Description: |
| Claim:
This invention relates to various improve- mnents which I have made in the system of lubricating by capillary attraction and vacuum, based on the employment of Malacca cane or Indian rattan, or of any other vegetable sufficiently porous to serve properly as an intermediate conducting agent between the reservoir of oil and the shaft to be lubricated. |
