PROVISIONAL SPECIFICATION.
An Improved Lubricator for Locomotive or other Engines.
We FRED GLOSSOP of 252 Petre Street Sheffield in the County of York
Turner and Fitter, and JOHN ALBERT TINKER of 131 Ellesmere Road Sheffield
Engineer's Clerk do hereby declare the nature of this invention to be as
follows:-
The object of our invention is to save the labour and avoid the danger of having
to get under, say, a locomotive engine to unscrew and fill the engine lubricators as
at present, the lubricators made according to our invention being readily filled
from the foot plate and in much less time than according to the existing system.
Our improved lubricator, which is made of brass or of other suitable metal, has
a receptacle of the ordinary kind for holding and storing the lubricating oil,
having at its base the usual outlet to the engine's mechanism requiring to be
lubricated.
At its top the lubricator is covered with a lid or cover which is screw-
threaded for screwing into or off the oil chamber. In this lid or cover suitable
holes are made so that the oil can be poured freely into the oil receptacle or
chamber.
Inside this oil receptacle we place a circular or other suitably shaped casting
which near its top is made something of a mushroom form above which there is a
rim formed on the casting, and the lid or cover is screwed down tightly on to the
top of the rim so as to hold the casting firm in its place. The rim has a
sufficient number of holes pierced in it to allow the oil to pass through on to
the top of the mushroom shaped part the edge of which is made with suitable
grooves or recesses so as to allow the oil to flow down into the oil receptacle
or holder.
At its bottom end the casting is made tubular for a short distance, its exterior
being formed like an inverted cone above which a hole is made in the tube, being
provided so as to allow of only a regular quantity of oil dropping through the
bottom end of the tube into or onto the bearings of the engine mechanism.
In using our lubricator it is not necessary to unscrew the top for refilling as the
oil on being poured into the inlet in the lid will flow freely over the sloping surface
of the mushroom portion of the casting into the oil receptacle below, and when the
lubricator is filled the oil cannot be thrown out again by the motion of the engine
because it would have the mushroom portion to pass the bottom surface of which is
flat, and the rim above the mushroom part prevents the backward escape of the oil
the inside of the lid or cover on its under surface being so formed as to return the
oil thrown up to it thereby preventing any from being thrown out.
It is well known that oil does escape from the air hole, or holes, of the
lubricators now in use, but no escape of oil is possible from the air or inlet hole of
our lubricator.

An Improved Lubricator for Locomotive or other Engines.
We FRED GLOSSOP of 252 Petre Street Sheffield in the County of York
Turner and Fitter and JOIN ALBERT TINKER of 131 Ellesmere Road Sheffield
Engineer's Clerk 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 in writing, and on reference to the accompanying
sheet of drawings :—
The object of our invention is to save the labour and avoid the danger of having
to get under, say, a locomotive engine, to unscrew and fill the engine lubricators as
at present, as the lubricators made according to our invention can be readily filled
from the foot plate and in much less time than according to the existing system.
In order that our said invention may be fully understood we have illustrated it
on the accompanying sheet of drawings which will be found marked with figures
and letters of reference corresponding with those in the following description, like
letters of reference indicating the same parts of the lubricator in all the figures.
Figure 1 is a section taken through the centre of the lubricator to show its
internal construction.
Figure 2 is an elevation of the mushroom-shaped portion of the apparatus.
Figure 3 is an elevation of the lid or cover of the lubricator.
Figure 4 is a plan of the same; and
Figure 5 is a plan of Figure 2.
Our improved lubricator, which is made of brass or of other suitable metal, has
a receptacle m, of the ordinary kind, for holding and storing the lubricating oil
having at its base the usual outlet p, to the engine mechanism requiring to be
lubricated. At its top the lubricator is covered with a lid or cover h, which is
screwthreaded as shown at 1, for screwing into or out of the oil chamber or
receptacle m; in this lid or cover suitable holes j, are made so that the oil can
be poured into the recess i, in the lid or cover and will pass, through the holes j,
freely down to the oil chamber or receptacle m.
Inside the oil receptacle we place a circular or other suitably shaped casting (see
Figures 1 and 2) which near its top is made somewhat of a mushroom form as at d,
above which is a rim e, formed on the casting and the lid or cover h, is screwed
down tightly onto the top of the rim so as to hold the casting firm in its place.
The rim e, has a sufficient number of holes f, pierced in it to allow the oil to pass
through onto the top of the mushroom-shaped part d, the edge of which is made
with suitable grooves or recesses as at g, so as to allow the oil to flow down into
the oil receptacle or holder m.
The casting below the mushroom-shaped part d, is made in the form of a
spindle a, the bottom end of which is tubular for a short distance its exterior
being formed like an inverted cone as seen in Figures 1 and 2, above which a hole
is, or small holes b, are, made in the tube being provided so as to allow of only a
regular quantity of oil dropping through the bottom end of the tube into or onto
the bearings of the engine mechanism. The spindle a, may or may not be encircled
by a gauze cylinder as may be found necessary.
The lid or cover h, of the lubricator is made hexagonal at its top so that a
spanner can be fitted onto it to tightly screw down the lid or cover onto the oil
receptacle or holder m. k, is a flange surrounding the lid or cover h, and it has a
milled edge so that the lid or cover may be screwed down by hand if desired.
o, is a screwthread made on the bottom extremity of the lubricator by which it
can be screwed into the engine mechanism requiring to be lubricated.
In using our lubricator it is not necessary to unscrew the top for refilling as the
oil on being poured into the inlet or recess i, in the lid or cover will flow down to
and over the sloping surface d, of the mushroom-shaped portion of the casting and

page_text: thence into the oil receptacle below, and when the lubricator has been filled the oil
cannot be thrown out again by the motion of the engine because it would have the
mushroom-shaped portion to pass, the underneath surface of which is either flat, or
as shown at d', in Figure 1 of the drawings it is made of a concave form which we
find will more effectually answer the purpose of returning the oil down into the oil
receptacle or chamber; and the rim e, above the mushroom-shaped part prevents
the backward, that is, the upward escape of the oil, the inside of the lid or
cover h, on its under surface being (as shown in Figure 1,) so curved or formed
that the oil which might be thrown up to it by the motion of the engine is at once
returned down into the oil receptacle thereby preventing any oil from being thrown
out of the lubricator and wasted.
It is well known that oil does escape from the air hole, or holes, of the lubricators
now in use but no escape of oil is possible from the air or inlet hole i, of our
lubricator.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
1. The new and peculiar construction, combination, and arrangement of mechanism
in its entirety constituting an improved and safety lubricator, and its application
to and use for lubricating locomotive or other engines, substantially as hereinbefore
described and as illustrated on the accompanying sheet of explanatory drawings.
2. The specially formed casting as illustrated in Figures 1, 2 and 5 of the
drawings, consisting of a mushroom-shaped part d, d', a rim e, and a spindle a,
with its tubular cone-shaped lower extremity perforated with a hole or holes for
allowing a regular supply of oil passing through the same and into or onto the
engine mechanism, substantially as hereinbefore specified.
3. The so curving or forming the under inside surface of the lid or cover h, that
any oil that might possibly be thrown up to it by the motion of the engine is at
once returned down into the oil receptacle or holder thereby preventing any oil
from being thrown out of the lubricator and wasted.
