PROVISIONAL SPECIFICATION.
Improvements in Stop Valves applicable for Hot Water Circulating
Apparatus and other purposes.
1, ROBERT RENTON GIBBS, of Mill Street, Liverpool, in the County of
Lancaster, do hereby declare the nature of this invention to be as follows:-
This invention relates to an improved three and four way valve adapted to be
employed more especially in connection with hot water circulating apparatus but it
may also be used for steam and other purposes.
It is constructed somewhat similar to an ordinary screw down valve but having a
branch at right angles to the ordinary entrance and exit pipes.
The branch aforesaid has a passage (preferably rectangular) through it, and
opening into the valve casing a little above and at right angles to the ordinary
passage so that when the valve is down on its seat, the passage in the branch is in
communication with the water or steam entering, or, when the valve is raised the
passage to the branch is closed and the ordinary passage opened.
If used as a three way valve, the branch is simply a straight pipe, but, if used as
a four way valve it will have to take the form of a tee piece..
By means of this improved valve, the circuit can be shortened or lengthened at
will by simply turning the hand wheel attached to the valve.

COMPLETE SPECIFICATION.
Improvements in Stop Valves applicable for Hot Water Circulating
Apparatus and other purposes.
I, ROBERT RENTON GIBBS of Mill Street, Liverpool, in the County of
Lancaster, Hot Water 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 :-
This invention relates to an improved three and four way valve adapted to be
employed more especially in connection with hot water circulating apparatus but it
may also be used for steam and other purposes.
The manner in which I prefer to carry out my invention will be best understood
by reference to the accompanying drawings, in which-
Figures 1, 2 and 3 are a longitudinal section, a transverse section, and a sectional
plan respectively of my improved four way valve;
Figure 4 is a sectional plan of my three way valve, and Figure 5 a cross section
through the branch.
In these figures, the valve is constructed somewhat similar to an ordinary
screw down valve but having a branch at right angles to the ordinary entrance and
exit pipes A and B.
The branch aforesaid has a passage C (preferably rectangular) through it. This
passage is located at right angles to the pipes A and B, and it opens into pipe A. a
little above the valve seating D, so that when the valve E is down on its seat, the
passage C is in communication with the water or steam entering, or when the valve
is raised, the passage C of the branch is closed and the passages A and B opened.
If used as a three-way valve, the branch is simply a straight pipe (Figure 4) but
if used as a four-way valve, it will have to take the form of a tee-piece (Figure 3).

page_text: By means of this improved valve, the circuit can be shortened or lengthened at
will by simply turning the hand wheel F attached to the valve. It will be seen
therefore that by raising the valve the entrance to the branch will be closed, and
steam or water will flow through the pipes A and B in the direction of the dotted
arrows, but by lowering the valve on its seat, the entrance to the branch will be
opened, the pipe B closed and the circuit will be shortened, the current flowing as
depicted by the arrows with full lines.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I déclare that what I
claim is―
The improved construction or arrangement of three or four way valves
substantially as and for the purposes described, whereby, when the valve is down on
its seat, the passage in the branch is in communication with the water or steam
entering, or when the valve is raised the passage to the branch is closed and the
ordinary passage opened.
