EDGAR ISAAC HENRY EDWARD WHITEHOUSE, of Coseley, in the County of Stafford,.
Manufacturer, and JOSEPH TRUBSHAW WHITEHOUSE, of Coseley aforesaid, Nining
Engineer. "A NEW OR IMPROVED LUBRICATOR FOR LUBRICATING THE CYLINDERS
OF STEAM ENGINES, AND FOR OTHER LIKE PURPOSES."
Our Invention consists of a lubricator constructed in the manner herein-after
explained, which lubricator is especially adapted for the lubrication of the cylinders
of steam engines, but is also applicable to various other like purposes, such, for
example, as the lubrication of the cylinders of other motive-power engines and other
machinery with hollow cylinders having pistons working in them, the upper side of
the piston being alternately under pressure and exhaust.
We will describe our Invention as applied to the cylinder of a steam engine.
We construct a lubricator according to our Invention in the following manner :-
To the bottom of a cistern or reservoir for the oil or other lubricant we affix by
screwing or otherwise a tubular stem. The upper part of this tubular stem projects
a short distance into the reservoir, and the lower end is made into a screw, which
takes into a concave screw made in the cylinder cover of the steam engine, and by
which screw the lubricator is fixed in its place on the cylinder. Valve seats are
made at the top and bottom of the tubular stem, and valves on opposite ends of
the same valve stalk fit upon the said valve seats respectively.

page_text: When the valve stalk is in its raised position, the lower valve is closed and the
upper valve open. When the valve stalk is in its lowered position, the upper valve
is closed and the lower one open.
The upper valve is attached to the stalk by screwing thereon, so that it can be
adjusted to a higher or lower position on the stalk. In this way the range of motion
of the valves and the rate of flow of the lubricator through the upper valve can be
regulated.
When the valve stalk is raised, the upper valve is open, and oil can flow through
it into the hollow tubular stem, in the axis of which the valve stalk works, the
quantity flowing in a given time depending on the adjustment of the upper valve.
When the valve stalk is lowered, the top valve is closed and the lower one
opened, and the oil which had accumulated in the hollow stem flows into the
cylinder.
The top of the cistern or reservoir containing the lubricant is closed by a
screw cap.
The upper valve is covered with a perforated cap to prevent the solid particles
passing to the valve and interfering with its action.
The action of the lubricator is as follows:-The reservoir of the lubricator having
been filled with oil or other lubricant, and the top of the reservoir closed by its
screw cap, the lubricator is secured to the top of the steam engine cylinder by the
screw at the bottom of its hollow stem.
When the piston of the steam cylinder is performing its descending motion, and
steam under pressure is above the piston, the said steam by its pressure closes the
lower valve of the lubricator, and oil flows through the upper valve into the hollow
stem.
When the motion of the piston is reversed, and the upper end of the cylinder is
connected with the exhaust, the lower valve opens and the upper valve closes, and
the oil accumulated in the hollow stein runs into the cylinder. Thus each time the
piston makes a descending motion, a regulated quantity of oil enters the cylinder,
the delivery of the oil ceasing when the steam engine is stopped, and recommencing
when it is again put to work.

OF STEAM ENGINES, AND FOR OTHER LIKE PURPOSES."
Our Invention consists of a lubricator constructed in the manner herein-after

of steam engines, but is also applicable to various other like purposes, such, for
example, as the lubrication of hollow cylinders having pistons working in them, the
upper side of the piston being alternately under pressure and exhaust.
We will describe our Invention as applied to the cylinder of a steam engine.
We construct a lubricator according to our Invention in the following, manner :-
To the bottom of a cistern or reservoir for the oil or other lubricant we affix by
screwing or otherwise a tubular stem. The upper part of this tubular stem projects
a short distance into the reservoir, and the lower end is made into a screw, which
takes into a concave screw made in the cylinder cover of the steain engine, and by
which screw the lubricator is fixed in its place on the cylinder. Valve seats are
made at top and bottom of the tubular stem, and valves on opposite ends of the same
valve stalk fit upon the said valve seats respectively.
When the valve stalk is in its raised position, the lower valve is closed and the
upper valve open. When the valve stalk is in its lowered position, the upper valve
is closed and the lower one open.
The upper valve is attached to the stalk by screwing thereon, so that it can be
adjusted to a higher or lower position on the stalk. In this way the range of motion
of the valve and the rate of flow of the lubricant through the upper valve can be
regulated.
When the valve stalk is raised, the upper valve is open, and oil can flow through
it into the hollow stem, in the axis of which the valve stalk works, the quantity
flowing in a given time depending on the adjustment of the upper valve. When the
valve stalk is lowered, the top valve is closed and the lower one opened, and the oil
which had accumulated in the hollow stem flows into the cylinder.
The top of the cistern or reservoir containing the lubricant is closed by a
screw cap.
The upper valve is covered with a perforated cap to prevent solid particles
passing to the valve and interfering with its action.
The action of the lubricator is as follows:-The reservoir of the lubricator having
been filled with oil or other lubricant, and the top of the reservoir closed by its
screw cap, the lubricator is secured to the top of the steam engine cylinder by the
screw at the bottom of its hollow stem.
When the piston of the steam cylinder is performing its descending motion, and
steam under pressure is above the piston, the said steam by its pressure closes the
lower valve of the lubricator, and oil flows through the upper valve into the hollow
stem.
When the motion of the piston is reversed, and the upper end of the cylinder is
connected with the exhaust, the lower valve opens and the upper valve closes, and
the oil accumulated in the hollow stem runs into the cylinder. Thus each time the
piston makes a descending motion, a regulated quantity of oil enters the cylinder,
the delivery of the oil ceasing when the steam engine is stopped, and recommencing
when it is again put to work.
We will now describe, with reference to the accompanying Drawing, the manner
in which our Invention may be performed.
Figures 1 and 2 represent vertical sections of a lubricator constructed according
to our Invention applied to the top of a steam engine cylinder, Figure 1 representing

