PROVISIONAL SPECIFICATION.
Improvements in Roasting Shelves for Gas Ovens.
I, MARGARET ALICE ST. JOHN Carb, of 22, Old Bond Street, London, W.,
Professor of Voice Production and Singing and Vocalist, do hereby declare the
nature of this invention to be as follows :-
This invention relates to shelves used for roasting in ovens heated by gas, and
it has for its object a novel method of making such shelves, by which great
economy of heat is effected and the process of roasting is perfected, whilst space
is economized as other articles of food can be cooked at the same time that meat
is being roasted, and without affecting their flavour.
The shelves or gratings ordinarily used to hold meat whilst being roasted in gas
ovens, consist of flat gratings the bars of which are horizontal and extend from
side to side of the oven, but with such shelves the dripping from the meat runs
along the bars in both directions until it is stopped by the sides of the oven and
it then falls upon the gas jets below, by which the oven is heated, injuring the
burners of the latter, and causing a very objectionable smell of burning fat.
By my present invention I make the bars of the grating, which supports the
meat whilst being roasted curved downward at their centre so that the dripping
always runs down to the centre of the bars where it drops into a dripping pan
placed beneath.
Great economy of heat is effected by the use of my invention, as a perfect
process of roasting meat or other articles is obtained by placing them at a
regulated distance from the gas burners.
Moreover, space is available in the oven for at least two other shelves upon
which other articles of food may be perfectly cooked simultaneously with the
roasting of a joint of meat. Hitherto the most effective method of roasting in a
gas oven has been the suspension of the joints to be roasted by means of hooks
from the centre of the top of the oven.
This method necessitates the removal of all shelves and the oven must therefore
be entirely devoted to the cooking of one joint, waste of time and of heat being
thereby caused.
Labour in cleaning is economized, the cleanliness of the oven being preserved as
the drippings are directed by the curved bars into the centre of a dripping pan,
and away from the gas burners and the sides of the oven.
Apparatus constructed according to my invention is extremely simple, and very
effective for the purpose required.
Dated this 22nd day of October 1891.

Improvements in Roasting Shelves for Gas Ovens.
I, MARGARET ALICE ST. JOHN CARB, of 22, Old Bond Street, London, W.,
Professor of Voice Production and Singing, and Vocalist, 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 and
accompanying drawing, that is to say :--
This invention relates to shelves used for roasting in ovens heated by gas, and it
has for its object a novel method of making such shelves, by which great economy

economized as other articles of food can be cooked at the same time that meat is
being roasted and without affecting their flavour.
The shelves or gratings ordinarily used to hold meat whilst being roasted in gas
ovens consist of flat gratings the bars of which are horizontal and extend from
side to side of the oven, but with such shelves the dripping from the meat runs
along the bars in both directions until it is stopped by the sides of the oven and
it then falls upon the gas jets below, by which the oven is heated, injuring the
burners of the latter, and causing a very objectionable smell of burning fat.
By my invention I make the bars of the grating, which supports the meat,
whilst being roasted, curve downward at their centre so that the dripping always
runs down to the centre of the bars whence it drops into a dripping pan placed
beneath.
Great economy of heat is effected by the use of my invention, as a perfect
process of roasting meat or other articles is obtained by placing them at a
regulated distance from the gas burners.
Moreover space is available in the oven for at least two other shelves upon
which other articles of food may be perfectly cooked simultaneously with the
roasting of a joint of meat.
Hitherto the most effective method of roasting in a gas oven has been the
suspension of the joint to be roasted by means of hooks from the centre of the
top of the oven.
This method necessitates the removal of all shelves and the oven must therefore
be entirely devoted to the cooking of one joint, waste of time and of heat being
thereby caused.
The accompanying drawing is in illustration of my invention.
Figure 1 is a plan of the improved shelf or grating.
Figure 2 is an end view, and Figure 3 a side view.
Figure 4 is a perspective view of the shelf.
a, a, are parallel angle irons which rest upon ledges at the desired height in
the sides of the oven in the usual way. b, b, b, are the transverse bars the ends
of which are rivetted to the angle irons a, a¹, and which curve downward at their
centre as shown.
The bars b may be of rectangular or other desired section, and the extent of
their curve downward may be increased or diminished as may be found desirable.
Instead of being made, as shewn, of bars and angle irons attached together, the
entire shelf or grating may be cast in one piece.
Labour in cleaning is economized, the cleanliness of the oven being preserved
as the drippings are directed by the curved bars into the centre of a dripping pan,
and away from the gas burners and the sides of the oven.
Apparatus constructed according to my invention is extremely simple and very
effective for the purpose required.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
In roasting shelves for gas ovens, the bars b, b, b, curving down at their centre,
substantially as and for the purposes described and illustrated.
