HINGE Filed s t. 22, 1937 INVENTOR ROBERT s. WAGNER ATTORNEY Patented Jan. 30, 1940 1 PATENT OFFICE 2,188,670 HINGE Robert S. Wagner, Milwaukee, Wis., assignor to E. R. Wagner Manufacturing Company, Milwaukee, Wis., a corporation of Wisconsin Application September 22, 1937, Serial No. 165,040

2 Claims.

This invention relates in general to hinges and more particularly to hinges of the type which have prongs for securing themto the parts which they hingedly connect. I One of the objects of the invention is to provide a hinge of this character which has its prongs so constructed as to be capable of being driven in and firmly secured to even very thin pieces of various materials without danger of splitting or cracking the same. For example, the prongs may be readily driven into thin piecesoi' hard wood without danger of splitting.

Another object of the invention is to provide a hinge of this character and having these advantages and which is simple and durable in construction, attractive in appearance, reliable and effective in use, and easy and comparatively inexpensive to manufacture and apply.

Other objects and advantages reside in certain and combination of parts which will be hereinafter more fully described and particularly pointed out in the appended claims, reference being had to the accompanying drawing forming 5 a part of this specification and in which:

Figure 1 is a fragmentary view in elevation showing a hinge embodying the present invention;

Figure 2 is a fragmentary view in transverse section taken on line 2-2 of Figure 1;

Figure 3 is a view in cross section taken on line 3-3 of Figure 2 and showing the construction of the prongs with which the hinge is equipped;

Figures 4, 5, 6, 7 and 8 are views similar to Figure 3 but illustrating modified prong constructions; and V Figure 9 is a fragmentary perspective view further illustrating the prong structure shown in Figures 2 and 3.

In the drawing the hinge is designated generally at H and isshown applied between a box B and its cover C, the box and the cover being constructed of thin pieces of hard wood or of any other suitablernaterial. I

The hinge illustrated comprises a pair of leaves designated at it) and H which may be formed with integral interfitted hinged barrels l2 pivotally interconnected by means of a hinge pintle pin I3. The leaves proper may be of any suitable structure or design. Usually they are ornamental in character and specially so when applied to jewelry boxes or the like. Each leaf of the hinge is provided with one or more prongs novel features of the construction, arrangement.

designated generally at I4 and in the structure illustrated the outer edge of each leaf is provided with one such prong adjacent each end. The prongs are stamped from the same piece of metal which makes up the leaf with which they 5 are integral.

In Figures 2, 3 and 9 the prongs are shown as being of curved or concavo-convex cross section and terminate in pointed ends Hi. In many instances it is desirable to have the curved cross section of the prong of the character shown in Figure 3 and the prong when so formed presents side edges Hi. When such a prong is driven into the wood of the box or cover the edges cut across the grain to effectively prevent a wedging action of such a character as to result in splitting of the Wood and consequently the fastening or securing action is enhanced. This action of the prong results from the fact that the side edges which exert the cutting action are presented 20 laterally or transversely to the fibers of the wood and hence will cut them rather than wedge them apart. Moreover, the body of the prong being displaced laterally from the mean plane of the prong also lies laterally or transversely of the wood fibers and hence will not Wedge them apart. In some instances it may be desirable to have the prong of a more pronounced curvature in cross section as shown at I! in Figure 4. The advantages of the invention may be approximated with other cross sectional shapes for example, the prong may have a rather pronouncedly curved body l8 and lateral flanges I 9 as shown in Figure 5 or the curvature of the body may be fiattened as shown at 20 in Figure 6 or may be made V-shaped as indicated at M in Figure 7. In Figure 7 the V-shaped prong has lateral flanges 22 but as indicated in Figure 8 these may be omitted and the prong assembly have the V- shaped cross section. indicated at 23.

In any event, the important feature of the invention is to have a prong of channel or curved cross section and provided with edge formations of such character thatthey will cut across the grain. of the wood and avoid any such wedging action as to result in splitting.

The prongs may be simply embedded in the wood or they may completely penetrate it and be clamped over as indicated at M in Figure 2.

While Ihave shown and described several constructions in which the invention may be advantageously embodied, it is to be understood that the constructions shown have been selected merely for the purpose of illustration. or example and that various changes in the size, shape and arrangement of the parts may be made without departing from the spirit of the invention or the scope of the subjoined claims.

The invention claimed is:

1. A hinge having pivotally interconnected lightweight sheet metal leaves, and a prong integral Withone of said leaves, said prong having a mean plane parallel to the axis of said pivotal 10 interconnection and being curved transversely in cross section to provideedges disposed from said I mean plane.

2. A hinge leaves, one of said leaves having a rear edge parallel with the axis of said pivotal intercon nection, a prong integrally formed on said edge,

having pivotally interconnected said prong being of concavo-convex cross section throughout its length, the axis of said cross section being disposed perpendicularly to said edge.
