FREDERICK WILLIAM ASHFORD 68 Ambler Road Finsbury Park London N.
Pianoforte Maker. I, Frederick William Ashford do hereby declare the nature of
this invention to be as follows:-
An improvement in apparatuses for heating greenhouses baths and the like with
gas or oil.
1:
The novelty or invention consisting in a number of casings (B. C. D and E to
wit) so arranged as to form two complete boilers connected by various tubes A ;
the heat passing up between B. filling the space between C and D with heat untill
it gets down to 1, when escapes by means of chimney J, thus doubly heating the
contents of the apparatus with the same flame or heating medium.

An Apparatus for Heating Greenhouses, Baths, and the like.
FREDERICK WILLIAM ASHFORD 68 Ambler Road Finsbury Park London N.
Pianoforte Maker 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 :-
That this apparatus or invention consists of a number of casings or cham-
bers B, C, D, and E, arranged in the manner hereinafter described so as to form a
complete boiler.
Figure 1. in the accompanying drawings is a vertical section of the apparatus
taken at the line F F shown on Figures 2 and 3.
Figure 2. is a horizontal section taken at G G Figure 1.
Figure 3. is a horizontal section taken at H H Figure 1.
Figure 4. is a perspective view of the inner boiler showing the arrangement of the
tubes A.
Figure 4 is a perspective view of the inner boiler in duplicate form for two
burners.
Figure 5. is a perspective view of the complete apparatus showing the arrange-
ment of the heating medium.
The apparatus should be constructed of copper or some other suitable metal.
The inner boiler or chamber Figure 4 is cylindrical in form and is provided with a
vertial flue B in the centre through which the flame passes. On the top or upper
surface of this chamber a number of perforations are made as shown in Figure 2,
and the small tubes, A, Figure 4, affixed. A perforation is also made in the centre
of this upper surface for the flue B, the lower end of this chamber, above the burner O
Figure 1, is in the form shown in Figure 3 between B and C-the inlet socket N
is attached to this inner boiler or chamber as shown in Figure 1.
The outer boiler, E Figures 1, 2, and 3 is a casing of copper or other metal
enclosing the inner boiler, and is the entire size of the apparatus. This outer
casing E Figures 1. 2 and 3 has an inner casing D Figures 1 and 2 and Da Figure 1,
Di

page_text: fitted to the upper portion only. The plate Dª has perforations similar to those in
the upper surface of the inner boiler for the smaller tubes A to be fitted-by which
means the inner and outer boilers are thus connected and the outlet socket M
Figure 1 is fitted thereto, making a complete boiler.
The water enters the inner boiler at N and circulates through both boilers and
escapes at M.
In the lower half of the outer casing E is an aperture I Figure 1, which is
provided with a down or back draught excluder K, this latter consists of a semi
cone shaped piece of metal affixed above the aperture I. To the outer boiler the
chimney J Figure 1 is fitted being of a semi tubular form, until the top of the boiler
is reached when its form is tubular as in Figure 5. The flame therefore passes up
the flue B heating the space or spaces between the tubes A, and C and D and
travels down to the aperture I when it escapes by means of the chimney J.
At the base of the apparatus is fitted a tray or cap L Figure 1, to receive the
moisture or condensed vapour caused by the flame coming in contact with the
cooler surface of the boiler, it is then discharged through the opening P into
the gutter R Figure 5, this is fixed to the stand upon which the apparatus is
mounted. The tray or cap L has also an opening in the centre for the flame to pass
up the flue and it is so made that it may be removed or separated from the boiler so
that the flue may be easily cleaned when required.
The gas or oil burner is fitted or placed on the stand underneath the flue.
Two or more vertical flues B may be inserted in the inner boiler and connected
as shown in Figure 4^ according to the power required.
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. That the complete boiler is so constructed as to present the greatest amount
of surface to be heated, by the formation of the flue or flues. Also by the heat
having to pass up the vertical flue B₁ to the top of the inside of the boiler and
brought into direct contact with the plate Da tubes A. and casing D, in which
chamber it is stored, it being unable to escape until it is exhausted owing to the
position or situation of the aperture I in the casing E.
2. The complete apparatus constructed and operating substantially in the manner
and for the purpose described and illustrated in the accompanying drawings.
Dated this 25th day of August 1892.
FREDERICK WILLIAM ASHFORD.
