Description: |
Abstract:
This invention relates to those lubricators, which employ an axial rod, stem, or plug for operating the valve or cutoff that regulates the discharge of oil and my improvement consists in utilizing the upper or outer end of the valve stem as a guide for a reciprocating stopper, which latter, when depressed, permits the cup or reservoir to be filled. Said stopper plays within a slotted or perforated cage or cylinder, and is maintained in its elevated or closed position by a spring that is preferably located within said cage and coiled around the valve-stem, the ascent of the stopper being arrested by the thumbpiece or other lateral projection of said stem. Furthermore, this cage and a spindle thereof act as a tie or hinder that unites the two heads of the cup, and said spindle or prolongation is usually provided with a valve seat, discharge-channel, and one or more ports that allow the oil to flow into said channel when the valve is opened.
Claim:
The combination, in an oil-cup, of a continuous or uninterrupted rod or stem for controlling the discharge of lubricant with a spring- actuated stopper adapted to reciprocate along the upper portion of said stem and uncover one or more inlets, and an inclosing cage or cylinder, the lower portion of said stern being screwed into a suitable bearing, and its upper end being passed completely through said stopper, thereby serving as a rigid guide for the latter, and permitting the stem to be removed without detaching the stopper. |
