WAGON-BODY LIFTER.

Specification of Letters Patent.

Patented Dec. 5, 1905.

Application filed MHJGh 211 1905- Seria-1N,- 251,318.

To all whom it may concern,.-

Be it known that I, CHARLEY WILLIAM Rn-y NEAU, a citizen of the United States, residing atA My invention relates to wagon-body lifters;`

and its object .is to provide asimple, durable,

and inexpensive device of this character hav-1 ing means whereby wagon-bodies of different forms may be lreadily lifted from their running-gears and supported until it is desired to lower them into proper position.

With the above and other objects in view the invention consists of a frame suitably supported and having centrally-disposed powerwheels secured to a rotatable shaft which is providedwith an arm pivoted to a supporting-prop. Ropes or cables rextend from the` opposite portions of the peripheries of these wheels and over supporting-pulleys provided for them.l and the lfreeends of these ropes or cables are connected by cross-strips to form swing-like devices.

- has secured tofit two power-wheels 5, each of" The invention also consists in the further novel construction and the combinationsnof parts hereinafter more fully described, and pointed out inthe claims.

In the accompanying drawings I have shown the preferred form of my invention.

In said drawings, Figure 1 is a perspective View of my'improved wagon-body lifter and showing by dotted lines awagQn-bodyin position to be lifted thereby. Fig. 2 is a side elevation showing the position of the parts after the wagon-body has been raised; and Fig. 3 is a longitudinal section through the lifter, showing the positionswhich may be assumed by the swinging portions when not in use.

Referring to the drawings `by numerals of reference, 1 1 are standards of any suitable length which support a frame 2, having longitudinally-extending beams 3 therein and between the sides thereof "on which is journaled a shaft 4. This shaft extends transversely of the frame at the center thereof and which has a grooved periphery. Anarm 6 is secured to the shaft and is adapted to rotate therewith, and this arm is pivoted to the upper end of a prop 7, which is ofsuch length `Vin Fig3.

as to 'support the arm normally in a horizontal position.

The cable'or rope Sextends from diametrically opposite points on theperiphery of each wheel 5 and is supported on pulleys 9, journaled on the. frame. Each of these pulleys is journaled in bearings 10. arranged on strips'3 and on auxiliary strips 11, which are arranged between, and parallel with, strips 3 Vand are connectedthereto by cross-pieces 12.

The lower vfree ends of the ropes or cables V8 are secured to the'ends of supporting-strips 13, which with the ropes or cables constitute swing-like structures for extending under and supporting a wagon -body. While the cables or ropes may be fastened in any suit- Y ablemanner to opposite portions of the power- `wheels 5, I preferably provide each wheel with a passage extending through the center thereof anollthroughwhicah the rope or cable extends. 'IheHropes or cables are so disposed Aupon the power-wheels that their points of connection therewith are inV a horizontal plane when arm 6 is in its normal position.

When itis desired to lift the wagon-body, the vehicle is driven between the standards 1, and the supporting-stripsA 13 are placed under opposite endsof the wagon-body 14, which is shown vby dotted lines on Figs. l and 2. The lower end of prop 7 is then moved either back-ward or forward, so that the arm 6 can be pulled downward thereby, and said arm is thenl swung around until it extends in a direction from shaft 5 opposite to that origif'nally assumed, therebyl imparting a one-half revolution to each Vof the power-wheels and causing the ropes or cables to be partly wound thereon. The supporting-strips 13 will therefore be raised 'and will lift the wagon-body from the running-gear of the vehicle. It will of course be understood that the arm 6 can be held in its new or adjusted position by the prop 7, -as shown in Fig. 2. To lower the wagon-body, it its merely necessary to rever'se the operation above described. When the lifter is not in use, .the supporting-strips 13 .can be .placed upon brackets 15, which are secured to and depend from the cross-pieces 12. I have shownthese positions of the strips 13 Inthe foregoing description I have shown TOO IIO

advantages thereof, and I therefore reserve the right to make such changes as fairly fall within the scope of my invention.

Having thus fully described my invention, what I therefore claim as new, and desire to secure by Letters Patent, is-

l. A device of the character described comprising a suitably-supported frame, a rotatable device upon the frame, an arm extending therefrom, a prop pivoted to the arm and adapted to normally hold the same against downward movement, and liexible swing-like portions extending in opposite directions from the rotatable device and adapted to be partly wound thereon.

2. A device of the character described cornprising a suitably-supported frame, a rotatable device thereon having annular grooves, supporting pulleys in alinement with the grooves and upon the frame, an arm extending from the rotatable device, a prop pivoted thereto and adapted to normally hold the arm against downward movement, and oppositelyextending swing-like portions secured to the rotatable device and supported by the pulleys,

said swing-like portions being adapted to be partly wound on the rotatable device.

3. ln a device of the character describedv the combination with a suitably-supported frainc having brackets depending therefrom; of a rotatable shaft on the frame, grooved wheels secured thereto, pulleys upon the frame and alining with the wheels, icxible devices extending in opposite directionsfrom thc wheels and supported by the pulleys` and supporting-strips connecting the iiexible devices to form swing-like structures adapted to engage and be supported in raised position bythe brackets.

In testimony whereof 1 have signed my naine to this specification in the presence of two subscribing witnesses.
