My invention relates to the construction of railroad and other cars or vehicles for the transportation of freight,passengers,the.; and it consists in the features of construction as shown in the drawings and as hereinafter described.

The invention has in view the cheapening, strengthening, and simplifying in construction of what are known as steel cars by the use of standard rolled sections of structural steel, such as channels, 850, resulting in the advantages incident to the use of such forms in the construction of rolling-stock, which is peculiarly subjected to excessive strain and wear due to its severe continuous use.

Referring to the drawings, 2 2 are the center sills, made of suitable structural shape, midway of the main framework, running longitudinally for the full length of the car, assembled in close relation to each other and with sufficient intervening space to receive the draw-heads 3 with their accompanying draftgear at each end. On each outer side on corresponding levels with the center sills are the side sills 4:, consisting of suitable structural shapes, as channels or I-beams, with which center sills and side sills are incorporated the cross-sills 5, also of structural channels or I- beams. 'At suitable locations for providing truck bearings are also located the usual body-bolsters, which may be of any preferred or suitable form or construction; but inasmuch as thepresent invention relates particu larly to the construction of the car-body these parts have not been illustrated in detail. The end sills 6 are similar to the side sills and are likewise made of similar structural members incorporated with the side sills and with the center sills by suitable angle-brackets riveted to each, so as to properlysecure the parts together in the manner customary in structural work. The floor of thecar is composed of series of longitudinal channel members 7, laid edge to edge for the full length of the car, their flanges abutting against each other and resting upon the cross and end sills, while theupper faces of the Webs of such channels when thus assembled form aeoutinuous flatsurt'ace, smooth, unbroken throughout the full length and width of the floor. At intervals bolts 8 are passed through the flanges of all of the floor members and also through'the side sills 4 and tightened up by nuts, such bolts thereby securely holding all of the cross members together and in aliuement and rigidly securing them to the side sills.

The sides of the car are constructed in a similar manner of the channels 7, the flanges of which are laid together, as shown, the webs forming the inner surface of the sides of the car in a similar manner to the floor, and such side channel members are likewise held together and in aliuement by bolts 8, extending from top to bottom and through one or both flanges of the side sills 4, tightened up and securely and rigidly holding the members together. These bolts are located at suitable distances apart, and, if desired, between the bolts the flanges may be further secured together by rivets 9, and it will be understood that, if desired, the bolts may be used throughout to the exclusion of the rivets, or the bolts may be dispensed with and the flanges of the channels secured together by rivets only. The ends are constructed in the same manner, the channels extending across from side to side, while at the corners the side and end channels are secured together by structural members having diverging flanges, as angle-brackets 10, upon the inside and outside of the car, riveted through the webs of the channels. An especial advantage of such corner-angles is that when arranged as shown in Fig. 3, wherein a supplemental outer angle 11 is employed, the corner is further stiffened, and such angle provides a convenient bearing for the pushbar of a shifting-engine, thus obviating the necessity of such a separate element being mounted upon the end sill of the car. When thus constructed in the form of a gondola or open-top car, the channels provide a finished floor, sides, and ends, the edges of which require no further reinforcing or finishing, while the corners when secured together as I have shown and described present a finished and workmanlike appearance.

When made in the form of a box-car, as shown in Fig. 7, the roof 12 may be of sheeti'ron or other material and supported upon any suitable roof-framing, while the opening for the door is surrounded by supplemental frame members 13, into which the side members 7 are framed and to which they are secured by riveting through the webs and flanges of such side members and door-frame or in any other suitable manner.

When the construction is utilized in the building of passenger-coaches, as illustrated in Fig. 9, the columns between the windows are made of short sections of channels or other suitable structural shapes, secured together and to the main longitudinal upper and lower side members by bolts or rivets in the manner already described, and the columns may be further reinforced by inner vertical an gles or channel members 13, riveted to the column member in the mannerillustrated in Fig. 10. When utilized as a dump-car, the dumping-sections A A, which may be either single or of double width across the car, are arranged with the independent outer side sills 14 and cross-sills 15, all of the parts being bolted and riveted together in the manner already described. In such construction the upper sides of the center sills 2 are preferably reinforced, as by upwardly-extending angle members 16, which constitute a stiflening hog-back.

The construction is well adapted to utilization in dumping-cars. The floor provides a perfectly smooth hard surface, upon which material of all kinds will readily'sli'de, while upon a flat surface material maybe shoveled with equal ease, an d'this feature of ease of handling and shifting the contents of the car is an important and valuable one.

The present invention is not designed to relate specifically to any particular type of car or to the details of its construction, but embodies generally the principle of utilizing channel forms of structural steel, whereby to secure the smooth-finished innersurface of the floor, sides, and ends and the various other features of advantage which have been hereinbefore set forth and which will be readily appreciated by all those familiar with the general subject of steel cars. It will be seen also that these inner surfaces in addition to being continuous and unbroken are entirely unobstructed incidentally by rivet or bolt heads, all such parts being entirely covered and concealed from view. None of these securing elements are therefore exposed to the injurious effects of moisture, acid, &c., and they are, moreover, readily accessible and easily removed when for any reason it is desired to do so, as for the replacement of bent or broken parts. When, however, it is desired to cover either the inner or outer surfaces, or both, with wood or other facing materialas, for instance, in the construction of passenger-cars-a suitable wooden framing structure may be easily and readily attached to the metal framework and the superstructure laid over it in any manner desired or preferred.

Various changes, modifications, or adaptations of the invention may be made by the skilled mechanic without departing from my invention, and I do not desire to be confined to the detailed construction as shown and described, but to include all such changes and variations as within the scope of the following claims.
