Patented Oct. 20, 1931 UNITED STATES PATENT OFFICE NOEL D. VETI-I, OF BARNESVILLE, OHIO, ASSIGNOR TO THE WATT CAR AND WHEEL 00., OF BABNESVILLE, OHIO, A CORPORATION OF OHIO MINE CAB,

Application filed December 9, 1929. Serial No. 412,873.

This invention relates to industrial cars such as mine, ore, and quarry cars.

In the usage of cars of these types, one of the prime requisites is that the car have a minimum over-all height, but, at the same time, a maximum capacity, without undue lateral dimensions. Various efforts have been put forth in the past to secure a car of maximum capacity without increasing what is generally looked upon as the minimum over all height, and the principal objective of the present invention is the accomplishment of this result.

A further object of the invention is the provision of a car having a fiat central bottom portion and upwardly sloping side bottom portions and an axle that will function as a stiifener for said central portion of the bottom and a considerable portion of said sloping portions thereof.

A still further object is the production of a car body whose bottom is formed of metal plates fastened directly to the wheel axles, the fastening elements for attachingthe car bottom to the axles also extending through the main sills of the car body, these main sills, in the preferred embodiment, being formed of channel irons. By having the sills and car bottom plates attached directly to the axles and, as contemplated by the present invention, having the draw bar or tie rod also fastened to the bottom plates, all shocks imposed upon the cars at the endsthereof, either when brought into contact with one an other or when the cars are being pulled, will be transmitted from one end of the car to the other by main beams and draw bar. Furthermore, by having the tie rod or draw bar rigidly attached to the bottom plates, and the bottom plates directly attached to the axles, all

the stress set up by the car being pulled is distributed equally to both of the axles,

A further object is the construction of a bumper composed of a bumper block secured directly to one of thebottom plates, said block being protected by a bumper plate that extends from the top thereof and beneath the bottom plate of the car, with the end of the tie rod or draw bar interposed between said plate and the bumper block.

With these and other objects in view, the invention consists in certain details of construction and combinations and arrangementsofparts, all as will hereinafter be more fully described and the novel features thereof particularly pointed out in the appended aims- In the accompanying drawings, illustrating the preferred embodiment of the present invention in a mine. car,

Figure 1 is a top plan view;

Figure 2 is a longitudinal, vertical, central section of the car illustrated in Figure 1;

Figure 3 is a transverse, vertical, sectional view, on the line indicated at 33 inFigure 1; and s Figure 4 is a detail sectional view on the line H of Figure 3.

While the design of the car body proper maybe varied, it is preferably formed of a substantially flat central body portion 10 and side bottom portions 11, which extend upwardly from the center portion 10 and have attached to their outer extremities, sides 12. At one end, the car is provided with a substantially rigid end 13, while the opposite end is constituted by a gate, preferably in the form of a U-shaped bail member 14, pivoted at 15, between bail ears 16 and the sides 12 of the car. In accordance with the present invention, this body is supported on a pair of axles,.each of which has a central portion 18 and upwardly offset portions 19 near the ends thereof, the. ends 20 of the axles forming journalsof the wheels 21. As shown in Figures 2 and 4, these axles have fiat, upper surfaces, preferably angular in cross section, and the metal plates constituting the central portion 10 andthe sloping side portions 11 of the car bottom rest directly on the flat'upper surfaces of the axles. In other words, the central portion 10 of the car bottom rests on the flat straight central portion 18 of the axles, and the inclination of the side portions 11 of said bottom correspond to the inclination of the offset portions 19 of the axles. As a consequence, when these bottom plates of the car bottom are firmly attached to the axles, as will be hereinafter described, there is produced a substantially rigid unitary construction which includes the main sills of the car, as will also be later described. For instance, the car body is attached to the axles by clips 22, which embrace said axles shown in Figure 4, the clips being provided with flanges 23 through which fastening elements such as bolts 24 extend. These fastening elements not only pass through flanges 23 of the clips, but they also extend through the sloping portions of the car bottom and the sills of the car, said sills preferably taking the form of channel irons 25. whose webs lie flat against the surfaces of the sloping side portions 11 with the flanges projecting upwardly. These 1 sills, of course, extend the full length of the car at each side of the longitudinal center of the car, and extending longitudinally and centrally of the car bottom is the tie rod or draw bar 26 rigidly attached to the bottom plate 10 by suitable fastening elements preferably in the form of rivets, some of which extendthrough the draw bar, bottom 10, and binder straps 27. Such a construction resents a very rigid unitary car body, in w iich the strains are taken up by the tie rod and sills and in which all stress, when the car is being pulled, is distributed equally to both of the axles.

