CHARLES DAVIDk BONSALL, O T PARNASSUS, EE-NNSYLVANA, ASSIGNOR TO UNIGN METAL PRQDUCTS COMPANY, OF CHICAGO, ILLINOS, A CORLORATIGN 0F DELA- WARE.

CAR-WALL STRUCTURE.

Application led September My invention has for its object to provide n all metal car construction of novel char- !cter which is unusuallystrong for its weight and durable throughout, which may be conveniently and economically manufactured and transported, is weather proof and which possesses certain other desirable and advantageous features to be hereinafter described and claimed. My sheet metal wall structure is applicable to the end or side of box, automobile, gondola, stock or any other type of railway car equipment.l

The ends of'railway cars are subject to considerable stress due to the shifting of the lading. These blows are imparted to the end over the entire area thereof, or to local areas. Threat is loaded to substantially the top of Vthe car which causes all the blow to be imparted'over the entire area ofthe end. Lumber is loaded to the top ano upon impact the top boards shift causing ablow to be imparted at the top of the end. Sand, chats and other plastic loads and light pipe'cause blows at the middle of the car, whereas-rail,

steel plates, castings and the like cause blows at the bottom ofthe car. l

`While, of course, efforts are made to block the lading in the car, the heavy locomotives, the emergency air brake and the classification hump break the lading 'away from its moorings and throw it against the `end of the car.

A rigid end to a car, and particularly a large box car, materially strengthens the entire superstructure to resist the torsional and weaving movements which not only rack the car to pieces, but causes leaky roofs and inoperative and leaky doors with their consequent damage claims. As it costs as much to transport a ton of freight car as it does a ton Y y of lading it is imperative that the weight of the car must be kept as low as possible, therefore, the end must be very light as well as strong. As freight cars are frequently damaged in wrecks and by other unfair usage, any end will be damaged in service, therefore, it must be capable of being easily` repaired with Vsuch meagre facilities as the railroads are equippedrwith at their outlying repair points.

My wall is `made ofV one or more metallic plates' with their meeting sides overlapped and lured together, the overlappedportions 26, 1925. serial No, 58,845.

being formed to provide members which act as columns to sustain the roof load, as beams to resist the thrust of the lading and as stieners to prevent buckling of the wall. rlhese beam-columns are so formed as to provide ventilators or tlues from the exterior to the interior of the car. Such ventilation is desirable because it prevents the condensation of moisture in the air within the car, which would injure some types of lading.

An object of the inventionis to form the overlapped portions of the metallic plates of a railway ca r wall so as to provide a beamcolumn which also .furnishes means of ventilation for the car.

The Interstate Commerce Commission has prescribed the minimum clearances between freight cars in their order of March 13, 1911, which reads as follows:

No part of car above end-sills withinV thirty (30) inches from side of car, except buffer-block, brake-shaft, brake-wheel, brakestep, running-board or uncoupling lever shall extend to within twelve (12) inches of a vertical plane parallel with end of car and passing through the inside face of knuckle when closed Vwith coupler-horn against the buffer-block or end-sill, and no other part of end' of car or fixtures on same above end-sills, other than exceptions herein noted, shall extend beyond the outer face of buffer-block.

-Any reinforcement in the wall not within thirty (30) inches from the sides of the car may extend to the face of the buffer block. An object of the'invention is to take advantageY of this condition and to make the beamcolumns deeper' near the middle of the car than within thirty (30) inches from the side of the car.

`Theouter corrugated plate prevents rain, falling cinders or the like from entering the iues and the inner corrugated plate prevents sand, grain or similar lading from escaping from the car through the flue.

Another object of theinvention is to arrange the lining boards so as to permit of a deeperbeam-column near the middle of the car than elsewhere.

Another object of the invention is to provide primary reinforcements extending substantially from the underframe to the ridge pole or other roof framing, which members forni excellent anchorage 'and also provide other secondary reinforcements parallel to and spaced apart form the primary reinforcements. These reinforcements vary in depth and width according to conditions.

I have used the terms plates and sheets to simplify the claims, but there is no dit'.- 'erence in their meaning as far as this invention is concerned.

These reiniiorcenients or corrugations may be rectangular, as illustra-ted, or circular, or of any other desired contour.

In .the drawings 1 shows the end of a railway car with my improved Vall applied thereon.

Fig. 2 is a section on line 2-2 ot Fig. 1

Fig. 3 is a section on line 3-3 o'lilig. 1.

Fig. i shows a modified form.

Fig. 5 shows a modiiied form.

Fig. (3 is a perpective view ot one of the plates.

For convenience, I have shown an end wall of `a. box carwherein 1 .is the end sill; 2 the end plate; 3 the corner post; fl the butler block; the end ladder; VG the underirame; 7 the ridge pole and 8 the side plate.

The wall comprises a plurality of inetallic plates 10, 11 and 12, some of which have one or more inwardly projecting corrugations 13 which terminate within the lower edge but extend to the upper edge of the plate and othersV ot' which have one or lre outwardly projecting corrugations 14 ich terminate within lthe upper edge but e v`end to the lower edge of the plate. These lcorruge-.tions are positioned opposite each other and the plates are secured together on both .sidesy oi the corrugations so as to form a box girder.v The corrugation 14 on the outside of the wall is open at the bottom and closed at the top, Vwhile the corrugation 13 on the inside ot' the wall is of reverse formation, te.; closed at the bottom and open at the top, thus .forming a Ventilating communication between the exterior and interior ol the car.-V

The wall may be made ol a pair of corrugated plates 1 5-16 or 17-18 each having a small flange on each side of the corrugavtion, which. flanges are ysecured together to t'orm a beamcolumn and flat plates 19 are insertedL between the flanges and spans the distancev between the respective beam-columns. Such va construction is shown in Fig. 5.

VIt may be desirable'to orm a corrugation near each side of a plate and position such corrugated plates with oppositely projecting lcorrmentions in the overlapped portions of adjacent plates. Such a construction is shown in l? 8.

t may he desirable to form the plate (20) with an inwardly projecting corrugation 13 near one edge andan outwardly projecting corrugation 14C nearthe other edge and position suchplates with opposite'ly projecting corrugations in the overlapped portions of adjacent sheets. Such va construction shown in Fig. 4.

Fig. 6 shows one of the plates 20 of the construction illustrated in Fig. 4l wherein the corrugation 13 near the side 21 ofthe plate terminates within-the lower edge but extends to the upper edge ot' the plate, and the corrugation 14 near the other side 22 of the plate terminates within the upper edge to shear oil this Hare but to utilize it to i obtain greater riveting area, as shown .in Fig. 1.

The filler blocks or nailing of the same depth as the inwardly corrugations so that the lining bear agzjainst and are supported by these corrugrations. The nailing strips are held in place by bolts 26.-

The accompanying drawings illustrate the strips 27 are vproject in g preferred form of the invention, though it to be understood that the inventionv is not limited to the exact details of construction shown and described, as it is obvious that various modifications thereof within the scope of the claims will occur to persons skilled in the art. f
