Application lllcrl March ld, ltflllll.

, ltet'erence is had to the accompanying drawings, which illustrate the preferred 'lt'orm ot the invention. though it is to be un derstood that the invention is not limited to a the enact details ot construction shown and described, as it is obvious that various moditications thereot within the scope oit the claims will occur to persons shilled in the art.

lllolled metallic El hars are desirable as to compression memhers ot the side trusses ot steel trame railway hon cars because ot their great strength in any lateral direction and are also desirable as top chords ot girders l5 hecause ot their great strength (horizon tally) to stitlen the girder against huclrling.

Such d hars are positioned with the web horizontal and the oppositely projecting danges positioned vertically.

llt is customary torivet additional meme hers to the side plate-which members are also riveted to the root sheets. Such an p arrangement unnecessarily increases the weight ot the car as well as` the cost and also 25 increases the time necessary to assernlole the car and to repair it. Punching and riveting are expensive in time and money.l

llt is customary to attach the roohng sheets to the upstanding vertical dange oit the Z har side plate so that the horizontal web ot the side plate actually is a part ot' the root ot the car, hecause itis a covering tor that part ot the interior et the car between the outside sheathing and the lining, therefore, l" such portion should he inclined or sloped to ltorm a watershed and also to prevent the accuinulation ot cinders, dirt, etc., which would hold moisture and cause oxidation.

llhe line ot impact ot cars in coupling and switching is through the couplers, considerahly helow the center of gravity of the car, theretore, the inertia ot the car body tends to move it longitudinally .when the car is suddenly stopped or its speed quickly decreased. 'lhis movement is real and causes considerahle damage hy loosening the superstructure and the roof, etc. The inertia force ot any weight in the car is in proportion to its vertical distance above the line of imlll ,tlange to a carline and root sheets oit a rigid type out root..

pact (the coupler), therefore, any elimina- 501 tion ot weight in the root or side plate materially reduces the weaving stresses.

'lhe sidewise swaying or swinging ot the car when moving over an uneven track, crossu ings, switches, etc., increases or decreases 55 the angular relation oit the root to the side plate and has a tendency to distort or hrealr the connection along this line.

rllhe invention relates to a peculiar side plate tor a railway house car having means ou ot attaching a car root thereto and has tor its ohjects the reduction in weight ot the car; the reduction in the original as well as maintenance cost; a stronger and more rigid connection to resist the lateral weaving ot 65 the car; to increase the hearing area ot the root' sheets upon the side plate; to increase the tunnel clearance hy decreasing the width ot" the car at the-eaves and to put the root sheet rivets in direct shear, and, turthermore, to malre a watershed ot that part ot the side plate torming part ot the root olf the car. lln the drawings:

lTig. l shows my improved side plate wherein the upper llange and sloping weh are parallel and wherein the lower tlange and vertical weh are parallel lll ig. 2 shows a construction wherein the slope ot the lower web has heen altered. so that it is not parallel to the upper llange and the plane ot the vertical wel) has heen altered to make the heam symmetrical.

Fig. 3 shows the relation ot the upper 'lll llt

Fig. 4c shows the relation of the upper flange to a carline and root sheets ot a deallole type of root.

Fig. 5 shows a detail view of the rolled section. I

My particular form ot' side plate com prises two obtuse angled welos l-2, one ot which (1) is sloped to 'torna a watershed and the other ot which (2) is positioned suhstantially vertically. The' sloping weh is provided with an integral downwardly projecting Harige 3 for attachment ozt the side wall 4 of. the car andthe substantially vertical flange is provided with an integral flange for attachment of the roof framing elements and also the roof sheets, if: desirable.

Figs. 1 and 2 show my side plate having i the integral flange. (7 8) at the upper part of the vertical web 2 projecting inwardly toward thej'car. llVhen` this flange projects inwardly the distance over the roof sheets is less, thereby not only saving in cost and weight of the car, but also in increasing the tunnel clearances, and minimizing the possible damage by side swiping.

I./"plane's The relative position aiid lengths of the webs and flangesmay be arranged to produce a symmetrical section, which is advan tageous for1 simplicity of design and to avoid confusionin handling the member through the shop'and applying it to the car. In Fig. 1 the webs 1 and 2 are of equal lengt-h and the flanges 3 and 7 are of equal length and "the angular relation of each flange to its adjacent web is the same. The angular relation between web 1 and web 2 may vary and still produce a symmetricalsection. In Fig. 1 the vertical web 2 and the vertical flange Sare parallel, therefore, the "upper flange 7 and the sloping web 1 must be parallel inorder to produce a symmetrical section. The side plate shown in Fig. 1 is symmetrical about line A-A. Y c,

It may' bev desirable to increase the incli-- nation of the sloping web I1 (in order to produce 'a greater watershed, or for some other reason). Such a construction is shown in Fig. 2. In orderto maintain a symmetrical sectiony the position of the substantially vertical web J2 has been altered until the angular relation of the flanges and their adjacent webs is the same. The side plate in Fig. 2is symmetrical about line B-B.

4My construction may be used .with rigid steel roofs or flexible steel roofs. In a rigid steel roof the roof sheets and carlines (if any are rrigidly secured directly or indirect y to the side plate. Such a construction is shown in Figs. 1 and 3. Fig. 3 is a section on line 7-7 in Fig. 1 and shows the relation between the carline 10, the roofV sheets 11 and the side late.

In a flexible roof the carlines 20 are rigidly secured `to the side plate and the roof sheets are usually supported loosely by the side plates (and perhaps other frame members) and-some sort of freely flexible waterproof arrangement is used between the edges of the roof sheets 21 and the carline. A typical construction is shown in Fig. 4, which is a section along line 8-8 of Fig. 2.

g It isunderstood that a flexible or a rigid roof may be used with any construction within this disclosure and still come within the. scope of the invent-ion.
