A TTOR/VEYS JOHN "IIJ'TSlVJIAN, OF FULLERTON, LOUISIANA.

LOADING-HOOK.

Specification of Letters Patent.

' Patented Nov. 9, 1915.

To all whom it may concern Be it known that I, JOHN U'rsnAN, a citizen of the United States, and a resident of Fullerton, in the parish of; Vernon and State of Louisiana, have invented a .new

and useful Improvement in Loading-Hooks,

of which the following is a specification.

T his invention relates to an improvement in loading hooks adapted more particularly for use in loading logs and the like, and one '-of' the principal objects of the invention is to provide a hook ofimproved construction, and having an adjustable cup and pin which may be removed when necessary,for sharpening or substitution of new parts.

Another object of the invention is to provide an improved hook of the class described which will be extremely simple, durable, efficient in operation and inexpensive to manufacture.

With these and other objects in view, which will become apparent as the description proceeds, the invention resides in the construction, combination and arrangement of parts hereinafter more fully described and claimed, and'illustrated in the accompanying drawing in which like characters of reference indicate like parts throughout the several figures, of which,

Figure 1 represents a view in elevation of a hook constructed according to my invention, Fig. 2 represents a vertical sectional view taken transversely therethrough, on the plane indicated by the line 22 of Fig. 1, Fig. 3 represents a view in section taken horizontally on the plane indicated by the line 3-3 of Fig. 1, looking in the direction indicated by the arrows.

In carrying out my invention I provide a hook, whose body portion is substantially right angular in shape and consists of a shank 5, having an eye 6 provided at its upper end for the reception of a hoisting cable or the like, and provided at its lower end with a right angularly extending foot or toe 7. Toward the inner end of the foot, the same is'provided with an opening or eye for the reception of a smaller rope or cable, not shown; The eye is indicated at 8, and the materialof the hook may be cut away adj acent the ends of the opening, if desired. The outer end of the foot is provided with a cylindrical enlargement 9 which extends substantially in parallel relation with shank 5, and which at its upper edge 10 extends or lies in a plane above the upper edge of foot 7 The cylindrical enlargement 9 is provided with a central tapered bore of down wardly decreasing diameter for. the recep tion of a: tapered pin 11. The latter is pointed at its upper endasat 12, and at its lower end is adapted to be mashed, or turned over, or flattened against the lower end of theenlargement 9, for riveting the pin in place, as

indicated at 13. The cup consists of a tapered body portion 147 having a central bore 15 for the reception of the cylindrical enlargement 9, over 'which said cup is adapted to fit The upper end of the cup is hollowed out or concaved as at 16, and the edges of the cavity are sharpened as atl'Z. Connecting bore 15 with the cavity 16 is a smaller tapered bore 18, through which pin 11 extends. The bore 15 thus terminates at its upper end in a shoulder 19 which rests upon the upper end of the enlargement 9. The lower portion of the body 14:, is provided, as clearly indicated in Fig. 3, with a radially extending recess or slot 20 for the reception of the outer end of foot 7, said slot or recess being of a width substantially equal to the thickness of the foot. This recess extends from the bore 15 to the periphery of the cup, and from the lower end of said cup to a point adjacent the shoulder 19. The cup thus engages upon the foot 7 in such manner as to be retained against rotary movement relatively to the foot. When it is desired to resharpen or replace the cup 14, the same may be lifted off the hook subsequently to the removal of the pin 11, said cup' being maintained against removal from the hook by reason of the tapered pin engaging in.

the smaller tapered bore 18 of the cup. When it'is desired to remove the pin for renewal or sharpening, the lower riveted end thereof may be sawed or filed off, and the pin readily removed.

Although I have'described the preferred embodiment of my invention, I may desire to make such changes in the construction,

combination and arrangement of parts being provided at its outer end Witha cyline d nd adapted, at its lower nd to; be

I mashed upon the enlarg'ernent for inaintaiin ing the pin in place, and a cup, said cup beingprovided With a central bore for the reception of the cylindrical enlargement, said oup'being provided at its upper endvvith a ooncaved portion provided With-sharpened edges, saidjcup having atapered bore con- 1 nect-in'g thefirst said bore with the'eavity and through which the tapered pin extends,

said cup being further provided'ivith are oess'eXtendi-ng' from first said bore to the periphery of the cup and adapted to receive the outer portion of said foot, substantially as described.

2.- The-herein described hook, consisting of a right angularl'y formed body portion havingan enlargement at one end, a cup providedwith 'a bore for the reception of'the enlargement and With a recess for the reception of the adjacent portion of the body, said "cup being concaved at its upper portion and having the edges of the cavity sharpened,

Gopis of this patent may be-nbtei-ned for the cup and having'a pointed end extending beyond said cup, said pin being detachand a pin arranged axially with" respect to 7 ablyengaged With the enlargedportion of 1 the hook.

, 3.A,;.device of the class described, @1 1- prising a body portion having an enlargement at one end, said enlargement being provided With a tapered bore, a tapered pin de- .tachably disposedwi'thin. said tapered bore,

being sharpened atjoneend, a cup havmg a bore recelv ng the enlar ed portion,

said cup being adapted to engage said body whereby to prevent rotation of said cup,

said clip being provided'with an'a'nnnl'ar" sharpened edge surrounding the pin.

4. The herein described hook consisting,

of a body portion having an enlargement at one'end, a tapered pin arranged Within" a bore providedin the enlargementand being mashed over-at lts; smaller end against sa d enlargement, and a cup detachably arranged tion thereon and encompassing said enlarge- 50" upon the enlargement and held against 'rotaa ment, said cup providingan annular sharpened'portion surrounding the pin.
