To culi whom it may concern:

Be it known that I, JAMES A. ANDERSON, a

i' citizen ofthe United States, residing at New York, Manhattan borough, in the county and 5 State of New York, have invented 4certain newand useful Improvements inY Thrust-- Bearings, which improvements are'fullyset .forth in thel following specification.

This invention relates to improvements in j l bearings for shafts disposed lto sustain substruction, durable, eilicient, arid rehable; in

practical service, Which shall embody feaj 1n con'unctionywith a revolving shaft subj ect to en vpressure a film orbody of lubricant,- whereby friction resultin from. the end pres. surezon'sad shaft shall e eiectually over` come and the 'wearing effect between said shaftand the bearing reduced to a minimum,

and shall possess certain well-definedfadvanta es over prior analogous constructions."

being adapted to `carry at one end the propeller. As arranged inthe drawingsthe ro` peller is'to be secured to the-end 6 of the s aft so that thev thrust 'of the propeller or screwv will be towardtherightfhand end of the ap- 65. paratus Yas arranged inFig. 1. This shaft lwi'thi'n the bearing-casingl is provided with a series of annular thrusterings -7, which areannular channels 8. These thrust-rings are preferabl formed integral with the shaft; ut it wi lof course be understood that they maybe secured-thereto in anysuitable manner. These yrings are 'so arran ed o n the shaft that they rotate within the ubricant or oil compartment 2, as shown clearly in Fig. 1, and are of such diameter that their lower portions extend below the level of the oil in l said compartment. Fitting closely within the channels 8 are okes9, whose ends are bolted .o

To this endthe piston in the steamcylinder is of much greater area than the piston in theoil-cham er, so thatthe pressure of th'el oil in the oil-chamber willbe consider- .ably greater than-'the steam-pressuref-on'- the piston 30. By this means a supplyofwoil is maintained under `a heavy pressureincommunication with theinletf-ports 43 of the casings 19.` Should the pressure maintained by the pump be decreasedfor instance, 4b reason of reduction in'steamressure--t e. olil-` in the oil-chamber 29 wo'ul be forced down-y ward 'by the steam above the piston -30:,to

. compensate for `the reduction in pressure maintained 'by the pump. The downward movement of the steam-piston would rock shaft 37 and open valve 41 through its con- v nections 38 and 39, increasin thegsupply of steam to the pum and there y accelerating its movement an .permitting it to raise the y oilressure.
