Improvements in Vertical Steam Boilers.
I, JOHN PARTINGTON, of Water Lane Boiler Works, Thornton Road, Bradford,
in the County of York, Boilermaker, do hereby declare the nature of this inven
tion, and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
In my improved boiler I so construct the furnace that it can be easily removed
and replaced, or renewed.
To attain this object, I make a conical shaped furnace, flanged outwardly at the
largest end, the other end being closed with a circular shaped plate, leaving a
sufficient water space between this and the outer shell of the boiler. At the
smaller end, there is a branch on the top side, with a flange, which is bolted on to
a similarly flanged branch, which is connected to a circular plate running
horizontally and forming the bottom tube plate, the tubes, which may be expanded
riveted, welded, or screwed into the tube plates, running vertically, with a corre-
ponding tube plate at the top end of the tubes.
These two tube plates are attached to one another at a given distance by means
of plates running round the edges of the tube plates, the latter being flanged to
receive same. The cylinder thus formed is of rather smaller diameter than the
inside diameter of the boiler, thus allowing sufficient water space, and a smokebox
or outlet passes by a branch from this inner cylinder to the outer shell, to which it
is connected.
In the centre of the two tube plates there is a tube, or pipe, running vertically,
and riveted or welded at each end to the tube plates, forming a stay, and also
serving to assist the circulation and to give heating surface.
The water in my improved boiler is inside the vertical tubes and the heat
passes in amongst the tubes, round the centre tube, and into the smokebox.
When the furnace is required to be withdrawn, either for cleaning purposes or
for renewal, all that it is necessary to do, is to disconnect the two branches which
are bolted together inside the boiler, and unscrew the nuts round the furnace
front.
The bottom of my improved vertical boiler I make hollow, or dish shaped, with
a blow off branch from the bottom of same. In this class of boiler there are no
corners or small spaces left for deposit.
In the drawings annexed
Fig. 1. shows a sectional view of my improved vertical boiler, A. is the removable
cone shaped furnace, with a branch B. at the end. the largest end being flanged
outwardly, as shown at M. for bolting against a branch N, which is attached to the
outer shell H. C. is the branch which is connected to the bottom tube plate D.
E. is the top tube plate, F. is the cylinder, or plates joined on to the outer edges
of the two tube plates D. and E. G. is the opening from the cylinder plate F.
connected on to the shell of the boiler H. leading into the smoke box. I. is the
tube which is riveted to the centre of the top and bottom tube plates. The tubes
running vertically are shown J. the water being inside and the heat outside. K. is
the dish shaped bottom with the blow off L.
Fig. 2. shows a section through the middle of the tubes, the opening C. being
the position of the branch C. in Fig. 1. 1. is the tube shown I. Fig. 1. G. is
the opening into the smoke-box shown G. Fig. 1. which is nearer or at the side
of the pipe C. By the side of this pipe and across the tubes filling up the space
between E. and D. Fig. 1. I have a baffle plate of fire brick or of sheet asbestos.
By this means the fire is taken or driven round the outside of the tubes to the

page_text: right or to the left according to the position of the smoke box, or the smoke box
can be placed as shown in Fig. 1. the centre pipe I. stopping the heat.
Fig. 3. shows a front view of the removable cone shaped furnace A. Fig. 1. with
the bolts running round the flange M. Fig. 1.
Having now particularly described and ascertained the nature of my inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
1. The improved vertical steam boiler substantially as described and shown in
drawings.
2. In vertical steam boilers the use of a removable furnace substantially as
described and shown in drawings.
3. In vertical steam boilers with a removable furnace the position of the tube
plates and tubes substantially as described and shown in drawings.
4. In vertical steam boilers with a removable furnace the method of connecting
the two tube plates by a centre tube or pipe substantially as described and shown
in drawings.
5. In vertical steam boilers with a removable furnace, the use of a dish shaped
bottom substantially as described and shown in drawings.
6. In vertical steam boilers with a removable furnace the use of a baffle
plate for distributing the heat round the tubes substantially as described.
