SPECIFICATION forming part of Letters Patent No. 777,473, dated December 13, 1904. Application filed February 2, 1903- Strial No. 141,415. (No model.)

To all whom it may concern.-

Be it known that we, FRANK S. INeoLDsnY and JOSEPH R. BOWLING, citizens of the United States, residing at St.Louis, in the State of lVIis souri, have invented a certain new and useful Improvement in Railway-Oars, of which the following is afull, clear, and exactdescription, reference being had to the accompanying drawings.

The invention relates to certain inprovements in railway-cars, particularly such as are constructed of metal.

Many of the improvements are designed more especially with reference to dumping coke-cars of the Ingoldsby type. One of the prominent features of the Ingoldsby type of car is a central longitudinal beam to which are hinged dumping-doors which swing downward at their outer edges. A coke-car cmbodying this type is shown in our prior application, Serial No. 120,923, filed August 25, 1902, and many of the features in the present invention are an improvement thereon. Other features of the invention, however, are applicable to various railway-cars whether of the Ingoldsby type or not and whether they are dump-cars or of other style.

The features which are peculiar to the pres ent invention will be herein clearly described and definitely set out in their essential combination in the claims, to which reference is hereby made for a summary of the invention.

In the drawings, Figure 1 is a side elevation. Fig. 2 is a vertical section, and Fig. 3 is a top plan, each of these figures showing a little over half of the car. Fig. 4 is an end view, and Fig. 5 a transverse section, of the car.

The side of the car is designated A. It is composed of a truss whose lower chord is a plate-girder. Thus the truss, as shown, con: sists of the upper chord a (t the main inclined struts a, and other inclined struts a and vertical struts, as a a, and a lower chord, itself a plate-girder, composed of the plate (4 an upper flange a therefor, and a lower flange a. The plate a of this girder stands outside of and continues downward from the plate a", the two plates making the side wall of the car.

As will be seen by an inspection of Figs. 1 and 2, the angle-flanges a of terminate at the struts a, from which point to the end-inclined struts 0, the girder is provided with an angleliange a on the upper inner side thereof. As the struts a cross the plane of the inclinedend floor at a point slightly above the external angle-flange a", this construction locates the girder-flanges where they will not interfere with the discharge of the cargo from the sides and inclined ends of the car and at the same time permits the employment of an upper flange for the girder at a point between the strut a and the end of the car where it will not interfere with the operation of the dumping mechanism.

By having the lower chord of the truss in the form of aplate-girder we do away with the necessity for counters for unequal loading, for any tendency of the truss to become distorted is resisted by the stiffness of the girder,which would have to bend across its depth to allow such distortion. By doing away with the necessity for counters we are enabled to make a doorway in the car side. This feature is of great importance. It enables us to carry the load by a most effective structure-11a1nely. a truss-and at the same time it enables us to have one or more open rectangular panels in that truss. It is not necessary to make the girder strong enough to carry the entire load, but simply to have suflicient tensile strength to act the tie of the truss and suflicient stiffness against bending to provide for the unequal loading, as above explained.

The upper chord of the truss is composed of a pair of oppositely-facing angle-beams rt a riveted back to back through their vertical sides. This makes a top beam of large horizontal width to resist the outward bowing of the car caused by the load. This wide upper chord is secured at its ends to the upper ends of the main struts a, and it forms a beam between these points. To securely anchor these points, we provide the diagonal braces B, running across the car from near the upper ends of the main struts to the cornor of the car at the opposite side, connecting-plates b and rivets accomplishing the anchorage.

The top beams of the car sides are extended by the beams a running to the end of the car. Across the end of the car at the top is the beam B and across the top, opposite the main struts a, is the beam B. This makes a very rigid anchorage for the long intermediate beams composed of the angles a a securely holding the ends of these long beams. In order to insure against said long beams bending intermediately of their ends, due to outward pressure of the load in one direction caused by centrifugal force when the car goes around a curve, we provide cross-braces 13* across the car, tying the long beams a a on one side to those on the other, wherefore both the sides of the car come into play in assisting to prevent bending of either side.

The result of the above-described construction is that the whole horizontal top of the car becomes, in elfect, a crossbraced truss, with the stress varying according to the centrifugal force, but with the parts so arranged as to distribute and take care of that stress.

At each end of the car are sloping inclinedend floors C, braced transversely by anglestrips 0 0 and supported intermediately by struts 0 Opposite these inclined-end floors the struts a a are on the outside of the car, so that they will not interfere with the discharge of the load on the inclined-end floors. Intermediately of the car the struts a and a are on the inside of the car, so as not to interfere with the girder-flange a.

At the center of the car is a cross-beam D, which is riveted atits ends to the plate-girder and is braced by the strengthening angleirons (Z.

