To all whom it may concern:

Be it known that l, Anornn CAMPBELL, a citizen of the United States, residing at Chicago, in the county of Cook and State of lllinois, have invented certain new and useful lhnprovements in Car Constructions, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to car construction.

One object of the invention is to provide a dump .car of economical construction having maximum capacity consistent with strength and rigidity.

Another object of the invention is to provide a car having a superstructure of maximum width, wherein portions of the sides are inwardly odset for the accommodation of the side ladders within the permissible overall width of the car.

A. still further )bject of the invention 'is to provide a load-carrying car having a superstructure with an open top so arranged as to obtain additional capacity when the lading is heaped, wherein the side top rail is reinforced to provide additional strength and rigidity.

lit is also an object of the invention to vide improved means for connecting the ster to the side of the car.

Uther objects of the invention will-more clearly appear from the description and claims hereinafter following.

in the drawings forming a part of this specificatiom'Figg'l is a vertical, longitudinal, sectional view of slightly more than one hall of a hopper car embodying my improvements,

improvements in roolthe section being taken partly on the longitudinal center of car and partly to one side thereof.

Fig. 14;: is an end elevational view partly broken away, looking from the right in Fig. 12 showing the left corner portion of the end of the car. Fig. 15 is an enlarged horizontal,

sectional view taken sectional view corresponding substantially to A denotes, broadly the end walls of the car; 1

B the sloping end bottom walls; C the body bolster; D the side walls extending between the body bolster and the end of the car; E the side walls intermediate the bolsters; F

the longitudinal center sills; and G the 2- shaped side stake at the bolster.

The sloping end bottom walls B terminate adjacent dumping openings, disposed on each side of the center sill F, and adapted to be sealed by dumping doors l0, hinged to the transversely extending ridge sheets ll. Suitable operating mechanism is provided for the doors, which may consist of a link 12 and crank arm 13 actuated by a transversely extending shaft 14.

My resent invention consists more par ticular y in the superstructure of the car. The -side walls E of the car, intermediate the body bolsters, are spaced apart the maxi- ;fmum permissible distance allowed in service. and are preferably formed of aplurality of sheet -metal plates 15, the joints of said lats15 being covered by narrow plateslfi, the side walls inter- Imediate the bolsters of the car presents a substantially flat and unbroken. surface. Stakes;-; 1-'i' jpreferably"pressed 'out of sheet metal togpresenta substantially U-shaped sectionyare dispqsed inside the car and are offset construction of the side. e5

preferably disposed at the joint between the various sections of plates forming thesides. Along their top edges, the side wallplates are bent inwardly and lupwardly, as shown at 18. Secured to the side plates 15 along their inwardly bent upper edges are bulb angles 19, each having a flange to the upperside of which the inturned edge 18 of the corresponding side wall is riveted and a flange 21 sloping upwardly and outwardly. (3m the exterior of the car wall, and prefer ably adjacent to the inside stakes, reinforcing brackets 22 are provided. The brackets 22 are provided with flanges 23 by which they are secured to the car wall. Each of the brackets 22 are formed with a vertically extending corrugation 24: and is further provided with a flange 25 secured to the upper flange 21 of the bulb angle 19. At suitable intervals angles 26-26 are placed back to back and secured to the interior of the side wall of the car and transversely extending tie members 272l' extend between and are secured to the angle members at opposite sides of the car. The lower margin of each side wall is reinforced by a longitudinally extending angle member 28, extending from bolster to bolster.

The car is formed of restricted width at each end thereof, from the bolster outwardly to the end of the car, primarily, in order to provide the necessary space for the safety appliances and the end portions D of the side walls are each, preferably, formed of a single plate 29 bent outwardly and up wardly at the upper edge thereof, as

indicated at 30, and then upwardly and inwardly as indicated at 31, and suitably secured to the downwardly extending flange 20 of the bulb angle 19, it being understood that the said bulb angle 19 extends throughout the length of the car. The space, between the sections D and E of each side wall of the car is bridged transversely bv the vertically extending stake G, preferably, of

shape section, with the web 32 thereof disposed in a transverse plane and the flanges 33 and 34 secured respectively to the side wall sections E and D, and preferably disposed on the outer face of the car side wall. The upper end of thestake G is constructed to conform to the shape of the plates form ing the respective side wall sections D and E, the flange 33 being continued upwardly.

and turned inwardly as-indicated at 35 and flange 34 being continued upwardly and bent outwardly as indicated at 36 and thereafter merging with portion 35. On the interior of the car, the respective portions of the side wall are connected by a ilate 37, which is secured to the top rail bu b angle 19 and pressed to shape to conform to the On the exterior of the stake G, at the upper-part thereof, a reinforcing bracket 38 is secured to the side of the car and formed with an upwardly and outwardly extending flange 39 secured to the underside of the upper flange 21 of the bulb angle 19. At one side of the bracket a stifl'ening flange 10 is formed integrally therewith providing a construction of greatrigidity and serving to brace the upper flange 21 of the bulb angle 19 against downward bending.

