Patents, of 67, Strand, in the City of Westminster, Civil Engineer. IMPROVE-
MENTS IN LUBRICATORS." [A communication from abroad by Charles Parshall, of
Detroit, State of Michigan, United States of America.]
The improvements consist in the construction of lubricators made to feed the oil
supply through a column of transparent liquid located between the oil reservoir
and the point to be lubricated by the combination of an oil reservoir with a steam
pipe conveying steam into the upper end of the said reservoir, and an oil pipe, the
inlet opening of which is below the outlet of the steam pipe, whereby a condensing
chamber is formed in the upper end of the oil reservoir of a transparent cylinder
located below the oil reservoir, and provided with an inverted syphon pipe which
connects with the oil pipe in the oil reservoir, whereby a column of oil is formed
to overcome the gravity of the column of water in the cylinder, together with an
oil and water supply regulating valves, arranged to govern the flow of oil from the
oil pipe in the reservoir to the syphon delivery pipe in the cylinder and the water
feeding conduits. The various parts can be of metal and the transparent cylinder
of glass. The shapes and dimensions of the reservoir and cylinder, as also of the
pipes and valves, may be varied to suit special circumstances.

HERBERT JOHN HADDAN, of the Firm of Herbert and Company, Solicitors of
Patents, of 67, Strand, in the City of Westminster, Civil Engineer. IMPROVE-
MENTS IN LUBRICATORS." A communication from abroad by Charles Parshall, of
Detroit, State of Michigan, United States of America.
The Invention relates to an improvement in lubricators and attachment for
locomotives, the object being to provide a lubricating apparatus of such construction
and arrangement of parts that the lubricator may be at all times under the
immediate control of the engineer or fireman, and the amount of lubricating
material supplied to the cylinders readily ascertained and regulated that both
cylinders of a locomotive engine be supplied from a single lubricating apparatus,
and that the connections may be adapted to expand and contract without injury
to the apparatus; and to these ends the Invention consists, first, in the combination
with the dry pipe of a locomotive boiler of a lubricator provided with a visible
hydrostatic drop-feed and with independent steam and oil pipes furnished with a
slip joint and connecting the lubricator with the dry pipe, whereby the amount of
oil fed to both cylinders is readily ascertained by the engineer and regulated as
desired.
The Invention further consists in the combination with the dry pipe of a
locomotive boiler of a lubricating apparatus connected therewith and with the
steam dome in such a manner that the connecting pipes may expand and contract
without causing any undue strain either on the lubricating apparatus, dry pipe, or
shell of the boiler.
Oil
The Invention further consists in the several details in construction and combi-
nations of parts as will be hereinafter explained and pointed out in the claims.
In the accompanying Drawings Fig. 1 is a vertical section of a lubricating apparatus
located within the cab of a locomotive and connected with the dry pipe in the
steam dome of the boiler; Fig. 2 is a view in perspective of the improved lubricator;
Fig. 3 is a transverse section of the oil receptacle; Figs. 4, 5, and 6 are modifi-
cations. A is the engine cab; B, the boiler; and D, the steam dome. Within the
dome D is located the ordinary dry pipe E, in the upper portion of which is
located the throttle valve F, all of which parts are of the ordinary or of any desired
construction. G is a lubricator supported by an upright frame a attached to the
boiler or to any convenient portion of the cab. It is preferable to secure upright a
to the boiler so that there will be no uneven motion between the body of the
lubricator and the conduits by which the connections with the dome are made.
Lubricator G is divided into two parts, viz., the oil receptacle b and condenser c,
which parts are constructed of metal and connected in any desired manner.
receptacle b is cast in a single piece with a recess d in one side thereof, within
which recess is placed the glass indicating tube H, the latter being of less length
than the oil receptacle to form openings e, f, leading from the upper and lower ends
of the glass tube to the interior of the oil receptacle. I represents a perforated
pipe, the upper end of which is screwed into the lower partition of the condenser,
while its lower end projects through the bottom of the oil receptacle and receives a
nut which latter being turned as a ball which fits snugly into a socket in the
bottom of the oil receptacle serves to bind evenly the latter to the condenser, the
upper edge of the oil receptacle being received within the downwardly projecting
Bange h formed on the bottom of the condensing chamber. Waste cock g¹ is
combined with nut g for the purpose of drawing off the water from the glass tube
and oil receptacle when desired. J is a screw threaded plug fitted into the top of
the condensing chamber. The plug J being removed oil is inserted through the
opening and flows into the perforated tube I, and from thence into the oil
receptacle. Condensing chamber c is provided with a screw threaded limb or
.

