DUMP-CAR.

resents.

To all whom it may concern:

Be itknown that I, KARL H. HANSEN, a subject of the Emperor of Germany, and resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have 1nvented a new and useful Improvement in Dump-Cars; and it do hereby declare the following to be a full, clear, and exact dcscription thereof.

My invention relates to dumpcars. Cars of this type are employed either to make fills by being dumped from a trestle, or to dump on level ground for light grading work. When these cars are dumped from a trestle it is necessary to have a stable car which will have the least possible tendency to tip over and derail when dumping. On cars of this class where the body goes over to one side with considerable force the momentum of the mass of both the body and its load is very great and is sometimes suflicient to lift the whole car and body, so that they are precipitated over the trestle, often with the resulting loss not only of property, but sometimes of life.

The object of my invention is to combine in one car a body which is capable of throwing the load to a farther distance from the rails where it is being used on level ground than where employed on a trestle, so that contractors who are without factory facilities on their different jobs can easily and quickly alter these cars to suit two distinctly different conditions.

To these ends my invention comprises the novel features hereinafter set forth and claimed.

In the accompanying drawings, Figure 1 is a view showing the arrangement to throw the material far away from the track, the dumping position being indicated for level ground work, as well as the dumping position when the car is employed for trestle work. Fig. 2 is an enlarged view of a portion of the car showing the dumping mechanism in position to discharge the material. at a distance from the tracks, the dumping position being indicated in dotted lines to the right, and the dumping position of the U car to the left in dotted lines where employed for trestlework; and Fig. 3 is a ver tical section. showing the car in position for trestle-work.

1n the drawing, the numeral 2 designates 5 a suitable truck supported by the wheels 3.

Specification of Letters Patent.

Application filed January 11, 1913.

Patented'Jan. 13,1914. Serial No. 41,595.

The truck supports the castings 1 which are secured in any suitable manner to the truckbody. The casting 1- is provided with the base 5 which has the central depression 6 and the seats 7 at each end thereof formed by said base and the side portions 8. The uprights 9 have the open bearings 10 adapted to support the pin 11 when the car-body 12 is in its elevated position for trestleworlt. The outlets of the bearings 10 are sufficiently wide to permit of the lifting of the car-body straight up to withdraw the pin 11 from the seat 10, while at the same time the horns 13 formed in said seat prevent the body from accidentally jumping from the frame when dumping as said pin will come in engagen'ient with said horns and hold back on said pin.

The car-body casting 14- or rocking memher is secured to the sills 15 of the car-body and said casting is adapted to fit down within the casting lVhere the car is to be employed on level ground the bearing portion 16 at the extreme lower end of the casting 14- rests in the depression 6 in the base of the casting 4c. Extending outwardly from both sides of the bearing portion 16 are the rounded portions 17 which are adapted to enter the seats 7 when the car-body is dumped indicated at the right of Fig. 2 in dotted lines. The body-casting 14 is further provided with the hub-portion 18 with the opening 19 formed therein and through which the pin 11 is adapted to pass, as indicated in Fig. 3 when the car body is elevated for trestle-work, and the dumping position of the car when so adjusted is indicated to the left in Fig. 2 in dotted lines.

Chains 20 are provided for connecting the car-body with the truck to prevent the tilting of the car in transit.

In Fig. l I have illustrated the car-body in both positions, the full lines indicating the position of the car when arranged for work on level ground, and the dotted lines indicating its position where elevated for trestle-work. For convenience I have used the terms Low and High on the drawing to clearly indicate these positions. In the same way these words have been used on the drawing to illustrate the positions of the car-body in dumping both at high and low positions. Where the car is to be used on level ground, the rocking-member 14 will rest with its bearing portion 16 in the depression 6, and when the car is dumped the body will take the position indicated in Fig. 1, while at the same time the rocking-member will assume the position indicated in Fig. 2 at the right thereof in dotted lines. If, however, the car is to be used for trestle-work, the body will be lifted until the opening 19 coincides with the open bearings 10, whereupon the pin 11 will be inserted and the car body will be supported at high position. In dumping in this high position thecar will take the position indicated in Fig. 1, while the rock ing-member will assume the position indicated in dotted lines at the left of Fig. 2, and the car-body will not throw the material at such a distance from the tracks which is not necessary at such a distance from the tracks which is not necessary or so desirable in trestle-work, while at the same time the danger of the car-body, as well as the trucks being precipitated over the trestle, are practically eliminated.

By my invention, I obtain all the advantages of the use of the dump-cars of the rocker type with the pivotal point arranged to move sidewise from the center line of the car to give the car-body a large side throw, while at the same time the car can be quickly transformed into a dump car dumping from a pivotal point at a higher level, where the stability of the can/body is assured and at the same time all the requisite side throw for trestle-work is obtained.

l/Vhat I claim is:

1. In a dump-car, the combination with the truck, of a rocker'frame supported thereby, a car-body, a rocking-member on said car-body adapted to rest on said rocker" frame, said rocking-member having a pivotopening therein, and a bearing supported by said truck above said opening in said rockerframe, whereby when said rocking member is lifted said pivot-opening is brought into register with said bearing for the insertion of a pin.

2. In a dump-car, the combination with a suitable truck, of a rocker-frame supported thereby, a rocking-member carried by the car-body adapted to engage said rockerframe, said rocking-member having a pivotopening therein to receive a pivotal pin, and an open top bearing above said opening and supported by said truck, whereby when said rocking-member is lifted said pivot-opening is brought into register with said bearing to be supported by a pin inserted in said opening and bearin In testimony whereof, I the said KARL H. HANSEN have hereunto set my hand.