J represents the body-bolsters of the car.

F represents the central longitudinal beam, made in two alined sections, each section passing through one of the inclined-end floors C and secured to the bolster and at their proximate ends each resting on and secured to the cross-beam D.

The cross-plate d within the cross-beam D in alinement with the ridge-plate L serves to transmit the bufiing and tugging strains. The ridge-plate F may be made of as many separate pieces of metal as desired. For example, each sloping side may be a separate piece connected together by the angle-iron f beneath the ridge. The central beam is braced laterally by composite braces E. The construction and support of the central beam is shown, described, and claimed partly in our prior application Serial No. 120,922, filed August 25, 1902, and partly in the application of Frank S. Ingoldsby, filed August 25, 1902, and serially numbered 120,959.

Pivoted to the longitudinal beam are the dumping-doors G, which are shown provided with toggle mechanism P for raising them.

These doors have floor-beams g, which are adapted to be engaged by hooks K, pivoted to the sides of the car and projecting through the lower flange a thereof, these hooks being connected together by alink L, which is adapted to be operated by a lever M. The arrangement of the hooks passing through the flange a and of the plate of the door Gr, abutting the lower side of that flange, is described and claimed in application by us filed February 2, 1903, and serially numbered 144,915.

A feature of importance in the present invention, however, is the means we employ for stiffening the outer edge of the door Gr, so that it shall not be bent by the bumping it receives when it drops and impinges the bumpers e, of which four are shown for each door and which are carried by the cross-braces E. This stiffening means consists of a Z-bar g, riveted to the under side of the door near its free edge. The web of the Z-bar is perforated to allow the passage of the floor-beams g; but this perforation being more or less nearly in the neutral axis of the Z-bar does not weaken it to any great extent. The construction makes a very stiff and effective brace.

J represents the body-bolsters, having an upper tension member j a lower compression member 1', and an additional tension-strap j", which is the full width and length of the bolster and passes between the center frame of the same and the compression member and then diagonally upward over the struts j and then downwardly along the tension-strap f and over the end of the compression member 7', where it is secured, as represented in Fig. 1.

j represents the stirrup.

The main struts a of the car side, the plates a of the side girders, and the channel-beams a, which form extensions of the lower chord of the car sides, rest on and are secured to the stirrup-plates '*0f the bolster. The diagonal I-beams N, passing through the car from its ends to its sides, pass through the bolster and are there suitably secured.

The details of construction of the bolster do not form any part of the invention covered by this application, the same being shown, described, and claimed in application Serial No. 156,358, filed May 9, 1903, a division of this application.

At the end the car is braced by beams Q running from the end sill S of l the car to the top thereof and the diagonal beams Q, running from the corners of the car to an intermediate position at the end of the top. Corner-posts Q are also provided for the car. Connectingplates 9 q and Q2, properly located, and suitable rivets serve to make the connections desired.

The metal plates a, which constitute the side walls of the car, do not run to the extreme height thereof, but terminate something over half-way up with an angle-strip 0/. Above this angle-strip we provide suitable vertical slats a, leading to the top of the car. This makes a very light structure and one very suitable for handling coke.

The doorway through the car side is adapted to have its lower portion closed by the door T, which is hinged at the lower edge of the doorway. This door may thus be turned down into a horizontal position, as shown in full lines in Fig. 5, forming a platform upon which the load may be wheeled by a wheelbarrow in filling ,the car, or it may be turned up vertically to close the doorway, as shown in dotted lines in that figure. On the under side of this door it is provided with steps a to enable the attendant to more easily climb out of the car. For the same purpose handholds a are provided on the inclined end floors of the car in such position, however, that they will not interfere with the discharge of the load. The upper portion of the doorway above the door T and below the plate a of the car side is adapted to be closed by a small sliding door U,which carries at its upper end rollers if, whereby the door may he slid along and suspended from a track a, carried by the outer side of the car side. When in position, the lower edge of this door is swung into the doorway, thus not only closing the doorway, but holding itself from longitudinal shifting. This is shown, described, and claimed in our application Serial No. 120,923 referred to.

V designates gravity-latches pivoted to the opposite sides of the doorway, so as to be swung down and engage the upper edge of the door T and hold the same closed.

The door U carries a pair of sliding bolts a, connected by a link a to an operating-handle a". When this operating-handle is drawn outward, the bolts are drawn toward each other, and when the operating-handle is forced inward the bolts are spread outward. In this outward spreading the bolts pass between the flange a and the edge of the latch V, and thus hold the upper door in place against either inward or outward movement. A sealpin a through the operating-handle u and a stationary clip holds the bolts in place.

The details of the door mechanism do not form any part of the invention covered by this application, the same being shown, described, and claimed in application Serial No. 182,064; filed November 22, 1903, a division of this application.
