Abstract

268,034. Ball, F. L., Moulton, F., and L. W. Tools Co., Ltd. Dec. 24, 1925. Force-feed lubricating. - A lubricant chamber is accommodated wholly within the radial dimensions of the walls of a bearing liner and has a resiliently - controlled wall for maintaining pressure on the lubricant therein to feed it through a passage or passages to the bearing surface. A sleeve 13 of leather cloth is arranged around a tubular bush 10, the sleeve being secured to the bush at each end by being forced into a channel formed between an end flange 11 and a rib 14 being held therein by a ring 15 of lead wire. A tubular spring 16 is arranged around the sleeve and a metal sheath 18 is forced over the flanges to complete the liner. The bush 10 is provided on its interior surface with an annular channel 19 which is in communication with the lubricant chamber formed by the sleeve 13 through passages 27 and which is in register with a lubricant supply passage in the shaft or the like which is mounted in the liner, this latter passage being provided with a non-return valve. When lubricant is being supplied to the chamber, the sleeve 13 expands against the action of the spring 16 and, on removal of the supply means, lubricant is gradually forced from the chamber to the bearing surface through passages 12. In a modification, lubricant is supplied to the chamber through a passage in the end face of the bush, while, in a further modification, lubricant is supplied through registering openings in the bearing housing and sheath 18. Specification 3466/88 is referred to.
