WILLIAM PHILLIPS THOMPSON, of the Firm of W. P. Thompson & Co., Patent
Agents, of 6, Lord Street, Liverpool, in the County of Lancaster, and 323,
High Holborn, in the County of Middlesex, and Berridge Street, Leicester, in
the County of Leicester, Civil Engineer. "IMPROVEMENTS IN LUBRICATING
APPARATUS FOR STEAM ENGINES AND OTHER MACHINERY WILERE STEAM IS
USED." A communication from abroad by Joseph Vincent Renchard and John
Joseph Rencbard, both of Detroit, in the State of Michigan.
This Invention consists in two reservoirs arranged in a vertical position one
above the other, a diaphragm which closes the direct communication between the
reservoirs, a trunk for attaching the reservoirs to a steam pipe provided with two
passages, one communicating between the steam pipe and water reservoir, and the
other between the steam pipe and oil reservoir, a glass tube or gage arranged in a
vertical position in front of the oil reservoir, and communicating with it at both
upper and lower ends, whereby the quantity of oil in the reservoir and the flow
or feed are readily observed.
The principal parts of the apparatus are as follows:-
A water reservoir, an oil reservoir, a diaphragm closing direct communication
between the respective reservoirs, a trunk by which the lubricator is attached to
the steam pipe, a steam passage in said trunk through which the steam enters the
water reservoir, an oil passage also in said trunk through which the oil is forced
from the lower reservoir into the steam pipe, a vertical tube which communicates

page_text: with the steam passage in the trunk and conducts the steam to the top of the
water reservoir, a water tube in the oil reservoir which conducts water from the
water reservoir downward and upward through the oil reservoir and out through
an orifice, where it escapes drop by drop, falling through a glass tube, an upper
and lower screw valve.
The apparatus is operated as follows:-The oil reservoir is first filled with oil,
which is introduced through the glass tube by removing a screw plug. This plug
is then replaced, and the upper screw valve is slightly withdrawn. The steam as
it enters the reservoir is gradually condensed into water, when it flows downward
through a passage in the diaphragm and enters the water tube in the oil reservoir
when it is conducted by said tube downward and upward through the reservoir,
escaping in drops as mentioned outside of the reservoir above the glass tube, and
through the latter to the bottom of the oil reservoir. It is obvious that the oil
stands at equal height in the oil reservior and tube; thus as the water escapes the
drops can readily be seen as they descend through the oil, as the drops of water
displaces an equal quantity of oil; it is obvious that by observing the flow of water
the escape of oil is readily ascertained, and that by regulating the flow of water
the escape of oil is regulated. The flow of water, and consequently the flow of oil,
is regulated by adjusting the upper screw plug. The water in the water reservoir
is kept hot by the influx of steam. The heated water thus passing through the
tube immersed in the oil reservoir warms the oil and retains it at the proper
temperature and consistancy.
As the water thus enters the oil reservoir, owing to its greater gravity it buoys
up the oil and forces it out through the oil passago in the trunk into the steamı
pipe regulated by scrow valve if desired. The body proper of the lubricator, con-
sisting of the two reservoirs and trunk is cast or formed in three picces, which are
united together by screw-joints. The glass tube or gage is connected at its
respective ends to the oil reservoir by joint or glass cages (so called) to which it is
closely fitted by packing and packing nuts.
The passages in the projecting end of trunk terminate in two pipes, the one
leading to the steam passage enters it from above, while the tube entering the oil
passage extends in the opposite direction downward several inches below the
trunk that the escaping oil may not enter the water tube. The orifice of the oil
tubo is formed at an obtuso anglo to the tube, which peculiar shape facilitates the
action of the steam upon the oil in converting it into spray.
As the water accu-
mulates beneath the oil in the reservoir it becomes necessary to eject it and the
sediments from the oil therefrom.
To accomplish this end the bottom of the reservoir is provided with a siphon
passage which is closed by the lower screw valve. By partially withdrawing this
screw valve the water and refuse matter are by the action of the siphon and
pressure of the steam expelled out through the passage. The mouth of this passage
is provided with a nozzle for attaching a hose or pipe with which to convey the
water ejected to a receptacle therefor.
The screw valves are each surrounded with packing to prevent the contents of
the lubricator from escaping.