The stake G is reinforced by a vertirally extending angle shaped member -11 disposed on the inside of the car and having one flange 42 secured to the inside face of the plate 15, forming a portion of the wall E, and having the flange as opposite thereto secured to the web 32 of the stake member. The angle member 41 is offset suliiciently to pass over andoverlap the bolster web plate 44, which extends transversely from side to side of the car and between the web 82 of the stake and the said flange 43 of the angle l1, the angle member, web plate and stake being rigidly united by rivets Extending outwardly from the ends of the bolster C to the end of the car are the horizontally extending brace members 45. The braces are preferably formed of channel shape and the web 46 of each riveted directly to the flange 3st of the stake G, and in order to provide additional strength, the upper flange 47 of the brace is turned upwardly in alineinent with the web 16 as shown at 18 and also riveted to the flange 34. The brace is also formed with a flange 49, at the end thereof which is riveted to the bolster web plate 14. The bolster bottom chord consists of bottom angles 50 and 51 and bottom cover plates 52. Bottom cover plate 52 is extended to corn nect with the horizontal flange of the side wall bottom angle 28 and also with the lower flange 53 of the brace 45. Angle50 is extended outwardly and has the horizontal flange thereof riveted to the horizontal flange of the side wall bottom angle 28. The vertical flange of the said bolster bot: tom angle 50 is offset over the flange 13 of the vertical angle 41 and riveted thereto, and to the bolster web plate 44.- and also to the web 32 of the stake G. .The horizontal flange of bolster bottom angle 51 is offset sufficiently to permit the same to overlap the horizontal flange 53 of the braced?) and is riveted thereto and to the bolster bottom plate 52. The vertical flange of the said angle, 51 is also offset to permit the same to overlap the vertical end flange 49- of the brace 45, the securing rivet 54 passing through the said angle 51, the flange -19 of the brace 45, the bolster web plate ii and the vertical flange of the opposite bolster bottom angle 50. In this manner .a most effective connection between the bolster and the side of the car is secured. The bolster web plate 4-]: is preferably formed to extend 1 car by the restricted ing downwardly across the car in one piece, thereby providing a direct connection between t e opposite sides of the car, but it will be understood that it may be formed in sections. The said plate 44 is bent upwardly at and secured to the underside of the sloping end floor B.

The brace 45 is extended to the end of the car and is there connected directly to the end sill 56; each of the corner posts 57, preferably, consists of an angle which extends upwardly from the end sill to within a short distance of the top of the car, terminating at the bend 30 in the side plate 2.9 The vertical end wall A is formed of a plate 58 reinforced at the top by a bulb angle 59, and a horizontal connection 60 unites the same with the side top member 19. A vertically disposed connection 61 connects the vertical. side and end walls at the upper part of, each corner of the car. Said connection has a wall 62 of irregular shape conforming to the shape of the side wall formed by bends 3O lying the end plate 58, the said walls of the connection are each extended downwardly andoverlie the corner angle 57 and are secured thereto by a plurality of rivets6 1.

Tn the recess provided at each end of the width thereof, the side ladders formed by the sill steps 66, are, disposed. Ladder treads 6'? are also provided on the end of the car in the usual manner.

The sloping end floor B of the car ,is

preferably formed in a plurality of sections,-

being divided at the bolster. ,The lower portion thereof consisting of a plate 68, which is flanged upwardly at 69 and secured to the side of the car, said flange being made to conform to the offset construction of the car as indicated at 70. The upper portion of the sloping floor B consists of a plate 71 flanged at 72 and 73 and riveted to the end plate 58 and side plate 29, respectively. \Said flange 73 isotl'set andoverlaps the offset portion oftjthe lower portion of the sloping floor.

Tt will be evident that the vertical stakes G arranged as hereinbefore described provide vertical stiffening members, at the bolsters of great strength, resisting outward bulging of the car sides, which do not in: pede the flow of the discharge material from the upper portion of the sloping fioor towards the discharge opening.

In Figs. 12' to 15 inclusive, a modified form of side wall construction is shown, wherein the recess for. the accommodation of the slide ladder treads is constructed independently of the bolster.

In said construction denotes the side top bulb rail having flange lll'sloping upwardly and outwardly and a flange 112 slopand outwardly therefrom. The side wall intermediate the body boland 31, and also a wall 63 over.

body bolster is a ladder treads 65'and sters consists of a plate 113, bent inwardly and upwardly at 114 and secured to flange 112 of the top rail. The lower margin of the plate 113 is reinforced by angle 115. The side plate 116 extending from the bolster to the end of the car is bent upwardly and inwardly at 117, preferably in the same plane as plate 113, and secured to the top rail. Near the end the side 116 is offset as indicated at 116 thereby presenting a panel, spaced from the main body of the plate and within the recess formed thereby are disposed the side ladder treads 118. The panel 116 is preferably produced by deflecting the main body of the plate inwardly, by forming a longitudinal inwardly and downwardly extending bend 119 and a vertically extending bend 120. At the bolster the respective side plates ,are united by a splice plate 121 disposed on the outside face of the car side wall, and a stake 122 on the inner side thereof. The stake 122 is preferably in the form of a pressed plate extending through the end sloping floor 123, and is connected to the bolster web plate 124 by means of plates 125 which are disposed on either side thereof.

Extending from the end sill 126 to the brace 127 which is bent as indicated at 128 to provide the necessary clearance for the side ladder. Said brace 127 is connected to the side directly by means of a gusset 129. The bolster bottom plate 130 is extended outwardly and secured to the lower flange 131 of the brace 12? and also to the bottom angle 115 of" the side wall.

The end wall of the car consists of a sheet metal plate 132 reinforced at the top by bulb angle 133. Connection between the end wall and side wall is made by means of corner post angle 13 1, vertical top corner connection 135 and horizontally extending top connection 136. The usual ladder treads 137 are provided on the end of the car as shown.

A reinforcing bracket 138 having a stiffening corruga ion 139 pressed therein is secured to the top bulb rail and serves to restrain the top of the car against outward bulging.

While I have shown and described my improved construction in connection with a car .of the hopper discharge type, it will be understood that the same is not limited thereto. but may be applied to other types of cars, wherever it is desired to utilize the full permissible clearance in the construction of railway cars for the purpose of securing increased load-carrying capacity.
