Year: 1877

page_text: LETTERS PATENT to John Howard, of 1, West Street, Erith, in the County of
Kent, Engineer, and Alexander Fairlie Wilson, and Henry William Alfred
Kingdom, both of 34, St. George's Road, Southwark, County of Surrey,
Engineers, for the Invention of "IMPROVEMENTS IN AUTOMATIC APPARATUS
FOR REGULATING THE FLOW OF LIQUIDS UNDER PRESSURE AND PREVENTION OF
WASTE OF WATER."
Sealed the 7th May 1878, and dated the 7th November 1877.
PROVISIONAL SPECIFICATION left by the said John Howard, Alexander
Fairlie Wilson, and Henry William Alfred Kingdom at the Office of the
Commissioners of Patents on the 7th November 1877.
JOHN HOWARD, of 1, West Street, Erith, in the County of Kent, Engineer, and
ALEXANDER FAIRLIE WILSON, and HENRY WILLIAM ALFRED KINGDOM, both of
"IMPROVEMENTS
34, St. George's Road, Southwark, County of Surrey, Engineers.
IN AUTOMATIC APPARATUS FOR REGULATING THE FLOW OF LIQUIDS UNDER PRES-
SURE AND PREVENTION OF WASTE OF WATER."
A water waste preventer valve of similar construction to that shewn in Figure 11,
Howard's Specification, of February 26th, 1876, No. 799, has attached to it the
conduit E and cone equilibrium regulator F, shewn in Figures 2, 3, and 4 of
Drawing, the action of which is that by raising the said cone equilibrium regu-
lator F by a screw turned by an ordinary box or other key or in any other
convenient manner; then an increased quantity of water passes by the aperture G
to the interior of the cylinder, the weight A falls more quickly upon its seating
and the flush of water is consequently reduced. On the contrary, by depressing or
screwing home said cone equilibrium regulator F the aperture G is diminished, the
weight A remains longer suspended and the flow of water becomes increased; this
conduit takes the place of the aperture in Figure 11, Howard's Specification,

page_text: No. 799, before mentioned, the improvements consisting in the facility of adjusting
and regulating the flush of water required from the outside after the valve has been
fixed, and independently of the head or pressure of water to which it is subject.
The conduit D in the Drawing corresponds to the outlet K in Howard's Specifi-
cation, No. 799, Figure 11, before mentioned, but instead of being left in the
manner therein shewn it is carried down the outside of the cylinder, forming part
of the same casting and enters the outlet O, as shewn; the improvement consists
in additional compactness and in the saving of a coupling and solder joint, in
attaching a pipe to the flush entry pipe of the closet pan.
The weight A is made to close upon the outlet and requires no cup leather.
The cushion is formed by an india-rubber disc secured in the manner shewn, resting
when shut upon a raised brass seating, and having a small hole in the centre to
allow the escape of water which may find its way underneath, and thus interfere
with the elasticity or form of the cushion. This weight is by preference made of
pure tin or of a composition of lead and tin, zinc, or other amalgam, electro-plated
with nickel, or of a brass shell filled with lead and tinned on the outside, the object
being to obtain a substance not easily corrodable by the action of water; but any
other substance may be used which may be found equally suitable. For the same
reason it is advisable to tin the inside of the brass cylinder, or otherwise cover it
with a non-corrodable substance.
The weight B in the Drawing corresponds to e in Howard's Specification, No. 799,
before mentioned, but carries an india-rubber cushion on its upper side, which
closes against an inverted brass seating in the cover instead of the brass seating
being upon the weight and the india-rubber cushion being upon the cover, as shewn
in Drawing of Specification No. 799, Figure 11, before mentioned; the improve-
ment consisting in a lesser liability to warp in the india-rubber when fixed, as now
shewn, and consequently greater efficiency in action.
Upon withdrawal from the cylinder of the weight B, or upon manufacture
without this weight the action is that of a flush regulator only, corresponding to
Figure 111, Howard's Specification, No. 799, before mentioned, with the difference
that the weight A shuts upon the outlet and no cup leather in necessary, that a
cone equilibrium regulator F is carried outside, and that the relief outlet is carried
at once and in the same casting to the outlet O.
Protection is solely claimed for improvements as specified applicable to the
water waste preventer valve and flush regulator, shewn in Drawing, Figures 11
and 111, Howard's Specification, No 799, already mentioned. For the special form
and arrangements of the valve and regulator, as now shewn in the accompanying
Drawing, Figures 1, 2, 3, and 4, and the design as a whole in so far as said
improvement, special form, and arrangements and design are not already protected.
Figure 1 represents an outside elevation of the valve or regulator.
Figure 2 represents in section the valve open, but acting as a water waste
preventer, self-closing, although the spindle is held up; the weight B being hard
against its seating and water entering by the aperture G, so as gradually to
restore the equilibrium of pressure inside the cylinder and allow the suspended
weight A to fall upon its seating.
Figure 3 represents a further stage; the spindle is still held up, but the weights
A and B are upon their respective seatings, and the flow of water is stopped.
Figure 4 represents the valve, with the spindle or handle dropped, and weights A
and B in the positions they occupy when the valve is fully shut.

