,r The invention vrelaties.generally toxj'hoists r and .more particularly to :power driven hoists capable of receiving the driving power vfrom a ysource such as a motorl vehicle. .-'I'The primary'object ofthe invention is to provide ay nevv'and improved" hoist which is adapted to be'readily attached to or removed `fromasuitable.sourceofpower. L v kIt has generallybeen'customary in the art pertaining to devices of this character to provide` hoistsinfwhich'ra reversing faction of the ypower drive -is-essential-to effect a raising and vlowering movement thereof. This'feature has' been objectionable sincethe manipulationlof such a hoist is acomplicatedoperation.- 1 Another obj ect of the invention therefore' is to provide a detachable hoist in which operation" thereof lisfefected byv a driving means which moves constantly vin one" direction.` f n Anotherfobject of theinv'ention is to provide a hoistwhich may be readily attached to a motor vehicle to be driven thereby, .which hoist includes* a m'anualfcontr'ol enabling an operator,v at will,`t'o 'effect a raisingor lowering Vaction ofthe hoist, tofs'topy and hold the hoistat any desiredu point or instant, and to permit the hoist Tto A'remain idle.r independentf ly ofthe movement ofl the ldriving means;

rged .front view a part illustrated herein resides ingxthel adaptability of thehost to be incorporated on any `form Y of motor vehicle, and while it is illustrated lanjdwill bedescribedin this capacity, it will be kunderstood thatthe hoist is quite asreadiyly capable of beingv permanently,attached to a stationary ydriving means, suchas an electric motor or gasoline engine or the like.,

v Describing the invention first in` abrief general manner, 'the `(hoist comprises la securing base` 10 preferably mounted perma-v 65 -nently on one of the wheelsll of a vehicle which is, in ,this instance, the left reariwheel. The hoist proper' isY secured to the base lO in any manner permitting rapid. attachment4 and detachment therefrom and includes a stub i shaftor auxiliary axle, generally designated 12, arranged to rotate withthe wheel. -A vWinding drum 13 is rotatably mounted on the shaft 12 l.and has on one sidethereof'a driving Aconnection with the shaft. through vthe f intermediate agency ofjaclutch mechanism 14.' The drum is ,also arrangedtobe engaged bylmeans of arsuitable friction brake device 15l for preventingk the Jlrotation of the drum.

v Anfoperating leverior vhandle 16V is pro- 80 vided for the manipulation of thehoist and i is so arranged with respectltotheclutch and brake mechanisms thatuneither will interfere with, the operation of the other. Thatis tosay,the clutch and the brakeoperate indi- 85 `vidually land such operation is controlled by Y the y,single manually operable handleV or lever 16 jwhich upon movement .in one direction eects ai drivingjengagement betweenthe f adaptedv to be secured permanently upon the wheelto which end a pluralityiof U-shaped n bolts18 are appropriately disposed about the outerperiphery of the lring to be iitted around certain of thevspokes v19 of the wheel. 100

vides a bearing upon` vwhich provide three separate external bearing surfaces, of which the inner and the largest diametered surface 2O provides a surface upon y which they brake device is mounted, the outer Yand smallest di'ametered surface 21 -providesfa mounting "for the clutch device 14, and theinter'mediatesurface 22, the diameterl of'whichis intermediate the diameters of the brake and clutch surfaces, prothe drum as- `semblyv13 is mounted, y TheV shafty 12 adjacent the inner end has van integrally formed-radial flange 23 thereon'arranged to abut the ring 1-0 on the wheel 11'.v The fla-nge 23 is spaced a short distance from the end of the shaft to lprovide an axially extending shoulder 24 which is accurately machined orV otherwise finished to "fit snugly within the correspondingly finished inner periphery of the-ring. y A

The shaft may be securely mounted on the ring through the ilange23 inv any preferred manner, as byy providing a plurality of outwardly projecting studs 25 on the ri-ng 10, whichv `studs extend through appropriately positioned apertures 26 in the flange 23.V The studs are screw threaded at 4their outer ends toreceive a nut 27 thus securing the shaft 125 to the ring 10. By this construction vthe shaft-may be properly positionedonthe ring by the abutment of the shoulder 24 and the flange 23 with the ring and thenbe rigidly secured vin place lwith a minimum expenditure of time andlabor. Since the ring has beenpreviously trued with respect tothe wheel, the shaft will also be accurateli mounted on the wheel. As maybeSeen in the drawings amplespace'is provided within the brake sectionof the drum to receive therein 'the' hub-capassemblyof any vehicle.

