PROVISIONAL SPECIFICATION.
Apparatus for Regulating the Pressure of Water in Pipes.
I JOHN TWEEDDALE Engineer, 30 Canal Street Paisley in the County of
Renfrew do hereby declare the nature this invention to be as follows:-
This invention has for its object the supplying of houses or any other places.
with water at any suitable pressure sufficient for the purposes required, while the
pressure of water in the main supply pipe, remains either constant or variable.
In carrying my invention into effect, I arrange a cylinder having an inlet.
connected with the main pipe, inside of this cylinder, which has a valve seat at the
one end I fit a piston that has a rod connecting it with the valve. At the valve end
of the cylinder there is a chamber which has an outlet connection to the service
pipe. The piston that is inside of cylinder has a force applied to it by a weight or-
spring and is adjusted to suit the pressure required in the service pipe.

Apparatus for Regulating the Pressure of water in Pipes.
I JOHN TWEEDDALE Engineer 30 Canal Street Paisley in the County of
Renfrew do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement :-
This invention has for its object the supplying of houses or any other places.
with water at any suitable pressure sufficient for the purposes required, while the
pressure of water in the main supply pipe remains either constant or variable.
In carrying my invention into effect, I arrange a cylinder having an inlet.
connected with the main pipe, inside of this cylinder which has a valve seat at the
one end, I fit a piston that has a rod connecting it with the valve. At the valve end
of the cylinder there is a chamber which has an outlet connection to the service
pipe. The piston that is inside of cylinder has a force applied to it by a weight or
spring, and is adjusted to suit the pressure required in the service pipe.
And in order that my said invention may be fully understood, I shall now
proceed more particularly to describe the same, and for that purpose shall refer to
the drawing sent herewith.
The cylinder a has a valve seat at 6 and a chamber at h and is arranged that
water enters from the main pipe at branch c and after passing through the valve f
enters through chamber h into service pipe at branch d. Inside cylinder is fitted
a pistone which moves freely, and is connected to valve f by rod g. Weight k is.
arranged to suit pressure required in the service pipe d.
The manner in which the valve acts is as follows,
When the pressure in service pipe d is reduced by allowing water to flow out,
weight opens the valve f and allows the water from the main to flow through
chamber into service pipe d, and when the water in service pipe d rises to the
pressure required the water from the main pressing on piston e closes valve f.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
An arrangement composed of cylinder, weight, piston and valve so as to give a
different pressure of water in the service pipe from what is in the main pipe.
Dated this 24th day of April 1896.
