PROVISIONAL SPECIFICATION.
Improvements in Lubricators, More Especially Applicable to the
Parts of Engines and Machines which have a Reciprocating
Motion.
I, ERNEST BALDWIN of Loughborough in the county of Leicester, Engineer (a
communication from abroad by Daniel McGill of the City of Wellington in the Colony
of New Zealand, Locomotive Engine Driver) do hereby declare the nature of this
invention to be as follows:-
My Invention relates to Improvements in Lubricators and has for its objects
lubricating the parts of engines and machines having a reciprocating motion whereby
the usual fibrous nicks are dispensed with, and the supply of oil accurately applied
with less loss than heretofore.
These objects I accomplish by fastening on or forming at or near the part to be
lubricated a cup or vessel to contain the oil, such cup or vessel having a cap which
can be easily removed for examination and cleaning and which cap has a hole in it
for the supply of oil closed by a cork or stopper.
In the interior of this cup and screwed into the bottom of the said cup is a smaller
cup or chamber which is air tight and has a small hole in the bottom communicating
by a duct direct to the pin or bearing to be lubricated, which duct is stopped at its
upper end by a ball valvo. Into the side of the outer cup I insert a regulating set
screw and locked nut, the end of which is tapered and fits into a supply hole in the
inner cup to regulate the supply of oil from the outer to the inner cup in the exact
quantity found by experiment to be necessary for proper lubrication.
The seat in which the ball valve rests on the oil delivery pipe is so formed that
(when the machine is at rest) it completely covers the pipe leading from the inner
chamber to the pin or bearing to be lubricated and is only moved therefrom by each
stroke of the machine; thus completely preventing the passage of any oil from the
inner chamber whilst the machine is at rest.
Dated this 29th day of June 1888.

COMPLETE SPECIFICATION.

1, ERNEST SMITH BALDWIN, of the town of Loughborough, in the County of
Leicester, Engineer, (a communication to me from abroad from Daniel McGill, Engine
Driver, of the town of Wellington in the colony of New Zealand) do hereby declare
the nature of this invention and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement :-
My Invention relates to improvements in Lubricators and has for its object lubricating
the parts of Engines and Machines having a reciprocating motion whereby the
usual fibrous wicks are dispensed with and the supply of oil accurately applied with
less loss of lubricant than heretofore.
In order that my invention may be most easily understood I will now proceed to
describe the same and for that purpose shall refer to the accompanying drawing in
which

() is a caso for the spring (j).
The action of the apparatus is as follows:-
The spout of the oil-can or other feeder being applied to depress the ball (i) the
oil enters the chamber (a. a.) through the passages (16) partially filling the said
chamber. At the lower end of the chamber (a. a.) is formed a chamber (c) made,
preferably, of a circular form and covered by the air tight cap (e). The chamber (e)
communicates with the chamber (a. a.) by means of the passage (h), which passage
is regulated by the set screw (9). The oil entering by the passage (4) partially
compresses the air in the chamber (e) and this, together with the oscillation of the
all by the reciprocating netion of the machine allows only a small quantity of
oil to pass down the passage (d) and the supply is further regulated by the screw (g).
When the machine is at rest leakage from the cup and passages is absolutely
prevented thus producing great economy.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declaro that what I
claim is :-
In a lubricator for the reciprocating parts of Engines and Machines the combination
of a ball valve with an air tight chamber and regulating screw so that the oil may bo
more accurately and economically applied than heretofore, substantially as herein-
before described and illustrated in the accompanying drawing.
