SNAP-HOOK- SPECIFIGATION forming part of Letters Patent No. 762,097, dated June '7, 1904. Application filed June 17, 1903. Renewed April lB, 190% Serial No. 203,805. (No model) T at whom it may concern:

Be it known that I, SAMUEL SMITH, a citizen of the United States, and a resident of Weede, in the county of Fergus and State of Montana,

5 have invented anew and Improved Snap-Hook,

of which the following is a full, clear, and exact description.

c This invention relates to snap-hooks; and it consists in certain parts and details and com- IO binations thereof hereinafter particularly described and claimed. 7

One of the principal objects of my invention is to provide a snap-hook which is simple in construction and organization as Well as easy to operate and not liable to get out of order or become clogged up in use, besides being strong and durable and composed of few parts.

7 A further object of the invention is to provide a device of this kind which is effective and reliable in use and one also which is comparatively inexpensive to manufacture and possesses the capacity for long and repeated service. The above and additional objects are at tained by means substantially such as are illustrated in the accompanying drawings, in which similar characters of reference indicated corresponding parts. in all the figures. Figure 1 is a side view of one form of my improved snap-hook. Fig. 2 is a part longitudinal sectional view of the construction shown in Fig. 1, illustrating the operation of the parts. Fig. 3 is a view similar to Fig. 1, 3 5 representing a slightly-different form of my improvements; and Fig. 4 is a view similar to Fig. 3, partly broken away and vin section, representing more clearly the construction and operation of the parts of this latter form of the snap-hook.

Before proceeding with a more detailed description it may be stated that in each of the forms of my improvements herein shown I employ a snap-hook comprising an ordinary shank and bill, and cooperating with the end of the bill is a movable yoke which is normally maintained in closed relation with said bill, thus preventing disengagement of the v spect to one end of the shank, as shown.

hook from any device to which the same may be attached for fastening or similar purposes. 5 I employ a specially-constructed thumb-plate or lever for operating the yoke to enable the application and release of the hook in the uses to which it may be applied, said lever securely holding a part of the yoke in contact with the end of the bill, and while I have herein illustrated my improvements in certain preferred embodiments it will be understood, of course, that I amnot limited to the precise details thereof in practice, since imma- 6o terial changes therein may be resorted to coming within the scope of my invention.

Specific reference being had to the drawings by the designating characters thereon, 1 represents the shank of the snap-hook, and 2 the bill thereof, which is bent or curved with re- In the embodiment of my improvements shown in Figs. 1 and .2 vI employ a yoke 3, having duplicatecheek-pieces 4, which are a distance apart substantially equaling the Width of the shank 1 at the part thereof to which the yoke is attached, said yoke being closed at the top between the cheek-pieces, as shown at 4c, and said cheek-pieces being pivoted to the shank at 5,. it being. observed that for the purpose of symmetry the upper surface of the yoke is practically even with the corresponding surface portion of the bill 2, the inner edge portion 6 of said yoke normally overlapping the end portion of the bill, asshown, and prefer.- ably abutting against'a shoulder 7 on the upper part of said bill. At the outer upper part of the yoke the said cheek-pieces 4L are connected by means of a small rod 8, and preferably the edge of the closing portion 4 adjacent to said rod is bent downwardly at 9 for the purpose presently explained. Secured to the shank at 10, by means of a rivet or otherwise, is one end of a spring thumb-plate or 9 lever 11, which is bent inwardly at 12 near its free end to form a shoulder, as shown, the said free end of this lever normally bearing beneath the end portion of the hill 2 withina notch 13, formed in the latter. Normally the under side of the shoulder 12 of the lever is directly above the said rod 8, connecting the cheek-pieces, and to operate this form of my improved snap-hook it is simply necessary to depress the said spring-lever to the position indicated in dotted lines, Fig. 2, which act causes the shoulder 12 to ride upon said rod 8 in a -manner to rock the yoke backwardly, thereby bringing such yoke to open relation with the bill of the hook, as shown, and for a purpose well understood. On releasing the said lever the yoke is reversely operated, as is apparent, due to the resilient action of the lever, and in this way the yoke is again carried or rocked to closed relation with the end of the bill. In the normal position of the parts the yoke is prevented from accidentally rocking outwardly by means of the bent edge 9 thereof in this instance the cheek-pieces 1A of the rocking yoke are pivoted at 16 to the upper ends 'of stationary brackets 17, secured at 18 to opposite sides of the said shank 1. Also [in thi'sfinstance the spring-lever 19 is minus the shoulder 12, being simply struck on a slight uniform curve throughout its length, as shown, .the lower surface of the free portion of this lever working over the rod 20, connecting the cheek-pieces, as in the first con- I struction explained, the free end of the lever bearing beneath the free end portion of the bill 2 within a similar recess 22 therefor, also as before. To cause the yoke to be rocked to carry the same to open relation with the bill, said lever 19 is simply depressed to the position shown in dotted lines, Fig. 4.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent 1. A snap-hook comprising a shank having a curved bill, a pivoted yoke normally occupying a closed relation with the bill, and a spring-lever having one end secured to the shank and its free end extending into engagement with the bill of the shank, the lever intermediate of its ends loosely engaging the yoke.

2. A snap-hook constructed with a shank and a curved bill, a yoke having cheek-pieces pivoted to the shank, and provided with a rod connecting said pieces near the outer edges thereof, and a spring-lever secured at one end to the shank and having a portion thereof passing over said rod, the free end of this lever normally abutting beneath the free end portion of the bill.

3. A snap-hook constructed with a shank and a curved bill, and comprising a pivoted yoke closed by a top portion, and having cheek-pieces pivoted to the shank, and also provided with a rod connecting said pieces near the outer edges thereof; and a springlever secured at one end to the shank, and passing over said rod, and engaging beneath the end of the bill, said top portion of the yoke being bent inwardly at the outer edge thereof, and said lever being bent to'form a shoulder.

4:. A snap-hook comprising a shank having a curved bill, a pivoted yoke, and a springlever having one end secured to the shankand its other end formed with a shoulder and extending into the yoke through an opening therein.

In testimony whereofl have signed my name to this specification in the presence of two subscribing witnesses.
