Year: 1873

page_text: LETTERS PATENT to Henry Sutcliffe and Wright Sutcliffe, Sanitary
Engineers, of Halifax, in the County of York, for the Invention of
"A NEW AND IMPROVED SAFETY SYPHON VALVE TAP, AND CONNECTIONS FOR
THE SAME, PART OF WHICH IMPROVEMENT IS APPLICABLE TO LUBRICATORS."
PROVISIONAL SPECIFICATION left by the said Henry Sutcliffe and
Wright Sutcliffe at the Office of the Commissioners of Patents,
with their Petition, on the 12th November 1878.
We, HENRY SUTCLIFFE and WRIGHT SUTCLIFFE, Sanitary Engineers,
of Halifax, in the County of York, do hereby declare the nature of the
said Invention for "A NEW AND IMPROVED SAFETY SYPHON VALVE TAP, AND
CONNECTIONS FOR THE SAME, PART OF WHICH IMPROVEMENT IS APPLICABLE TO
LUBRICATORS," to be as follows:-
Our Invention relates to employing a new syphon valve tap or taps,
with improved seating, valve, and packing; such seating, valve, and
packing being applicable to all purposes for regulating tho discharge and
flow of steam, water, or other fluids, also gases.

page_text: For this purpose we employ-
Firstly. Valve taps constructed on the syphon principle, giving a clear,
full, and unobstructive passage equal in area to the pipe to which it
is connected; the syphon valve tap is made circular or of a zig-zag
form.
Secondly. We sink in the seat of the valve tap or lubricator, below the
surface of the seat or valve, a groove, in which is fitted a soft metal
washer made of lead, part lead, or any other suitable material. This
groove retains the metal washer, and prevents the lead or part lead
squeezing out (doing away with the present plan of using a cavity in the
seat or valve), in which is filled lead, thereby preventing leaky and
faulty valves.
Thirdly. The spindle is so constructed that it works the valve in the
cylinder of the valve tap, and adjusts the packing each time the valve
opens; the spindle of the lubricator opens and shuts one or more top and
bottom valves at one operation.
Fourthly. Our stuffing box is constructed with packing composed of
lead, or rings of lead, or of any other suitable material.
Fifthly. We strengthen our syphon valve tap by means of a lock or
web at the bent portions thereof.
Sixthly. We construct the end or ends of the valve tap taper, and
fitted with rings, on which is placed a flexible pipe; the taper end is
made to suit a socket having a thread in its interior to screw on the end
of the valve tap.
SPECIFICATION in pursuance of the conditions of the Letters Patent, 2
filed by the said Henry Sutcliffe and Wright Sutcliffe in the Great
Seal Patent Office on the 12th May 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, HENRY
SUTCLIFFE and WRIGHT SUTCLIFFE, Sanitary Engineers, of Halifax, in
the County of York, send greeting.
:
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twelfth day of November, in the year of
our Lord One thousand eight hundred and seventy-three, in the thirty-

page_text: seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said Henry Sutcliffe and Wright Sutcliffe,
Her special licence, that we, the said Henry Sutcliffe and Wright
Sutcliffe, our executors, administrators, and assigns, or such others as
we, the said Henry Sutcliffe and Wright Sutcliffe, our executors, ad-
ministrators, 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 "A NEW. AND
IMPROVED SAFETY SYPHON VALVE TAP, AND CONNECTIONS FOR THE SAME, PART OF
WHICH IMPROVEMENT IS APPLICABLE TO LUBRICATORS," upon the condition
(amongst others) that we, the said Henry Sutcliffe and Wright Sutcliffe,
our executors or administrators, 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 Henry Sutcliffe and Wright
Sutcliffe, 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 bad
to the Drawing hereto annexed, and to the figures and letters marked
thereon, that is to say :-
The said Invention relates to employing a new syphon valve tap (or
taps), with improved seating, valve, and packing, such seating, valve, and
packing being applicable to all purposes for regulating the discharge and
flow of steam, water, or other fluids, also gases.
For this purpose we employ―
Firstly. Valve taps constructed on the syphon principle, giving a clear,
full, and unobstructive passage equal in area to the pipe to which it
is connected; the syphon valve tap is made circular or of a zig-zag
form.
Secondly. We sink in the seat of the valve tap or lubricator, below the
surface of the seat or valve, a groove in which is fitted a soft metal
washer, made of lead, part lead, or any other suitable material; this

page_text: to the seat E, in which is sunk a groove, and in which is fitted a soft
metal washer H, made of lead, part lead, or other suitable material; the
groove retains the metal washer, and prevents the lead or lead part from
squeezing out, thus doing away with the cavity in the seat or valve here-
tofore employed in which lead is filled; the valve seating is made curved.
or flat. The metal washer fits on the surface of the seat E, allowing the
valve G to slide on the groove F, and in the opening B, when the lead gets
pressed out, and keeping the valve tight on the seat. On the valve G is
formed a spindle R, fitting loosely in the screwed bottom part I of the
spindle J; when the spindle is turned by the hand wheel K, it unscrews the
part I, lifting it up, consequently allowing the valve G to lift. On the
spindle J is formed a collar L, which strikes against the packing M, com-
posed of lead, or rings of lead, or other suitable material, and adjusts the
packing each time the valve opens. The packing M is fitted in a closed
top N of the stuffing box O, formed on the lid or cover P of the valve.
Q, ends of the valve, formed with face projections or hexagonal to screw the
valve to the pipes; or we make the ends or internal tubes taper, and
with corrugated surfaces, for the purpose of fixing flexible pipes thereto
as herein-after described.
Figures 4 and 5 represent a plug tap. A, tap having an inlet
passage B, and an outlet passage C, formed on the syphon principle as
herein-before described. In the tap is fitted a plug D', made hollow. On
the top of this plug D', and screwed on the top part of the tap, is a cap
or cover E for keeping the plug in its place. Between the top part of
the tap and the top of the plug D' is fitted a packing ring F, made of
lead, part lead, or other suitable material. This packing is adjusted by
means of the ring G formed on the cap or cover E; the ring G presses
on the packing ring F, keeping the packing tight and preventing any
leakage. We may construct our taps with hexagonal ends or with taper
ends H, having corrugated surfaces, on which are fitted flexible pipes.
Each pipe is kept firmly fixed by means of a socket I, in which a thread
J is cut, pressing the flexible pipe on the corrugated taper H. On the
socket I is formed a boss K to screw it on to the tap.
Figure 6 represents a condensed water and overflow valve. A, bottom
part of the body of the valve; B, top of the same.
In the bottom part
is formed a valve seat C, in which fits a valve D, with groove containing
lead, or part lead, or other suitable material, as herein-before described.
The valve D works in a guide E, and is attached by means of the spindle

page_text: Fifthly. The construction of lubricators, substantially as described and
represented in the accompanying Drawing.
Sixthly. The corrugated internal tubes or ends of valve or plug taps
in combination with the sockets, having threads cut or cast in their
interior surfaces for connecting flexible tubing, substantially as described
and represented in the accompanying Drawing.
In witness whereof, we, the said Henry Sutcliffe and Wright
Sutcliffe, have hereto set our hands and seals, this Eleventh
day of May, in the year of our Lord One thousand eight
hundred and seventy-four.
