Worcester, Engineer, for the Invention of "IMPROVEMENTS IN LUBRI-
CATORS:"
Sealed the 28th December 1866, and dated the 26th October 1866.
PROVISIONAL SPECIFICATION left by the said John Storer at the
Office of the Commissioners of Patents, with his Petition, on the
26th October 1866.
I, JOHN STORER, of Dudley, in the County of Worcester, Engineer, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
LUBRICATORS," to be as follows:-
My said Invention consists in constructing and arranging the parts of a
lubricator in the following manner :-I make the cup or reservoir for con-
taining the lubricating material of a cylindrical figure by preference; the
said cup or reservoir is supported on a hollow stem having a valve or stop-
cock to regulate the quantity of the lubricating material passing out of the
cup or reservoir. Around the upper part of the outside of the cup or reservoir
is a flange, and underneath the said flange is a groove; portions of the said
flange are cut away at two opposite points, each cut-away portion extending
about one quarter round the cup. or reservoir. The lid or cover which closes-
"

page_text: the top of the cup or reservoir has in its inside and near its lower edge a rim
or flange, which flange has portions cut away at opposite points so as to leave
two projections opposite to each other. The lid is placed upon the cup or
reservoir in such a position that the said two projecting pieces enter the cut-
away parts of the flange on the top of the cup or reservoir, and by turning
the lid the said projecting pieces engage underneath the said flange, and fix
down the lid; by turning the lid in the opposite direction it may be removed
from the cup or reservoir. The range of motion of the lid is limited by a stop ;.
through the top of the lid a screw passes; the said screw carries at its top
a hand wheel or handle for turning it, and carries at its bottom an inner
cap or lid which is capable of being screwed down air and steam tight on the
shoulder forming the top of the cup or reservoir; this lid is made of hard
metal, and its rim bears on a ring of soft metal let into the top of the cup or
reservoir. Over the passage at the bottom of the cup or reservoir is a per-
forated hollow cylinder or cage, through which the lubricating material has
to pass, and which prevents the choking of the hollow stem, and retains any
solid matters which may be contained in the lubricating material.
Lubricators made according to my Invention are especially suited for the
use of suet, tallow, or other lubricating. materials which require warmth to
liquify them, and are especially applicable to the cylinders of steam.engines
and to large shafts, but-are also applicable to. all purposes where lubricators
are required.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Storer in the Great Seal Patent.Office.on the
17th April 1867.

said John Storer, my executors, administrators, and assigns, should at
any time agree with, and no others, from time to time and at all times
thereafter during the term therein expressed, should and lawfully might

page_text: make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Invention
for "IMPROVEMENTS IN LUBRICATORS," upon the condition (amongst others)
that I, the said John. Storer, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and seals,
should particularly describe and ascertain the nature of the said Invention,
'and in what manner the same was to be performed, and cause the same to
be filed in the Great Seal Patent Office within six calendar months next
and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said John Storer, do hereby declare
the nature of the said, Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement thereof, that is to say:-
My said Invention consists in constructing and arranging the parts of a
lubricator in the following manner:-I make the cup or reservoir for
containing the lubricating material of a cylindrical figure by preference; the
said cup or reservoir is supported on a hollow stem having a valve or stop-cock
to regulate the quantity of the lubricating material passing out of the cup or
reservoir. Around the upper part of the outside of the cup or reservoir is a
flange, and underneath the said flange is a groove. Portions of the said
flange are cut away at two opposite points, each cut-away portion extending:
about one quarter round the cup or reservoir. The lid or cover which closes
the top of the cup or reservoir has in its inside and near its lower edge a rin
or flange, which flange has portions cut away at opposite points, so as to leave
two projections opposite to each other. The lid. is placed upon the cup or
reservoir in such a position that the said two projecting pieces enter the
cut-away parts of the flange on the top of the cup or reservoir, and by turning
the lid the said projecting pieces engage underneath the said flange and fix.
down the lid. By turning the lid in the opposite direction it may be removed
from the cup or reservoir. The range of motion of the lid is limited by a
stop; through the top of the lid a screw passes; the said screw carries at its
top a hand wheel or handle for turning it, and carries at its bottom an inner
cap or lid, which is capable of being screwed down air and steam tight on the
shoulder forming the top of the cup or reservoir. This lid is made of hard
metal, and its rim bears on a ring of soft metal let into the top of the cup or
reservoir; over the passage at the bottom of the cup or reservoir is a
perforated hollow cylinder or cage through which the lubricating material has
to pass, and which prevents the choking of the hollow stem, and retains any
-solid matters which may be contained in the lubricating material..

