Description: |
| Abstract:
This invention relates to those lubricators or oil-cups, which consist, essentially, of a reservoir or fount having a pair of heads that are clamped against the opposite ends of the fount by means of an axial tube; and the first part of my improvement consists in providing the lower end of the tube with a channel or other outlet that permits the discharge of oil, the flow of the same being regulated by an adjustable rod, ping, or stem traversing said axial tube. I prefer to regulate this discharge of oil by means of a conical valve at the lower end of the stem, which valve is readily adjusted with reference to a suitable seat, the latter being located at the bottom of the axial tube, although the same result can be obtained by means of a channeled rod, or ported plug operating in conjunction with openings in the side of said tube.
Claim:
The combination, in a lubricator, of a bodily-detachable tube that is screwed into the lower head and has a bearing upon the upper head of the oilcup or reservoir, said tube being provided near its lower end with with one or more inlets, a discharge-channel and a seat for the valve that regulates the flow of oil, which valve is carried by a rod or stem traversing said tube. |
