reservoir referring to fig3 and 4 a wick 88 preferably of felt material or other material that would allow capillary action is used to transfer the lubricant from the reservoir to the top of the slide rod as demonstrated by the position of the upper portion of the wick the wick will be in contact with the top of a slide rod not shown that extends through the bearing 90 a vertical extending wick path 89 and a horizontally extending wick path 91 are provided for positioning of the wick the transfer is accomplished by capillary action along the wick the required pressure head to transfer the lubricant upward from the reservoir to the top of the slide rod is developed by the capillary action of fibers in the wick the distance that the lubricant can travel above the reservoir and the level of wear resistance depend on the type of material used in the wick in one embodiment a small diameter type f1 felt material with the highest capillarity or wicking height and highest resistance to wear may be used but variations are possible the amount or quantity of lubricant that is deposited on the slide rod is controlled by the size of the cross section area of the wick 88 and.
