DUMPlNG-CAR.

SPECIFICATION forming part of Letters Patent No. 692,457, dated February 4, 1902. Application filed May 18, 1901. Serial No. 60,859. (No model.)

To all whom it. may concern.-

Be it known that I, GEORGE 1. KING, a citizen of the United States, residing at the city of Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvementin Dumping-Oars, of which the following is a full, clear, and exact description, 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, forming part of this specification, in which- Figure l is a top plan view of my improved dumping-car, part of the body portion being removed to show the underframing. Fig. 2 is a side elevational view, one end of said car being shown in vertical section. Fig. 3 is a detail top plan View showing the door-operating mechanism. Fig. 4 is a sectional view on line 4 4, Fig. 3. Fig. 5 is a sectional view on line 5 5, Fig. 3; and Fig. 6 is adetail view showing the pawl-and-ratchet mechanism for the door-operating shaft.

This invention relates to a new and useful improvement in dumping-cars designed especially for use in hauling coke and other light loose loads, the object being to provide a car with a bottom composed of a plurality' of hoppers, each of which is provided with an exit for the load, said exits being controlled by suitable doors. Another object is to construct a car of the character described of structural steel, and in order to obtain maximum cubic capacity, strength,-and rigidity with the least amount of dead-weight with respect to the carrying capacity of the car I utilize the side walls as plate-girders, which plategirders also partially form what might be termed the top 0 chords of side trusses, the bottom chords of said trusses being preferably inthe form of horizontally-arranged latticed girders supported at their ends by the body-bolsters of the car.

Another object is to take advantage of the arrangement and disposition of the hopperfloor sheets by utilizing said sheets to add strength and rigidity to the structure.

3 indicates the bod y-bolsters,which are preferably continuous from side sill to side sill and I-shaped in section.

4 indicates the side sills, which are preferably in the form of channels with their flanges presented inwardly, said channels being riveted to the ends of the body-bolsters.

5 and 6 are top and bottom cover-plates for the body-bolsters.

7 indicates angles, preferably parallel to each other and extending from bolster tobolster, said angles being preferably on a lower plane than the bottom flanges of the side sill, to which they are connected by lattice-bars 8. The side sills, angles, and lattice-bars form horizontally arranged latticed girders, which in addition to resisting buffing blows and lateral forces are also placed in tension by forming the bottom chords of the side-truss frames.

9 indicates the side walls of the car in the form of plate-girders, which are supported over the body-bolsters by inclined stiffeningbraces 10.

By referring to Figs. 2 and 5 it will be observed that the lower edge of the side sheet is above the side sill and that said side sheet has angles 11 riveted to it, which angles are oppositely inclined or arranged zigzag between the inclined stifieningbra'ces 10.

These angles and inclined stiffening-braces form a series of triangles or A-frames connected together at their upper ends by the side sheet and at their lower ends by the side sill member of the horizontal girder. This structure forms in itself a side truss of great strength, in that part of the top chord or compression member is a deep web in the form of the side sheet or side wall of the car.' The side sill member of the horizontal truss partially forms the bottom chord and under load is placed in tension, while the inclined braces 10 and 11 take the place of the usual vertical posts and diagonals commonly found in trussed structures.

So far as the above construction is concerned it is substantially the same in all resnects as that shown and described in the United States patent granted to King and Jessen, No. 670,614, dated March 26, 1901, with the exception that the body-bolsters in the present case are continuous from side sill to side sill and there are six instead of two inclined angles between the end stiffeningbraces.

12 indicates the sloping end floor-sheets, which at their upper portions are inclined at angles of about thirty degrees, while their lower portions are inclined at angles of about forty-five degrees. The purpose of this difference in inclination is to utilize to the full the available space for the load and at the same time-enable the contents of the car in the bottoms of the hoppers to readily and quickly be discharged, the great inclination of the sloping sheets forming the hopper preventing any choking in the exit for the load.

