LUBRICATOR FOR STEAM-ENGINES.

SPECIFICATION forming part of Letters Patent No. 414,785, dated November 12, 1889.

Application filed July 13, 1889. Serial No. 317,407l (No model.) i

To all whom it may concern:

Be it known that I, CLAUDIUs VERNIAUD, a citizen of the United States, residing atQ uincy, in the county of Adams and State of Illinois, have invented certain new and useful Improvements in Lubricators for Steam-Engines,

' dsc.; and'I 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 appertains to make and use the same.

My invention has relation to improvements in lubricators for steam-engines of that class wherein the oil is discharged by hydrostatic pressure excited by a column of water. Heretofore, so far as I am aware, in oil-ejectors of that class acting to fioat the oil through a column of water, the drop of oil as it forms at the point of the nozzle of the ejector is retarded and enlarged, owing to the low temperature distributed from the body of the apparatus. At times -under circumstances of heavy feed the water is forced from the gageglass and the oil accumulated therein, obscuring the glass and preventing observation of the amount of oil being fed. This discharge of water and observation of the glass render it necessary to refill and clean the glass, which manipulation sometimes breaks the glass, especially when the steanrpressure is high, and also at times burning or otherwise injuring the attendant.

The object of my invention is to provide an oil-ej ector wherein these object-ions or defects are avoided and the oil fed through a column of water maintained at a high temperature.

I accomplish the object of my invention by the means cr apparatus illustrated in the accompanyin g drawings, wherein- Figure 1 is a central sectional view of my improved oil-ejector attached to a steam-pipe of an engine'. Fig. 2 is a central sectional view of the oil-ejector, on larger scale than shown in Fig.1,sl1owing the fittings, the glass tube, and oil-ejector.

A designates the oil-reservoir, which may be of any proper form to serve the purpose. In the cover of the reservoir is a iilling-oritice threaded to take the screw-plug l, and in the bottom is iitted a drain-pipe 2, provided with a turning plug to open and close the pipe. In the reservoir isa pipe 3, extending well down into the reservoir and provided with a stop-valve 4E. On the end of the pipe 3 is attached the chamber 5, constituting the condenser for the steam which may be admitted thereto. In the reservoir is a verticallyarranged pipe G, having its upper end approaching nearly to the top of the reservoir, and to the lower end is fitted a joint-pipe 7,

opening into the ejector pipe or chamber 8,l

in which are arranged the stop valve 9 and ejector-pipe l0, substantially as seen in the drawings.

B designates a steam-supply pipe leading' from the engine or steam source. At a point in this steam-pipe is 'tted the end of a steamconduit pipe 1l, having mounted on its outer portion a valve-fitting i2, connected by a pipe 13 to the upper end of the condenser. The lower end of the valve-fitting 12 is connected to a pipe 14, which is 4in turn connected to the joint-piece l5, having a pipe 16 with a valve-seat leading back into the steam-pipe B'. An arm a of the joint-piece l5 is fitted in the shell of the reservoir and serves to heat the Oil in the reservoir. In the lower end of the joint-piece l5 is properly joined the glass tube 17, in which the oilejector is located, substantially as shown. The arrangement of these pipes and fittings or joint-pieces with their valves constitutes a steam-circuit, by which the hot steam is brought directly in scontact with the contents of the glass, and in combination with the other elements of the apparatus forms the gist of my invention.

The operation of my improved apparatus is as follows: Supposing the attachments to be made, as speciiied, to the vertical steampipe of an engine and the reservoir as supplied with oil, the valves in the upper and lower branches l1 and 16 beingopen, a constant current of steam will pass into the pipe 14, and also pass through into the condenser, from whence it will be deposited into the reservoir and keep t-he oil therein at a proper height. The effect of the current of steam through the pipes having direct connection with the steam-pipe also forces the steam into the column of water in the glass, thus heating the parts. This water being in contact with the steam is raised to a high tempera IOO ture and delivers the oil heated to the action of the steam-current, which forces it to the parts to'be lubricated. f

The advantages of this arrangement are, first, the action of steam-current through the tubes in connection with the steam-pipes renders it impossible for the oil to congeal and clog up the discharge-orifice of the pipe, since it makes the discharge of the oil continuous and blows it into atoms into the line of steam before entering into the engine; second, if it is necessary to feed the stream of oil into the engine, the water in the glass will not be displaced, as it would be without this steameurrent, which serves to keep the glass full at all times by the deposition of water from partial condensation of the steam passing` through the pipe above the glass.

That I claim isl. In combination with a lubricator in which the oil is fed through a column of water, a steam-supply pipe, another steam-pipe interposed between said stealnsupply pipe and the lubrieator proper, connecting-pipes between said first-mentioned pipe, ttings at the ends of said second steanrpipe, an ejector attached to the lower one of said fittings and connected with the oil-reservoir, and suitable regulating valves, all substantially as described.

2. In combination with a condensation-displacement lubricator, a steam-pipe intermediate the stea1n-supply pipe and the lubricator proper, connecting -pipes between said irst-mentioned pipe, and upper and lower fittings adapted to receive said connecting and intermediate pipes, the upper fitting also serving as a conduit for steam to the condensing-chamber, and the lower tting also sei-2 ing as a support for the oil-reservoir, substantially as described.

In testimony whereof I aiix my signature in presence of two witnesses.
