bolts or lugs 32 secured in any suitable manner
to the rear wall I5 of the stove il.
Rlgidly secured in any desired manner to the
rear wall I5 is a U-shaped member 33 which,
This invention relates to stoves and more par
ticularly to'two-fuel oven combustion stoves.
A principal object of the invention is the pro
vision of means for simultaneously opening a
5 normally closed secondary air inlet to and ñue
outlet from the oven of such a stove when gas
is used as a fuel for heating the oven.
Another important object of theinvention is
the provision of operating means for such open
10 ing means, which will simultaneously control the
fuel supply to the ov'en burner or the broiler
burner of the oven.
.
Numerous other objects and advantages of the
invention will be apparent as it is better under
stood from the following description, which, taken
in connection with the accompanying drawing,
discloses a preferred embodiment thereof.
`In the drawing,
-
with lsaid wall, constitutes the` lower portion of Ul
the usual flue that leads to a stack (not shown),
and has a clean-out aperture 34 conveniently lo
cated therein and normally closed by a plate 35.
Adjacent the plate 29, the member 33 is or may
be provided with a laterally extending lug 36
Aadapted to assist in maintaining the plate 29
against the rear wall ‘I5 and, together with the
slot 3l and pins 32, in guiding it in its vertical
movement, the function of which will be later
described.
'
.
An -aperture 31 is provided in the upper part
of the rear wall I5 which constitutes a ñue out
let or opening from the oven I2 to the flue de
lined by the 4wall I5 and the member 33. The
Figure 1 is a rear elevation of a stove embody
ing the invention, with part of the clean-out> flue outlet 31 is normally closed by a plate or- 0

member 38. An extension 39 of the plate 38

and
«
Fig. 3 is' a‘detail horizontal section taken sub
stantially on the line 3-3 of Fig. 1.
Referring more particularly to the drawing, a
_ stove of any desired construction is indicated
30 generally by reference numeral I I, and -comprises
a two-fuel oven I2 of known construction having
a door I3 at the front, side walls I4, a rear wall-
I5, which extends laterally to form the rear
wall for the whole stove, a broiler burner I6 ad
35 jacent the top, and an ogen burner I1 in the bot-v
tom thereof.
`

Fuel'is supplied to the broiler burner I6 and
oven burner I1 by pipes I8 and I9, respectively,
which are controlled by a two-way valve mecha
40 nism 2l, of any desired construction, connected
to a main supply pipe 22. 'I'he valve 2| is con
trolled by a rod 23 suitably mounted for rota
tion in the frame or walls _of the stove II and
having an operating handle 24 secured to its
45 forward end,~whereby the direction of rotation
of handle 24 will determine whether fuel will be
supplied to oven burner I1 or broiler burner I8.
Rigidly Asecured to the vrodl 23 adjacent the
`valve 2I is one end of a lever 25, the other end
50 of which is pivotally secured to the upper end
the member 39. The protruding end of the ex 25
tension 39 co-operates with a suitable hole in the
upper end of a vertical extension 4I of the plate
29 so that when the plate 29 is in its lower or
normal position, as illustrated, it will maintain
the plate 38 in a substantially horizontal posi
tion to keep the ilue outlet 31 closed, and when
plate 29 is raised, plate 38 will drop or be forced
clockwise about its pivot point to open the flue
outlet 31. In its lower position the plate 29 is
also adapted to cover an aperture 42 in the rear
wall I5 which constitutes a secondary air inlet
5
to the oven I2 which will be opened when the
plate 29 is raised.
'
When neither the oven gas burner I] nor the
broiler burner I6 is in use, the secondary air in 40
let 42 and the nue outlet 31 are closed. In order
to use either the burner I5 or the burner I1,
handle 24 is rotated in one direction or the other,
respectively, thus actuating the two-way valve
2I in known manner.
Simultaneously with any
actuation in either direction of handle- 24, rod
23 actuates levers -25 and 25 to raise plate 29 to
open the secondary air inlet 42 and the flue out
let 31.
‘
of a depending lever 25, the lower.end of which
It is thought that Ãthe invention and many of 50
its attendant advantages will be understood from
is pivotally connected at 21 to a horizontal ex
tension or lug 28 on a plate member 29. The
plate member 29 has a vertical slot II therein
which engages and co-operates with a pair of

invention or sacrificing all of its material advan
tages, the form hereinbefore described being
merely a preferred embodiment thereof;
‘I claim:
1. In a stove having an oven, an oven burner, a
broiler burner in said oven, a secondary air inlet
p to said oven, a member normally closing saidsec
ondary air inlet, a flue outlet from said oven,
and a second member normally closing said flue
10 outlet; a'valve member operable in one direction
to control the fuel supply to said oven burner
and operable in the other direction to control the
fuel supply to said broiler burner, and connecting
devices between said valve member and said first
member and between said ñrst member and said
second member for operating said ñrst and sec
ond members simultaneously to open said second
ary air inlet and said flue outlet when said valve
member is operated in one direction or the other
20 to supply fuel to said oven burner or said broiler
burner.
for said burners, a valve controlling said fuel
supply operable when turned in one direction to
supply fuel to the oven burner and operable when
turned in the opposite direction to supply fuel to
the broiler burner, means connecting said damper
to said valve whereby said damper is moved to
open position when said Valve is turned to supply
fuel to either of said burners.
3. In a stove having an oven, an oven burner,

wall of said oven, a member normaly closing said
aperture, a flue outlet from said oven, and a sec
ond member normally closing said flue outlet; a
valve member operable in one direction to control
the fuel supply to said oven burner and operable 15
in the other direction to control the fuel supply to
said broiler burner, and a connecting device be
tween said valve member and said first member
and between said ñrst member and said second
member for operating said first and second mem 20
ber simultaneously to open said aperture and said
flue outlet when said valve member is operated
2. In a stove having an oven, an oven burner
