PROVISIONAL SPECIFICATION.
Improvements in Cooking and other Ovens.
We FREDERICK DYE and JOHN WELLS of 176, Regent Street, London W.
Engineers do hereby declare the nature of this invention to be as follows:-
:-
This invention relates to improvements in cooking and other ovens and refers
particularly to such ovens as have glass panels in the doors for the purpose of
rendering the interior and contents visible without necessitating the opening of the
oven door.
The object of this our present invention is to overcome the difficulty hitherto
experienced in such ovens by reason of the sheet of glass fracturing upon a certain
teinperature (generally about 300°), being attained. This heat causes a distortion
by way of convexity on the inside of the glass and the fracture occurs; and to
obviate this objection we in accordance with this invention, divide the sheet of
glass into sections a convenient number of such sections being four, but a greater or
less number may be employed if found desirable, and hold said sections together
centrally by means of a screwed pin passing therethrough and nuts and washers.
When so preferred the edges of the sections of the sheet of glass may be covered or
supported by a cross framing, and the glass secured therein by suitably shaped
pieces of metal slipped on to the inner rib of the framework and pressing upon the
glass. The ends of these pieces of metal upon the insides which press upon the
glass may, if desired, be lined with a soft material or substance such as asbestos
or the like.

Improvements in Cooking and other Ovens.
We FREDERICK DYE and JOHN WELLS of 176 Regent Street London W.
Engineers do hereby declare the nature of this invention and in what mauner
the same is to be performed to be particularly described and ascertained in
and by the following statement :-
This invention relates to improvements in cooking and other ovens and refers
particularly to such ovens as have glass panels in the doors for the purpose of

oven door. The object of this our present invention is to overcome the difficulty

distortion by way of convexity on the inside of the glass, and the fracture occurs,
and to obviate this objection we in accordance with this invention divide the sheet
of glass into sections a convenient number of such sections being four, but a greater
or less number may be employed if found desirable.

page_text: And in order that this our invention may be fully understood we will now
describe same with reference to the accompanying sheet of drawings upon which
Fig. 1 represents in front elevational view an oven door with four sections of
glass held together centrally by means of a screwed pin passing therethrough and
nuts and washers. Fig. 2 is a vertical section through line A. B. Fig. 1.
Fig. 3 is a front elevational view of a glazed oven door in which the sections of
glass are supported or carried in a suitable cross framing.
Referring particularly to Figs. 1 & 2 aa aa are four sections of glass panelling
provided in the oven door for the purposes above specified c is a screwed pin
passing centrally through the four sections a. d d are washers and e is a nut for
tightening up as may be required. Each of the four sections of glass a has a corner
suitably cut away or shaped to permit of their being when all the sections are placed
together in position a central aperture through which the pin c may pass as above
described.
In Fig. 3, f, is the cross framing above alluded to in which the four (as shown
or other desired number of) sections a a are supported. The glass may be secured
in the cross framing by suitably shaped metal clips pressing upon the glass. The
ends of these clips which press upon the glass may if desired be lined with a soft
material or substance such as asbestos or the like.
It will of course be understood that other means of supporting or carrying the
desired number of sections of glass than those illustrated in the accompying
drawings all as circumstances may render convenient may be employed and this
without departing from this our invention which consists essentially in forming the
glass panels of oven doors in a suitable number of sections to allow of expansion
and contraction in accordance with the temperature without breakage of the glass
panel hitherto so frequent a cause of annoyance and inconvenience in glazed oven
doors.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is
1. The improvements in cooking and other ovens substantially as herin before
described and illustrated in the accompanying drawings.
2. In cooking and other ovens having glazed doors for the purpose of
rendering the interior and contents visible, the construction of such glazed portion
of the door in a suitable number of sections to permit of expansion and contraction
according to variations in the temperature without fracture of the glazed portion of
the oven door substantially as herin before described.
