PROVISIONAL SPECIFICATION.
An Apparatus to Stop the Noise of the Inrush of Water to Water
Closet Tanks.
JOHN JAMES SPEAR 70 Crosswell Street Landport Portsmouth Glass
Merchant do hereby declare the nature of this invention to be as follows:-
That the apparatus is a vessel which disconnects the direct water supply, after
which it flows on & serves the tank. The action of which at once diminishes the
hissing noise, and it can be made in either iron or lead. It has three compartments,
the first division is some two inches from the inlet water pipe, & in which division
is an of an inch hole through which the water rushes into the second two inches
chamber when it comes into contact with another division in which are small
perforations, through which the water passes into the largest chamber, to the pipe
which supplies the tank. The perforations will be made to suit the pressure of water
not supplied by water companies such as rain water tanks as the pressure of the
water in that case would not be so great as that supplied by water companies.
The direct action of a half inch water pressure through an half inch pipe
direct upon the ball tap is the cause of the tap making the loud hissing noise.
From this reason, the bore of the ball tap is much less than the bore of the
supply pipe and the pressure of the water so great that the moment the ball of
the tap drops the water gets compressed or in other words cannot get through fast
enough, and between the pressure from behind & the rising of the ball which
closes the valve, that between the two causes all the noise is created.
The thought that occured to my mind was how to counteract that pressure
without interfering with existing tanks, and at the same time supply water
sufficiently quick to the tank for further use.
This has been accomplished by the vessel, the simplicity of which is its beauty,
as there are no valves or intricate works that can get out of order the thing is
complete in itself & has only to be attached to the supply pipe.

Closet Tanks.
JOHN JAMES SPEAR 70 Crosswell Street Landport Glass Merchant do
hereby declare the nature of this invention and in what inanner the same is to
be performed, to be particularly described and ascertained in and by the following
statement :-
That the said apparatus can be made in metals suitable such as lead iron,
copper, brass, and is shapes to suit possition, viz. oblong square, and oblong round.
The size of the square shape at the entrance is 12 long width 6 inches depth
4 inches. The shape tapers to the bottom to make it easy for casting. Running
round the top is an inch lange with a raised rim one inch high from the outside &
CD017

page_text: when the lid with the rubber or leather packing is in possition it would stand about
of an inch higher so as to make a sound joint. The thickness of the metal
would be about of an inch thick that the apparatus would be made of when
⚫casted. The measurements of the inside are 10 loug 4+ at top and 3 at bottom
and the length of bottom 9 inches.
The apparatus is divided into three chambers.and each division has a barrel
in which is an inch hole screwed at the top to receive screwed plugs. The first
chamber A at the inlet has a plumbers union which is tapped to receive a brass
plug G with 5 one sixteenth of an inch holes to stop any plumber's shavings
irom entering the apparatus, the first division of the first chamber A has a
barrel D of an inch below the lid & helow the square of the division to allow
the flow of water to pass through an of an inch hole in the brass screwed plug H
in a downward course to rise again to un hole K immediately under the brass-plug
into the second chamber B here there is another division & barrel E similar but
in this case the brass screwed plug I has three thirty-second parts of an inch
perforations or holes & the water flows in the same manner as in the first
chamber A through an hole L at the top out into the third barrell F in the third
chamber C & through an hole M in this third barrel F at the bottom on to the
tank. The outlet is fitted with a brass union J.
The oblong round shape would be for corners and divided at the centre & the
divisions would be cast in one and fitted in the manner as the oblong square.
The shell would be tapped to receive the division cne inch each side of ceutre
the connections would be by nuts & bolts thick & each brass plug would have a
cut across them so that at any time they could be taken out, should the apparatus
get corroded & the whole apparatus can be taken to pieces & inspected at any
:time.
Having now particularly described and ascertained the nature of my said inven-
tion & in what manner the same is to be performed I declare that what I
claim is
First. Its entire novelty & independent feature as reducing the pressure of the
water on the ball cock by holes & perforations without the use of valves.
Secondly. The action of the chambers as a means of applying the brass plugs
by which the direct force of water is governed or checked before it reaches the
ball cock.
Thirdly. The mode of applying the brass plugs at the inlet as against plumber's
shavings getting into the chamber.
Fourthly. Not only as an independent apparatus, as a water waste preventer &c.
it can be made with any new tanks in the 'future.
Fifthly. By applying the apparatus the presure is saved by at least six to eight
pounds to the square inch that is to say if the presure stands at 25 lbs. to supply a
w.c. tank the moment you serve the tank it will reduce it to 17 pounds untill the
tanks (ordinary) is filled. But in the application of the apparatus if it stands at
25 lbs. it will only reduce the presure by 2 lbs. this 'I have proved by presure guage
glass.
Sixth. The perforations will be made more or less to suite pressure.
