PATENT- OTTO W. SOHAUM, OF PHILADELPHIA, PENNSYLVANIA.
SELFf-OILING BEARING.
SPECIFICATION forming part of Letters Patent No. 712,( 502, dated November 4, 1902.
Application filed April 30, 10;!02.
To cir/ZZ whom it rita/y concern:V
Beit known that I, Grrro W. SCHAUM, a cnizen of the United States of America, aud-a resident of the city and ,county of Philadelphia, State of Pennsylvania, have invented certain new and usefullmprovements in Self- Oiling Bearings, of which the following is a specification.
My invention relates more particularly to self-oiling bearings for the shafts of centrifugal machines or the like; and it consists in certain improvements which are kfully described in connection with'the accompanying drawing, and particularly `poi'ntedout in-Ythe claims. i
The drawing shows a sectional `elevationof a preferred construction embodying my invention as adapted to the shaft of a centrifugal hydroeXtractor. i
A represents the lower portion of the rotary shaft; B, the journal-bearing therefor, and O the bearing-casing,whi'ch is rigidly secured to the frameQ of the machine. The journal-bearing B is Xed centrally :in the casing C, which forms about it an annular chamber 1 with a communicating extension 2 above the bearing B and another extension 3 below said bearing, said chambers forming an oil-reservoir of any desired capacity and form. i
-To provide a step-bearing for the shaft A, a central step-bearing boss 4 rises above the bottom of the reservoir chamber 3 and is preferably formed with a recessed seat 5 for a separately-formed step-bearing plate 6, of hardened steel, upon which the end 7 of the shaft A bears. This step-bearing plate Gis centrally perforated at 8 to communicate with au oil way or conduit 9, formed in the boss 4 and opening upward through said boss to one side of the shaft-bearing, thus forming an approximately U -shaped oil-conduit, the purpose of which conduit is to supply oil to the step-bearing as well as to the j ournal-bearing, as hereinafter described, from a point in the reservoir above the bottom of the latter, thus utilizing the annular portion of said reservoir below the level l0 of the boss 4 as a settling-chamber. y
To provide for the automatic circulation of oil-through the bearing B during the rotation of the shaft, I form one of said parts, prefer- Serial No. 105,276. (No model.)
ably the bearing, with a spiral passage-way 11, winding upward about the shaft in the direction of rotation, through which passageway the oil is elevated to the upper chamber 2 of the reservoir, the normal level in the latter being maintained by its communication through openings 12 12 with the lower portion of the same. Within the oil-reservoir I provide also an 'exit or overflow conduit 13, the mouth14 of which is at a point iu said reservoir below the level 10 of the stepbearing boss 4, so that it communicates directly with the lowerrnost portion of said reservoir. This conduitrises to about the level of'the top of bearing B, where it has a conveniently-located side outlet 15. The purpose and effect of this conduit is to limit the `height of oil in the reservoir by automat- .reeel-voir, a rotatable shaft in said bearing and a conduit in which the oil ows upward, in contact with the shaft and bearing, from the portion of said reservoir above said settling-chamber to the portioii of the reservoir above the bearing. t
2. The combination with a rotatable shaft and bearing, one of said parts having a spiral oil-conduit, of a fixed oil-reservoir extending above said bearing'and provided with a settling-chamber below the plane of the lower end of the bearing, and a step-bearing extending approximately to the plane of the top of said settling-chamber and located within the same, said step-bearing having an oil-conduit communicating with said reservoir at approximately the plane of the top of said settlingchamber. Y
3.' The combination with a rotatable shaft and bearing one of said parts having a spiral oil-conduit, of a xed oil-reservoir extending above and below said bearing and provided IOO with an elevated step-bearing having an oilconduit therein communicating with said reservoir above the bottom of the latter and an overflow-conduit communicating with said reservoir below the mouth of said step-bearing conduit.
4. The combination with a rotatable shaft and bearing, one of said parts having a spiral oil-conduit, of a xed oil-1 eservoir extending above said bearing and provided with a settling-chamber below the plane of the lower end of said bearing, and a step-bearing extending approximately to the plane ot' the top of said eenling-chamber and located within the same, said step-bearing having a periorated bearing-plate seated therein, and an oil-conduit which extends downward through the same and upward approximately to the plane of the top of said settling-chamber.
5. The combination with a rotatable shaft ot' a spirally-grooved bearing therefor, an oilreservoir extending above and below said bearing, a step-bearing in said reservoir elevated above the bottom thereof and provided with a U-shaped oil-conduit, and an overflowconduit communicating with the reservoir below said elevated step-bearing.
6. The combination with a rotatable shaft and bearing, one of said parts having an oilconduit, ot' a xed oil-reservoir extending above and below said bearing, and an overflow-conduit communicating with the lower portion of said reservoir and extending upward therefrom approximately to the plane of the upper portion thereof and having a lateral outlet therefrom.
7. The combination with a rotatable shaft and bearing, one of said parts having an oilconduit, of a 'fixed oil-reservoir extending above said bearing and provided with a setcling-chamber below the plane of the lower end of said bearing, a step-bearing extending approximately to the plane of the top of said settling-chamberand located within the same, said step-bearing having an oil-conduit communicating with said reservoir at approximately the plane of the top of said settlingchamber, and an overflow-conduit communieating with said settling-chamber and extending upward therefrom approximately to the plane of the upper end of the reservoir and having a lateral discharge-opening at its upper end.
8. The combination with a rotatable shaft and bearing, one of said parts having an oilconduit, of a xed oil-reservoir extending above said bearing and provided with a settling-chamber at its lower end, a step-bearing in said settling-chamber, said step-bearing having an approximately U-shaped oil-conduit the mouth of which communicates with said reservoir at approximately the plane of the top of said settling-chamber, and an overflow-conduit having its `mouth in communication with said settling-chamber, said conduit extending upward approximately to the plane of the upper end of the reservoir and having a lateral outlet at its upper end.
