UNITED STATES. PATENT OFFICEV WILLIAM BUTAN, or NEWYoax, N. Y., AssIGNon. To eILLIs a G'EoG'HEGAmor NEW YORK, N. Y., 'A FIRM.

To 'all whom it may concern.' Be itknown that I, WILLIAM RUTAN, a citizen of the United States, residing in the city of New York, 'borough of Queens, in the county of Queens and 'State of New York, have invented a certain new and useful Improvement in Cable-Hooks, ofwhich the following isa specilication.k

The invention relates to hooks intended for attachment to the ends of Wire cables employedY in hoisting operations, and the object of the invention is to provide a hook having the required strength and form which may be economically manufactured' and to which the cable may be easily and reliably secured. y

The invention consists in certain detalls of construction by which the above objects Y are attained, to be hereinafter described and claimed.

The accompanying drawings form a part of this specification and show the invention as it has been carried out in practice.

Figure 1 is a side elevation of the improved hook, showing in dotted lines the cable-end attached thereto.

Fig. 2 is a corresponding plan view.

Fig. 3 is a front elevation with a portion of the hook-horn broken away to show the body and clamp.

Fig. 4 is a horizontalv section, taken on the line lf-4: in Fig. 1, showing the body of the hook and its clamp from below, as indicated by the arrows in such figure.

Similar letters of `reference indicate the same parts in all the figures.

The improved hook is in two main parts, one comprising the body A and horn B, and the other a clamp C adapted to be joined to the body by bolts D extending through the latter and the clamp. n

The bodyv A and horn B are formed integrally, preferably as a drop-forging, the horn extending downwardly from the heavy rear portion of the body having a cross-sectional area equal to or exceeding the root of the horn B so that the full strength of the horn and body is maintained throughout both.

From the body A extends laterally a vertical lange or cheek A1 rhaving on its inner face two grooves of semicircular section with a rib or boss A2 between them, the latter having its llower end rounded. The boss A2 tapers tow-ard the upper end and termiU Specicationof Letters lifatent. v i Patented M3112 9," 1920. application med september 23, 1919. serial No. 325,801.

The roundedlower end termi-v theplane of the beveled face a is outside the cylindrical root of the horn B so that the strength of both body and Vhorn is not impaired. j

The clamp C is the counterpart of' the cheek A1 and has similar grooves with a boss C1 between them, and an inclined or beveled face c matching to the bevel a of the cheek. It is also tapered vertically to correspond vin alppearance to the body A and cheek A1 as s own.

Both the cheek and clamp are bored transversely through the bosses A2 and C1 to receive bolts D located one above the other and having nuts D1 by which the clampV and cheek are drawn together. upon a sharp bight of the cable M lying in the grooves and partially inclosing the bosses. The cable is thus firmly gripped and joined to the hook, and is held reliably without requiring soldering or alteration of the cable-end.

By avoiding rentering angles in the parts, both the body and its horn, and the Y clamp, may be readily formed by the dropforging process. By making the grooves of such size as to receive the cable snugly therein, with theV bend around the lower ends of the bosses as sharp as practicable,

all danger of accidental separation is eliminated-when the clamp is tightened. The open recess below the bosses permits the cable to be easily threaded into the grooves and adjusted while the clamp is in position prior to tightening.

It will be noted that the boss A2 on the cheek Al extends beyond the center line, see Figs. 2 and 4;, and'that the boss C1 is .of less thickness; this construction is preferred for the reason that the strain on the cable in sustaining the load is thus received mainly by the cheek A1 and transferreddirectly to the body A, instead of bythe clamp'and.

through the bolts D.
