LOGGING-HOOK.

Specification of Letters Patent.

Patented Mar. 23, 1920.

Application filed April 1'7, 1919. Serial No. 290,718.

To all whom it may concern Be it known that I, 'WALTER BAs onn, a subject of the King of Great Britaln, and a resident of the town of Mission Clty, 1n the Province of British Columbia, Canada, have invented certain new and useful Improvements in Logging-Hooks, of whlch the following is a specification.

My invention relates to improvements in logging hooks, and the object of my invention is to provide a hook adapted for use 111 logging operations or other similar work by w the use of which the load is securely held to the hauling line, while at the same time Y connection and disconnection of the load line from the hook is effected with great ease and convenience.

I attain this object by the construction illustrated in the accompanying drawings 111 which- Figure 1 is a side view of the hook.

Fig. 2 is an edge view.

Fig. 3 is a fragmentary sectional view showing the locking arrangement.

Fig. 1 is a detail view of the locking member.

Similar figures of reference indicate sunllar parts throughout the several views.

The hook, indicated generally by the numeral 1, is formed as shown in Figs. 1 and :2, having the shank 2 connecting the hook hill 3 with the eyed end 41-, on which eyed end is swingably mounted a finger 5 the upper end of which is jawed as at 6 to engage the reduced upper end 7 of the shank, as shown, the finger being held in place by abolt or pin 8 which passes through the shackle 9, the jaws 6 and the eye 1. The lower end of the finger 5 is provided with a hole 10 in which, when the hook entrance is closed, the point 11 of the hook hill 3 1s e11- gaged to prevent side movement of the finger.

12 indicates a rectangular recess formed in one side of the upper end 7 of the shank, through the wall of which recess extends a hole 13, and mounted in the recess for sl1dable movement therein is a rectangular member 14 having a pin extension 15 adapted to extend slidably through the hole 13. Adj acent the inner end of the member 1 1 the pin is enlarged to fit the recess, as at 16, the enlarged portion forming a guide for the member 14 to prevent side movement. Mounted on the pin between the wall 17 of the recess and the portion 16'is a spring 18 normally intension and adapted to be com pressed by the act of pressing the member 14E inward, from which it will be seen that the member 14 operates similar to a push button, and as it projects from the side of the hook it may be pushed inwardly at will.

This button lt extends through a notch 19 in one of the jaws of the finger and on its upper edge it is notched as at 20 and 21, the side face of the notch 20 being normally on the inside of and engaging the finger jaw so that the button cannot be inadvertently displaced while the bottom face of the notch is, when the hook is closed, directly in alinement with the finger notch 19 which then straddles the top edge of the button so that the finger cannot be swung upwardly, as this notch is of less depth than the sides of the finger notch. On pushing the button inwardly, however the notch 21 is brought into alinement with the finger notch 19, and as notch 21 is deeper than the sides oi? notch 19 the finger may be swung upwardly to open the hook entrance 22, from which it will be seen that to permit swinging the finger up to open the hook all that is necessary is to push in the button 14 the required amount, the closing of the entrance being efiected by swinging the finger downwardly until the finger notch 19 registers with the recess 12, when the spring 18 will force the button outwardly so that the notch 19 will engage its top edge and prevent inadvertent unlocking of the finger.

From the foregoing it will be seenthat I have devised a simple andinexpensive hook which is of great utility and convenience in logging operations.

What I claim as my invention is:

1. In a hook, a finger having its upper end jawed and pivotally connected to the hook head and its free end resting on the hook bill so as to close the hook entrance, one of said jaws having a notch, and a pin mounted in the hook shank having its outer end onlarged and adapted to extend laterally to project through the jaw notch which straddles it to prevent upward movement of the finger, said enlarged end being adapted for inward lateral movement by manual operation so as to carry a notch with which it is provided into alinement with the jaw notch and permit upward movement of the finger. V

2. In a hook, a finger having its upper end jawed and pivotally connected to the vent outward movement of the pin and a notch outside the aw of greater depth than the lower edge of the jaw, the said enlarged end being adapted for inward lateral move ment by manual operation so as to carry said notch into alinement with the jaw notch and permit upward movement of the fin er.

Dated at Vancouver, B. (3., this 3rd ay of April, 1919.
