Description: |
| Patented in Canada, patent #CA-16,545.
Abstract:
The present invention has reference to lubricators for steam-engines in which the water formed by the condensation of steam is permitted or caused to descend into the oil chamber or cylinder, whereby the oil therein is displaced and caused to ascend from the chamber or cylinder through a suitable outlet. The means usually employed for obtaining the object above specified was the use of a short pipe or tube communicating with the supply of water of condensation, and extending down into the oil chamber or cylinder, to conduct the drops of water into and through the oil, and thereby displace an equal quantity of the oil and cause it to ascend into the steam-supply pike. The essential and important feature in this class of lubricators is to be enabled at all times by observation to ascertain whether they are properly and regularly working, or the drops of water from the condensation of the steam regularly pass into the oil.
Claim:
A drip-tube of a lubricator having its end highly polished to present a bright surface, and extended in close proximity to the transparent portion of the oil-cylinder. |
