Improvements in Lubricating Apparatus.
We, EDWIN DUNBAR BANGS, Inventor and Manufacturer, of No. 1522, Cedar
Street, Milwaukee, in the County of Milwaukee and State of Wisconsin, United
States of America, and CARROLL A. PIPER, Manufacturer of No. 162, Washington
Street, in the City of New York (Flushing, Borough of Queens), in the County
of Queens and State of New York, United States of America, do hereby declare
the nature of our invention, and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement:
-
The object of our invention is to provide a simple and economic lubricating
device especially adapted for supplying lubricating material continuously and
regularly to the bearings or journals of locomotive and marine engines, and to
employ air pressure to effect such feed. Another object of the invention is to
provide a nozzle for the introduction of oil into the feed pipes, or the exit of oil
therefrom, which will be so constructed that any foreign matter in the lubricat-
ing material will not tend to clog the pipes.
The invention consists in the novel construction and combination of the several
parts, as will be hereinafter fully set forth and pointed out in the claims.
Reference is to be had to the accompanying drawings forming a part of this
specification, in which similar characters of reference indicate corresponding
parts in all the figures.
Figure 1 is a rear elevation of a locomotive cab and a vertical section through
the main frame of the engine, illustrating the invention in front elevation and as
applied to the boiler;
Figure 2 is a plan view of a portion of the main frame of a locomotive, show-
ing the manner in which the lubricating material is directed to the bearings;
Figure 3 is an enlarged front elevation of the improved device, parts thereof
being in section ;
Figure 4 is an enlarged view of a drip pipe and the coupling for said pipe
attaching to it the lubricating supply pipe, a portion of the drip pipe being in
section and likewise a portion of the coupling;
Figure 5 is a plan view of the nozzle used in connection with the inlet end of
the lubricating supply pipe; and
Figure 6 is a side elevation of a nozzle adapted to be located at the delivery end
of the drip pipe.
A represents the rear end of a locomotive boiler, and B bearings for the axle of
a truck C. D represents the engineer's valve and D₁ the pipe from the air-pres-
sure reservoir leading to said valve; D2 represents the air vent for the said
engineer's valve, all of which parts may be of ordinary construction.
E represents a tank of any desired shape or of any suitable size adapted to
contain lubricating material. Said tank is provided with a faucet 10 at its lower
end whereby its contents may be removed, and the tank is further provided with a
gauge glass 11 at the front, whereby the level of the lubricating
material in the tank may be readily discerned. The lubricating material is fed
into the tank E through the medium of a cup 12 connected with the top portion

page_text: of the tank, a suitable valve 13 intervening the said cup and tank, and a pet-
cock 14 is also located at the upper portion of the tank to permit the escape of
air when the tank is to be supplied with a lubricating material. A gauge 15
is also connected with the upper portion of the tank, adapted to indicate the
amount of air pressure in the tank E, the air being delivered into the top por-
tion of the tank above the level of the lubricating material through the medium
of a pipe 16 that connects with the pipe I) from the engineer's valve, as shown
in Figure 1, the said air-supply pipe 16 having a valve 17 suitably placed between
its ends.
An outlet pipe 18 is usually connected with each side of the tank E at or near
its bottom. These outlet pipes 18 are shown as of elbow shape and are made
tapering, their inner ends being of less diameter than their outlet ends. In con-
nection with each outlet pipe 18 at its outlet end a nozzle 19 is employed, said
nozzle being in the form of a plug having an exteriorly threaded surface whereby
it may be screwed into the outlet portion of the oulet pipe. Each nozzle 19 is
made tapering or conical at its inner end and is provided with a tapering bore 21,
commencing at the apex of the conical section of the nozzle and extending within
the nozzle to an engagement with an enlarged opening 22, which constitutes a
continuation of the tapering bore 21. The tapering bore 21 of a nozzle is of least
diameter at the apex of the. conical surface of the nozzle, as is clearly shown in
Figure 3.
Any suitable form of coupling 24 is adapted to connect the outlet end of the
outlet pipe 18 with a lubricating supply pipe 23; and the lubricating supply
ripe or pipés may be carried over any bearing or box that is to be lubricated, as
shown in Figure 2. Each nozzle 19, as shown in Figures 3 and 5, is provided
with a polygonal upper extension 19" through which the enlarged opening 22
is continued, and which said extension 19" enables the nozzle to be manipulated
by a wrench or a like tool.
Wherever a bearing or box B is to be lubricated, the supply pipe 23 is provided
preferably with a T-fitting 24, as shown in Figures 2 and 4; and a drip pipe 25
is coupled in any suitable or approved manner at 26 with one member of the
T-fitting, the delivery end of the drip pipe being adapted to extend over the oil-
receiving opening of, or a cup connected with, the bearing or journal to be
lubricated.
Each drip pipe 25 is provided at its delivery end with a nozzle 27, and each of
said nozzles consists of an upper reduced and exteriorly threaded section 28, the
upper end whereof is conical, and a base section 29 of greater diameter than the
upper section 28, and when the upper section 28 is screwed into the drip pipe,
the delivery end of the drip pipe will engage with the upper edge of the lower
section 29 of the nozzle, as shown in Figure 4. The reduced section 28 of a
nozzle 27 is provided with a tapering bore 30 that extends from the apex of said
section into the larger and lower section 29, said bore 30 being of greatest
diameter at its lower end; and said bore 30 connects with a chamber 31 in the
bottom of the base section of the nozzle, which chamber is of greater diameter or
cross sectional area than the diameter or cross sectional area of the outer end of
the tapering bore 30.
It will be observed that when nozzles are employed constructed as described,
the conical portions of the nozzles face the direction of supply, and that if any
foreign matter be contained in the lubricating material, said foreign matter will
be deflected to either side of the nozzle, leaving the bore of the nozzle free; and
that if any particle of such foreign matter should be able to enter the contracted
end of the nozzle bore, said foreign matter will be forced through the nozzle into
the enlarged portion of the bore and from thence outward, thus insuring a con-
tinuous and regular supply of lubricating material to any bearing or journal,
where the nozzles at the end of the drip pipes, or other equivalent pipes, may
be directed.
I desire it to be understood that any number of drip pipes may be connected

page_text: with a supply pipe, and that each drip pipe employed may have the same
restricted outlet; thus the amount of material dispensed by each drip pipe is the
same no matter what relation the drip pipe may sustain to the source of supply.
Having thus particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:
-
1. In connection with lubricant-conveying pipes, a plug located at the delivery
end thereof and having a conical end extending toward the source of supply and a
bore reduced in direction of the conical end.
2. In connection with lubricant-conveying pipes, arranging a plug such as is
specified in Claim 1, at the delivery end of a supply nozzle contracted toward the
supply extremity, substantially as described.
