Description: |
| Abstract:
The object of my present invention is to simplify the construction, and thereby diminish the cost of manufacturing, those devices which employ a spring-actuated plunger for effecting a discharge of "grease" or other turgid lubricant from a suitable cup, fount, or reservoir.
Claim:
The combination, in a grease-cup, of a fount or reservoir having a ventage, a spring-actuated piston for effecting a forced feed of the turgid lubricant, a cutoff for regulating the discharge of the same, and a hood or cover which is screwed to said fount and imparts the tension to said spring. |
