IMPROVEMENTS IN APPARATUS FOR COLLECTING AND DIFFUSING HEAT
Year: 1885

page_text: I, THOMAS PICKUP of 43 Springfield road, Burnley, in the County of Lancaster,
Grocer, do hereby declare the nature of my said invention for "IMPROVEMENTS IN
APPARATUS FOR COLLECTING AND DIFFUSING HEAT," to be as follows:-
The object of this invention is designed to convey the surplus gases generated in
ordinary fire places, stoves, or kitchen ranges, into other rooms or apartments,
where heat is required.
For this purpose, I construct at the back of such fire place, Stove, or kitchen
range, a chamber having a perforated front or flap piece, which is so arranged as to
be readily removed for cleaning or other purposes.
In this chamber are collected
and utilized the surplus gases generated from the fuel under combustion. The
gases thus collected pass upwards through pipes or flues to a room or apartment
above, into a stove or receiver which may be of a cylindrical or other suitable form,
in which is placed a series of surface plates one above another, through which
the collected gases are led in a serpentine manner, so as to retain the heat
sufficiently in the "receiver" or stove, to ensure a proper diffusion of heat through
the outer casing of such receiver or stove into the room or apartinent, wherein
heat is intended to be distributed.
Suitable dampers are provided to regulate the flow of the gases into the receiver
or stove and their exit therefrom.

I, THOMAS PICKUP of 43, Springfield Road, Burnley, in the county of Lancaster,
Grocer, do hereby declare the nature of my invention for IMPROVEMENTS IN
APPARATUS FOR COLLECTING AND DIFFUSING HEAT," and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement:—
The object of this invention is to convey the surplus gases generated in ordinary
fireplaces, stoves, or kitchen-ranges into other rooms or apartments where heat is
required.
For this purpose, I construct, at the back of such fire-place, stove, or kitchen-
range, a chamber having a perforated front or flap piece, which is so arranged, as to
be readily removed for cleaning or other purposes. Into this chamber are collected
and utilized the surplus heated gases generated from, the fuel under combustion.
The gases, thus collected, pass upwards through pipes or flues to a rooin or apart-
ment above, into a stove or receiver, which may be of a cylindrical or other suitable
form, in which is placed a series of surface plates, one above another, through which
the collected gases are led in a serpentine manner, so as to retain the heat
sufficiently, in the receiver or stove, to ensure a proper diffusion of heat, through
the outer casing of such receiver or stove into the room or apartment wherein heat
is intended to be distributed.
And in order that my invention may be properly understood, and readily carried
into practical effect, I have hereunto attached the accompanying drawings, refer-
ence being had to the figures and letters marked thereon; the same letters
referring to the same parts in the various views and figures.
:
Figs. 1 and 2 are perspective views, representing respectively, a domestic stove
or kitchen-range, and a receiving and heat distributing apparatus, constructed in
accordance with my invention; Fig. 3 is an end section of Fig. 1; and Fig. 4, is a
similar view in section of Fig. 2, of which Fig. 5 is a longitudinal, and Fig. 6, an
horizontal section.
a, is a chamber situated at the back of the fire place b, and provided with.
openings or vertical spaces between the bars b₁, as shewn in dotted lines Fig. 1.
These openings or spaces are presented to the back portion of the fire, but,
sufficiently below the surface of such fire, that the heated gases evolved by
distillation will flow through the openings or slits into the chamber a, comparatively
free from smoke.
The heated gases circulating in the chamber a, produce an intense heat at the
back of the fire, which is diffused into the room by radiation. I am perfectly
aware that for this purpose, a perforated diaphragm has been employed, to divide
the lower part of the chimney flue into two portions, a front fire space, and a back
circulating space. The heated gases from the fire space divide themselves on each
side of the diaphragm, and immediately mingle with each other above the throat of
the chimney without any further utilization.
The primary object of this invention is to utilize the waste heat, by conveying
the gases collecting or circulating in the chamber a, through a pipe, channel, or

page_text: flue c, to an adjacent apartment, bath-room or greenhouse, in which the flue c may
be made to wind in a serpentine manner, and convey the heated gases in a tortuous
circuit before their return to the chimney m.
In most cases, I prefer for this purpose, a receiver constructed of metal, which
may be ornamented to any design, to suit the position or place it is intended to
occupy. The interior of the receiver is divided into three compartments f, g and h,
by surface plates d and e. The number of compartments may however, if desired,
be augment or diminished by the application of more or less surface plates.
The heated gases led or conducted by pipe c, as seen in Figs. 4 and 5 enter the
receiver, where, after traversing the lower compartment f, they pass upwards
through the opening d', and along the compartment G to the opening e¹, from
whence they are conveyed along the chamber h, to the exit pipe f¹ and chimney m.
The heated gases traversing through the compartments alternately as above
described, will impart an intense heat to the surface plates and side walls of the
apparatus, and ensure a regular transmission and conduction of heat into the
room.
The gases passing through the receiver, although collected as free as possible
from smoke, will carry into the receiver and deposite upon the surface plates,
Boot, which accumulating and being a non-conducting substance, would if not
removed, seriously obstruct the heating effect of the gases upon the surface plates
and side wall of the apparatus.
To clean the interior thoroughly of soot, which may from time to time accumulate,
I provide the doors J, as seen in Fig. 2, through which a brush, rake, or other
suitable instrument may be inserted.
I would here observe that a bell shaped mouth piece may be attached to the
pipe or flue c, in substitution of the collecting chamber a, and presented to the
back portion of the fire in like manner, and for the like purpose. I would also
remark that the front or perforated portion of the collecting chamber may be
movable between lugs cast to the said chamber, and being unattached, may be
shifted at pleasure to clear away soot or ashes which may accumulate.
A damper or valve k, seen in Fig. 3, may be used to regulate and control the
flow of heated gases into the receiver.
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, the collection and conduction of heated gases from a kitchen-range or other
suitable fire, into an adjoining apartment, bath room, or green house, substantially
as described and set forth.
Secondly, a loose or movable grate front for the chamber a, as described
and set forth.
Thirdly, the arrangement of apparatus represented in Figs. 2, 4, 5 and 6,
substantially as described and set forth.