At each end of the car, there is a bumper block 28 mounted directly on the bottom plate 10, the draw bar being formed with inclined portions near each end so that its ends overlap the upper surfaces of said blocks. For protecting the upper surface of said block 28 and the overlapping end of tie rod 26, is a. bumper plate 29 which extends from the top surface of the block downwardly and under the bottom plate 10, as well as the end binder stra 27. Attached to the draw bar 26 near eac end thereof is a relatively heavy coupling bar 31 which projects over the bumper plate 29, being held in vertically spaced relation thereto by spacer blocks 30, disposed laterally on the upper surface of the bumper plate. These several parts, i. e. the bars 31, spacer blocks 30, bumper plate 29, bumper block 28, bottom plate 10. and binder strap 27 are all rigidly connected together by through bolts 32 that project through all of these elements. As will be understood, the spaces provided between the bumper plates 29 and the relatively heavy bars 31 are for coupling links adapted to be engaged by coupling pins removably positioned in suitable openings in the bumper.

To facilitate discharge of the contents of the car from the gate end thereof when the car is dumped, and to protect the bumper blocks 28, the gate end of the car bottom, or rather the bumper block 28, is provided on its upper surface with inclined plates 33. It will be understood, of course, that the sloping side portions 11 of the car body are not sufiiciently high to provide the clearance necessary for the wheels. In accordance with the usual practice, therefore, portions of these sloping sides are cut away and the openings thus formed closed by housin 34, which project upwardly somewhat into the interior of the car.

What is claimed is:

1. In a mine car and the like, a pair of axles having substantially flat upper surfaces and upwardly offset end portions, wheels journaled on said axles, and a car body mounted on said axles, said body having a central bottom plate supported on the flat upper surfaces of the intermediate portions of said axles and sloping side portions supported directly on the offset end portions of said axles.

2. In a mine car and the like, a pair of axles having upwardly ofi'set end portions, wheels on said axles, a car body having a flat central portion and sloping side portions, the inclination of said side portions corresponding to that of the offset portions of the axles, sills extending longitudinally of said sloping portions of the bottom, and means for rigidly securing the sloping portions of the bottom and axles to said sills.

3. In a mine car and the like, a pair of axles having upwardly offset end portions, wheels on said axles, a car body having a fiat central portion and sloping side portions, the inclination of said side portions corresponding to that of the offset portions of the axles, sills extending longitudinally of said sloping portions of the bottom, clips embracing the offset portions of said axles, and fastenin ele ments extending through said clips, said sills and the sloping portions of the car bottom.

4. In a mine car and the like, a pair of axles having upwardly offset end portions, wheels on said axles, a car body having a flat central portion and sloping side portions, the inclination of said side portions corresponding to that of the offset portions of the axles, channel irons extending longitudinally of the sloping portions of said bottom with their webs flat against the upper surfaces of said portions, clips embracing the offset portions of said axles, and fastening elements extending through said clips, the sloping portions of said bottom, and the webs of said channel irons.

5. In a mine car and the like, a pair of axles having flat upper surfaces and upwardly offset end portions, wheels on said end portions, a car body having a flat central bottom portion fastened directly to the intermediate portions of said axles and sloping side bottom portions attached directly to the offset portions of said axles, bumper blocks on 5 said central bottom portion at the ends thereof, bumper plates secured to said blocks and the car bottom, a draw bar secured to said bottom with its ends interposed between said bumper blocks and bumper plates, coupling 10 Jars projecting over each bumper plate, spacer members between each plate and coupling bar, and bolts extending through the coupling bar, bumper plate, bumper and car bottom at each end of the car body.
