page_text: I JOHN PETRIE of River Street Iron Works River Street Rochdale in the county
of Lancaster Machine Maker do hereby declare the nature of my invention for
IMPROVEMENTS IN APPARATUS FOR WARMING OR HEATING THE INTERIORS OF
ROOMS AND BUILDINGS and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
My invention relates to apparatus for warming or heating the interiors of rooms
or buildings by means of gas, oil, paraffin, or other suitable hydrocarbons, and
consists firstly in apparatus shown in Figs. and 2 of the drawings hereunto
annexed Fig. 1 being (an elevation in section and Fig. 2, a plan in section taken
on the line A. B, of Fig 1, similar letters of reference being applied to corresponding
parts in both of the figures-At a, is a vessel communicating by means of a pipe b,
with the outward flow pipe c, of any ordinary apparatus for heating the interiors
of rooms or buildings by means of hot water. The cylindrical part a¹, of the
vessel a, and the conical top a², thereof, and a portion of the pipe b, I surround by
a casing e, which casing e, is in communication with a pipe f-The return flow
pipe d, of the apparatus for heating the interiors of rooms or buildings above
referred to, is in communication with the pipe g, and the lower end of the pipe g,
is in communication with the interior of the vessel a-The interiors of the vessel a,
pipes b, c, d and g, I fill with water-The heat from the burner h, which, in this
instance is a burner for burning gas, acting upon the bottom a³, of the vessel a,
heats the water contained in such vessel a, thereby causing the said water when
heated to circulate along the pipes b, c, d, g, in the direction of the arrows C. D,
and from thence into the lower part of the vessel a, where it becomes again
heated, and is again caused to circulate through the pipes, b, c, d, and g as herein
before described.
The products of combustion from the burner h, pass from the bottom a³, of the
vessel a, and in the direction of the arrow E, along the space k, enclosed within the
casing e, and around the pipe b, from which space k, the said products of combustion
pass into the pipe f, to be conducted into any convenient flue or chimney-Upon
the pipe b, I fix a collar m, upon which rests a ring n, secured to the casing e, such
ring n, serving to support the casing e, and pipe f. The annular space o, above the
ring n, and between the pipe b, and the casing e, I fill with any suitable cement so
as to prevent the products of combustion passing along the casing e. and pipe f,
from escaping into the room or building which is to be warmed or heated-When
the water in the vessel a and pipes b, c, d and g,—becomes heated the heat
therefrom and the heat from the outer surfaces of the casing e, and pipe f, will
warm or heat the air in the interior of the room or building in which such apparatus
is placed.
At p, is a vessel or cistern the interior of which communicates by means of the
pipe g, with the pipe g, by means of which cistern p, water may be supplied to the
vessel a, and pipes b, c, d, and g.
By utilising the heat from the vessel a, pipes b, c, d and g, and the outer surfaces
of the casing e, and pipe f, I am enabled to warm or heat the interior of a room or
building without allowing any of the products of combustion from the burner h, to
escape into the interior of such room or building aforesaid.
Another arrangement of my invention is shown in Figs. 3 and 4.-Fig 3 being
an elevation in section and Fig. 4, a plan in section taken on the line F, G, of
Fig. 3—At r is a vessel to which is connected one end of a pipe s, the other end of

page_text: which pipe 8, is connected by means of a T piece t, with two pipes, uv, the
ends u, v, of which pipes u, v, communicate with an annular cavity w, formed
within the ring w¹, and are secured thereto by means of sockets w³, w, respectively
The ring w', is formed with flanges w², against the face of which an annular plate,
is secured by bolts or other convenient means-The annular plate x, is provided
with a number of sockets x¹, into each of which sockets x¹, is secured the upper end
of one of a number of vertical pipes y the lower end of each of which pipes y,
passes into one of a number of sockets z¹, formed upon an annular plate z, which
plate z, is secured by bolts, or other similar means to a plate, 1,-The plate 1, is
provided with an annular cavity 2-The annular spaces between the outsides of
the pipes y, and the sockets c¹, 21, into which such pipes y, pass, I fill with any
suitable cement for making a water tight joint-Upon the ring 1. are formed
sockets 3, 4, Secured to the socket 3, is one end of a pipe 5, the other end of which
pipe 5, is secured to the vessel r,-To the socket 4 is secured one end of a pipe 6,
the other end of which pipe 6, is secured to the vessel r.
