Abstract: 100,448. Pressed Bearing Co., (Assignees of Klockc, W.). May 8, 1915, [Convention date]. Bearings.-Lined bearing-brasses are produced by coating or lining a backing-metal, such as brass, with a metal such as Babbitt-metal, and bending to shape in dies, which at the same time consolidate the lining. A flanged strip a is fed by rolls B over a burner D, is cleaned by acid applied at c, is tinned by solder fed in strip form at F and smoothed by a copper bit H, is coated with Babbitt-metal at J, and passes through consolidating-rolls L, which may be cooled. The strip may be cut into lengths by dies or by saws, and the blanks are placed on a sectional die 11 held together by bolts, and are bent and consolidated by a die N operated by a press working at about 50 strokes per minute. The die 11 is formed with an ejector plunger 15. The strip a is prepared by bending a plane strip between rollers and upsetting the flanges so produced to increase their thickness. The flanging may be effected after the lining has been applied. The cleaning, tinning, and lining may be performed by hand. The Specification as open to inspection under Sect. 91 (3) (a) stated also that the lining may be applied in sheet form and secured by soldering. The presses may be employed to produce unflanged brasses. This subject-matter does not appear in the Specification as accepted.
