Description: Patent for improvements in lubricators by mounting a box, with a pair holes near its ends, on a bearing; with partitions across the box adjacent each holes, a pair of cord shape wicks and a depending flange, depressing the wicks to the bottom of the box. “When the box filled with liquid lubricant and the cover closed, the lower edge of the flange depresses the wicks, submerging them at the center of the box, and the wicks absorb oil at this point, the oil is lead thence by capillary attraction along the wicks down through the holes in the bottom of the box and into the groove, whence it is delivered by direct contact upon the upper side of the rotating shaft which it is desired to lubricate.” (Lines 52-63) Illustration is included.
