A TYPOWEMENT IN STEAM ENGINE LUBRICATORS.
Year: 1872

page_text: LETTERS PATENT to Robert Sutcliffe, of Castle Mills, Idle, near
Leeds, in the County of York, Cotton' Doubler, for the Invention
• A TYPOWEMENT IN STEAM ENGINE LUBRICATORS.
of "AN IMPROVEMENT IN STEAM ENGINE LUBRICATORS.
I, ROBERT SUTCLIFFE, of Castle Mills, Idle, near Leeds, in the County
of York, Cotton Doubler, do hereby declare the nature of the said
Invention for "AN IMPROVEMENT IN STEAM ENGINE LUBRICATORS," to be as
follows:-
This Invention relates to the apparatus employed for the admission or
the passing of tallow into the cylinder or cylinders of steam engines for
lubricating the piston or pistons thereof, and my improvement consists
in the application to the ordinary apparatus of an additional chamber and
tap. The apparatus as heretofore constructed consists of a chamber

page_text: with a tap on each side, one as inlet from the tallow cup and the other
as inlet from the cylinder. In practice it is found that where high
pressure steam is used the taps are soon rendered leaky and deficient,
however well fitted, and so the apparatus becomes inoperative. Now I
find that by the addition of another chamber or chambers, and taps
betwixt the cup and the cylinder, the evil is remedied, because the
action or pressure of the steam is distributed; that is to say, one tap
serves to protect the other, and so by distribution of wear and tear
lubricators so constructed are rendered effective and serviceable.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Robert Sutcliffe in the Great Seal Patent Office
on the 5th September 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROBERT
SUTCLIFFE, of Castle Mills, Idle, near Leeds, in the County of York,
Cotton Doubler, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifth day of March, in the year of
our Lord One thousand eight hundred and seventy-two, in the thirty-
fifth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Robert Sutcliffe, Her special licence that I,
the said Robert Sutcliffe, my executors, administrators, and assigns, or
such others as I, the said Robert Sutcliffe, 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 make, use, exercise, and vend, within the
United Kingdom of Great Britain and Ireland, the Channel Islands,
and Isle of Man, an Invention for "AN IMPROVEMENT IN STEAM ENGINE
LUBRICATORS," upon the condition (amongst others) that I, the said
Robert Sutcliffe, 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.

page_text: NOW KNOW YE, that I, the said Robert Sutcliffe, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement and accompanying Sheet of Drawings (that is to
say
This Invention relates to the apparatus employed for the admission or
the passing of tallow into the cylinder or cylinders of steam engines for
lubricating the piston or pistons thereof, and my improvement consists
in the application to the ordinary apparatus of an additional chamber
O and tap. The apparatus as heretofore constructed consists of a chamber
with a tap on each side, one as inlet from the tallow cup and the other
as inlet to the cylinder. In practice it is found that where high pressure
steam is used the taps are soon rendered leaky and deficient, however
well fitted, and so the apparatus becomes inoperative. Now I find that
by the addition of another chamber or chambers, and a tap or taps
betwixt the cup and the cylinder, the evil is remedied, because the action
or pressure of the steam is distributed; that is to say, one tap serves to
protect the other, and so by distribution of wear and tear lubricators so
constructed are rendered effective and serviceable.
In order that this Invention may be clearly understood I refer to the
annexed Sheet of Drawings of a lubricator constructed in accordance
therewith.
A is the ordinary tallow cup for the introduction or reception of
tallow (or other lubricant); B is the inlet tap to admit of the passage of
the said tallow into the chamber or cistern C, and to retain it therein;
D is another tap to allow the passage of the tallow out of the chamber C
(ordinarily into the steam cylinder), but in this case into another or
additional chamber E, to the bottom part of which is an additional tap F
to be fixed in the cylinder cover for the admission of the tallow or
lubricant into the steam cylinder.
The method of using this lubricator or apparatus is as follows:-The
tallow or lubricant is first placed in the cup A, and the taps D and F
being closed the tap B must be opened, when by the heat of the said
cup or apparatus the tallow will be dissolved and pass into the chamber
or cistern C; then the tap A may be closed and the tap D opened, when
the tallow will pass into the chamber E; the tap B being then closed
and the tap opened, the tallow will flow into the steam cylinder G.

page_text: It will thus be seen that there are always two of the taps closed, so that
steam will be prevented escaping from the cylinder, the one tap being a
protection to the other, so that by effectually trapping any escape of
steam its cutting action is counteracted, the efficiency of the lubricator
is maintained, and its wear and tear is reduced to a minimum.
-
Having thus described the nature of the said Invention, and shewn by
Drawings in what manner the same is to be performed or carried into
practice, I would have it understood that I do not claim as my Invention
the cup and cistern with an upper and a lower tap, such having been
used heretofore, nor do I confine myself to two cups and three taps; but
what I do claim is, the construction and use of steam engine lubricators
having two or more cisterns or chambers in combination with three or
more taps, in manner and for purposes substantially as shewn and
described.
In witness whereof, I, the said Robert Sutcliffe, have hereunto set
hand and seal, this Eighteenth day of July, in the year of our
Lord One thousand eight hundred and seventy-two.
