PROVISIONAL SPECIFICATION.
Improved Portable Ovens or Boxes for Heating and Drying
Purposes.
I, LOUISA HACK FORTH of Woodstock Villas, Chester Road, Erdington, in the
County of Warwick, no occupation, do hereby declare the nature of this invention
to be as follows:-
The boxes are for the purpose of heating or drying articles rapidly by the aid of
a gas jet, spirit lamp, or similar means.
I construct the box in two equal or nearly equal parts hinged together.
At the front of the box, i.e. the side furthest from the hinges, I attach a pro-
jecting handle to each of the parts, so that when the box is closed the two half
handles come together and so can be grasped in the one hand, thus serving to keep
the box shut as well as forming a handle to hold it by.
Any form of hinge may be used, but I prefer to form a hinge of 3 strips of thin
metal, each doubled together flat except just at the bend, where a loop is left to take
the wire, which is passed through the 3 loops. The centre strip is then rivetted and
soldered to the one side of the box and the outer strips to the other side. One,
two or more of such hinges may be employed to each box.
The boxes can be used plain as before described, but in case it is desired to
prevent the article to be warmed or dried from coming into contact with the outer
shell of the box, I place inside, in either or both sides of the box, wires, wire netting,
gauze, or perforated metal sheets; the wire or other device may be either fixed or
removable.
For drying purposes, the one side of the box may be perforated to allow of the
exit of the steam,

COMPLETE SPECIFICATION.
Improved Portable Ovens or Boxes for Heating and Drying
Purposes.
LOUISA HACKFORTH, of Woodstock Villas, Chester Road, Erdington, in the
County of Warwick, no occupation, 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:-—
This invention relates to new or improved portable ovens or boxes for heating
and drying purposes constructed and arranged as hereinafter described and shown.
Such ovens are intended for the purpose of heating or drying articles rapidly by
the aid of a gas jet, spirit lamp or similar handy means and more particularly
intended for heating or reheating flannels or poultices or other similar requirements
for the sick room.
In order to more clearly explain this my invention and the manner in which it is
to be performed, I have appended hereunto an illustrative sheet of drawings upon
which are figures and letters of reference, similar letters referring throughout the
several views to the same thing or part, and in which :-
Fig. 1, is an end view of this my invention, showing it open ready to receive the
article to be heated &c.
Fig. 2, is a cross section on line 5-5, (see Fig. 4) showing the oven closed,

page_text: Fig. 3, is a cross section similar to Fig. 2, but of a modified form of oven, having
internal removable sheets or partitions.
Fig. 4, is a plan view of the invention.
The oven or box consists of two similar or nearly similar parts A, A, which are
hinged together at B, which said hinge is of any desirable suitable form. The
plates C, C, are preferably corrugated for the better distribution of heat and for
strengthening the structure while the sides are made of a suitable depth to suit the
flannel &c. to be enclosed. D, D, are handles attached to the parts A, A, forming
not only the means for holding the closed oven, and for turning it about over a
flame or fire, but also for firmly keeping the box closed. E, represents the flannel
or other article enclosed in the oven, that is to be heated or dried.
In some cases it may be desirable that the flannel &c. E, should not come in
direct contact with the outer shell or plates C, C, in which case I provide removable
sheets F, F, one or both of which may be used, and which may consist of perforated
sheet metal or of woven wires or other suitable partition, which provides that a
space G, shall be formed between the said perforated partition and the external
shell plates C, C.
Also in some cases, with or without the removable sheets F, F, one of the
plates C, may be perforated whereby generated steam &c. may be given off when
the heating is taking place.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The new or improved portable oven consisting of two recessed parts A, A, (or
the one part may be only a cover) hinged at their one side, and having handles D, D,
substantially as described and shown in Figs. 1, 2 & 4.
2. The modified combination in a portable oven of the parts A, A, hinged at B,
and having handles D, D, with the removable parts F, F, as described and shown
in Fig. 3.
