FRANKLIN L. BARBER AND EDWIN W. WEBB, OF CHICAGO, ILLINOIS, ASSIGNORS TO STANDARD CAR TRUCK COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF NEW JERSEY.

UNDERFRAME FOR CARS.

Specification of Letters Patent.

Patented Jan. 26, 1915.

To all whom it may concern:

Be it known that we, FRANKLIN L. BAR- BER and EDWIN W. WEBB, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Underfra-mes for Cars; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to steel frame cars and has for its object to improve the underframe structure thereof.

Generally stated, the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

In the accompanying drawings which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings: Figure 1 is a horizontal section taken approximately on the line :0 c on Fig. 3, some parts being broken away; Fig. 2 is a transverse vertical section taken approximately on the line @12 m on Fig. 1; Fig. 3 is a vertical section taken approximately on the line 00 m on Fig. 1; and Fig. 4 is a fragmentary view in elevation, showing the central portion of the front end of the improved underframe structure.

The underframe structure of the car comprises side sills 1, center sills 2, end sills 3 and body bolsters 1, all of which parts are preferably constructed from commercial rolled steel, channels or angles, and sheet metal web plates riveted thereto. Also, of course, the said elements are rigidly connected together, preferably by suitable tie plates and connecting rivets, certain of which are designated by the numeral 5 on Fig 1. Horizontally disposed rectangular sheet metal plates 7, preferably of steel, are riveted or bolted at their edges to flanges of the end sills 3, body bolsters 4:, draft sills 6 and ends of the side sills 1. These plates 7 very greatly reinforce the girders made up of the said elements 1, 3, 4 and 6. It is here highly important to note that the said reinforcing plates 7 are located in the horizontal plane that approximately intersects the draft sills 6 at their central portions. In other words, said plates 7 are located about midway between the upper and lower flanges of said sill 6, (see particularly Fig. 2.) The connections between the plates 7 and sills 6, is preferably made by angle bars 7 riveted thereto and to the webs of the said draft sills 6. The outer edges of the said plates 7 are riveted, or otherwise rigidly secured to the lower flanges of the side sills l and end sills 3. This throws the end sills 3 above the reinforcing plates 7 so that the draw bar of the coupler will work below the said end sill and not require cutting into the latter. By this novel arrangement of reinforcing plates 7, the draft sills are anchored in the trussed girder in such way that draft and bumping strains will be most efliciently resisted, and there will be a minimum tendency of the said draft and bumping strains to force the said draft sills out of true horizontal positions. It will be noted that the depending intermediate portions of the bolsters 4 are dropped down to the lower flanges of the draft sills and their lower flanges are tied to the lower flanges of the said draft sills by metal tie plates 4? riveted to the flanges of both thereof. The top flanges of the draft sills 6 are connected bya tie plate 6 preferably riveted thereto. The draft sills 6 are not only very securely anchored to the entire girder but are incorporated as parts of the girder and utilized as the strut members thereof. F orwardly converging reinforcing angles 8 are shown as riveted to the plate 7, and further stiffen the girders. In Fig. 1, the plates 7 are shown as provided with large perforations or holes 9 which will prevent water from accumulating on the same.

As shown, the sides 10 of the car body or hopper, the oblique bottom 11 and trap doors 12 are all metallic structures, preferably made up of sheet steel and rolled steel reinforcements of one form or another. As these features, however, constitute no part of the invention, they may be briefly noted as above.

In Fig. 3, the numeral 13 indicates a truck bolster having a suitable center bearing plate 14 pivotally connected to a center bearing 15 rigidly secured to and depending from the central portion of the coiiperating body bolster 4:. Also in Fig. 3, certain of the car wheels are diagrammatically indicated by the numeral 16. Preferably, a cast coupler guiding yoke 17 is bolted, or otherwise rigidly secured to the end sills 3 and to the front or outer ends of the draft sills 6.

While the improved underframe structure described is shown in connection with a car of the gondola or hopper type, it will, of course, be understood that it is capable of general use in steel or metal frame car structures, nevertheless, the novel under frame structure is especially well adapted for use in connection with cars of the gondola or hopper type, in Which construction the body bolsters are extended high up Where they afford eiiicient supportsfor portions of the inclined bottoms of the hoppers.

What We claim is:

1. An underframe structure for cars comprising side sills, end sills and body bolsters connected and braced to form horizontally disposed girders at the ends of thecar, draft sills connected to said body bolsters and end sills and affording reinforcing struts to said girders, and horizontal reinforcing plates on the opposite sides of said draft sills rigidly connected to said side sills, end sills and'bolsters and reinforcing the said girders, the said reinforcing plates being located in hori zontal planes that intersect said draft sills approximatelymidway between their upper and lower edges.

2. An underframe structure for cars comprising si'desills, end 'sillsand body bolsters connected andbraced to form'horizontally disposed girders at the ends of the car, draft sills connected to said body bolstersand end sills and affording reinforcing struts to said girders, and horizontal reinforcing plates on the opposite sides of" said draft sills Copies of this patent may be obtained for rigidly connected to said side sills, end sills and bolsters and reinforcing the said girders, the said reinforcing plates being located in horizontal planes joining said side sills and end sills at their'lower edges and intersecting and joining said draft sills approximately midway between their upper and lower edges, all of the said parts being of metal.

3. 'An underframe structure for cars comprising side sills, end sills and body bolsters connected and braced to form horizontally disposed girders at the ends'of theca'r, draft sills connected to said'body bolsters and end sills and affording reinforcing struts tosaid girders, horizontal reinforcing plates on the opposite sides of said draft'sills rigidly connected to said side sills, end sills and bolsters and reinforcing the said girders, the'jsaid reinforcing plates being located in horizontal planes joining the said side sills and end sills at their lower edges and intersecting and joining said draftsi-lls approximately midway between their upper*"and' lower edges, all of the said parts being of metal, horizontal tie plates connecting the upper edges'of said draft sills'and spanningthe space between the same, and draft bar guide yokes secured to the intermediate portions 0f said end sills.

In testimony whereof We affix our signatures in presence of two Witnesses. FRANKLIN L. BARBER.
