Year: 1871

page_text: LETTERS PATENT to Frederick John Mee, of Liverpool, in the County
of Lancaster, for the Invention of "IMPROVEMENTS APPLICABLE ΤΟ
SADDLE AND OTHER BOILERS FOR HOT WATER APPARATUS FOR HEATING
HORTICULTURAL AND OTHER BUILDINGS."
Scaled the 4th August 1871, and dated the 6th February 1871.
PROVISIONAL SPECIFICATION left by the said Frederick John Mee
at the Office of the Commissioners of Patents, with his Petition,
on the 6th February 1871.
I, FREDERICK JOHN MEE, of Liverpool, in the County of Lancaster,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
APPLICABLE TO SADDLE AND OTHER BOILERS FOR HOT WATER APPARATUS FOR
HEATING HORTICULTURAL AND OTHER BUILDINGS," to be as follows (that is to
say)
This Invention relates to certain improvements which are applicable
to the boilers of hot water apparatus, and peculiarly to the description

page_text: known as saddle boilers used for heating horticultural and other
structures, whereby a large additional amount of heating surface is
obtained, and a perfect circulation of the water throughout the apparatus
is ensured.
The improvements consist of a rectangular water space, the top of
which forms the dead plate of the furnace, connected by hollow bars
with a suitably shaped water space, which forms the back of the fire-
grate and a portion of the top or crown of the furnace, and in some
cases it is extended below so as to form a bed in the rear of the bars,
the water space being so constructed that there is an opening or flue
passage between the rear end of the boiler and the vertical face of the
water space.
In applying this Invention to say a saddle boiler, the horizontal hollow
bars at one end open into the water chamber or box, the top of which
forms the dead plate, and at the other into the water space forming the
back of the furnace. The water space within the rectangular box or
chamber in front of the furnace and the hollow bars and water space in
the rear thereof, are connected by a double branch connecting pipe
attached to a flange on the top of the return of the hollow chamber
forming the back and a portion of the crown of the arch of the furnace and
at the other to a flange pipe on the top of the saddle boiler near the rear
thereof, this double branch connecting pipe connected with the ordinary
flow pipe and a second double branch connecting pipe is used for the
return, one end of which is connected to one side of the front of the
saddle boiler near the bottom, and by the other leg to the chamber or
water space in front of the furnace, thus forming a bed for the saddle
boiler, which latter it is preferred should be formed from wrought-iron
with welded joints. The boiler and its attachments are set in brickwork
in the ordinary manner, the products of combustion being split at the
back of the furnace and carried back along the sides and over the top of
the boiler to the take up of the chimney. In some cases the hollow bars
with their back and front water spaces may be fitted with independant
return and flow pipe arrangement, so that the same may be used
independantly or separately from the saddle or other boiler, that is to
say, it may be arranged as a double independant heating apparatus
heated by a furnace.
These improvements may be added to any of the ordinary boilers now

page_text: in use by removing the ordinary bars and brickwork at the back of the
furnace and substituting therefor the hollow bars with their end
chambers.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Frederick John Mee in the Great Seal Patent
Office on the 5th August 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FREDERICK
JOHN MEE, of Liverpool, in the County of Lancaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Sixth day of February, in the year of
our Lord One thousand eight hundred and seventy-one, in the thirty-
fourth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Frederick John Mee, Her special
license that I, the said Frederick John Mee, my executors, adminis-
trators, 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 APPLICABLE
TO SADDLE AND OTHER BOILERS FOR HOT WATER APPARATUS FOR HEATING
HORTICULTURAL AND OTHER BUILDINGS," upon the condition (amongst others)
that I, the said Frederick John Mee, my executors or administrators,
by an instrument in writing under my, 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 I, the said Frederick John Mee, do hereby
declare the nature of my said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained in
and by the following statement in writing, reference being had to the
accompanying Drawings, and to the letters and figures marked thereon,
that is to say :-

