Abstract
An improved wick-holder for mounting a felt lubricating wick is provided with a passive inertia-activated pump mounted for submersion in the axle-cap lubricant-reservoir at a level that ensures that for all levels of the reservoir, the pump inlet is submerged in the lubricant of the reservoir. In a first embodiment, the passive inertia-activated pump takes the form of a piston-type pump, while in a second embodiment, the passive inertia-activated pump takes the form of a diaphragm pump. In either embodiment, the inlet of the passive inertia-activated pump is submersed in the lubricant-reservoir, and the output of the passive inertia-activated pump is directed to the surface-interface between the felt wick and the axle journal surface-area to increase the lubrication thereof over and above that which normally ensues owing to the conventional capillary action of the felt wick. In a modification of the first embodiment, the piston pump is mounted to a splash sleeve forming part of the wick-holder and which is telescopingly received over the free end of the felt wick, with the output of the passive inertia-activated pump delivering the lubricant to the surface-interface between the fel…
