Elmonds, both of Brompton, in the County of Middlesex, for the
Invention of "IMPROVEMENTS IN APPARATUS FOR HEATING PIPES BY HOT.

Sealed the 7th August 1866, and dated the 10th February 1866.
PROVISIONAL SPECIFICATION left by the said George William Cumming
and John Kemp Edmonds at the Office of the Commissioners of Patents,
with their Petition, on the 10th February 1866.
We, GEORGE WILLIAM CUMMING and JOHN KEMP EDMONDS, both of
Brompton, in the County of Middlesex, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN APPARATUS FOR HEATING PIPES BY HOT
WATER," to be as follows:-
This Invention relates to certain improvements in the construction of
apparatus for heating pipes by hot water applicable to hot-houses, buildings,
and other purposes where water is circulated through such boilers by. means.
of a system of tubes or pipes. We propose to construct a boiler of the shape.
known as the saddle boiler by preference, but we also propose to use a:
common boiler or any hot water boiler suitable in shape and capable of adap-
tation for a flow or circulation of hot water. Such boiler or boilers is or are

page_text: to be enclosed or surrounded by a series of water tubes or pipes of a circular,
elliptical, or any other shape, such pipes or tubes being connected with the
boiler in order that the water may circulate through them. Pipes are also
brought into connection with the series of tubes and boiler for the purpose of
conveying the flow and return of hot water, and of transmitting such hot
water to the rooms of buildings or other places. The fire and heated pro-
ducts from the furnace pass around the boiler and tubes and rapidly heat
them. Over the boiler and tubes a horizontal smoke flue is formed in the
masonry, and communicates with the furnace by means of three or more
vertical flues, so that the heat may be drawn to all parts of the tubes and
boiler. Below the fire-bars chambers are formed for the entrance of cold
air to the ash-pit and thence between the bars.
SPECIFICATION io pursuance of the conditions of the Letters Patent, filed
by the said George William Cumming and John Kemp Edmonds
in the Great Seal Patent Office on the 10th August 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, GEORGE
WILLIAM CUMMING and JOHN KEMP EDMONDS, both of Brompton, in the
County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Tenth day of February, in the year of our Lord
One thousand eight hundred and sixty-six, in the twenty-ninth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said George William Cumming and John Kemp Edmonds, Her special
licence that we, the said George William Cumming and John Kemp
Edmonds, our executors, administrators, and assigns, or such others as we,
the said George William Cumming and John Kemp Edmonds, our executors,
administrators, and assigns, should at any time agree with, and no others,
from time to time and at all times thereafter during the term therein
expressed, should and lawfully might make, use, exercise, and vend, within
the United Kingdom of Great Britain and Ireland, the Channel Islands, and
Isle of Man, an Invention for "IMPROVEMENTS IN APPARATUS FOR HEATING
PIPES BY HOT WATER," upon the condition (amongst others) that we, the
said George William Cumming and John Kemp Edmonds, our executors or
administrators, by an instrument in writing under our, or their, or one of
their hands and seals, should particularly describe and ascertain the nature
of the said Invention, and in what manner the same was to be performed,

page_text: and cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said John Kemp Edmonds, do hereby declare
the nature of our said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following.
statement:-
This Invention relates to certain improvements in the construction of
boilers for heating pipes by hot water applicable to hot-houses, buildings, and
other purposes where water is circulated through such boilers by means of a
system of tubes or pipes.
We
propose to construct a boiler of the shape known as the saddle boiler
by preference, but we also propose to use a common boiler or any hot water
boiler suitable in shape and capable of adaptation for a flow or circulation of
hot water. Such boiler or boilers is or are to be enclosed or surrounded by a
series of water tubes or pipes of a circular, elliptical, or any other shape, such
pipes or tubes being connected with the boiler in order that the water may
circulate through them. Pipes are also brought into connection with the
series of tubes and boiler for the purpose of conveying the flow and return of
hot water and of transmitting such hot water to the rooms of buildings or
other places. The fire and heated, products from the furnace pass around the
boiler and tubes and rapidly heat thein. Over the boiler and tubes a
borizontal smoke flue is formed in the masonry, and communicates with the
furnace by means of three or more vertical flues, so that the heat may be
drawn to all parts of the tubes and boiler. Below the fire-bars chambers
are formed for the entrance of cold air to the ash-pit and thence between
the bars.
In the accompanying Drawings Fig. 1 is a transverse section of the boiler
and furnace; Fig. 2 being a longitudinal section; and Fig. 3 a plan view in
section. Similar letters denote corresponding parts in each of the Figures
respectively.
A represents the fire-place; B, the furnace bars; C, the ash-pit; D, D,
the fire space; E, the horizontal smoke flue; F, the connecting flues; G, the
flow pipe; H, the water tubes or boiler; I, the return water tubes; K, the
cold air chamber; L, the fire-bricks; the whole forming a cast-iron arrange-
ment of tubular arched saddle boiler for the purpose described. The
operation of the boiler will thus be readily understood by those conversant
with the construction of boilers for heating pipes by hot water applicable to
various useful purposes.

page_text: Having now described the nature of our said Invention, and the manner
in which the same is to be carried into effect, we would remark in conclusion
that we do not limit ourselves to the precise details and configuration of parts
we have expressed and shewn, as the same may obviously be slightly varied or
modified without in any way departing from the principles on which our
Invention is based, but what we claim and desire to be secured to us by the
herein in part recited Letters Patent are, the general arrangement, con-
struction, and combination of parts, substantially as herein specified and
shewn, constituting improvements in boilers or apparatus for heating pipes
by hot water....
In witness whereof, I, the said John Kemp Edmonds, have hereunto set
my hand and seal, this Ninth day of August, in the year of our Lord
One thousand eight hundred and sixty-six.
