Year: 1873

page_text: LETTERS PATENT to William Verity and Benjamin Verity, both of
127, Regent Street, in the County of Middlesex, for the Invention
of "IMPROVEMENTS IN HEATERS OR BOILERS FOR HEATING CONSERVATORIES,
HALLS, BATHS, AND FOR SUPPLYING HOT WATER FOR DOMESTIC AND OTHER
PURPOSES."
Sealed the 6th February 1874, and dated the 12th December 1873.
PROVISIONAL SPECIFICATION left by the said William Verity and
Benjamin Verity at the Office of the Commissioners of Patents, with
their Petition, on the 12th December 1873.
We, WILLIAM VERITY and BENJAMIN VERITY, both of 127, Regent
Strect, in the County of Middlesex, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN HEATERS OR BOILERS FOR HEATING
CONSERVATORIES, HALLS, BATHS, AND FOR SUPPLYING HOT WATER FOR DOMESTIC
AND OTHER PURPOSES," to be as follows:-
This Invention relates to improvements in heaters for warming
conservatories, halls, baths, and the like; also for heating water, whereby

page_text: not only a distribution of warm moist air can be ensured, but water for
domestic and other purposes can be heated at the same time.
The boiler can be of any shape and size. The lower part of the heater
is preferably constructed with an open fire-place with water tubes as
bars, the burner being of fire clay perforated at top and sides for burning &
plain gas, or air and gas combined, and concealed from view by a packing
of indestructible fuel.
Cold water is supplied by a tube at the lowest part of the boiler, and
passes round the outside of the fire-clay burner in contact with the
flames or jets by a coil arrangement, whereby the cold water supply in 1
passing through the tube becomes heated before it enters the boiler.
The open fire-place imparts a cheerful appearance, and gives out
warmth to the apartment, and radiated heat from the boiler augments
the warmth.
The waste heat from the gas fire is deflected down and impinges upon 1
the surface of the water by a baffle plate of dished form (inverted) so
that the escaping heat becomes concentrated and moistened before it
passes out of the boiler into the room or apartment. By this means the
whole of the heat is made use of before passing from the boiler.
The water is heated by the fire acting upon the inner skin of the 2
vessel and upon tubes placed horizontally or nearly so in the central
chamber, which water is available for domestic and other purposes as
required.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Verity and Benjamin Verity in the Great 2
Seal Patent Office on the 12th June 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, "WILLIAM
VERITY and BENJAMIN VERITY, both of 127, Regent Street, in the
County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her 3
Letters Patent, bearing date the Twelfth day of December, in the year
of our Lord One thousand eight hundred and seventy-three, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors, give

page_text: and grant unto us, the said William Verity and Benjamin Verity, Her
special licence that we, the said William Verity and Benjamin Verity;
our executors, administrators, and assigns, or such others as we, the said
William Verity and Benjamin Verity, 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 HEATERS OR BOILERS FOR
HEATING CONSERVATORIES, HALLS, BATHS, AND FOR SUPPLYING HOT WATER FOR
DOMESTIC AND OTHER PURPOSES," upon the condition (amongst others) that
we, the said William Verity and Benjamin Verity, or one of us, our
executors or administrators, by an instrument in writing under our, or
one of our, or their, or one of their hands and seals, should particularly
describo 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 William Verity and Benjamin
Verity, do hereby declare the nature of our said Invention, and in what
manner the same is to be performed, to be particularly described and
ascertained in and by the following statement thereof, reference being
had to the Drawings hereunto annexed, that is to say :-
This Invention relates to improvements in heaters for warming
conservatories, halls, baths, and the like; also for heating water, whereby
not only a distribution of warm moist air can be ensured, but water for
domestic and other purposes can be heated at the same time.
The boiler can be of any shape and size. The lower part of the heater
is constructed with an open fire-place, and with water tubes as bars, the
burner being of fire-clay perforated at top and sides for burning plain
gas, or gas and air combined, and concealed from view by a packing of
indestructible material.
Cold water is supplied by a tube at the lowest part of the boiler, and
passes round the outside of the fire-clay burner in contact with the
flames or jets by a coil arrangement, whereby the cold water supply in
passing through the tube becomes heated before it enters the boiler..

