Description: |
| Abstract:
My improvement relates to that description of lubricators which are used for oiling steam-cylinders or other vessels or bodies exposed to steam-pressure, and in which a cock or valve is used, constructed to shut off the steam-passage, and to open communication with the feed-inlet when it is required to charge the lubricator with oil, but which on being set or turned to lubricate, reverses the open and closed conditions of said passages, for the purpose of establishing an equilibrium of pressure above and below the oil- to secure its flow; also, in which the passage of the oil is effected by displacement of it from the reservoir or cup, by the water resulting from condensation of the steam admitted to said cap on opening its connection with the steam-cylinder. My invention in such relation consists in a peculiar construction of the cock and its seat or case, whereby the passage of oil through the lubricator may be increased or diminished, and quickened or retarded, by increasing or diminishing the surface of the cup exposed to condensation of the steam through varying the altitude, by the turning of the cock, at which the steam is admitted to the cup.
Claim:
The construction, in a lubricator of the character herein specified, of the cock C and its seat D, with their openings arranged substantially as described, whereby provision is made for varying the extent of steam-condensing surface in the oil-cup or reservoir of the lubricator, and thereby regulating the flow of oil or grease. |