page_text: the bottom valve closed and the top valve open, and the lubricant from the reservoir
flowing into the hollow stem; and Figure 2 representing the bottom valve open and
the top valve closed, and the lubricant which had accumulated in the hollow stem
allowed to flow into the steam engine cylinder.
The same letters of reference indicate the same parts in both Figures of the
Drawing.
a is the cistern or reservoir of the lubricator containing the oil or other lubricant,
the top of the said reservoir being closed by the cap b, screwed on the axial screw c,
carried by the cross piece d. To the bottom of the reservoir a a tubular stem & is
fixed by screwing it into a screwed hole in the bottom of the reservoir, and the
bottom of the hollow stem is fixed to the top of the steam engine cylinder e by
screwing it into a screwed hole in the said cylinder, as represented. In the top of
hollow stem d is a valve seat f, and in the bottom of the said stem is another valve
seat gIn the said hollow stem d a valve stalk h works loosely, the said stalk
having on its end the valves i, k, the said valves fitting upon the valve seats f, g,
respectively.
The top valve i is capable of adjustment on its stalk ; this is effected by making
a screw on the top of the stalk and screwing the valve thereon, the said valve being
fixed in its place by the screw nut 7.
By means of the adjustable valve i the range of motion of the valves i, h, and the
rate of flow of the lubricant through the upper valve sent f may be regulated with
great nicety.
Over the upper valve i a perforated cap m is screwed for preventing solid par-
ticles passing to the valve and interfering with its action.
On the valve stalk being raised in the hollow stem d, the bottom valve k is
closed and the top valve i is opened, as illustrated in Figure 1, and the oil or lubri-
cant from the reservoir a flows through the open valve i into the hollow stem &;
and on the valve stalk h taking the lowered position, represented in Figure 2, the
top valve i is closed and the bottom valve le is depressed from its seat, and the oil
or lubricant which had accumulated in the hollow stein & flows through the open
bottom valve k into the steam engine cylinder c.
The position of the parts of the lubricator represented in Figure 1 is that which
they respectively occupy when steam under pressure is above the piston in the
cylinder e, and the said piston is making its descending stroke.
The pressure of the steam acting on the bottom valve closes the said valve k,
and raises the stalk h, and opens the top valve i, and oil or other lubricant from
the reservoir a passes into the hollow stem d, as before described.
The position of the parts of the lubricator represented in Figure 2 is that which
they respectively occupy when the upper end of the cylinder is connected with the
exhaust and the piston is making its return stroke. As soon as the exhaust is
open to the upper part of the cylinder e the valve stalk / descends in the stem d
and opens the bottom valve, and closes the top valve i, when the oil in the stem d
flows into the cylinder e, as before described.
By our Invention the parts of the lubricator are very simple in construction, and
are not liable to get out of order; a regulated quantity of oil or lubricant is delivered
into the steam engine cylinder at each descending stroke of the piston, the supply
of oil or lubricant being interrupted when the piston makes its ascending stroke
and when the engine is stopped, and recommencing when the engine is set to work
again.
Although we have only described and illustrated our Invention in connection
with a steam engine cylinder, yet it may also be applied to machinery having
pistons working in hollow cylinders, the upper side of the piston being alternately
under pressure and exhaust.
Having now described the nature of our Invention, and the manner in which the
same is to be performed, we wish it to be understood that we claim as our
Invention, a new or improved lubricator for lubricating the cylinders of steam
engines, and for other like purposes, the parts of the said lubricator being constructed

page_text: and arranged and operating in the manner herein-before described, and illustrated
in the accompanying Drawing.
In witness whereof, we, the said Edgar Isaac Henry Edward Whitehouse
and Joseph Trubshaw Whitehouse, have hereunto set our hands and seals,
this Twentieth day of September, in the year of our Lord One thousand
eight hundred and seventy-eight.
