Be it known thatl I, Gaone iUsUs'ry RU- noLF llHNn, citizen of Germany, residing'at Hamburg, Germany, have invented certain 5 new andnseiul` Improvements 1n Liners, Bushes, and the like, for'Bearings and lPed- 'estals (lor"which` I havei'liled an.A application in Germany on November 25, 1921),"of which the following is a specification;
It has been proposed'to construct. bearing shells or bearingboXes for shafts, spindles` and the like of lumps ot hard material embedded in va layer ot' soft metal', thus filling thev intervals between they said lumps et hard material. -When constructing bearing b oXesin V this ymanner .it` was thel idea to use particularly hard stonesl such as `flint in the sott metal or other suitable composition, However in practice ithas been found that it is advisable Vto use not too hard f stones. In fact trials have proved that the most suitable degree of hardnessfor the present purpose is between three and tour.v
Particularly lime stone, shell stone and the like belonging to the grou l of calcareous spar have proved to be or extraordinary value. this purpose as long as it has the desirable degree of hardness.
which hardens or sets to lthe desired degree. Thus it has been proved that carbon such as is used for electric purposes for inst-an'e for electric lamps or for collectors and the like has given very good results.
It has also been found that bearing boxes of the description mentioned above now and then hadgthe drawback that the lubricant finds its way out attheend of the bearing through the shell or liner. this is .that minute cavities are created in pouring in the liquid'mass, which cavities frequently combine to channels leading up to the very basis of the shell or liner.
present .invention mountings or settings are provided on the rear, side ot the stones cona pedestalA is Also artiiicial stone can be used for By the term artificialstone I intend V.to apply all stony material The cause of Tov avoid these inconveniences according to the .an alloy with the whitemetal.

If gutters as described are used theV mounting of the bearing'bon is very much facilitated'. f
The stones may be given a yregular shape if desired for instance such as that of balls or cylinders as is shown in Fig. 3. VThe gutter-like mounting bis then also formed to well suitthe cylindrical shape of the stones. ln Figs. and la the stones have the shape of a trapezium. in which case also h -3.iring',A phey are rst filled with the stones and -tlien placed` upright in the hearing box about a mandrel or core and then the liquid material such as `white metal is poured in. This metal combines with the bent metal strips to form a unitary or compound `body particularly when the metal strips are made ot tinnediron, the tin of which terms lt will be evident that, even if cavities or lnterstices happenl to be pllt, there isv more Y Fig. 5b anend viewof'the mountings When stones.
