Improvements in Lamp Stoves.
I, CHARLES STANFORD UPTON, of 42 Park Place, in the City of New York,
State of New York, U.S.A. Manufacturer, 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 invention relates to lamp-stoves, and particularly to that class of combined
lamps and stoves, which may be used either for heating or illuminating purposes
as desired, being provided with a heating attachment, which may be substituted for
the ordinary transparent glass-chimney, used when illumination is desired.
The object of my invention is to provide a heating attachment for lamp-stoves of
the class above described, which while being light and simple, and cheap of
construction, shall yet be strong and capable of sustaining considerable weight
upon its spider or grid, without injury to either the heating attachment itself, or to
the lamp.
This object is attained in the invention herein described and illustrated in
the drawing, which accompanies and forms part of this application, in which
the same reference numerals indicate the same or corresponding parts, and in
which:
Figure 1, is an elevation of the lamp-stove, showing the heating attachment
applied thereto.
Figure 2, is a similar view in which the heating attachment has been removed,
and a glass chimney substituted therefor, the stove being then adapted for
illuminating purposes.
In the drawing, 1 is the base or oil-tank of the stove supplied with the usual
filling orifice, and with the burner 2, and wick-adjusting device 3, the burner being
of the central draft class, such as is used on the well known "Rochester Lamp." I
do not, however, limit myself to the use of this particular burner, nor to this
particular class of burners, though they are especially well adapted to the purpose
on account of the large amount of heat given out. The burner is supplied with the
usual chimney supporting collar 4, having the springs 5, for holding the chimney in
place.
The heating attachment, shown in Figure 1, consists of a chimney 6, which is
preferably of metal, and may be supplied with a hinged door filled with trans-
parent material, which thus gives ready access to the lamp for lighting and
extinguishing the same, and likewise permits some light to escape into the room.
To the lower end of this chimney is secured a collar 8, of a size adapted to rest
upon the chimney supporting collar 4, and to be held in place by the springs 5,
as shown.
Upon the top of the chimney 6, is placed the spider or grid 7, which is of the
usual construction. Secured to this grid 7, are vertical rods or pillars 10, the ends
of which rest upon the base 1, of the lamp, passing through the apertures in
These rods or
braces 9, secured to and projecting radially from the collar 8.
pillars 10, are intended to carry the weight of the heating device, with whatever
article may be resting on the grid, the chimney supporting device of the burner
merely serving to hold the heating device in position. Since the rods or pillars 10
must necessarily be of considerable length, and might bend or buckle were the load
applied at the top alone, I have made the chimney 6, with the collar 8, and
projecting braces 9, of considerable strength, and the ends of these braces rest upon
shoulders 11, formed upon the ends of the rods or pillars 10, the weight or a large
portion thereof, being thus transferred from the grid, through the chimney 6,
collar 8, and braces 9, to the rods 10, near the lower ends thereof, thus preventing

page_text: any buckling of these rods. The shoulders 11, may be in one piece with the rod 10,
but are most cheaply and easily formed, by slipping tubular sleeves of the proper
size over the rods 10, while assembling the heating device.
While I have shown the rods 10, as straight, it is not essential that they should
be so, and in order to make the heating device more compact, it may be advisable
to carry these rods 10, inward at a point just above the braces 9, so that they will
lie very close to the chimney 6. This can, however, be done without departing from
the scope of my invention.
In using the lamp-stove, it will be seen that in order to adapt it for heating
purposes, all that is required is to remove the glass chimney used for illuminating
purposes, and to substitute therefor the heating device above described, the collar 8,
fitting into the chimney supporting device of the burner, in the same manner that
the glass chimney just removed formerly fitted.
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 lamp having an ordinary burner 2, and chimney
support 4, of a heating attachment consisting of a chimney 6, having a collar 8, at
the lower end thereof, adapted to enter the said chimney support and to be held in
place by the springs 5, a grid 7, at the top of said chimney, rods or pillars 10,
attached to said grid and resting upon the body of the lamp, and braces 9 for said
rods or pillars, attached to and projecting radially from said collar 8, substantially as
described.
2. The combination, with a lamp having an ordinary burner 2 and chimney
support 4, of a heating attachment consisting of a chimney 6, having a collar 8 at
its lower end adapted to enter the said chimney support and to be held in place
by the springs 5, thereof, a spider or grid 7 at the top of said chimney, rods or
pillars 10 attached to said spider and resting upon the body of the lamp, and
braces 9 attached to and projecting radially from said collar, and resting upon
shoulders 11, of said rods, substantially as described.
3. The combination, with a lamp having an ordinary burner provided with a
suitable chimney support, of a chimney adapted to fit such support and provided at
its upper end with a heating spider or grid, radial braces 9, attached to the lower
portion of the chimney, and rods or pillars 10, passing through the ends of the
braces 9, and supporting the spider or grid by resting upon the top of the lamp body,
substantially as described.
4. The combination, with a lamp having an ordinary burner provided with a
suitable chimney support, of a chimney adapted to fit such support, radial braces 9
attached to the lower portion of the chimney, rods or pillars 10 supported by the
top of the lamp body passing through and supporting the braces, and a heating
spider or grid supported at the top of the chimney by the said rods, substantially as
described.
