To all whom it may concern:

Be it known that We, EMILE CHEVALIER and LOUIS BUETTE, citizens of the French Republic, residing at Paris, in said Republic, have .invented a new and useful Dumping Freight-Gar, (for which we have obtained Letters Patent as follows: in France September 16, 1888, No. 194,142; in England April 11, 1888, No. 6,206; in Germany December 8, 1888, No. 47,982; in Belgium April 17, 1889, No. 85,996; in Italy May 3, 1889, No. 25,370; in Austria-Hungary May 17, 1889, No. (3,422 and No. 18,871; in Spain. July 2, 1889, No. 7,782, and in Switzerland June 20, 1889, No. 1,142,) of which the following is a full, clear, and exact description.

Our invention has for its object a new car for the transportation of earth, ballast, minerals, coal, and merchandise or products which are shipped in bulk, which is built in such a manner that it can at pleasure be dumped to the right or to the left side, forward or backward, under the action of compressed air, of

water or steam under pressure, operating in a system of cylinders suitably arranged for this purpose or by creating a more or less perfect vacuum in these cylinders. WVe attain these objects by the mechanism illustrated in the accompanying drawings, representing a car of our system of standard gage, which can be dumped to both sides, and in which- Figure 1 shows aside view of the car. Fig. 2 shows a plan view of the same, the body of the car partly removed; and Fig. 3 shows an end view of the same car.

Similar letters refer to similar parts throughout the several views.

Our new system of car comprises a frame X, symmetric with regard to the axis of the road and supporting the six cylinders A, arranged three on each side of the longitudinal axis of the car, so as to dump the body of the car to the right or to the left side. These cylinders oscillate on trunnions B, arranged on the cross-beams G of the frame, and are provided to this effect with saddleshaped bearings 0, formed in one with the cylinder and which are open at their lower end, so as to allow of the cylinders being lifted off, if required, while at the same time sand or dust is prevented from entering between the moving parts. Thecompressed air furnished by the machine is conveyed either directly or through intermediate reservoirs into the cylinders under the pistons, which operate always in the same direction upward, in order to cause the lifting of the body of the car on one side, while the lowering is automatically performed as soon as the exhaust for compressed air is brought in communication with the atmosphere.

In the drawings the axis of rotation D of the body of the car coincides with the axis D of the joint of the piston-rods, so that the pistons which are not in operation are subj ected to no strain and remain motionless. This coincidence, however, is not strictly nee essary. In some cases it may, on the contrary, be desirable that the two series of axes be independent from each other. In this case the two series of pistons are compressed in the movement of the body of the car. We

could even, keeping the joint axes D separate, combine the two axes of rotation D, and in this case the body of the car can be balanced on this axis. In the same manner the joint axes D may be united in one common axis, thereby preserving one or two rotationaxes D.

a In our drawings the action of the air is only exercised on one side of each piston; but the compressed air, or the water or steam under pressure, or the vacuum can be admitted to alternately act on the two sides, if so desired.

The frame X of the car can be constructed in any suitable manner, and its only special feature is the necessary arrangement for the reception of the cylinders and that which al lows the oscillation of the cylinders and the swinging movement of the body of the car.

The metallic body Y of the car, of any suitable form, rests on this frame and is provided at its bottom with two longitudinal sleepers E, made of .I-iron, to which are attached slidguides Gr, having for their purpose to prevent any longitudinal movement of the body. The collars I are attached to the sills II of the frame.

The doors V are arranged so as to open and close automatically. For this purpose theyclosed again. In order to make sure that the.

(1001' comes by its own weight exactly back in its original position and will be surely closed, the rotation-axis L of the hinges is placed slightly inward to the car. This axis can, as shown in the drawings, be placed higher to facilitate the discharge of large pieces, but can be placed at any suitable height.

\Ve wish it distinctly understood that the arrangement heretofore described can be applied just as well 011 a car with a wooden box.

The compressed air contained in one or more intermediate reservoirs is conveyed in the general conduit M at the moment of the discharge of the car. On this general conduit are branched side pipes N and N for the purpose of distributing the air at pleasure to the right or to the left side by means of a threeway cock P, placed under every car and manipulated by means of a handle P. This arrangement enables us, when the opening of the cooks is regulated, to dump all the cars of a train or only a part of them either to the rightor to the left side, as the case may be, as the compressed air only travels through the general conduit of those cars which are not to be dumped. IVhen the discharge is completed, it is sufficient to bring the general conduit in communication with the atmosphere, and the bodies of the cars will by. their own weight come back into their normal position.

In case the nature of the work which is being executed should allow this, all the cars of a train may be dumped at the same time to the right or to the left side, as the case may be. In this case it will be desirable to substitutc for the air-distribu ting system which we have just described-two separate conduits running over the entire length of the train,

one supplying the cylinders placed at the right-hand side and the other the cylinders placed at the left-hand side. The discharge is then effected by the engineer by means of a valve place in his reach, and the intermediate cocks P might be dispensed with.

The drawings show the application of our system on a car of standard gage; but we wish it distinctly understood that it can be applied to cars of any gage.

Having fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. In an apparatus-for dumping cars, the combination,with the truck-frame having pivotal bearings on each side of the middle of the frame, of cylinders 011 each side of the frame, mounted on said bearings and provided with pistons and piston-rods, and a car-body pivotally mounted upon the upper ends of said piston-rods, whereby said rods upon one side of the car furnish the bearings when the rods on the other side are acting to lift the body, substantially as set forth.

2. In an apparatus for dumping cars, the combination, with the frame, of cylinders for compressed air, steam, or water, said cylinders being mounted on trunnions and provided with saddle-shaped bearings and open at one end to permit of the cylinders being lifted off, substantially as setforth.

8. In a dumping-car, the herein-described door, consisting of the combination, with the door proper and the hinges J, whose axis of rotation is placed inward to the car, of an oscillating elbow-lever provided with a horizontal arm having a catch and with an upright arm which at the dumping of the car abuts against the side of the frame of the car, thus causing the said catch to be raised and allow the door to open by its own weight, substantially as set forth.

In witness whereof we have hereunto set our hands in presence of two witnesses.
