WAGON-BODY RAISERr SPECIFICATION forming part of Letters Patent No. 651,520, dated June 12, 1900.

Application filed January 31, 1900. Serial No. 3,535. (No model;) I i To o whom it may concern:

Be it known that I, JosIAH StBAvs, a citizen of the United States, residing at Moweaqua, in the county of Shelby and State of Illinois, have invented a new and useful Wagon- BodyRaiser, of which the following is a specification.

This invention relates to devices for rais ing the bodies of wagons from the runninggears, the object of the invention being to provide a construction in which the wagon may be moved between parts of the device and continued movement of the wagon will act to operate the raiser to lift the body from the gears.

In the drawings forming a portion of this specification, and in which similar numerals of reference designate like and corresponding parts in the several views, Figure 1 is a perspective view showing the raiser with the parts in position to hold the wagon-body elevated. Fig. 2 is a side elevation showing the raiser in its lowered position and the position of a wagon at the moment of engagementwith the raiser to operate it. Fig. 3 is a view similar to Fig. 2 and showing the position of the raiser with the wagon-body elevated andthe wagon partly removed therefrom. Fig. 4 is a detail perspective View showing one of the stop-plates.

Referring now to the drawings, the device of the present invention includes a base comprising parallel sills 5 and 6 and cross-braces 7 and 8. Upon each sill are fixed two vertical uprights 9 and 10 of equal height and having a rail 11 mounted upon their upper ends and parallel with the sill. A link 12 is disposed at each side of the upright 9 and has its lower end pivotally mounted upon a bolt 13, these links being all of the same length. Similar links 14 are pivotally mounted upon the upright 10, and between the up per ends of the elements of each pair of links 12 and 14 is pivoted a beam 15, the ends of which extend beyond the links, and which beam is adapted tolie upon the rail 11 at one limit of the pivotal movement of-the links and to lie above and parallel with the rail at the opposite limit of movement of the links, stops 16 being provided upon the rail to determine the last-named limit of movement. It will thus be seen that the beams 15, which are carried by the sills 5 and 6,may be inde-v 'pendently operated to assume either of the positions shown in Figs. 2 and 3 of the drawmgs.

Movable stops in the form of plates 20 are connected with the beams 15 at one end and upon the inner faces thereof, each of these stops being in the form of a plate having a longitudinal slot 21, in one wall of which and at one end of the slot is a recess 22. Y These plates are connected with the beams through the medium of bolts 23, which are passed through the slots 21 and into the beams, and upon these bolts the plates are slidable and are adapted forpivotal movement. These plates when in their operative positions project above the beams 15, and to cause them to assume these positions they are drawn upwardly until the bolts 23 strike the lower ends of the slots 21, and their upper ends are then rocked in the direction of the adjacent extremities of their respective beams to rest against stop-pins 24 and to cause the lower ends of the plates to swing rearwardly and engage the bolts with the recesses 22. When the plates have been moved to this position, the nuts 25 upon the bolts 23 may be tightened, if desired, to insure against dislodgment of the plates, al though it has been found that under ordinary circumstances the engagement of the bolts 23 with the recesses 22 is sufficient for the purpose.

The present structure is adapted principally for lifting the hay-bodies from the bolsters of the gears, and in practice the wagon is driven between the sills 5 and 6 to move along the sills in the direction of the ends adjacent the stop-plates 20, it being of course understood that the stop-plates have been previously moved to their operative positions, as illustrated. When the body has reached the proper position above the beams 15, the forward end of the body strikes against the stop-plates 20 and continued movement of the wagon causes the body to press against the stop-plates and move the links 12 and 14 upon their pivots, the momentum given to the body being sufficient to cause it to move the beams 15 andcarry the links over their dead-centers to rest against the stops 16. As the gears are further moved they pass from the apparatus, leaving the body in the raised position upon the beams 15. At any subsequent time the gears may be moved to their proper positions below the body, and the beams may be lowered to replace the body upon the bolsters.

It will of course be understood that in practice the proportions shown may be varied and various changes in the details of the structure may be made and also that anysuitable materials may be employed for the several parts without departing from the spirit of the invention.

What is claimed is In adevice of the class described, the combin ation with uprights, of links pivoted thereto, beams pivoted to the links and adapted for movement therewith to lie at different elevations, stops adapted to hold the links at opposite sides of their centers of gravity, and stops adjustably mounted upon the beams and adapted for engagement by a body to be raised, each of said stops upon the beams comprising a plate having a longitudinal slot and a communicating recess, and apivot-bolt passed through the slot and beam, said plates being adapted for movement to cause the bolt to travel in the slots and move into and out of the recesses. V

In testimony that I claim' the foregoing as my own I have hereto affixed my signature in 30 the presence of two witnesses.
