PROVISIONAL SPECIFICATION.
An Improved Combination Fitting for Preventing Water Service
Pipes from Bursting through Frost, applicable as a Stop Cock
and Two Draw off Taps.
HENRY JAMES MINSHAW of 1 Miles Cottages Spicer Street Bridge Road
Battersea in the County of Surrey Plumber and Sanitary Engineer do hereby
declare the nature of this invention to be as follows:-
The object of my invention is to provide a simple combination fitting which can
be used in frosty weather so as to prevent the bursting of water supply or service
pipes.
The said combination fitting is constructed with a stop cock in the centre and
two outlet sockets near to each end. Into these sockets either draw off taps or
plugs are inserted.
My combination stop cock with draw off taps or plugs is fixed to the service pipe
near to the main.
In the event of frosty weather the water supply to cisterns can be cut off and
the water drawn out by the draw off tap or movable plug on that side of the stop
cock.
At the other side of stop cock (nearest to the main) a constant supply of water
can be obtained from the draw off tap or movable plug.
The body of the combination fitting is made in one brass casting. I prefer to fix
it near to the water main there being no risk of breakage or bursting from frost in
that part of service pipes.

COMPLETE SPECIFICATION.
An Improved Combination Fitting for Preventing Water Service
Pipes from Bursting through Frost, applicable as a Stop Cook
and Two Draw off Taps.
I HENRY JAMES MINSHAW of 1 Miles Cottages, Spicer Street Bridge Road
Battersea in the County of Surrey Plumber and Sanitary Engineer, 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, reference being had to the accompanying drawings and to the letters
and figures marked thereon:-
The object of my invention is to provide a simple combination fitting which when
fixed can be used in frosty weather so as to prevent the bursting of water supply or
service pipes.
The said combination fitting is constructed with a stop cock in the centre and
two receiving or outlet sockets near each end. Into these sockets either draw off
taps or plugs are inserted.
°
My combination stop cock with draw off taps or plugs is fixed in the service or
supply pipe near to the water main in any house or building.
In the event of frosty weather the water supply can be cut off and the dead water
be drained out of the pipes by unscrewing and taking out the plug at that side
of the stop cock; or a draw off tap may be inserted into the receiving or
outlet socket in place of the said plug thereby preventing the said pipes from
freezing

page_text: At the other side of stop cock (nearest to the main) a supply of water can be
obtained by removing the plug and inserting a draw off tap into the receiving or
outlet socket at that side.
The body of my combination fitting is made in one brass casting or other
suitable metal. I prefer to fix it near to the water main there being less risk of
breakage or bursting from frost in that part of service pipes owing to the circulation
of water in main.
Referring to the drawings
Fig. 1 shows a section of the body of my combination fitting in one casting of
brass or other suitable metal.
A the receiving or outlet socket for a draw off tap or plug nearest to the
main.
B the water ways constructed similar to an ordinary stop cock.
C the receiving or outlet socket for a draw off tap or plug nearest house or
building.
Fig. 2. shows an outside view with plugs.
To carry out my invention I fix the said combination fitting in the service pipe
near to the water main. I insert a moveable plug or draw off tap into each of the
outlet or receiving sockets A, and C; also the ordinary fittings to form the stop
cock in that part of my fitting marked B in the drawing referred to.
It can then be brought into use by shutting off the supply to the house or
building and drawing off the dead water from the pipes by means of a draw off tap
or by removing the plug from the receiving or outlet socket nearest to the house or
building. At the other side of the stop cock nearest to the main I remove the plug
from the other receiving or outlet socket and insert a draw off tap so as to get a
supply of water direct from the water main.
I do not confine myself to the precise form of the fitting illustrated, as it
may be varied to suit the requirements without affecting the principle of the
invention.
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 :-
1. Constructing a fitting in one casting of brass or other suitable metal
substantially in the manner and for the purposes hereinbefore described.
