Improvements in or connected with Lamp Stoves.
I, CHARLES MELBOURNE WHITE of the Firm of White and Woodington of
27 Southampton Buildings in the County of London Patent Agent, do hereby
declare the nature of this invention a communication to me by Jacob Hirschhorn
of Berlin in the Empire of Germany Lamp Manufacturer to be as follows:
1
The invention relates to that class of lamp stove which is formed with a tall
cylindrical or rectangular body and intended more especially for use in halls and
other situations for the purpose of warming buildings, and the object of the present
invention is to give to such stoves an improved appearance and to render the same
more efficient in use than heretofore.
In stoves of this character a round wick central draught burner is generally
employed, and the burner casing has formed or fixed therewith at the upper part
thereof au apertured plate disc or rest of large diameter upon which the body of
the store which constitutes the chimney removeably seats.
This arrangement is objectionable in many respects, one being that the parts are
loose and another that the body of the stove becomes highly heated and con-
sequently in course of time becomes discoloured thus detracting from the ornamental
appearance of the stove.
Now according to the present invention in lieu of making the chimney answer
the purpose of the body of the stove as heretofore, the body of the stove is formed
of a separate tubular pedestal or casing of round or other suitable section, and at
the front of this body or casing is formed an opening to allow of the insertion and
removal of the lamp, whilst within this body or casing is arranged an inner body or
chimney of slightly less diameter than the outer casing or body of the stove.
The apertured plate disc or rest in lieu of being fixed with the casing of the
burner as heretofore is fixed to the lower end of the inner body or chimney and
the casing of the burner is formed with a gallery or seat of small diameter upon
which the apertured plate or disc rests the meeting faces of those parts being
curved or otherwise shaped to form the necessary close fit the weight of the inner
body or chimney being all that is necessary to maintain a tight joint between the
parts.
.
By this arrangement in addition to the volume of air which passes up through
the burner and chimney or inner body, and thereby becomes heated a draught is
created between the outer body or casing and the inner body or chimney thus
causing a large volume of air to be circulated and heated, and thereby rendering
the store more efficient than heretofore, added to which the outer body or casing
of the stove is protected by the wall of air between it and the inner body or
chimney, and consequently is not liable to discolouration by over-heating.
Furthermore the outer casing or body forms a protection against the accidental
contact of articles of dress or the like with the heated chimney, and which might
result in a serious accident.
In order to raise the inner body or chimney off the burner, in order to light or
trim the same, the inner body or chimney is provided with lateral projections or
studs which pass through vertical slots formed in the outer body and terminate in
knobs or handles, by the aid of which the inner body or chimney may be lifted to
the required height whilst in order to retain it in that position the -vertical slots
terminate in horizontal inclined offsets or recesses adapted to engage the studs, so

page_text: that by raising the inner body or chimney to the required height and giving a
slight rotation thereto by the aid of the handles it will be held suspended in that
position until it is again lowered to seat upon the burner.
The inner body or chimney may be guided in any suitable manner so that when
it is lowered into position it will accurately register with the burner of the lamp.
It will be evident that in lieu of the arrangement of catches hereinbefore
described, any other suitable devices may be employed for holding the inner body
or chimney in its raised position.
The inner body or chimney the lower part of which is exposed to view for part
of its circumference is provided with a talc window in order that the light from the
lamp may be admitted to the room, but in order to give a more cheerful
appearance to the stove, according to the present invention the talc window is
surrounded by a projecting frame in which is removeably mounted a sheet of ruby
glass, by which means the glass is protected from the injurious action of the
extreme heat and the appearance of the stove when in use is much improved.
In lamps of this character it is usual to fix the burner casing with the lamp by
means of bayonet catches or the like, but such devices do not possess the solidity
which is necessary in a burner which is required to support a chimney or body of
the character herein referred to.
Now according to another part of the present invention, the burner casing is
formed with laterally projecting brackets which are longitudinally slotted to
engage corresponding turn buttons mounted upon the reservoir or container of the
lamp, so that by passing the turn buttons through the slots and then turning them
at right angles thereto, the burner casing may be securely and solidly fixed with
the other part of the lamp without risk of its becoming accidentally detached
therefrom.
By the means herein before described at a small additional cost, the stove is
rendered much more serviceable and ornamental than heretofore.

