APPARATUS FOR JOURNALING RAILWAY VEHICLE AXLES Filed July 14. 1928 3 SheefcsSheet 3 l v /E/v TO B HARRY/W PLAER Patented June 24, 1930 UNITED STATES PATENT OFFICE HARRY M. PFLAGER, OF ST. LOUIS, MISSOURI, ASSIGN'OR, BY MESNE ASSIGNMENTS,
TO GENERAL STEEL CASTINGS CORPORATION, OF GRANITE PORATION OF DELAWARE CITY, IIELINOIS, A COR- APPARATUS FOR JOURNALING RAILWAY VEHICLE AXLES Application filed July 14, 1928. Serial No. 292,683.
quired by a friction bearing box for the same sized journal. Obviously, the wider the box, the wider the pedestal opening must be to accommodate the box, and, the higher the box above the'journal, the higher the equalizer end must be extended. Hence, ordinarily, the same pedestal will not accommodate both types of boxes for the same journal. In Patent No. 1,664,830 and 1,664,831,
issued to me April 3, 1928, I illustrate pedestal structures which are adapted to accommodate an A. R. A. standard friction bearing box or a wider anti-friction bearing box.
The object of my present invention is to provide a pedestal and box structure in which the pedestal will not have to be changed, but in which the change from a friction bearing to an anti-friction bearing can be made b changing the box only, or vice versa.
In the accompanying drawings which illustrate my invention- Figure 1 is a fragmentary side elevation of a six wheel truck showing the application to one of the pedestals of an anti-friction bearing box and showing the application to the other pedestal of a friction bearing box for the same sized journal. In this figure the friction box 'is sectioned for purposes of clearer illustration.
Figure 2 is a transverse section through one halfof the right hand box shown in Figure 1 and is taken substantially on the line 2-2 of Figure 1.
Figure 3 is in part a top View and in part a horizontal section taken on the line 33 of Figure 2.
Figure 4 is in part a section and in part a front elevation of a modified friction bearing box which may be substituted for the box shown in Figures 2 and 3.
horizontal section taken on the line 6-6 of Figure 5.
Figure 7 is a longitudinal section through a roller bearing box utilizing different type of roller bearings which do not necessarily require a box of greater width than the A. R; A. standard friction box for the same size of journal.
Figure 8 is a transverse section taken on the line 88 of Figure 7 In Figure 1 I illustrate a truck having a frame including a wheel piece 1 with integral pedestal legs 2 which receive between them the journal boxes 3 and 4 which boxes support the equalizers 5 which mount springs 6 on which the wheel piece 1 is supported. The truck frame structure and equalizers resemble those now in general use and, in themselves, do not comprise my present invention.
The legs of each pedestal are spaced apart tal legs of approximately nine inches, while a corresponding anti-friction box usually requires a pedestal leg spacing of approximately fifteen inches, and it will be understood that this latter spacing of the pedestal legs is indicated in Figure 1 of the drawings. The box 4 comprises a main portionhaving side walls 7, a bottom wall 8, and a top wall 9, which are arranged and spaced from each other substantially the same as a standard A. R. A. friction bearing box, the box including lugs 13 for the bearing wedge.
Spaced from each side of wall 7 of the box is a pedestal engaging wall 10, parallel with the side wall"? and connected therewith by transversely extending ribs 11 which project beyond wall 10 to engage the inner and outer faces of the pedestal leg to guide the box in its vertical movement. Preferably, suitable reenforcing elements 12 connect the box side walland the parallel wall 10.
Spaced above the top wall 9 of the box is a bearing member 14 upon which the equalizer 5 may rest in the same manner as it would rest upon an anti-friction bearing box, in which the distance from the center line of the axle to the bottom of the end of the equalizer is greater than in standard friction bearing boxes.
The ribs 15 at front and back of the member 14 support the same from the box top and form guiding lips 16 for the equalizer. The remainder of the box structure corresponds to a standard A. R. A. friction bearing box, and it will be noted that such a box not only is adapted to receive a standard lid dust guard, friction bearing and wedge, but does not require any increased amount of waste or oil. At the same time, the box, as illustrated, will fit into a pedestal designed to receive a wide anti-friction bearing box and this construction will enable a railroad to purchase trucks that are adapted to mount anti-friction bearing boxes and axles without requiring the road to equip its trucks with such boxes and axle journals at the time the trucks are built, and without requiring any work on the truck frame or truck pedestals when a changeis to be made. All that will then be necessary will be to remove the friction bearing box and axle just described and substitute an anti-frictionbearing box and axle. lVith many installations the old axle may be retained and machined so as to mount the anti-friction bearing.
At the same time, the box described is adapted to have the outer walls 10 and the extended portions of ribs 11 removed, together with elements 12 and member 14: and the upper portions of ribs 15, whereupon the box may be mounted in a pedestal in which the jaws are only spaced nine inches apart and in which the equalizers are supported closer to the center of the axle than in an anti-friction box. In this way, a box may be used in pedestals and trucks which were made to accommodate standard A. R. A. boxes only.
In Figures 4, 5 and 6, I illustrate a modified form of box adapted to accommodate a standard friction bearing and wedge but having a single pair of side walls 17 adapted to engage the pedestal legs and provided with guiding flanges 18. In this box, the wedge lugs 19 are spaced from the box side walls 17 and are braced by suitable ribs 20. The other features of the box are substantially like those of the box detailed in Figures 2 and 3 and this box enables the road to use standard friction bearings and equalizer structure, carried on a journal mounted in a pedestal designed for a wide anti-friction box. Thisbox would require a larger amount of packing material and more lubricant and would not be adapted for application to the pedestal with the legs spaced apart to accommodate a standard friction box.
In the modification illustrated in Figures 7 and 8, I show a roller bearing box of a spaced pedestal legs and also has inner side walls 22 adapted to engage pedestal legs which are arranged for receiving an A. R. A. standard friction bearing box. It will be understood that before the box illustrated can be used in the narrower pedestal, the outer walls 21, together with the outer portions of the flanges 22 and the elevated equalizer seat 23, would have to be removed.
In each form of my box structure, I have shown a box adapted to fit into a pedestal having widely spaced legs, and, at the same time, provide a mounting for a journal bearing w ich heretofore could only be used in a box mounted in a pedestal having leg relatively close to each other.
While I have illustrated a truck frame with integral pedestal legs, it will be underwithout departing from the spirit of my invention, and I contemplate the exclusive use of such modifications as come within the scope of my claims.