The interiors of the annular cavity w, pipes u. v. vertical pipes s, y, annular
cavity 2, pipes 5, 6, and the interior of the vessel r, are all in communication with
each other.
At 7 is a burner which in this instance is a burner for burning gas, and is
supplied with gas by means of the pipe 8.-The vessel 7, pipes 5. 6. annular
cavity 2, vertical pipes y, annular cavity w, pipes, u, v, and vertical pipe s, are
filled with water supplied from a vessel 9, the interior of which communicates by
means of a pipe 10 with the interior of the vessel 7.- When the water in the
vessel, becomes heated by the heat from the burner 7, the water in the pipe 8,
will be caused to flow in the direction of the arrows H, along the pipes u, v, down
the vertical pipes y, and through the pipes 5, 6, into the vessel 7, and again to and
along the pipes, I surround the vessel r, with a casing 11, extending upward from
the top of which is a pipe 12, which pipe 12, surrounds a portion of the upright
pipe 8, Proceeding from the pipe 12 is a pipe 13-Upon the pipe 8, I fix a collar 14,
which supports the pipe 12, by means of a plate 15 secured to the pipe 12-The
products of combustion from the burner 7 are caused by the casing 11, and pipe 12,
to pass, after acting upon the vessel r, along the outside of the pipe 8, so as to heat
the water in such pipe 8, after passing along the outside of the pipe 8, the products
of combustion are conducted by the pipe 13, into any convenient flue or chimney-
The annular cavity above the plate 15, I fill with any suitable cement so as to
prevent the products of combustion which pass within and along the pipes 12, 13,
from escaping into the interior of the room or building within which the apparatus
above described is placed-As the heated water circulates through the vessel ?,
pipe 8, pipes u, v, cavity w, pipes y, annular cavity 2, and pipes 5, 6, the air
surrounding such parts will become heated and thereby warm or heat the air in
the interior of the room or building within which the apparatus above described is
situate.
The circular plate 1, is supported by means of a base 17; If desired the pipes y,
instead of being vertical may be inclined-The vessel 9, acts as a supply cistern by
means of which and the pipe 10. water may be supplied to the vessel ?, pipe 8,
pipes u, v, annular cavity w, pipes y, annular cavity 2, and pipes 5. 6.
At 18, is a pipe by means of which air or vapour may escape from the interior of
the vessel r, pipes u, v, cavity w, pipes y, cavity 2. and pipes 5, 6.-The water in
the vessel 9 also serves to impart moisture to the air contained within the interior
of the room or building within which the apparatus above described is situate-If
it be desired the pipes y, may be surrounded by a casing as indicated by the dotted
lines 19, such casing being provided with suitable perforations for the admission of
cold air and the escape of warmed or heated air.
Although I have hereinbefore described the various apparatus herein before
referred to as being heated by a burner which burns gas I would have it understood
that any other description of burner for burning oil, paraffin, or other suitable
hydrocarbon may be employed for heating the apparatus aforesaid I would also

page_text: have it understood that the vessels, a. 7, instead of being of the forms shown may
be of a spherical, cylindrical, or any other suitable form, and although I have
herein before described the apparatus as being arranged in a circular form, I would
have it understood that such apparatus may be arranged in any other form as may
be found desirable or convenient.
I would have it understood that I do not confine myself to the use of a single
circle of pipes y, as shown in Figs 4 and 5 but in cases where greater heating
surface is required I use two or more circles or rows of such pipes.
By causing the products of combustion from the burners h, 7, to pass along the
outer surfaces of a portion of the pipes b, 8, respectively, I am enabled to utilise a
large amount of the heat contained in such products of combustion for heating the
room or building within which the apparatus herein before described is placed,
which heat would otherwise be wasted.
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:-
Firstly Encasing the pipe b, Fig. 1, and pipe a, Fig 3. so that the heated products
of combustion from the burners h, 7, supplied with gas, oil, paraffin or other suitable
hydrocarbon, are kept in contact with such pipes b, 8, respectively for the purpose
of utilising the greater portion of the heat of such products of combustion
aforesaid.
Secondly The arrangements of apparatus constructed substantially as herein before
described and shown in reference to and in and by the drawings hereunto annexed
for the purposes herein before referred to.
