CAR CONSTRUCTION This invention relates to railway cars, particularly steelcars, which because of their constant exposure to the elements are subject to severe corrosion, especially open top or gondola railway'cars, which are used toy Y haul coal or other similar commodities, and

has for its object the use of relatively non- Y corrosive'materialwherethe maximum corrosionY occurs anda relatively lighter and cheaper material at places less subject to Y corrosion.

ari

Cast metal is not as susceptible to corrosion as rolled steel or rolled iron and annealed ycast metal (malleable iron): is not as susceptible to corrosion as east steel. Mallevable iron is justas strong: under compression as ordinary cast metal and almost as stro'ngas rolled 'steel'under tension. therefore in desio'nin a railway car l prefer to make the load sustaining' members of rolled steel and the members subject more to the actionof corrosion of cast metalyprefer'ably malleable iron, or otherA relatively non-corrosive material.

Steel or iron which has been rolled flat into plates and subsequently bent, stretched or otherwise deformed is moresubj ect to corrofore, l prefer to substitute malleable or 'other cast metal structures in place of-bent steel plates lwhenA such bent plates are abnormally subject yto corrosion; for instance, corner pieces between the vertical walls and the floor of a railway car. In the drawings Figi `1 shows a typical application ofmyV stock, hopper, etc;, as kwell ias gondola cars.

' inventionto a railway car.

Fig. 2 shows a modied form.

The righthand side of Fig. y1 is an elevation of an end of a railway car and the left hand side thereof lis a cross section of the same car.

The car comprises a side wall steel platel 2; a topside chordB; a side sill 4; center sill `10;top cover plate 11; bottomplate 12 and side stake 18.

, In the car illustrated in' Fig. lthe floorl l 20, which is subjected to considerable corrosion, is madeof wood extending substani tiallvfromsidefto side of thefcar, and inorder to protect the side sill 4 ef the car from moisture penetrating through the door causing corrosion of this side sill,I provide a cast metal member having a substantially horizontalv portion 21 overlying the side sill 4 so as `to protect it from the lading. This cast metal member also has an integral substan- A-tially vertical portion 22forming a part' of the side wall of the car. This vert-ical portion extends upwardly any convenient distance and the rolledsteel side wall sheet 2 is se'-V cured to this upper margin and preferably overlaps it on the inside of the car, as shown.

The wooden flooring 20 preferably overlies andrests upon the horizontal portion 21 of thecast metal member and the cast' metal i member preferably covers the entire upper surface of the side sill 4. f

The side stake 13 is secured to the side sill 4, portion 22 and wall sheet 2 so that all these elements reinforce each other to form a rigid structure, therefore, such a cast metallic member performs thedual function of increasing the resistance of the car'wall to corrosion where corrosion is greatest and to strengthen theV car wall where greater strength vis required.

Fig. 2 'shows the vinvention applied to a gondola car wherein the floor comprises a plurality'of hinged doors 30 (hinge not shown). In this figure the malleable iron member V31 has an oblique portion to shed the Y load and lchute it toward the opening.

rlhe invention may be used'in either or both the side and end walls of railway cars.

and any type of railway car, such as box,

rEhe right hand of Fig. 1 showsk the vertical portion 22 Vof the cast metalmember extended aroundA the corner of the car V(14) to form I to be understood that the invention is notV Y limited to the exact detailsof construction shown and' described, as it is obvious that various modifications thereof, within the scope ofthe claims, will occur to persons vskilled in the art.

rlhis is a division of my co-pending application Serial No. 255, 449, filed February 18, 1928.

I claim:

l. In a railway car, the combination of a rolled steel sill, a cast metal member` having a substantially horizontal portion overlying the sill so as to protect it from the lading, and an integral substantially vertical portion forming a part of a wall of the car.

2. In a railway car, the combination of a rolled steel sill, a cast metal member having a substantially horizontal portion overlying the sill so as to protect it from the lading, an integral substantially vertical portion forming a part of a wall of the car, and a wooden Y,

fiooring overlying said horizontal portion of the member.

3. In a yrailway car, the combination of a rolled steel sill, a cast metal member having a substantially horizontal portion overlying the sill so as to protect it from the lading, an integral substantially vertical portion i'orming apart of a wall of the car, `a wooden flooring overlying said horizontal portion of the member, and a rolled steel wall sheet secured to said member.

4C. In a railway car, the combination of a rolled steel sill, a cast metal member having substantially horizontal portion overlying the sill so as to protect it from the lading, an integral substantially vertical portion, a wooden flooring overlying said horizontal portion, a rolled steel wall sheet secured to said member, and a stake secured to the sill, member and wall sheet.

5. In `a railway car, the combination of a rolled steel sill, a door opening, and a east metal member having a substantially horizontal portion overlying the sill so as to protect it from the lading, and an integral substantially vertical portion forming a part of a. wall of th-e car, said member having an oblique portion forming a chute toward said opening.

6. In a railway car, a vertical wall and a floor, said wall comprising` a rolled steel upper portion, a roll-ed structural steel beam, and an intermediate ce st metallic member secured to said upper portion and to said beam, said member having a substantially horizontal flange overlapping the beam and underlying the floor of the car.

7. In a railway car, the combination ot' a structural sill of relatively corrosive material, and a member of relatively non-corrosive material having a substantially horizontal portion overlying the sill so as to protect it from the lading and a substantially vertical portion forming a part of the load retaining means of the car.

8. In a railway car, the combination of a structural sill of relatively corrosive material, a member of relatively non-corrosive material having a substantially horizontal portion overlying the sill so as to protect is from the lading and a substantially vertical portion forming a part of the load retaining means oi the car, and a flooring overlying the horizontal portion of the member.

9. In a railway car, the combination of a structural sill of relatively corrosive material, a member of relatively non-corrosive material having a substantially horizontal portion overlying the sill so as to protect it from the lading and a. substantially vertical portion, a flooring overlying the horizontal portionof the member, and a wall sheet oi relatively corrosive material secured to said member.

l0. In a railway car, the combination of a structural sill of relatively corrosive material, a member of relatively non-corrosive material having a substantially horizontal port-ion overlying the sill so as to protect it from the lading and a substantially vertical portion, a flooring overlying the horizontal portion of the member, a wall sheet of relatively corrosive material secured to said member, and a stake secured to the sill, member and wall sheet.

1l. In a railway car, the combination of a structural sill of relatively corrosive material, a door opening, and a. member of relatively non-corrosive material having a substantially horizontal portion overlying the sill so as to protect it from the lading and a substantially vertical portion forming a part of the load retaining means of the car, said member having an oblique portion forming a chute toward said opening.
