PROVISIONAL SPECIFICATION.
Improvements in Chimneys for Oil Stoves.
We, ELIZA RIPPINGILLE, Lamp and Stove Manufacturer, and WILLIAM
PORTER, Foreman, both of The Aston Brook Lamp Works, Birmingham, in the
County of Warwick, do hereby declare the nature of this invention to be as
follows:-
The invention has for its object a novel construction of chimney for oil stoves
having large flat wicks, and relates more particularly to that class of lamp which
is used within a stove body for warming purposes and which at the same time
permits of the passage of light from the flame to the exterior of the stove.
A chimney entirely of glass would be both difficult and expensive to make and
would be very soon destroyed by the intense heat to which it would be subjected,
whilst a chimney entirely of metal would not allow the passage of light.
According to our invention we make the main body of the chimney of metal and
we form the lower part on each side of a metal frame filled in with glass, the glass
for the larger-sides, and if desired the smaller, being in two or more strips to allow
of varying expansion and contraction of the parts thereof, and in order to
facilitate the renewal of such glass without the need for a mechanic, we make one
side of each side frame hinged or otherwise movable and we fix it in position
by turnbuttons or other suitable fastenings, said movable sides being so formed
as to make a sufficiently airtight joint at such part. The body of the chimney
is formed of sheet metal rivetted at the joints and the upper part is made narrower
in cross section than the lower part containing the glass sides, a short incline or
curve connecting the broader and narrower parts.

Improvements in Chimneys for Oil Stoves.
We, ELIZA THORPE, formerly Eliza Rippingille, Lamp and Stove Manu-
facturer, and WILLIAM PORTER, Foreman, both of The Aston Brook Lamp
Works. Birmingham, in the County of Warwick, 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 :-
The invention has for its object a novel construction of chimney for oil stoves
having large flat wicks, and relates more particularly to that class of lamp. which
is used within a stove: body for warming purposes, and which at the same time
permits of the passage of light from the flame to the exterior of the stove.

page_text: A chimney entirely of glass would be both difficult and expensive to make and
would be very soon destroyed by the intense heat to which it would be subjected,
whilst a chimney entirely of metal would not allow the passage of light.
According to our invention we make the body of the chimney of metal and we
form the lower part on each side of a metal frame filled in with glass, the glass for
the larger sides, and, if desired, for the smaller, being in two or more strips to
allow of varying expansion and contraction of the parts thereof, and in order to
facilitate the renewal of such glass without the need for a mechanic, we make one
side of each side frame hinged or otherwise movable, and we fix it in position by
turnbuttons or other suitable fastenings, said movable sides being so formed as to
make a sufficiently air-tiglit joint at such part. The body of the chimney is
formed, of sheet metal rivetted at the joints, and, the upper part, is made, narrower
in cross section, than, the lower part containing the glass sides, a short incline or
curve connecting the broader and narrower parts.
And in order that the invention may be more clearly understood and readily
carried into effect, we will proceed, aided by the accompanying drawings, more
fully to describe the same.
Figs. 1 and 2 are two side elevations, drawn at right angles to each other, and
Figs 3 is a vertical cross section, of an oil stove chimney constructed according to
our invention, and Fig. 4. is a horizontal section of one: corner of the metal frame
separately..
The: lower part of the chimney is constructed along the vertical angles; of metal
frames a a formed with grooves at a', see Fig. 4, and such frames aa are connected
together at the bottom by a rectangular frame 6 rivetted thereto and formed' with
ledges or grooves 61 to support the glass sides, which consist of strips of glass cc
passed into the grooves.a a at the upper end of the latter. The upper ends of the
frames aa are rivetted to the upper part d of the chimney, which latter is made
narrower in one direction than the lower part thereof, short inclined or curved
parts ee connecting the wider sides of the broader and narrower parts together:
The upper part d of the chimney may be made entirely of metal, but, if desired,
the wider sides may be formed mainly of sheets of mica d¹ to enable light to pass
therethrough.
.
In order to facilitate the renewal of the glass sides c c without the need for a
mechanic, we make the upper sides of each side frame hinged at ff, or
otherwise movable, and we fix them in position by turnbuttons, the tongues 3
of which pass through key-hole openings d2 in the upper part d of the chimney.
The lower edges of the parts are bent at right angles to the main parts thereof in
order to securely, hold the glass in, position, and said parts are also, by such.
turnbuttons, held securely against the fixed metal parts of the chimney, so as to
cover the openings d2 and make sufficiently air-tight joints at such parts.
It is evident that parts may be otherwise formed, mounted and secured in
position, or such parts may be dispensed with; it is however advisable to use them
as they enable the chimney to be handled and transported safely.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed,, we declare that what
we claim is :-
1. The peculiar construction of chimney for oil stoves substantially as herein
shown and described and for the purpose stated.
2. The improved chimney for oil stoves the lower part of which consists of a
metal frame filled in with strips of glass which are readily removable,, substantially
as herein shown and described.
3. The improved chimney for oil stoves the lower part of which consists of a
metal frame having fixed sides and' bottom filled in with strips of glass and a
movable upper part of such frame to enable the glass to be inserted and renewed
substantially as herein shown and described:

page_text: 4. The improved chimney for oil stoves the lower part of which consists of a
metal frame filled in with strips of glass which are readily renewable and having
an upper narrower part connected with the lower broader part by short inclines or
curves, substantially as herein shown and described.