DESCRIPTION OF THE DRAWINGS.
Figure 1 is a front elevation of a lamp stove constructed according to the present
invention.
.
Figure 2 is a side elevation thereof.
Figure 3 is a horizontal section taken on the line 1-1 of Figure 1.
Figure 4 is a vertical transverse section taken on the line 2-2 of Figure 3.
: Figure 5 is a detail view of parts showing the inner body or chimney about to
seat upon the burner casing.
Figure 6 is a front elevation of part of the stove drawn to an enlarged scale and
representing more particularly the means of fixing the, burner casing with the
lamp.
Figure 7 is a side elevation thereof and
Figure 8 is a plan thereof.
:
Figure 9 is a vertical transverse section partly in elevation of a stove representing
a slight modification and
Figure 10 is a horizontal section taken on the line 3-3 of Figure 9.
In the several figures like parts are indicated by similar letters of reference.
Referring to Figures 1 to 8 a represents the body of the stove which is of
cylindrical, although it might be of rectangular, shape and formed of sheet iron and
à represents the base of the stove which is formed of cast iron and of the shape of
á ring and is furnished with feet a¹ upon which the stove rests and with flanges a¹**
which support the lamp in position.
The body a at the top thereof is furnished with a nest a³ of rings adapted to
close or more or less open the upper part of the body a according to whether at
the moment it is intended to employ the stove solely for heating purposes or to boil
a kettle or the like (as represented at Figure 9) and a represents an ornamental
removeable lid or cover to the body a.
.
b represents the lamp or container which is furnished with a central draught
burner as is customary in stoves of this character and 6' represents the burner
casing.
The body a of the stove is formed of a tubular pedestal or casing of round or
other suitable section and at the front of the body or casing a is formed an
opening a to allow of the ready insertion and removal of the lamp b.
Within the body or casing a is arranged an annular and vertically moveable
body or chimney c of slightly less diameter than the outer casing or body a of the
stove and the apertured plate disc or rest c' instead of being fixed with the casing 6¹
of the burner as heretofore is according to the present invention fixed to the lower
end of the inner body or chimney_c.
The casing 6' of the burner is formed with. a gallery or seat 61* of small diameter
apon which the apertured plate or disc c¹ of the inner body or chimney crests, the
meeting faces of those parts, that is to say the gallery or seat 61* and the apertured
plate being curved or they might be otherwise shaped to form the necessary
close fit, the weight of the inner body or chimney c being all that is necessary to
maintain a tight joint between the parts.
By this arrangement, in addition to the volume of air which passes up through
the burner and chimney or inner body c and thereby becomes- heated, a draught is
created between the outer body or casing a and the inner body or chimney c thus
causing a large volume of air to be circulated and heated and thereby rendering
the stove more efficient than heretofore added to which the outer body or casing a
of the stove is protected by the wall of air between it and the inner body or
Chimney c and consequently is not liable to discolouration by overheating.
Furthermore the outer casing or body a remains comparatively cool, and there
is consequently no risk of fire from the contact therewith of articles of dress, and

page_text: inasmuch as the highly heated chimney or inner body c is enclosed within the outer
body a it is impossible for articles of dress or the like to come into contact with its
heated surface, and which in a stove of ordinary construction might result in a
serious accident.
In order to raise the inner body or chimney c off the burner of the lamp 6 in
order to light or trim the same the inner body or chimney c is provided with lateral
projections or studs which pass through vertical slots a formed in the outer
body a and terminate in knobs or bandles 2 by the aid of which the inner body
or chimney c may be elevated to the required height whilst in order to retain it in
its raised position the vertical slots a arranged upon opposite sides of the body a
and terminate in horizontal inclined or curved offsets a*, which take the saine
direction having regard to the circumference of the body a and are adapted to
engage the studs so that by raising the inner body or chimney c to the required
height and giving a slight rotation thereto by the aid of the handles it will be
held suspended in that position as represented by the dotted lines in Figure 4 until
it is again lowered to seat upon the burner.
It will be evident that in lieu of the arrangement of catches lastly hereinbefore
described, any other suitable devices may be employed for holding the inner body
or chimney c in its raised position.
