JOURNAL-BOX.

Application led March 27, 1916.

T o all whom t may concern.'

Be it known that I, J MILLS SUMMEns, a resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Journal-Boxes, of which the following is a specification.

This invention relates to railway journal boxes.

One object of the invention is to provide a journal box which dispenses with the usual stop wedge or key placed between the roof of the box and the journal bearing or brass for distributing the load on the journal bearing and axle, but which, nevertheless, provides for the insertion and removal of the journal bearing and for its retention in proper position with the necessary clearances when supporting the load.

A further object of the invention is to provide a journal box of reduced height above the journal bearing, which permits the end portions of the truck side frame being lowered and thereby secure greater stability of the car, and at the same time provide better stress conditions in the truck side frame members as well as reducing the weight of the box. The invention comprises the construction of journal box hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a vertical longitudinal section through the improved journal box; Fig. 2 is a side elevation of the same; Fig. 3 is in part an outside end elevation and in part a transverse section on the line 3 3, Fig. 1; Fig. 4 is in part a top plan view and in part a horizontal section on the line 4--4, Fig. 1; and Fig. 5 is a vertical longitudinal section showing a slightly modified form of box.

The box illustrated is of the integral cast type, although it may be of the built-up pressed plate or composite type. It is shown as of the standard Master Car Builders type, having the body or cellar 1, side walls 2, and top or roof 3. The bottom of the cellar is curved upwardly at its forward end, as shown in Fig. 1, and is provided with the usual opening 4 arranged to be closed b v the usual lid (not shown) which will be hinged to the usual hinge lugs 5 on the top of the box. At its rear end it is provided with the usual pocket 6 for receiving the dust guard (not shown), the walls of which are provided with the open- Speccaton of Letters Patent.

ings 7 for the axle 8. All of these parts may be of the usual or standard forms.

The Improvement resides in the top or roof of the box and consists in lowering the to-p wall to bring its lower or inner face 9 down to the level of the bottom face of the usual wedge or key, and preferably also in shaping the lower or inner face 9 transversely of the box to conform to the shape of the lower face of the standard wedge, as shown in Fig. 3, as a consequence of which said top wall is adapted to rest directly upon and lit the Master Car Builders standard bearing or brass, shown in broken linesv at 10. At its rear end this top wall is bulged upwardly to form a pocket 11 for receiving the usual lug 12 at the rear end of the bearing or brass, and the side walls of the box are brought inwardly to form stop lugs 13 for engaging shoulders or notches in the side edges of the bearing and thus hold the latter against endwise displacement. While the contour of the lower face 9 of the top is substantially that of the bearing or brass 10, 1t nevertheless is so designed as to provide the usual clearances now provided between the bearings and stop wedges or keys. The outer face of the top wall is ribbed, as shown at 14, in order to provide strength with minimum weight.

For standard arch bar trucks, the box `:vill be provided with the usual journal box bolt lugs, while for the pedestal type of trucks said box is provided with ribs 16 on its side walls to embrace the usual pedestal jaws.

v The lower face 9 of the top wall is straight from end to end so as to provide a bearing along the entire length of the bearing or brass. To provide for the usualrocking movement provided for between the wedge and roof of the standard journal box, the box is so formed that it can have a slight rocking movement in the side frame. To this end the seat 17 for the pedestal frame member 18 (or the arch 'bars in an arch bar truck) is made slightly convex lengthwise of the box, as shown in Fig. 1, and the box is connected to the pedestal side frame by pin 19 extending through oval or elongated holes 20 in suitable lugs 21 on the side frame and box, and the ribs 16 which embrace the pedestal jaws are slightly iiaring toward their lower ends, as shown in Fig. 2. This construction allows the journal box to have a slight rocking movement in the frame and allows the brass or bearing to remain in alinement with the axle.

F ig. 5 shows a modification in which the top or roof is brought down so as to rest directly upon the bearing or brass so as to dispense with the usual wedge or key, but in which the journal box is of the same overall height as the standard journal boxes of the same dimensions so as to be interchangeable with present types of journal boxes. This is effected by merely increasing the depth of the ribs 14 on the outer face of the top of the box, as will be apparent by lcomparing Fig. 5 with Fig. 1. Fig. 5 also shows the box designed for arch bar types of trucks, having the curved or convex seat 17 on its top for the arch bars and a similar curved or convex seat 22 on its bottom for the tie bar.