34, St. George's Road, Southwark, County of Surrey, Engineers. " IMPROVE-
MENTS IN AUTOMATIC APPARATUS FOR REGULATING THE FLOW OF LIQUIDS UNDER
PRESSURE AND PREVENTION OF WASTE OF WATER."
A water waste preventer valve, of similar construction to that shewn in Fig. 11,
Howard's Specification of February 26, 1876, No. 799, has attached to it the
conduit E and cone equilibrium regulator F, shewn in Figs. 2, 3, and 4 of Drawing,
the action of which is that by raising the said cone equilibrium regulator F by a
screw turned by an ordinary box or other key or in any other convenient manner;
then an increased quantity of water passes by the aperture G to the interior of the
cylinder, the weight A falls more quickly upon its seating and the flush of water is
consequently reduced. On the contrary, by depressing or screwing home said cone
equilibrium regulator F the aperture G is diminished, the weight A remains longer
suspended, and the flow of water becomes increased; this conduit takes the place of
the aperture h in Fig. 11, Howard's Specification, No. 799, before mentioned, the
improvements consisting in. the facility of adjusting and regulating the flush of
water required from the outside after the valve has been fixed, and independently
of the head or pressure of water to which it is subject.
The conduit D in the Drawing corresponds to the outlet K in Howard's Specifi-
cation, No. 799, Figure 11, before mentioned, but instead of being left in the
manner therein shewn it is carried down the inside of the cylinder, forming part of
the same casting, and enters the outlet O, as shewn; the improvement consists in
additional compactness and in the saving of a coupling and solder joint in attaching
a pipe to the flush entry pipe of the closet pan.
The weight A is made to close upon the outlet and requires no cup leather.
The cushion is formed by an india-rubber disc secured in the manner shewn, resting
when shut upon a raised brass seating, and having a small hole in the centre to
allow of the escape of water which may find its way underneath, and thus interfere
with the elasticity or form of the cushion. This weight is by preference made of
pure tin or of a composition of lead and tin, zinc, or other amalgam, electro-plated
with nickel, or of a brass shelled filled with lead and tinned on the outside, the object
being to obtain a substance not easily corrodable by the action of water; but any
other substance may be used which may be found equally suitable. For the same
reason it is advisable to tin the inside of the brass cylinder, or otherwise cover it
with a non-corrodable substance.
The weight B in the Drawing corresponds to e in Howard's Specification, No. 799,
before mentioned, but carries an india-rubber cushion on its upper side, which closes
against an inverted brass seating in the cover instead of the brass seating being
upon the weight and the india-rubber cushion being upon the cover, as shewn in
Drawing of Specification No. 799, Fig. 11, before mentioned; the improvement
consisting in a lesser liability to warp in the india-rubber when fixed, as now
shewn, and consequently greater efficiency in action.
Upon withdrawal from the cylinder of the weight B, or upon manufacture
without the weight the action is that of a flush regulator, only corresponding to
Figure 111, Howard's Specification, No. 799, before mentioned, with the difference
that the weight A shuts upon the outlet and no cup leather is necessary, that a
cone equilibrium regulator F is carried outside, and that the relief outlet is carried
at once and in the same casting to the outlet O.
Figure 1 represents an outside elevation of the valve or regulator.
Figure 2 represents in section the valve open, but acting as a water waste pre-

page_text: venter, self-closing, although the spindle is held up, the weight B being hard against
its seating, and water entering by the aperture G, so as gradually to restore the
equilibrium of pressure inside the cylinder and allow the suspended weight A to fall
upon its seating.
Figure 3 represents a further stage; the spindle is still held up, but the weights
A and B are upon their respective seatings and the flow of water is stopped.
Figure 4 represents the valve, with the spindle or handle dropped, and weights A
and B in the positions they occupy when the valve is fully shut.
Having thus described the nature of our said Invention, we declare that what we
élaim and desire to be secured to us by the herein-before recited Letters Patent is,
the improvements, as specified, applicable to the water waste preventer valve and
flush regulator, shewn in Drawing, Figs. II, and III., Howard's Specification,
No. 799, already mentioned, for the special form and arrangement of the valve and
regulator, as now shewn in the accompanying Drawings, Figs. 1, 2, 3, and 4, and the
design as a whole; in so far as said improvements, special form, and arrangements,
and design are not already protected.
.
In witness whereof; I, the said Alexander Fairlie Wilson, on behalf of myself
and the said John Howard and Henry William Alfred Kingdom, have here-
unto set my hand and seal; this Sixth day of May, in the year of our Lord
One thousand eight hundred and seventy-eight.
