Description: |
| Abstract:
This invention relates to those lubricators whose reservoirs are surmounted with a cup or bell-shaped receptacle, from which receptacle xo he oil or other lubricant flows into the reservoir as soon as the screw-plug is elevated by rotating a handwheel or crank located above said oil-receptacle. The first part of my improvements comprises novel construction of the lubricator, whereby, is the screw-ping is elevated from its seat to charge the reservoir with oil, the accumulated gases and steam are deflected against the sides and inwardly-projecting rim of the cup, instead of being thrown out violently on the person of the engineer. The second part of my improvements comprises a novel combination of devices, whereby I am enabled to dispense with channels or grooves or other oil-passages in the operating-stem of the screw-plug. The oilcup has a depending neck projecting into the reservoir, the lower portion of said neck being provided with a female thread, wherewith is engaged the male screw of the plug-stein, whose upper or exposed end carries a handwheel or other convenient rotating device. Situated between the screw and handwheel of this stem is a conical plug adapted to close against a suitable seat in the cup or neck when the supply of oil is shut off, but as soon as it is desired to charge the reservoir said plug is elevated from its seat, and the lubricant then flows through lateral ports in the neck and fills said reservoir.
Claim:
An improved lubricator consisting of the oilcup B', having an internal depending neck, C c, paired with one or more ports, Dl, and pro-vided with a slot, b, to receive the lug G, said plug being situated between the operating-screw E and the upper end of plug-stem F. |
