PROVISIONAL SPECIFICATION.
An Improved Lubricator.
1, JOHN PITT BAYLY, of 18 Fulham Place, Paddington, in the County of
London, Patent Agent, do hereby declare the nature of this invention (a communi-
cation to me from abroad by Charles Rueger, of Butte City, Montana, U.S.A.
Inventor,) to be as follows:-
This invention has reference to that class of lubricator commonly employed for
greasing the slide valves of engines, and the like.
By this invention a lubricator is constructed which consists of an oil reservoir
preferably constructed of metal, and tubular in section. This oil reservoir stands
near the steam supply-pipe, and contains a certain amount of water, which about
one third fills it. The oil for lubricating fills the other space, and rests upon the
water. A small steam-pipe projecting from the main supply-pipe enters the screw
cap of the reservoir, and projects down it to a point near the bottom thereof, and
beneath the surface of the water. This pipe is provided with a tap for regulating
the flow of steam into the water. At the top of this reservoir is secured one end of
a pipe which leads into a small oil chamber, located adjacent to the main supply-
pipe near its entrance to the steam chest. Suitable draw off taps and pipes are
arranged at the top and bottom of the lubricator reservoir respectively.
The operation is as follows:-Steam enters the reservoir through the pipe, which
passes down into the water and oil, and out through the pipe in the upper end of
the reservoir, and thence to the steam chest.

SPECIFICATION.
An Improved Lubricator.
I, JOHN PITT BAYLY, of 18 Fulham Place, Paddington, in the County of
London, Patent Agent, do hereby declare the nature of this invention (a communi-
cation to me from abroad by Charles Rueger, of Butte City, Montana, U.S.A.
Inventor,) and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
My invention relates to an improvement in force-feed lubricators, the object being
to provide means for utilizing steam, oil, and water pressure for creating a steady
and automatic feed of the lubricant and keeping such lubricant in constant
readiness to flow. A further object is to provide means for holding a considerable
supply of oil, whereby the time, labour, and attention usually requisite for keeping
the lubricator supplied are economized, and at the same time the entire quantity is
kept in good condition for being fed and is fed in quantities corresponding to the
amount of steam being used and the consequential speed of the engine or other
machine to which the lubricator is attached.
With these ends in view my invention consists in certain novel features of con-
struction and combinations of parts, as will be hereinafter described, and pointed
out in the claims.
The accompanying drawing is a view in side elevation, partly in section, showing
my invention applied to a steam-pipe.
A represents the oil-reservoir. This is preferably of cylindrical-form and can be
placed where most convenient, it only being essential that the oil should be kept

page_text: warm enough for the flow of any viscid engine-oils in cold weather. This reservoir
is furnished with a removable screw-plug G at the top, which is adapted to be
removed in order to fill the reservoir with the lubricant.
A pipe E, leading into the reservoir, conducts steam from the steam-pipe D and
discharges it beneath the oil. This steam, by virtue of its contact with colder
bodies, condenses, and the water formed fills the pipe E and settles at the bottom
of the reservoir, discharging the oil at some point above as soon as an outlet is
formed for it.
Pipe F, leading from the upper end of the reservoir, carries off this lubricant as
it is required for use and displaced by the water from beneath. From the pipe F
the oil is discharged into the supply-chamber B of the oil-cup and thence it passes
through the regulating-valve J into the sight-feed tube J' above it. From this point
the lubricant passes into the steam-pipe D just above the throttle-valve C in the
case illustrated. As pipe E is connected with the same steam-pipe D, the same
pressure is maintained on both sides of the oil, thus keeping it balanced, and the
feeding of the oil is effected principally by the pressure of the column of condensed
water in pipe E and the siphon action of pipe F.
The valve H, or glass indicator, if preferred, in the reservoir A is for the purpose
of indicating when the oil has been displaced at this point by the water, when the
latter is removable through the pipe I at the bottom of the reservoir. The discharge
from the pipe H' and I is run into one settling-tank, so that valuable oil can be
saved for further use.
It is evident that slight changes might be resorted to in the form and
arrangement of the several parts described without departing from the spirit
and scope of my invention, and hence I do not wish to limit myself to the exact
construction herein set forth, but claim the application of a large storage-
reservoir for oil, when arranged to supply the oil automatically by the means
described or their equivalent, in connection with any lubricating-cup or other
device, the generally-limited storing capacity of which makes frequent attention to
them necessary. The principle is applicable in any case where an overbalance of
pressure can be created which will force the oil in the direction of the parts to be
Lubricated, by means of steam, water, air, or the gravity of the oil itself.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what I
claim is :
1. The combination, with an oil-reservoir, a steam-pipe, and a pipe leading from
the latter into the oil-reservoir and terminating at or near the bottom of the latter,
of an oil-discharge pipe leading from the reservoir at or near its top for discharging
the oil into the steam-pipe as it is required for use, and a draw-off pipe leading
from the reservoir near the top of the latter, but below the oil-discharge pipe, and a
pipe leading from the reservoir at or near the bottom of the latter, substantially as
set forth.
2. The combination, with an oil-reservoir, a steam-pipe, and a pipe leading from
the latter into the oil-reservoir and terminating at or near the bottom of the latter,
of an oil-discharge pipe leading from the reservoir at or near the top, a small oil-
chamber into which said oil-discharge pipe discharges its contents, connections
between the small oil-chamber and the steam-pipe, a draw-off pipe leading from the
oil-reservoir near the top of the latter but below the oil-discharge pipe, and a pipe
leading from the lower end of said reservoir, substantially as set forth.
