RAILWAY-CAR- CONSTRUCTION.

Application filed May 2 4, 1923, Serial Ij'o. 641,121. Renewed January 31, 1925.

To all whom it may concern:

Be it knownthat LARGYLE CAMPBELL, a citizen of' the United States, residing at Chicago, in-the countyof Cook and State of Illinois, haveginvente'd a certain new and useful Improvement in Railway-Carv Constructions, iof whichgthe following is a full, clear, concise, 3.-11d-;jXaCl3 description,

reference being had to' 'ithe accompanying drawings, forming a part of this specifica:

tion.

This invention relates to improvements in railway car construction. I One ob ect of my Invention 1s to provmle a car of the dumping type having the maximum over-all Width possible under given roaol clearance andth'e maximum length of the car consistent with the application, to

the outer side of the car, of the usual safety for a car havin a maximum and given helg t.

appliances-required bylaw to the endthat the maximumpossible capacity is obtained.

' Another object-of theinvention is to pro- -vi'de an improved and simple connection {between the bolster and sides of the car.

I illustrating substantially one-half thereof, @said section corresponding substantially to fth'e section lined--23 ofFig. 1." Figure 4' T My invention further resides in certain details ofconstruction as will more clearly appear 1 from the description and claims hereinafter following.

In the drawings forming a part of this specification, Figure 1 is a broken side elevationalview of part of a-hopper car,

Serial No. 585,432, filed April 4th, 1923, and of which thisapplication is' a continuationiin part. The portions E of the side walls of-the carintermediate the body bolsters,,are spaced apart the maximum permissible distance allowed service and, preferably, each. consists of sheet metal plates 1O, preferably inclined upwardly and inwardly near the tops thereof as shown at 11 and thence upwardly as shown at'12 and there secured to the vertical flange 13 of a longitudinally extending top rail member 14:. The latter preferably consists of a bulb angle disposed with the bulb 15 thereof on.

the outstanding edge of the flange 16 which is so disposed as to be in a horizontal plane. Each end portion or sheet D of each side .wall consistsof asheet metal plate-l7 hav 'ing the major or main section 20 thereof,

extending in the same plane as the plane of the intermediate portion E of the side wall The sheet 17, near the extreme end of the car is offset inwardly to provide the offset section 18 for the purposeof accom- .modating the usual laddef'rungs 23 within .the permissible overall width of the car.

The inwardly ofiset section 18 is secured along its top edge to the top rail member 14, the sheet being also indented along its upper edge above the main section 20 to the same plane as the section 18, as clearly shown in'Figs, 1 and 3. The inclined sections between the main outermost section 20 and the inwardly offset upper edge is indicated at- 21, and 22 indicates the ofl'set between the main section 20 and section 18,

the former ofi'set extending horizontally and the latter vertically. 'It will also be noted that the vertical edge of the section 18 is connected to the corner post angle 19.

Connection between the sheet 17 andthe adjacent plate 10 is efl'ected by extending the vertical edge of the latter beyond the bolsterto overlie the plate 17 and to which it is riveted.

Extending transversely of the car beneath each sloping end floor is the body bolster C which, preferably, includes a web plate 2% extending across the plane of the center sill F and bent near the top thereof and secured to the sloping end floor B. The bottom chord of the bolster consists of bottom angles 25 and 26, disposed on opposite sides of the center sills, and bottom cover plate 27 extending from side to side of the car, said bottom plate being secured to side wall bottom angle 28 and to the brace 29 which extends from the bolster to the end sill 30, of the car.

The principal means of connection be- .tween the bolster and the side wall of the car consist of stub stakes G formed of angles 3131 secured to either side of the bolster web plate 2 1 and extended upwardly through the sloping floor of the car for a limited distance and terminating an appreciable distance below the top of the car. Said portion of the stub stakes projecting into the car is contained within the hollow stake H which is preferably formed of sheet metal pressed to a U shape with flanges 3232 to either side of the U whereby connection is made between the stake and the side of the car, the said stake extending from the sloping floor of the car to the top rail bulb member and suitably secured thereto by offset flange as indicated at 40 in Fig. 4;. The lower portion of the stake H is bent at an angle at 33 to form a knee joint and conform to the sloping floor and secured thereto, thus covering the perforation made in the sloping floor for the stub stakes to pass therethrough. Furthermore, the knee joint in the stake forms a secured footing for the stake which insures a very rigid construction for the side and effectively braces the same against inward bending when the car is unloaded by tipping the same on its side in a dumping machine. -Stake H and the stub stakes overlap and extend co-extensively with each other for a limited distance, the rivets 34 passing through both stakes. Consequently, the weakness which would ordinarily be present in a stake made of a plurality of sections is entirely compensated for.

v iT-he sloping floor B is preferably made in sections, consisting of upper section35 and lower section 36 and these sections overlap and are jointed over the bolster as shown in Fig. 4, the slopin floor sections'of the car .being respective y flanged upwardly along their edges at 37 and 38 and riveted to the'side walls of the car. Upper section 35 is formed with an offset at 39 (see Fig. 2) to conform to the offset section of the end portion of the side wall. The knee bracket portion 33 of the stake H also extends over the overlapping portion of the floor plates 35 and 36 thereby obviating the necessity of forming a complicated connection between the side wall of the car and the said overlapping plates where the stub stakes 31 intersect the same.

The brace 29 is extended to the end of the car and is there connected directly to the end sill 30 and to the corner post angle 19, the said brace 29 being oflset as indicated at 37 for the purpose of providing the necessary clearance for the lower rungs of the side ladder.

The corner posts 19 rise vertically from the end sills and are preferably straight, definingthe limits of the side and end walls of the car.

Brackets 38 are disposed at intervals along the side of the car and assist to brace the top rail member and prevent the same from bending to the side. Each bracket 38 is preferably disposed adjacent a side stake and connected thereto.

From the preceding description considered in connection with the drawing, it will be noted that the planes of the portions E of each side Wall are continued beyond the vertical line of the bolster to a point closely adjacent the ladder rungs so that the maximum capacity is made available for the car within the permissible limits of road clearance. Stated in another manner, the only loss in capacity over a car having the side wall continued literally from end corner post to end corner post,

all in the outside plane of the side portions E, is that resulting from the inwardly offsetting of the sections 18 and as to these, it will be notedthat, on account of the sloping end hopper sheets and general conformation of'the car, the indented portions are of the minimum vertical height.

I have shown and described my improved invention in connection with a hopper car but it will'be understood that the same is not limited thereto.
