IMPROVEMENT'IN SNAP'HOOKS.

The Schedule referred to in these Letters Patent and 'making part of 4the same To Uall whom it may concern: p l Be it known that I, DAVID J. BLASIE, of Western, in thecounty of Oneida'and State of New York, have Hooks;and I do hereby declare .that-the following `is. a full, clear, and exact description thereof; which will enable others skilled infthe art lto make and use 'drawing forming` part of this specification.

` i i i. This invention relates to improvements inthe construction of snap-hooks, and` inode of attaching the reinsfthereto, and consists in making the shank of the invented a. new and useful Improvement ii1`Snap-` v the same, reference being had'to the accompanying` hook, which iisbroad' andiat, `and broader atthe endY than at the junction `witlia'ftlie hook, and providing al clasp correspondingto it, `for slipping on, inA the direction of the strain on `the rein, which clasp con-A fines thc end ofthe rein against the side ofthe shank i npourivets projecting froiniit, ,and also confines4 the snapspring .in away to admit of readily removing it and applying another, when broken or rendered useless for any cause.

The said improvedy mode of attachment obviatesthe `necessity `of the buckles now used, and makes a conncctiofn which is much heater, by reasonof having no lprojecting straps, Ste.' j, F'gure 1S is `a sectional elevation of `my improved snap; and the connection with the strap; i

view of the hookand spring; and i Figure 3 is a perspective view of the clasp.

Similar letters of 7A is thehook, and A B, the shank thereof.` c The latter is broad and iiat, beingbroader 'at the e'nd than atfthe junction \vith=the.11ock. v

. At or near the said junctionisa shoulder, 0,' agains which the endof the reinis toabut.4

The said shoulder is aboutl as high as thethickness of therein. Y Itis recessed to provide space 4for the refe-rence indicate corresponding` tlat snap-spriiigD, which is placed on the side of the shank, and extends from the end thereof to the pomt of the hookpassing through the said'recess.

E represents pins rising upjfromthe-iicc of the shank about as high as the 'thicknessdf the rein, to pass through holes in it when placed against the face of the saidshank, as shown 'in fig. Onefof ,thesej pins passes through the spring D near Ithe end.V i

,F is the clasp. It is made of sheetmetal, locutor stamped into the requisite shape' to cover the front side and edges of the strap, also the edges ofthe 'shank B, and having iianges Gr, to tit in the groove H, at the back offthe shank,near the edges; also, the projection Lto-be bent down overthe ends'or corners ofthe shank, to permitfthe said clasp, which, beingtapered` to correspond'with theform of the shank, is applied after 'the spring and strap are put inl place, by slipping over the shank from the smallest end4 toward the widest. ,y Y

The walls K'of the clasp are also madewidest -at the end which is applied tothe shank first, so that` it clasps the leather strap to the shank closer the more.

-it is forced on. i

It will be seen/that this constructionis cheaper and simpler than that now in use; also, that-,it is, much neatel', and that/it can be taken apart at any time and a new spring applied when required.

`The shank of the hook and the rivets or studs may. be formedl at one blow of a drop-press, and the clasp may be made by stamping machinery,"very cheaply, Having thus described my invention, I claim as new aud'desire to secure by Letters APatent- A .The combination with the hook, provided withthe shank B andrivetszE, of thev spring D and clasp F, `all substantially as specified.
