DAVID H. LANGAN, OF LEETONIA, PENNSYLVANIA.

TUG-HOOK.

SPECIFICATION Applicationfiled June 29,1293.

.l'o aZZ whom it may can/00in.-

Be it known that I, DAVID H. LANGAN, a citi zen of the United States, residing at Leetonia, in the county of Tioga and State of Pennsylvania, have invented a new and useful Tug-Hook, of which the following is a specification.

This invention relates to improvements in tug-hooks; and myobjects in view are to provide a hook of economic and durable construction, that may bereadily applied to tugs without ripping the same, and will engage with the usual singletrees in a safe manner, thereby preventing accidents by reason of any accidental disengagement, and is also readily applicable and detachable.

Other objects and advantages of the invention will appear in thefollowing description, and the novel features thereof will be particularly pointed out in the claims.

Referring to the drawings:Figure l is a perspective of a hook constructed in' accordance with my invention. Fig. 2 is a vertical longitudinal section. Fig. '3 is a detail of one of the hook-members. Fig. 4: is a central transverse section. Fig. 5 is a perspective in Like numerals of reference indicate like partsin all the figures of the drawings.

In practicing my inVention,I construct the hook proper by the assemblage of two similar members, each of which consists of the front hook-portion 1, immediately in rear of which is an upwardly-disposed lug 2, about half the diameter of the hook 1, and at a right angle to the shank of the hook. The shank of the hook is extended in rear 'of the lug 2, as at 3, and at its extremity or near the same is provided with a right angularly disposed stud 4. The stud 4 is parallel with the h1g2,

is centrally and longitudinally bored as at 5,

and near the lower end of the bore is 'provided with screw-threads 6. The inner end of the stud is reduced externally, as at 7, and at one side is provided with a lug 8. The hook-portions l have their inner faces inclined or tapered toward their extremities, so that when the two members are assembled, as shown, the inner f faces lie flatly against each other, and said hooks combine to form a closed hook,adapted to be separated for the reception of a cockeye or link. Previous -6 of one of the studs.

forming part of Letters Patent No. 508,521, dated November 14, 1893.

Serial No. 479.14=1. (No model.)

to assembling the two members a split springcollar 9 is mounted upon the reduced portions 7 of the two studs 4, said collarbeing of a width equaling thelength of the two reduced portions, and its split portion 10 receives the two lugs 8 of the abutting studs. The studs are encircled by a sleeve 11,within which the studs may partially rotate, and a bolt or pintle 12 is passed through the bores 5 of the studs and is threaded at one end in the threads The bolt serves to secure the members together, and the springcollar to maintain them in alignment, and their hooks in contact, and therefore closed, but yieldingly separable. In order to connect the described "hook with a cock eye, ring or link, the two members are pressed apart or separated, and the cock-eye, ring or link in- V troduced through the space between the separated hooks of the members, and as soon as released, the spring-collar acting against the lugs 8 serves to return the parts or members to alignment, and therefore close the hook. As the hooks of the members overlap each other, it will be seen that the greater the strain or draft thereon, the more securely are they looked, so that an accidental separation is impossible.

It will be seen that the herein-described hook may be readily applied to the eye of a trace or tug, without any ripping whatever of the stitches or removal of the rivets thereof, so that it is capablejofta'king theplaoe of the ordinary tug-hook when broken. In such substitution, the hook-members are separated and the parts assembled at opposite sides of the eye of the trace, in the same manner as heretofore described.

Having described my invention, what I claim is 1. The herein-described improved hook, the same consisting of opposite members, terminating at their front ends in overlapping hooks and at their rear ends provided with inwardly disposed hollow studs, abutting against each other, a .bolt passing through th hollow studs, a spring located on the studs for maintaining the overlapped hooks normally in contact, and a'sleeve loosely'inclosing the studs, bolt, and spring substantially as specified.

2. The hereindescribed improved hook,

the same comprising opposite members, terminating at their front ends in overlapping hooks, and provided at their rear ends with hollow inwardly-disposed abutting studs, reduced at their inner extremities and provided with aligning lugs, a split spring collar mounted on the reduced portions of the lugs, and at its split receiving the lugs, a sleeve mounted on the studs and loosely fitting the same, and a bolt passed through the hollow studs, substantially as specified.

3. The herein-described improved hook, the same consisting of the opposite members, terminating at their front ends in diagonallybeveled overlapping and contacting hooks, in rear of the same having inwardly-disposed lugs adapted to contact and form the back of the hook, and at the rear ends of theirshanks having inwardly disposed abutting hollow studs, the inner extremities of which are reduced and provided with aligning lugs, one of said studs being provided at its outer extremity with internal threads, a spring-collar mounted on the reduced portions of the studs and having a split for the reception of the lugs of the studs, a sleeve encircling the studs and abolt passed through the studs and having its threaded end engaging the threads of the stud, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

DAVID H. LANGAN.
