a corporation of Ohio Filed July 14, 1958, Ser. No. 748,343 8 Claims. (Cl. 105409) This invention relates to side wall structures for insulated railway cars.

It is an object of this invention to provide metallic side wall structures for insulated railway cars which shall permit more eflective use of the insulation employed in the side wall structures.

A further object is to provide metallic side wall structures for insulated railway cars which shall minimize the amount of voids in the side Walls.

A further object is to provide side wall structures for insulated railway cars which shall embody metallic intermediate posts and sheathing wherein the posts are so related to the sheathing as to permit a more complete development of the insulating value of the insulation used in the side wall structures.

A further object is to provide welded metallic side wall structures for insulated railway cars which shall embody intermediate posts and sheathing wherein the sheathing adjacent to the posts shall be so formed as to reinforce the sheathing, prevent buckling normally resulting from welding and break up the monotony of appearance of the side wall structures.

A further object is to provide welded metallic side wall structures for insulated railway cars which shall embody intermediate posts and sheathing wherein the posts shall be so conformed as to lie partly inwardly and partly outwardly of the plane of the sheathing.

A further object is to provide welded metallic side wall structures for insulated railway cars which shall embody intermediate posts and sheathing wherein the posts and sheathing shall be of such configuration that a portion of the posts shall project outwardly beyond the plane of the sheathing and be received Within the conformations formed in the sheathing.

A further object is to provide novel intermediate posts for the side wall structures of insulated railway cars.

A further object is to provide novel intermediate posts for the side wall structures of insulated railway cars which shall be at least as strong as the intermediate posts in general use and permit a decrease in the projection of the posts into the cars.

Other objects of the invention will become clear as the description thereof proceeds.

In the drawings forming part of this specification:

FIG. 1 is an elevation of a portion of a side wall structure for insulated railway cars embodying the instant invention.

FIG. 2 is a horizontal section taken on FIG. 1.

FIG. 3 is a horizontal section taken on line 3-3 of FIG. 1.

FIG. 4 is a vertical section taken on line 4-4 of FIG. 1.

FIG. 5 is an elevation of a portion of a side wall structure for insulated railway cars embodying a modification of the invention.

FIG. 6 is a horizontal section taken on line 6-6 of FIG. 5.

FIG. 7 is a horizontal section taken on line 77 of FIG. 5.

KG. 8 is a vertical section taken on line 3-8 of FIG. 5.

Referring first to the embodiment of the invention illusline 2-2 of trated in FIGS. 1, 2, 3 and 4, the numeral 10 designates a portion of a side wall structure for insulated railway cars 5 extending substantially from the door opening 11 formed in the structure to the adjacent end of the structure. It will be understood that the remainder of the side wall structure is complementary to the portion illustrated and is of substantially the same construction.

The side wall structure 10 embodies a customary side plate 12 including an outward, downwardly extending flange 13, an angle side sill 14 having an upstanding leg 15 in substantially vertical alignment with the depending flange 13 of the side plate corner and door posts 16 and 17 which may be of any desired construction and intermediate posts id. in the considered embodiment of the invention each of the intermediate posts 18 has a web 19 which as is more clearly shown in FIG. 4 of the drawings extends between and is secured as by means of welding to the opposed edges of the depending flange 13 of the side plate and the upstanding leg 15 of the side sill. The sides of the web 1d are inclined outwardly in opposite directions to provide flanges 29 and 21. These flanges are turned inwardly to provide flanges 22 and 23 which are spaced from the sides of the web 19. The flanges 22. and 23 extending inwardly beyond the web as shown more clearly in FIG. 2 of the drawings. These flanges in turn are bent outwardly in opposite directions to provide inclined flanges 24 and 25 which lie inwardly of the plane of the web 19.

The described structure of the intermediate post 18 thus provides formations 26 and 27 which embody the inclined flanges 2i? and 21 and portions of the inwardly turned flanges 22 and 23 that lie outwardly of the plane of the web. As shown more clearly in FIG. 4 of the drawings these formations merge as indicated at 28 and 29 into the plane of the web 19.

Metallic sheathing 30 is secured to the outside of the intermediate, door and corner posts and to the outside of the flange 13 of the side plate and leg 15 of the side sill. The metallic sheathing extends substantially to the middle of the Webs 19 of the intermediate posts to which the sheathing is welded by a single line of weld as indicated at 31. Where the sheathing crosses the conformations 2d and 27 it is oflset outwardly as indicated at 32 and 33 to provide portions within which the conformations 26 and 27 are received.

