IMPROVEMENT IN SNAP-HOOKS.

Specification forming part of Letters Patent No.'122,127,dated December A26, 1871.

To all persons to whom these presents may c0me:

Be it known that I, LEWIS MORSE, of Attleborough, of the county of Bristol and State of Massachusetts, have invented an Improved Snap Hook; and do hereby declare the same to be fully described in the following specih'cation and represented in the accompanying drawings, of which- Figure l is a side view, and Fig. 2 a longitudinal section of such snap-hook. Fig. 3 is a representation of one-halfoi' the snap-hook, hanger, and body, as struck from a plate of metal by means of dies.

The common snap-hook, as ordinarily made, has its tongue constructed separately from the body, and connected thereto by a hinge, and resting against a spring entirely separate from the hinge, the spring being solnetimes placed in the shank ot' the body and at other times within the bow or hook. One distinguishing feature ofdifference between my snap-hook and others above referred to, asusually made, is that the tongue is connected to the body by the spring, which, by its arrangement, answers the purposes of a hinge for the tongue, and a spring for closing it against the oblique end of the hook part of the body. Another distinguishing feature is that the body and tongue are iirst struck together from two thin plates of metal, each partso struck having the torni shown in Fig. 3, wherein the hook and tongueparts are in the forni of a bow or yoke chan' neled throughout, and connected to the shank, which is also channeled. Two of the said parts, shown in Fig. 3, are laid and soldered together at their edges, after which the tongue part is to be sawed or cut from the shank and hook portions, and reconnected with the shank by means of a short steel spring extended into both, and

soldered or fastened to them.

In the drawings, a denotes the hook; b, the tongue; c, the shank; d, the spring; and e the swivel eye, the. latter heilig iixed onthe journal r point of the shank. The spring d, by being entirely inclosed within the tongue and shank, is not only protected from injury and loss, but serves the double purpose of a hinge and a spring.

I make no claim to any thing, combination, or arrangement of parts, as shown or described in the United States Patent No. 55,563, the spring ot' my improved snap-hook being arranged dii'- ferently, relatively, to the tongue and body from Vanything represented in such patent.

hook as made with its tongue and body composed ot' two bows struck or formed from plate metal and soldered together, and the tongue next cut or separated from the body, and next reconnected therewith by a spring arranged `in and xed to the two, as described, whereby the spring is made to serve a double purpose, as explained.

Witnesses: LEWIS MORSE.
