snaar-BEARING.

To all fio/10m t may concern:

Be it known that I, JESSE M. GARBER, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful Shaft-Bearing, of which the following is a specification.

The object of my invention is to produce an automatically lubricating journal bearlng.' v

' The accompanying drawings illustrate my inventio-n.

Figure 1 is an axial section of the bearing structure complete; Fig. 2 a plan of the lower section; Fig. 3 a section on line 3-3 of Fig. 1; Fig. 4 a sect-ion on line 4-4 of Fig. 1; Fig. 5 a perspective detail of the oil deflector, and Fig. 6 a fragmentary detail of the means for closing one end of the structure,

In the drawings, 10 and 11 indicate two mating bearing members or bodies. The member 10 is provided with a semi-cylindrical seat 12 beneath which is formed an oil reservoir 13. At each end, the body 10 is provided with a semi-annular groove 14 which perforates the seat12 so as to give access to the oil chamber 13 and, at thevmiddle of the body the seat 12 is perforated by a slot 15 which also gives access to the oil chamber 13. Mounted in each end of the seat 12 is a semi-annular bearing bushing 16 which, at its inner end, is formed with a flange 17 which holds it against axial displacement in one direction. The two bearing bushings 16 are alined and are adapted to receive properly formed portions of shaft 18. Secured to shaft 18 is a circumferential rib or flange 19 which lies between the separated adjacent ends of the bushings 16 and is of sufficient diameter to project well into the oil chamber 13. Each bushing 16 at one edge is cut away, as indicated at 21, opposite a wick seat 22 formed in body 10 and extending longitudinally of the seat 12. The wick seat 22, at each of its ends, communicates with a vertical passage 23 which extends down through the body of the member 10 and communicates with the oil reservoir 13. Mounted in each wick seat 22 is a wick 24 the ends of said wick being carried down through the passages 23 and projected well into the oil reservoir 13, as clearly indicated, the wick having suflicient diameter to rub against the shaft 18.

The member 11 is provided with a semicylindrical seat 31 which mates with seat 12 and the middle of said seat is provided with .a semi-annular groove o-r recess 15 which mates with the groove 15 of member 10. Mounted in the ends of seat 31 are semiannular bearing bushings 16 which mate .with the bushings 16 and are similarly provided with inner flanges 1T. Formed through the upper side of member 11 and extending for a considerable portion of the axial length of said member, is a slot or inspection opening 32 which may be covered by a readily removable cover 33. Formed through each bushing 16', at its upper side immediately beneath the opening`32, is a slo-t 34 which extends through flange 17 and, at its end farthest from the fiange is widened, as indicated in Fig. 1, Vso as to expose shaft 18 immediately beneath the open ing 32. Mounted loosely within the opening 32 is an oil-deflecting saddle 35 which, at one side', is provided with a depending flange 36 having a middle notch 37 which is formed tofit freely but closely over the flange 19 of shaft 18. The upper or mainV plate of the saddle 35 is substantially horizontal and, at its edgeflrst passed by points on the shaft, is provided with a pair of depending, diverging deflecting wings 38, 38 flanking the flange 19. Atits outer ends the saddle 35 is provided with depending guard ends 39, 39 and, at the lower corner of the junction of each of these ends with the flanges 36, the parts are cut out to form a notch or oil passage 41. If shaft 18 is not to extend entirely through the bearing structure above described, a circular plate 42 may be provided, as illustrated in Fig. 6, to close one end of the structure.

The operation is as follows: Rotation of shaft 19 in the direction indicated by the arrow in Fig. 3 carries the oil in kchamber 13 up upon flange 19 and, when the oil reaches flange 36 of the saddle 35, said fiange scrapes the surplus from flange 19. The oil strikes the flange 36 with considerable force and tends to bank up into the corner between the upper plate of the saddle and the flange 36. The divergent wings 38, which stop short of the ends 39, guide this oil through the passages 41 into the opening 32 4and slots 34, which form the sides of an oil reservoir of considerable size, the bottom of which reser- Voir is formed by the shaft itself. From this reservoir, the oil passes down with the shaft bet-Ween the shaft and the bearing bushing 1G. Surplus of oil, when it reaches the wiel; seat 22, will flow axially of the shaft and down through the groove 14; into the oil reservoir. If on the other hand, the oil within the reservoir should fall below flange 19, the .wicks 23 will serve to draw the oil upwardly and deliver the same to the shaft. The flange or oil guard 45 on the shaft opposite the groove la at the end of the journal bearing from which the shaft projects, prevents the oil from creeping along the shaft, by throwing it by centrifugal force through such groove back into the oil chamber 13.

l claim as my invention:

l. A bearing structure comprising a pair of mating' members forming a shaft seat therebetween, the lower member having an oil reservoir formed therein with an interw mediate communication between theshaft seat and the oil reservoir and the upper member having a longitudinal pocket com munieating with the shaft seat; a shaft mounted in the shaft seat and carrying a ciroumferential flange projecting into the oil reservoir and the pocket, and an oil-deflecting saddle mounted in the pocket of the upper member and closely straddling the shaft flange in such manner as to receive oil therefrom, said saddle comprising a portion overlying the shaft flange and provided with depending oil defleetors and with a. flange depending toward the shaft for removing oil from the flange on the shaft after such oil has been carried by the rotation of the shaft past such oil deflectors,

such depending flange being separated from the oil deflectors in the direction of rotation of the shaft.

2. A bearing structure comprising a lower member having a pair of axially separated bushing seats and an oil reservoir Communicating with the space between said bushing seats, a pair of axially separated bushings mounted in said bushing seats, a mating upper member having a pair of axially separated bushing seats and an oil pocket formed in its upper side, a pair of axially separatedbushings mounted in said last mentioned bushing seats and each having an opening through its upper side opposite the oil pocket, a shaft journaled in said bushings and carrying a circumferential flange lying between the axially separated bushings of both pairs and extending into the oil reservoir and the oil pocket, and an oil-defiecting saddle loosely mounted within the oil pocket and comprising a portion which over-lies the shaft flange and is provided with a depending notched flange closely straddling' the shaft flange and with depending oil-defieeting flanges, said oil defleet-ing flanges being spaced from said notched flange in a direction opposite to the direction of rotation of the shaft.

In witness whereof, I have hereunto set my hand and seal at Indianapolis, Indiana, this 17 th day of March, A. D. one thousand nine hundred and eleven.
