THOMAS CRADDOOK of No. 4 Westbourne Place Aldrington West Brighton in the
County of Sussex Engineer do hereby declare the nature of this invention to be as
follows:-
By this invention the Stoves are adapted to use any kind of combustible, the con-
bustion being produced surrounded with water, which receives the heat and
diffuses it at discretion, for use to any, or all parts of the stove. The boiling point
of water being dependent upon the pressure, presents the best of regulators for
use. This agency receives the heat without loss and circulates and controls it;
whether it be used at 212 dg. or at a higher temperature the Stove being adapted
to the higher temperature by the use of tube; so coild or bent, as to form Oven,
Digester, Boiler, and Steamers. Or the same is provided in the usual way by sheet
or cast metal. Suppose the round form desired, the Oven and digester, then form
the center of the Stove and the boiling and steaming part surround it. When
the oven as such is not used it becomes a substitute for the Copper, or such liko
purpose, and when heat in the room is undesirable the nonconducting case meets
the point. But if warming and ventilating are desired the heat is at command. As
gas and Paraffine form the most cleanly and convenient combustibles this invention,
by the use of suitable burners provide for their use upon the large scale and at the
same time the Stoves present an external appearance fitting them for the drawing-
room, and the surface condenser is an addition to their utility.

page_text: THOMAS CRADDOCK of No. 4 Westbourne place Aldrington in the County of Sussex,
Engineer My present address is No. 50 Epirus Road Walham Green S.W. in the
County of Middlesex 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 :-
My provisional Specification clearly indicates the nature and object of my Invention
and the following explanation with Drawings will make all points clear.
"
In Drawing No. 1 and Figures No. 1 and No. 2"A" is the Oven and round it are
four annular divisions. B is the Flue from the Fire Box F. "C" is the first water
Vessel and "D" another water Vessel surrounding "C" and "E" indicates the
Flue continued from "B" the mode of effecting this, is by passages through "C"
and "D more clearly seen in plan Fig. 2. This "B" as shown in the plan will be
seen to connect the "B" with that in the Flue from the Fire Box " F" to that
of "E" which leads into the atmosphere. The passages through "(" and "D" in
depth are indicated by the Dotted Line in the Elevation. It will be observed that in
the top plate G are two openings, the outer one appearing to be annualer, but it
has four Metal Stays connecting this annualer part to the centre part in which
the Oven appears.
"H" indicates the Lids of "C" and "D" and the Oven "A."
The Lids covering "C" and "D" are four in number corresponding with the
Metal Stays which also form the seats for these Lids. The "C" and "D" are seen
to go through the top plate and are connected only by a pipe from "C" to "D" in
which is a four way Cock which allows the Steam from "C" to "D" to pass into "D"
or into the Atmosphere, as "D" is the steaming part of this Invention. The Cooking
pans are not shown, as they should retain the water used from the Steam Cooking.
Drawing No. 2 Figs. 1 & 2 show one of my Burner's. In this case Parafin ascends
up from the chamber "P" which also passes through the nipples "I" which are seen
to pass through "W" which is a water chamber and thence up to "J" and there it
escapes from the nipple "1" much the same as Gas, but in the Liquid state, and if it
ignites on coming in contact with the air on the nipple the object is in part accomplished,
but the chief reliance is in the saturating the surface of the Coke represented
by "K" which my experience has proved that Coke thus saturated is one of the
best modes of burning Parafin, this Coke is broken very small or it may be Coke
dust, which fills in between the nipples to the thickness of one half an inch "W,"

as in drawing No.
surrounding the
fire box "F" as seen in Fig. "1." In this drawing, it is seen that "W" is the
water channel and is connected directly through "C" from the dotted line downward's
& is a
pipe only, but above that line it is an annualer chamber "C" surrounding
the fire box, below the dotted line is "L" shewing where the air is admitted for
combustion.
"
We now come to sub-division's "M
& "N M" indicating flues and "N"
indicating annualer water chambers & if it be desired the oven would take the central
position as before by the removal of some of those parts "M. & N" Fig. No. 2 is the plan
showing the annualer chamber "C" "O" represents the pipe preceding from the
bottom of "C" to the water chamber, this water surrounds the nipples between the
Coke-dust and the top of the water chamber thereby precluding the possibility of
accident from the parafin.
We have said that the parafin ascends through the nipples and saturates the Coke
& thus we have an extensive and powerful burner. At "P" is seen the apparatus
which causes the parafin to rise to the top of the nipple by the action of "Q
pressing upon the surface of the parafin which causes it to flow to the parafin
chamber and the top of the nipples and by the rising of "Q" the reverse action takes
place & a mere balance weight is all that is required; if it be desired the same end
can be effected by a tap between "P" & the bottom of the parafin chamber from
which the nipples proceed upwards.
Drawing No. 3 Figs. "1," "2," "3" -On referring to the drawing and noting
the letters upon it, it is seen by four "W's" that it represents the water chamber in
this burner which has circular chambers with cotton wicks making a succession of
burners which on the drawing are indicated by "P" is most obviously seen in the
parafin chamber, then we have here indicated first air for combustion then water
surrounding the parafin burner which is indicated by "P" thus explaining all
relating to one burner with the exception of regulating the wick which is done by
two small mitre wheels and the wire for moving them descends down the air tube
which is available at the bottom for regulating the burner.
On looking at the drawing it will be seen dotted lines crossing the annualer air
passages in the water chamber this shows that it is necessary to have apertures through
these annualer chambers in order to effect a common communication with the water
pipe "W" and the same is requisite in the parafin chamber "P." In the parafin
chamber we have air and water pipes to provide the aperture in those annualer
channels. Above is a succession of letters indicating the Fluid passing through the
annualer passages by the initials placed on them it is seen that the water tube extends
only to the lines drawn across thein.
The plan Fig. 2 merely shows that there are only two parafin burners on either side
of the centre and that air passes through the two outside annualer chambers that being
the case the burners can be increased in number from 4 to 40 if desired by the
simple addition of diameter as seen in the drawing for each parafin burner on either
side of the centre herein is the sole use of this plan in the drawing of No. 3.
Fig. 3 simply illustrates how the water chambers are continued from the division
which determine the point at which the parafin annualer chamber opens into the
supply division "P." "P." "P." "P." which has its supply through "R" which is a
pipe "R" supplies water to the chamber below.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed I declare that what I
claim is.
Firstly "(I claim in my self contained stove or Kitchener ") the use of water for a
three fold purpose, economy in heating it for general use, next the purpose is making
it the recipient directly of the heat resulting from combustion at its highest temperature,
before radiation or conduction can impart it to any other matter or space, and
practically placing it at the disposal of mankind for any particular purpose or

page_text: at any particular spot. The annular chambers seen in the Specifications can
be made with tube sheet metal or cast metal. The tubes enable me to obtain a
larger range of temperature and the surface condenser if desired renders the whole
complete.
Secondly. I claim the paraffin burner with cotton wick-see Drawing No. 3 also
that shown in drawing No. 2 in which the air for combustion enters the combus-
tion chamber from the circumference but it may be introduced to the burners in the
same manner as in the former drawing No. 3.
