Description: |
| Abstract:
My invention relates to that class of oil-cups from which the lubricant is introduced to the cylinder, or other point of application, against the pressure of steam, and also to such as should furnish a constant supply of oil; and It consists in so constructing the globe that, after it has been filled with oil or tallow, it will allow a small quantity to pass continually to the point where it is needed, till it is all exhausted. This is effected by constructing the globe with a discharge-pipe, passing through the bottom to the point of delivery, and rising within it to near the top. The steam rises through this pipe, and a small portion is constantly being condensed. This condensed water, by its greater gravity, sinks to the bottom of the globe, and thus raises the oil, so that it flows down the tube, and supplies a small quantity continually, till the globe is full of water, and the oil or tallow is exhausted. The water is then drawn off by a cock at the bottom, and the globe again filled with oil. A small float is so arranged in the upper part, that, when the globe is full, it rises and closes the supply- tube, and shows that enough has been introduced, after which the process goes on as before.
Claim:
In combination with the globe A, the tube B, extending to near the top, and the screw E, for regulating the supply. |
