IMPROVEMENTS IN SPIRIT LAMPS OR STOVES FOR HEATING COOKING AND OTHER LIKE PURPOSES
Year: 1885

page_text: I, THOMAS BROOKES of the Firm of Brookes and Adams of Barr Street Birmingham,
in the County of Warwick Manufacturer, do hereby declare the nature of said
invention for "IMPROVEMENTS IN SPIRIT LAMPS OR STOVES FOR HEATING COOKING
AND OTHER LIKE PURPOSES" and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement :-
Spirit lamps of the ordinary construction have only a determinate sized heating
surface, consequently they are incapable of graduating or cutting off a greater or
less amount of heat from the lamp, when less heat is required.
The object of my invention is to obtain a greater or less heating surface
according to varying requirements; this is effected by exposing a greater or less
superficial area or opening above the burner of the lamp or stove; so that a mean,
maximum or a minimum amount of heat can be obtained-This is accomplished by
having a secondary or smaller opening in the middle of the cap or cover which
encloses or encases the burner. This secondary opening has a jointed cover or lid
for covering or closing up more or less the said opening.
When a large amount of heat is required, the entire cap or covering is removed
from the lamp or stove, so as to expose a large heating surface; but when only
a minimum or small amount of heat is required, the secondary opening in the cap
is exposed only.
I will now proceed to describe with reference to the accompanying Drawing, the
manner in which the same is to be carried into effect.
Figure 1 represents a spirit lamp or stove (in plan) constructed according to my
invention, showing the secondary or smaller opening exposed; the jointed cover
being wholly removed. When in this position a mean amount of heat is attained.
Figure 2 is the same with the jointed cover overlapping the opening, so as to
present only a minimum heating surface-Figure 3 shows the cap of the lamp or
stove removed, so as to expose a large heating surface. Figure 4 is the cap
separately. Figure 5 is an elevation of figure 1 partly in section. Figure 6 is an
elevation of figure 3 partly in section, and figure 7 is a section of the cap figure 4.
Figure 8 is a modification of figure 1, the cover of the secondary opening is jointed
to move upwards or vertically instead of horizontally. Figure 9 shows the lid
thrown back, so as to expose the burner or opening.

page_text: The lamps or stoves described are applicable for heating, cooking, boiling and
other purposes.
The same letters of reference indicate the same parts in figures 1 to 7 both
inclusive of the accompanying Drawings.
a is the body of the lamp or stove, b is the cap or cover which encloses or covers
up the larger heating surface or the whole of the burner c of the lamp or stove.
d is a small lid or cover which covers the orifice or smaller opening b in the
cover b.
ee are legs or supports upon which a vessel or other object to be subjected
to the heat of the lamp or stove is placed.
In using the lamp or stove for obtaining a large amount of heat, for heating or
cooking purposes, the cap bis removed, so as to expose a large heating surface, as
represented in figures 3 and 6. When less beat is required, the cap b is placed
upon the lamp as represented in figure 1, with the opening 62 in the middle of the
said cap exposed or uncovered, as represented in figures 1 and 5; and when a still
less heat is required, the cover d is turned upon its joint d² so as to overlap the
opening b² as represented in figure 2. In the modifications figures 8 and 9, a is the
body of the lamp, b is the cap, d is the jointed cover, d² is a hinged joint; so that
in using the lamp, the cap bis removed to expose a large heating surface, and
d² is thrown back for a smaller heating surface when the cap is upon the lamp.
By using my invention, there is great economy in the consumption of spirit, as
there is no more consumed than is actually required for the heating, cooking or
other purposes to which the stove or lamp is applied.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
:-
First The improvements in spirit lamps or stoves hereinbefore described and
set forth in the several figures of the Drawing, whereby a greater or less amount
of heat can be obtained by making the closing or covering cap the means of
covering or uncovering more or less of the burner surface; the parts being arranged
and combined substantially as described and set forth.
Secondly. Making the closing or covering cap which is provided with an opening
at or about its middle and covered by a jointed lid, the means whereby a greater or
less amount of burner surface can be exposed for the purpose of obtaining a greater
or less amount of heat for heating and cooking purposes, also the jointed lids or
covers for closing the openings as set forth.
