Be it known thatl, 'KING lV. Ginmisrin, a' citnacnoit"I thc United States, andal resident oliincoln, in the county of Lancaster and,

State,- ofA Nebraska, have made certain new and useful Improvements in' Body-Hoists., of which `theiillmvingiis a specification.

lilyprcseiit invention relates generally to hoists: and more particularly -to hoists for the bodies of. dumping wagons, myyobjcct beingthe provision of a generally .improved structure,y .the operating parts of which follow the lmovement of the wagon body ro-.

Fig. 57 is a-detail vertical section taken substantially. on line 7 7 of Fig. 6, and,

Fig.. 8 Yis aI detailed perspective view of the two parte ofthe sheave support of `the hoist body.

Referring now to rtheseligures, and parlticula'rly .to Fig. 1, niylinvention is designed iior use Vin connection with thebodies of dumping Wagons, andfor location gbetvveen,y tliedriversseat and thev front' end of a wagonllmndyy such as `for instance'ndiicated.l at A." inthe 4said figure, the body being-pim' oted atjitsrear end tofthe running ygear or chassis,` portions of' which are "seen hinges 'or other-suitable pivots.

My invention is designed to be 4interposed l between the front endoittbe body Avand the v .ai ze bi diive1sseat or like for structure, and to this end is intended to occupy but a. minimum space and\still' operatereadily and quickly for the intended purpose.

' For the purpose of my invention, a cross piece 10 is secured` transversely of the run ning gear oi.' chassis B in any suitable manw ner, and provided at' spaced points with brackets 11, in which the depending spaced feet 12 of the main portion of' the hoist frame are pivoted by transversely extending l 'pivots 13 which thus enable the hoist frame to swing forwardly and inwardly of, theY ruiming gear or chassis B, in order to adapt itself-l to the arc of movement of the front end of the body A.

vThe frame of the hoist includes an upper slieavesupport 14, an intermediate tubular 'i upright 15, and an annular invertedn U:

shaped frame 16, the latter Gif-which is preferably semi-tubular in form with av lower -transaferse cross piece 17 and a rigid upright 18 intermediate its side portions, which upright 18 and one of the sidek portions of the said frame have openings 19 and Q0, alined with one another, so asto form bearings for a plurality of shafts 21-22 and 23. y

At its upper curved portion the inverted U frame 4luhas a. sen'ii-tubular extension 2i projecting therefrom 'in a'direction parallel to its longitudinal axis for the reception of the lower end of `the tubular upright 15, which latteris securely fastened by machine screws and thelike 25. .Y

The sheave support 14 shown in detail in F ig. 8 includes two side upriglits 26 and 27 having apertures 28 receiving the side trun miens, or, ends of the shaft of the sheave bve'r which the hoisting cable fpasses. At their extreme upper ends these` side portions 26 and 27 of the sheave support. have curvedr Vextensions Bl'which meet above the space between the upriglits so aste close the latter and prevent ,accidental displacement of the hoisting lcable, these extensions yhaving relativelyengaging lugs and recesses 32 and. ,33 's0 as 'to avoid any-tendency .of 'lateral displacementgfhe lower portionsyothe up ,rightsancl'are anged as at '34 in Fig.

18., and provided nithdepending semi-tubular like.l

extensionse which when together are.v adapted to intert ythe `tubular end of the upright 15 in the, main frame, saideXtQm. lvlsions having interna-l.bosses36,.,one; of

which s an end recess to receive the end lil() ofthe other that thetwo eXtensionsanay-:f f I be temporarily held in proper relative position as they are moved in connected rela.- tion into the upper end of the upright 15 within which they are firmly held by shrinking or brazing or in any other suitable manner.

Vertically along the upright 15 and projecting, rearwardly therefrom at one side of the vertical plane of its longitudinal axis is an upright track 37 having lateral eXtentions 38 and 39adjacent its upper and lower ends, which are bolted or otherwise secured through openings 40 to the tubular upright 15, the lower end of this track 37 having` laterally projecting pins 41, the purpose of which'will be. presently described.

