprising a section of said strip folded double upon itself and extending radially inwardly from the laterally outer peripheral portion of a different one of said sighting loops to the central portion thereof, said connecting arm having a central gun sight receiving opening therein, said gun sight when received within said opening preventing circumferential movement of the lead sight about said barrel, the connecting bar and the sighting bars having flat surfaces disposed substantially in a common plane that intersects the axes of the sighting loops.
