T his invention relates to hoisting cable attachments and has particular reference to a butler weight therefor e An important object of the invention is to provide a buffer weight for cables of compact and durable construction which may be readily secured in position upon a cable whip, I l p v A further object of the invention is to provide a device of the above Cl'lfilZtCtQl' adapted to prevent ouling-of the cable hook.

Still another object oi the invention is to provide a device which will aid the descent of the unloaded cable and hook.

Other objects andadvaiitags of this invention will become apparent as the description progresses.

In the accompanying drawing forminga part of this specification and in which like numerals are employed to designate corresponding parts throughout the same:

Figure 1 is a side elevation of my improved buffer weight, 7

Figure 2 i's a central vertical sectional view taken through the device as shown in Figure 1, I

Figure 3 is a horizontal sectional View taken on the line 33 of Figure 2', v

Figure 4: is a similar view takeh on the line 4- 4 of Figure 2. I

Figure 5 is a similar view taken on the line 5 -5 of Figure 2, and

Figure 6 is a perspective view of a re-' taming; member used in connection with my improved device. c In the drawin wherein for the purpose of illustration is shown the preferred .embodirnent of my invention, the numeral 10 generally indicates a portion of a cable or whip carrying at its-lowerextremity a conventional type of cable hook-11', The cable hook is secured mam cable by means of a ring 12 the 'endojtthe cable being doubled about the ring and secured by a pair of spaced U -b'olts 13 or in any suitable manner.

My invention resides moreparticula rly in the provision of abuffer weight to be mounted at the end or the cable adjacent the cable book so as to the descent of the unloaded cable and permit the same to run freely over the pulleys. The weight is so formed so as to prevent engagement of the cable hook with a second cable hook or other objects. The whip weight or buffer embodies a body 14 of elliptical shape circular in cross section, the upper portion 15 being of reduced diameter to form an annular shoulder 16. The lower portion 17 is of substantially increased diameter, the purpose of which will become apparent as the description progresses. The central portion of thebody 14 is provided with a longitudinal comparatively large bore 18 extending frornthe lower end to within a slight distance of the upper extremity terminating in'a reduced opening ISeXtending through the upper tip portiouof the body, ,The lower extremity of the bore 18 extends entirely through the body and is provided with an annular groove 20 adjacent the lower tipof the body, this groove being somewhat greater in diameter than the bore 18. p y, I

To facilitate the assembly of the device, the body is preferably formed of two complementary half-sections provided with outwardly extending longitudinal tongues 21 en'gageable with suitable recesses formed in co-actin-g relationin the opposite portions of the sections. With particular reference to Figures 1 and i it will be seen that each sec tion carries a pair oftlietongues 21 in parallel arrangedpositionsat each side of the central bore andis alsoprovided with a pair of recesses formed adjacent the projecting tongues. This construction permits the body sections to befiirrnly connected lateral movement 'so that the central faces will be in contact, 'lhese body sections are maintainedina ssociated positi onsby means a ring preferably of metallic construction tightly insertedover the upper reduced pop. tions of the sections and adapted to rest upon thebody shoulder 16 as shown toadvantage in Figure 2.

The i'oregoing description clearly defines the construction andinanner of assembling myimproved whip andbiifiter and I will now 'endeavor to indicate the manner of mo ting the thr c iad he l e of a cablehook q rejvenrmaerni movement of the weight. ls previously noted, the lower portion of the weight body 14 is rror d idiwith an. n ar erq v 20,3this grooye being adaptedio receive a cable engaging collar 7 23. This collar or sub- 'stantially joircular formation durably constructed and provided with a comparatively wide slot 24. With reference to Figure 6, it is apparent that the slot 24 extends through the greater portion of the collar, the extremities of the collar adjacent its open ends being recessed to receive a movable segment 25, this segment being of sutficient thickness to fit flush within the recess. One end of the segment 25 is pivotally mounted on the collar by means of a pivot pin 26, the inner edge of the segment having an arcuate slot adapted to coincide with the longitudinal slot so as to engage the double end oi the cable 10 therein.

To disconnect my improved whip weight and butter from the cable hook it is necessary to elevate the ring 22 on the upper portion of the weightbody 14: so that the body sections may he laterally disengaged. This will tree the body from the cable but permit the collar 23 to remain in position thereon. The collar is then removed by swinging the collar segment 25 outwardly so as to permit the collar to be readily sepa ated from the cable. In assembling the device upon the end of the cable, the collar first mounted in position upon the doubled end at the cable between the securing bolts 13 and the weight sections mounted in position. The provision of the laterally ex tending tongues 21 will prevent longitudinal movement of the weight sections and the ring 22 will prevent lateral movement so that the weight may be assembled and retz'ned firmly in position upon the cable hoolc.

It is apparent, from the foregoing, that a whip weight of compact construction is provided formed so as to provide a butler to prevent fouling of the cable hook. it will be further noted that the device is designed to be very easily mounted in position on the cable and connected so as to prevent accidental displacement.

It is to be understood that the form of my invention herewith shown and described is to be taken as the preferred example of the same, and that various changes as to the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention, or the scope of the subjoined claims.

Having thus described my invention, I claim:

1. A device of the class described includ ing an elliptical body having a longitudinal bore formed therein, means for detachably mounting the said body upon a cable hook, a cable engaging collar mounted in the lower portion of the said body, and means for detachably associating the said collar with the said cable.

2. A device of the class described including a substantially elliptical body having a longitudinal bore formed in the center thereof, the said body having a pair of complethrough the bottom extremity of the body and the upper end terminating in a reduced opening, the said body being composed of a pair of sections, outwardly extending tongues formed in the intermediate portion of the sections engageable with suitable recesses, means for retaining the body sections in co-acting positions upon a cable, and a cable locking ring movably mounted in the intermediate portion of the body engageable with a cable or the like.

4;. A whip weight and butl'er comprising, in combination, an elliptical shaped body having a longitudinal bore formed through the center thereof, the upper end terminating in a reduced opening, the upper portion of the body being of reduced diameter to provide an intermediate shoulder, the body being l'ormed of two complementary sections, laterally extending ears formed on the abutting edges of the sections and engageable with oppositely disposed recesses, a ring member adapted to be snugly fitted. on the upper portion of the body to retain the body sections in compact position, the lower portion of the body being provided with an internal annular groove, a locking ring movable in the said groove, the said locking ring having a pivoted segment on gageable with a cable hook for retaining the whip weight in position.

In combination with a cable whip weight having an annular groove, a circular cable engaging ring mounted in the said groove, the said ring having a transverse slot for engagement with the cable, and a pivoted locking segment mounted adjacent one end of the ring for engagement with the cable.

6. A cable whip weight comprising an elongated body formed with a longitudinal bore througlrits center, the said body including a pair of laterally detachable sections, a ring removably mounted in the body adapted to engage a cable, and an exterior ring adapted to be slidably fitted on the body sections to lock the same in position about a cable.

In testimony whereof I afiix my signature.

CHARLES W. LEXVIS.