page_text: This my said Invention relates to certain improvements which are
applicable to the boilers of hot water apparatus and peculiarly to the
description known as saddle boilers used for heating horticultural and
other structures, whereby a large additional amount of heating surface
is obtained and a perfect circulation of the water throughout the
apparatus is ensured.
My said improvements consist of a rectangular water space, the top
of which forms the dead plate of the furnace, connected by hollow bars
with a suitably shaped water space, which forms the back of the firc
grate and a portion of the top or crown of the furnace, and in some
cases I extended it below so as to form a bed in the rear of the bars.
This water space I so construct that there is an opening or flue passage
between the rear end of the boiler and the vertical face of the water
space.
In applying this my said Invention to, say, a saddle boiler, the hori-
zontal hollow bars at one end open into the water chamber or box, the
top of which forms the dead plate, and at the other into the water space
forming the back of the furnace. The water space within the rectangular
box or chamber in front of the furnace, the hollow bars and water space
in the rear thereof, I connect by a double branch or connecting breeches
pipe attached to a flange on the top of the return of the hollow chamber
forming the back and a portion of the crown of the arch of the furnace,
and at the other to a flange pipe on the top of the saddle boiler near
the rear thereof. This double branch syphon is connected with the
ordinary flow pipe, and a second double branch syphon or breeches
pipe is used for the return, one end of which is connected to one side
of the front of the saddle boiler near the bottom, and by the other leg
to the chamber or water space in front of the furnace, thus forming a
bed for the saddle boiler, which latter it is preferred should be formed
from wrought iron with welded joints. The boiler and its attachments
I set in brickwork in the ordinary manner, the products of combustion
being split at the back of the furnace and carried back along the sides
and over the top of the boiler to the take up of the chimney.
In some cases the hollow bars with their back and front water spaces
may be fitted with independent return and flow pipe arrangement, so that
the same may be used independantly or seperating from the saddle or

page_text: other boiler, that is to say, it may be arranged as a double independant
heating apparatus heated by one furnace.
These my said improvements may be added to any of the ordinary
boilers now in use by removing the ordinary bars and brickwork at
the back of the furnace and substituting therefore the hollow bars with
their end chambers as described.
That this my said Invention may be the more readily seen and under-
stood I have hereunto annexed Drawings in illustration of the same,
and showing its practical application to a common saddle boiler. Like
letters and figures marked on the Drawings being used to indicate
similar parts.
Figure 1 is a side clevation of one of my improved water heating
apparatus; and Figure 2 is a top view or plan of the same; Figure 3
is a transverse vertical section of one of my improved heaters in com-
bustion with a common saddle boiler with the brickwork and flues;
and Figure 4 is a longitudinal vertical section of my improved water
heater. The position a saddle boiler would occupy when used therewith
being indicated by the dotted lines.
A, rectangular chamber forming the dead plate of the furnace formed
with B, an inlet or return pipe; C, chamber forming the vertical back
of the furnace and a portion of the back of the furnace bed, also a part
of the rear end of the crown of the furnace and which is provided on
the top with D, a junction for the pipe through which the heated water
ascends; E, the grate bars formed of welded wrought-iron tubes, and
connect F and G, an ordinary saddle boiler seen in cross section at
Figure 3, and shown in Figure 3 in side elevation by dotted lines;
H, return flues; K, ash-pit; L, brickwork.
Having now fully described and ascertained the nature of this my
said Invention and the best means I am acquainted with for carrying
out the same practically, I wish it to be understood that I do not limit
myself to the precise detail, dimensions, or proportions, as it will be
readily seen that the same may be considerably varied without departing
from the Invention.
I also desire it to be understood that I make no claim to the use of
saddle boilers alone, but what I claim is, the construction and use of
the apparatus hercin-before fully described and set forth, the improved

page_text: water heating apparatus constructed and operated substantially in the
manner and for the purposes herein-before fully described and set forth,
either alone or in combination with saddle and other boilers.
In witness whereof, I, the said Frederick John Mee, have here-
unto set my hand and affixed my seal, this Fourth day of July
in the year of our Lord One thousand eight hundred and seventy-
one.
