Improvements in Appliances for controlling the Opening and
Closing of Valves.
BENJAMIN RHODES of 240 Bow Road London E. Engineer and Brassfounder do
hereby declare the nature of this invention to be as follows:-
My invention has for its object the better and more certain control of fluids or
liquids of different temperatures when being blended or mixed together so as to
make accidents from scalding impossible.
For this purpose I employ when two or more valves stand side by side at a given
and suitable distance a toothed segment of a wheel working on a centre axle and
geared into a pinion which is fitted upon the spindle of one of the valves say the
valve controlling the colder fluid or liquid. This segment of toothed wheel.'has
attached to it a plate made of metal or other suitable material which forms part of
the wheel segment. When both valve spindles are shut down this plate or shutter
covers the top of the spindle of the valve controlling the hot liquid and will continue
to cover same until the valve controlling the cold. liquid is fully open; the metal.
plate or shutter will then be moved quite clear of the spindle of valve controlling
the hot liquid and this valve can then be opened. When sufficient liquid or fluid
has been drawn off the valve controlling the hot liquid must be shut down before
the valve controlling the colder liquid can be closed.
Attached to the valves are standards to which is fixed a plate made of metal or
other suitable material which covers the valves and plate or shutter and contains
holes made to receive suitable key or keys for opening and closing the valves.

Improvements in Appliances for controlling the Opening and
Closing of Valves.
I, BENJAMIN RHODES of 240 Bow Road, London, E. Engineer and Brassfounder,
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:-
My invention has for its object the better and more certain control of fluids or
liquids of different temperatures when being blended or mixed together so as to

geared into a pinion B which is fitted upon the spindle of one of the valves say the
valve controlling the colder fluid or liquid.
This segment of toothed wheel has attached to it a plate made of metal or other
suitable material F which forms part of the wheel segment. When both valve
spindles are shut down this plate or shutter covers the top of the spindle of the
valve controlling the hot liquid, and will continue to cover-samne until the valve
controlling the cold liquid is fully open, the metal plate or shutter will then be
moved quite clear of the spindle of valve controlling the hot liquid and this valve
can then be opened. When sufficient liquid or fluid has been drawn off, the valve
controlling the hot liquid must be shut down before the valve controlling the colder
liquid can be closed. Attached to the valves are standards D. D. to which is
fixed a plate made of metal or other suitable material E which covers the valves and
plate or shutter F and contains holes C. C. made to receive suitable key or keys
for opening and closing the valves.
This invention is applicable to screw down valves, more particularly to those made
in accordance with the inventions for which Letters Patent have been granted to me
bearing dates March 20th 1879 No. 1107 and February 6th 1888 No. 1755.
I wish it to be understood that I do not confine myself to the precise details or
modifications shewn in the accompanying sheet of drawings as the same may be
varied or modified without departing from the nature of my said invention and,
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
The employment of a sliding or moving plate or shutter made of metal or other
suitable material actuated by the valve that is required to be first opened and
controlling the orifice leading to the other valve or valves in a combination of two
or more valves for .controlling the flow of liquids of different temperatures or
natures and where it is of importance that one or more valves should be opened
before the other.
