CAB PLATFORM.
Application filed July 25, 1925. Serial 110. 46,158.
My invention relates to railway rolling stock and consists in an improved construction of the frames of car platforms and the like.
The object of my invention is to provide in such a platform -a side bearing arch adapted for the application of anti-friction side bearings at a higher level than has been possible with side bearing arches used herethe truck bolster beneath the side bearing arch for the application of side bearings, particularly side bearings of an anti-friction type. This condition exists in six, wheel trucks in which the side bearings are usually locatliied above the middle wheels of the true I accommodate this condition by so shapin the side bearing arch that it may have a si e bearing applied thereto with a substantialportion of the side bearing located above the bottom of the arch. I also so shape the side bearing receiving portion of the arch so that the side bearing may be visible from the side of the car, thereby facilitating inspection of the side bearing. Inthe accompanying drawings which illustrate a selected embodiment of my invention- Figure 1 is a top view of a car platform having my improved side bearing arch.
Figure 2 is a a transverse vertical section on line 2-2 of Figure 1 and showing an anti-friction side bearing in position and also showing the adjacent portions of the car truck.
Figure 3 is a side elevation of a portion of the side bearing arch with a side bearing applied and indicatin the adjacent wheel.
. The platform 'inc udes the usual draft sills 1, end sill 2, side sills 3, transoms 4, and center sill connection 5. Connecting tran soms 4 on each side of the center line of the car is a longitudinal side bearing arch member 6, the end portions of which are I- shaped in cross section and in the intermediate portion of which, the web 7 of the I-shaped section is offset, as indicated at 8. The lower flange 9 on one side of the web is also ofi'set as indicated at 10 and the lower flange 11 on the other side of the web is cut away abreast of the oflset portion of the web. The. upper'flange of the arch is disposed the same throughout its length.
The offsetting of the member intermediate its ends as described above provides a Z- section with closed ends forming a housing for receiving a side bearing S which may be secured to the underside of the top flange of the arch member by bolts or rivets in the usual manner.
Preferably, all of the platform parts are formed from a one-piece casting and the draft sills, end sills, transoms, and side bearing arch are in substantially the same horizontal plane. By means of my arran ement of the side bearing arch, it is possible to mount the side bearing in substantially the same plane without materially decreasing the cross sectional area of the arch member or unfavorably reducing its strength for the vertical loads applied thereto.
In Figure 2 I illustrate the middle wheel 12 of a six wheel truck, the truck frame being indicated at 13 and the truck bolster at 14,- the latter having integral upwardly and outwardly extending side bearings 15 adapted to cooperate with the body side bearing. It will be obvious from Figure 2 that the outwardly and downwardly opening side bearing housing renders the side bearing visible from the side of the car sothat the understood that other side bearings may be applied and the contour of the arch at the pomt of application of the side bearing may be modified accordingly. 7
Obviously, the integral structure of allthe platform parts shown and described b 'me i is not essential to the embodiment o my invention, and I contemplate the exclusive use of the arch described whether embodied in the integral structure or in a built-up structure.- I contemplate suchv other modi-v fications of my invention as may be included in the scope'of my claims.
I claim:
1. In a car platform, transverse transoms spaced from each other, a longitudinal side bearing arch extending between said transoms, there being a side bearing housing formed in said arch above the bottom thereof and opening downwardly.
2. In a car platform, a side bearing arch,
and a side bearing housing formed in" said arch above the bottom thereof and opening outwardly to permit inspection of the side hearing from the side of the car. J 3. In a car platform, transverse transoms spaced from each other, a side bearin arch extending between said transoms an comprising a vertical web and an upper horizontal flange adapted to mount a side bearing which may be applied to the arch or removed therefrom in a substantially horizontal direction.
4. In a car platform, transoms, a side bearing arch between said transoms, all of substantial depth throughout their lengths for sustaining loads applied thereto, and a side bearing housing formed in said arch above the bottom thereof and opening downwardly and outwardl 5. In combination, a six wheel car truck including a bolster with a side bearing located over one of the middle truck wheels, a
car platform mounted on said truck and including transverse transoms spaced longitudinally of the truck from the center line of the center axle, said platform including a longitudinally extending side bearing arch connecting said transoms and substantially level with the body of the platform, and an anti-friction bearing carried by said arch at substantially the same level as the body of said platform and removable therefrom without disassembly of said truck and platform.
6. In a car platform, a side bearing arch I-shaped in cross section atits ends and having a portion of its web and one lower flange offset intermediate its ends and having its other lower flange cut away abreast of said ofi'set portion.
7. In a car platform, transoms, and a transom connecting arch of I-shaped-section at its ends and of Z-shaped section intermediate its ends.
8. A one-piece casting comprising a car platform having transoms, and a transom connecting member of I-shaped section at its ends and of Z-shaped section intermediate its ends.
In testimony whereof I hereunto aflix my signature this 21st day 01 July, 1925.
