HOOK.

SPECIFICATION forming part of Letters Patent No. 498,630, dated May 30, 1893.

I Application ledMay 16,1892. Serial No. 433,143. (No model.)

T0 all whom it may concern:

Be itknown that l, EZRA'DEDERICK, of Milwaukee, in the county of Miiwau kee and State of Wisconsin, have invented a new and useful Improvement in Hooks, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

My invention has relation to that class of hooks which, though not necessarily so em-v ployed,arec01nrnonly usedtopreventbit-rings, hams-rings, breech-rings, andthe like, from accidental disengagement with the `object to which they are attached. It may also be convenientlyemployedin connection withblanket straps, and in rubber goods of small form, as well as upon clothing for the purpose of securing parts thereof together.

The primary object had in view is to provide, in a simple form, a hook which will not only possess the requisite strength to withstand the strain to which devices of this character are necessarily subjected, but, at the saine time, combine therewith that degree of elasticity which is necessary and desirable in order to provide for the ready insertion and removal of the ring, or other object, as Well as its secure retention in place, so that it will not be detached except und er considerable direct eort or extrinsic power applied therefor.

With the above primary object in view the invention consists in the improved construction as hereinafter more fully set forth.

In the accompanying drawings, Figure 1, isY a plan view-of my device. Fig. 2, is a side view, parts being shown in section, and Fig. 3, is a view showing the metal blank doubled back upon itself prior to its being bent over into proper hook shape. p

Like letters of reference designate like parts throughout the several views.

Referring to the drawings, the letter A indicates a metal blank. This blank consists of asingle piece of slightly elastic sheet metal bent over upon itself, as indicated by the letter a. As the metal is preferably of tapering form, the width of the bent over portion is, somewhat less than the width of the main part of the blank, as clearly illustrated in Fig. 3, which shows the blank doubled upon itself before it is given the requisite hook shape depreferably at the freeend of the bill,a4, upon the inner side thereof, and extends therefrom toward the curved part, obliquelyto the shank,

and is then extended obliquely and upwardly, forming an approximate 'V- shape, although` the corners or bends are rounded, as fully shown, in order not to present any sharp angles or projections against which the ring, or other attached part, could catch and accidentally force the bill far enoughaway from the shank to allow of disengagement.

It will be understood that the bent over strip is not attached by rivets or otherwise to the main part of the hook, but merely lies closely thereagainst except opposite the catch d3 so as to coincide exactly to its contour. The only point at which said doubled over` strip is held to the metal is at the rear end, where it is bent under and firmly gripped to the outer side of the shank, without, however, the employment of any rivets. This bend completely lls up the notch d5, so as to bring the edge of said bend liush with the bordering edge of the loop.

lt will be seen that my improved hook is made entirely from asingle piece of fiat metal, and is not only simple vin form, but inexpensive of production and insures an absolutely safe and secure means against detachment under'all ordinary circumstances. It is also to benoted that any sidewise force exerted by the animal against the hook, instead of having a tendency to detach the connecting part, as is the case with hooks of the ordinary construction, in my device, will have the effeet of springing the parts closer together, which constitutes quite an advantage over hooks of the ordinaryform abovereferred to.

From the foregoing description, it is thought that the construction and advantages of my deVice will be readily understood and appreciated. It will be apparent that by bending over the portion, a, increased strength is obtained from a uniform thickness of metal, and at the same time a maximum degree of elasticity or resiliency procured, with a reinforced and strengthened surface at the bend against Which the pull and strain of the attached strap are directed. If ametal were employed having the thickness attained by my construction, it is obvious that all, or practically all, elasticity would be destroyed.

It is of course desirable that not only should the catch a3, be flexible, but also the bill a4, and shank A, so that said bill and shank will lie in' close enoughy proximity to bring the catch a3, the requisite distance from the shank, and to allow them to spring back to such position after the catch has been acted upon either in attaching or detachin g the eye. This my construction readily admits of.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

l. A hook constructed of an integral strip of elastic sheet metal and substantially as described, combining a loop, a shank, a bend, a bill, an inwardly projecting catch on the inside and near the free end of the bill, an inner layer or reinforcing strip along and conforming,r to the bend and shank and secured to the shank at its rear end.

2. A hook constructed of an integral strip of elastic metal, combining a shank, a bend, a bill, an .inner superimposed layer or reinforcing strip along and conforming to the bend and shank, and a laterally extending catch, substantially as set forth.

In testimony whereof I ax my signaturein presence. of two Witnesses.
