UNITED STATES JACOB POOLE, 0F HAMDEN, NEW YORK.

HOOK-AND-EYE FASTENER.

Application filed January 16, 1924. Serial No. 686,568.

To all whom it may concern:

Be it known that I, JACOB POOLE, a citizen of the United States, residing at Ham den, in the county of Delaware and State of New York, have invented certain new and useful Improvements in Hook-and-Eye Fasteners, of which the following is a specification.

This invention relates to hook and eye fasteners, and has for its primary object to produce a hook and eye which will not become accidently disengaged. It is a matter of common experience that the ordinary form of hook and eye is very likely to have its members disengaged unless said members are kept under tension. Various attempts have heretofore been made to produce hook and eye which will maintain their engagement under all conditions of use, but so far as I am aware the prior constructions designed to produce this result have either re quired the application of considerable force to effect engagement of the hook with the eye, which of course is a very serious disadvantage in a device of this character, or have involved constructional complications which render the manufacturing operations diflicult and expensive. The hook and eye of the present invention is of very simple construction and can be operated with great facility.

Referring to the accompanying drawings, which illustrate one form of my invention:

Fig. 1 is a side elevation of the hook and eye members in the approximate relative position they must occupy to permit the hook to enter the eye.

Fig. 2 is a plan view of the hook and eye members separated.

Fig. 3 is a sectional view with the parts in the relative position shown by Fig. 1.

As illustrated, the hook and eye members are each formed of a single piece of wire, although this is not an essential feature of the invention, as said members could be made of sheet metal, for example. The hook consists of eyelets 10, a shank 11 coplanar with said eyelets, and a bill 12, which is formed by bending up the wire from the plane of the shank and then bending the wire downwardly, the hooked end of the bill thus formed extending preferably in a plane inclined to the plane of the shank.

The eye member comprises an eye 14 adapted to coact with the hook and a pair of eyelets 15 for attachment to a garment.

The eye 14 is of an elongated form preferably and has its major axis slightly greater than the width of the hook and has its minor axis preferably not much greater than the thickness of the wire composing the hook. It will be clear from this construction that in order to hook the bill 12 into the eye 14 it is necessary to bring these parts into a relative position substantially like that shown in Figs. 1 and 3. When the parts are brought into this position, however, no force is necessary to effect their full engagement, the eye sliding easily up the downwardly extending portion 13 and then around the bend and down the upwardly extending portion of the bill to its final position parallel with the hook. It will be noted that when the parts are fully engaged there is practically no chance that they will become disengaged, for to effect disengagement it is necessary to raise the eye bodily from the plane of the hook to the upper bend, then rotate it through an angle of about and finally slide it down the inclined extremity 13, a sequence of movements which could hardly occur accidentally.

Now having fully described my invention, what I claim as new and desire to secure by Letters Patent of the United States is A hook and eye fastener consisting of a hook member formed of a single piece of wire bent at its central portion and curved at its ends to form eyelets, the opposite portions of the wire extending from said eyelets in straight lines to form a shank and then extending upwardly from the plane of the shank and then bent and extending downwardly at an acute angle to said plane to form an overlying hooked bill, the end of which is spaced from the shank a distance substantially equal to the diameter of the wire forming the eye member, and an eye member located in one plane also formed of a single piece of wire which has its central portion bent to form an elongated eye, the major axis of which is slightly greater than the width of said bill and the minor axis slightly greater than the thickness of the wire composing said bill, the wire members extending from said eye and curved at their ends to form eyelets.

In testimony whereof I hereunto affix my signature.
