Year: 1856

page_text: LETTERS PATENT to Henry Turner Sourbuts, of Hyde, in the County of
Chester, Mechanic, for the Invention of "IMPROVEMENTS IN TAPS OR
VALVES, PART OF WHICH ARE APPLICABLE TO LUBRICATORS FOR STEAM ENGINES
AND OTHER PURPOSES."
Sealed the 22nd May 1857, and dated the 28th November 1856..
PROVISIONAL SPECIFICATION left by the said Henry Turner Sourbuts
at the Office of the Commissioners of Patents, with his Petition, on the
28th November 1856.
I; HENRY TURNER SOURBUTS, of Hyde, in the County of Chester, Mechanic,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
TAPS OR VALVES, PART OF WHICH ARE APPLICABLE TO LUBRICATORS FOR STEAM
ENGINES AND OTHER PURPOSES," to be as follows:-
My Invention consists in making the plug of taps or valves hollow, so that
the passage, instead, of going directly through the plug, as in ordinary taps or
valves, goes into the hollow of the plug at one part of it, and then goes along
the hollow of the plug and comes out at another part of it. By this arrange-
ment the orifices of taps or valves have more covering surface than those of
common construction.
My Invention further consists in applying the above-described improvements
to lubricators. This is accomplished by surrounding the tap or valve, con-
structed as above described, with a closed vessel or receiver for the oil or lubri

page_text: cating matter, and by making an orifice or passage into the end of the plug,
so as to communicate with the steam cylinder or mechanism to be lubricated.
In one position of the plug a communication is opened for the lubricating
matter to pass into the receiver, and in another position of the plug this
passage is shut, and the communication is opened between the steam cylinder
and the receiver for the entrance of the steam and passage out of the lubri-
cating matter.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said, Henry Turner Sourbuts in the Great Seal Patent Office on
the 22nd May 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, J, HENRY
TURNER SOURBUTS, of Hyde, in the County of Chester, Mechanic, send.
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-eighth day of November, in the year of our
Lord One thousand eight hundred and fifty-six, in the twentieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Henry Turner Sourbuts, Her especial license that I, the said Henry
Turner Sourbuts, my executors, administrators, and assigns, or such others as I,
the said Henry Turner Sourbuts, 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 "IM-
PROVEMENTS IN TAPS OR VALVES, PART OF WHICH ARE APPLICABLE TO LUBRICATORS
FOR STEAM ENGINES AND OTHER PURPOSES," upon the condition (amongst others)
that I, the said Henry. Turner Sourbuts, by an instrument in writing under
my hand and seal, 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 Henry Turner Sourbuts, 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 Drawings (that is to say):―
My Invention consists in making the plugs of taps or valves hollow, so that

page_text: the passage,
instead of going directly through the plug, as in ordinary taps or
valves, will enter at one part of the plug, pass along. it, and leave at another
part of it. By this arrangement, the orifices of the passage in the plug, when.
it is turned to interrupt the passage, have more covering surface than when;
the passage goes directly through the plug, as in valves or taps of the common.
construction, which are very liable to leakage, from scanty covering, margin, and,
imperfect fitting, arising from the difficulty of grinding the plug truly, so as to,
fit its limited facing.
This part of my Invention will be readily. understood by reference to the
annexed Sheet of Drawing. Fig. 1 is a longitudinal section, Fig. 2 an outside-
side view, and Fig. 3 an outside top view, of a tap or valve constructed
according to my Invention. The plug in Fig. 1 is supposed to be turned.
so as to leave the passage open. a is the plug; it is kept in its place in
the casing 6 by the gland part c, which is secured by set screws d to the
casing b. Fig. 4 is a section of a tap or valve constructed according to my
Invention, having the common method of securing the plug in its place..
Secondly, my Invention relates to apparatus for lubricating, and consists in
combining arrangements for this purpose with the improvements in taps or
valves described under the first division of my Invention. This is accom-
plished by surrounding a casing having a plug fitted to it, with a closed vessel
or receiver for the oil or lubricating matter, and by making passages in the
plug to allow the lubricating matter to enter the receiver and pass out into
the steam cylinder or to the mechanism to be lubricated. In one position of
the plug the lubricating matter can be poured into the receiver; in other
positions of the plug the passage is closed by which it enters, and other
passages are opened between the receiver and the cylinder to allow the steam
to enter the receiver, and the lubricating matter to pass from it into the steam
cylinder or to mechanism to be lubricated. This part of my Invention is
illustrated by Fig. 5, a section, and Fig. 6, an outside view. b is the casing;
a, the plug, which is kept in position by the gland c and set screws d. The
casing (6) is secured in the globular receiver e, which has provision by which
it can be secured to the part which is to receive the lubricating matter.
handle fis attached to the projecting part of the
g is screwed or otherwise fixed on the end of it.
to the receiver is poured into this funnel, and
formed in the centre of the plug, and then out at the side of it, passing
through an orifice (6¹) in the casing into the receiver (e). The plug (a) is.
shewn in Fig. 5 in that position in which the passage (a) is open for the
entrance of the lubricating matter. There are two more holes in the casing
A
plug (a), and a small funnel
The matter to be supplied
passes down a hollow (a')

page_text: (62 and 63), and corresponding holes (a² and a³), in the plug (a). Only one of
the holes or passages in the plug (a) need be in communication with the
receiver at the same time, and each may be brought in communication by
turning the handle (f) to the required position. In one position, the steam
entering the hollow of the plug will pass through the holes a² and &* into the
upper part of the receiver; in another position the lubricating matter will pass
from the receiver through holes a³ and 6 into the hollow of the plug and
through the passage b*.
I have now particularly described the nature of my Invention, and the
modes of carrying the same into effect; and claim, as my Invention,―
Firstly, taps or valves having their passages arranged substantially in the
manner herein-before described under the first division of my Invention.
Secondly, I claim as my Invention apparatus for lubricating when constructed
substantially in the manner herein-before described under the second division
of my Invention.
In witness whereof, I, the said Henry Turner Sourbuts, have hereunto
set my hand and seal, this Nineteenth day of May, in the year of our
Lord One thousand eight hundred and fifty-seven.
HENRY TURNER SOURBUTS. (L.B.)
