SIDE BEARING FOR RAILWAY-CARS.
6 of Illinois, hav'einvented a certainnew and useful Im rovementl in Side Bearings .for VRailvrayars. of vwhich the following is a full,` blear (oncisc, and exact description. lerelice lng had tothe arcompanyingr ld'rawlniezis,'forming a part of this specificainvention relates to improvementsin side bearings for railway cars.
The object of my invention is to provide aiiple eiiicien't liiterallv and vertically adjustable roller side bearing.
' In the drawing forming a part of this specification, Figure 1 is a vertical section of a side bearing embodying` my invention. Fig. 2 is a se;tional view of the roller emplo therein.
ferring to thc drawings, the numeral 10 indicates a bolster shown in cross section, to which the bearing is secured. It .will be understood that in a railwa car an opposed bolster is employed which the roller, hereinafter described, is designed to be engaged by. The numeral 11 indicates a base member having suitable means, as for instance, the llanges 12 adapted to be employed in secur-l ing the bearingr to the bolster by suitable means, as for instance, the rivets 13-13. A roller 14 is mounted between the up-standin sides 15-15 ofthebase member, the said 1'0 ler being provided with an axle 16 upon which it is adapted to revolve.
The axle 16 comprises the central spherical portion 1T andthe trunnions 18 extended from either e' d thereof, the said spherical portion 16 being hollow to receive the waste and oil, indicated at 19, and provided with suitable perforations, such asindicated at 20,to lubricate the bearing;r of the roller upon the s herieal portion of the axle.` The upstan in sides 15 of the base member 11 are provide with suitable slots 21 to receive the trunnions of the axle, the lower portions of the slots 21 beine' provided with shoulders 22 upon which the lower portion of the trunnions, indicated at 23, are adapted to rest. Filler pieces or .shims 24 are rovided of such suitable number or dimensions as may be desired, in order to rmit the vertical adjustment of ".1 roller 1n the base member 5,8. to' accommodaI Varying spaces between the Specification of Letters Patent.

holsters upon cars to which the bearing is applied. Suitable means are provided, as for instance, the keys 25 to retain the axle in its position within the base member.
The roller 14 is provided with thc longitudinal perforation 26 in which the axle is received, the said perforation 26 having a spherical conformation intermediate its ends, as indicated at 27. to form the bearing face which rides` upon the spherical portion 16 0f the axle.l Near its ends, as indicated by t-lie numeral 28, the said perforation is of suitable dimensions to permit the lateral oscillation of the roller 14 upon the axle in order to accommodate the roller to de ections of the holsters between wvhich the roller is mounted.
It will be observed that the spherical p01'- tion of the axleI is of a larger diameter than the ends of the perforation 26 extending through theroller. The roller. as shown in the drawings, is made in one piece.
I will now describe the method of placing .f
such `an axle within a roller having an opening so conformed. The roller is cast in the form hereinbefore described, whereupon the walls of the perforation 2G are lined with plnmbago or the like. a suitable mold is formed and a core to provide the openings in the axle, whereupon molten metal is poured within the mold and the axle thus is cast within the roller. the plumbago or other like substance preventing the destruction of or injury to the roller, and reventing the union of the metal 4of which the axle is By this method a very simple and eliicient side bearingr can be made and one in which both lateral oscillation pr adjustment of the roller is provided for as well as vertical adjustment, all to meetl varying conditions in car structures and in service conditions thereon.
I claim:
1. ln a side bearing for railway cars, the com ination with a retaining member, of a one-piece roller and an axle therefor, the roller having a curved inner bearing face to engage the axle and the axle having similai-ly curved bearing faces, the axle being removable from the roller only through destructive edoirt.
2. In a side hearing for railway cars, in
piece rollerY associated therewith; an axle upon which the. roller is mounted; the roller combination: a retaining4 member; a onebein provided with a perforation, the said per eration being formed intermediate its ends by a curved bearing face upon the roller, the axle being provided with a spherical bearing member upon which the roller may oscillate laterally.
3. In a side bearing for railway oars, an axle having a sphericalabearing portion, a one-piece roller partially surrounding said spherical bearing portion, and a retaining member; the axle being provided with trunnions extended from its spherical ortion, said trunnions being supported in the base member.
4. In a Side bearing for railway cars; an axle having a spherical bearing portion; a one-piece roller partially surrounding said spherical bearing portion; and a retaining member; the axle being provided with trun` nons extended from its spherical portion, said trunnions being supported in the base member and having vertical adjustment therein.
5. In a side bearing for railway cars; a retainin member; a roller therefor and an axle gir mounting the roller in the base member; the roller having an axial perforation to receive the axle, the axle having a larger diameter than the ends of said erforation and being east in said perforation.
6. In a side bearing for railway cars, in combination: a retaining member; an axle mounted therein; a roller upon said axle and having lateral oscillating movement thereon; the roller having an axial perforation, the axle having a central spherical bearing portion of larger diameter than the ends of said perforation and being cast within said perforation.
7. In a side bear"ig for railway. cars: a
base member; a roller assoclated therewith; a spherical bearing member within the roller partially surrounded thereby; and trunnions extended from said spherlcal bearin member to engage the base member, t e Said spherical bearing member being cast within the roller.
In witness that I claim the fore oing I have hereunto subscribed my name tlis 19th day of May, 1917.
