LUBRICATOR.
SPECIFICATION forming part of Letters Patent No. 746,883, dated December 15, 1903.
7 Application filed July 24, 1903. Serial No. 166,874. (No model.)
To 00% whom it may concern:
' Be it known that we, NORMAN SCHURMAN and EDWARD F. NHITED, citizens of the United States, residing at Garterville, in the county of Jasper and State of Missouri, have invented certain new and useful Improvements in Lubricators; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it apprevent the water raising above a certain level or height.
A further object of the invention is to provide means for preventing air and gases from accumulating in the apparatus, which would eventually exclude the steam from the system and allow the latter to cool below the temperature corresponding to the steam temperature at gage-pressure.
A still further object of the invention is to provide in a lubricator a steam column or chamber in communication with the sightfeed and a water chamber or column in communication with the lower end of an oil tank or reservoir and opening into the said steam column or chamber.
It is well known that in this class of lubricat'ors the oil is forced to feed by water-pressure, and such pressure depends upon the height of the water in the water-column. Therefore in all other lubricators known, to applicants the water may be nearly up to the top of the column or nearly down to the'bottom of the column, which will cause the rate of feed of the oil to vary accordingly. It is also Well known that if the sight-feed tube is,
full of air or gases to the exclusion ofsteam the temperature will not be uniform, and con' sequently the oil at the point of feed will have a variable temperature, and therefore a variable rate of feed. It is also well known that if air and gases arepermitted to accumulate in the condensing-chamber'steam will be excluded and the system will be'deprived of the water necessary for forcing the oil to feed. It is therefore the purpose of this invention to overcome such objections, defects, and disadvantages and tofurnish a lubricator wherein the temperature of the oil at the point of feed will-be as uniform as the temperature of thelive steam, which practically varies only according to variations in the steam gage pressure.
In the accompanying drawings, forming part of this application, Figure l is a central vertical section of a lubricator embodying our invention. Fig. 2 is a cross-section on the line B B, Fig. 1. Fig. 3 is a section on the line A A, Fig. 1. Fig. 4: is a cross-section on the line C C, Fig. 2. Fig. 5 is a similar view on the line D D, Fig. 2. v
The same numeral references denote the same parts throughout the several views of the drawings.
The oil cup or reservoir 1 is of the ordinary type, having a removable plug 2 for filling the cup and a drain 3 at the bottom for letting off-water before refilling, an oil-port 4 at the top, and a water-pipe 5 at the bottom, a needie-valve 6, controlling the passage to a nozale 7 and having its casing connected to the cup by a stem 8 at the port 4, which stem forms a passage for the oil from the cup to the nozzle, the latter depending into a sightfeed glass tube 10. 7
A valve 11, connected to the main steamline 12, has a column 13 projecting therefrom, which is connected to the needle-valve casing by a stem 14, forming acommunieation or passage 15 between the sight-feed tube and the steam-chamber 16, formed by or in the column 13, the top of 'the sight-tube being held by the needle-valve casing, and the bottom of the said tube being supported by and in communication with a stem 17, leading from the chamber 16. A water-chamber 18 is formed in the column 13 and terminates at the top in a chamber 19, connecting with the top of the steam-chamber 16, so as to permit excess of water to overflow into the steamchamber, the bottom of the water-chamber being connected to the cup 1 by the pipe 5. The water and steam chambers open into the chamber 19 in such a manner that the latter constitutes a'condensing-chamber.
The means for relieving the apparatus of air or gases consists of a valve or petcock 20 in the top of the chamber 19, or in lieu of the petcock we may employ a circulating-pipe leading from the chamber 19 to the main steam-line.
In operation Water from the pipe 5 displaces the oil floating on the water in the cup, and the oil is forced through the port 4 to the nozzle,whence it drops through live steam in the sight-tube and is carried by the steam 17 to the steam-chamber 16 and from the latter to the main steam-line for purposes of lubrication. Live steam from the main line enters through the steam-chamber 16 to the condensing-chamber 19,where it is condensed into water, and the latter falls into the Watercolumn 18, whence it is carried to the bottom of the oil-cup by the pipe 5. It is obvious that the valve of the pipe 5, valve 11, and needle-valve all being open the pressure of water in the column 18 will force the oil to feed through the nozzle, and should there be more water condensed than is required to replace the oil fed out the water will overflow into the steam-chamber 16 and thence to the steam-line.
Having thus described our invention, what We claim as new, and desire to secure by Letters Patent, vis--- 1. In a steam-lubricator, the combination, with a suitable oil-reservoir, of a column having a steam-chamber in communication with the steam-line, asight-tube connected to the lower end of the steam-chamber, a needlevalve and its casing having stems connecting the reservoir and the said chamber with the said tube the valve being adapted to control the passage from the reservoir, a nozzle in the needle-valve casing depending into the sighttube from the valve-controlled passage, a Water-chamber formed in said column in communication with the steam-chamber, a pipe connecting the water-chamber with the reservoir, a condensing-chamber at the intersection of the steam and water chambers, and means connected with the condensingchamber for allowing the escape of air and gases.
2. In a steam-lubricator, the combination, with a suitable reservoir, and a sight-feed tube in communication with the reservoir at the top of each and having top and bottom connections with a steam-chamber, of the steam-chamber, a water-chamber adjacent to the steam-chamber and adapted to make an overflow of water into the said steam-chamher, a condensing-chamber at the juncture of the steam and Water chambers and being adapted to drain the latter, and a pipe connecting the water-chamber with the reservoir.
In testimony'whereof we affix our signa tures in presence of two witnesses.
NORMAN SCHURMAN.
