HOOK.

SPECIFICATION forming part of Letters Patent N 0, 683,475, dated October 1, 1901.

Application filed December 28 1900. Serial No. 41,435. (No model.)

To aZZ whom. it may concern.-

Be it known that I, HENRY O. MASTERS, a subject of the Queen of Great Britain, residing at Hamilton, Bermuda, have invented a certain new and usefulImprovementin Hooks, of which the following is a specification.

My invention relates to an improvement in hooks in which the standing part of the hook is mounted in a swivel while the point is hinged to the standing part and adapted t be locked in a lug on the swivel.

The object of my improvement is to provide a hook which may be readily and positively locked when desired without danger of disengagement, while at the same time great additional strength is given to the structure. Iattain these objects by the mechanism illustrated in the drawings, in which-- Figure 1 represents a front elevation of my improved hook, and Fig. 2 a top view of the same.

In the drawings, as shown, 1 is the swivel, having a perforated lug 2 for engaging the pointed member of the hook.

3 is the standing part of the hook, and is held in the swivel by head 4 or other appropriate means.

5 is the hinge or knuckle on which the pointedmember 6 of the hook rocks.

7 represents means for locking the pointed member 6 in the lug 2, so that no accidental upward thrust will disengage the same.

To disengage the point from the lug, it is first necessary to open the point by displacing means 7. Then an upward thrust Will cause the point to pass out of the lug, while at the same time it rocks away from the same on knuckle 5. The book may then be turned in any direction permitted by the swivel, and is reengaged with the lug by bringing the point over the perforation in the lug and pulling downward. It is thus seen that not only is the point locked to the swivel, but the hook is held rigidly in the same, while the strain on the hook is more evenly distributed than heretofore.

It is obvious that different means may be employed to lock the point and that the knuckle may be done away with if sufficient play is allowed the standing part of the hook in the swivel.

I do not wish to restrict myself to the details shown; but

What I desire to secure and claim by Letters Patent of the United States is- 1. The combination of a swivel having a perforated lug integral therewith,with a hook depending from the swivel, said hook being provided with means adapted to detachably engage the lug, substantially as set forth.

2. The combination of a swivel having a perforated lug integral therewith, with a hook depending from the swivel, said hook having a rocking member adapted to detachably engage the lug, substantially as set forth.

3. The combination of a swivel having a perforated lug integral therewith, with ahook depending from the swivel, said hook having
