Abstract: A device for metering the flow of a fluid, such as a lubricating medium, at a controlled rate. The fluid is stored within a reservoir having a resiliently expandable wall which maintains the fluid under pressure. A transparent cover is provided for visual observation of the wall to indicate the volume of fluid in the reservoir. The pressurized fluid is directed from the reservoir through an elongate flow passage having a cross-sectional area which is sized in relation to the passage length to establish a predetermined rate of fluid flow. In one embodiment the device is automatically energized upon threading engagement with the opening of a structure to be lubricated, and can then be disengaged and stored in a partially full condition. In another embodiment the flow rate can be readily varied by changing the length of a circular flow passage, or the device can be energized or de-energized, by rotating the transparent cover.

Abstract: A bearing member positioned between an inner race surface and an outer race surface and urged into constant positive contact with said race surfaces by internal bearing spring forces. Predetermined contact areas are formed on the outer surface of said bearing member for contact with the outer race, and on the inner surface of said bearing for contact with the inner race. The bearing member is flexed between the inner and outer races within the range of elastic deformation of the bearing member material and is configured to cooperate with the inner and outer races to provide either radial or thrust load capability or a combination of both.
