TRUCK Application filed July 21,

T 0 all whom it may cance n:

Be it known that l, WILLniir rl. RniasnN,

a citizen of the United States, residing Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful lmprovements in Truck Hoists, of which'the following is a specification.

My invention relates to improvements in lidists for raising the bodies of motor trucks to dumping position and for lowering suchbodies after the loads have been dumped.

One object is to provide a new, compact and powerful mechanism of this character which can bereadily installed on a motor truck and geared to the'engine of such truck, so that the truck body can. be raised and lowered by power instead of resorting to manual'labor.

A further object is to provide new and useful means for automatically throwing the hoisting mechanism out of gear when the truck body reaches the end of its upward and downward. movements, and thus avoid damage to the mechanism by neglect of the driver to throw it out of gear.

Other objects will hereinafter appear andv in order that the invention may be fully understood, reference will now be had to the accompanying drawings, in which:

Fig. 1 is a broken side elevation of a motor truck equipped with the hoist.

Fig. 2 is an irregular vertical section of the hoi'stand a portion of the truck, taken on line ITTI of Fig. 3.

Fig. 3 is an irregular vertical section taken on line Ill-ill of Fig. 2.

Fig. 4 is a fragmentary plan view, partly in section, of a portion of the throw-out mechanism.

Fig. 5 is a fragmentary section'of part of the mechanism disclosed by F ig. 2.

Fig. 6 is a fragmentary vertical section of a modified form of the throw-out mechanism.

Fig. 7 is a fragmentary vertical section of another modified form of throwout mecha nism.

Fig. 8 is a fragmentary vertical section of another modified form of throw-out mechanism.

A, designates a motor truck equipped with the usual chassis B and body C, which latter is mounted adjacent its rear end on pivots D li r till"lliiltl ll" I KANSAS CITY, MISSOURI.

1921. Serial to. teens.

carried by said chassis B. All ofthe fore going is of usual construction;

Referring now more particularly to the parts constituting the present invention, 2-

designates an upright housing provided with bearings 4 at its lower portion in which a drum shaft 6 is ournaled. Said drum shaft 6 is equipped with a fixedly-mounted centrally disposed worm wheel 8 and drums l0 and 12 disposed at opposite sides of said worm wheel 8. Cables 14 and 16 for raising and lowering the body C are attached to the drums 10 and 12, respectively, and the arms 18 fixed to the front end of the body C.

The cables 14 and 16 run around guide "14 and 16 extending from the respective drums 10 and 12 to said sheaves 22. The

free ends of the brackets 26 are supported by braces27, mounted at their lower ends on pivots 29, fixed to a bar 31 in the housing 2.

The worm wheel Sis drivenin both directions to effect the raising and lowering of the truck body C, from the propeller shaft E, through a train consisting of a sprocket As shown on Fig. '2, the tubular porwheel 34 driven by the sprocket wheel 32" through a chain 36, a sprocket wheel 38 fixed to the hub 40 of the sprocket wheel 34, a

sprocket wheel 42 driven by the sprocket wheel 88 through a chain 44, a cog wheel 46 fixed'to the hub 47 of the sprocket wheel 42,

a cog wheel 48 driven by the cog wheel 46, a worm 54, a worm wheel 56 driven by the worm 54, a worm 58, an intermediate clutch member 60, and clutch members 62 and 64, on the hubs of the wheels 38 and 48, respectively. The hubs of the wheels 38 and 48, are spaced apart and loosely mounted upon a shaft 66 journaled in bearings 68 and upon which the worm 54 is fixedly mounted. The intermediate clutch member 60 is splined upon the shaft 66 and disposed between the clutch members 62 and 64, so that'it can H :by; -alever 72. fulcrumed. at 74 and manually controlled throng-1;...the 1 intermediacy, of a.

In the modified form Fig. 6, the construction and operation are substantially the same as in the preferred .iorm, excepting that the rods 86*, operate in tubes 15, secured. attheir lower ends by hingeslT to thezfrontof-the. bodyCi.