The inner body or chimney c may be guided in any suitable manner so that when
it is lowered into position it will accurately register with the burner of the lamp
and in the present example the inner body c is provided with ribs or projections c*
for that purpose.
The inner body or chimney e, the lower part of which is exposed to view for
part of its circumference as shown more particularly at Figures 1 and 2, is provided
with a tale window c in order that the light from the lamp 6 may be admitted to
the room or apartment in which the stove is placed, but in order to give a more
cheerful appearance to the stove, according to the present invention the tale
window is surrounded by a projecting frame c* in which is removeably mounted
a sheet of ruby glass by which means the glass c is protected by the tale c from
the injurious action of the extreme heat emanating from the flame of the lamp and
the appearance of the stove when in use is much improved.
In lamps of this character it is usual to fix the burner casing 6' with the lamp b
by means of bayonet catches or the like, but such devices do not possess the solidity
which is necessary in a burner which is required to support a chimney or body of
the character herein referred to.
Now according to another part of the present invention the burner casing b¹ has
fixed therewith laterally projecting brackets 63 which are formed with longitudinal
slots 6* which engage corresponding turn buttons 6 mounted with capability of
turning upon standards or brackets 68* fixed with the top of the reservoir or
container 6 of the lamp, so that by passing the turn buttons 68 through the slots 6**
and then turning them at right angles thereto as shown more particularly at
Figures 6 to 8, the burner casing may be securely, and solidly yet removeably
fixed with the other part 6 of the lamp without risk of its becoming accidentally
detached therefrom.
In the example given at Figures 9 and 10, the inner body or chimney c has
fixed therewith and with the studs c³ a guide c* of cylindrical form the office of
which is to guide the inner body or chimney c in its movements as hereinbefore
described with respect to the previous arrangement so that when it is lowered into
position, it will more less accurately register with the gallery or seat 61* of the
burner 6 and the cylindrical guide c* also serves the purpose of further insulating
the body a from the heat of the lamp.
It will however be evident that in lieu of the guides * hereinbefore shown and
described any other suitable arrangement of parts might be employed to guide the
inner body or chimney c in its movements.
In this example the frame for supporting the ruby glass is dispensed with but
advantage is taken of the cylindrical guide c* to carry the ruby glass at the

page_text: required distance from the talc window and for this purpose guides c¹ are fixed
with the cylinder c* and carry a sliding shutter c** which has removeably. fixed
therewith a sheet of ruby glass c³.
The shutter is pierced with ornamental perforations to allow of the passage
therethrough of rays of light from the lamp whilst it is also provided with a
handle by the aid of which it may when desired be raised to give a view
through the talc window c³ of the flame of the lamp.
Although the outer body a of the stove and the inner body or chimney care
described as cylindrical in form, it will be evident that they may be of rectangular
or other suitable shape provided the devices e a* for holding the inner body or
chimney c suspended are modified so as to avoid the turning of the inner body c for
that purpose and it will be obvious that many simple devices may be employed for
that purpose and such as hooks carried by the handle * engaging eyes or the like
carried by the body a in place of the offsets a* of the slots a³.
By the means hereinbefore described at a small additional cost the stove is
rendered much more serviceable and ornamental than heretofore.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In a lamp stove the combination of a fixed outer body a vertically moveable
inner body or chimney a seat or gallery carried by the lamp and a corresponding
part carried by the lower end of the inner body or chimney the diameter of the
inner body with relation to the outer body being such as to leave an air passage
between those parts substantially as herein shown and described and for the
purposes stated.
2. In a lamp stove the combination of a fixed outer body, a vertically moveable
inner body or chimney, a seat or gallery carried by the lamp, a corresponding part
carried by the lower end of the body or chimney and means for guiding the inner
body or chimney in its movements substantially as herein shown and described and
for the purpose stated.
3. In a lamp stove the combination of a fixed outer body a vertically moveable
inner body or chimney a talc window in the inner body or chimney a projecting
frame surrounding such window and a sheet of coloured glass, mounted in such
frame substantially as herein shown and described.
4. In a lamp stove the combination of slotted brackets fixed with the burner
casing and corresponding turn buttons rotatively fixed with the lamp, reservoir or
container as a means of solidly but removeably fixing the burner casing with the
lamp reservoir substantially as herein shown and described.