In utilizing my invention, aV bracket 42 is 'provided upon the lower portion of the forward end of the body A, said bracket having a bifurcated arm 43 curved'forwardl-y from its upper portion and having a roller ,F44 mounted in the bifurcation and this arm 5has bifurcated portions which are adapted to straddle the track 37 so that the roller 44 is thus engageable with the rear edge of the track 37.

As seen in Fig. 6 in particular, the bifurcated portions of the arm 43 have recesses which receive the vlaterally projecting pins 41 of the track in the lowermost position of the body A, so as to entirely steady the hoisting apparatus and prevent the same from swinging movement on its lower pivots 13 and rattling against the body.

It is obvious that the body A moves up and down, its arc of movement is compensated for by the lower pivots 13 of the hoist frame, so that the roller 44 will remain in engagement with the rear edge of the vertical track 37 at all times.

One end of the hoisting; cable 30 is sei cured beneath the body A in any .suitable manner, and passes upwardly around the lower forward wear plate 45 of the body, and downwardly around the sheave 29, its opposite end beiner secured to the drum 46 mounted upon theupper shaft Q3 and in con` nection with a lgear wheel 47. vThis gear wheel is in mesh with a gear wheel 4S upon the intermediate shaft in connection with a gear 49 in mesh with a gear 50 upon the lower shaft 21. The lowershat't Q1 is laterally extended beyond one side oi the lower U-fraine 16, and is squared to receive a crank 51, rotation ot' which serves to rot-ale the drum through the series oi `gears 471-46245) and 50, so as to wind the cable 30 upon the drum and elevate the front end of the body A.

The lower cross piece 17 oi the Ushapcd frame 1G has a lateral supporting arm 51 secured thereto for supporting a pivotcd dog.,r engagcablc with the lower `rear 50 in the manner shown in Fig. 14, the dog 52 being secured to one end ot' a controlling rod passing through the supporting' arm 51, and laterally beyond one side of the U-rame 1G with a terminal handle adjacent to the crank 5l, so that the doe,- 52 may bc conveniently moved into and out ot active position. In this way it obvious that when the bo'dy A has been elevated as above described the dog 52 utilized to hold the body in elevated position while dumpingT may be released and the body A thus permitted to lower of its own weight, either after removingl the crank 5l from connection with the squared end of the shaft Q1 or un-I der control of this crank in the position shown.

lt is obvious from tlie foregoing that my invention provides a body hoist which will be simple, comparatively inexpensive, strong. and durable, as well as one which will occupy a minimum space, permit of ready and. quick operations, and avoid all dang'er of the lateral displacement of the parts or rattling thereof in use.

I claimzl. A hoist of the characimdescribed including a lower inverted U-shapedl frame having depending pivotally mounted feet aft the sides thereof, and provided with an upper extension, a. tubular upright interitting the said' upper extension and secured thereto, a sheave support having` extensions inter-fitting the upper end of the tubular upright, a sheave mounted within saidI sheave support, a hoistingr connection ex,.- tending over the sheave, and a winding de vice for the 'hoisting connection mounted within the lower U-frainc, as described.

2. In a body hoist, the combination with a body vertically movable at its forward end and having a bracket provided with a bifurcatcd arm, a' roller mounted within the bifurcation of the arm, a hoisting frame pivvotally mounted adjacent the forward end of the wagon body and lia-vinter an upright track engaged by the body roller, and which the bifurcatcd portions of the body arm straddlc, ay hoisting mechanism carried' by the hoisting' frame and includinga ilexible connection secured at one end of the body, said track having` lateral projections adjacent its lower end and saidbit'urcated portions ot said body `arm having recesses receiving the projections of the track in the normal lower posit-ion of the body to hold the. hoisting' frame `immovable and prevent rattling' thereof.
