IDOUBLE-HOPPER-BOTTOM CAR.

SPECIFICATION forming part of Letters Patent No. 663,030. dated December 4, 1900.

Application filed August 17, 1900.

To {LZ/ whom, it may concern.-

Beit known that I, GEORGE I. KING, a citi- Zen of the United States, residing at the city of Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Im provement in Double-Hopper-Bottom Cars, of which the following is a full, clear, and eX- act 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 side elevational View of one end of my improved car. Fig. 2 is a top plan view ofthe same. Fig. 3 is a vertical sectional View. Fig. 4: isa top plan View of the underframing. Fig. 5 is an end elevational View. Fig. 6 is across-sectional view on line 6 6, Fig. Lt. Fig. 7 is a detail view of one of the girder-plates used in connection with the center sill, and Fig. Sis a detail sectional View on line 8 S, Fig. l.

This invention relates to a new and useful improvement in car construction, being designed particularly for use in connection with dou ble-hopper-bottom carsthat is, cars provided with a centrally-located cross-ridge intersected by the longitudinal ridge and providing, practically, four points of discharge for the load. So far as this is concerned, however, I do not wish to be understood as limiting my invention for use in connection with a double-hopper-bottom car, as the same can with slight changes be employed with what is known as a single-hopper-bottom car that is, one wherein the cross-ridge is absent. Also certain features of the invention, particularly those relating to the underframing, can be employed for use with other types of cars-such as flat, gondola, and boX cars. I will state that as a general proposition, irrespective ofthe particular style of car produced-that is, flat, gondola, box, or hopperbottom cars-the framing em ployed for carrying the load may be of several different types. This framing where it is located under the floor-line may be in the form of wooden sills trussed by suitable rods, or the sills may be of commercially-rolled forms, with or without truss-rods, or of pressed forms, in which latter instance the sills are made deepest at their Serial No. 27,161. (No model.)

middle portion, where they are subjected to the greatest strain, and shallower at their ends. Another type of car is one wherein the side walls are made of metal plates, forming a plate-girder, the side walls being designed to carry all or nearly all of the load. In this latter construction a center sill (or sills) is employed, and very light, if any, side sills are used. Still another type of framing is employed Where room is permitted above the iioor-level-as in gondola, hopper-bottom,and box cars. This type may be designated as the trussed type, wherein center sills are usually provided and side sills are also employed, these side sills forming the lower chords. A rail parallel to the side sills or slightly cambered, if desired, is also used to form the upper chord of the truss. Vertical posts are arranged between these rails, and diagonals are used to complete the structure. In these trussed forms the containing-walls ofthe car may be light wooden planking, as the load is carried entirely by the trussed structure. It is to this latter class or type of car that the present invention relates.

In the drawings, l indicates the center sills, which are preferably made of commerciallyrolled channels with their flanges presented inwardly.

2 indicates the end sill, which may be a casting, and 3 the side sills, said side sills being preferably of rolled-channel form, with their anges presenting inwardly. Suitable connectionplates or connection-angles are employed to attach these sills together, and a body-bolster (indicated at 4E) aftords another and important medium for tying the longitudinal sills, as wellas aording asupport therefor. Corner-posts 5, preferably in the form of angle-bars, extend upwardly to su pport the corners of the car, while intermediate posts 6 rise from the end sill for the same purpose. The end wall 7 of the car is secured to these corner and intermediate posts, said end wall resting upon brackets 8, arranged on said posts, said brackets carrying cleats 9, to which are secured the inclined iioor-boards 10.

l1 indicates a floor-beam, preferably in the form of an angle extending transversely the floor of the car and supported by floor-supports 12, which incline downwardly andout- IOO wardly and are secured by connection-plates 13 to the center sills. The ends of floor-beam 11 project outwardly beyond the side walls of the car andare secured to the web of Vone o'f the Z-bar diagonals hereinafter described.

14 indicates a cover-plate for the bolster, upon which'is arranged a floor-brace 15. (See Fig. 3.)

16 indicates angles secured by suitable connections to the side and center sills, which angles tie said sills and also form floor-supports.

l7indicates the side hopper-plates, secured at their upper edges tothe side sills and provided along their inclined edges with inturned flanges 18, which form floor-supports and to which the floor-boards 10 are secured.

19 indicates straps whose ends are bent up and secured to the outer faces of the inclined hopper-plates, said straps tying said hopperplates in position. Angles 2O and 2l are also riveted to the lower ends of the flanges of the inclined hopper-plates for bracing the structure and forming floor-supports. These an- 'gles are held in position by corner-bands 21".

cured to the outer faces of the webs of the center sills and extending some distance along said center sills, said plates being preferably deepest at their middle portions and inclined at their lower edges, said inclinations coinciding with the inclined lower edgesof the hopper-plates 17. The lower edges of these plates 26 are flanged inwardly, as at 27, (see Figs. 6and 7,) said inwardly-extending flanges forming, substantially, the tension-flanges of the plates. These plates 26, in addition to forming the inner hopper-plates for preventing the load from interfering with the door or the brake-operating mechanism, also form the webs of a plate-girder structure by being attached to the center sills, the upper flange of the center sill forming the compression-flange, while the flange 27 forms the tension-flan ge of the girder. In this way the center of the car is made extremely strong, the girder being made deepest at its middle p0rtlon, the deep web 0f the girder being utilized as the side wall of the hopper-opening. The inclined ends of the plates 26 are likewise flanged, as at 27a, (see Figs. 4 and 7,) said flange 27a being presented outwardly, so as to afford a support for the floor-boards 10.

