LUBRICATING SIDE BEARING FOR CARS.

SPECIFICATION forming part Letters Patent No. 767,745, dated August 16, 1904,

Application filed February 15, 1904-.- $erial No. 193,574- (No model.)

T all whom it 777M147] concern:

Be it known that I, GEORGE GALLowAY, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Lubricating Side Bearings for Cars, of which the following is a specification.

This invention relates to lubricating side bearings for railway and street cars.

Side bearings have heretofore been made in which the lower bearing member, which is secured to the truck-frame, is hollow and constitutes a lubricant-receptacle from which the lubricant is fed upwardly to the bearing-faces 5 of the upper and lower bearing members by wicking or waste confined in the receptacle and having portions exposed through holes in the top of the lower bearing member. Such constructions are objectionable principally in that the upper face of the lower bearing member is repeatedly exposed in use and permits the wicking or waste to collect dust and dirt, which cakes the exposed top portion of the wicking and prevents it from properly feed- 5 ing the lubricant to the bearing-faces.

The object of this invention is to provide a lubricating side bearing of simple and durable construction in which the bearing-faces will be kept clean and properly lubricated 3 and which will operate without replenishing for long periods, and also to so construct the bearing that in case the truck is derailed the bearing members will not interlock, thus permitting the car to be replaced without jacking up by the ordinarycar-replacing switch or track.

In the accompanying drawings, Figure 1 indicates by dotted lines one end of a car and truck provided with a side bearing, shown in Like letters of reference refer to like parts in the several figures.

' struction.

The upper bearing member B is curved horizontally concentrically with the axis about which the truck turns and is secured to the 5 car-bottom, for instance, by bolts (not shown) passing through bolt-holes C in the horizontal end flanges O of the bearing member. The latter is hollow and constitutes a receptacle or reservoir for the lubricating-oil and oily 7. waste ordinarily employed, which is shown at D. The upper bearing member is provided in its bottom with one or more (preferably two) lubricant-feed openings E, which are preferably elongated and extend transversely across the bottom of the bearing member for practically the entire width of thebearingface of the lower member, so that the lubricant is distributed over the whole of said face. The feedropenings are surrounded by upright marginal flanges e, which extend well up into the lubricant reservoir or chamber to prevent the lubricant from flowing out of the feedholes and wasting. The oily waste extends down into and through the feed-openings into 5 contact with the top face of .the lower hearing member to wipe and lubricate the same in the movements of the latter against the upper bearing member. When the hollow upper bearing member is filled with lubricant 9 and waste and secured to the bottom of the car, the lubricant-chamber is closed to confine the waste and lubricant and prevent its escape from the reservoir or chamber. The lubricant reservoir or chamber is of a size tocontain sufficient lubricant to properly lubricate the bearing for a long period of time and does not have to be removed from the car to replenish the lubricant and waste except at such times as the car in its ordinary wear and tear is returned to the shops for repairs. As the lubricant-feed openings are in the bottom of the upper bearing member,

the waste therein which feeds the lubricant to the bearing-faces cannot collect and hold dirt and dust as it does when located in holes in the top of the lower bearing member. The device therefore always properly feeds the lubricant and wipes and lubricates the bearing-face of the lower bearing member, while the wasting of the lubricant is prevented by the lower bearing member, which underlies and closes the lubricant-feed openings.

F represents afilling-opening in the side of the hollow upper bearing member, which is closed by a screw-plug or other suitable device.

The upper bearing member is provided at its opposite ends with beveled or rounded vertical webs or ribs G, which connect the bottom portion of the member with the enclsecuring flanges thereof. These webs or ribs serve to strengthen the bearing member, and in the event of the truck leaving the track, and thereby throwing the lower member out from beneath the upper bearing member, as indicated in Fig. 6, they engage the end of the lower bearing member and, owing to their beveled or rounded edges, are enabled to ride upon the lower bearing member when the truck is swung back into place on the track by the ordinary car replacing switch or track. If the upper and lower bearing members were provided with abrupt end faces, such replacing of the car would be impossible,and it would have to be jacked up to permit the upper bearing member to be returned to its place on the lower bearing member.

I claim as my invention 1. In a car side bearing the combination with a lower bearing member, of an upper bearing member movable on said lower bearing member in an arc about a center situated outside of said bearing members and having a lubricant-chamber provided in its bottom with one or more feed-openings which are closed by the lower bearing member and feed the lubricant thereto, and marginal flanges which surround said feed-openings and project up into said lubricant-chamber, substantially as set forth.

2. In a car side bearing the combination with a lower bearing member having a flat bearing-face, of an upper bearing member having a flat bearing-face movable on the flat bearing-face of the lower bearing member and havinga lubricant-chamber provided in its bottom with one or more feed-openings for the lubricant, marginal flanges which surround said feed-openings and project up into said lubricant-chamber, and a porous material in said feed-openings, substantially as set forth.

3. In a car side bearing, the combination with a lower member, of an upper member provided with a lubricant-chamber having one or more feed-openings in its bottom for the lubricant, and inclined portions at the ends of the bearing adapted when the upper member is displaced to ride upon the lower bearing member, substantially as set forth.

4. In a car side bearing, the combination with a lower member, of an upper member provided with a lubricant-chamber having one or more feed-openings in its bottom for the lubricant, horizontal securing-flanges at the ends of the bearing member, and vertical ribs connecting the bottom of the bearing member with said securing-flanges and having inclined or beveled lower edges, substantially as set forth.

Witness my hand this 12th day of February, 1904.
