GAR FRAME.

Application filed February 5, 1923. Serial No. 616,993.

To all whom it may concern:

Be it known that 1, JAMES D. BENBOW, a citizen of the United States, and a resident of Aurora, in the county of Kane and State of Illinois, have invented certain, new and useful. Improvements in Car Frames, of which the following is a specification. reference being had to the accompanyingdrawings.

This invention relates to an improved construction of the frames of cars and more particularly to the frames of dump-cars of the type wherein the car-body is tilted laterally to discharge the contents thereof at one side of the track upon which the car stands. Such cars are necessarily subjected to very rough usage, and the object of my invention is to provide an improved construction and arrangement of the frame members of the carbody that will enable it to better withstand the shocks and jars incident to its manner of use. I accomplish this object as illustrated in the drawing and hereinafter par-- ticularly described. That which I believe to be newiwill be pointed out in the claims.

In the drawings, 7 I F'gQl is an end elevation of a side-dump car embodying my improvements, the body of the car being also shown by dotted lines so in a dumping position;

Fig. 2 is a horizontal cross-section taken substantially on the line of Fig. 1;

Fig. 3 is-a detail, being a perspective View illustrating the manner ofconnecting one of the vertical end bars of the car-body framewith'one of the sills. of such frame;

Fig. 4 is a view of the parts shown in Fig. 3 as seen when looking at an end of the car, as in Fig. 1; V

Fig. 5 is another view of the parts shown in 4 as viewed from the right-hand side of said Fig. 4:, some parts being in section; and n Fig. 6 is a horizontal section taken at the line 6-6 of Fig. 4. I

Referring to the several figures of the drawings,10 indicates a car-truck, the two wheels thereof that are shown being indicated by 11. Pivotally mounted upon the car-truck is a car-body, here indicated generally by 12, and pivotally connected in any suitable way with the truck to adapt it to be tilted so as to discharge its load at one side. The type of car illustrated is one wherein the body may be dumped at either CFI side, and the gates at such sides are indicated by 13. Such gates are automatically operated by the movement of the tar-body through a lever system at each end of the car, which may be as here illustrated or otherwiseall of such mechanism being well known, and therefore not needing description.

Turning now to the features which characterize my invention, let indicates a plurality of longitu(finally-extending sills beneath the floor of the car, two of such sills in the construction shown being provided at each side of the longitudinal center of the car. Each of these sills has a general resemblance to an ordinaryI-beam but, differing from such I-beams in that the upper and lower heads or flanges are considerably wider, and consequently give to the beam an appearance that in cross-section more nearly resembles the letter H, andI shall, therefore, designate them ti-shaped sills or beams. At

each of its outer ends each of these longitudinally-extending H shaped sills has its upper head or fiange cut away at one side of the vertical web of the sill so as to provide a rectangular notch, as best shown in Fig. 6 at 15. 16 indicates vertical, frame bars, one being connected with and rising from each end of each of the said H shaped sills. Each of these vertical bars 16 is so formed as to provide an intermediate portion from which project laterally oppositelydirected flanges whereby the bar in crosssection approximately resembles the letter Z, and willtherefore be hereinafter referred to" as Z-shaped bars. Each Z-shaped bar is of a size to fit snugly in one of the notches 15, with the result that, as clearly shown in Fig. 3, one of its turned members lies opposite and against the central portion of the H-shaped sill. When the Z-shaped bar is so locateed then it will project down far enough so that the ends of its two parts that lie Within the notch 15 rest upon the lower head of the sill, as clearly indicated in Fig. 3, and with its outer part that lies opposite the end of such sill extending completely over the web of the sill. This construction of the sill 14: and the vertical bar 16 enables them to be riveted together by means of rivets 17 that pass through the wide web of the sill and through the central portion of the bar 16, and also enables the firm riveting thereto of a heavy angular bracket 18,

' bracket and'through the upper head of the sill passes a rivet 19, while the vertical wall of the bracket is secured to the central por. tion of the Z-shaped bar 16 by a rivet 20. The parts 14 and 16 are additionally secured together and the several sets of frame members 14 and 16 connected together by the riveting thereto of an angle-iron cross-strip 21 which rests upon the upper heads of the several sills 14 and to which sill-heads the cross-strip is riveted by rivets 22other rivets 23 securing the other flange of the strip 21 to the adjacent member of each z-shaped bar. The lower edge portion of th end wall 2 1 o1 the car-body is interposed between the cross-strip 21 and bar 16, as shown in Fig. 3, and is there secured by the rivets 23. As shown in Fig 1, this wall 24 is further secured by other'rivets 25 that pass through it and the adjacent turned sections of the bars 16.

From the foregoing description of the con struction and arrangement of the longitudinal sills and the bars that rise therefrom,

it will be seen that a construction of frame is provided that is exceedingly strong, and that by reason thereof the car-body as a whole will be so braced and heldas to be adapted to very strongly resist the destructive effects of the shocks and jars to which the rough usage of these cars constantly subject them.

What I claim as my invention and desire to secure by Letters Patent, is V 1. A car-frame comprising a metal sill consisting of an H-shaped beam having an angular notch in itsupper head at onevside of its central web, in combination with an approximately Z-shaped vertical bar seated in said notch with its central portion lying against and secured to one face of the central web of the beam and one of its members extending over the end of said web.

2. A car-frame comprising in combination a metal sill member consisting of an H: shaped beam having an angular notch at an 3. A car-frame comprising in combination a metal sill consisting of an H-shaped beam having an angular notch in its upper head at one side of its central web, an approximately Z-shaped vertical bar seated in said notch with its central portion lying against and secured to one face of the central web of the beam and one of its members extending over the end of said web, and an angular bracket lying upon and secured tothe upper head of the beam and also secured to said vertical bar.

41. A car-frame comprising a plurality of metal sills each consisting of an H-shaped beam having an angular notch in each end of its upper head at oneside of the central web of the beam, in combination with a plurality of approximately Z-shaped vertical bars each seated in one of said notches with its central portion lying against and secured to oneface of the central web of the adjacent beam, and means extending over and secured to said beams and also secured to said bars. a

5. A car-frame comprising in combination a. plurality of parallel sills each consisting of an H-shaped beam having an angular notch in each end'of its upper head at one side of the central web of the beam, an approximately Z-shaped vertical bar seated in each. of said notches with its central portion lying against and securedto one face of the central web of the adjacent beam, and an angular cross-strip resting upon and secured to the upper heads of the several beams and also secured to each of said vertical bars. 7 1 7 JAMES D.
