MAX ORENSTEIN. OF BERLIN, GERMANY.

DUMPING-CAR.

Specification of Letters Patent.

Patented Dec. 1, 1908.

Application filed May 18, 1908. Serial No. 433,481.

To all whom it may concern:

Be'it known that I, MAX ORENSTEIN, a

citizen of the German Empire, residing at conveyance of sand, earth, stones and the.

like, the bodies of the various cars must be tipped in succession by hand.

The subject of my invention is a'contriv ance by means of which the work requisite for tilting the car-bodies is performed by the locomotive employed to draw the train of cars, the bodies of all the latter being tipped automatically during running of the train.

The accompanying drawing, by way of example, shows the invention applied to dumping-cars tilting to one side only.

Figure 1 is a side elevation of a box-bodied dumping-car. Fig. 2 is a front elevation and part section thereof. Fig. 3 is a side elevation of a modification. Fig. 4 is a front elevation thereof. Fig. 5 shows the tiltinglevei" alone.

, The car itself, with its body, may be of any well-known construction and shape.

The lmprovement consists ineach car being furnished with coupling-parts, by means ofwhich the car-body can be coupled with one of the running-wheels of the car (or with a wheel, lever, or the like, actuated by a running-wheel), and by means of which,

after coupling has been effected, a moment of torsion sufficient for tilting the car-body is transmitted to "the latter by push or pull.

In the car shown in Figs. 1 and 2 a tiltinglever b is secured by means of a cross-joint c to the bed of the body at on the side opposite to that at which the contents are dumped. Ordinarily the lever 12 is held outof use in the horizontal, dotted-line position shown in Fig. 1 by n cans of a suitable catch 0. To the free end of the lever b there is jointed a pin f. In the wheel a a number of holes 9 are drilled or otherwise provided at equal distances apart, into which the pin f fits. The length of the lever b is such that when the body is in its non-tilted position the in f can be inserted into that hole 9 whic for the time being is the lowermost.

As each car in succession arrives at the place of dumping, the body at and wheel a must be coupled by the lever b as described. If now the train of cars is drawn forward, or pushed backward, by the locomotive, then on the wheel a of each car after cou ling making half a rotation, the body (I Wll be tilted with positive motion into thedottedline position shown in Fig. 2. If the train of cars is drawn through a distance represented by more than half a rotation of the wheel, for instance, by several rotations, the body will not only be tilted forward, but will be tilted I back again into the normal position, or will be tilted to and fro several lLlIIIBS, whereby a better guarantee is offered for complete dumping of the contents of the car.

Between the coupling-parts there may be a suitable amount of play left, so that the body (1, when once lifted beyond its position 'of unstable equilibrium, can drop lnto the end position by gravity.

Instead of connecting the body cl with the bottom of the wheel a by means of a member exerting a push (tilting-lever b) on the side opposite to that at which the material is dumped, the body (1 may be connected with the top of the wheel on the dum ing side itself. In this event the tilting is one by a ull instead of a push. If in such case there is employed to connect the body (Z and the wheel a a member '(for example a chain) which can only be used to exert a pull, but not a push, then the car-body will only be tilted forward, but not backward again, so that tilting to and fro cannot be effected.

In the modification shown in Figs. 3 and 4 the body d is not connected with a wheel a direct, but with a disk m presenting holes Z and driven by one of the wheels (I, by means of suitable gear, such as toothed wheels 71,, i, Tl

It, or chains.

Having thus described my invention, I claim as new:

1. In a dumping car, a frame, car wheels upon which said frame is mounted, a trans- Vorscl y tilting body pivoted to the frame, and a bar connecting the tilting body with one of the car Wheels where by rotationof the wheels in either direction will tilt and afterwards return the body to its normal position.

2. In a dumping car, a frame, oar wheel's upon which said frame is mounted, a transversely tilting bod y'pivoted to the frame, and

direct connections between the tilting body and one of the car wheels whereby rotation .l. l (i ver whose upper end is ointod to one side of of the wheels in either direction will tilt and afterwards return the body to its normal position. I

3. In a dumping car, a frame, car Wheels upon which said frame is mounted, a transversely tilting body pivoted to the frame; and non-flexible connections between the by rotation of the wheels in either direction its normal position.

4. In 3, dumping-our, a tilting body and car wheels on which it Is mounted, and a le- E tachably 1 wheels wi gposition, whereby on rotation of the said 5 wheel the lever is raisedend tilts the car body automatically, substantially as de- 20 i scribed.

tilting body and one of the emwheels where 5 l the said body and whose lower end can be de- 15 ointed to a point on one of the can ien such point is in its lowermost In witness whereof I have hereunto set my 5 hand in presence of two witnesses. wlll all; and afterwards return the. body to MAX ()RENSTEIN.
