JOHN TAYLOR, OF- TROY, NEIV YORK.

CAR-TRUCK.

SPECIFICATION forming part of Letters Patent No. 455,990, dated July 14, 1891.

Be it known that I, JOHN TAYLOR, of Troy, the county of Rensselaer and State of New J by declare that the following is a full, clear,

and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification, in which Figure, 1 is a half side elevation and half Sectional view of my improved car-truck, the line of section being indicated by line ,2 2. Fig. 2 is a plan View thereof. Fig. 3 is a double central transverse vertical sectional view thereof on line yy, Fig. 2, the respective part sections being distinguished by line 00 w. Figs. 4, 5, .6, and 7 are detail views of the castings G. vFigs. 8 and 9 are details of a center brace.- Fig. 10 is a detail View of a lower casting B.

This invention is an improvement incartrucks; and its objects are to produce a truck having an open center between the wheels, and strong, simple in construction, and easy riding; and to these ends it consists in the novel construction and combination'of parts hereinafter clearly described and claimed. Referring to the drawings by letter, A A designate the side beams of the truck, which are preferably composed of parallel bars a a, set edgewise and united by transverse bolts, which pass through sleeves or castings interposed'between the bars a, as shown.

B B designate the castings secured between the bars at the ends of the beams. These end castings have a vertical portion Z), which i is laterally perforated for the reception of bolts a, which secure them to the bars, and they depend below the beams somewhat and have lateral inwardly-projecting extensions B which are flanged on the upper side edges to receive ends of bars 0 C, that constitute the ends of the truck and unite the side beams, as shown. On the lowerside of extension B is a pair of depending perforated ears B between which the brake-suspendinglink Z is hung, and a depending perforated trans verse flange B to which is bolted the upper end of the fender-supporting iron Y. The

portion b has a depending socket portion b Application filed November 28, 1890. Serial No. 372,919. (No model.)

- which inclines inwardly toward the journalboX casting, but is closed at top.

17 is a tap-bolt through portion 1), entering the bore of the socket. The journal-box cast ings D are bolted to the side beams near the ends thereof, as shown, and the lower ends of the jaws d of the castings are connected bya transverse bar D. On the outer sides and lower ends of jaws (Z are formed upwardlyinclined sockets cl, in which are set the lower ends'of inclined braces E e. The upper ends of outer braces E are engaged in sockets b of castings B, while the upper ends of. inner braces e are engaged in similar but oppositely-inclined sockets f, formed in castings F, that are secured between the members of the beams, as shown, about centrally between boxcastings D. By this construction the ends and centers of beams are strongly braced from boxes. The castings F are formed with transverse sleeves, through which pass bolts uniting bars a G designates castingshaving a centralcap portion 9 and opposite sleeves g, united to the cap by lateral webs, and from the Websthereot' depend lugs 9 which are lipped under the side bars of the beams, as shown in Fig. (5,to relieve shearing strain on the bolts, which secure the castings tothe members of the beams between the members of the journal-box castings and above the j on rnal-boxes, and coiled springs II are interposed between the boxes and caps g, thereby supporting the frame on the axles, as indicated. In detail Fig. 7 this cap is enlarged and bars a bent accordingly to accommodate springs of greater diameter. t

I I designate a pair of channel-bars that are secured to the side beams about centrally and transversely of the frame.

so that the bodies thereof are above the plane of the frame. I

J J designate metallic castings attached to The ends of 1 said bars are bent downwardly, as indicated,

the side beams between the ends of bars I I4,

and rising slightly above said bars. These castings J are provided at bottom with laterally-projecting flanges J, which overreach the ends of bars I, and A A are bolts transfixing flanges J, ends of bars I, the beams and the castings J, as indicated, and when from bars I by hangers M M near the sides of the truck, the upper ends of which irons pass through openings in bars I and are secured by nuts m, and washers m are interposed between the nuts and bars. The stirrup-blocks depend barely below the beams.

N N designate springs supported on the stirrup-blocks below" bars I and transversely; thereto, and on these springs is supportedthe bolster K, which lies transversely of the truck between and above bars I. The bolster is secured to the springs by clip-irons kand nuts The ends of the irons pass through perforated ears 0 0 of chafing-plates O, resting on the bolster, and secure said plates to the bolster and the latter to the springs.

P designates the king-bolt secured ecu-- trally to the bolster by plates 19 and bolts J.'

R designates a channel-iron bar, which is pivoted on said bolt, being provided with suitable chafing-plates, and its ends are bolted to angle-iron S, secured to the side sills of the car-body. By this construction the body-bolster R is carried up between the sills of the body, thus lowering the body nearer the rails. To further support the sills of car truss-rods t are arranged on the sidesof barR and parallel therewith, being supported at center on a.

chair-casting T, and their ends pass through the sills and are secured thereto by lipped washers and nuts, as shown.

the transverse and longitudinal mot-ions permitted the bolster without interfering with the movements of the truck-frame, the arrangement of spring whereby the bolster and frame are amply cushioned and yet an open.

center left between the wheels, so that electric motors can be conveniently attached to the truck; also the wheels can be set close together and the body of car is lowered, reducing the height of car-steps.

The invention is designed more particularly for double truck-cars. If it is desired to further stiffen the side beams, truss-rods V may be used, as shown in detail, Figs. 8 and 9. These rods are suspended between the members of the beams, being attached to the castings G or to bolts secured to the beams, and at center they support an upright stud-bolt e, which centrally sustains a plate attached to the beam between bars I, or bolt 1: may be connected directly to castings F. The bolts '0 are provided with adjusting bolts and nuts for regulating the tension on the truss-rods.
