RAILWAY DUMP-CAR.

Specification of Letters Patent.

Patented J une 4, 1912.

Application led April 19, 1909. Serial No. 490,752.

To all whom t may concern.'

Be it known that I, CLINTON W. RUSSELL, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Railway Dump-Cars, of which the following is a. specification, reference being had therein to the accompanying drawings.

The invention relates to railway dump cars and consists in various features of construction particularly designed to secure greater strength, rigidity and durability, to gether with simplicity and cheapness in construction.

In the drawings; Figure l is a sectional end elevation of the car; Fig. 2 is a sectional side elevation'; and' Fig". 3 is a plan; and Fig. I is a fragmentary section through one end of the door.

A are the axles, B the wheels, and C a frame supported thereon preferably through the medium of bearings D arranged on the inside of the wheels. This frame preferably consists of lcross beams E arranged above each axle and in the vertical plane thereof, the longitudinal side bars F and the centrally-arranged main sills G mounted upon said cross beams. The beams F are supported upon the bearings D through the medium of brackets H, and these are preferably formed with inwardly-projecting lateral extensions I which form a wide bearing for the beams and brace the brackets from angular movement. The car body J is supported upon this frame by a pluralit-y of rocker bearings K spaced along the longitudinal sills G and is normally held from tilting by the braces upon the opposite sides of the center. It is one of the objects of the present invent-ionto obtain a construction of body with which the stresses from the load upon any portion of the floor will be distributed without distortion of the struc ture. To this end, the body frame is formed of a series of longitudinal sills L, L', etc., and truss cross sills M. The longitudinal sills preferably` extend unbrokenly the entire length of the frame and the central sills L are of greater depth than the sills at the sides. As shown, these longitudinal sills are in the form of Z-bars with verticallyextending webs and oppositely-extending flanges. The cross sills are formed by upper plates or cord members M extending across above and secured to the upper flanges of the Z-bars, while below said bars is arranged a bowed cross member M2 preferably formed of a channel bar and secured to the lower flanges of the Z-bars. Diagonal braces M3 are also preferably secured to the lower and upper flanges respectively of adjacent Z-bars.

It will be observed that the frame constructed as described is strongly braced and trussed, and that stresses from an unevenly distributed load are conveyed without ma terial distortion of the frame to the rocker bearings K. The upper members K of these bearings bridge across the central Zbars to which they are secured and filler blocks MJL are preferably placed between the members M and the members K.

With the construction as thus far described, it will be observed that the stresses from the load are iirst carried into the central longitudinal sills Gr of the frame C and from the latter into the cross beams E, which are directly above the axles and are supported from the bearings D by the brackets H. It is, however, necessary to further support the body upon opposite sides of the rock bearings to prevent tilting, and it is usual to arrange a series of rocker braces along the side members of the truck frame which extend upward and support the body. With such constructions, the load is frequently sufficient to distort theseside members of the frame and even to cause the breaking of the same. I have avoided this difficulty by arranging braces directly above the axles so that stresses from the load are conveyed directly through the brackets H to the bearings D. relieving all stress from the side members F.

In detail, N are members secured to the opposite ends of the bea-ms E and constitute abutments for limiting the tilting movement of the body J. These abutments are pivotally secured to brace arms O which, at their upper ends, preferably carry rolls O and are connected by toggle links P, P to the central sills Gr. The links P are mounted upon rock shafts Q, which extend to the end of the frame C and are there provided with operating levers Q. Thus by rocking the shafts Q the links P, P, may be folded, rocking inward the brace arm O, and permitting the tilting of the body. The roll O preferably engages a bearing O2 arranged in one of the channel members M2, and this bearing is of sui'licient length to contact with the roll during its entire travel.

The car body J may be of any suitable construction, comprising a floor R secured directly to the frame, and end plates S which are secured to uprights S att-ached to the frame. The side doors T of the body are secured to links and operating mechanism forming no part of the present invention, by which they are withdrawn as the body is tilted. The links U are pivotally secured to the ends of the doors T, and there is also a truss rod V extending centrally and longitudinally .of the door. In order to provide rigid abutments for this truss rodI preferably form the door with longitudinally-extending metallic members, preferably angle bars IV, at the upper and lower edges thereof and at the end arrange a pair of vertically-extending angle bars X, X. These bars X, X, are spaced to receive the links U having a filler block Y between them at the point of engagement with the truss rod V. The bars X, X, are secured to the bars W and abut against the ends thereof and thus a perfectly rigid strut member is formed for the truss rod without depending upon the planks which form the body of the door.

YVhat I claim as my invention is:

l. In a dump car, a door comprising a plank body, metallic angle bars forming edge-binding strips, a pair of angle bars at the end of said door having overlapping flanges secured to the side and spaced flanges parallel to the end of the door, the inner of said spaced flanges bearing against the ends of said edge-binding strip, and a link for swinging the door pivoted between said spaced flanges.

Q. In a dump car, a door comprising a plank body, metallic angle bars forming edge-binding strips extending longitudinally of said body, a pair of angle bars at the end of said body, having overlapping fianges secured to the sides and spaced flanges parallel with the end of said body, a filler block between said spaced flanges in the central portion thereof, a truss rod passing through an aperture in said flanges and filler block, and anchored thereto, and a swinging link pivoted between said spaced flanges.

3. Ina dump car, the combination with the axles, of journal bearings thereon, a cross beam supported upon said bearings in the vertical plane of the axles, a longitudinal sill supported centrally upon said cross beam, a platform and a side support for the platform in the Vertical plane of said axles.

4. In a dump car, the combination with an axle, and a rigid platform; of a oentral rocker support for said platform, a cross beam in the vertical plane of the axle bearing said central rocker support `and a side support for said tilting platform in the plane ofsaid axle and mounted upon said cross beam.

5. In a dump car, the combination with an axle, of a cross beam arranged in the vertical plane of said axle, journal bearings on said axle and brackets upon said journal bearings having inward lateral extensions forming a wide supporting bearing for said cross beam.

G. In a dump car, the combination with the wheeled axle, of journal bearings upon said axle inside the wheels, a cross beam m l the vertical plane of said axle, anda bracket l having an inward lateral extension forming a wide supporting bearing for said cross beam and resting upon said journal.

8. In a dump car, the'combination with an axle, of a cross beam in the plane of said axle and mounted thereon, a central longitudinal sill supported upon said cross beam, a tilting platform having a rocker support on said central sill, a rocker brace forming a side support for said platform pivotally mounted upon said cross beam, and toggle links for rocking said brace.

9. The combination with an axle, of a tilting platform, a central rocker support for said platform, a cross beam in the vertical plane of the axle and supported thereon forming the support for said rocker bearing, a rocker brace secured to said cross bar in the plane thereof and forming a side support for said tilting platform, and a bumper at the end of said cross beam forming a support for said platform in tilted position.
