IMPROVE- MENTS IN THE METHOD OF EMPLOYING WASTE STEAM AND THE WATER ARISING. FROM THE CONDENSATION THEREOF AND IN APPARATUS CONNECTED THEREWITH
Year: 1868

page_text: LETTERS PATENT to Samuel Burrows and Edwin Burrows, both of
Dukinfield, in the County of Chester, for the Invention of "IMPROVE-
MENTS IN THE METHOD OF EMPLOYING WASTE STEAM AND THE WATER ARISING.
FROM THE CONDENSATION THEREOF AND IN APPARATUS CONNECTED THEREWITH."
Sealed the 24th March 1868, and dated the 17th January 1868.
PROVISIONAL SPECIFICATION left by the said Samuel Burrows and
Edwin Burrows at the Office of the Commissioners of Patents, with
their Petition, on the 17th January 1868.
We, SAMUEL BURROWS and EDWIN BURROWS, both of Dukinfield,
in the County of Chester, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN THE METHOD OF EMPLOYING WASTE STEAM
AND THE WATER ARISING FROM THE CONDENSATION THEREOF AND IN APPARATUS
CONNECTED THEREWITH," to be as follows:-
Our Invention is designed for the purpose of returning to the boiler
the water accumulating in pipes from the condensation of steam
employed for heating mills or other large buildings so that it may be
again generated into steam, and the improvements consist in inserting or
applying through an aperture in the top of the boiler an inverted hollow
cone, a flange being formed at its base by which it is secured to the
boiler by a steam-tight joint, the lower end or apex of the cone
terminates in a small tube which dips in the water somewhat below its

page_text: lowest level, the upper end of the cone outside the boiler communicates
with the steam heating pipes, the internal diameter of which I prefer to
be small as the radiation of heat therefrom is much greater. These pipes
extend from the boiler in the ordinary manner through the mill, the
return or entrance into the boiler being effected by and terminating in
the cone, and the superior pressure arising from the column of water
in the cone allows it to be gradually received through the small tubes
into the boiler. By this means the water in the boiler is prevented from
becoming low during its disuse, and taps are provided for closing the
communication between the boiler and the pipes, and also a small plug
or tap is formed in the base of the cone in order that a clear passage may
be maintained through the same by occasionally passing a cleaning rod
through the same.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Samuel Burrows and Edwin Burrows in the Great
Seal Patent Office on the 16th July 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, SAMUEL
BURROWS and EDWIN BURROWS, both of Dukinfield, in the County of
Chester, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventeenth day of January, in the
year of our Lord One thousand eight hundred and sixty-eight, in the
thirty-first year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said Samuel Burrows and Edwin Burrows,
Her special license that we, the said Samuel Burrows and Edwin
Burrows, our executors, administrators, and assigns, or such others as
we, the said Samuel Burrows and Edwin Burrows, 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 THE METHOD
OF EMPLOYING WASTE STEAM AND THE WATER ARISING FROM THE CONDENSATION
THEREOF, AND IN THE APPARATUS CONNECTED THEREWITH," upon the condition
(amongst others) that we, the said Samuel Burrows and Edwin Burrows;

page_text: 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, 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 we, the said Samuel Burrows and Edwin
Burrows, do hereby declare the nature of the said Invention, and in
what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement, and accompanying
Drawings (that is to say) :-
:-
Our Invention is designed for the purpose of returning to the boiler
the water accumulating in pipes from the condensation of steam
employed for heating mills or other large buildings so that it may be
again generated into steam, and the improvements consist in inserting
or applying through an aperture in the top of the boiler an inverted
hollow cone, a flange being formed at its base by which it is secured
to the boiler by a steam-tight joint; the lower end of the cone terminates
in a small tube which may be elongated so as to dip in the water
somewhat below its lowest level, the upper end of the cone outside the
boiler communicates with the steam heating pipes, the internal diameter
of which we prefer to be small as the radiation of heat therefrom is:
much greater. The pipes extend from the boiler in the ordinary manner
but in a direct course through the mill, the return or entrance into the
boiler being effected by and terminating in the cone, and the superior
pressure arising from the column of water and steam in the pipes-
allows it to be gradually received through the small tube or cone into
the boiler.
In order that the Invention may be better understood and explained
in detail we have hereunto attached a Sheet of Drawings illustrative
of same.
Fig. 1 represents the vertical section of a mill in which an arrange-
ment of heating pipes are shewn passing from the boiler through the
various rooms or divisions of the mill, whence they return in a direct
course back again to the boiler. In this Figure a is the boiler employed
for heating the mill with steam by means of the pipes b which are so
arranged that the water accumulating from the condensation of steam
in such pipes will be conveyed back again into the boiler. In order

page_text: to introduce this water again to the boiler steam is allowed to pass into
the pipes through the tap c simultaneously with which the air tap d is
opened, which allows the air to be expelled therefrom, then the air tap
d is closed and the junction tap e opened, thereby opening a passage
for the water of condensation to the boiler, such return or entrance into
the boiler being effected by means of the cone f, the lower end of which
terminates in a small tube which dips in the water somewhat below
the level to which it ordinarily falls; by this means the superior pressure
arising from the bulk or column of condensed water in the pipes forces
the water through the cone or small tube into the boiler. The same
result may be also obtained by gradually reducing the internal diameter
of the pipes through which the water returns to the boiler or by the
interposition of plugs or taps to confine the area. The tap g is employed
for occasionally blowing off in order to maintain a clear passage into
the boiler. By this means the water in the boiler is prevented from
becoming low during its disuse, and taps may be provided in the heating
pipes for closing the communication between the boiler and any
particular room or compartment in the mill.
Having now described the nature of the said Invention together
with the method of carrying the same into practical effect, we wish it
to be distinctly understood that we claim the novel method of and
apparatus for returning to the boiler the water of condensation ac-
cumulating in pipes employed for heating purposes & through which
steam passes in a direct course from the boiler through the building
to be heated as herein-before described, set forth, and fully illustrated
in the Drawings attached.
In witness whereof, we, the said Samuel Burrows and Edwin
Burrows, have hereunto set our hands and seals, this Fifteenth
day of May, in the year of our Lord One thousand eight hundred
and sixty-eight.
Witness,
