AN AUTOMATIC WATER OR OTHER FLUID REGULATOR
Year: 1872

page_text: LETTERS PATENT to William Frederick Heshuysen, of Amsterdam,
Holland, at present of 123, Chancery Lane, in the County of
Middlesex, for the Invention of "AN AUTOMATIC WATER OR OTHER
FLUID REGULATOR."
Sealed the 2nd August 1872, and dated the 17th February 1872.
PROVISIONAL SPECIFICATION left by the said William Frederick
Heshuysen at the Office of the Commissioners of Patents, with his
Petition, on the 17th February 1872.
I, WILLIAM FREDERICK HESHUYSEN, of Amsterdam, Holland, at
present of 123, Chancery Lane, in the County of Middlesex, do hereby
declare the nature of the said Invention for "AN AUTOMATIC WATER OR
OTHER FLUID REGULATOR," to be as follows:-
My Invention relates to improvements on an Invention for which
Letters Patent were granted to Jan Anthony Muller, dated 8th Sep-
tember 1869, No. 2648, for "Measuring and Registering the Flow of

page_text: Water and other Liquids," and is intended to regulate the quantity of
water or other fluid at certain points in the pipes, according to the
quantity taken in at the outer ends.
The improvements consist in lining that part where the "automatic
water regulator" is joined with an india-rubber tube inside, which is 5
compressed by a plunger passing through a hole in the pipe in a cylinder
with a disc, and covered with an elastic face.
The movable part, viz., the elastic face, disc, and plunger, is contained
in a cylinder and made air-tight by a metal cover; the air in this cover
is compressed by the water or other fluid out of the pipes through 1
another pipe, and so the motion of shutting or opening the india-rubber
lined pipe takes place according to the difference in pressure in the main
service pipes.
SPECIFICATION in pursuance of the conditions of the Letters Patent, 1
filed by the said William Frederick Heshuysen in the Great Seal
Patent Office on the 17th August 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
FREDERICK HESHUYSEN, of Amsterdam, Holland, at present of 123,
Chancery Lane, in the County of Middlesex, send greeting.

WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventeenth day of February, in the year
of our Lord One thousand eight hundred and seventy-two, in the
thirty-fifth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said William Frederick Heshuysen, Her
special licence that I, the said William Frederick Heshuysen, my execu-
tors, administrators, and assigns, or such others as I, the said William
Frederick Heshuysen, my executors, administrators, and assigns, should
at any time agree with, and no others, from time to time and at all

page_text: The india-rubber lining of the supply pipe is represented by the
broad line A (see Figs. 1 and 2), and at B is the air passage communi-
cating with "Muller's water meter" when said meter is used.
At a

page_text: the supply pipe is perforated to admit the plunger C. This plunger C
is armed with a disc b consisting of two plates of required dimensions.
Between these two plates I fasten an india-rubber face A³, which covers
a cylinder D and keeps the plunger in position. The cylinder D is
covered at the top with a metallic face E provided with holes c to give
free access to the air. This working part of the regulator is enclosed in
a metallic air-tight cover F. The liquid after passing the contracted
part of the supply pipe has free access to the air-tight chamber formed
by the cover F through the pipe G.
In the direction of the arrow H is or are the cock or cocks for
drawing off the, liquid, and when the said cock or cocks is or are
shut a back pressure is caused, the liquid acts through the pipe G, and
filling the air-tight chamber formed by the cover F presses upon the
disc and india-rubber face A¹, forcing the plunger C up through the
hole at a in the supply pipe, thus compressing the india-rubber lining A,
and shutting the contracted part of the pipe, as shown in broken lines,
Fig. 1.
As the liquid is drawn off by the cock or cocks in the direction
of the arrow H the pressure is diminished and the moveable part of the
regulator, consisting of the india-rubber face A¹, the disc b, and the
plunger C, is lowered, the passage through the contracted part of the
supply pipe being opened to its full extent when the said outlet cock or
cocks is or are turned on to admit of the full flow of the liquid.
When regulators are required to be very sensitive I arrange across the
supply pipe a similar regulator to that just described, enlarging the supply
pipe and inserting therein above the regulator a cone marked I (see
Fig. 2), or a valve may be used instead of the cone.
Instead of lining the supply pipe I shut the water off by an india-
rubber face K, and let the fluid run through one or two or more siding
pipes L, L', of suitable size, and a back pressure is caused by turning
or closing the cock or cocks in the direction of the arrow H, which back
pressure actuates the plunger C in the same manner as before described,
opening and closing the supply pipe by lowering or elevating the cone I
(or valve, as the case may be,) when the outlet cock or cocks are turned
on or off.
Having now deseribed me said Invention I claim the use of the hook

page_text: arrow H, in connection with the herein-before described mechanism for
automatically regulating the flow of water or other fluids, substantially
as herein set forth.
In witness whereof, I, the said William Frederick Heshuysen, have
hereunto set my hand and seal, this Thirteenth day of August,
in the year of our Lord One thousand eight hundred and seventy-
two.
