PROVISIONAL SPECIFICATION.
Improvements in Boilers suitable for the Instantaneous Generation
of Steam.
I, WILLIAM HENRY NEWMAN, of Totteridge Park, in the County of Herts, do
bereby declare the nature of this invention to be as follows:-
According to this invention the boiler is built up of a number of rings of metal
bolted together.
Each ring has a shallow recess formed on one and preferably on both sides of it
so that on two rings being placed face to face a narrow passage is formed between
them, suitable holes being formed through the thickness of the rings to enable
the vapour to pass from one passage to the next.
The fire is placed within the rings and radial holes or passages are formed
through or between them to allow the heated products of combustion to pass
into an outer casing formed of non-conducting material and from thence to the
atmosphere.

COMPLETE SPECIFICATION.
Improvements in Boilers suitable for the Instantaneous Generation
of Steam.
I, WILLIAM HENRY NEWMAN, of Totteridge Park, in the County of Herts, 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:
According to this invention the boiler is built up of a number of rings of metal
bolted together.
Each ring has a shallow recess formed on one and preferably on both sides of it
so that on two rings being placed face to face a narrow passage is formed between
them, suitable holes being formed through the thickness of the rings to enable
the vapour to pass from one passage to the next.
The fire is placed within the rings and radial holes or passages are formed
through or between them to allow the heated products of combustion to pass
into an outer casing formed of non-conducting material and from thence to the
atmosphere.
Figures show a generator arranged for liquid fuel, the rings being held
ogether by bolts passing outside the generating rings and through strong clamp-

page_text: ing rings at top and bottom and being encased in air tubes lined with non-
conducting material to prevent them being overheated by the products of com-
bustion.
As an alternative method the bolts may pass through the generating rings, suit-
able means being taken to prevent them becoming overheated.
In a generator arranged for solid fuel a casing formed of non-conducting material
and containing a grate would be attached below the rings and the products of
combustion would pass up through the rings as before described.
AA are the generating rings, BB the passages for vapour, and CC the passages
leading the vapour through the rings from one passage B to the next.
The passages CC are placed alternately at opposite sides of the diameters of
consecutive rings so that the vapour has to circulate round the passages BB before
passing up through the ring into the next passage, DD are the bolts which pass
through strong clamping rings EE at top and bottom and also through the air
tubes FF lined with non-conducting material to prevent them being overheated
by the products of combustion, G G are the inlet and outlet for liquid and vapour
respectively, H shows the position of liquid fuel burner, KK are passages through
the rings to allow the products of combustion to pass into the space L formed by
the casing M and thence by the chimney N to the atmosphere.
Figures 2shew an enlarged section and plan of the rings. The joint between
the rings is formed as follows: one ring is formed with broad flat faces on each
edge of one side and the other with narrow V projections and a thin plate of soft
metal such as copper is placed between the two. When the rings are bolted
together the V projections slightly indent the soft metal and so form a metal
te metal joint.
The radial passages K for the products of combustion are formed by drilling
holes through the rings.
Figure 3 shows an alternative method of jointing the rings by forming them
with flat faces on each edge of both rings and using jointing material between the
two.
Figure 4 shows an alternative method of making the rings by casting them with
passages for the products of combustion, suitable connecting pieces being left at
intervals to support the upper and lower portions of the ring.
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. A boiler built up of a number of rings each having a shallow recess on one
or both sides substantially as described.
2. A boiler such as is referred to in claim 1 heated internally the products of
combustion escaping to the outside through passages in the rings substantially as
described.
3. Boilers substantially as described and shown in the drawings.
