Improvements in Vertical-boilers.
We, ANTON PATZELT and ADOLF SCHÖCHE of 5 Seestrasse Dresden, in the
Kingdom of Saxony, Empire of Germany, Manufacturers, 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 subject of the invention in question is a vertical-boiler which may be used
to produce steam, as well as for the purpose of heating water. Owing to the peculiar
construction of this new boiler, a quick and abundant development of steam, a
rational use of the heating-gas and very little consumption of fuel, combined with
smokeless burning is attained. Besides this, in consequence of the simple manner
in which the single parts of the boiler can be taken asunder, it is always very easy
to effect the cleaning and revision of the boiler.
Referring to the drawing :-
-
;
Figure 1 shows a longitudinal section of the boiler on the line P-P of Fig. 2
Figure 2 a cross section, on the line - of Fig. 1; Fig. 3 a cross-section on the
line y-y of Fig. 1.
The construction is divided into 3 parts: a warming-boiler A, a seething-
boiler B and a steam-chest C. The warming-boiler A is represented by the outer
boiler-mantle a and an inner mantle ↳ running parallel to a, this inner mantle b
being connected by its under flange to the heating surface e, which bears the grate,
and by its upper flange to the flange of mantle a, which can be disconnected by
means of screws.
The seething-boiler B is hung centrally in the space formed by the boiler A and
consists of an outer mantle d closed towards the end by a concave bottom, and an
inner mantle which runs parallel to and is connected with it by flanges,
detachable by screws, which flanges at the same time form the upper end of the
boiler. In order to prevent the screw-knobs being destroyed by the fire-gases,
which come in contact with them, an appropriately formed cap can be fixed over
the top of the boiler B. The steam-chest C is placed above the two boilers A & B
and the fire passages. It consists of an outer mantle i and an inner mantle k; the
former is closed at the top by a cover g, while the lower end is screwed fast to the
bottom h, and the latter is connected by flanges to g and h which may be unloosened
by means of screws. The connection between the steam-chest C and the seething-
boiler B is made by three tubes 1, which are placed between the boiler-bottom h
and the top of the boiler B. In the same manner the heating-boiler A is connected
with the steam-chest C. The beating-tube fixed at the bottom of the seething-
boiler serves to connect the heating-boiler with the seething-boiler and makes it
possible at the same time, that the water circulates in all three boilers. Between
the flanges of the boiler-bottom hand the top of the heating-boiler A is fixed a
mantle-ring s made inside of a fireproof material and outside of iron-plate and
which, in order to make its removal easy, may consist of three or more parts. The
escape of the fire-gases is made possible in the space left by the inner boiler-mantles
in such a manner that a tube hung into the inner space of the boiler-mantle k and
reaching down to the space formed by the boiler-mantle e, represents the beginning
of the escape-pipe, the prolongation of which is at the same time the inner
boiler-mantle of the steam-collector C and a tube inserted into the former.
The fire-gases take the way marked out by the arrows, pass through the passage
formed by the mantles and d, playing strongly round the boiler-mantles and over
the top of the seething boiler, along the inner mantle-side and from there into the
escape-pipe. In this manner the fire comes in contact with the whole of the
mantle-sides and bottom and top of the seething-boiler, the inner side of the heating
21

latter. In order to facilitate cleaning and examination, the single boilers can be
taken asunder by loosening the connection-screws and so each boiler, owing to the
possibility of taking asunder the two mantles which form the boiler, can easily
be cleaned from within and freed from furs. The opening through the two
mautles of the warming boiler for the fire-door is arranged in such a manner as
not to prevent the taking out of the inner mantle . In order to sweep the fire-
passages, it is only necessary to take away the two escape-pipes o and » and the
mantle-rings, after which the passages can be easily and conveniently cleaned.

Having thus particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. A vertical circulation-boiler consisting of a heating boiler A of a circular
cross-section, in the inner space of which is centrally hung a seething-boiler B
with boiler-mantles shaped concave to the bottom while the steam-chest (C) is fixed
above these two boilers and is connected with them by tubes (I and m) whereby
the single interspaces between the three boilers (A, B and C) serve as draught-
passages for the fire-gases, which escape through an escape-pipe o passing through
the steam-chest (C) and reaching into the circularly shaped space formed by the
inner mantle of the seething-boiler (B) in such a manner that the fire-gases pass
along the whole surface of the inner mantle and bottom of the seething-boiler (B),
the surface of the inner mantle of the heating boiler (A) and the under surface
of the boiler-bottom of the steam-chest (C), substantially as herein described with
reference to the drawing.
2. A boiler (such as described under Claim 1) in which, in order to effect an
easy and convenient cleaning and revision, the single hoilers and their mantles
can be taken asunder, substantially as herein described with reference to the
drawing.
