SPECIFICATION forming part of Letters Patent N o. 678,802, dated July 16, 1901. Original application led December 11, 1899, Serial No. 739.935. Divided and this application filed March 15, 1900. Serial To @ZZ whom it may concern.-

Be it known that LCORNELIUSVANDERBILT, a citizen of the United States, residing at No. 608 Fifth avenue, in the city of New York, borough of Manhattan, county and State of New York, have invented certain new and useful Improvements in Car-Trucks, of which he following is a specification.

My invention has for its object the construction of a car-truck with as few parts as possible, and where feasible those parts are to be made of commercial shapes of iron, so as to avoid the necessity of expensive machineryin the construction of the parts, and, further, to provide a truck which may be readily and economically made and assembled and which may be kept in repair at a comparatively small expense,at the same time providing a simple and efficient structure.

The subject-matter of the present application relates to certain improvements disclosed in an application for patent for tank-car, iiled by me on the 11th day of December, 1899, Serial No. 739,935, and of which this case is a division and to which cross-reference is made.

My invention therefore resides in the details of construction and combination of parts hereinafter described and iinally pointed out in the claims.

In .the drawings forming part of this speciication, Figure 1 is a plan View, partly in section; Fig. 2, a side elevation; Fig. 3, a longitudinal sectional elevation; and Fig. 4, a sectional elevation transversely of the truck on the line .r x, Fig. 1.

The construction of the truck, as hereinafter described, maybe beneficially employed in connection with the improvements in tankcar construction shown,described,and elai med in my application for patent therefor, led .December 1l, 1899, Serial No. 739,935, of which this case is a division; but it is clear that the truck may be advantageously employed with other forms of cars. In my previously-described application I have shown and claimed a body-bolster of original construction, as at 1, Figs. 2 and 4, comprising the segmental base-web 2, lside walls 3, side flanges 4, and end and side wings 5 and 6,form ing in its entirety a segmental trough-like (No model.)

bolster, -as recited in said application, and although I prefer the construction of bodybolster any other desired form can be used in connection with the improvements in the truck now to be described.

It is constructed as follows: At 7 is the body center bearing of dish form, the annular flange 8 of which may be either secured directly to the horizontal web 2 of the bodybolsteror to a cap-plate 9, both of which may be curved, Figs. 2 and 4, to take the curve of the web 2, or flat, as in Fig. 3, the said center bearing having the downwardly-inclined web 10 and a horizontal and dishshaped crown-web 1l of the usual construction. At 12 are Wheels, 13 the axles, (the journal-boxes being omitted for elearness of illustratiom) and 14 the side frames, provided with axle-box yokes or pedestals 15. The side frames are composed of angle-iron side bars, the top chords 16 of which have an inwardlyextending horizontal web 17 and a pendent web 18. The side bars are formed with a depressed central portion 19 between the pedestals and pendent ends or arms 20 at each end, which form the outer arms of the axle-box jaws or pedestals. To complete the jaw and provide a flat bearingsurface therein for thejournal-boXes,.I have secured to the arms 20 the outer jaw-bars 21, of angle-iron, the webs 22 of which are longitudinally disposed and riveted to the pendent web 18a of the arms 20, the other Webs 23 being transversely disposed and extending inwardly to form with the usual faceplates 24, which are secured to the jaw-bar by eountersunk rivets in the usual way, the outer jaw-bar or pedestal-arm for the axleboX, the inner jaw-bar 25, with its web 26, being secured to the web 1S of the side bar, and its other web 27 provided with the faceplate 28, as already described. The web 1S forms the bearing for the seeurement of the bar 21 thereto throughout substantially the latters entire length, Fig. 3, while the jawbar 25 has only the normal drop of the web 18 for the part of its riveting-surface. For this reason the web 26 of the bar 25 is made wider, giving greater strength to resist the strain. Both the jaw-bars have their webs 22 26 cut away at oradjacentthe axle-box bottom plane IOC) to present the transverse webs 23 27 flat to the thimble 29, through which the tie-bolt 30 passes, the usual cross-bar 3l extending between the face-plates 24 28, through which the tie-bolt 30 also passes, nuts on the end of the tie-bolt securing the whole together. The lower end of the j aw-bars 21 25 are connected longitudinally (the latter directly) by the lower chord of the angle-iron, the upright web 33 of which is riveted to the jaw-bar 25, the horizontal web 34 of which being cut away at 35 to receive the web 26 of the jaw-bar. In this way but a few pieces of commercial metal are utilized to construct the side frames, which are consequently light and are of particular strength, enabling them to resist Vthe strain incidental to maintaining the parallelism of the axles and running.

Means forforming the bolster and strengthenin g the structure against torsional strains are provided as follows: Extending between the upper and lower chords 16 32 are the I- beams 3G, the lower flanges 37 of which are riveted to the web 34 of the lowerchord, thereby effectively tying the lower chords together transversely.

At 38 are compression-plates riveted, respectively, to the webs I8 and 32 of the upper and lower chords on each side of the I- beams and having inwardly-extending flanges 39, secured to the upright compression-web 40 of the I-beams. Recesses 41 and 42 are cut in the upper and lower corners of these plates to clear the flanges 37 and 43 of' the I- beams, Fig. 3. Between the I-beams further compression-plates 44 are riveted to the webs 1S 32 of the upper and lower chords and by their flanges 45 to the webs'40 of the I-beams,

the angles of the plate 44 being recessed, as at 46, to clear the I-beam flanges 3743. Plates 47 48 are riveted onto the flanges 37 43 of the I-beams, both plates tying the beams together between the ends of said beams, while the plate 4S supports a pressed-steel truck center bearing 49, the flange 50 of which is secured to the top plate48.

Extending across and between the top flanges 43 of the truck I-beain is the flanged base-plate 51 of the truck side bearings 52, made of pressed steel, preferably, (or of cast metal,) the flange 51 being riveted to the said beams, and the body-bolster 1 is provided with pendent side bearings 53, Fig. 4, preferably made of strap-iron, the ears 54 55 of which are disposed to the curve of and fastened tothe bottom web 2 of the body-bolster, the cross-web 5G bearing on the top of the truck side bearing, as shown in said figure.

The entire structure embodies lightness, strength, economy, and spacious clearances between the axle-box pedestals for the location of the body-bolster, allowing of a lowplaced car-body.
