WVILLIAM BELLAIRS, OF MITCHELLVILLE, IOXVA.

SNAP-l-IOOK.

SPECIFICATION forming part of Letters Patent No. 279,4'77, dated June 12, 1883.

Application filed February 19, 1883. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM BELLAIRS, a citizen of the United States, residi ng at Mitchellville, in the county of Poll( and State of Iowa, have invented certain new and useful Improvements in Snap-Hooks, of which the following is a specification, reference being had therein to the aecompanying drawings.

My invention relates to certain new and useful improvements in snap-hooks, but more particularly to' improvenents on the patent granted to me by the United States Patent Office J une 5, 1866, No. 55,229, snap-hook.

The object of my invention is to construct a snap-hook that can be readily adjusted to the ring in the loridle-bit, neck-yoke, or pole-ch ain ring, and other like purposes, that is not liable to be detaehed by accident when in use, that willbe durable and eflicient, while the cost of Construction will be .much less than required for the production of the snap covered by my former patent above named.

Referring to 'the drawings, Fi gure 1 represents a perspective view 'of my improved snap,

showing the parts in place and the snap closed. Fig. 2 is a longitudinal seetional view, showing the inner and outer hook and spring. Eig. 3 is a detail View, showing the inner hook.

' Similar letters refer to similar parts throughout the drawings.

My device, when complete, is formed of an outer and inner hook, a spring and guide-pin,

and end loop.

The outer hook, A, is formed with an inwardl'y-turned lip, a and outward projections a', with an end loop, O, for the reception of a pol e-strap, halter-stem, or other devices whereon snaps are used. Hook A has a longitudinal recess or channel formed 011 its inner edges, and the outer end has a vertical slot, g, cut entirely through that portion of the hook, as shown in Fig. 2. The inner end of said recess or channel terninates in a square shoulder, h, against which one end of coiled spring f abuts, as shown in Fig. 2.

The inner hook, B, is formed somewhat similar in a part of its Construction to the outer hook, A. The outer end ofhook B is curvcd outward and inward to conform to the shape and size of the same part of hook A, and is provided with inward projections b and b', leaving a sufficient space between said projections for'the passage of a ring. An elongated space, e, is provided for the reception and play of the ring, the same as is produced by the Construction of the outer hook, A. The inner hook, B, is forned fiat, and has an eX- tension rearward, with a vertical projection, D, by which said hook B is retracted when desired to hook or unhook said snap. The under side of said extension is forned with a square shoulder, c, against which the outer end of spring f abuts, and by which said hook B is forced to its place inside of hook, A. An angular slot, d, is formed on or in the lower edge of hook B, its inner end terminating near shoulder c, through which passes stop-pin l, as shown in Fig. 2.

A coiled spring, f, is placed in a recess formed in the shank of hook A, the inner endof which rests against the shoulder 71, and the outer end against the shoulder c, as shown in Fig. 2.

In putting the parts together, the innerhook, B, is inserted by its inner end through slot g to near the place for the pivot-pin or stop-pin *1 when springf is placed in the recess formed in hook A. Then the hook B is pushed in until the stop-pin i can be pushed through slot (l, when the parts are secured in place.

The operation is as follows Then desired to hook the snap onto a ring, the thumb or finger of the operator is pressed against the projection D, when the innerhook is retracted, leaving an open space between the points a and As soon as the ring has passed into the space e the projection D is released, when the inner hook, B, is throwu out to 'its place against the stop-pin i by the coiled springf.

Having thus described my inventiou, what I claim, and desire to secure by Letters Patent, 1s--` i 1. A snap-hook'composed of an outer and inner hook, the inner hook sliding within the outer hook, as described, the outer hook havingan end loop for the reception of a strap er rope, said hook slotted through its outer end, and recessed as described, the inner hook sl otted and i'ormed as described, and adapted to work against a coiled spring located in the shank IOO of the outer hook, substmtlly as and 'for the In. tesbnony whereof I affix my signature in purpose set fo'th; presence of two witnesses. 2.
