STAZE PATENT CHARLES A. SCI-IROYER, 01? OAK PARK, ILLINOIS, ASSIGNOR TO AMERICAN STEEL FOUNDRIES, OF CHICAGO, ILLINOIS, A CORPORATION OF NEW JERSEY.

CAR-TRUCK SIDE FRAME.

T 0 all whom it may concern:

Be it known that I, CHARLES A. SCHROYER, a citizen of the United States, residing at Oak Park, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Gar-Truck Side Frames, of which the following is a specification.

In order to make car-truck sideframes of suflicient strength to meetpresent day needs and requirements they are necessarily of considerable depth. Inasmuch as the lowest point to which the bottom of the frame may reach is limited and restricted, and since in some forms of cars it is desirable to have the side-frames as low as possible, I have invented a construction in which the springseat is at the bottom of the frame and the tension member for the central part of the frame is above the spring-seat instead of below it as is usual and customary. I am enabled, therefore, to build a side-frame lower than has heretofore been possible, and at no sacrifice of strength or rigidity. Also, my present invention contemplates changes in the general construction of the side-frame, and various other minor features of novelty and invention will become apparent to those skilled in the art from a consideration of the following detailed description and the accompanying drawings, forming a part of this specification, whereon like reference characters refer to the same parts throughout.

On the drawingsFigure 1 is a side elevation of portions of a car-truck embodying my invention; Fig. 2 is a plan view of the construction shown in Fig. 1; Fig. 3 is a top plan View of the truck side-frame with the top compression bar omitted; Fig. 4 is a section on line 44 of Fig. 1; and Fig. 5 is a vertical section on line w-w of Fig. 1.

Referring to the drawings, it will be noted that the tension member 10 of the side frame is supplied with upper horizontal ends 11, 11 adapted to rest on the tops of the journal boxes, these ends having along their longitudinal edges upstanding tapered flanges 12, 12 which approach each other at 13, 13 on the top face of the inclined portions of the tension member, and merge into the single upstanding centrally-located rib or flange 14:, the section of the inclined parts of the tension member being of inverted T- shape, as is clearly illustrated. The spring- Specification of Letters Patent.

seat 15 at the central lower portion of the side frame is at the extreme bottom thereof, its inner portion 16 being somewhat depressed to accommodate the ends of the pair of angle-bars 17 constituting the springplank or cross tie-bars. The outer elevated half 15 of the springseat is equipped with a pair of spring centering and retaining bosses 18, while on the inner half of the spring-seat blocks or plates 19 are positioned over and rest upon the horizontal inwardlyextended flanges of the angle-bars 17, and have on their top faces spring centering bosses 20, the blocks or plates being held in place by rivets or bolts passed through alined apertures in the bosses, plates, and spring-seat. A longitudinal web or vertical plate portion 21 of substantial depth and integral with the side-frame and spring-seat is located across the top face of the springseat and connects together the pair of integral columns 22, this rib or plate 21 forming in effect a connection or extension of the two portions of the strengthening rib 14. In order to make the device stronger and assist in maintaining in proper position the central portion of this rib, I provide a pair of braces 23 and 24- on opposite faces thereof, integral with the sideframe and connecting the rib with the top of the spring-seat. On its lower face the side-frame and spring-seat have a pair of spaced ribs 25 and 26, adapted to accommodate between them the usual tie-bar 27. The vertical ribs 28 on the opposite outer faces of the columns 22 at their upper ends divide into a pair of parts 29 connected across the top by a web 30, on which is adapted to rest the independent or separate compression bar 81, which at the to as of the columns is received between spacec retaining fingers 32, and which at the ends of the side-frame is received between the tapered flanges 12. As is illustrated, this compression bar 31 is riveted or bolted at 33 to the webs 30 at the tops of the columns, while the journal box bolts 34 securely hold the ends of the compression bar to the ends of the tension member or main body of the side-frame.

It should be apparent from this description and the accompanying illustration that I have provided a car-truck side-frame which is economical to manufacture, which may possess considerable depth, which at the same time is strong and rigid, and which may be readily taken apart if occasion demands, and as easily reassembled. The spring-seat of this side-frame is at practically the lowest point thereof, and because the usual strengthening rib is omitted from the bottom side of this springseat and disposed instead on top thereof, the springseat of the truck may be brought nearer to the ground than in the ordinary forms of railway car-trucks, whereby the side-frame may be given greater depth than is customary and usual.

This invention not being limited to the precise features of construction set forth, may be embodied in constructions differing in minor details from that illustrated without departing from the substance of the invention.

I claim:

1. In a railway car-truck side-frame, the combination of a tension member having a spring seat and having its tension portion at the central part of the frame located above said spring-seat, and provided with integral laterally extending braces and an independent compression member fastened to said tension member, substantially as described.

2. In a railway car-truck side-frame, the combination of a tension member having a spring seat integral therewith and adapted to accommodate four springs, said member having a tension portion at the central part of the frame integral therewith and located in the vertical plane above said spring-seat, and provided with lateral braces and a separate compression member fastened to said tension member, substantially as described.

3. A railway car-truck side-frame having a central bolster and spring opening, vertical columns, and a tension member integral with and connecting said columns above said spring-seat, the inner side of said seat being depressed to below the outer side thereof substantially as described.

4. A railway car-truck side-frame member having a central bolster and spring opening, vertical columns integral with said frame, a spring-seat at the base of said columns unitary with said frame member, a tension web or member on the top face of said spring-seat integral therewith and connecting said columns, and one or more transverse braces integral with and connecting said web or member and spring-seat, in com bination with an independent frame compression member substantially as described.

5. In a car-truck side-frame, the combination of a lower or tension member of inverted T-shape section at its central portion and channel section at its ends, said ends being adapted to rest on the journal boxes, a com pression member having ends resting on and accommodated between the flanges of said lower or tension member ends, and means to fasten together the ends of said tension and compression members, substantially as described.

G. In a car-truck side-frame, the combination of a lower or tension member of inverted T-shape section at its central portion and channel section at its ends, said ends being adapted to rest 011 the journal boxes, said side-frame also having integral there with upwardly-extended columns, a compression member resting on the tops of said columns and having ends lying on and accommodated between the flanges of the ends of said lower or tension member, and means to fasten together the ends of said tension and compression members, substantially as described.
