We RICHARD HOWSON of Southfield Terrace Middlesbrough on Tees in the County
of York Engineer, and WILLIAM PORRITT INGHAM of Queen's Square Middlesbrough
in the aforesaid County Engineer do hereby declare the nature of this invention to be
as follows:-
It has reference to letters patent heretofore granted to the above named Richard
Howson for an invention of an improvement in gas producers, such letters patent being
dated October 11th 1884 and numbered 13,467.
In the specification of the aforesaid invention the leading feature is that the current
of gas has a downward direction, & a particular arrangement is referred to in the
text and illustrated by the diagrams No. 7, 8, & 9. Now our invention consists in
reversing the current of gas while still retaining the general arrangement of parts
shewn in the said diagrams 7, 8, & 9 & referred to in the text of the aforesaid
specification.

page_text: We, RICHARD HOWSON, of Southfield Terrace Middlesbrough on Tees in the County
of York, Engineer, and WILLIAM PORRITT INGHAM of Queen Square Middlesbrough
aforesaid, Engineer do hereby declare the nature of our invention for AN IMPROVEMENT
IN GAS PRODUCERS and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
It has reference to letters patent heretofore granted to the above named Richard
Howson for an invention of an improvement in gas producers, such letters patent being
dated October 11th 1884 and numbered 13,467. In the specification of the aforesaid
invention the leading feature is that the current of gas has a downward direction, and
a particular arrangement is referred to in the text, and illustrated by the diagrams
Nos. 7, 8, and 9.
Now our invention consists in reversing the current of gas while still retaining the
general arrangement of parts shewn in the diagrams 7, 8, and 9, and referred to in
the text of the aforesaid specification.
In order to render the arrangement clear as applied to this invention, we have
annexed hereto two cross sections of a producer taken at right angles to each other.
It will be here seen that the working part of the apparatus consists of a chamber A
with a hopper B for feeding, at the top, and two cleaning out doors C C at the bottom.
These doors are opposite to each other and midway between them is a transverse
bridge D, the whole being so arranged that a bar can be passed entirely through the
chamber viz. in at one door, underneath the bridge, and out at the other door. In the
floor of the chamber and immediately beneath the bridge is a channel E which leads
to a chamber or flue F situated below, and into this chamber the air is blown by means
of the steam jet G and blow pipe H. The gaseous products pass through the
opening I in the usual manner. Having thus described the general arrangement of our
invention, we may state that parts thereof are capable of modification. For instance
an iron grate may be substituted for the channel E. Moreover the bridge D is shewn
as constructed of fire brick, but may be made in the form of a hollow cast iron box
into which the steam & air may be blown before it passes into the body of the fuel.
Having now particularly described and ascertained the nature of our invention, &
in what manner the same is to be performed, we declare that what we claim is the
arrangement described in a gas producer of two doors opposite to each other and
combined with a central bridge.
