I, LOUIS JOSEPH QUÉNOT, of Plateau d'Avron, Commune de Neuilly, Plaisance,
Department of the Seine et Oise, France, Merchant, do hereby declare the nature
of this invention to be as follows;
-
My improvements are designed to provide ovens in which all kinds of food can
be caused to revolve and thus become thoroughly and efficiently cooked, without
contact with the fire, and without the necessity of opening the oven and thus lower-
ing the temperature.
My improved oven has a door with a large glass panel permitting one to inspect
the food when being cooked. Inside this oven rotates a metal frame of oblong
shape mounted on a spindle revolving on suitable bearings. One end of this spindle
projects through the oven and is rotated by a motor of some suitable kind. One
end of the frame is furnished with spikes and at the other end is a sliding bar also
fitted with spikes. The meat to be cooked is placed within the frame and held by
the spikes. My improved oven has a double exterior casing with an air chamber on
all sides and on top and bottom, the door or windows only excepted.
Beneath the revolving spit or spiked frame before described is a circular metal
plate on which dishes with food can be placed. This plate or disc is also caused
to revolve when required by means of a light gearing which is operated from the
spindle of the spit.
Any suitable motor can be employed, the most convenient being one containing
a coiled spring, which can be wound up with a key.

page_text: this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
My improvements are designed to provide ovens in which all kinds of food can
be caused to revolve and thus become thoroughly and equally cooked without
contact with the fire, and without the necessity of opening the oven and thus lower-
ing the temperature and thereby injuriously affecting the quality of the meat.
My improved oven has a door with a large glass panel, permitting the food to be
inspected while being cooked.,
Inside this oven rotates a metal frame of oblong shape, furnished with journals
revolving on suitable bearings.
At one end the journal projects through the oven and is rotated, by a motor of
some suitable kind. One end of the frame is furnished with spikes and at the other
end is a sliding bar also fitted with spikes. The meat to be cooked is placed within
the frame and held by the spikes.
My improved oven has a double exterior casing with an air chamber on all sides
and on top and bottom; the door or window only excepted.
'
Beneath the revolving spit or spiked frame before described is a circular metal
plate on which dishes with food can be placed. This plate or disc is also caused to
revolve when required by means of a light gearing which is operated from the
spindle of the spit.
Any suitable motor can be employed, the most convenient being one containing a
coiled spring which can be wound up with a key, or a train of geared wheels operated
by a weight.
I will now describe my invention with reference to the accompanying drawings
in which:-
I
Fig. 1 shows a front elevation of one form of my improved oven, with the, door
open and partly in section.
Fig. 2 shows a sectional plan of same.
Figs. 3 and 4 shew sectional elevations of two other forms.
a, b, c, d are the four sides of a rigid metal frame forming a spit and containing
the fixed spikes f, and moveable spikes: h fastened to the sliding bar which is
fixed in any position by means of the screws V. A similar sliding, bar can be
fixed at the other end if preferred. ....
:
T
The frame a, b, c, d has journals e, m, one at each end: The frame can be made
adjustable if preferred and the parallel bars b d may be caused to approach each
other.
1.
C, is a revolving horizontal plate operated by the gearing u, t, S. On this plate
cakes and other viands can be cooked.
"
R, is a spring bottle jack or motor hereinafter described, for rotating the spit.
J, is the joint or other viand, which is securely held between the spikes f, h.
Spoons or ladles can be fixed to the sides of the frame b, d, so as to scoop up
gravy from a dish below (see Fig. 1.)
.
The journals of the spit a, b, c, d, are supported on the bearings p, p, fixed to the
plate Qwhich is mounted on feet sufficiently long to keep it above the plate C.
The journal e has an angular end which fits into the cylindrical boss K, which
passes through the side of the oven and is rotated by the motor employed. A
similar device is employed to rotate the plate C
*
The plate C, may be operated by the same device as that which rotates the spit,
by means of a band and pulley r, Fig. 1, or a separate motor may be employed.
A more simple form of connecting the two movements is shown in Figs. 3 and 4
by a chain passing over the pulleys A¹, B',, D¹.
P is the door with a glass pane G through which the viands can be seen while
being cooked.
Instead of glass several small openings fitted with mica or other substance may be
. employed.
The metal grating T protects the mica or glass from the heat of the oven.
i

page_text: The operation of the motor R is as follows:-
R is a casing containing a coiled spring which rotates a vertical shaft R¹ project-
ing through either end of the casing. The downwardly projecting portion drives
the spit and the upwardly projecting portion is fitted with a device adapted to
sound an alarm such as by ringing a gong, to indicate when the spring motor
requires rewinding. The alarm device consists of a pair of suspended balls which
operate a sleeve R2 in the same way that a steam engine governor is operated. The
sleeve R is provided at its lower end with two projections, which, when the sleeve
is revolving in its lowest position strike alternately against an arm R³, pivotted on
the casing R at one end and having a clapper at the other end which strikes against
a gong mounted adjacent thereto on the casing R.
Any suitable motor and alarm may however be used.
At whatever side of the oven the fire is stationed, the viands will, in consequence
of their movement, present their whole surface in rotation to the fire.
Another form of my apparatus is that shown in Fig. 3 wherein the joint is
attached to a revolving vertical rod E¹ which enters the oven from the top and can
be rotated by any motor power preferred.
Instead of the vertical rod E an arched rod F¹ may be employed which could
be attached to the revolving plate C so that it would rotate and carry the joint
with it.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
1. The combination of an oven with appliances for fitting the back or end and
bottom of same with cylindrical bosses into which the journals of a spit a, b, c, d, or
of a plate C can be introduced so as to enable the viands cooking in the oven to be
rotated without opening the door of the said oven, the bosses K and E, furthermore
being capable of being set in motion by any motor or gearing preferred, as herein
described and set forth.
2. A spit composed of a frame a, b, c, d on which is the sliding bar g fitted with
screws V, and spikes h, the said frame having the two journals m, e, one of which fits
into the boss K, as herein described and set forth.
3. In combination with the spit a, b, c, d, a plate fitted with two supports p, p, on
which the journals m, e, rest, as herein described and set forth.
4. A door P fitted with a glass pane or transparent opening protected by a
grating T, as herein described and set forth.
5. An arched rod or support F1 attachable to the plate C, so that substances to be
cooked may be hung from it and rotated, as herein described and set forth.
