Improvements in Controlling Gear for Steam Supply to Water Gas
Generators.
I SAMUEL CUTLER, of Providence Iron Works, Millwall, in the County of London,
Engineer, do hereby declare the nature of this invention to be as follows"
--
This invention relates to mechanism for controlling the steam supply to water gas
generators and consists in a novel method of actuating the steam admission cocks
simultaneously with the gas outlet valves in such a manner that steam cannot be
admitted to the generator if the corresponding gas outlet valve is closed.
There are several types of water gas generators in use and this invention applies
particularly to those having either one steam admission and one gas outlet or two
steam admissions and two gas outlets. In the case of the latter type of generator
this invention is equally applicable where the gas outlet valves are worked singly or
where they are coupled to work simultaneously. In the case of two gas outlet valves
worked singly my invention also prevents any steam being admitted to the generator
if by error in working both of the gas outlets are either open or closed.
In carrying out my invention I place upon the pinion shaft of the gas outlet
valve, or other shaft actuated by the movement of this valve, a bevel or other gear
wheel and fix in connection therewith a series of quadrants and levers by means of
which one or more single way cocks are actuated simultaneously with the opening or
closing of the gas valve.
Where the generator has one steam admission, and one gas outlet, I use one single
way steam cock. Where the generator has two steam admissions and two gas outlets,
and the gas valves are coupled to move simultaneously, I use two single way steam
cocks; and where the generator has two steam admissions and two gas outlets, and
the gas valves are worked singly, I use 4 single way steam cocks.

Generators.
I SAMUEL CUTLER, of Providence Iron Works, Millwall, in the County of London,
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 mechanism for controlling the steam supply to water gas
generators and consists in a novel method of actuating the steam admission cocks
simultaneously with the gas outlet valves in such a manner that steam cannot be
admitted to the generator if the corresponding gas outlet valve is closed
My said invention is particularly applicable for those water gas generators which
have two steam admissions and two gas outlets, but is equally applicable where the
ID 11

page_text: gas valves are worked singly or where they are coupled together. In the former case
my invention also prevents steam being admitted to the generator if by any error
both the gas valves are either open or shut.
In carrying out my invention I connect some moving part of the gas outlet
valves by means of suitable gearing to a number of single way steam cocks and thus
actuate them simultaneously with the gas valve. Where the generator has its two
outlet valves worked singly I actuate two single way steam cocks from each valve,
and where the gas outlet valves are coupled I actuate one single way steam cock from
each valve or, alternatively, two cocks from either valve.
The accompanying drawing shows in elevation one method of applying my
invention.
A water gas generator X has two gas outlets controlled by valves A and B and
two steam admissions W and W₁ controlled by steam cocks H and H¹. The valves
are worked singly by suitable gearing and are of the "outside rack and pinion
type. To the rack of each valve I connect a lever C pivoted on a fulcrum D and
connected to a rod E which is free to rise and fall in the guides G. Upon this rod
I provide pivots for slotted levers F and F¹ which are attached to the steam admission
cocks H and H. The levers F and F are set in such a manner that when the upper
gas valve A is opened, the upper steam cock H' is closed and the lower one H is
opened. By a corresponding set of gear connected to the valve B a lower steam
cock is closed and an upper steam cock is opened simultaneously with the opening of
the said valve B. This second set of gear is preferably placed on the reverse side of
the valves so that only one set is seen in the drawing annexed but both sets of gear
are similar in all respects.
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. In combination with a water gas generator an arrangement of mechanism
substantially as herein before described by means of which a number of single way
steam admission cocks are actuated simultaneously with the opening or closing of the
gas outlet valves.
2. The arrangement and construction of gear for controlling the supply of steam
to water gas generators substantially as hereinbefore described and shown on the
drawing.
