ORE-CAR.

$PECIFICATION forming part of Letters Patent No. 512,17 3, dated January 2, 1894.

Application filed April 3, l 893.

To all whom 232? may concern:

' Beit known that we, MICHAEL C. ENSMINGER and JOHN W. SMITHAM, citizens of the United States of America, residing at Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Ore-Oars; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figfigures of reference marked thereon, which form a part of this specification.

Our invention relates to improvements in ore cars, and the object of the improvement is to provide a car of this class whose end door shall open automatically as soon as the car body is lifted to a suitable inclination, and automatically return to the locking position when the car body again assumes the horizontal.

To this end the improvement consists of the features hereinafter described and claimed, all of which will be fully understood by reference to the accompanying drawings, in which is illustrated an embodiment thereof.

In the drawings, Figure 1 is a side elevation of the car, the dumping position of the body being indicated in dotted lines. Fig. 2 is a front end view of the same. Fig. 3 is a top or plan View of the platform,the car body being removed. Fig. 4 is a detail view of the means forlocking the car bodyin the upright position.

Similar reference characters indicating corresponding parts or elements of the mechanism in the several views, let the numeral 5 designate the car body pivoted forward of its center of gravity, to the platform 6 which is mounted on the trucks 7.

As shown in the drawings, the axis of the car consists of the bolts or rivets which pass through the coinciding apertures of counterpart lugs formed on the car body and platform respectively, as indicated at S.

The car is locked in the upright or horizontal position by means of a bell crank-lever 9 located between the rearwardly projecting bars 10 of the frame-work, which approach each other as they extend backward. Lever 9 is fulcrumed at 12. One arm projects up- Serial No. 468.913. on model.)

wardly and is provided with a hook which enters the aperture formed in a depending plate 13 attached to the rear extremity of the car body. The other arm of the lever projects outwardly from the fulcrum, and occupies approximatelya horizontal position. The lever 9 is provided with a short arm 9 which extends inward from the fulcrum and engages the lower extremity of a coil spring 11, whose upper extremity bears against a top plate 15 made fast to the bars 10. This top plate is slotted as shown at 16 to receive the upright arm of the lever and to allow said arm the required movement. The top plate15 is provided with apertu red wings orprojections15 to permit the attachment of the dead chains 26 which are secured to the track. The object of this connection is to prevent the possibility of the cars going over the dump on steep inclines. The door 17 of the car is pivoted at the top by means of a rod 18 which passes through coinciding apertures formed in lugs 17 and 5 respectively with which the door and the sides of the car are provided. The door is provided with lateral projections 1'7 which engage the hooked outer extremities 19 of the arms 19 which are made fast at their inner extremities to the platform 6 by means of bolts or rivets as shown at 19 or in any other suitable manner. These hooked arms lie outside of the vertical planes of the sides of the car body, whereby the latter is allowed to move freely therebetween, as during the operation of dumping and returning to the horizontal position.

To dump the car, the foot is placed upon the outer horizontal arm of the bell-crank lever which is depressed sufficiently to detach the upper arm of the lever from the depending apertured plate. The car body is then unlocked, but as its center of gravity is located to the rear of its axis, it remains in the horizontal position until its equilibrium is destroyed by lifting upon the handle attached to its rear end, when it at once assumes the inclined or dumping position. As soon as the car body has moved a short distance downward, the door 17 is unlocked from the hooked stationary arms 19 and swings outward on its pivot or axis to the vertical position shown by dotted lines in Fig. 1. When the car body is againmoved to the upright position, the

movement of the door is reversed, and it returns to the locked position with its lateral projections engaging the hooks of the lockin g 7 arms.

Having thus described our invention, what we claim is- 1. In an ore car, the combination with the platform suitably mounted, of the car body pivoted on the platform and having one end hinged at the top of the car and provided with lateral projections, and the hooked locking arms rigidly secured to the platform of the car, their hooked extremities being adapted to receive the lateral projections of the door, substantially as described.
