RAILWAY-CAR UNDERFRAME.

Specification of Letters Patenti. Patented M31'. 15, 1910.

Application led October 28, 1909. Serial No. 525,145.

i To all whom 'it `may concern:

Be it known that I, JEROME Gr. Bownii, a

` citizen of the `United States, residing at Chicago, in the county of Cook and State oflllinois, have invented certain new and useful Improvements in Railway-Car Underframes, of whichtthe following is a specication. i An object of the present invention is to provide an improved bolster, center and `draft sill construction for railway cars,

which construction is especially designed to permit of its being manufactured independently of the remaining portions of the car and applied thereto or to an existing car without necessitating the complete disassembling of all of theparts of the car construction, but, when applied to an old car, necessitating only the removal of the old bolster, center andldraft sill construction for which it is to be substituted.

The construction may be used in connection with new cars, but4 is especially designed t for the purpose of supplying existing old cars, such as old wooden cars, with a metallic backbone and underframe. y

The invention is fully and clearly de`- scribed in the accompanying specification )and shownonthe accompanying drawings,

in which like reference characters refer to `like parts, and inwhich Figure l is a `plan View of the construction, showing also a portion of a car bolster; Fig. 2 is a side elevation of the same, showing the car end sill and a portion of the car end wall in section; Fig. 3 is a front eleva- Htionrof the structure shown in Fig. 1; Fig. .y 4 is a transverse section of the same at the showing a slightly modified construction.

such car.

bolster' point;"and Figs. 5 to 8, inclusive, are views similar to Figs. 1 to 4, respectively,

Referring now in detail to the drawings, and to the construction shown in Figs. 1 to y 4, inclusive, 1 represents the center sills, 2

the endsill of a car to which the underframing is to be applied; 3 the end wall of 4 are the draft beams which are the equivalent of the draft timbers of old wooden car construction, the same being located in "a lower plane than the center sillsl, and being adapted to carry the draft gear of a car. Draft beams 4 are provided with the usual draft lugs 5. 6 is the web, 7 the lower tie member and 8 the upper tie lmember of the bolster. Veb 6 is provided with a central depression 6a. la is the bottom cover plate connecting center sills 1. 9 is a central angular strut, plate or spacer riveted or secured to the iianged web plates 6 and also riveted or secured to the upper tie member 8 of the bolster.

Center sills 1, shown in the drawings, are of channel form, one of the draft beams 4 being riveted to each of said channels. Draft beams 4 are provided at their` inner ends with narrowed extensions 4, the upper edges of which are dropped below the horizontal plane of the upper edges of the forward portions of the draft beams 4. Draft beams 4 are spaced by transverse plates 41 and bythe lower.cover plate 1a of the center sills 1; at their forward ends draft beams 4 may beV suitably shaped to provide a seat 4b for the end sill of the car, for which purpose they project forwardly beyond the center sills 1. Seat 4b may be stepped as shown in the drawings.

The special formation of the extensions 4a `of the draft beams 4 provides a space, when the draft beams 4 are riveted to the center sills 1, to receive the upper tie member '8 of the bolster. This space is closed by a filler 10, and securing bolts 11 or other suitable `mea-ns are pass-ed through the lower flanges ofcenter sills l, through the fillers 10 `and through the upper flanges of the extensions 4a. The lower flanges of the extensions 4a are turned to conform to the shape of the upper flanges of the web plates 6 of the bolster at the recess points, and when the parts are assembled, the extensions 4a rest in the recesses in the bolster and formstruts between the upper tie member 8 and the upper flanges of the web plates 6.

12 are bolt-eye-plates on the center sills 1 in line with the center of the upper tie member 8 of the bolster when the parts are assembled, and 13 are similar eye-plates on the draft beams 4 in line with the plates `12. 14 are bolts extending through the upper tie member 8, the bottom cover plate la of the center sillsl and through plates :12.

The fillers 10 with their securing bolts l1 and bolts 14 are designed to securely lock the bolster to the center sills and draft beams. When the parts are assembled it is preferable to first rivet the center sills 1 and the draft beams 4 to each other. The upper tie member 8 of the bolster is then inserted in the recesses formed between the extensions 4a and the center sills 1, and bolts 14 are passed up through plates 13, tie member 8, the bottom cover plate 1a and plates l2. The nuts having been applied to bolts 14, the fillers 10 and their securing bolts 11 are then inserted, after which the web member 6, the lower tie member 7 and the central struts 9 may be applied and riveted or secured together, after which the framing is ready for securing the superstructure of the car thereto. It will be noted that the center sills, being located in a horizontal plane above the upper tie member 8 of the bolster, form securing means for the car superstructure against lateral shifting of said superstructure on its underframe, as the stringers and the side sills of the superstructure will be in substantially the same horizontal plane as the center sills 1 when the underframe is applied to the car. It will also be noted that the end sills 2 of the car, being in substantially the same horizontal plane as the center sills 1, the car is also secured against longitudinal shifting relative to its underframe. It will also be seen from Figs.- 1, 2 and 3 that the boltA eye-plates 13 areextended or flanged horizontally and riveted to the bottom cover plate 1a of the centerV sills, thereby increasing the stiffness of the construction.

The form of construction as shown in Figs. 5, 6, 7 and 8 differs but slightly from that shown in Figs. 1 to 4, inclusive, the

sole difference being that the draft beams 4 are extended upwardly and riveted to the inner face of the webs of the center sills 1; the recess for receiving the upper tie member 8 of the bolster being formed by longitudinally cutting or recessing the draft beams 4, and the upper anges of the extensions 4a being formed by separate angles 4c which are bolted through spacers or fillers 10 byl bolts 11 to the lower flanges of the center sills 1. The end of this recess is reinforced and each center sill 1 and draft beam 4 are further secured to each other by a vertical plate 4e which is riveted to sill 1 and beam 4. This plate is designed to receive and transmit end shocks from and to upper tie member 8. The forward end of the draft beams 4, which project beyond the center sills 1, are also formed by cutting, and the seats for the end sill 2 are formed by sepaconstruction shown in Figs. 5 to 8, inclusive, employs a top cover plate 1b instead of a bottom cover plate la, as shown in Figs. 1 to 4, inclusive. In other respects the construction is the same as that shown on Figs. 1 to 4, inclusive, and the method of assembling is the same.

An important advantage of both forms of construction herein shown is that it enables the disassembling of the parts for the purpose of repair or replacement.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:
