This lubricator is intended for oiling at one and the same time both of the
piston cylinders of a locomotive steam engine, and for this purpose it has an oil
reservoir A-whose interior space is divided into two separate chambers B and B
by a partition C going through it at its axis-such partition having at its middle
an enlargement or vertical column D extending from top to bottom of the
reservoir.
The said column has through it, lengthwise or vertical passages m and m² and n'
and n-The two passages m and m¹ have tubes o and o¹ (see Fig. 1) leading down
from them into a cylindrical tube or chamber arranged below the oil reservoir and
opening at its ends into two pipes F and F¹, which in practice communicate with
the valve chests of the two engine cylinders. The said chamber is provided with
two cranks G and G' for either opening or closing communication with it and the
said pipes F and F¹. The plug p of one of these cocks has a hand lever p³ fixed

page_text: to it, see Figs 1 and 2, the plug p₁ of the other cock having a crank q extending
down from it, and connected with the shorter arm q¹ of the said lever by a curved
link, which is pivoted to the said crank and arm. On moving the lever both
plugs will be simultaneously turned so as to either close or open communication
between the chamber E and the pipes F and F".
The link has a rectangular notch s made in it at its crown as represented,
there being projected into the notch from a standard H extending from and below
the chamber E a figure I, having down the middle of its outer end a vertical
mark t, which with other marks u, v, w, made on the link, indicate when the
cocks G and G¹ are fully or partially opened or are closed.
The standard H has within it a chamber w¹ from which a tubular neck v¹ projects
upward between the pipes o and o¹, as shown in Fig. 1. There is within the upper
part of the neck v, a check valve w', which is to prevent oil from being discharged
from the lubricator into the boiler.
The steam from the boiler passes into the chamber u¹ by means of a conduit x,
provided with a stop cock y, see Fig. 2. From the hollow neck v¹ partitions z, 2
(see Fig. 5) extend diametrically across the chambers E from the bottom thereof to
the top of the neck. These partitions with neck serve as barriers to prevent the
oil that may flow out of either of the tubes o and o' from passing backward out of
its true course into the pipe For F¹.
From the chamber E, the steam passes upward through the passages n and n²,
in the column D, and thence through pipes a² and a³, leading from the top of the
column upward into the condenser K, see Figs 1 and 2. At their upper parts the
passages m and m¹ are provided with screw plugs 62, 63, to their mouths-such
plugs being to regulate the flow of oil from the reservoir A into the said passages.
At the upper part of the oil reservoir A is the sight feed L, which is a tubular
projection provided with a glass pane c¹, arranged within and across it. In rear of
the glass pane and the column D, there is a chamber d', that at top opens into the
condenser. From this chamber a passage e' leads through the partition C toward
the glass pane, and is provided with a screw plug f¹, for regulating the flow of
water from the condenser into the said passage. From the passage e¹ two branch
conduits g', g, lead to two vertical flutes h², h³, of a mirror or reflector i³, which on
its front bears closely against the rear face of the glass pane. The concave grooves
or flutes h², h³, extend vertically through the front face of the mirror. The drops
of water from the passage el, pass down through the tutes and directly in rear of
the glass pane, and thence into the oil reservoir, into which the flutes at their
lower as well as their upper ends open,
On looking upon the glass pane, a spectator can see the drops of water as they
pass from the condenser through the flutes, from which they run into the chambers
of the oil reservoir. As the water of condensation may accumulate in such
chamber, it will sink below the oil therein, and cause it to flow into the passages,
leading from them into the chamber E from whence such oil will be carried to the
engine cylinders by the steam when passing in opposite directions out of such
chamber and into the valve chambers of such cylinders.
Above the passage e¹ there is to the oil reservoir, a cylindrical induct or oil
feeding mouth k¹, closed at its bottom and provided with a screw stopple that
screws into such mouth, down to the said bottom thereof, and serves to close two
branch passages m², leading laterally out of the said mouth k¹, and into the
chambers B and B¹. On withdrawing the stopple from the mouth k¹, and pouring
oil into such mouth, such oil will flow at once through both' the branch passages m²,
into the said two chambers B and B¹,
At the lower part of the oil reservoir there is a drainage cock M, which com-
municates with the two chambers B and B¹, by two separate passages n³, see Fig. 6,
they being to drill both chambers at once when the cock M is opened. Extending
diametrically across the neck 02, at the base of the oil reservoir, there is a bar p*,
triangular in transverse section in that portion of it which crosses the passage q
and arranged as represented in Figs. 1, 2 and 8. This bar answers two purposes,

