JONATHAN M. FUHRMAN, OF ALESIA, MARYLAND.

HAYn RACK.

SPECIFICATION forming part of Letters Patent No. 547,067, dated October 1, 1895.

Application filed March 8, 1895.

To @ZZ whom it may concern.-

Beit known that I, JONATHAN M. FUHRMAN, a citizen of the United States, residing at Alesia, in the county of Carroll and State of Maryland, have invented a new and useful Vehicle, of which the following is a specification.

The invention relates to improvements in vehicles.

The object of the present invention is to improve the construction of vehicles, such as hay-wagons and the like, and to enable the body to be tilted or canted laterally to either side in order that the body may be maintained in a horizontal position in ascending and descending a hill to prevent a vehicle from upsetting.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure l is a perspective view of a hay-wagon constructed in accordance with this invention. Fig. 2 is a central longitudinal sectional view. Fig. 3 is a transverse sectional view. Fig. 4 is a rear elevation showing the running-gear in an inclined position and the body or rack arranged horizontally.

Like numerals of reference indicate corresponding parts in all the figures of the drawings.

l designates the body or rack ofa hay-wagon, which body or rack may be of any desired construction and which is mounted on suitable running-gear 2, and it is provided at its front and rear with transverse bars or crosspieces, which are centrally fulcru med on transverse bolsters or bars 4. The transverse bolsters 4 and the cross-pieces 3 are provided with central tapered enlargements 5 and. The enlargement 6 of the bolster 4 is located at the upper edge thereof, and the enlargement 5 of the cross-piece 3 is arranged at the lower edge of the same,whereby a fulcrum or bearing is provided to permit the body or rack to tilt laterally, the enlargements offsetting the body portions of the cross-pieces and the bolsters sufficiently to permit the side beams or sills of the body or rack to pieces and the bolsters Serial No. 540,981. (No model.)

have free play at either side of the vehicle. The bolsters and cross-pieces are provided at opposite sides with leaf-plates 7, having registering perforations and receiving a longitudinally-disposed shaft 8, which extends from one bolster to the other and terminates at the rear end of the vehicle in a crank-handle 9. The longitudinally-disposed shaft hinges the body or rack to the bolsters 4, which are mounted on the running-gear, and the shaft carries worms l0, located adjacent to the crossand meshing with gear Wheels or pinions 11 of transverse shafts l2, whereby when the longitudinally-disposed shaft is turned the transverse shafts will be simultaneously rotated. The transverse shafts 12 are journaled in suitable bearings of the bolsters and are connected with the body or rack at opposite sides thereof by chains 13, which are oppositely Wound around the transverse shafts between inner and outer bearings 14 and 15, whereby When the longitudinal shaft is rotated one chain of each transverse shaft will be Wound up and the other un- Wound to tilt or cant the rack or body. Vhen the longitudinal shaft is turned to the right, the right-hand chain of each shaft l2 is wound up and the body or rack is tilted to the right, and the reverse operation takes place when the operating-shaft is turned to the left. The upper terminal-s of the chains may be attached to any suitable portion of the body or rack, but are preferably attached to the crosspieces 3.

The rear bolster 4 is preferably connected with the running-gear by standards in order to be removable, and the front bolster is provided with a central socket to receive the king-bolt or pivot of the front axle.

It Will be seen that the mechanism for tilting the body or rack may be readily applied to all kinds of vehicles, that it is especially adapted for hay-wagons and other vehicles which are loaded to a considerable height and which are apt to become top-heavy, and that it is capable of enabling such a load to be readily tilted or canted to either side to maintain the load perpendicular and to prevent the same from upsetting.

Changes in the form, proportion, and the minor details of construction may be resorted to Without departing from the principle or sacrificing any of the advantages of this invention.

That I claim is- 1. The combination with a running gear, a tilting hay rack frame mounted thereon, the front and rear transverse shafts journaled in suitable bearings and arranged adjacent to the front and rear axles, flexible connections oppositely wound around the transverse shafts and attached to the hay rack frame, pinions mounted on the transverse shaft, and a centrally arranged longitudinally disposed shaft extending from the front to the rear axle and forming a pintle for hinging the frame to the running gear and provided with a pair of worms meshing with the pinions, substantially as and for the purpose described.

2. The combination of transverse bolsters having central enlargements, a body having cross-pieces provided with similar enlargements, leaf plates or bearings mounted on thel cross-pieces and bolsters and having registering openings, a longitudinal shaft arranged in said openings and hinging the body to the 25 bolsters, transverse shafts journaled on the bolsters and provided With centrally arranged pinions, flexible connections oppositely wound around the transverse shafts and connected with the body, longitudinal shaft and meshing with the pinions, substantially as described.

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

JONATHAN M. FUI'IRMAN.