page_text: tem K, which is divided into a steam passage and on fecig passage
neans of the portion N. In the bottom of the condenser is located a downwardly
closing check valve j, by means of which a communication may be established
between the oil receptacle b and the oil passage M.
Connecting with the steam passage L is a vertical steam pipe or conduit k which
extends nearly to the top of the chambered nut 1. Nut being chambered allows
the steam to be supplied to the condenser at the desired height above the bottom
thereof, to insure a column or body of condense water in the condenser of the
requisite height, and further, the nut enables the steam pipe to be blown out and
cleansed when necessary. In the opposite side of the condenser is formed a chamber
Q having an opening m through the same which is governed by a screw valve n,
the latter serving to regulate the amount of water to be admitted to the interior of
chamber Q from the main chamber of the condenser. Rising from the bottom of
chamber Q a vertical partition o which extends nearly to the top of said chamber,
the partition preventing a direct communication between the condenser and oil
receptacle, and insuring a column of water within the chamber equal in height to
that of partition o. To the bottom of chamber Q is attached a feed water pipe R
which extends downwardly any desired distance into the oil receptacle, and then
by a return bend is carried upwardly and is inserted in the upper end of the glass
tube H.
A steam pipe S is screwed upon the screw threaded stem K of the condensing
chamber, and extends through the frame work of the cab, through the shell of the
steam dome, and is screwed into the side of the dry pipe. To provide for the con-
traction and expansion of steam pipe S the shell of the dome is furnished with a
sleeve T, which is firmly secured to the dome and serves as a passage for steam
pipe S. Sleeve T is provided with a follower or packing cap p which insures a
tight joint between the sleeve and steam pipe. By means of this construction the
steam may have an endwise movement, due to its expansion and contraction, without
affecting the shell of the steam dome, and without opening any joint or seam between
the shell of the dome and the steam pipe. Within the steam pipe S is placed an
oil feed pipe N, one end of which projects into the dry pipe, while its opposite
end is screwed into the oil passage M in the condenser. The operation of the
improved lubricating apparatus is as follows:-Steam enters the steam pipe S from.
the dry pipe and flows through the vertical steam pipe in the condenser to the main
chamber, where it is condensed. The condense water is fed to the chamber Q in any
desired quantity, and from thence flows downwardly within the return bend pipe
to the upper end of the glass indicating tube. The return bend pipe serves a double
function, viz., it conducts the warm condense water through the lubricating material,
thus keeping the latter at the proper temperature to retain it in a limped condition
under all degrees of temperature. Again, the return bend pipe forms a trap which
is always filled with condense water, and serves as an effectual water seal to prevent
As the water issues from the end of the return
any flow of oil into the condenser.
bend pipe it falls into the glass tube in drops. As the oil stands at the same height
in the glass tube that it does in the main oil receptacle of the lubricator the drops
of water fall the length of the glass tube and pass out into the lower end of the oil
receptacle. The drops of condense water entering the oil receptacle operate to
displace an equal quantity of oil, and cause the latter to raise the check valve and
flow through the oil feeding pipe into the dry pipe, and there mingle with the steam
passing to the valve chest and cylinders of the locomotive. The engineer can thus
readily ascertain the amount of oil being fed to the engines by inspecting the glass
tube of the lubricator and ascertaining the number of drops of water falling through
the tube in any given time, and the amount of oil to be fed can be easily regulated
by varying the admission of condense water by changing the opening of the feed
valve. When the oil receptacle has become filled with water it may be emptied by
opening the waste cock, allowing the water to escape, and the oil receptacle again
filled. The construction of the oil receptacle with the glass indicating tube seated
inside the periphery of the same is an important feature of the improvement, in

page_text: that the glass tube is thoroughly protected, and hence not easily broken or displaced,
and further, the apparatus is rendered more compact and efficient by reason of such
an arrangement of parts. The oil is fed directly to the steam in the dry pipe, and
hence is conducted to both valves and cylinders of the locomotive. This enables
the engineer to govern the flow of lubricants to both engines by a supply of
lubricant contained in a single lubricating apparatus. The connection between the
lubricator and the dry-pipe being formed by a slip joint allows of the expansion
and contraction of the steam pipe without affecting any of the steam-joints or the
lubricator proper. Fig. 4 illustrates the form of connection when it is desired to
place the lubricator at one side of the cab. In this construction the curved elbows
V, V, are employed to constitute the steam pipe, and the oil feeding pipe is properly
curved to fit within the steam pipe. In Figs. 5 and 6 is represented another con-
struction of coupling devices for connecting the dry pipe and lubricator. In Fig. 5
the stem or extension of the lubricator is provided with a socket within which is
inserted a coupling nut s, which is screw threaded at s¹ and engages with the steam
pipe S. Coupling nuts is secured to the stem of the lubricator by means of a
coupling nuts having an inwardly projecting flange 8³, said coupling nut & being
screw threaded to engage with the stem of the lubricator. Theso means afford a
complete and effective coupling device for the parts, and always insure a tight joint.
When the steam and oil pipes are to be bent to locate the lubricator in the desired
position the oil pipe T is made in sections and connected by elbow joints t, whereby
it is not necessary to form bends in the oil pipe. The coupling in Fig. 6 is the same
as that shown in Fig. 5; the only difference between the two devices is that a
straight oil pipe is used, and hence elbow pipes are not necessary.
