IMPROVED APPARATUS FOR LUBRI- CATING PISTONS
Year: 1858

page_text: LETTERS PATENT to Joseph Westerby, of Huddersfield, in the County of
York, Engineer, for the Invention of "IMPROVED APPARATUS FOR LUBRI-
CATING PISTONS."
Sealed the 19th October 1858, and dated the 26th April 1858.
PROVISIONAL SPECIFICATION left by the said Joseph Westerby at the
Office of the Commissioners of Patents, with his Petition, on the
26th April 1858.
I, JOSEPH WESTERBY, of Huddersfield, in the County of York, Engineer,
do hereby declare the nature of the said Invention for "IMPROVED APPARATUS
FOR LUBRICATING PISTONS," to be as follows:-
This Invention is applicable to the lubricating of pistons of steam or other
engines or machines, and consists of a simple and effective self-acting
apparatus for supplying oil or tallow to such pistons without the use of any
revolving or moving mechanism.
On each side of the cylinder is an air-tight glass vessel to contain the oil or
lubricating material, in the interior of which is a syphon pipe connected by
means of a tap to a bent pipe communicating with the cylinder about midway
of the stroke of the piston. The oil or other lubricating fluid is placed in
the vessels, and passes through the syphons and down the pipes into the
cylinder, the quantity being regulated by the taps. When the pressure of the

page_text: steam or other fluid is full on, the syphons and pipes present a column of
resistance fully equal to the force. When the steam is off and the piston
down, or when the piston is above the entrance of the oil or grease into the
cylinder, the supply is self-acting, and amply meets all demands.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Joseph Westerby in the Great Seal Patent Office on the
26th October 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPII
WESTERBY, of Huddersfield, in the County of York, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-sixth day of April, in the year of our Lord
One thousand eight hundred and fifty-eight, in the twenty-first year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Joseph Westerby, Her special licence that I, the said Joseph
Westerby, my executors, administrators, and assigns, or such others as I, the
said Joseph Westerby, 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 "IMPROVED APPARATUS
FOR LUBRICATING PISTONS," upon the condition (amongst others) that I, the
said Joseph Westerby, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should parti-
cularly 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 Joseph Westerby, 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 fol-
lowing statement in writing, and on reference to the accompanying Drawings,
that is to say:-
My Invention is applicable to the lubricating of the pistons of steam or
other engines or machines, and consists of a simple and effective self-acting
apparatus for supplying oil or tallow to such pistons without the use of any
revolving or moving mechanism whatever.

page_text: On each side of the cylinder is an air-tight vessel of glass, or other suitable
material to contain the oil or lubricating matter, in the interior of which is a
syphon pipe connected by means of a bent pipe, furnished with a tap, and
communicating with the cylinder about midway of the stroke of the piston,
which pipe is furnished with a check valve opening only towards the cylinder.
The oil or other lubricating fluid is placed in the vessels, and passes through
the syphons, and down the bent pipe into the cylinder, the quantity being
regulated by means of the taps. When the pressure of the steam or other
fluid is full on, the syphons and pipes present a column of resistance fully
equal to the force. When the steam is off and the piston down, or when the
piston is above the entrance of the oil or grease into the cylinder, the supply
is self-acting, and amply meets all demands.
In the Drawing annexed to these Presents I have represented various
modifications or adaptations of my Invention, showing its application to both
high and low-pressure engine cylinders, and have marked the same. with
figures and letters of reference corresponding with those in the following
explanation thereof :-
b
Figure 1 shows three forms of the apparatus for conveying the lubricating
matter to the interior of the cylinder under various circumstances. A repre-
sents the apparatus so arranged that steam can be introduced above the lubri-
cating material. a, a, is the glass or other vessel containing the lubricating
matter which is introduced at the top, and the opening closed by an air-tight
stopper 6 (such stopper being in all cases screwed or otherwise fastened so as
to resist the pressure from within); c, c, is the bent pipe communicating with
the cylinder and furnished with a tap at d; e, e, is a pipe also furnished with
a tap, and conveying steam from the steam pipe to the vessel above the oil or
lubricating matter; f is the syphon pipe. B shows another arrangement of
the apparatus; a, being the vessel; b, the stopper; c, the bent pipe; d, the
tap; and f, the syphon; and C shows a further modification of the apparatus.
In this arrangement the steam is admitted both above and below the lubri-
cating matter, thus neutralizing or balancing the pressure. In Figure 2, D
and E represent another arrangement of the apparatus, in which the bent
pipe c is made longer, and consequently a longer column of resistance is
obtained, and F represents the apparatus so arranged that the vessel a is
placed below the entrance of the pipe c into the cylinder:
Having now described the nature and object of my said Invention for
"Improved Apparatus for Lubricating Pistons," together with the manner of
carrying the same into practical effect, I would remark in conclusion that my
Invention is obviously capable of great variation, but I wish it to be distinctly

page_text: understood that I claim as my Invention, the application, employment, or use
of self-acting syphons, under any form or variation, for conveying the lubri-
cating matter to the interior of the cylinders of steam or other engines or
machines; and, secondly, the employment of steam to assist the efficient
supply of lubricating material when applied in connection with such syphons,
as represented at A and C, in Figure 1, in the annexed Drawings.
In witness whereof, I, the said Joseph Westerby, have hereunto set my
hand and seal, this Twenty-third day of October, in the year of our
Lord One thousand eight hundred and fifty-eight.
Witness,
WM. BARLOW,
52, New Street,
Huddersfield.
