These oil Wells, which are external, here frequently become broken ofi when the apparatus is in use. Furthermore., 'the oil reservoir 13 is better adapted to contain a ll suppiy ot oil so that the times of refilling need not be very frequent.

It is understood that my invention may be modified in arioue Ways as will occur to those skilled in the art and what l2 said machine, said plate having therein an integral oil reservoir, a bearing carried by the plate adapted to receive a Shaft, Said bearing and end plate having an opening extending Sinto the reservoir and a wick eX- tending from the reservoir through the open'- ing and carrying the oil to the shaft, and means mounted in the reservoir for support'- ing and guiding said Wick.

2. An end bearing for a shaft of an elec tric machine, comprieing an end plate for saidv machine, an integrally cast oil raser" voir in said end plate, a bearing carried by said plate and adapted to receive a shaft, a Wick projecting through the bearing cnntacting With the shaft and extending into the reservoir, annular oil catching depreff: sions in said plate about the Shaft at the ends of the bearings and oil ducts leading back from said depressions to the reservoir to return excess oil thereto, and means mounted in the reservoir for euliporting and guiding said wick.

An end bearing for dynamo eiectric machines, comprising an end plate 'for :said machine, an integmllyv cast oil reeervoir therein, a bearing carried by Said plate, a shaft extending therethrough, annular depressions in said shaft adjacent the end of the bearing, annular depressions in said plate adjacent the end of the bearing, a felt ring carried by the Shaft adapted to collect excess oil therefrom and deposit the oil in the depressions in the plate and drain back ducts leading from Said depressions to the oil reservoir 'to return the oil thereto, and means mounted in the reservoir for anp porting and guiding said Wick.

4l. An end bearing for a dynamo electric machine, comprising an end plate therefor, laaid plato havingr an oil reservoir integral tlieiefu'itlny a bearing carried hv the earl plate, and having an openingr for an oiling` wirk, a wick retaining tubo threaded into the reservoir and projecting upwardly toward the bearing, a wick in Said tube and a spring 1n Haiti tubo abutting against the cloeod lower end thereof and against the wirk for urging' the wiel: againet the Shaft rotating in the bearing.

5. An. end bearing tor an ciectric machine,

ineide of the tube from the reservoir, a en n aid'tnbe rating against the closed thereof and a wick in said tube urged egainstthe shaft in the. bearing by said sprinu.

6. n end bearing for a dynamo electric machine, comprising an end plate therefor, Said end plate having an oil reservoir integzta` ierewith, a bearing carried by the end plates and'having an .opening for an oiling Wick, a w' :k retaining tube threaded into the reservoir and extending upwardly tov-Jamil the bearing, a wick in Said tube, a Spring in said t be abutting against the closed lower end .thereof and against the wier: to urge the wick against -a shaft ro- 'Eating in the bearing, annular depressions in said end plate adiacent the ends of the said bearings and return ducts leading from said deiref-ieiona tcthe oil reservoir, said return direte being adapted to carry back any excess oil caught in said depression.

7. ln a device oir' the character described, the conibiiiati with a bearing; of an oil reeervoir thereror; e Wick extending from the reservoir and through the bearing; and wick guiding means removably mounted nuthin the reservoir.

8. In a device of the character described, the combination with a bearing; of an oil reaervoir therefor; a. wick extending from the reservoir and through the bearing; and a wick guiding and supporting member detachabli," mounted .Within the reservoir.

9. In a device of the character described, the combination with a bearing; of an oil reservoir therefor; a Wick extending from the reservoir and tlnough the bearing; a wick guiding and supporting member screwthreaded into the bottom Wall of the reservoir and having a hole therethrough located above the bottoni of the reservoir; and a Spring located in Said wick guide for maintaining said Wick above the bottom of the reservoir and for yicldingly maintaining tlie iviclr against a shaft in said bearing.

10. In device ot the character described, the combination with a bearing; of an oil reservoir therefor; anvic.; 'extending from the reservoir and through the bearing; and a drain plug for the reservoir conetructcd l arranged to Support and guide the ujiclr.

il. ln a device o'l the character doecrihed, the combination with a bearing; of an oil reservoir therefor; a Wick extending from the reservoir and through the bearing; Wick guiding means removably mounted within the reservoir; and means carried by the guide for yieldingly urging the Wick toward the bearinff.

12. n a device of the character described, the combination with a bea-ring; of en oil reservoir therefor; a Wick extending from "signature the reservoir and through the bearing; e tubular Wick guide removably mounted within the reservoir and adapted to receive the wick; and a coil spring mounted Within the Wick guide for ggf'iedingly urging the wick toward the bearing.