WILLIAM PHILLIPS THOMPSON, of the Firm of W. P. .Thompson and Co.,
Patent Agents, of 6, Lord Street, Liverpool, in the County of Lancaster, and
323, High Holborn, in the County of Middlesex, and Berridge Street, Leicester,
in the County of Leicester, Civil Enginecer. "IMPROVEMENTS IN LUBRICATING
APPARATUS FOR STEAM-ENGINES AND OTHER MACHINERY WHERE STEAM IS
USED." A communication from abroad by Joseph Vincent Renchard and John
Joseph Renchard, both of Detroit, in the State of Michigan.
This Invention relates to improvements in lubricators or apparatus for injecting
oil into the steam pipes of engines when under pressure. It consists of two
reservoirs arranged in a vertical position one above the other, a diaphragm which
closes the direct communication between the reservoirs, a trunk for attaching the
reservoirs to a steam pipe provided with two passages, one communicating between
the steam pipe and water reservoir, and the other between the steam pipe and oil
reservoir, a glass tube or gauge arranged in a vertical position in front of the oil
reservoir, and communicating with it at both upper and lower ends, whereby the
quantity of oil in the reservoir and the flow or feed are readily observed.
Fig. 1 is a perspective view of the Invention; Fig. 2 is a vertical section drawn
on a line with and through the trunk, by which it is attached to the steam pipe;
Fig. 3 is a vertical section drawn at right angles to the connecting trunk.
The principal parts of the apparatus are as follows:-A is the water reservoir;
E is the oil reservoir; D is the diaphragm closing direct communication between
the respective reservoirs; C is the trunk by which the lubricator is attached to
the steam pipo; G is the steam passage in said trunk, through which the steam
enters the water reservoir; H is the oil passage, also in said trunk, through which
the oil is forced from the lower reservoir into the steam pipe; I is a vertical tube
which communicates with the steam passage G, and conducts the steam to the top
of the water reservoir; K is a water tube in the oil reservoir which conducts water
from the water reservoir A downward and upward through the oil reservoir E and
out through the orifice E¹, where it escapes drop by drop, falling through the glass
tube M; U and V, upper and lower screw valves.
>
The apparatus is operated as follows:-The oil reservoir E is first filled with
oil, which is introduced through the glass tube M by removing the screw plug Q.
The plug Qis then replaced; and the upper screw valve U is slightly withdrawn.
The steam as it enters the reservoir is gradually condensed into water, when it
flows downward through the passage J in the diaphragm, and enters the tube K,.
when it is conducted by said tube downward and upward. through the reservoir,
escaping in drops, as mentioned, outside of the reservoir, above the glass tubo M,
and through the latter to the bottom of the oil reservoir. It is obvious that the
oil stands at equal height in the oil reservoir and tube; thus as the water escapes
the drops can readily be seen as they descend through the oil, as the drops of water
displace an equal quantity of oil; it is obvious that by observing the flow of water
the escape of oil is readily ascertained, and that by regulating the flow of water
the escape of oil is regulated. The flow of water, and consequently the flow of oil,
is regulated by adjusting the upper screw plug Ū. The water in the reservoir A
is kept hot by the influx of steam. The heated water thus passing through the
tube K immersed in the oil reservoir, warms the oil, and retains at the proper
temperature and consistency.
As the water thus enters the oil reservoir, owing to its
up the oil and forces it out through the opening T and
greater gravity it buoys
passage H into the steam

page_text: pipe regulated by screw valve if desired. The body proper of the lubricator, con-
sisting of the reservoirs A, E, and trunk C is cast or formed in three pieces which
are united together by screw joints a and b. The glass tube or gauge M is connected
at its respective ends to the oil reservoir by the T joint, or glass cages (so called)
N and O, to which it is closely fitted by the packing P, P, and packing
nuts A¹, A¹
The projecting end of trunk C is provided with tubes x and Y, which respectively
communicate with the respective passages G and H. Tube x is curved upward, so
that the steam may enter it from above, while the tubo y extends in the opposite
direction downward several inches below the trunk, that the escaping oil may not
enter the tube G. The orifice of tube y is formed at an obtuse angle to the tube,
which peculiar shape facilitates the action of the steam upon the oil in converting
it into spray.
The passage T is closed and the escape of oil arrested by the
screw valve L.
As the water accumulates beneath the oil in the reservoir it
becomes necessary to eject it and the sediments from the oil therefrom.
To accomplish this end the bottom of the reservoir is provided with a siphon
passage g, which is closed by the lower screw valve V. By partially withdrawing
the screw valve V the water and refuse matter are by the action of the siphon and
pressure of the steam expelled out through the passage; the mouth of the passage g
is provided with a nozzle W for attaching a hose or pipe with which to convey
the water ejected to a receptacle therefor. The screw valves L, U, and V arc
each surrounded with packing h, h, h, to prevent the contents of the lubricator from
escaping.
Having now described the Invention exactly as communicated to me by my
American correspondents, with orders to file, I wish it to be understood that what I
believe to be now and desire to protect under the herein before in part recited
Letters Patent is,-