Lubricators made according to my Invention are especially suited for the
use of suet, tallow, or other lubricating materials which require warmth to
liquify them, and are especially applicable to the cylinders of steam engines
and to large shafts, but are also applicable to all purposes where lubricators
are required.
Having explained the nature of my Invention, I will proceed to describe,
with reference to the accompanying Drawing, the manner in which the same
is to be performed.
Figure 1 represents a vertical section of a lubricator constructed according
to my Invention; Figure 2 is a plan of the under side of the cover of the
same; and Figure 3 is a plan of the cup or reservoir of the lubricator, the
cover being removed. The same letters of reference indicate the same parts
in each Figure of the Drawing.
a is the cylindrical cup or reservoir of the lubricator containing the suet,
tallow, or other lubricating material. The said cup or reservoir is attached
by the hollow stem or pipe 6 to the steam cylinder or other part of the
engine or other machine or apparatus to be lubricated. In the said hollow
stem 6 is a valve or stop-cock c worked by the handled for regulating the
quantity of lubricating material passing out of the cup or reservoir a. e is
the lid or cover of the reservoir, capable of ready attachment and removal.
Around the upper part of the reservoir a is a flange f, and underneath the
said flange is a groove g. Portions of the flange f are cut away at two
opposite points, each cut-away part extending about one quarter round the
cup or reservoir. These cut-away parts are represented in Figure 3, and are
marked h, the groove g being indicated in dotted lines in the said Figure 3.
The closing lid or cover e of the cup or reservoir a has on its inside and near
the lower edge a rim or flange i, which flange has portions cut away at
opposite points so as to leave two projections opposite each other, as
represented in Figure 2, where the cut-away parts of the flange i are
marked. The projections i of the rim of the cover e are of a size proper
to enter the cut-away parts h, h, of the top of the cup or reservoir a. In
order to fix the lid or cover e to the cup or reservoir a the said lid or cover is
placed in such a position that its projecting parts i, i, are opposite the
cut-away portions h, h, of the top of the reservoir. By then depressing or
lowering the lid or cover e the projections i, i, enter the groove g in the top
of the reservoir, and by turning the lid or cover through a partial rotation
the projections i, i, engage under the flange f,f, of the reservoir, and thereby
attach the lid or cover to the reservoir. The range of motion of the lid or
cover e is limited by a stop at m (see Figure 3) in the groove 9 in the top of

page_text: the reservoir.
When it is wished to remove the lid or cover e it is turned so
as to bring its projections i, i, opposite the cut-away parts h, h, of the flange f,
when the said projections i, i, can be lifted from the groove 9 through the
cut-away parts h, h, and the lid or cover removed from the reservoir. The
lid or cover e is made air and steam tight in the following manner :-Through
the top of the lid or cover e a screw n passes, the said screw working in a
concave or hollow screw in the said top. The said screw n carries at its top
a hand wheel or handle o for working it, and carries at its bottom an inner
cap or lid p, which cap or lid p by turning the screw n can be pressed down
air and steam tight on the shoulder forming the top of the cup or reservoir a,
as represented in Figure 1. Let into the top shoulder of the reservoir is a
ring or seat of soft metal q upon which the rim p* of the inner cap or lid p
bears when the latter is screwed home, and thereby forms a perfect air and
steam-tight joint between the said parts. The bottom of the screw n is
connected to the inner cap or lid p by means of a pin r passed through the
said cap or lid, and entering an annular groove s made at the said bottom of
the screw. By this means the inner cap or lid p is removed and replaced
with the outer lid or cover e while still permitting the screw n to rotate freely
in the lid p so as to advance it against or withdraw it from its soft metal seat
at the top of the shoulder of the reservoir. To remove the outer lid or
cover and air and steam tight inner cap p, p, a backward partial rotation is
given to the screw n by its hand wheel for the purpose of loosening or
removing the inner cap p, p, from its seat q. The outer lid or cover e is
then turned till its projections i, i, come opposite the openings h, h, in the
top flange f of the reservoir, when the lid or cover e with its inner cap p, p³,
screw n, and hand wheel o may be lifted from the top of the reservoir.
replacing the lid or cover e the projections i, i, are first dropped into the
groove g, and afterwards engaged under the flange ƒ of the reservoir, and by
then giving a partial rotation to the screw n the inner cap p is brought down
and held firmly to its seat, and the top of the reservoir thereby securely
closed.
On
By constructing and arranging the lids or covers of lubricators in the
manner described and represented their removal and replacement are effected
with great ease, and in less time than with lids or covers of the ordinary
construction, and a very efficient air and steam tight joint is also produced.
Over the passage at the bottom of the cup or reservoir a is a perforated
hollow cylinder or cage t, through which the lubricating material has to pass,
and which prevents the choking of the hollow stem 6 and retains any solid
matters which may be contained in the lubricating material. The perforated

page_text: cylinder or cage t may be covered with cloth or other fibrous material so as
to form a strainer for the lubricating material, and for retarding its passage
to the outlet pipe b. When suet is employed as the lubricant I prefer to
enclose it in a bag made of canvas or other woven fabric.
Having now described the nature of my Invention, and the manner in
which the same is to be performed, I wish it to be understood that I do not
limit myself to the precise details herein described and represented, as the
same may be varied without departing from the nature of my Invention ; but
I claim as my Invention the improvements in lubricators herein-before
described and represented in the accompanying Drawing, that is to say, the
construction and arrangement of parts substantially as described and illustrated
for effecting the rapid and secure attachment of the lid or cover to and its
removal from the cup or reservoir of the lubricator.
Also the inner cap or lid, constructed and worked substantially as described
and illustrated in combination with a soft metal seat for the purpose of
forming an air and steam tight joint between the said inner cap or lid and
the top of the cup or reservoir of the lubricator.
In witness whereof, I, the said John Storer, have hereunto set my
hand and seal, this Sixteenth day of April, in the year of our Lord.
One thousand eight hundred and sixty-seven.