'The drum assembly 13in thisV instance comprises a central portion orhub 28 having a pairY of spaced outstanding eircul'arwalls 29, 30 thereon.' T'The drum is somewhat shorterthaln2 the hub 28, which is substantially as long as the intermediate section 22 of the shaft',v thus providing an extensionwhich,

. in effect, isanaxialfsleeve 31A integral with the drum.V The sleeve i's-arranged to be engaged; by a pa-rt'of the clutch mechanism as will be presently-described The outer wall.

^ofgthe drum preferably carriesthereon a i means by, which one end of a cable: 32fma-y be secured'to the hoist. Thisfmeans-as shown in Fig. 1 comprises a bolt 33 permanently mounted on the wall 30 to extend outwardly therefrom and is screw threaded to receive a V nut 34, between which and the wall of the drum the cable 32 may be secured. Since the cable is thus secured'externally of the hub of the drum a suitable aperture 35 is provided in the wall through which the cableV may be passed to be wound on the drum. In this construction the aperture is positioned relative to the securing means in such manner ,that the cable 32 will be drawn onto and released from the lower side of the drum.

The clutch mechanism 14 may be of any preferred construction which will provide a positive driving engagement between the shaft 12-and the drum' 13. In this instance I have showna clutch mechanism comprising an engaging member. in the form of a split collar 36 (Fig. 4) which is mounted relatively loosely on the sleeve 31 of the drum 13. The collar 36 is adapted, when the winding drum is at rest, toA rotate loosely upon the sleeve-31 and is formed of a suitable somewhat resilient material whichnpermitsthe split ends 37, 38 of the collar `to be drawn together thereby tightening the collar tol such an extent thatza frictional engagement between the sleeve 31 and the collar l 36 is produced. At a suitable position upon. the-col.- lar, which, inthis instance, is diametrically opposed to the gap. therein,r an integral radial lug39 is; provided which projectslaterally beyond the sidesof the collar.. The laterally proJecting portion is notched, as at 40,1.; to

described.

A plate 41 of substantial thickness4 and preferably circular in shape .is mounted about thel smallest diametered or clutch Section 21 of thev shaft adjacent the outerfend of the intermediate section 22 carryingfthe drum. The plat-e is. secured to the shaft, 12 for rotation therewithby any suitablemeans, suchfas the key 42. On one side of the plate a radially extending Vfinger 43" is; formed which is adapted to extend into and beengaged by the notch 4Q in. the laterally pro,- jecting portion ofthe collar. In this, manner, at driving connection with, the Vshaft is provided for the collar.V

The preferred form lof the means by which the split" ends 37, 38` of the collar 36 are drawn together to engage the collar with, the drum slee-ve 31 is `shown in Figs. 2 and' 4. On one split endk ofthe collar, in this instance the end 37 ,a pair ofaxially spacedlugs 44 are, provided which have registeringopenings therein to actas bearings for apin 45'. The pin is-formed so that the portions thereof which are j ournaled' in the lugs 44 areon the main axis of the-pin. fMeans, such astheend38 of the collar.

After the hoisthas been attached ron'fthevehicle,` the cable, which is generally carried upon the drum when lthe-hoist is not inuse, is ledk through the usual pulleys and the-like.Y (not shown) which are necessary in the particular hoisting job'to be done.

Due to the construction of the hoist, the loperating, handle or .lever Will extend to convenientV position adjacent the drivers seat;

Where the operationof the hoist maybe controlled in-:the manner-Which has been pre;

rviously set forth.r It Will-beapparent that the hoist may be convenientlyoperated since thev operator is ina position at all times to observey the raising and lowering action-vof; the hoist. Thus, when it isy desired t'o raise v Vsome object, the operator may movey the lever b outwardlyto engage the clutch and initiate the hoisting movement.- The speed atvvhich the hoist operates may be controlled by the speed of themotor operating through any-of` thefcustomary.changespeed gears in the transmission. AWhen the object vbeing hoisted has been lifted to desired height,the

leverk may bemoved rapidly inwardly to disengagethe clutch and to engage the braking mechanism regardless of the speed at whichl the hoisthas 'been operating. The lowering movement of 4the hoist is'controlled solely by the brakingmechanismyvhich may be entirely disengaged to permit a rapid loweringL of t an object or which may be slightly engaged to effect-a slower'controlledldescent of-an object.
