430,191. Bearings ; lubricating. WARLOP, P., 5, Avenue de Bobigny, Noisyle-Sec., Seine, France. Feb. 21, 1934, No. 5716. Convention date, Feb. 21, 1933. [Classes 12 (i) and 12 (ii)] A loose bearing liner in the form of a sleeve 1 has, for facilitating film lubrication, one or more circular grooves 2 and radial holes 3, 4, 5, in each groove. The holes in the various grooves may be in staggered formation, and longitudinal or helical grooves 7 may connect the holes in different grooves. The axial spacing of the holes is preferably such that any transverse plane intersects the holes of at least one groove. The bearing and liner may be in halves. The Specification as open to inspection under Sect. 91, comprises also a bearing in which a lubricant outlet 4, Fig. 3 (Cancelled), is formed near the point G of minimum film thickness. The outlet 4 may be connected by a channel 2 to a point 3 where the oil pressure is lower so that oil circulates in the direction of the arrow f<12>. The channel 2 and the points 3, 4, may be duplicated on the other side of the bearing. In a modification, a bearing liner is built up of intermediate rings 12, 1<3>, Figs. 11 (Cancelled) and 12 (Cancelled), and end rings 11, 1". The intermediate rings 1<2>, 1<3>, have on each side a shoulder 41<1> and apertures 3, 4, 5, 31, 41, 51. Notches 7 connect these grooves to the opposite side of the central rib of each ring. The end rings 11, 1", which have only one shoulder 411, have axial channels 17. A modified method of building up the rings is also described. The bearings described may have additional oil channels 25, Fig. 15 (Cancelled). In another construction, a liner has slots 3, 4, Fig. 16 (Cancelled), and flanged ends 16 through which oil ducts 171 pass to the end thrust faces. In another construction, a loose thrust ring 20, Figs. 18 (Cancelled) and 20 (Cancelled), has ducts 3, 4, which open at one end to recesses 25, and are connected at the other end by recesses 2. This subject-matter does not appear in the Specification as accepted.
