Specification of Letters Patent.

Patented May 28, 1907.

Application filed November 9, 1906. Serial No. 342,681.

To (LZZ whom it may concern:

Be it known that I, THOMAS WATSON, a citizen of the United States, residing at Evanston, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Snap-Hooks, of which the followinglfiis Ispecification, referenceiii'being had therein to the accompanying drawing.

This invention relates to lmpro vements in snap hooks.

The object of the invention is to improve the construction of snap hooks, and to provide a simple and comparatively inexpensive device, whichigis etficient in operation, and durable in structure.

IVith this and other objects in View, the invention consists ofcertain novel constructions, combinations, and arrangements of parts, as will be hereinafter fully described and claimed.

In the drawing: Figure 1 is a perspective view of a pair of my devices, constructed in accordance with the present invention, attached to a swingletree. Fig. 2 is an en larged, inverted, perspective view of a snap hook constructed in accordance with the present invention, and having the springpressed catch removed. Fig. 3 is a longitudinal, sectional view of the snap hook, constructed in accordance with the present invention. Fig. 4 is a perspective view of the slidable catch.

Referring to the drawings, 1 designates the body of the snap hook. Integral with the body 1, is a stem 2, which stem is apertured at 3. In Fig. 1, I have shown a plurality of my snap hooks attached to a swingle-tree 4, preferably by positioning a link 5 in the apertures 3 of the stem 2; the links 5 being attached by any suitable means to the swingletree 4. In the sides 6 of the body 1, there are formed longitudinally extending, elongated slots 7. A compartment or pocket 8 is formed in the body 1 between the sides 6, 6. Integral with the body 1, are parallel arms 9, which constitute a bifurcated end of the snap hook. A tongue is pivotally mounted, as at 11, between the arms 9. The tongue 10 comprises a primary hook 11 and an auxiliary hook 12. The primary hook 11 is provided near its outer end with a notch 13. Both the primary and auxiliary hooks 11 and 12, respectively, are curved throughout their length. A block 14, preferably substantially V-shaped, is positioned between the arms 9, and constitutes a stop for limiting downward movement of the pivoted tongue 10. The primary hook 11 engages one of the edges or sides of the block 14, while the auxiliary hook 12 engages an opposite edge or side of said block. 10 is in its closed position, as in Figs. 1 and 3, the tongue and arms 9 constitute a link, within which link any suitable attaching member may be secured. When the tongue 10 is removed from the position illustrated in Fig. 3 to an opened position, Fig. 2, it will be seen that if an attaching member was in engagement with the tongue positioned between the primary and auxiliary hooks 11 and 12, respectively, the auxiliary hook 12 would assist in lifting the attaching member, and as the tongue swung upon its pivot 11, the attaching member would be permitted to ride over the primary hook 11, and consequently, be removed off of the tongue 10. It will, therefore, be seen that the tongue is substantially C-shaped, and is pivoted intermediate its ends, preferably, near its center. When the substantially C-shaped tongue 10 is in its closed position, the block or stop 14 will fit between a portion of the hooks 11 and 12.

A slidable catch 15 is assembled with the body. The catch 15 comprises a base-plate 16 provided with parallel, vertical, integral lugs 17, 17. The lugs 17 are secured near the forward end of the base-plate 16, thereby leaving its rear portion 16 unobstructed, so

that when the catch is moved to its farthest 2, said rear porposition toward the stem tion 16 will extend beyond the body, and can be easily grasped by the operator manipulating the slidable catch. The vertical hook 18 of the catch 15 is preferably integral with the base-plate 16, and positioned between the lugs 17. A horizontal pin 19 extends thiough lugs 20 and hook 18. When the catch 15 is in its normal position upon the body 1, the lugs 17 will be positioned against and upon the outside of the sides-6, and the pin or bolt 19 will extend through the elongated apertures 6, thereby fastening the slidable catch upon the body. Positioned within the pocket or compartment 8 of the body 1 and pressing against the hook 18 is a yieldable member, as for instance, spring 21. The spring 21 normally exerts outward pressure upon the slidable catch, thereby holding hook 18 at one end of the When the tongue pocket or compartment 8, whereby it is always in position to retain the tongue 10 in aclosed posit-ion, as in Fig. 3. It will be obvious that the hook 18 is adapted to engage the notch The hook 18 is beveled at 18 to facilitate the locking of the tongue 10 in its closed position. The forward end of the base-plate 16 of the spring-pressed, slidable catch 15 is adapted to engage spurs or stops 16 formed upon the sides 6 of the body 1. These spurs or stops 16 limit forward movement of the catch 15. The compartment 8 is open at its bottom and the catch 15 constitutes closing means therefor, for preventing the entrance of foreign substances.

What I claim is:

1. In a snap hook, the combination of a body, a substantially V-shaped block carried by said body, a movable tongue provided with curved hooks, the hooks of said tongue adapted to be positioned upon and engage opposite sides of said block for limiting movement of the tongue, and means for locking said tongue upon said block.
