"Vintage Machinery" entry for C. L. Hawes
Description:
Abstract:

The present improvements relate more specifically to the provision of means for automatically lubricating roller or ball bearings, in contradistinction to ordinary journal boxes. To the accomplishment of this end, I have combined a special form of lubricant elevating member with a device on the shaft whereby the lubricant thus elevated is caused to flow into the bearing where it is needed.

Claims:

1. In mechanism of the character described, the combination with a bearing comprising inner and outer rings and antifriction members held therebetween; of a well for lubricant; a peripherally grooved member mounted adjacent said inner ring, and a pendent closed member passing loosely around said grooved member adapted to elevate the lubricant, said grooved member being formed to cause such lubricant to flow between said rings, substantially as described.

2. In mechanism of the character described, the combination with a bearing comprising inner and outer rings and antifriction members held therebetween; of a well for lubricant; a peripherally grooved member mounted adjacent said inner ring, the flange on the side of said member contiguous to said inner ring being lower than the other flange and of approximately the same diameter as said ring; and a pendent closed flexible member passing loosely around said grooved member adapted to elevate the lubricant to the latter whence it flows between said rings.

3. In mechanism of the character described, the combination with a bearing comprising inner and outer rings and antifriction members held therebetween; of a well for lubricant; a peripherally grooved member mounted adjacent said inner ring, the flange on the side of said member contiguous to said inner ring being lower than the other flange and of approximately the same diameter as said ring; a pendent closed flexible member passing loosely around said grooved member adapted to elevate the lubricant to the latter whence it flows between said rings; and means for returning excess lubricant from said bearing to said well.