page_text: "
The open fire-place imparts a cheerful appearance, and gives out
warmth to the apartment, and radiated-heat from the boiler augments
the warmth.
The waste heat from the gas fire is deflected down, and impinges upon
the surface of the water by a baffle plate of dished form (inverted) so i
that the escaping heat becomes concentrated and moistened before it
passes out of the boiler into the room or apartment. By this means the
whole of the heat is made use of before passing from the boiler.
The water is heated by the fire acting upon the inner skin of the
vessel, and upon tubes placed horizontally or nearly so in the central 1
chamber, which water is available for domestic and other purposes as
required.
The Invention will be understood by reference to the annexed
Drawings, and to the following description thereof :-
Figure 1 is a sectional elevation of our heater taken through the 1
central line of the fire-bars and the back; Figure 2, a front view w;
Figure 3, a vertical section; and Figures 4 and 5, sectional plans, as
indicated.
A is the exterior and B the interior shell, the two being connected by
a hood C forming the opening of the fire-place. The sides of this hood 2
have bars D, D, forming water tubes, and in the fire-place are other
tubes E, E, as water tubes connecting one portion of the main body of
water with the other to ensure constant circulation. The fire-chamber
is occupied by a fire-clay block F, this being perforated from the sides.
and top all round it from a central chamber, in which an admixture of 2
gas from a pipe Hand air through the entry I takes place, the combined
air and gas burning from the exterior of the fire-clay block as a burner
on to asbestos or other like non-destructible body arranged on and
between the tube bars E, E, the fire-clay burner being also surrounded
by a coil of piping J, through which the supply of water to the heater a
is maintained. The cold water entering at the bottom is caused to rise
in a heated state into the main body of water to maintain its desired
temperature and its level, which is constantly changing from evapora-
tion. The smoke and products of combustion from the burner rise up
the central space K, this being traversed by flat tubes G (water) to 3
utilize all the possible heat before it escapes from the uptake K, which it

page_text: can do after striking against the baffle plate L, the edges of which are
curved downwards to deflect the heat down upon the surface of the
water, whereby it (i.e., the heat) becomes moistened, and passes into the
building or room from the outlet M. The crown or top of the heater
is closed by a plate N, and a chamber is left above, into which articles,
say, of clothing can be placed to air or to warm them as desired.
Figures 6 and 7 represent in elevation and vertical section a modified
form or arrangement of heater or boiler constructed according to our
Invention. The uptake K is of greater height with the upper part
having the deflecting or baffle plate L secured to it instead of to the
partition plate. The overflow water and the escaping heat passes
through a bent or angle tube M, this being held in position by a vertical
plate or pocket P for leading part of the overflow into the tube M in the
form of a fine shower, so that the heat which has not been deflected
down sufficiently to take up moisture from the surface of the water has
to pass through this shower, and is thus moistened before it escapes into
the apartment.
Figure 8 shows a sectional elevation of another modification. The
top chamber in this case we use as a water vessel, and we carry the
coil J up to this vessel, so that it can be kept charged, the overflow
passing off by the pipe Q into the lower part of the heater, and by which
overflow the water in the main vessel becomes heated as well as by
conduction from the sides of the uptake K, inner shell B, and the cross
tubes G. Both vessels, i.e., the main and the supplementary one at the
top, can have a separate supply by leading the coil pipe direct into the
main, and another up to the top vessel, the supply to each being
regulated by taps in any well known manner. We carry the top over-
flow pipe Q down well into the water in the main vessel to prevent the
heated air passing away by that route. The uptake in this arrangement
terminates just below the bottom of the top vessel, by which it may or
may not be deflected down upon the surface of the water. In any case
the escaping heat becomes moistened by the fine spray or shower
which falls through the apertures like from a rose as it passes through
the outlet M.
Having thus described the nature of our said Invention, and in what
manner the same is to be performed, we declare that we claim,―
The combination and arrangement of parts forming a heater as described
and shown for the purposes set forth.

page_text: Secondly. We claim the employment of a fire-clay perforated burner
surrounded by a feed water pipe (coiled) in an open fire-place arranged
in a heater, for the purposes set forth.
Thirdly. We claim the modified forms or arrangements of apparatus,
termed heaters or boilers, as described with reference to Figures 6, 7,
and 8, as and for the purposes set forth.
In witness whereof, I, the said Benjamin Verity, for myself and on
behalf of the said William Verity, have hereunto set my hand and
seal, this Twelfth day of June One thousand eight hundred and
seventy-four,
