Year: 1852

page_text: LETTERS PATENT to Freeman Roe, of the Strand, in the County of
Middlesex, Hydraulic Engineer, for the Invention of "IMPROVEMENTS
IN VALVES AND COCKS."
Sealed the 19th February 1853, and dated the 1st October 1852.
PROVISIONAL SPECIFICATION left by the said Freeman Roe at
the office of the Commissioners of Patents, with his petition, on
the 1st October 1852.
I, FREEMAN ROE, of the Strand, in the County of Middlesex,
Hydraulic Engineer, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN VALVES AND Cocks," to be as follows:-
This Invention has for its object,-First, Improvements of Cocks where
ball-valves are used; and such improvements consist of combining with
the use of such ball-valves rods sliding freely through stuffing-boxes, so
that the valves may be pushed from their seets by pressure, and when
released the pressure of the fluid on the valves will force them back,

page_text: and also the stems by which they are operated on, in place of using
screws on the stems which act on such valves, as heretofore: Secondly,
it relates to arranging valves or cocks for supplying waterclosets or
other vessels with a measured quantity of water, and consists of arranging
the outlet valve in such manner that it will float and let out the water
from a box or measure, when the pressure of the incoming water is shut
off Thirdly, my Invention relates to sluice-cocks, and consist of
forming dovetail grooves, or grooves, with narrow openings in the
working parts, and--casting therein gutta-percha, so that the. gutta
percha, when cold, will produce a fixed working surface.
SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said Freeman Roe, in the Great Seal Patent Office,
on the 30th March 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FREE-
MAN ROE, of the Strand, in the County of Middlesex, Hydraulic
Engineer, send greeting.

WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the First day of October in the year of our
Lord One thousand eight hundred and fifty-two, in the sixteenth
Her reign, did for Herself, Her heirs and successors, give and grant
unto me, the said Freeman Roe, Her especial licence that I, the said
Freeman Roe, my executors, administrators and assigns, or such others as
I, the said Freeman Roe, 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 Inven-
tion for "IMPROVEMENTS IN VALVES AND COCKS," upon the condition
(amongst others) that I, the said Freeman Roe, by an instrument in
writing under my hand and seal, should particularly describe and ascer-
tain 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

page_text: Patent Office within six calendar months next and immediately after
the date of the said Letters Patent.
NOW KNOW YE, that I, the said Freeman Roe, 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 thereof (that is to say):
This Invention has for its object,-First, Improvements of Cocks where
ball-valves are used; and such improvements consist of combining with
the use of such ball-valves rods sliding freely through stuffing-boxes, so
that the valves may be pushed from their seats by pressure, and when
released the pressure of the fluid on the valves will force them back,
and also the rods by which they are operated upon, in place of using
screws on the stems which act on such valves, as heretofore.
Figure 1, represents an ordinary draw-off or bib-cock; Figure 2,
represents the same arrangements, with a lever and counter balance.
Figure 3, represents a ball-valve for regulating the supply of water to
cisterns, the ball A, pushing down the spindle B, when the cistern is
empty; as the cistern fills the ball floats upwards and liberates the
said spindle B, which allows the valve to rise and close itself; Figure 4,
represents a section of the same cock. A, is the ball-valve; B, the
spindle in the act of pushing down the ball A; C, is a seating of vul-
canized India-rubber, against which the valve seats itself when the
pressure on the spindle is withdrawn.
Secondly, it relates to arranging valves or cocks for supplying waterclosets
or other vessels with a measured quantity of water, and consists of arranging
the outlet valve that it will let out the water from a box when the
pressure from the incoming water is shut off. Figure 5, represents a
watercloset basin E, supplied by a box B, which may be fixed in any
situation; this box is supplied by the cock or valve A, of which the
spindle C, is pressed down by the seat or hand, or any other means; as
soon as the said spindle is released, the valve D, floats (its specific
gravity being lighter than water), allowing the water in the box to
escape into the basin.

page_text: Thirdly, it relates to sluice-cocks or hydrants, and consists of forming
dovetail grooves, grooves, or recesses, or narrow openings in the working
parts of such valves or hydrants, for the fixing of the seats of the valves
and casting or fixing therein gutta percha or metal of a different kind
to the body of the valve when a facing of another kind is required, so
that the gutta percha or metal will produce a fixed working surface. To
carry out my plan and make it effective, the principal feature in the im-
provement consists in being enabled to remove the said valves or seats
to reface them when required; (in the present plan it is often neces-
sary to cut out the old valve and replace it with a new one, so that the
ordinary modes of fixing the seats would be attended with difficulty to
accomplish this purpose.) I propose, as will be seen in the drawing.
Figure 6, represents a sluice-valve complete. Instead of the flanches
which attach the bonnet of the valve being at A, which would render
my Invention valueless, I fix my bonnet with flanges at B, which
comes directly in a line with the main pipe. Figure 7, shows the ground-
plan of the valve with the bonnet taken off, (B, B, is the flanch upon
which the bonnet is fixed,) showing the recesses or grooves A, A, A, A,
into which the scats are slid, consequently they are easily removed for
repairs, &c. Figure 8, shows one of the scats taken out, A, being the
projecting part of gutta percha or metal, X, X, the rabate which slides
into the recesses or grooves A, A, shown in Figure 7. Figure 9, shows
the top edge of the seat Figure 8, X, X, being the parts which slide
into the grooves or recesses A, A, Figure 7. Figure 10, shows the sluice-
valve in section; A, A, are the seats (represented at Figure 8) in their
places; b, b, b, b, show the dovetail grooves into which the gutta percha
or metal is fixed; C, the valve double-faced, through the body of which
the screw passes to enable the valve to be opened or closed at pleasure.
Figure 11, shows a valve in a box, the bottom flanch A, being grooved
or recessed to receive the valve B, which is more fully shown in
Figure 12; Figure 12, is a section of the same. A, A, is the recess or
groove with the valve seating fixed therein; B, is the valve in its
place; C, C, is the dovetail groove to receive the gutta percha or metal.

page_text: It will be seen, therefore, that this valve by being detached from the
flanch of pipe D, that the seating of the valve can be removed at
pleasure.
My claims are, as explained in this specification, Firstly, for a
moveable spindle, as described in connexion with a ball-valve;
Secondly, is the arrangement of the valves to supply waterclosets, &c.;
Thirdly, is the facing, together with the general arrangements and com-
bination of the whole so that the faces can be taken out to repair by
removing the bonnet of valve; and I also claim the mode of arranging
and facing valves and parts as shown in Figures 11, and 12.
In witness whereof, I, the said Freeman Roe, have hereunto set
my hand and seal, this Twenty-ninth day of March in the year
of our Lord One thousand eight hundred and fifty-three.