page_text: viz, as a stop to check the rise of the valve w, and as a means of dividing the stream
of oil when escaping from the oil reservoir through said passage gå, leading through
the bottom thereof into the chamber E. This division of the stream is to cause it
to flow as nearly equally as possible down opposite sides of the neck v¹, thence into
the chamber E.
In the lower part of the oil reservoir A, is another chamber r², having within it
a screw plugs, to open or close the passage 9 such chamber having passages u³,
opening laterally from it into the chambers B and B¹, see Fig. 6. On drawing
back the screw plug so as to uncover the passages q³ and u, the oil from the two
chambers B and B may be discharged directly into the chamber E-such being
to allow of the lubricator being used like an ordinary "tallow cock' when
necessary.

Instead of steam being introduced into the lubricator at its lower part as
described, it will be let into the condenser at its upper part, such condenser being
shown in the drawings as having an opening a³, in its crown-into which opening
a plug y is screwed. On removing the plug from the opening a pipe leading
therefrom to the boiler may be screwed into the opening-such pipe boing shown
at z in Fig. 3.
The oil reservoir, its cross partition, and the column extending up through the
latter, are cast or founded in a single piece of metal-coupled with and opening
into the chamber E or part containing such as shown in the drawings.
From the above it will be seen that the hereinbefore described lubricator is a
duplex one, it having with its oil reservoir, a single condenser--and besides it has
in the oil reservoir, not only the divisional partition but within such partition at
its middle and projecting in opposite directions from it, a column, integral or in one
piece with it and the reservoir-and having four passages m, m', n and n³, leading
upward through it the said column-Furthermore, the reservoir has a "sight feed
through which the drops of water as they pass from the condenser to the two
sections or chambers of the reservoir, can be seen through one pane, they at the
time passing down through the two flutes of the reflector.
The oil reservoir has a chamber below it into which it opens and from which
pipes are led in opposite directions to the valve chests of the two engine cylinders,
such pipes being provided with stop cocks simultaneously operated by a lever and
mechanisin and index finger-as herein before explained-such being to close the
oil passages to the cylinders without requiring any interference with the valves or
cocks, that in the upper part of the reservoir regulate the feed of the water of
condensation from the condenser through the sight feed and into the oil reservoir-
With my lubricator it is not necessary as with most if not all others to allow a
small jet of steam to pass into the engine cylinders, on the steam being cut off at
the throttle valve, such jets often being productive of injurious effects, as on a
stoppage of the locomotive-these jets are apt to accumulate steam in the cylinders,
so as to render it difficult to start the engine either forward or backward. The
simple mechanism adopted by me, and bereinbefore described, for opening and
closing the steain ducts from the oil reservoir to the valve chests of the cylinders-
enables an engineer to overcome this difficulty by operating the valve lever,
without any necessity of moving the plugs of the feed cocks of the lubricator. The
oil that in the interior may pass into the exit chamber below the oil reservoir-
becomes stored in such chamber while the cocks at its ends are closed and instead
of being wasted, is ready for use when they are next opened-By having the sight
feed constructed as described, the rate of feed of the drops of water in their passage
to the two sections of the oil reservoir, can be seen at once through a single pane,
rather than through two separate ones, the duplex fluted or concave light reflector
cominunicating with the oil reservoir both at top and bottom thereof-and also
with the condenser, as described.
Furthermore, the draining devices at the bottom of the oil reservoir, serve to
drain it entirely or in case of accident to enable the lubricator to be used as an
ordinary "tallow cock," and in so doing to feed oil at once to both of the cylinders.
