MATTHEW ADAM, OF PHILADELPHIA, PENNSYLVANIA,

HOOK AND EVYE.

SPECIFICATION forming part of Letters Patent No. 599,758, dated March 1, 1898.

Application filedMay 27, 1897. Serial No- 638,361. (No model.)

-- have invented a certain new and useful Improvement in Garment Hooks and Eyes, whereof the following is a specification, reference'being had to the accompanying drawlugs.

In said drawings, Figure 1 represents a top or plan view of the hook and eye in engagement, Fig. 2 being a view of the same in side elevation.

The object of my invention is to provide a hook and eye which shall admit of being readily fastened or unfastened when force is intentionally applied thereto and which shall resist accidental movements tending to unhook the eye, and the construction being such as to present no projecting sharp points or ends of Wire, and the parts all lying substantially fiat when engaged.

Referring to the drawings, A represents the hook, and B the eye, each of which is provided with the usual thread-eyes a a and b I), respectively. The sides of what would in an ordinary hook be termed the shank of the hook are bowed laterally outward, as indicated at C G, forming curved springs, and as they approach the bight or bend D are curved rearwardly-that is, toward the body of the person-as seen most clearly in Fig. 2.

Intermediate between the sides 0 G is the part E, which by analogy would be termed the bill, but which differs from the usual bill of a hook in that in the present instance it lies substantially flush with the sides, instead of rising above the same, and is bent in correspondence with the rearward bending of that portion of the shank which is proximate to the bight. The sides of the bill itself arebowed or arched outwardly, as indicated at e e, forming a double incline on each side with a somewhat flat angle, so as to afford an easy riding-surface for the engaging portion of the eye. At the base of the bill, where the sides merge into the bight D, they are separated by a small interspace.

The eye'as a whole is indicated at B, the engaging portion or loop thereof F being situated at the end of the two shanks f f which diverge laterally therefrom. The spread of these shanks at the region of the thread-eyes gives a comparatively wide base for attachment,-and thus insures a firm support. The loop F is also curved rearwardly in a manner substantially corresponding with the curve of the hook near the bight D, the bending of the eye being preferably a trifle more prolonged than that of the hook and the curve near the end beak slightly more abrupt where great accuracy of adjustment is desired. By thus correspondingly curving the bight ends of the hook and eye, respectively, the bight of the eye will pass into contact with the two bights of the hook and pull thereon, and the curva ture is such that when thus engaged the body will not weaken the hook and eye, as would bends at right angles. Moreover, the rearward curvature of the eye permits it to enter the space within the bow C C in front of the bill E, where it may be readily engaged with the bill.

The intermediate space between the proximate faces f f of the loop F is less than the distance between the outside portions of the sides 6 e of the bill, so that in the act of hooking or unhooking the parts must yield. This yielding may be accomplished through the bending together of the two sides of the bill alone, orit may be aided by the slight outward bending of the two sides of the loop; but in either case the movemen't,though quite minute, is an entirely positive and appreciable one, so that a distinct though slight effort is required to either hook or unhook the loop.

The bill E terminates within the bow G C, so as not tooverlie the fabric where the cars a a are stitched, and thus the eye F may be readily engaged with the bill without the necessity of raising the bill into a higher plane than the bow, as would be necessary if the bill should.v be extended back to the stitchingpoints a a.

It will be observed that the line of the wire required for hooking or unhooking and at the same time obviate the liability to permanent ioo billis not new, and I do not broadly claim such method of construction.

I claim The combination with the hook having the sides of its shank beyond its stitching portions bowed outwardly, and a bill having double inclines on its sides and lying fl ush within the bowed portion; the bight ends of the hook being curved rearwardly, of an eye having a loop of less diameter than the maximum width of the bill and curved rearwardly at its closed end to correspond with the curvature of the bights of the hook, thereby permitting it to engage and pull on the said bights, and said curved portions also permitting the bodies of the hook and eye to lie in the same longitudinal plane; substantially as described.

MATTHE\V ADAM.
