PROVISIONAL SPECIFICATION.
Improvements in Domestic Boilers, Coppers, Pans, and the like.
I, HENRY THOMAS FENLON, of 8, Tudor Street, in the City of London, Gas
Engineer, do hereby declare the nature of this invention to be as follows:-
The object of my invention is to provide for domestic use a boiler or a copper or
a pan or the like in which the liquid shall very rapidly be heated and then be
conducted to the upper part of the apparatus above the level of the liquid or material
therein or thereabouts where it shall be discharged or ejected thereinto in one or
more jets and this arrangement is suitable for many domestic purposes such for
example as washing cooking infusing and the like.
To carry out this object I form a small cylindrical or other chamber it may be
capable of passing through the hole in the hot plate of a range and this chamber
is placed under the boiler or copper or pan or the like being connected therewith by
preferably two pipes one of which may extend nearly to the bottom of the chamber
and terminate at or about the bottom of the boiler or other utensil being very con-
veniently there covered by a perforated rose while the other extends from the
upper part of the chamber to the upper part of the boiler or other utensil above
the level of the liquid or material therein or thereabouts and preferably at the side
of the boiler or utensil where the end is closed and one or more holes are made in
the walls thereof near this end.
When therefore this apparatus is duly filled with liquid and the material to
be treated is placed therein and heat is applied especially to the small chamber
the liquid therein will very rapidly be heated and rising through the longer and
upper pipe will be discharged or ejected through the holes near the end thereof
properly performing its required function and a circulation and a constant agitation
of the liquid will be thus maintained as is desired.

Improvements in Domestic Boilers, Coppers, Pans, and the like.
I, HENRY THOMAS FENLON, of 8, Tudor Street, Blackfriars, in the City of
London, Gas Engineer, 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:-
This my invention relates to improvements in domestic boilers coppers pans and
the like and the object of my said invention is to provide or construct a receptacle
or utensil for washing cooking or other purposes in which the liquid contained by
the-said receptacle may be more rapidly heated than in similar articles at present
employed for the several purposes and in which the liquid shall be caused to
maintain a continual circulation and ebullition.
In carrying my invention into effect I form a small chamber preferably cylindrical
in shape and of a convenient size.
The said chamber is placed at a short distance beneath the body of the receptacle
or utensil to which my invention is applied and is connected therewith by means
of pipes of suitable size preferably two in number one of the said pipes extending
to within a short distance of the bottom of the before-mentioned chamber and
terminating at its upper end at or about the bottom of the larger receptacle or
vessel. The other of the said pipes extends from the upper part of the before-
Unine S1

page_text: mentioned chamber to the upper part of the larger vessel or receptacle above the
surface level of the liquid or material contained therein being carried up preferably
at the side of said vessel the upper end of said pipe being closed and a suitable
number of apertures being made in the walls thereof near the closed end.
In order that my invention may be more readily understood reference is made to
the accompanying drawing which shews in cross section a saucepan with my invention
applied thereto.
A indicates the small hollow chamber which is placed underneath the body B
of the saucepan or other vessel to which my invention is applied and is con-
nected thereto by means of the pipes C, C', the shorter of said pipes C extending
to within a short distance from the bottom of the said chamber and terminating
at its upper end at or about the bottom interior surface of the larger vessel B
where it is preferably covered with a perforated plate c. The second of the before-
mentioned pipes C₁ extends from about the top of the small chamber A and is
carried up preferably at the side of the larger vessel B to within a short distance
of the top of said vessel B the upper end being closed and a number of apertures
or perforations e being formed in the side of said pipe near the closed end
thereof.
When in use the larger vessel is filled with liquid to a level a little below
the perforations e. The said liquid will flow through the pipe C into the
chamber A and will flow into and up the pipe C₁ to the same level as that within
the vessel B.
Upon the application of heat to the lower part of the apparatus the liquid
within the chamber A will be rapidly heated and will rise in the longer pipe C¹
whence it will be discharged through the apertures e into the body of the vessel B.
At the same time the liquid will flow into the small chamber A through the pipe C
and thus a continual circulation of the liquid will be maintained as indicated by
the arrows in the figure.
My invention is especially applicable to saucepans and other utensils for use
with close ranges the smaller chamber A of the said utensil passing through the
well hole of the top plate of the range and being consequently very rapidly heated
but I do not wish to confine myself to any particular apparatus as my invention
may be applied to any utensil for boiling, cooking washing and other purposes
where it is desirable that the liquid shall be rapidly heated and a continual
ebullition agitation and circulation maintained within the apparatus throughout
the operation.
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 :-
1. The combination with a vessel or utensil for boiling cooking washing and
other purposes of a small chamber connected to the body of said vessel by
means of pipes the whole constructed arranged and operating substantially as
and for the purpose described and illustrated in the accompanying drawing.
Dated this 24th day of February 1891.
