page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
Matthew Allen, do hereby declare the nature of my said Invention, and in
what manner the same is to be performed, to be fully described and set forth
in and by the following statement and Specification thereof, reference being
had to the accompanying Drawings, which I declare to belong to and to form
part of such Specification, by the letters and numeral figures marked thereon
for the purpose of such reference, that is to say:--
The nature of my said Invention consists in and has reference to certain
improvements in stoves and apparatus for heating, and I declare the particular
manner in which the same is to be performed and carried into practical effect
to be and to consist in the construction and the arrangement of mechanical
parts, together with the combinations of such parts with and amongst cach
other, devised for and applied to the herein-before said purposes, as the same
are herein-after described and set forth, that is to say-The Figure 1 of
the Drawing No 1 shews a view in front elevation of the arrangement or appa-
ratus, comprising a stove or apparatus for heating in an economical and
efficacious manner, with the particular construction of the mechanical parts
of the same, together with the distribution and arrangement of such parts with
respect to each other, and also as regards the entire combination or compound
of the said stove or apparatus, the several mechanical parts composing the said
apparatus being repeated in the different sectional views in the Figures of
the Drawings according to the known practice of mechanical draftsmen for
the instruction of workmen in the fabrication of the objects of such Drawings.

sents a separate view in external elevation of the portion A, A, A, A, A
of the Figure 2 of Drawing N° 1, its lower portion X, Y, (in this Figure 3 of

page_text: the Drawing No 2,) being shewn as laid open in a sectional view in order to
expose to view and explain its internal construction. The Figure 4 of the
Drawing No 2 represents a separate horizontal plan view of the portion B, B,
of the Figure 2 of the Drawing No 1. The Figure 5 of the Drawing No 2
represents a corresponding separate vertical section of the portion B, B, imme-
diately above referred to. The Figure 6 of the Drawing No 2 represents a
separate end view in elevation of the same portion B, B. The Figures 7 and 8
of the Drawing No respectively represent views in vertical section and in
external elevation of a heating saucepan or vessel, which is herein-after more
particularly described. The Figure 7 of the Drawing No 1 is a view in eleva-
tion of a cleansing brush or machine for the portion W, W, of the Figure 2 of
the Drawing No 1, and marked at w, w, w, w, of that portion W, W.
In each of the Figures 1, 2, 3, 4, 5, and 6, of the Drawing No 1, and also
in each of the Figures 1, 2, 3, 4, 5, and 6, of the Drawing No 2, the same
parts of the apparatus are respectively marked with the same letters of refer-
ence, in so far as such several parts can be shewn in each of such Figures. In
the Figures 1 of the Drawing No 1 the entire Figure shews the complete
elevation of the apparatus; the line A, A, drawn vertically through the Figure
marks the place and the direction in which the vertical section shewn in the
Figure 2 is taken; the line B, B, drawn horizontally through the Figure
marks the place and the direction in which the horizontal section shown in the
Figure 3 is taken; the line C, C, drawn horizontally through the Figure marks
the place and the direction in which the horizontal section shown in the
Figure 4 is taken; the line D, D, drawn horizontally through the Figure
marks the place and the direction in which the horizontal section shown in the
Figure 5 is taken; the line E, E, drawn horizontally through the Figure
marks the place and the direction in which the horizontal section shewn in
the Figure 1 of Drawing No 2 is taken.
The internal construction of the apparatus is shewn in the Figure 2 of the
Drawing No 1. A is the fire-place; a, i, the fire bars; B, B, a sliding
drawer, serving the purpose of the usual ash pit of a furnace or fire-place,
to which the air necessary to support combustion is supplied in the usual
manner, through or by the bottom of the ash drawer or by its front; upon the
roof of the fire-place F, F, are placed vertical chambers or flues, of which
two are shewn at C, C, the whole number of such chambers in the arrange-
ment of the Drawing being three; the smoke and heat generated in the fire-
place is thus communicated and passes into the chambers C, C, where it is
economised as regards the expenditure of heat by its retention within the wind-
ing passages formed by the helical course of the plates W, W, cach revolution

page_text: of which occupies the entire horizontal and sectional area of the chamber c, c;
smoke and heat also passes off by a direct passage through the pipe or flue
F, F, the exit of which is regulated by a damper f; the smoke and heat so
delivered by this flue and by the helical flues before described is discharged
through the passage g, and after circulating through the helical passages h, h,
of the top upper portion K of the stove, passes off through the chimney dis-
charge pipe H, H. In the arrangement shewn in the Drawings, four vertical
chambers or flues are shewn, three of which are occupied by the helical passages
before mentioned, and the fourth is occupied by a central boiler E, which passes
vertically through the centre of the chamber C, C, and is surrounded by an
annular chamber e, e, e, e, leaving a second annular passage n, n, n, n, between
the chambers e, e, e, c, and the central boiler E; the central boiler E and the
annular chamber c, c, e, e, are both occupied by the water which is to be heated;
the annular passage n, m, n, n, is a flue for heated air and smoke by which the
necessary heat is communicated to the boilers; the passage D, which forms
the axis and passes through the centre of the helical passage before mentioned,
is continued downwards to D*, where it opens to the outer air, the uninter-
rupted stream of which is heated during its passage through the length of the
helical passage, and is given out at its upper termination D**, to the apart-
I is the furnace or fire-place door. E, E, E, is a pipe passing between
the back of the ash drawer B, B, and runs upwards, as shewn in the Draw-
ing, passing through the chimney pipe H, H, to gas burners at G, supplied by
gas pipes F, F, from the usual sources; such downward current of air as may
be generated by the rarefaction of the air supplied to and through the gas
shade and the tube E, E, will be led to or suffered to enter the ash drawer
B, B, and so pass thence under and through the fire bars a, a, of the fire-
place. The brush V, V, with the helical wire stem w, w, w, w, is used to cleanse
the helical passages of the chambers C, C, before mentioned.
ment.
The Figure 7 of the Drawing No 2 shews a view in vertical section of the
saucepan or heating vessel before mentioned, in which S is a conically formed
body, and having a concave bottom T, and is placed within an outer vessel S*,
which is of the usual cylindrical form; the Figure 8 shews an external eleva-
tion of this utensil.
Having thus described the nature and intention of my said Invention, and
also in what manner the same is to be ascertained and performed, I now de-
clare that I claim as of my Invention the particular modes of arrangement, and
the particular combinations of parts, together with the principles of construction
upon and according to which such particular modes of arrangement and such
particular combinations of parts are made, and by which the same are carried

page_text: into practical effect, such the modes of arrangement, combinations of parts,
and principles of construction being in the manner as I have herein-before
specified, described, and set them forth.
In witness whereof, I, the said Matthew Allen, have hereunto set my
hand and seal, this Thirtieth day of July, in the year of our Lord One
thousand eight hundred and forty-five.
