CAR-TRUCK.

To all whom it may concern.

' Gar-Trucks, of which the following is a.

full, clear,and exact description.

This invention relates to six wheel trucks forrailway cars, and the objectcf the invention is to provide a truck in which wheel-pieces, pedestals, equalizer bars and their necessary adj uncts' are dispensed with.

\ The invention consists of articulatedside frames, carrying the axle-boxes; a truckbolster having four arms extending through openings in the side-frames and engaging such frames, and supported on springs which are arranged in the openings in the side-frames: also side-bearings supported from the bolster-arms; also brake-beam suspension arrangements. and also brake-beam connections for simultaneously operating the brakes, all we will proceed now moreparticularly to set forth and finally claim.

It will be understood that we do not wish to limit our invention to the particular details of construction shown in the accompanying d'awings, as various changes may be made without departing from the spirit of the invention.

In the accompanying drawings, illustrating the invention in the several figures of whiclrlike parts are similarly designated,

'l igure 1 is a side elevation of a truck embodyingz one form of the invei'itiou. Fin. 2 IS a top plan view showing thebrake mechanism partly in dotted lines. Fin; 1 is a sec-.

tional elevation taken in part on the line A B, Fig. 2. Fig. i is a vertical transverse section taken in the plane of line C I), Fig. 1. Figs. 5 and 6 are detail views showing in elevation and plan the type ,of side frame members shown in Figs. 1, 2, 3 and 4. Fig. 7 a top plan view, partly in section, showing another form of articulated side frames and another method of hanging the brakes. Fig. 8 is a sectional elevation, taken in part in the plane of line E F, Fig. Fig. 9 is a detail view of the type of articulated jointshown in Fig: 7.

It to be noted, at the outset, that we dispense with wheel-pieces, pedestals and equalizer-bars as such, and replace these with a pair of articulated side-frames on each side of the truck, which receive the Specification of Iietters Patent;

Patented Mar-.4, 1913.

Application filed September 6, 1912. Serial No. 718,910.

bolster, the axle boxes andthe springs, and when assembled perforln the functions of equalizer-bars in distributing the load.

Theaxles 1, 2 and 3, and their pairs of

wheels

4, 5 and 6 and the axle boxes 7,8 and .9, may be of any usual or approved construction.

The side-frames are composed of pairs of

members

10 and 11. connected at adjacentends by suitable knuckle joints, two forms of which are shown. The knuckle joint shown in Figs. 1 to 5, comprises

circular flanges

12 and, 13 projecting laterally to ward each other and of a size to fit or nest one within the other, and a connecting bolt 14... As shown in Figs. 7 to 9 the knuckle joint is composed of a socket 15 in one memher and a cross pivot 16 on the other niember adapted to fit in the socket and requiring no other connection. The member 10 is provided at its outer end with a recess 17 to receive the axle-box 7, and an overhanging arm 18, to which the axle-box may be secured by'ordi'nary bolts 18*; and if de sired, a strap 19 may be arranged beneath the axle-box to receive it and the bolts 18 and itself be secured to orvformed with the member 10. The inner end of this member 10 is made or provided witli a projection 20 and to this is secured the intermediate axle-box 8, by bolts 21, or otherwise. In this instance, also, a bo-ttoinstrap 22 may receive the axle-box and its bolts and itself be secured to or formed with the member 10. Thus themembers 10 on opposite sides of the truck receive and support the four axl.e boxes of one outer axle and the intermediate axle. The third axle 3 is supported in the axle-boxes 9 and these boxes are secured in recesses 23 made in the outer ends of the members 11, and secured to theoverhanging arms 2t by bolts 25 and straps 26 formed with or attached to the members.

Thus, all of the axle-boxes are sustained the bolster. These side-frames may be cast.

The bolster 29 is, preferably, a single casting, of platform formation, having the center-bearing element- 30, and at each corner laterally projecting arm 81, each arm 7 ending in a longitudinally extending spring pocket 32 which is provided with guides 33 to engage and cooperate with the guides 28,

to connect the side-frames on opposite sides of the truck and provide for relative vertical movement. Between the arms of the bolster and the openings in the side-frames are springs 34, and these springs may be supported in the openings upon suitable integral or removable spring pockets 35. Thus the side-frames and bolster may be united and the parts held 'in alinement without the use of cross-ties, although such ties may be added if desired. The sidebearing plates 36 may be mounted upon bars 37 fixed to the arms of the bolster outside of the side-frames.

With the arrangement shown and described, the side members 11 and their wheels and axle become in effect a trailer, and by virtue'of their articulation or pivotal relation to the other members 10 they may respond freely to track and load conditions. The construction described requires modification of the brake mechanism, and we have shown two modes of arranging such mechanism. I

In the construct-ion shown in Figs and 3, we have shown the brake-beams as supported entirely from the side-frames. In this case the side-frames 10 have later allyprojecting supports 38 from which depend stirrup-like links 39 connected with the brakes for the intermediate pair of.

wheels 5, while the

brakes

50 and 51 for the outer pairs of wheels are connected by

links

52 and 53, respectively. In other words, the brake-beam for the intermediate wheels is supported from above, while the brakebeams forthe outerpairs of wheels are supported from below, and in this latter case it may be necessary to use springs substantially as indicated at 54 and 55, to pull the brake-beams away from the wheels. The operating mechanism may comprise a dead lever 56 fulcrumed to the bolster through a pivotal connection 57 and having its lower end connected by a pivotal connection or link 58 with the. brake-beam for one of the outer pairs of wheels, and having its upper end connected by a rod or tension member 59 with the upper end of a floating lever Gt) which is connected between its ends by a pivotal connection 61 with the brake-beam of the intermediate wheels, and has its lower end eonneeted with one end of a compression member (352. the other end of which compression member is connected with the lower end of a floating lever (33 which is connected between its endsby a pivotal eonnection (34 with the brake-beam of the other outer pair of wheels, and hasits upper end connected in any suitable way with the brake-operating mechanism.

In the construction shown in Figs. 7 and as 8, the brake-beams are hung directly from the bolster by the several links 65, and the operating mechanism is essentlally'the same as that already described with reference to the construction shown in Figs. 1

to at, excepting that the dead lever has a 70 bracket-like fulcrum 66 which is arranged at the outer end of the bolster.
