Improvements in the Construction of Soot Boxes.
Year: 1886

page_text: I, HENRY SEALE, of 78 High Street, Tonbridge, Kent, Manufacturing Iron-
monger, do hereby declare the nature of this invention to be as follows:-
The object of this invention is firstly, to facilitate the fixing of the soot box-
and secondly, to render the same more convenient for use.
This I effect by making the edge round the mouth of the box plain instead of
with a flange as heretofore.
On the inner side of each side of the box I form a suitable curvilinear shoulder
while on the back of the box lid I cast two hooks so placed and formed that they
readily slip over and rest upon such shoulders.
I likewise cast a suitable thumb piece on the front of the box lid whereby it
can be easily lifted off or placed over the mouth of the box.
By dispensing with the flange as before mentioned much greater facility is
afforded for making the joints in the brickwork fit up accurately to the sides of
the box,
Improvements in the Construction of Soot Boxes.
I HENRY SEALE of Tonbridge Kent Iron and Brass Founder 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:—
The object of this invention is Firstly-To facilitate the fixing of the soot box-
and Secondly-To render the same more convenient for use by dispensing with
the ordinary hinged door and substituting therefor a suitable lid,

page_text: The letters of reference in the following description of my invention refer to
corresponding letters of reference in the accompanying drawings.
To effect this I make the edges round the mouth of the box plain instead of with
a flange as heretofore and form two suitable curvilinear shoulders a on the inside
of the box one on each side-I make the lid of the box of any convenient size and
shape while on the back of the box lid I cast or otherwise form thereon or affix
thereto two hooks or lugs b so placed that when the lid is placed over the mouth
of the box such hooks or lugs slip over and rest upon the two shoulders a thus
keeping the lid in position-I cast or otherwise form on or affix to the front of the
lid a suitable thumb piece c. or its equivalent so that such lid can be readily
removed or replaced as desired.
By this simple but highly effective method of securing the lid I dispense with
fastenings of any kind and obviate the trouble and difficulty now so frequently
experienced iu obtaining access to the flue of a boiler or chimney owing to the
hinges of the door being either choked with soot and dirt or corroded with rust
while by dispensing with a rim or flange round the edges of the mouth of a soot
box as above described-I greatly facilitate fitting a soot box in a flue or elsewhere
and also economise the cost and trouble of manufacture.
Fig. 1 of the accompanying drawings shews a view in front elevation of one of
my improved soot boxes with the lid removed to shew the plain edges A round the
mouth and the shoulders a.
Fig. 2 shews a view of the back lid with the hooks or lugs b.
Fig. 3 is a vertical section taken on the line D D Fig. 1 of the soot box when
closed shewing the thumb piece c on the front of the lid.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1. Making the edges of the mouth of a soot box plain substantially in the
manner and for the purposes hereinbefore described and shewn.
2. Fitting the mouth of a soot box with a lid substantially in the manner and
for the purposes hereinbefore described and shewn.
3. The improved construction of soot box herein before described and shewn at
Figs. 1. 2. 3 of the accompanying drawings.
