PROVISIONAL SPECIFICATION.
Improvements in Kitchen or Cooking Ranges.
I, JAMES ATKINS, of Hampton House Malvern, in the County of Worcester
Gentleman do hereby declare the nature of this invention to be as follows:-
In kitchen or cooking ranges as ordinarily constructed great waste of heat
occurs from radiation and convection and great inconvenience is occasioned to the
cook and occupants of the room in which the range is situated by the escaping
heat.
The object of my invention is to prevent the waste of heat referred to and to
secure to the persons engaged in the room containing the kitchen range exemption
from the oppressive heat to which they are commonly exposed.
My said invention consists in the adaptation to the fronts of kitchen or cooking
ranges in the manner hereinafter described of a series of transparent horizontally.
sliding doors by which the heat is retained. Owing to the transparency of the
said doors the enclosed vessels or articles can be readily inspected.
I employ preferably three pairs of the said sliding doors one pair extending
from the top of the range to the level of the plate rack a second pair extending
from the level of the plate rack to the level of the hot plate and the third pair
extending from the level of the hot plate to near the level of the bottom of the
ovens and grate. The said sliding doors consist of light framings preferably of
iron having small panes of thin glass. The junction of each pair of doors is at or
near the middle of the range and they are so arranged that one of the doors of each
pair can slide behind the other door of the same pair. When the upper and
middle pairs of doors are closed the heated air above the hot plate is enclosed and
utilised and prevented from escaping into the room while the closing of the bottom
pair of doors prevents or greatly diminishes the radiation from the ovens and fire.
The sliding doors can be opened and closed so readily that their use adds but little
to the labour of the cook or attendant while the protection from heat which the
said doors afford adds greatly to their comfort and the risk of setting fire to the
dress is obviated.

Improvements in Kitchen or Cooking Ranges.
I JAMES ATKINS, of Hampton House, Malvern, in the County of Worcester
Gentleman, do hereby declare the nature of my invention and in what manner the
same is to be performed to be particularly described and ascertained in and by the
following statement :-
In kitchen or cooking ranges as ordinarily constructed great waste of heat
occurs from radiation and convection and great inconvenience is occasioned to the
cook and occupants of the room in which the range is situated by the escaping
heat.
The object of my invention is to prevent the waste of heat referred to and to
secure to the persons engaged in the room containing the kitchen range exemption
from the oppressive heat to which they are commonly exposed.
My said invention consists in the adaptation to the fronts of kitchen or cooking
ranges in the manner hereinafter described of a series of transparent horizontally

page_text: sliding doors or sliding doors covered with wire gauze by which the heat is retained.
Owing to the transparency of the said doors the enclosed vessels or articles can be
readily inspected.
employ preferably three pairs of sliding doors one pair extending from the top
of the range to the level of the plate rack; a second pair extending from the level
of the plate rack to the level of the hot plate, and the third pair extending from
the level of the hot plate to near the level of the bottom of the ovens and grate.
The said sliding doors consist of light framings preferably of iron having panes of
thin glass. In order however to avoid the breaking of sliding glass doors trans-
parent sliding doors of wire gauze or sliding doors of sheet iron or other material
may be used. The junction of each pair of doors is at or near the middle of the
range and they are so arranged that one of the doors of each pair can slide behind
the other door of the same pair. When the upper and middle pairs of doors are
closed the heated air above the hot plate is enclosed and utilized and prevented
from escaping into the room while the closing of the bottom pair of doors prevents
or greatly diminishes the radiation from the ovens and fire.
Instead of using pairs of sliding doors at each division of the range as described,
some of the divisions may be furnished with three sliding doors.
Figure 1 of the accompanying drawing represents in front elevation a kitchen or
cooking range provided with my improvements;
Figure 2 represents a horizontal section of the same taken on the dotted
line a, a Figure 1, through the sliding doors at the plate rack;
Figure 3 represents a horizontal section of the same taken on the dotted line b, b
Figure 1, through the sliding doors situated between the plate rack and the hot
plate and
Figure 4 represents a horizontal section of the same taken on the dotted line c, c
Figure 1 through the sliding doors situated in front of the ovens and grate ;
Figure 5 represents a front elevation of one of the last named sliding doors.
In the drawing one of the sliding doors of each pair or set is represented partly
opened.
The same letters of reference indicate the same parts in the several figures of
the drawing.
d; e e are the pair of sliding doors extending in front of the space between the top
of the range and the plate rack. These sliding doors d, e consist of frames of
metal glazed with panes of thin glass. The said doors slide in parallel grooves or
channels, in the metal cross bars g, g at the front of the range, the door e sliding
in frout of the door d and the door d sliding behind the door e. Owing to the
transparency of the sliding doors d, e the enclosed vessels or articles can be readily
inspected.
h,i,k are the sliding doors extending from the level of the hot plate to the plate
rack. These doors consist of metal frames covered with fine wire gauze. The
said doors h, i, k slide in the parallel grooves f¹, f¹ in the cross bars g, in front of
the range, the doors h, k sliding in the back groove and the other door i in the
other groove and in front of the doors h, k.
The sliding doors in front of the ovens and fire grate are marked m, n, p and are
somewhat similar to the wire gauze doors h, i, k and slide in parallel grooves f,
in the cross bars and q at the front of the range. The articles on the plate rack
and hot plate may be inspected through the transparent wire gauze doors.
In place of the wire gauze sliding doors h, i, k and n, p, q sheet iron or other
doors not injuriously affected by heat may be used and to prevent the passage of
hot air through the meshes or perforations of the wire gauze doors, each wire gauze
sliding door may be provided with a hinged or sliding door of sheet iron or other
material by opening which last mentioned doors the vessels or articles on the plate
rack or hot plate can be inspected through the wire gauze doors.
The several doors are opened and closed by the knobs or handles at their ends.
When the upper and middle doors d, e and h, i, k are closed the heated air above
the hot plate is enclosed and prevented from escaping into the room, while the

page_text: closing of the bottom doors m, n, p prevents or greatly diminishes the radiation of
heat from the ovens and fire place.
The sliding doors can be opened and closed so readily that their use adds but
little to the labour of the cook or attendant, while the protection from heat which
the said doors afford adds greatly to their comfort and the risk of setting fire to
the dress is obviated. As each set of sliding doors is independent of the other
sets, each set can be opened and closed and their position adjusted without
interfering with the other sets of sliding doors.
Instead of using three sliding doors between the rack plate and hot plate and
three sliding doors opposite the ovens and fire grate as described and represented,
a pair of sliding doors or more than three sliding doors may be employed; and the
frames of the last named doors may be glazed with panes of thin glass instead of
being covered with wire gauze.
Having now particularly described and ascertained the nature of my inven-
tion and the manner in which the same is to be performed I declare that I claim
as my invention;
The adaptation to or combination with the fronts of kitchen or cooking ranges
of a series of transparent horizontally sliding doors or horizontally sliding doors of
wire gauze or of sheet iron or other metal or material alone or in conjunction with
wire gauze, the said doors being arranged and used for the purposes and
substantially as hereinbefore described and illustrated in the accompanying
drawing.
