' I This invention relates to devicesqf or hanging the pulley block of a hoisting cableto a in the raising and lowering of logs in car loading operations." 1 In apparatus'of thischaracter it is deemed necessary to have} the hanger" adjustably mounted upon the guy line so that the pulley :block may be brought into a position suitable for loading operations; and, when thus regulated, provision'fmust'be made for securing the hanger 'to theguy-line. e

Certain known pulley block supporting devices designed for this class of work are 5 objectionable because of liability of beinginr as I with the r to securely fastened to the supporting ,cable;

others are objectionable because the fastening means therefor are di'flicult to manipulate in engaging and disengaging the same with' respect to the supporting cable; and others, again,.are" objectionable because they subj ect a'supporting cableto stresses and strains seve'rly injurious to the cable;

The object of the present invention is to provide ahoisting-cable pulley-hanger Whlch will overcome the objections above referred to and others; which will be convenient to shift from one position to another and be secured at a desired position to the support- 'ing cable', and which will be peculiarly efiicient in operatioir p A further object is'to p-rovidea strong and durable construction of hanger-frame, in which the securing parts are readily acces- These, and more specific objectsjtogether" t' '11 advantages of the mven lon W1 wheel are apertured to receive a transversely disposed bolt .18 to support a link 19 which,

pearin the following description. I v p The invention consists in the novel con' struction, adaptation and combination of parts hereinafter described and claimed. In the accompanying drawing,- Figure l is aview in longitudinal vertical section of pulley-block supporting devices embodying myinvention, illustrated in engaged relation with a cable shown in side elevation; F ig. 2 is an end elevation and Fig. 3 is'a view, partly in horizontal section of Fig. 'lywithxtho cableomittedp M Fig. 4 is a pictorialside elevation to. illustrate' the application of the invention."

Referring fi'r stto Fig. 4, the numeral 5 designates a cabletwhich, asshown, is utilized,

as'a guy for a post 6 the lower'endof the guy being secured to an ancho r such, forje xample, as. aft'ree stump :7. Thefpurpose of r the inventionis to provide means for attachlngto the'c'able 5 a meansf8, l erelnafteifjdesignated generally as the carrier, whereby the cable serves to support apulley block!) pro vided with a sheave '10' for a hoisting cable 11 employed in the/loading of logs.

The carrier 8,. preferably of cast meta ll, H comprises two laterally spaced side plates 12 3 Which'are connected at the top bytwo-longitudinally spacedfblock elements 13 ;'and, intermediate their depths, 'each of the side plates 12 is provided at its inner side with a ledge 14 extending the entire. length, preferably, of the'carrierQ I i Between said block elements l3,'thef respective side plates '12 are provided with a pin Iii-which is disposed transversely of the carrier and constitutes the axle for a peripherally grooved wheel 16.

- In its underside each of the blocks 13 is provided with .a longitudinal groove 17,

which is arranged to slope upwardlv from the inner to'tlie outer end thereof, so that the grooves of both blocks taken together will be disposed in angular relationonewith the lothe'ri The positioningof the block grooves, moreover, are'suchthat the anglethereof is below the'p eriphery of the 'grooveof the wheel 16.

The side plates of the carrier below said.

in turn, engages witha hook or link 20 (Fig.

4) provided on the pulley block 9 to support the same.

The grooves 17 of the respective block ele- 'ments 13 areprovided with series of recesses '21 formed-.as to shape and re1ativeposirier ledges 14 and has in its top a longitudinal channel 23 of a segmental circular shape in transverse section to accommodate the underside of the respective portion of the cable5.. ,v A,

Thitwed channels, unlike the grooves in the block e ements 13, are smooth (not corrugated) to permit unobstructed endwise movement oflthe wedges with respect to the cable in effecting the upward flexing of the cable to have the strands thereof engage within the respective recesses 21 of the block element grooves. a i

The wedges are driven byhammer blows into positions to set the'cable into engaged relation, as above explained, with the carrier and, to h'ol'd'the wedges in positions to retain the cable in such engagement, I pro vide a scr w threaded coupling bolt .24 extending through apertured lugs 25 of both wedges, the head 26 of the bolt engaging the ,lu of one wed e anda nut 27 screwedon the r tengagingt elug of the other wedge.

To afford movement of the carrierto a selected position along the cable 5, the wedges 22 are withdrawn from the carrier.

The cable then straightens as represented by dotted lines 5 in Fig. 1 with a consequent disengagement of thecable from the carrier and transferring the weight thereof (togethenwith that of other parts associated therewith) from the giriooves 17 to the rotary .wheel 16 which trac ng on the cable, ren-' .ders easythe shifting of the carrier.

It is tobe noted that the carrier is secured to the cable'by bendingthecable to cause the cable strands to engage in recesses provided therefor 1n the carrier structure.
