T0 all concern:

Be it known that I, .CHRIs'rorHEn and resident ofBellingharn, vin the co nty of hatcom and State of Washinton, `have invented certain new and "usefu Improve- Hauling App aratus, of `which the .following is a 'spec'ctication..`

`referred to as being prevalent in the' operaf tion of' the' other class of bauls 'of common known type. My' invention relates to new and more efficient means Whic',.whle capable of per- .forming the service required in. the 'art of movin aload by.p ullin'g a length' of cable While the end of the 'e' haul isfastene'l onto the load '-inoved, a e, as 'hereinafter-,incre fully" described ari-d set forth, capable "of performing" the functions required iii-,the serv'ceof he art of eliminating-or creating. of any desired zifr'iou'n't of variation yin vthe' cable not engaging t oinfo actiol'iofthe energizing forceson therotatable memberpf theprune mover,

'i v Incident.'A to the v`accomplishing of the prime object of' my invention and-further required in the' service offthevart' mentioned' above, -is the still. morev importantan'd piincipal object of my invention which is .the f moving a load by pulling a length@ 'cable in and Winding' it up while the end-oit -the cable not engaging'the 'haul isa-stenedontb the load lnovedfand, wherein-the variation, in

is reduced .to any desired minimumvariatlon.-

power of the prime Amover throughtwo independent 'mechanical connections. to two 'or more points on the cable. One of the mechanical connections being provided to have one of its members yconnect with the loaded 'cable and pull it in; while. thelother mechanical' cennectionis provided with a member'which winds the cable, thus pulled in by the lirst .named fmeinber, up; and, 'in applying --its- .power 4to thec'able, creates a pull thereon. keeping it tight and preventing it from slipping on the means employed for pulling theA cable` in. To provide driving mea-ns thatf will operate these two independent mechani cal connections, driving theirrespective members that connect with the cable, at the' Varyingv speeds'required incident. to one memberfpul-ling thercablegin and the other member, winding the same cable up, without' using a slipping c lutoh.mechanism'or two independent "prime'movers, I purpose to use an electric motor', ofnany common or well kno-wn type; which, drives' a differential gear of the common-and well knownftype 4such` asb are 'in general use for driving axlesl on tractors and automobiles. [The twoshafts of' this differential being connected up through two -diiierent sets of gear mechanisms to the two independent vmeans for conmotion, received of the compensating action ,variation in `leverage that necting with the one'length'of cable tombe, used by the haul for moving the load. 1

My invention performs the service, here# inbefore described, as l ability to distribute the mechanical power Vof the prime mover through the dierentlal Y gear' and thence through two different setsJ of gear mechanismsrto twodil'erent drums or sets of drums; which, drums, constitute the two independent mechanical connections capable `of applying power to a ,length of cable by one vof them pulling the cable in' :and the other one winding it up. And 'the would oidinarily bel incident to a mechanism while pulling a length of'cable in and winding -it up, and through whicl :fiable leverage vthe prime mover mustm efthe load, is eliminated in4 part or in whole,-as desired and constructed in my invention, by the gear ratios of the mechanisms transmitting the mechanical the prime mover, to the cable at the two independentpoints; and, by of the cable passing from the mechanical means employed 1for pulling it-` in to the. mechanical means employed for windingtliecable up.

constructed in the various di erent hau s as desired Aand arranged to overcome .any deaired Iamount of the variatlon in the leverage the cable up, Toattain the objects .referred to above 1t i J isobvious'that the mlist be delivered requiredl of it, by its -incident to ther increasing diameter of gthe mechanical ,means employed for winding "as it fills .up with cable. For instance: the gear ratios, between the lmechanical means employed for winding 'the Acablejup and thefshaftof thedierentia'l which! drives it, maybe made such'that a re;- duction 'of 25 R. P. M. in the revolutions of the means employedfor winding the cable up`,'incident to its keeping in step with the movementsof the means employed for pullingthe cable in and y'to its increased diameter at the point ofapplication'ot power as it 4lillsup with cable, will cause a reduction of 20 R. P. M. in the revolutions of the differcntial shaft driving it. This reduction of 2O R. P. M., in vthe revolutions of the diil'erential shaft that drives the means employed for win-ding the cable up, will in turn, vby reason ofthe speed of the main gear of the differential having to 'remain very nearly constant in order .for the motor driving it to keep in step with the electrical current ener- *gizing it, cause a corresponding'increase of 20 R. P. M. in the revolutions of the other shaft of the differential. This latter dili'er4 enti'al shaft isthe 'one that drives 'the mechanical means employed for pulling .the

cable And the-gear ratio, between it and :for winding the cable up'. Hence, the meme revolutions ofthe differential er employed for win-ding the cable up, will J lnot slow down and make the relative reduc@4 tion in its R. P. M. that the increased .dlameter, incident to its filling up with cable, ,would tend to require. Thus the pulling inl and winding up of su'icient length of cable to make a variation of 25 RT" P. -M.: in the revolutions of'the member employed for winding the cable up, will make a variation of less than 2R. P. M. in the yrevolutions of the member, employed for pulling the cable in, where most of the power of the prime noer is' applied to the cable for moving the Briefly the elements of my invention are: a prime mover; a differential gear, .of the type in common use for driving axles onantomobiles and tractors; two independent lnechanical means, for connecting with a length ofcable; and a length of' cable in combination with a length ing the hauling apparatus with the load tov be lmoved.
