Complete Specification Left, 9th Apr., 1891-Accepted, 9th May, 1891
PROVISIONAL SPECIFICATION.
An Improved Lamp Stove.
I, JOHN PITT BAYLY of 18 Fulham Place, Paddington, in the County of
London, Patent Agent, (a communication to me from abroad by Joseph Menge of
New Orleans, Louisiana, U.S.A. Inventor,) do hereby declare the nature of this
invention to be as follows :-
:―
This invention has for its object to provide an apparatus whereby fluids may be
readily heated and kept warm upon an ordinary lamp.
The lamp stove is preferably composed of an ordinary oil reservoir supported
upon a pedestal, and provided with a chimney which is formed with longitudinal
crimps, or flutings, which extend along its length. A cage consisting of a metal
encasement, having openings around it which are closed with mica, surrounds the
burner, and is provided with suitable feet which rest upon the oil reservoir.
Supported upon this cage is a fluid containing a receptacle, through the bottom
of which the lamp chimney projects in such a manner that the fluid contained
within the receptacle surrounds the chimney. The receptacle is provided with
a handle and spout, for the convenience of carrying it and removing its contents.
Dated this 9th day of July 1890.

COMPLETE SPECIFICATION.
An Improved Lamp Stove.
I, JOHN PITT BAYLY, of 18 Fulham Place, Paddington, in the County of
London, Patent Agent, do hereby declare the nature of this invention (a com-
munication to me from abroad by Joseph Menge, of New Orleans, Louisiana, U.S.A.
Inventor,) to be as follows:-
My invention has relation to improvements in lamp-stoves of that character or
class adapted for use in connection with a common or domestic illuminating-lamp,
by adjustment or combination of a liquid-holding vessel constructed with a central
flue to serve as the chimney of the lamp, with the wick device and body of the
lamp.
The object is to improve and simplify the existing constructions; and my inven-
tion therefore consists in the novel construction of parts and their combination, as
will be more fully hereinafter specified, and specially as the same is pointed out in
the claim made hereto.
Utensils of the character allied to my improved lamp-stove have been made with
central flues of various constructions, but lacking, so far as I am aware, in an
enlarged heating or contact surface in the flue or chimney; and it is the purpose of
my improvements to remedy this defect by making the flue or chimney crimped or
corrugated its entire length through the vessel, thus attaining enlarged heating
surfaces exposed to the action of the calorific, and of course to the liquid in the
vessel. Another purpose is to utilize that part of the flue or chimney projecting
below the bottom of the vessel as a means for giving forth the illuminating rays of
the flame, and I also construct the vessel with supports adapted to sustain it in an
upright position when removed from the lamp, and support it securely and safely
when used in connection therewith.
I have fully illustrated my invention in the accompanying drawings, forming a
part of this Specification, wherein-

page_text: Fig. 2 is a vertical central section through the vessel.
Fig. 3 is a plan of the chimney or flue, and
Fig. 4 is a perspective of the vessel.
In the drawings in the different figures where the same numerals and letters of
reference are used they designate the same parts.
Reference being had to the drawings, A designates a lamp, which may be of any
of the well known and approved kinds.
B designates the vessel to be applied to the lamp. This vessel B may be of any
desired shape exteriorly and provided with a pouring-lip 1, a handle 2, and cover.
Securely soldered in the bottom of the vessel is the chimney C. This is preferably
a tapering column having its lower part secured to the bottom, and of such length
as to have its top project above the top of the vessel. In order that the surface
heated by the calorific and in contact with the contents of the vessel may be of the
largest possible area, I form the chimney with flutings or corrugations 4, extending
for its length. They may be angular or circular in cross-section, as desired. The
lower end of the chimney projects below the bottom of the vessel and is formed
with a cage 5, having a rim-band 6, to set on the burner of the lamp. About this
cage I secure strips of mica 7, which close the windows of the cage and give the
same draughts as an ordinary lamp-chimney. At the same time. the transparent spaces
give forth the rays of the flame sufficient to light up the surroundings. The mica
may consist of a single piece, or panes to fit the windows of the case may be used.
In either case fastening-flanges 8 at top and bottom of the windows are.struck down
over the edges to hold it in position.
To the bottom of the vessel or to the rim flange of the cage are secured legs 9.
These are formed to press against the cage of the lamp, and set with their feet on
the top of the bowl of the lamp, thus holding the vessel steady in place.
When the vessel is removed from the lamp, the legs afford means for sustaining it
in an upright position on any supporting-surface. The legs are made of metal
strips or wires and may be adapted in length by bending to suit the length of the
neck of
any lamp to which the vessel may be applied.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
The lamp-stove herein described, composed of the containing-vessel B, provided
with a central chimney C, formed with longitudinal crimps or flutings 4, extended
for its length, and having a cage 5, formed with a bottom rim-flange and openings
and projecting below the bottom of the vessel, said openings being closed with mica
panes, and legs 9, secured to the vessel, substantially as described, and for the
purpose stated.
