HOOK.
Specification of Letters Patent. Patented Aug. 21, 1917.
Application filed April 14, 1917. Serial No. 162,169.
'1 0 all whom it may concern:
Be it known that I, ERICK ERICKSEN, a citizen of the United States, and a resident of Astoria, in the county of Clatsop and State of Oregon, have made certain new and useful Improvements in Hooks, of which the following is a specification.
My invention is an improvement in hooks,
and has for its object to provide a device of the character specified, arranged to permit the hook to be easily and quickly connected, and to positively prevent accidental detachment of the same.
In the drawings- Figure 1 is a side view of the improved hook.
Fig. 2 is a vertical section, and
Fig. 8 is a top plan view.
In the present embodiment of the invention, the hook comprises a body 1 anda bill 2, and a clip or clevis 3 is connected with the body by means of a bolt and nut 4E.
The body of the hook at the end remote from the bill has a slot 5, whose long axis extends toward the bill of the hook, and the bolt is passed through this slot and registering openings in the clip. Thus the clip'and the hook may move toward and from each other within limits.
A keeper 6 is provided, the keeper being notched or recessed at one end, as indicated at 7, to receive the body, and the said keeper is provided with a-transverse opening intersecting the notch, for receiving the bolt which connects the clip to the body of the hook. Thus the keeper is pivoted to the body by the bolt.
At its opposite end, the keeper has a longitudinal extending slot or passage 8 of a width to receive the bill of the hook and the said bill is provided with a transverse rib or shoulder 9, with which the end of the slot or passage remote from the bolt 4 is adapted to engage as shown more particularly in Fig. 2.
This slot or passage 8 is of greater length than the distance between the shoulder 9 and the end of the bill, as shown in Fig.
and the hook may be moved toward the inner end of the passage 8 todisengage the shoulder 9 from the outer end of the slot or passage by reason of the slot 5. A locking bar 10.is mounted to slide in a. recess 11 in the keeper 6, and a spring 12 arranged between the bottom of the recess and the bar normally presses the bar outward into the passage 8. This outward movement is limited by means of a pin 13 extending transversely of the recess, and engaging a slot 1 1 in the bar. WVhen the keeper is engaged with the bill of the hook, as shown in Fig. 2, the locking bar is pressed against the bill of the hook to prevent accidental displacement of the keeper from the rib 9.
To disengage the hook and keeper, it is only necessary to press the hook toward the keeper. This movement forces the bar 10 into the recess and permits the shoulder 9 to be disengaged from the slot or passage 8.
The greater the stress on the hook, the more tightly the shoulder 9 is forced against the slot or passage 8, and the hook 1 must be moved toward. the clip to disengage the keeper.
I claim:
A hook comprising a body and a bill, a keeper pivoted to the body of the hook at the end remote from the bill with a lost mo tion connection for permitting the keeper and the hook to move longitudinally with respect to each other, the bill of the hook having a transverse rib at the side adjacent to the keeper, and the keeper having a slot or passage for receiving the bill, the outer end of the slot or passage engaging the rib to lock the keeper in place, and a springactuated locking bar in connection with the keeper and engaging the end of the bill of the hook for preventing inward movement ofthe hook with respect to the keeper under normal conditions.
