\ TRUCK PEDESTAL.

Application filed March 10,1927. Serial No. 174,271.

My invention relates to railway rolling stock and consists. in an improved truck pedestal structure. It has been proposed to utilize anti-friction bearings for supporting the load on railway rolling stock journals, and where antirfriction boxes have been designed their width has necessarily been great enough to accommodate the rollers, balls, or other anti-friction elements surrounding the journal. In the ordinary .bearing construction now in general use, the arcuate brass resting upon the upper surface of the journal does not extend laterally beyond the sides of the journal and the width of the journal box is only-slightly greater than the diameter of the journal. As the pedestal legs ordinarily are only spaced far enough apart to accommodate the box between them, the substitution of anti-friction bearing boxes for the standard journal boxes would require'the add greatly to the expense of making the change from one type of box to the other. be particularly so where the desirable onepiece cast steel truck frame with integral pedestals is in use,-as in such cases it would be necessary to scrap the entire frame and replace the same;

In my. copending application Serial No. 174,272, filed March 10, 1927,1'illustrate and describe a pedestal structure having parts which may be detached to provide a wider jaw.

The main object of my present invention is to provide a one-piece pedestal structure which will mount a standard journal box in the usual manner and is adapted to be modified so as to accommodate the wider anti-friction journal box. In the accompanying drawings which illustrate my invention Figure l is in part a side elevation of,

' and in part a longitudinal vertical section through, a four wheel car truck, the frame of which includes an integral pedestal struc ture of the type mentioned above, and. illustrating respectively the mounting of both types of boxes. I

Figure 2. is a detail horizontal section taken on line 22 of Figure 1.

Figure 3 is aJsimila'r section taken online 3-3 of Figure 1. v H

Figure 4 is in part a side elevation of, and inpart a longitudinal vertical section use of This would through, a separate pedestal, possessing similar features to. the pedestals illustrated in Figure 1.

Figure 5 1s a side elevation of a separate pedestal leg embodying similar features.

In the structure illustrated in Figure 1' the truck frame is of a familiar type having I wheel pieces 1 connected by transoins 2 and including integral pedestal legs 3 spaced from each other a suflicient distance to acand the portion of the side walls of the pedestal between webs 5 and 6, the distance between webs 6 will be suflicient to accominodate a roller bearing journal box of greater width as indicated at 7. 8 indicates the usual wear plates which may be applied to thelegs irrespective of whether they terminate With webs 5 or webs 6.

The pads 14 to which plates 8' are bolted extend far enough away from the center line of thepedestal so that the flanges of. thewear plates will be supportedwhen the inner box-engaging elements 5 have been removed and the wear plates have been applied to the leg faces thereby formed. Thepads 14 may be originally provided with holes 15 for accommodating the wear plate in either position.

By purchasing trucks constructed as shown on the righthand side of Figure 1, therailway company can utilize the present standard journal box, but if at any time in the cornmodate a standard A. R. A. journal box Wider roller bearing box. This enables the railway company to retain the desirable onepiece truck frame and pedestal structure without scrapping the old frame. Obviously my invention is adapted for use on six wheel trucks as well as on four wheel trucks as mentioned above would be increased in and the economy of the use of my invention v and journal boxes when a six wheel truck was involved.

The same general features are included in the individualpedestal illustrated in Figure 4 which is' adapted to be bolted or riveted to the truck frame. This pedestal includes the opposed vertical transverse webs 9 adapted to engage the sides of the standard journal box and the pedestal also includes transverse webs 10 parallel with, and spaced from webs 9 and adapted to engage the sides of a wider box after webs 9 and the adjacent portion of the side walls 11 have been cut away.

In Figure 5 I illustrate an individual pedestal leg element adapted to be secured .to the truck frame and also provided with spaced transverse webs 12 and 13 adapted,

' adapted to engage the side of a standar'd journal box to position the same, and a member spaced from said surface and adapted to engage the side of a journal boxof greater width than the standard journal box when the elements forming said surface are removed. 40

3. A truck pedestal leg comprising elementsdtormmg a ournal. box engagmg surface, side-walls extending at right angles to said surface, and a transverse member between said walls and. spaced therefrom.

parallel with said surface a. ltn, a truck pedestal leg adapted to have aportion of its structure cut away to accommodate different sizes or journal boxes, a wear plate mounting pad on theside wall of the leg extending toward the rear of said leg far enough to mount thewear plate in different positions there being a plurality of holes in said pad for receiving a wear plate bolt when said plate is indifferent positions.

5. A truck pedestal having spaced legs each of said legs having a plurality of faces respectively adapted to engage the sides of journal boxes of different widths.

6. A truck pedestal with spaced legs having elements adapted to embrace the sides of a standard railway journal box and also having members spaced from said elements and adapted to embrace the sides of an antifriction bearing box when said elements are removed from said legs.

Kid

7. In a railway truck frame, an integrallyv formed wheel piece having spaced legs for receiving a standard journal box between them, said legs being of such extent longitudinally of the frame that a portion of each leg may be removed to accommodate journal boxes wider than a standard journal box.

8. In a railwaytruck frame, integral pedestals, each having integral elements adapted to embrace the sides of a standard journal box, and members in said pedestals spaced. from said elements and adapted to embrace.

a wider journal box when said elements are removed.

9. In combination, a truck pedestal leg having a plurality of elements spaced from each other so as to successively engage the respective sides of journal boxes of ,difierent widths, and a wear plate adapted to fit over either of said elements.

10. In combination, a'truck pedestal having spaced legs, each ofisaid legs having a plurality of elements respectively adapted to engage the sides of journal boxes of difierent widths, wear plates adapted to fit over said elements irrespective of the journal box assembled therewith, and means for securing said wear plates to said legs.

11. In a truclr pedestal leg,.an inner transverse web for engaging a journal box, a

second web, co-exten'sive with and spaced from said inner'web, for. engaging a journal box when said inner webis removed.

- 12. In a truck "pedestal, spaced inner webs adapted to receive an A. R; A. journal box between them, secondary webs co-extensive with and spaced from said inner web and adapted to receive a wider journal box be-' tween them when said inner webs are moved.

In testimony whereof I hereunto ai'iix my signature this 7th day of March, 1927.