13 indicates the side hopper-sheets, which are riveted at their upper edges to the bottom edges of the side sheets. These inclined hopper-sheets 13 pass inwardly over the angles 7 and thence downwardly to form the vertical side walls of the exit for the load.

14indicates the side hopper-sheets arranged centrally the car, the upper outer edges of said sheets being riveted to the lower edges of the side sheets 9, while the inner portions of the sheet are bent downwardly over the angles 7 to form vertical walls for the two centrally-located openings for the load.-

15 indicates a short cross-ridge riveted to the lower edges of the hopperplates 14. This cross-ridge is located between and below the plane of the parallel angles 7 and by its angular formation strengthens the inner edges of the hopper-sheets 14, in addition to which it forms a shed for directing the contents of the car through the two centrallylocated exits for the load.

16 indicates cross-ridges, whose apices practically extend across the entire width of the car. The inclined lower edges are riveted to the edges of the side hopper- sheets 13 and 14. The deepest portion of these cross-ridges 16 terminate approximately on the plane of the angles 7, to which they are secured by appropriate fastening devices. These cross-ridges 16 not only serve to support and strengthen the side hopper- sheets 13 and 14, but they also serve to tie the side walls together at points intermediate the body-bolsters, and they likewise tie angles 7 together. In this manner separate and distinct tie-braces may be dispensed with.

The sheets forming the side, end, and hop per walls, as well as the cross-ridges, are cut to the proper shape, suitable marginal flanges being left for the reception of the proper number of securing rivets. I have not deemed it necessary to illustrate the manner of fastening these sheets together and to their associate parts, as the same is well known and understood to those skilled in the art.

Referring now to Figs. 3, 4, and 5, 17 indicates parallel bars, preferably channels, whose ends are beveled to abut against and be secured to the legs of the cross-ridge 16 by means of rivets and suitable corner connection plates or angles. In addition to strengthening the deepest portion of the cross-ridges these bars 17 provide a support for the dooroperating mechanism. The doors 18 for closing the exits for the load are hinged bysuitable devices to the legs of the cross-ridges 16, the two doors secured to each cross-ridge being companions and forming a pair. These doors are connected together by yokes 19, whose inner extremities are arranged upon a common pintle 20. The ends of this pintle are received in slots in plates 21, which plates are riveted or otherwise secured to backingplates 22, these two plates 21 and 22 being of substantially the same shape and secured to the bars 17 by suitable rivets. The plate 21 is reinforced by a rib 22 on its outer face, (see Fig. 5,) while the lower ends of the pairs of plates 21 are connected by a tie-plate 23. The advantage of this construction resides in its simplicity and the ease with which it may be assembled and placed in position. The ends of the pintle 20 are received in the slots in the plates 21, and by providing suitable washers 24 on each side of the yokes 19' where they are strung on the pintle no fastening devices are necessary,- as the back plates 22 prevent lateral and longitudinal displacement of the pintle. The lower ends of the slots in the plates 21 are preferably left open, so that by disconnecting the link from the pintle and removing the tie-plate 23 the pintle may be dropped through the bottom of the slot for purposes of repairs, &c.

25 indicates a link mounted on the pintle between the washers 24 and pivotally connected at its other end to a rock-arm 26. This rock-arm is formed on the inner end of an operating-shaft 27, mounted in suitable bearings provided on one of the channels 17 and the side sill 4, the outer end of said shaft being formed non-circular for the reception of a suitable wrench, whereby said shaft may be rotated, said outer end also carrying a disk 28, having radial projections for cooperating with pawls 29, whereby the doors 18 may be locked in their open or closed positions. I

The principle of operation of the type of door shown is old and well known, and I do not claim the same here. However, so far as I am aware the construction and arrangement of the pintle-guides are new.

I will state that the edges of the sheets iminediately adjacent the door-opening are prefl erably reinforced by suitable angles for wellunderstood purposes.

I am aware that minor changes in the arrangement, construction, and combination of the several parts of my device can be made and substituted for those herein shown and described without in the least departing from the nature and principle of my invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-
