JOHN A. PILCHER, or sea ns, aerum RAILWAY-CAR TRUCK.

Application filed August 13. 1am: ser l uof iemsa.

To all whom it may concern Be it known that 1, JOHN A. PILC'I-IER, a citizen of the United States, residing in the city of Roanoke, and in the county of Roanoke, State of Virginia, respectively, have inventedlcertain new and useful Improv ments in Railway-Car Trucks, of which the following is a specification.

This inventionrelates to side framesfor 'ailway car trucks and journal boxes'therefor.

l One object of the invention is to provide a truck side frame and a ournal box therefor so constructed as to reduce theheight of the journal box and tobring theside rame down low relativeto the center of the axle.

Another object. of j the invention to provide an improved form of construction of a journal box which obviates the necessity of employing a key or wedge for holdingthe journal hearing or parts in proper position j in the box.

()therand further important objects of the inventionwill be apparent, from the disclosures in the drawings and specification.

The invention (in a preferred form) is illust-rated in the drawings and hereinafter more fully described. x

Figure lis abroken side elevation of the preferred form of side frame and journal box. The journal box is shown one half as an end view from inside the side frame and one half as an end view from outside of the side frame.

Figure 2 is a side elevation of the )Olllllfll box showing the end frame in end elevation.

F igure 3 is a section taken approxii'i'uitely on the line 33, Figure 2.

Figure 4. is a section taken approximately on the line ls Figure 1, illustrating the manner in which the bearing is placed in or removed from position.

Figure 5 is a broken side elevation view showing the manner in which the side frame portion of the side may be raised relative to the journal box, I when the wheel, bearing or other parts have become worn.

Figure 6 is a section taken approximately r the dust 2.being formedjntegral with or attached to ner end of the box is provided with an e.n. i

larged portion8,having aguideway 9 for guard (not shown in the drawi-ngs)'. i y

Disposed at either' side of the journal box, there is a seat or bearing 10 for receiving theload .from theside frame 11. Depending downward from theside frame 11, below the top of. the journal boxon either side thereof, are the arms or

projections

12 and 13, which rest on. the seats 10 of the journal box. These projections, or arms, 12 and 13, not only serve to transmitthe load from the side frame to the journal box, but also serve to hold'thejournal box in a fixed position relative to the side frame, longitudinally of the truck.

Both the seat-s10 on the journal boxandthe bearings .14. .on the

side frame projections

12 and 13, arecurved or semi-cylindrical in form. VVhilethe seats 10 on the box and the bearings lion the side frame are shown concave upward; they-may. be formed concave downward without interfering with the functioning of oneon the other. lvhenever the parts of the truck; wheels, bearings, etc. become worn, permitting the side frameand car to move downward, they may be raised by applying one or. more liners 15 between the seats 10 on the box and the bearings 1-1 on the side frame, as shown in Figures 5 and 6. The

projections

12 and 13 of the side frame 11 are provided with lips or extensions 16, which serve to keep the liners 15 in position.

The side frame 11 is operatively attached to the journal box by means of the bolt 17. The side frame is provided with one or more holes 18 opposite which. are vertical elongated openings 19 in the journal box. Thus when one or more liners are applied between the side frame and the box, the,

bolt 17 may be placed in the hole in the side frame. which is in line with the bottom the box, thereby permitting the side frame to be readily and easily raised relative to the box. The openings 19 in the box are 4. The' load is transferred from the side walls 3 and 4 through the top wall 1, direct to the bearing 19, which is the American Railway Association standard journal bearing. The inner side of the top wall 1 is formed to receive the upper angular surface of the bearing 19. The top wall 1 is provided on the outer side with ribs orstiffeners 20, which reinforce the top of the box. On the inner side of the top wall 1 there are provided ribs 21, which reinforce the top wall 1 and also position the bearing 19 on top of the axle. The lugs 22 on the bearing 19 bear against the ribs 21 in the box and prevent the bearing from moving inwardly. i

The bottom wall 2 of the journal box is inclined upwardly towards the inner end of the box so that when the box is jacked up with a horizontal faced jack it will rotate about its inner end, taking the position shown in Figure 1. In this position the bearing 19 may be readily and easily removed or placed, in position.

By having the bearings for the side frame on the sides of the box rather than on top and not employing the ordinary key or wedge, the end of the side frame is brought down low relative to the center of the axle. Further, the load being transmitted to the box on the sides thereof rather than on the narrow top, stabilizes the box 'in the side frame under the action of the brakes and forces other than the direct load.

Thus I have provided a truck side frame and journal box construction in which the bearing may be readily and easily removed or placed in position and also, one in which the wear of the bearings, wheels, or other parts of the truck may be taken up. Furthermore, I have provided a construction in which the end of the frame is positioned low relative to the center of the axle.

There may be various"modifications of the invention, and it is my intention to cover all such modifications which do not involve a departure from the spirit and scope of the following claims I claim:

1. In combination with a truck journal box, a side frame resting on arc shapcd seats disposed at the sides of the said journal box below the top thereof, liners interposed between said side frame and said are-shaped s-oats on ournal box for adjusting the height of said side frame relative to the journal box. 7 V

2. In combination with a truck journal box, a sidefran'ie resting on arc-shaped seats disposed at the sides of the said journal box below thetop thereof, liners interposed between said side frame and said arc-shaped seats on journal box, projections on said side frame for-holding saidline'rsin position.

3. In combination with a truck side frame, a journal box having vertical bearing surfaces at the sides thereof for holding it in a fixed position relative to said side frame, longitudinally of the truck and horizontal bearing surfaces at the sides and below the top thereof,whereby said box may rock on said side frame transversely of the truck, the said vertical bearing surfaces and the said horizontal bearing surfaces being so formed that said side frame may be lifted off said journal box in dismantling the truck.

In testimony whereof I affix my signature;

JOHN A. PILOHER.
