SNAP-HOOK.

SPECIFICATION forming'part of Letters Patent No. 376,040, dated January 3, 1888.

Application filed Oclober`24, 1887. Serial No. 253,242. (No model.)

To all whom it may concern:

Be it known that LGEORGE D. MosHER, of

Birmingham, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvementsin Snap-Hooks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which i'orIn part of this specifica'- tion.

My invention relates to an improvement in snap-hooks; and it consists in the combination of the body of the hook, having a recess made in its shank, and two sets of projections which extend from opposite sides 'ot the 4recess,with arbent at spring which is caught between the two sets of projections and held in position thereby, as will be more fully described hereinafter. Y

The object of my invention is to provide a snap-hook in which the spring is made to close the entrance of the hook, and in which but two parts are used.

W Figure 1 is a perspective of the body ofthe hook before the spring is applied thereto.

Fig. 2 is a vertical longitudinal section taken through the finished hook.

A represents the body of the hook, which is made of any malleable metal, and which when first cast has the point B of the hook turned at an angle to thebody or shank, as shown in Fig. 1, so as to allow they spring to be freely inserted into position. In that side of the body or shank which is next to the hook is formed a recess, C, and projecting from opposite sides of this recess are the two sets of pro-l jections, I J, between which the spring is held. In casting'the body A this recess C is left'open at its top for the free insertion of the spring,

and then after the spring is placed in position a sufficient amount of pressure is applied to opposite sides of the body or shank toclose the sides of the recess against the edges of the spring, so that it will be held in position betweenl the two sets of projections. The two outer projections catch against the outer bent portion of the spring H, while the two inner ones, J, catch againstvits inner side, and thus the spring is held at its bent port-ion, so that it can neither move forward nor back. This spring H consists of a flat `plate which is bent, so that its ends will be of unequal length, the short end being made to rest in the bottom of the recess C, while the longer end catches against the inner side of the hook after it has been bent into position, as shown in Fig. 2.

by closing the sides of the recess against its edges, pressure is applied to the pointv,` so as to straighten it into a linewith the spring.

It will be seen that this snap-hook consists of only the body and a fiat spring, and that the spring is held rigidly in position by the two sets of projections which catch over opposite edges.

Having' thus described my invention, I claim- In a snap-hook, the combination ofthe body A, having the recess C formed therein, and lateral projections extendingfrom the side or sides oi' the recess, with the bent spring H, which is placed in the recess and held in position by having its bent portion confined between the projections, substantially as shown.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE D. MOSHER.
