Ventilator Manufacturers do hereby declare the nature of this invention to be as
follows:-
And consists in making the stove in the form of a Bridge, arch, or saddle, or the
letter U upside down, the oil or gas may be supplied at one or both of the leggs of
the aformentioned, bridge, arch, saddle or the letter U, aformentioned, the space
between the leggs, aformentioned may be used for an oven, or if preferred the oil or
gas may be removed, to the aformentioned space between the aformentioned leggs,
and consumed theren, by making the internal part duplicate. The vapours inside of
stove caused by heating are taken away from the stove by an arrangement at the
highest part of stove, as well as at the extreem lowest part, and are condensed, this
stove may be used without a flue, where necessary there will be a number of tubes,
running horizontal when necessary to provide greater heating surface, the arrange-
ment for condenceing. The vapour will consist of a pipe or passage from the extreme
height of the stove extending to the lower part of stove the hot air in the aforesaid
pipe will be forced down to the lower end of pipe and condensed there will be a
constant circulation of hot air in the same manner, this does not take place until the
heated air has circulated over a great part of the inner surface of the stove.
Dated this 23rd day of December 1886.

page_text: WILLIAM LORD and JAMES CLARK Ventilator Manufacturers 14 Marsh Road
Middlesbrough on Tees Yorkshire do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
In carrying our invention into effect we provide one, two or more cylinders of iron
or any material preferable. Where two cylinders are employed they will be joined
together in the form of a bridge at the top; the space between the cylinders may be
used as an hot air chamber for any purpose suitable; at the front side of these
cylinders, a recess will be provided for the purpose of fixing the gas burner, or for the
reception of an oil vessel, this recess will be provided with a reflector; the back of the
recess may be flat but a round back will be preferred, an argand burner or a bunsen
burner or an ordinary burner may be employed. Behind the recesses we provide an
iron plate extending from an inner top about an inch from the outside top. This
plate extends to each side of the cylinders. The space between the two tops is provided
for the heated air to circulate in; the hot air is then forced down the two side passages
or flues formed by the plate being fixed on to the back of the recesses; this plate
extends about half way down the cylinder and is left open at the end. We provide
another plate fixed about two or more inches from the aforesaid plate forming a second
passage or flue for the hot air. This plate does not reach the top of the stove within
one or more inches; but it depends 'lower than the first plate. Those plates or
divisions may be multiplied where greater condensing powers are required. The last
plate or division must not reach the inside top closer than one inch, about two inches
is preferable; it will however depend to a lower part of stove or cylinder. We
provide an outlet from the last chamber opposite the space not covered by the last
plate this outlet is connected to a condensing pipe depending to almost the same
distance as the last plate inside the cylinder entering into the cylinder at this part or
position. The space between the last plate and the cylinder in connection with the
outside tube is used as a condenser; in this space and pipe there is a constant
circulation of hot air taking place. The inside of the base will be made in a dished
shape with an outlet in the centre to allow the condensed vapours to drop into a small
receptacle provided for it under the stove. The base of the stove will be mounted on
supports to allow anything to be placed under the outlet where the condensed vapours
drop out. At the top of the recesses in front of the cylinders we provide
an inlet in
which the chimney of an argand or other burner may be inserted. Where a glass
chimney is used the chimney will be provided with a short taper ferrule. This taper
ferrule slips into the inlet provided for the chimney, the wide end of taper piece or
ferrule will be turned inwards forming a ledge the chimney being free to move up
and down the ferrule. When the ferrule is on the chimney. In lighting the burner
the chimney can be lifted on to the ledge. When you desire to take out the chimney
to clean it draw the ferrule down and the chimney and the ferrule will come out
together. Providing gas jets or burners are employed without a chimney we provide
larger inlet at the top of the recess in front of stove, the front or face of the recess
may be covered with mica made air tight around the edges; plate glass may be used
if annealed or it may be ribbed; the necessary arrangement being provided for the

page_text: supply of fresh air to the burners. This stove may be made with one single cylinder
only or it may be made with a series of cylinders.

centre. Figure 2 is a back elevation. Figure 3 a side section. Figure 4 a plan. Figure 5

to each figures. A, figure 1, 2, and 3 shows the outside casing or cylinder.

show the dished base with outlet for condensed vapours. E, figures 1, 3 and 5 show
the argand chimney on the burner. I, figures 3 and 4 shows the first plate behind
the recess extending down the cylinder about half way. H figures 1, 3, and 5 show
the ferrule and chimney. J figures 3 and 4 shows the second and last plate of this
size of stove, this plate being turned back at the top end at about right angles as on
the drawing to offer a resistance to the passage of hot air into this chamber; instead
of allowing the hot air to pass down freely we obstruct its passage and allow the hot
air to go freely down the condensing pipe L figure 3. K figure 4 shows the side
passages or flues. L figures 1, 2, 3, 4 and 5 show the outside condenser or circulating
pipe. LL figure 3. shows the circulating or condensing chamber. M figure 4 shows
the cradle form recess. X figure 1 and 2 shows the hot air chamber. The action of the
stove is as follows the gas being lit the hot air is forced into the space between the
inside and the outside- tops and forced down the side passages or flues, K figure 4 ;
the hot air returning to the under side of the inside top B and passing above the
plate J figures 3 and 4 and passing down the condenser L figures 1, 2, 3, and 4 into
the chamber or condenser L L figure 3 and 4 there being a constant circulation from
the pipe L to the chamber LL. The hot air having become cool the condensed
vapours drop out at O figures 1, 2, and 3. The heated air is the motive power that
keeps the circulation in the pipe L and the chamber L L constant providing there is
less resistance to the hot air in the outside pipe than the inner chamber. The heated
air takes the outer passage making its way down the pipe into the inner chamber LL.
The vapours rising with any hot air to the top of chamber and is urged down the
outside tube again and becomes cool this circulation is constant as long as the heat is
supplied at the inlet at recess in front of stove. These stoves may be used to advantage
wherever warmth is required.
Having now particularly described and ascertained the nature of our invention
and in what manner the same is performed we declare that what we claim is :—
First A condensing stove heated by oil or gas with a cradle shaped recess, with
a passage or flue on each side of the cradle with the chambers and condensing pipe
substantially as described, the pipe being made to project any length preferable. Wo
do not bind ourselves to retain the pipe outside of back of the stove but where
prefered an extra chamber may be formed in the stove to take the place of the pipe
where the extra diameter necessary is not an objection.
:-
Second We claim to make this stove in single cylinder or in double form with
a hot air chamber between the cylinders or it may be made in series where a great
amount of heating surface is required.
Third We claim to close the front of the stove with annealed glass, mica, or iron
all edges being made airtight with the exception of necessary air supplies.
Fourth-The method of making the chimney fit with the ferrule; and ledge on
broader part of ferrule; this ferrule is used to keep the vapours back and for holding
the chimney when lighting burner.
