ARCHERY BOW Filed Oct. 18, 1959 ATTORNEYS Patented Jan. 14, 1941 UNITED STATES PATENT OFFICE 3 Claims.

This invention relates to archery bows, and its general object is to provide a bow that is made up of wood and steel to combine the rigidity and other necessary qualities of the former with the strength and resiliency of the latter, the steel portion being in the form of a rod like core embedded within and reinforcing a Wood shell like member and retains the bow in proper shape and flexible condition for a prolonged period of time under all weather conditions, it being well known that a bow made entirely of wood tends to lose its power, shape and tension in a short time, especially if not used and in damp weather, and becomes brittle, dead and easily broken if allowed to become too dry, but a bow constructed in accordance with my invention entirely eliminates those disadvantageous features.

A further object is to provide a combined wood and steel archery bow that is preferably made into sections or limbs detachably secured together so as to be separable, to take up minimum space in storage and transportation, as well as to facilitate handling the same when not in use, and the sections can be connected and separated with respect to each other in an easy and expeditious manner.

Another object is to provide an archery bow of the character set forth, that is simple in construction, inexpensive to manufacture and eX- tremely efcient in operation, use and service.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be herelnafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is a side elevation of a bow which forms the subject matter of the present invention.

Figure 2 is a longitudinal sectional view taken therethrough.

Figure 3 is a fragmentary enlarged sectional view clearly illustrating the means for detachably securing the sections together.

Figure 4 is a detail view of the rod members which provide the core for my bow.

Referring to the drawing in detail, it will be noted that the body of my bow, in the form shown includes a pair of identical sections or limbs I enlarged at their inner ends to provide a handle portion 2 when the sections are joined together.

While the handle portions 2 are preferably straight and directed toward the rear face of the body, as best shown in Figure 3, the remaining portions of the sections are curved from their juncture With the handle portions in gradually tapered formation and terminate at their outer ends in headed tips 3, the tips being substantially in the form of disks to provide abutment shoulders for the string 4 that has its ends wrapped about the sections to be fixed thereto, as shown. The use of the headed tips are preferable to notches or the like for receiving the string, as notches tend to weaken the bow, as will be apparent.

The important feature of my bow lies in the fact that it is made up of wood and steel as previously set forth, and for that purpose, each section or limb I includes an outer shell like member 5 made of wood, or in other wordsV the members 5 are bored longitudinally from the handle portions 2 to adjacent the tips 3, and mounted in the bores are steel rods 6 of a size to snugly t the same. The portions of the bores Within the enlarged or handle portions 2' are enlarged to provide recesses and one of the rods 6 has an interiorly threaded sleeve 1 formed on its inner end and ttingly mounted in its recess while the other rod has a threaded stud 8 formed on its inner end and of a length to extend beyond the inner end oi its wood member to be threadedly received within the sleeve as best shown in Figure 3, for detachably securing the sections together. The stud is likewise fittingly mounted within its recess.

The confronting ends or faces of the Wood members are flat and I preferably provide a metallic washer 9 between the same, with the faces in abutting engagement therewith.

From the above description and disclosure in the drawing, it will be obvious that the rods not only act to reinforce the bow, as well as add strength and resiliency thereto, as clearly set forth in the objects, but the joint for the rods likewise join the sections together in a manner whereby casual removal or displacement of the sections with respect to each other is practically impossible.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is tot be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

What I claim is:

1. An archery bow comprising a body including a pair of sections enlarged at their inner ends to provide a handle disposed midway the ends of the body, the sections being tapered inwardly from the enlarged portions at the outer ends thereof and bored longitudinally with the bores extending through the enlarged portions and terminating adjacent to the outer ends of the sections, resilient metallic reinforcing rods mounted in the bores, means formed on the rods for detachably securing the sections together, and a string secured to and bridging the outer ends of the sections.

2. An archery bow comprising a body including a pair of sections enlarged at their inner ends to provide a handle disposed midway the ends of the body, the sections being tapered inwardly from the enlarged portions to the outer ends thereof and bored longitudinally with the bores extending through the enlarged portions and terminating adjacent to the outer ends of the sections, resilient reinforcing metallic rods mounted in thev bores, a threaded sleeve formed on the inner end of one rod, a threaded stud formed on the inner end of the other rod and mounted in the sleeve for detachably securing the sections together, and a string secured to and bridging the outer ends of the sections.

3. An archery bow comprising a body including a pair of sections enlarged at their inner ends to provide a handle disposed midway the ends of the body, the sections being made from wood and tapered inwardly from the enlarged portions to the outer ends thereof, the sections being bored longitudinally with the bores extending through the enlarged portions and terminating adjacent the outer ends of the sections, resilient reinforcing metallic rods mounted in the bores, a threaded sleeve formed on the inner end of one rod, a threaded stud formed on the inner end of the other rod and mounted in the sleeve for detachably securing the sections together, a washer between the inner ends of the sections and providing abutment means therefor, a string secured to and bridging the outer ends of the sections and substantially disk shaped headed tips formed on the outer ends of the sections and providing abut- -ment means for the string.
