Toll whom it may concern.-

Be it known that I, GEORGE I. KING, acitizen of the United States, residing at Middletown, Dauphin county, Pennsylvania, have in- 5 vented a certain new and useful Improvement in Low-.Side Gondola Cars, of which the following is a full, clear, and exact description. such aswill enable others skilled in the art to which it appertains to make and use the same,

reference being had to the accompanying drawings, forming a part of this specica-A tion, in which- Figure 1 is a top plan view of my improved car, part of the flooring being removed at one I 5 'end to show the floor-f rame underneath. Fig. 2 is a side elevational view, partly in section.'

Fig. 3 isa sectional view on the line 3 3 of Fig. 2. Fig. 4 is a sectional view on the line 4 4 of Fig. 2. Fig. 5 is an elevational view of one end of the car. Fig. 6 is a detail plan view of the connection between the side and end sills. Fig. 7l is a detail perspective view of a modified form of connection between the side and end'sills. Fig. 8 is a plan view show- 2'5 ing a reinforcing cover-plate for'the bolster, and Fig. 9 is a vsectional view'on line 9 9 of Fig. 8.

This invention relates to a new and useful improvement in that type'oears known as 3e gondola,,although it is Obvious that many of the details shown. in the accinpanying drawings and hereinafter described may employed iii -other types of cars.

'The objects of my present invention .are toconstruct a car of rolled or pressed metal and to so arrange and combine the parts as to ob tain the greatest strength with a rcompara- .tively small deadweight ofmaterial used.

Another Objectis to simplify the construc- 4 tion of cars of the type mentioned, rendering, the parts thereof easy of assemblage and reaix-. r With these objectsA in view the invention i F. consists inthe construction, arrangement, and

:"combinatiouj'fbf the several' parts, all as will hereinafter be described and afterward point- In the drawings, 1 indicates the center sill, which is preferably'composed of two channels having their flanges presented outwardly.

2 indicates the body-bolster as an entirety, which consists, preferably, of two I-shaped V webs extending between the center and side' sills, a casting being employed between the center sills, as shown. A bottom cover-plate 55 is riveted to the bottom flanges f the I-shaped 'webs and the center-sill channels. I do not herein claim the construction of this bodybolster. i J

3 indicates end sills, which may be-of any, form, but which are shown as consisting of channels with their anges presented voutwardly.

4 indicates the'side sills, which are preferably in the form of rolled or pressed Z-bars. thebottom angesthereof being presented outwardly, while the top angesare presented inwardly. Theseside sills are connected to the ends of the bolster-webs Vor holsters, las the case may be, and to the ends vof the end sills by suitable connection-plates. As shown in Fig. 6, connection-plates 5 are arranged on, each side of the vertical web Yof the Z-bar,

while in Fig. 7 a single connection-plate 6 is arranged outside the verticalweb of the Z-bar,

the bottom ilange of. the Z-bar being'fcut away to permit the .connection-plate or angle to extendto the,lower edge of the end sill, which end sill, as shown, 'extends below'the bottom flange ofthe side-sill. f

l 7 indicates a Hoor-sheet arranged at the end of the' car,`said door-'sheet being riveted to --thegtop anges of the end, center, and lside sills and extending inwardly beyond the bodynectionplates to. the center and sidel sills.

There are preferably a number of these iloorbeams intermediate lthe holsters..

9 indicates side Hoor-sheets riveted to the top flanges of the center and side sills, abuttjoint being formed between the ends of these side plates and the inner edges of the end plates.

10l indicates the center floor-sheet, which is preferably arranged above the side and end sheets and riveted thereto andto the top flanges of the center sills. This floor-sheet 10 also serves as a top cover-plate for the center sill. A bottom cover-plate 11 may be riveted to the bottom flanges of the center sill, if required,

or lattice-bars may be provided, as is well uning cover-plates 15, which are arranged above the holsters. 4

The side walls of the car are in the forni of sheets 13, riveted to the vertical webs of the side sills, the upper edges of said side sheets havingangles 14 secured thereto. These side sheets serve to carry a portion of the load and in this capacit-y act as plate-girders, the top angles being placed in compression and serving as compression-flanges for the plate-girder side Walls, while the side sills serve as tensionflanges therefor.

From the above. it will be obvious that the Z-barside sills, with their top and bottom flanges presented as shown, perform the functions of providing angular flanges for the attachment and support of the floor-sheets and angular flanges at thebottom loft' the plategirder side walls which serve as tension-flanges for the plate-girder side walls; also, that by the useof commerciallyfrolled Z-bars these two angular flanges are integrally connected, the vertical webs of the Z-bars affording ample attachment' to the lower edges of the side walls which are riveted thereto. These Z-bars also resist buiing and pulling strains in their additional capacity as side sills, they being considerably strengthened in the performance of this last-mentioned function by the side walls l attached thereto, which side walls assist in resisting bufng and pulling strains. Thus in the performanceof the functions attributed to the several members of the Z-.bars other com mercially-rolled shapes might be employed-- such, for instance, las the well-known L-shaped angles, two of which could be used and serve in every particular as Well as the single Z-bar. In fact, by the use of the two L-angles they would be the exact mechanical equivalent of thessingle Z-bar, or, in other words, the single Z-ban would produce the two L-shaped :angles referred to if its vertical web were cut on a line parallel to the flanges. By the use of two separate angles with their horizontal legs or flanges, instead Vof' a single bar with its integrally-connected horizontal legs or flanges, such as the Z-bar shown, the two separate angles would rely upon the plate-girder side wall of the car as a connecting-web, and this side wall could be made as deep as desired or separate angles bespaced as far apart as necessary to give the required section of metal in the connecting-web. These slight variations are all included within the scope of my invention and are not illustrated in the drawings, because they are common expedients and are well known in the art .of car-building.

In the following claims 'by the use of the terrn angular flange I intend to include all forms of` flanges, whether integrally connected or separately attached to the side wall of the car or to the floor-sheet. One advantage resulting from the use of the three angular flanges shown, whether integral or separately connected to the side or floor sheets, isthat the floor is supported bythe intermediate flange, so that the side walls-extend therebeneath and dispense with the use of heavy side sills, the side walls acting as plate-girders and assisting to resist the bufng and pulling strains. Furthermore, by the use of the cover-plates 15, secured to the I-shaped bolster-fillers (which fillers are sometimes called flying transoms) on each side of the centerv sill, I obtain an extremely strong connection at this point, and by extending the end floor-sheet inwardly beyond the bolster the said sheet also adds to the section'of the top cover-plate.

r I am aware that minor changes in the construction, arrangement, and combination of the several partsof my device can be made and substituted for those herein showniand described without in the least departing from the nature and principle of my invention.

Having thus described my invention, what IIO I claim as new, and desire to'secure by Letters v Patent, is- 1, A steel car having a cover-plate extending Vtransversely under the iloorfplates above the bolster and secured to the flying transoms of the bolster on both sides of the center sill; substantially as described.
