TO ANNIE M. SARUJ., 'O F NORTH VANCOUVER, c ivAnA.

. SAFETY-Hook;

.citizen of the Dominion of Canada, residing at North Vancouver, in the Province of British Columbia, Canada, have invented certain new and useful Improvements in Safety-Hooks, of which the following is a specification.

This invention relates to a closed hook or link for connecting wire ropes together or for connecting other devices to wire ropes, the object being to provide a closable hook, any pull imposed on which will tend to maintain the closure, and one that is free from projections calculated to catch or entangle on obstructions when drawn through the bush.

The device is fully set forth in the following specification, reference being made to the drawings by which it is accompanied, in which:

Figure l is a side elevation of the link with the closure in the open position.

Fig. 2 is a top plan view of-the hook. Fig. 3 is a section, on an enlarged scale, of the end of the hook'closure showing the latch.

In these drawings 2 represents the hook, the shank of which is bent round, as at 3, to oppose the point of the hook and leave'a space 4 for the introduction of the rope or sling which it maybe desired to connect.

P1votally mounted on a pin in the end of 3 is a closing member 5, the free end ofwhich is beveled, as at 6, to fit a corresponding bevel on the point of the hook against which it abuts, and the contacting faces of hook and closure are tongued and grooved together to prevent lateral displacement.

The closing member 5 has a portion 7 which projects squarely across the link so formed, and is apertured to receive the link or eye splice of the wire rope to which it is permanently connected.

The member 5 is retained in the closed position by a latch bolt 10 which is endwise movable in a socket provided for it adjacent the inner edge of the free end of 5. The latch bolt 10 is limited in its out;

' ward movement by a pin 11 which is secured in the bolt l0 and passes through an elon gated slot 13 in the adjacent edge of the closing member 5 to slightly project and form a finger engagement, by which the latch bolt may be withdrawn against the resistance of a spring 12 which normally Specification of Letters Patent.

the tongue ofth h k; v

.The' line to-which the-hook -is relatively permanently fastened, is connected at 7 to the inner end of the closing member 5, and tension on that line will thus tend to hold the point of that member closed on the hook point, in which closed position it is latched by the bolt 10 engaging the inner end 14 of the tongue.

It forms, therefore, a, safety hook retaining any rope or sling that may be intro-, duced through the opening 4, and at the same time it is free from any projection likely to catch or entangle in brush or roots when being drawn through the bush.

Havin now particularly described my invention, hereby declare that what I claim as new and desire to be protected in by Letters Patent, is:

1. A safety hook, the shank of which is recurved toward the point of the hook, a member pivotally mounted in the recurved end of theshank and adapted to close against the end of the hook and aline there with, said member having a projection within the recurved shank to whicha line is connected, the tension of whichline tends to hold the closing member in the closed position.

holds it at the outer limit of its movement. I -The' outer end ofthe latch bolt 10 engages 'a shoulder 14: 'formed on' 'the inner'end of member pivotally mounted in the recurved end of the shank and adapted to close against the end of the hook and aline there with, said member having a projection within the recurved shank to which a line is connected, thetension of which line tends to hold the closing member in the closed position, the point of the hook being angularly beveled to form a stop for the-corresponding beveled end of the closing member.

3. A safety hook, the shank of which is recurved toward the point of the hook, a member pivotally mounted in the recurved end of the shank and adapted to close against the end of the hook and aline'therewith, said member having a projection within the recurved shank to which a line is connected, the tension of which line tends to hold the closing member in the closed position, the point of the hook being angularly beveled to form a stop for the correspond-.

ing beveled end of the closing member, the beveled end of the hook having a tongue projecting from the mid-thickness of the hook, the point of the closing member having a corresponding groove to receive the" hook, the polnt of the closing member hav tongue When the hook is closed.

4. A safety hook, the shank of which is "recurved toward the point of the hook, a

member pivotally mounted in-therecurved end of the shank and adapted to close against the end of the hook and aline therewlth, said member having a projection Within the recurved shank to which a line is connected, the tension of which line tends to hold the closing member in the closed posibeveled to form a stop for the corresponding beveled end of the closing member, the

beveled end of the hook having a tongue projecting from the mid-thickness of the ing a corresponding groove to receive the tongue when the hook is closed, the closing member having 'an endwise movable latch to engage the inner end of the tongue of the hook point and retain the closed member in the closed position. i V

Intestimony whereof I aflix my signature.
