Application January 16, 1946, Serial No. 641,487

1 Claim.

This application relates to hinged bows, such.

as are used in archery. A hinged bow consists of a bow which is split transversely at the handle.

Means are provided for movably but non-detach- 1asbly connecting the upper and lower limbs of the connecting means herein disclosed will now be It is an object of the present invention to provide a novel and improved hinge for connecting the upper and lower limbs of a split bow. The

If desired, although it is not necessary, a piloting means such as a pilot pin 2| may be secured described upon reference to the appended drawing.

In this drawing,

Fig. 1 is a front view showing a section of a hinged bow at the handle, with the hinge in place.

Fig. 2 is a view as if from the right of Fig. 1.

Fig. 3 is a view like Fig. 2 but showing the with numerous identical teeth adapted to interfit I or mate with similar teeth formed at the ends of a third plate It which straddles the split line l2 or lies over it. When the third plate It is so disposed with respect to the plates I l that the interfitting or mating teeth at the ends of the third plate 16 mate or interfit with the teeth at the ends of the two plates extending transversely of the three plates may pass through alined apertures of the teeth for pivotally connecting the three plates at their ends to one another and thus form a three element hinge.

When the bow is extended, and the parts are properly mounted and interfltted, the three platestogether form an uninterrupted smooth face hinge overlying the outer surface of the bow and covering the split l2.

Thus, the three plates and their hinge pins lie fiat against the bow, presenting no bumps or bulges to interfere with or impair proper operation and shooting.

i4, hinged pins l8 to one of the limbs as by being threaded into it, to seat itself in a piloting notch 22 of the other limb, and thus help in locating the two limbs as they are moved to each other so as to be connected so as to form a complete extended bow.

addition, if desired, a thin rubber cushion 23 may be secured adhesively to one of the limbs ,to prevent noises from arising due to the contact of the butt ends of the limbs, during shooting.

When the bow is collapsed as indicated in Fig. 3, the intermediate plate l8 separates the limbs from each other and yet maintains the two limbs in relative assembly.

Now having described the hinged bow herein disclosed, reference should be had to the claim which follows:

I claim:

A hinged bow split transversely at thehandle and having upper and lower limbs engaging at the split line, hinge means for connecting the upper and lower limbs comprising two small flat plates .immovably fastened to such limbs 0n the outer surface thereof, and a third plate connected at its ends to the ends of the first named two plates by transverse hinge pins, the first two plates having their adjacent ends remote from the bow split, with the latter being between such adjacent ends, and the third plate straddling such split, whereby a three element hinge is formed by the three plates, with the third plate covering the bow split, the three plates being formed so that, when the bow is extended for shooting, they form an uninterrupted smooth faced hinge overlying the outer surface of the bow.
