Description: |
| Abstract:
This invention relates to those lubricators io or oilers that employ two separate and distinct chambers, the tipper one of which contains the lubricant, while the lower one serves as a sight-chamber that renders the feed visible, and the first part of my improvement comprises a novel construction of the device whereby the sight-chamber can be readily kept clean and transparent, which result is accomplished as follows: The sight-chamber is located between the lower and intermediate heads of the lubricator, and the metallic member or cage that clamps these two heads together is situated within said chamber, thereby affording a smooth and unobstructed exterior of the latter that prevents the accumulation of dust and grease thereon and renders it an easy matter to clean the same.
Claim:
The combination, in a lubricator, of the collared tube C c, perforated head B b', and 3a swinging spring-scutcheon D, said scutcheon having a stump or projection, d', and an eye, d, which eye surrounds the collar c. |
