CHARLES H. MILLER, 0F. BUFFALO, NEWpYoR'K, Letters .Patent No. 71,201, dated November 19,1867.

IMPROVBD SNAP-HOOK,

TO ALL WHOM IT MAY CONCERNE4 Be it known that I, CHARLES H. MILLER, of thecity ot Bualo, county of. Erie, and State`of- New York, have invented a certain new and improved Snap-Hook; and I do hereby declarcythat the following is a full, clear, and exact description'of the construction `and operation thereof, refereucebeing had tothe accompanying drawings, making a part of this specitication,in which'-' I Figure I is a side elevation of said snap-hook.

Figure II is a front elevation of same; and

Figure III is a front vi-ew' of the tongue bef'ore its connection with the hook.

invention consists in` making the joint of the snap-tongue with thehookY by a special formation and connection of the parts, as hereinafter described. 1

Letters of like kind and name refer to like parts in each of the figures.

A represents the hook proper, and B the snap-tongue, hinged to the shank of, and closing against, the point of the hook. The loop by which the hook is attached to the rein or strap is cast in one piece with the tongue, instead of' with the hook, as has'heretofore been the case. The intersection of the loop with the tongue is made to form a crotch, asv shown at b2, Fig. III, with projecting tents, b3, cast on each side thereof, which crotch receives the eye a.1 cast on the shank of the hook, andthe tents 63, entering said eye, form the joint or hinge of the tongue with the shank. The loop is ea-st in au expanded form, asshown in Fig. III, leaving a. space between the teats equal to the thickness of the eye-a1, so that, in bringing the two parts together,lthe eye may be entered betweenthe teats, when, by compressing th sides of the loop, (either by a smart blow with the hammer or by pinching in visejaws,) the teats will enter the eye, and a complete and perfect Vjoint be formed.

By forming the loop on the tongue, instead of on the hook, the casting of both yparts ismuch'sirnplied, for the reason that both parts will readily drawv from the sand, and no cores" are required. This manner of joining the tongue t-o the hook is believed to be the simplest, strongest,aud cheapest yet devised for that purpose. The s hank of the hook being extended, as shown at a2', forms, with `the loop, a. buckle, and, in connection with the loop c in the stra-p or rein to which it connects, causes a strain on'the rein or strap to close and hold the snap-tongue against the joint of the hook, thus operating the snap-tongue as rebuired without `the aid of a'spring.

Having thus described my invention, what I'claim, and desire to secure by Letters Patent, is-' Hinging the snap-tongue to the hook in the manner substantially as herein described.