The upper and lower edges of the metallic sheathing are adgned so that it may be welded to the side plate and side sill by automatic welding devices. In this welding operation the outwardly offset portions 32 and 33 of the sheathing will prevent buckling thereof. In addition these outwardly oflsct portions serve to reinforce the sheathing and to break up the customary monotony of side wall structures of insulated railway cars. The outwardly oliset portions 32 and 33 of the metallic sheathing merge into the plane of the sheathing as shown at 34 and 35 so that the automatic continuous lines of welding 36 and 37 may be utilized.

it follows from the relationship between the intermediate posts and side plate and side sill as shown in FIG. 4 of the drawing that the web 19 and conformations 26 and 27 of the posts terminate at the flange 13 and leg 15. The remainder of the inwardly extending flanges 22 and 23 and the inclined flanges 24 and 25, however, are continued upwardly as shown at 3% and downwardly as shown at 39 upon the inside of the flange 13 and leg 15 and are welded thereto.

Side wall structures for these cars are insulated. To

insulate the hereinabove described side Wall structure, it is preferred to place a wooden timber 40 against the in-' amazes intermediate posts. To secure the insulating material to the timbers '40 vertically spaced blocks 42 are secured against the inner face of the insulating material by means of Nelsonstuds S welded to the webs 19. These studs extend through openings provided in the timbers 4t? and through the blocks 42 and by means of nuts threaded upon the inner ends of the Nelson studs. These blocks are forced against the insulating material so as to compress ing material is preserved between the vertically spaced blocks 42 as shown more clearly at 44 in FIG. 3 of the drawings. This is made possible by the design of the in termediate posts 19 whereby a portion of the posts extends outwardly beyond the plane of the metallic she-athing while a portion thereof extends inwardly of this plane. Accordingly while the indicated highly desirable result of more effective insulation is secured, its accomplishment is obtained without sacrificing any of the strength of the posts. 7

Moreover, by inclining the flanges 24 and 25 as shown in FIG. 2 of the drawings the size of the voids created by these flanges is reduced thereby maintaining the full thickness of the insulation to the greatest possible degree. He cumulative "eifect of the construction hereinabove described is to reduce materially the hot spots which are normally found in the usual side wall constructions of insulated railway cars and which adversely affect the insulating value 'of the side walls.

A second layer of insulation 45 is customarily used in the side walls of insulated railway cars. With reference to FIG. 4 of the drawings, it will be seen that this layer of insulation is formed of sections which are retained between longitudinally extending timbers 46 and 47 secured in place by being bolted to the spaced blocks .2 as by means of bolts 48 and 49. This insulationis retained in place by means of aplywood inner lining 50 nailed to the timbers 46 and 47. The plywood serves to support an inner plywood cold wall 51 which is customarily nailed thereto through spacer blocks (not shown).

A modified form of intermediate post is illustrated in FIGS. 5 to 8, inclusive, of the drawings. With the exception of the difierence in the intermediate post the side wall illustrated in these figures is the same as that shown in the embodiment of the invention illustrated in FIGS. 1 to 4, inclusive; The considered intermediate post which is indicated by the reference numeral 52 is formed with a Web 53 the sides of which are turned inwardly to form flanges 54 and 55 which in turn are bent outwardly to provide flanges 56 and 57 lying substantially parallel to the web. Intermediate the inturned flanges 54 and 55 the web 53 is pressed outwardly to provide a vertically extending channel portion 58.- At its upper and lower ends the channel portion 58 merges into the plane of the web as indicated at 59 and 60 and together with the web 53 extends between the opposite edges of the flange 13' of the side plate and leg of the side sill and is welded to this flange and leg. The flanges 54 and 55 and 56 and 57, however, continued upwardly and downwardly upon the inside of the flange 13 and leg 15 as shown at 61 and 62 and are weld ed to the inner faces of the flange and the upstanding leg.

To complete the metallic side wall structure sheathing '63 is secured as by means of welding upon the outside of the webs '53, flange 13 and leg 15. The sheathing terminates on either side of the channel-shaped portions 58 and as in the case of the first described embodiment of the invention may be welded to the webs by continuous automatic welding. Moreover, a continuous automatic weld may be employed to secure the upper and lower edges of the sheating to the flanges 13 and 15.

With the exception of the somewhat greater amount of voids which are occasioned by the flanges 56 and 57 the side wall structure described immediately above also decreases the hot spots in the insulated side wall structure and substantially enhances the insulating value of the wall. This is made possible by the design of the intermediate post and its disposition relative to the plane of the sheathing. In this accomplishment no loss in the strength of the post occurs. Both of the posts herein described are at least as strong as the intermediate posts heretofore used; In the last considered embodiment of the invention the Nelson studs S are welded to the outwardly extending channel portion 58. 7

As shown in FIGS. 7 and 8 a substantial portion of the insulating material is provided by the invention between the vertically spaced blocks as shown at 64.

it will be apparent that numerous changesand modifications in the details of the invention will be clear to those skilled in the art. It is intended, therefore, that all such modifications and changes be comprehended within this invention which is to be limited only by the scope of the claims appended hereto.