If desired, hatten-plates 2S orV lattice-bars may be connected t0 the bottoms of the cen- V verse plane of the body-bolster and preferably consisting of two parallel Z-bars, with their outer flanges presented away from each other and their inner flanges presented t-oward each other. (See Fig. 8.) It is obvious that this post can be made of a single pressed or bent piece of metal. In this manner the planks or boards 32, which form the side walls of the car, maybe directly secured to the inner flanges without the use of furring-strips, ready access being obtained t0 the securing devices.

A connection-plate 33 is secured to the side sill, and to this connection-plate the outer [langes of the transom-post 31 are riveted. By reason of said flanges projecting in opposite directions and away from each other easy access may be had to the rivets for the purpose of driving the same. In fact, a rivetingmachine may be employed to makev the connection between the members of this post and the connection-plate 33.

The top chord 30, t0 which I have before referred, is preferably in the form of an angle-bar whose horizontal flange or member extends inwardly, while its vertical flange eX- tends downwardly. Inside of this vertical flange is riveted a connection-plate 34, and to this connection-plate are riveted the outwardly-disposed flanges of the post 3l.

35 indicates a vertical post, preferably in the form of a Z-bar, which is secured to the bottom chord through the medium of a plate 36 and to the top chord 30 through the medium of the connection-plate 37. This post 35 is preferably located in the center of the car.

38indicates an intermediate post connected t0 the bottom chord through they connectionplate 39 and t0 the top chord 30 through the medium 0f the connection-plate 40.

41 indicates a diagonal, preferably in the form of a Z-bar, whose outer flange is riveted to the connection- plates 36 and 40, and 42 indicates a diagonal, preferably in the form 0f a Z-bar, whose outer flange is riveted to the connection- plates 39 and 34. It will be n0- ticed that these diagonals 41 and 42 are inclined in the same direction, and assuming that We consider this side framing composed of the top chord 30, the bottom chord 3, and the Z-bars as a trussed structure, these diagonals 41 and 42 will be' placed in tension IOO IIO

under load, and preferablyso. Otherwise the section ot' the Z-bars, if placed in compression, would have to be considerably increased in order to safely act as columns.

In order to brace the end of the car, I provide a connection-plate 43 at the end of the side sill, to which and to the connection-plate 34 is riveted a diagonal 44, preferably in the form of a Z-bar.

By using Z-bars in the construction of the vertical posts and diagonals, attaching devices, in the form of rivets or bolts between said parts and their respective connectionplates, can be most conveniently manipulated-in fact, in instances where rivets are used by a machin e-riveter. The attaching devices between the inner flanges of said Z-bars and the boards forming the side walls of the car are also of easy access and can be conveniently manipulated. So far as I am aware I am the first to employ Z-bars for use as vertical posts and diagonals in a trussed structure for car-bodies. Furring-strips 45 are preferably placed in the angle 30 for the purpose of nailing or boltin g the top boards thereto, said furring-strips of course being in short lengths and serving as llers.

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

l. The combination with the inclined hopper-plates provided with inturned fianges at their lower edges for supporting the inclined floor of the car, and straps which extend under the inclined ioor, their ends being bent up against the outer faces of said inclined hopper-plates; substantially as described.

2. The combination with the side sills, of inclined hopper-plates secured thereto, the lower inclined edges of said hopper-plates being v[ianged inwardly to support the inclined floor ofthe car, and straps for tying said hopper-plates in position; substantially as described.

3. The combination with a center sill, of a plate 26 provided with a flange 27 on its lower chords, posts and diagonals, said posts and diagonals being in the form of Z-bars; substantially as described.

5. In a framing for car sides, the combination with upper and lower chords, of Z-bars, vertical posts therebetween, Z-bar diagonals, and connection-plates; substantially as described.

6. A side framing for cars consisting of a side sill forming the lower chord of a trussed structure, a rolled member forming the upper chord of the trussed structure, parallel Z-bars forming avertical postin the transverse plane of the bolster, and intermediate posts and diagonals; substantially as described.

7. A trussed side frame for cars comprising a channel side sill forming the lower chord, an angle-rail forming the upper chord, Z-shaped vertical posts and diagonals, connectionplates for securing said posts and diagonals to the upper and lower chords, and a side wall which is secured to said vertical posts and diagonals; substantially as described.

8. A trussed side frame for cars comprising a channel side sill forming the lower chord, an angle-rail forming the upper chord, Z-shaped vertical posts and diagonals, connectionplates for securing said posts and diagonals to the upper and lower chords, a side wall which is secured to said vertical posts and diagonals, and furring-strips between the angle-rail and the side wall substantially as described.

9. In a trussed side framing for cars, the combination with a channel side sill, vertical posts and diagonals secured thereto, and an angle-rail to which the upper ends of said posts and diagonals are secured, said anglerail having its horizontal member extending inwardly and its vertical member extending downwardly, furring-strips inclosed by said members, and a side wall which is secured to said furring-strips and to said vertical posts and diagonals; substantially as described.

In testimony whereof I hereunto affix my signature, in the presence of two witnesses, this 14th day of August, 1900.
