| Abstract:
This invention relates to an improvement in lubricators for steam-engines for which Letters Patent were granted to me September 26, 1871 (#119,269).
In that patent the oil was taken up by the steam passing through the valve—that is to say, the construction and connection of the lubricator was such as to require that it be placed in a pipe through which the steam passed to the engine, the lubrication being produced by circulation. The object of this invention is to adapt the lubricator for attachment to the steam-chest independent of the steam-pipe by simply a tube from the chest terminating at the lubricator, whereby the steam at the end of each stroke sets back into the tube, performing the action known as pulsation; hence, instead of circulation, I now employ pulsation and this improvement adapts my lubricator to all places where such pulsation occurs.
Claim:
In combination with the chamber A and passage T with its valve, the chamber L connecting with the said chamber A, and provided with a single opening, P, to allow the steam to enter and return by the same passage. |
