in the County of Lancaster, Engineers, &c., for the Invention of "IM-
PROVEMENTS IN LUBRICATORS POR INTRODUCING LUBRICATING MATTER INTO
STEAM CYLINDERS, AND OTHER CHAMBERS OR PARTS UNDER PRESSURE."
Sealed the 24th May 1859, and dated the 26th November 1858.
PROVISIONAL SPECIFICATION left by the said Price Griffiths and John
Brennand at the Office of the Commissioners of Patents, with their
Petition, on the 26th November 1858.
We, PRICE GRIFFITHS and JOHN BRENNAND, both of Burnley, in the County
of Lancaster, Engineers, &c., do hereby declare the nature of the said Inven-
tion for "IMPROVEMENTS IN LUBRICATORS FOR INTRODUCING LUBRICATING MATTER
INTO STEAM CYLINDERS AND OTHER CHAMBERS OR PARTS UNDER PRESSURE," to be
as follows:-
Our Invention relates to improvements in lubricators applicable for the
introduction of oil or other lubricating matter into steam cylinders.or other.

works; F is the compartment into which the lubricating matter first enters

furnished with a cover I screwed therein, and having a depending projection,
which prevents the valve rising too high out of its seat; D is the compartment
into which the lubricating matter is first forced by the plunger M, which
compartment is fitted with a valve K at the top to prevent the oil returning
again into F; it is further furnished with a cover H, as also the compartment
E with cover G; R is the passage between E & F, and T the passage between
E & D, while V is the delivery passage, conducting the oil or lubricating
matter to where it is required; S & W are holes drilled for the purpose of
drilling the passages R & T; these holes are stopped with screw plugs, which
may be withdrawn if required to clean the passages R, T; Q is a space for
the introduction of packing, which may be screwed up by the screw P. The
plunger or ram M has motion communicated to it by any suitable power, such
as from the valve shaft of a steam engine or any other moving part.
The parts being so disposed, and the chamber B filled with lubricating
matter, the descending motion of M creates a partial vacuum in its chamber
and above valve L, causing the oil to enter thereat; on the ascending motion of
M taking place, the oil entering E is forced through passage T, through valve
K, and out at the delivering pipe V. The same action being repeated at each
stroke of the pump. The pipe V being placed in communication with the steam
cylinder or any other chamber or place into which it is required to be forced,
the lubricating matter is conducted and enters thereby.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Price Griffiths and John Brennand in the Great Seal Patent
Office on the 26th May 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, PRICE
GRIFFITHS and JOHN BRENNAND, both of Burnley, in the County of Lancaster,
Engineers, &c., send greeting..
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-sixth day of November, in the year of our
Lord One thousand eight hundred and fifty-eight, in the twenty-second year
of Her reign, did, for Herself, Her heirs and successors, give and grant unto
us, the said Price Griffiths and John Brennand, Her special licence that we,
the said. Price Griffiths and John Brennand, our executors, administrators,

page_text: and assigns, or such others as we, the said Price Griffiths and John Brennand,
our 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 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 FOR INTRODUCING LUBRICATING MATTER INTO STEAM CYLINDERS AND
OTHER CHAMBERS OR PARTS UNDER PRESSURE," upon the condition (amongst others)
that we, the said Price Griffiths and John Brennand, our executors or adminis-
trators, by an instrument in writing under our, 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 we, the said Price Griffiths and John Brennand, do
hereby declare the nature of our said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained in and
by the following statement, reference being had to the Drawings hereunto
annexed, and to the letters and figures marked thereon (that is to say) :-
Our Invention relates to improvements in lubricators applicable for the
introduction of oil or other lubricating matter into steam cylinders or other
chambers or places where pressure exists.
Fig. 1 of the annexed Drawings represents an external view, and Fig. 2 a
vertical section of a lubricator, arranged and constructed according to our
Invention; Fig. 3 is a plan of the same with the cover A removed, while
Figs. 4, 5, 6, 7, and 8 represent the internal fittings detached; B is the cup
or body of the lubricator forming the capacity containing the lubricating
matter. In this apparatus a force pump is used which is fixed within the cup
B; this pump, which is represented separately at Figs. 4 and 5 (Fig. 5 being
a section thereof) is divided into three compartments E, F, and D; E is the
compartment in which the plunger M works; F is the compartment into
which the lubricating matter first enters through the valve L, fitted at the
bottom thereof. The compartment F is furnished with a cover I screwed into
it, and having a depending projection which prevents the valve L rising too
high out of its seat; D is the compartment into which the lubricating matter
is first forced by the plunger M, which compartment is fitted with a valve K
at the top to prevent the oil returning again into F; it is further furnished with
a cover H, as also the compartment E with cover G; R is the passage between
E and F, and T, the passage between. E and D, while V is the delivery

page_text: passage, conducting the oil or lubricating matter to where it is required. S &
Ware holes drilled for the purpose of drilling the passages R & T; these holes
are stopped by screw plugs, which may be withdrawn if required to clear the
passages R&T; Q is a space for the introduction of packing, which may be
screwed up by the screw P, in order to render the working of the plunger M
fluid-tight.
The plunger or ram M has motion communicated to it by any suitable
power, such as from the valve shaft of a steam engine, or it may be any other
moving part. The parts being so disposed and the chamber B filled with
lubricating matter, the descending of plunger M creates a partial vacuum in its
chamber E and above valve L, causing the oil to enter thereat. On the ascending
motion of M taking place, the oil or other lubricating matter entering E is
forced through passage T, through valve K, and out at the delivery pipe V. The
same action being repeated at each stroke of the pump, so long as the supply
of the reservoir or cup B is maintained.
The pipe V being placed in communication with the steam cylinder or any
other chamber or place into which the oil or other lubricating matter is
required to be forced, it is conducted thereto and forced to enter by the action
of the apparatus described.
Having described the nature of our Invention, and the manner of performing
the same, we declare that what we claim as our Invention, to be protected by
the herein-before in part recited Letters Patent, is the arrangement and con-
struction of parts constituting the lubricating apparatus herein-before described,
and its application to lubrication purposes, as herein-before set forth.
In witness whereof, I, the said Price Griffiths, on behalf of myself
and the said John Brennand, have hereunto set my hand and seal,
this Twenty-third day of May, in the year of our Lord One thousand
eight hundred and fifty-nine.
