PROVISIONAL SPECIFICATION.
Improvements in or connected with Tar Boilers.
I, JOSEPH CLAYTON, of the Firm of Clayton. Son and Company Limited,
Moor End Iron Works, Hunslet, Leeds, in the County of York, Gas Holder
and Boiler Makers, do hereby declare the nature of this invention to be as
follows:-
The object of my invention is to construct boilers for heating tar, pitch, and
like substances, in such a manner that the detrimental effect of boiling over is
prevented, whilst at the same time greater economy is effected than when boilers
as hitherto constructed are employed.
According to my invention I construct the boiler in two sections, each section
being provided with a separate furnace for heating same. The two sections are
separated from cach other by a partition, which extends the full length of the
apparatus and rises in height to within a short distance of the cover. This
partition is constructed in a hollow form, which enables it to serve the purpose of
a central flue, one of its ends being connected with the boiler chimney.
The furnaces, which are situated beneath their respective sections, run the full
length of same; and at the end of the apparatus, the said furnaces communicate
with jacket flues, which latter are situated at the sides of the boiler and continue
round the front, where they connect with the central flue formed by the partition.
A deflector is provided at the junction of the side flues with the central fluc,
for the purpose of directing the draught toward the chimney.
Each section is fitted with a door for the insertion of the tar to be heated,
suitable catches being provided to hold the doors open when required; and taps
or other openings are connected with each section for the purpose of drawing off
the contents.
When the apparatus is in use, the contents of one section may be boiling whilst
the other section is being prepared, thus enabling the apparatus to be kept in
constant use and preventing the continual delays in working hitherto experienced.
Should one of the sections boil over, the superfluous material flows over the
partition into the other section, instead of flowing over the side of the apparatus
and being wasted.
The construction of jacket flues completely encases the sections, thereby utilizing
the heat from the furnaces to the utmost extent, and effecting a considerable saving
in fuel.

I, JOSEPH CLAYTON, of the Firm of Clayton, Son and Company Limited,
Moor End Iron Works, Hunslet, Leeds, in the County of York, Gas Holder and
Boiler Makers, do hereby declare the nature of this invention and in what manner
[Price 8d.1

page_text: the same is to be performed, to be particularly described and ascertained in and by
the following statement :-
The object of my invention, is to construct boilers for heating tar, pitch, and
like substances, in such a manner that the detrimental effect, of boiling over is
prevented, whilst at the same time greater economy is effected than when boilers
as hitherto constructed are employed.
In order that my invention may be clearly understood, I will proceed to describe
same with reference to the accompanying drawings, in which similar letters refer
to like parts in all the figures.
Fig. 1 is side elevation, Fig. 2 is an end elevation, Fig. 3 is a sectional plan on
line X, X Fig. 1, and Fig. 4 is a transverse section on line Y, Y Fig. 1, of a tar
boiler constructed according to my invention.
The boiler is constructed in two sections A and B, and each section is provided
with separate furnaces C and D for heating same. E is a partition, which divides
the sections A and B from each other, and the said partition E is of hollow form
which enables it to serve the purpose of a central Hue, one of its ends being in
connection with a chimney F. The ends of the furnaces C and D, communicate
through passages G and H with jacket flues J and K, the latter continuing round
the sides and front of the boiler and connecting with the central flue or partition E.
L is a deflector for the purpose of directing the draught from the flues J and K
through the partition E towards the chimney F. M and N are doors for the
insertion of the tar into the sections A and B, and P and R are catches for holding
the doors open when required. Suitable taps are provided for the purpose of
drawing off the contents when required.
When the apparatus is in use, the contents of one section may be boiling whilst
the other section is being prepared, thus enabling the apparatus to be kept in
constant use and preventing the continual delays in working hitherto experienced.
Should one of the sections boil over, the partition E being lower than the sides of
the apparatus, the superfluous material flows over the said partition into the other
section, instead of flowing over the side of the apparatus and being wasted as bas
hitherto been the case. It will thus be seen that the flue E and jacket flues J
and K, completely encase the sections, thereby utilizing the heat from the furnaces
to the best advantage, and effecting a considerable saving in fuel.
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. The boiler composed of two sections A and B, divided by the partition E
substantially as and for the purposes set forth.
2. The boiler composed of sections A and B having furnaces C and D below
same, the said furnaces communicating with the jacket Hues J and K through the
passages G and H, the said flues connecting with a central flue E, substantially as
aud for the purposes set forth.
3. A tar boiler, composed of the sections A and B, furnaces C and D, hollow
partition E, chimney F, passages G and H, jacket flues J and K, deflector L, and
suitable doors and taps, substantially as and for the purposes set forth, together
with any mere modification or modifications thereof.
