Letters Patent No. 114,173, dated April 25, 1871.

iiPROVEivlENT IN DUMPlNG-WAGONS.

The Schedule referred to in these Letters Patent and making part of the same.

This invention relates to four-wheeled-dumpingwagons constructed to discharge the load at the rear,

in which the body oscillates on an axis located between the wheels, and in which the rea-r axle is cranked to admit ofthe tilting of the body.

Our improvement consists in the arrangement of the cranked portion of the rear axle, which `is turned to stand at an angle of about forty-five degrees to a vertical line drawn through the axis of its journals, for the purpose ofjenabling it to pass over all ordinary obstructions in the road Without necessitating the uudue elongation of the crank, which results if the axle be turned up to a horizontal position, as in the latter case such axle must extend forward at leastA to the point where the body is pivoted.

' To enable those skilled in the art to make `and use our invention, we will proceed to describe its construction and operation.

The frameA of the wagon is mounted upon four wheels, the front ones of which are suciently small to be turned under it, the frame at this end being attached to the front axle by means of holsters and the ordinary fifth-wheel, in the manner shown.

At A', between the front and rear axle, the frame hasa stout cross-bar, which, together with the bolsters at the front end, form support for the'body B of the wagon when in the position shown in fig. 1 in full lines.

The frame in rear of the cross-bar A has no trans verse beams to permit the body toV tilt between its sides.

The body B is hinged upon a stout transverse bolt or shaft, B', arranged in the frame directly in rear of the cross-bar A', where its weight, when loaded, is about balanced.

'To prevent the Vunseasonable tilting of the body its forward end carries a hook, la, by which it may be secured to a staple, l1', on the bolsters. dinary devices may, however, be used for this purpose.

To clear the body in dumping the load the rea-r axle C is cranked and turned forward until its cranked portion stands at an angle of forty-live degrees, -more or less, to a vertical line drawn through the axis of its journals. In this position ,it is firmly secured by braces C to the frame.

We do not claim broadly a cranked rear axle in fourwheeled dumping-wagons, as cranked axles haveV been employed in this connection. But, in all cases, such cranked axle has been arranged either to hang down vertically or in a horizontal position. The former arrangement isV objectionable, because the axle hangs down too low, coming so near to the surface of' the road that it will not clear ordinary obstructions, while the latter arrangement requires that the axle should be cranked far enough to extendforward to the point where the body is hinged, thus making the crank undulyA long, and, consequently, weakening the axle. By our arrangement these objections are all overcome.

What we claim as our invention, and desire to secure by Letters Patent, is`

In a four-wheeled dumping-wagon, the cranked rear axle C, but only when its cranked portion is turned forward to stand about midway between a horizontal and Vertical position, in the manner and for the purpose shown and described.
