HOISTING HOOK.

1,386,583. Application filed April 3.
To all whomit may concern:
' Be it known that I, JOHN PA'rnnsoN, J r., a citlzen of the United States, and resident of Edlnburg,
in the county of lValsh and State of North Dakota, have invented certain new and useful Improvements in Hoist- "111g Hooks,
of which the following is a specification.
My present invention relates to a selfreleasing hook, and particularly to a device of this character intended to be used at the end of a cable or chain of a hoist, as
for instance on life boats, with a railroad wrecker, and in other like connections.
The principalobject of my'invention is to provide a hook of this character which will ecaught within-a ring and which will-hold as long as the weight draws thereon, the
l structure of the hook being such that when the'pull is releasedby slacking ofthe cable or chain, the hook will automatically move to a position in which it is released.
Another object is to so construct the .hook parts thereofswing the bill of the hooka line corresponding tion in which it might rengage or again catch within the ring from which it 1s to release.
Yet' another.object.is to provide a structurein whichithe hookis carried by a friction roller, thus insuring easy movement of the same, and whichhook structure will not become fouled with guy cables orthef-like,
after it has been released from the part or structure which has-been hoisted or moved.
Further objects of my invention will appear in the following detailed description, taken in connection with the accompanying drawing, forming a part of this specification, and in which drawing:
Figure 1 is a view in elevation of a hook constructed after the manner of my invention and showing the same swung to a hoisting position.
Fig. 2 is an elevational view illustrating the hook in its other extreme position, and with parts broken away and illustrated in sections to more clearly disclose the structure and arrangement of the parts.
Fig. 3 is a sectional view taken transversely throu h the hook member and in part through aie member by which the hook is carried.
Specification of'Le'tters Patent,
ber .A
Patented Aug. 2, 1921. 1918. Serial No. 226,517.
In the drawing, where similar characters refer to similar parts throughout the views, A designates the hook member which is carr1ed by thesupporting member B, this supporting member having a ring C passed through an eye thereof for securement of the hoisting chain or cable D.
- The-hook member A is made up substantially in the form of an elongated link at one side, one end of which forms the bill 4 the hook portion proper. The hill 4 is preferably tapered so that it may be more readily caught through a ring or the like,
' and will not offer obstruction when being Withdrawn therefrom, and at its remaining end the member A has an enlargement or weight portion 5. This enlargement at 5 is preferably extended as shown in the drawing, so that a great'portion of the weight thereof is thrown outside of the "link form of the member to one side of its major axis; A curved slot 6 is formed transversely through the member A in the middle portion thereof, opposite to the hook proper and the supporting member B is bifurcated at 7 to receive this slotted portion of the hook mema horizontal pivot 8 being secured across the bifurcated end of the member B and .received through the slot 6. To relieve friction of the member A when the same swings about the pivot 8, a friction roller 9 is revolubly mounted thereon, it of course being understood that this friction roller is given a loose fit withinthe-slot 6.
The supporting member 13 has an eye 10 at the upper end thereof through which the ring G isreceived, and as the'hoisting chain or cable Dis secured within this ring C,-the supporting member is suspended with the bifurcated end thereof depending downwardly. The member A is so formed that when the bill 4 of the hook portion proper thereof is caught through a ring 11, under the hail of a bucket, or through or around some. other like portion, the lower portion of the link form will be directly vertically below the pivot 8, and the parts will carry substantially as shown in Fig. 1. When the part carried by the hook is brought to the desired position and comes to rest, the chain or cable D will be slackened, and in consequence the pulling strain between the pivot 8 and the looped end of the hook member A adjacent the bill l will be released. The enlarged end 5 of the member A is made sufiiciently heavy so that it overbalances the bill end and the hook portion proper, and
movement permitted by the formation of the slotted opening, the bill 4 of the hook portion proper will be moved ina swinging path and will also be quickly moved bodily ina direction thatthe bill 4: is withdrawn 'endwise from'the ring 11. The opening at the bifurcated end 7 of the supporting mem- 'ber B might be formed to present a stop to g 7 enlargedend, these 'POSltlOIlS being shown.
.:the same side of the magor axis as the open a limit movement of the member Ain either or both directions, or the formation of this opening might be such 7 that movement of the member A is unrestrained and the eX- treme positions thereof are determined by the balance of the load and the overbalancof the hook portion by the weighted in Figs. 1 and 2. While I have herein described the structure as being made up. and-mounted in a" particular Vmanner, it will be appreciated that changes in the conditions of use would doubtless require variations in the form, and
perhaps in the arrangement; of the parts.
Muchstress is laid upon the mounting of the hook member A in conjunction with the supporting member B so that the member A may have swinging and also shifting movement as an entirety, as it is due tothis combined movement that the bill is positively withdrawn endwise from the engaged and hoisting positions.