The vbox described is practically a standard Master Car Builders box, except that the top wall has been lowered so as to adapt it to rest directly upon the journal bearing and in that way dispense with the usual wedge. This not only cheapens the box and renders it lighter, but it also reduces the height of the box and thereby permits the end portions of the truck side frame to be set closer to the ournal center than is now the practice, as a result of which the car is more stable and also better stress conditions for the truck side frames are provided.

It is obvious that the improved journal box can be either of the integral cast construction or the built-up plate or composite construction. It is also obvious that it can be designed for any type of side frame, whether of the arch bar or the pedestal type, and for any manner of securing the journal box to the side frame, whether by bolting, keying or riveting the same thereto, or forming the same integral with the side frame.

In both forms of journal box shown, the bearing can be inserted and removed by merely acking up the side frame, which permits the journal bearing being tilted up.- wardly at its outer end, relative to the axle journal, sufficiently to enable the lug on its inner end to escape from the recess 11, and enable the bearing to be slipped over the outer collar on the axle journal. With the form of box shown in Fig. 1 the connection to the side frame is such that when the side frame is jacked up the inner end of the box will drop downwardly, bringing the box to an inclined or tilted position, and lifting the box relative to the axle journal sufficiently to permit the lug 12 on the inner end of the bearing to escape entirely from the recess 11, and yproviding suflicient space above the outer axle collar to permit the bearing to be drawn outwardly in the inclined or tilted position. In the form shown in Fig. 5 the box will be lifted in parallel lines with the lifting of the side frame, but there is sufficient cutaway portion or recess in the forward end of the box in advance of the seat for the bearing to per mit the forward end of the bearing being tilted upwardly and the bearing drawn out in an upwardly inclined direction. In both forms the seat for the bearing in the roof of the box terminates somewhat inwardly from the outer axle collar, so as to give suicient space at this point to permit the bearing to be drawn out in an upwardly inclined direction.

The bearing is retained in position by means of the stop lugs 13 formed on the inner surfaces of the side walls of the box and which contact with the lugs or shoulders on the bearing, and also by the turned-up rear portion 12 of the bearing fitting into the pocket or recess 11 at the inner end of the bearing surface of the roof. The curvatures on the top andbottom faces of the box, at the seats for the side frame or the arch bars and tie bar, are sufficient to provide the nec essary rocking movement of the box to maintain the bearing in exact alinement with the axle irrespective of track irregularities, although curved surfaces are not necessary as there is ordinarily sufficient movement and clearances in truck frames to permit the box to move sufficiently to maintain the bearing in alinement with the axle.

What I claim is 1. A railway car journal box having the inner surface of its roof or top formed to rest directly on the ournal bearing and being provided with a recess in said top for receiving an upwardly projecting lug on the bearing, the forward portion of said roof being cut away in order to permit the bearing to be withdrawn in an upwardly inclined direction when the side frame with said box is lifted.

2. A railway car journal box having the inner surface of its roof or top formed to rest directlyon the journal bearing and being provided with a recess in said top for receiving an upwardly projecting lug on the bearing, and having the seat-for said bearing terminating inwardly from the outer axle collar, said box being so formed and its connection to the side frame being so arranged as to permit the forward end of the bearing to be tilted upwardly when the side frame with said box is lifted and permit the bearing to be removed in an upwardly inclined direction.

3. A railway car journal box comprising a roof and a non-separable cellar and having the inner surface of its roof formed both longitudinally and transversely to the contour of the outer surface of the Master Car Buildersstandard bearing and adapted to iit and rest directly on such bearing, the bearing surface of said top terminating inside of the forward end of the axle, said box being so formed and its connection to the side frame being so arranged as to permit the forward end of the bearing to be tilted upwardly when the side frame with said box is lifted and permit the bearing to be removed in an upwardly inclined direction.
