can-TRUCK.

To all whom, it may concern:

Beit known that I, HERBERT H. HEWITT, acitizen of the United. States, residing at Buffalo, inthe county of Erie, State of New York, have inventedcertain new and useful Improvements' i-n Car-Trucks, of which I do declare the following to be a full, clear, and

V exact description, reference being had to the, accompanying drawlng, forming part of parts incident to irregularities of the track and, compensating for any distortion of the truckafra ne in adjusting itself to the in;

equalities j of the track,

The invention consists in the novel features of construction hereinafter described,

be'connected, as shown in the drawing, by-

illustrated in the accompanying drawing and particularly pointed out in the claims at the end of this specification.

Figure 1 is a plan view showing one half of a car truck having my invention applied thereto, parts being shown in horizontal section. Fig. 2 is a view in end elevation,

parts being shown in vertical section. Fig.

3 is'a, view in vertical cross-section on line 3-3 of Fig. 2. Fig. 4c is a view in vertical transverse section on line 1 -4 of Fig.2.

In the accompanying drawing} have illustrated one half only of a car truck having my invention applied thereto. But it willbe understood that the other half of the truck will correspond in construction to that shown in the drawing. The improved side,

frame A of my. truck isshown as formed of a single casting, and the side frames at opposite sides of the truck will be connected together by suitable transverse members. Preferably, the side frames of the truck will means of a transverse'inember or transom B in such manner that the side frames may rockin vertical planes with respect to said transom. An example of this type of connection between the side frames and the transverse member or transom of the truck is shown in Letters Patent No. 1,009,747, granted to me November 28, 1911. To this end, the side frame A. is shown as formed Specification of Letters Patent.

with a large circular opening having inner and outer flanges 2 and 3 Within which is journaled the hollow, circular end 10f the transom B. In order to retain the side frame Ain secure position upon the end i of the transom, the side frame A is shown as formed with pockets 5 adapted to receive T ERIE.

suitable'keys G that maybe conveniently l heldin'place within the pockets 5 by the through segmental slots 7 that are formedin the wallof the circular end 4 of the transom B, the slots 7 being somewhat larger than The ends of the keys C project the keys C so as to permitthe slight rocking movement of the side frame with respectto the transom. .A truck bolster D is shown as a mounted above thetransom B and supported upon springs E, but these features are not essential to the present invention. sembllng the parts the side frame A will be slipped over the circular end t of the transom B and the keys C will then be placed l within the pockets 5 of the side frame and will be retained in such pockets by the pins 6, as clearly shown in. Figs. 1 and 2 of the drawing. V The journal boxes nals f of the car axlesF may havea conso i E that receive the jour struction similar, in the main, to that prescribed by theMaster Car Builders Association, the journal boxes E being provided at their outer ends with suitable lids c and.

being provided upon their interior with suitable brasses G for the journals f of the car axles. Inasmuch, however, as my improved construction of truck provides for atransverse rocklng of the ournal box with respect to the side frame, the journalbrass G may J rest directly against the under side of the top of the box. E and the use of keys or wedges between these parts may thereforebe dispensed with.

3 The preferred manner ofconnecting t-he journal boxes E to the side frame A will next be described, although I wish it dis-v tinctly understood that the pivotal connection of the journal boxes to the side frame in manner permitting the boxes to rock at right angles to, the side frame maybe accomplished in various other Ways without ole parting fromthe'scope of the invention. A

stud or journal H'extending lengthwise of the side frame is the preferred means for pivotally connecting each 1 off-the journal boxes E with the side frame and, preferably, each of the journal boxes E has a stud or journal H formed integral with one of its side walls. Each of the studs or journals H is revolubly mounted within a circular journal II of considerable length and to provide the side frame A with supplemental inner bearings 10 adapted to receive the bin cular inner end portions h of the studs or ournals H.

From the foregoing description it will be seen that when the parts are assembled, as

shown in the drawing, the journal boxes E will be free to rock or swivel in a vertical plane at right angles tothe vertical plane of the side frame of the truck. Under this arrangement the journal boxes can adjust themselves to the position of the side frame and also .to the axles or journals on which it is mounted, thus providing for a perfect alinement of the journal bearings on the journals no matter how badly distorted the truck frame may be in adjusting itself to the inequalities or irregularities of the track. This manner of connecting the journal boxes to the side frame will be found advantageous, whether the side frame be pivotally united to the truck transom or not, since,

whatever be the means of connecting the side frames of a car truck together, there is inevitably more or less distortion of the parts incident to: irregularities or inequalities of the track. By providing the journal boxes with long, or journals and by providing the side frame with supplemental inner bearings for the inner ends of said studs or ournals,a much more perfect alinement of the circular or bearing portions h and 71 of the studs or journals H in the journal bearings of the side frame is insured, thereby preventing any uneven wear or any tendency to distort the side frame. One advantage incident to formingthe side frame with open bearings at itsends to receive the studs or journals that project laterally from the axle boxes E, is that it can be readily detached from the side frames whenever it becomes necessary to change the Wheels and axles, and this, too, without removing the truck from beneath the car.

In the each ing having an enlarged central portion and upper and lower inclined, converging arms or portions which extendfrom the enlarged central portion on opposite sides of openings a and which are united at the ends of the side frame by the integral bearings 8.

preferred form of my invention,

laterally projecting studs varied within wide limits without L V I said side frames, and studs side frame comprises an integral cast-- greatest possible strength with the least.

weightand is well adapted to support the swiveled journal boxes at the ends of the side frame to resist the strains to which the frame and boxes are subjected. Inasmuch as the bearings of the side frame that-re ceive the studs or journals of the boxes are formed uponthe longitudinal central line of the side frame and between the inner and r outer faces thereof, the side frames are revers1ble and proved truckisstrong and rigid 1n construction and at the same time the journal boxes are free to rock in transverse planes without interchangeable.= The 1m distorting or straining the parts. Furthermore, the side frames, in thepreferred form of the invention can swing in vertical longitudinal planes, so that the wheel a'x-les are free to rock transversely and the wheels of the truck can, at alltimes, rest solidly upon the track, in spite of irregularities thereof. The journal boxes, while free to rock in transverse planes, are securely held against relativevertical movement upon the ends of the side frames, but in such a manner that they can be withdrawn from the side frames in longitudinal and horizontal direction, so that they can be readily detached, as stated, for repairs or the like. I

By my present invention I am enabled to use axle boxes that follow, in the main, the construction prescribed by the Master Car Builders Association, while at the same time providing for such swiveling movement of the boxes as will insure a perfect adjustment of the parts of the truck when distorted or riding over uneven surfaces.
