Year: 1868

page_text: LETTERS PATENT to Henry Bailey and Frederick Bailey, of East
Retford, in the County of Nottingham, Gas Engineers, for the
Invention of "AN IMPROVEMENT IN THE MANUFACTURE OF VALVES FOR
MIT PAGGAGE OF AID WAMED OR ANY OTHER LOH OR FLUID
"
Sealed the 24th November 1868, and dated the 28th May 1868.
PROVISIONAL SPECIFICATION left by the said Henry Bailey and
Frederick Bailey at the Office of the Commissioners of Patents,
with their Petition, on the 28th May 1868.
We, HENRY BAILEY and FREDERICK BAILEY, of East Retford, in
the County of Nottingham, Gas Engineers, do, hereby declare the
nature of the said Invention for "AN IMPROVEMENT IN THE MANUFACTURE
OF VALVES FOR THE PASSAGE OF AIR, WATER, OR ANY OTHER LIQUID OR FLUID,"
to be as follows:-
The body of the valve may be made of any of the usual forms and
with any suitable number of connections. In one side thereof (by
preference the upper side or top) immediately opposite to the valve
seat is formed an opening of rather larger diameter than the valve

page_text: itself and having a screw thread on its interior circumference; into
this opening is screwed a cover having an octagonal or other suitably
formed collar so that it may be readily screwed in or removed by means
of a spanner or key; through the centre of this cover passes the valve
spindle, the upper part thereof working through a stuffing box attached
or formed in the upper side of the cover and its lower part being
screwed with a square thread and working through a screwed nut
formed on the lower side of the cover. The upper end of the spindle
is provided with a wheel or handle for turning the same so as to open
or close the valve, which latter is attached to the lower extremity of
the spindle. The valve is provided with three or more straight guides
working inside the seat to keep the former in its proper position.
These valves are adapted for all hot or cold liquids and for air or gas;
from their great simplicity they are not liable to get out of order, and
by simply unscrewing the metal cover with a key or spanner the
working parts may be got at and repaired or renewed without breaking
or interfering with any joints in the piping.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry Bailey and Frederick Bailey in the Great
Seal Patent Office on the 27th November 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, HENRY
BAILEY and FREDERICK BAILEY, of East Retford, in the County of
Nottingham, Gas Engineers, send greeting..
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-eighth day of May, in the year
of our Lord One thousand eight hundred and sixty-eight, in the thirty-
first year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said Henry Bailey and Frederick Bailey, Her
special licence that we, the said Henry Bailey and Frederick Bailey,
our executors, administrators, and assigns, or such others as we, the
said Henry Bailey and Frederick Bailey, 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
-

page_text: United Kingdom of Great Britain and Ireland, the Channel Islands,
and Isle of Man, an Invention for "AN IMPROVEMENT IN THE MANUFAC-
TURE OF VALVES FOR THE PASSAGE OF AIR, WATER, OR ANY OTHER LIQUID OR
FLUID," upon the condition (amongst others) that we, the said Henry
Bailey and Frederick Bailey, our executors or administrators, by an
instrument in writing under our, or one of 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 Bailey and Frederick
Bailey, 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 following statement in writing, reference
being had to the accompanying Sheet of Drawings, that is to say :-
The body of the valve may be made of any of the usual forms and
with any suitable number of connections. In one side thereof (by
preference the upper side or top) immediately opposite to the valve
seat is formed an opening of rather larger diameter than the valve
itself and having a screw thread on its interior circumference; into
this opening is screwed a cover having an octagonal or other suitably
formed collar so that it may be readily screwed in or removed by
means of a spanner or key; through the centre of this cover passes
the valve spindle, the upper part thereof working through a stuffing box
attached to or formed in the upper side of the cover, and its lower part
being screwed with a square thread and working through a screwed nut
formed on the lower side of the cover. The upper end of the spindle
is provided with a wheel or handle for turning the same so as to open
or close the valve, which latter is attached to the lower extremity of
the spindle. The valve is provided with three or more straight guides
working inside the seat to keep the former in its proper position.
These valves are adapted for all hot or cold liquids and for air or gas, and
from their great simplicity they are not liable to get out of order, and
by simply unscrewing the metal cover with a key or spanner the
working parts may be got at and repaired or renewed without breaking
or interfering with any joints in the piping.

page_text: Such being the nature and object of our said Invention for "An
Improvement in the Manufacture of Valves for the Passage of Air,
Water, or any other Liquid or Fluid," we will now proceed to describe
more in detail the manner in which the same is to be or may be
performed or carried into practical effect; and in order that the same
may be distinctly understood we have annexed hereunto a Sheet of
Drawings illustrative thereof, and have marked the same with figures
and letters of reference corresponding with those in the following
explanation thereof, that is to say:-
Figure 1 is a front elevation of our improved valve; Figure 2, a front
elevation with part of the body removed shewing the internal arrange-
ment; Figure 3, a side elevation with another shape of valve case and
having more connections; Figure 4 shews the valve seat connected
and the addition of an india-rubber washer, and Figures 5 show the same
detached.
It will be seen on reference to Figure 2 of the Drawings hereunto
annexed that the valve case has (by preference at the top) an opening a
(of rather larger diameter than the valve itself) having a screw thread b
cut on its interior circumference; into this opening is screwed the
cover c, through the centre of which passes the valve spindle d, the
upper part of which works through a stuffing box e, and the lower part
having a square thread f working through a screwed nut 9 formed on
the lower part of the cover c. The cover c has an octagonal or other
suitably formed collor, so that it may be readily screwed in or removed
by means of a spanner or key. The upper end of the spindle d is
provided with a wheel or handle h for turning the same so as to open
or close the valve i (Figures 2 and 4) which is attached to the lower
extremity of the spindle. The valve i is provided with three or more
straight guides (Figures 2, 4, and 5) working inside the seat to keep
the former in its proper position; it may also be provided with an
india-rubber washer (Figures 4 and 5) to keep the same perfectly
tight.
Having now described the nature and object of our said Invention
for "An Improvement in the Manufacture of Valves for the Passage
of Air, Water, or any other Liquid or Fluid," together with the manner
in which the same is to be or may be performed or carried into practical
effect, we would remark in conclusion that we claim as our Invention,

page_text: the improvement in the manufacture of valves, substantially as
herein-before described and shewn on the accompanying Sheet of
Drawings, or any modification thereof, constructed and operating in a
similar manner.
In witness whereof, we, the said Henry Bailey and Frederick Bailey,
have hereunto set our hands and seals, this Twenty-fifth day of
November, in the year of our Lord One thousand eight hundred
and sixty-eight.
