FOLDING ELECTRIC‘ STOVE
Constantine P. Lent, New York, N. Y.
Application February 11, 1936, Serial No. 63,304
9 Claims. (Cl. 219-19)
This invention relates to the class of electric
stoves and particularly to a type of folding elec
tric stove.
One object of the invention is to provide an
5 electric stove comprising two separate electric
heating, elements mounted inside a container re
sembling a suitcase or travelling case, the latter
having two hinged sections which connect to
gether when folded.
10
A further object of this invention is to provide
anwelectric stove that is comparatively simple of
manufacture and safe to operate.
Afurther object is toprovide a folding stove
having means to enclose all operating parts, such
15 as heating elements, wires, switches and the like
within said container when the latter is folded
or closed up.
A further object is to provide space within said
container for the storing of utensils when said
20 container is folded up and not in use.
Further objects will be seen as the description
of the invention proceeds.
Referring to the drawing:
Fig. 1 is a plan view of the folding stove in
25 open position.
Fig. 2 is a section through the stove on a line
2—2 of Fig. 1, showing one hinged side of said
stove in‘ section and an exterior view of the op
posite side section. There is also shown the wire
30 wound slidable wire connection extending across
from one'side section to the opposite side section
thereof.
Fig. 3 is an outside view of the stove when in a
folded‘ or closed position.
35
Fig. 4 is a diagrammatic view illustrating the
wire connections of both heating elements in the
stove aforesaid.
Fig. 51s a section on a line 5-5 of Fig. 1 show
ing the manner of protecting the Wire connection
40 by means of a coiled spring reinforcement.
Referring toFig. 1, the numeral I0 is the body
of the folding stove proper. Said stove consists
of a folding side section or member i l and an op
posite side section or member i2.
45
The side section II and also section l2 have a
?anged box like form, each section having a bot
tom 13 and sides l4, I5, H5, and H. The aforesaid
sides of the box H are preferably formed up of
a solid piece of sheet metal. As an alternative
50 method of- manufacture the said sheet metal may
be bent up and the corners llb spot welded with
angle iron reinforcements.
A top plate or tray [8 having upwardly ex
tending side sections I9, 2B, 2!, and 22 is set over
55 the open portion of the box sections II and I2.
The top plate I8 is provided with a ?anged open
ing 23 into which the ?ange 24 projects below
the top surface 25 of the plate l8 and forms a
step‘26 as shown in Fig. 2. A heating element
21 is mounted inside the opening 23 and is held
in place by means of the screw 28 which is
screwed into a W-shaped bracket support 29.
The said bracket support serves to support the
top plate l8 and preventing the same from sag
ging by means of the protruding sides 30.
The top plate l8 or tray which is rectangular
in shape is, either held in place by means of
screws 3| or spot Welded to the body of the side
sections ll’ and 12. The said top plate is sunk
below thelevel of the top edge of the respective
side sections H and I2.
A switch 32 is mounted in convenient posi
tion on the'top plate l8. The switch 32 is pro
vided with‘ a shield plate having marks affixed
thereon. Such'marks may read “Off” and “On” ,_
indicating whether the switch is on “on” or “off”
position. Inv the event the switch 32 is of the va
riable type, the readings on the shield plate will
correspond to the settings of said switch. rl‘he
readings aforesaid may indicate “Off”, “High”,
“Med”, and “Low” setting positions. A switch 32a
similar to switch 32~is provided in section l2 to
switch'current on and off for the heating ele
ment 21a. The switches 32 and 52a are mounted
in position below the level of the top edge of the
respective sections II and I2.
The power wire 33 is connected to the stove
heater element through an insulated opening 35.
A reinforced spring 34 is loosely wound around
the wire for added ?exibility and protection
against contact or abrasion.
To facilitate electrical connection from one side
section to the opposite side section of said stove
there is provided the wire wound insulated wire
connection 31. One terminal of said wire con 410
nection enters the box section I I at the insulated
opening designated as 38 (see Fig. 5) and the
opposite terminal of said wire connection enters
the box section l2 through the insulated open
ing 39. The wire wound spring reinforcement
40 is wound loosely around the insulated wire
connection to protect said wire connection from
wear or abrasion.
spring reinforcement 40
is provided with insulated ?anged terminals 4|
and 42 as shown in Figs. 3 and 5.
When said adjacent sections II and I2 are
folded, the wire wound reinforcement section 40
of the wire connection slides through the bush
ing 38 (see Fig. 5) and into the inside of side
section II as shown in Fig. 2, and when said
2
2,105,814
adjacent sections H and I 2 are opened the wire
wound reinforcement 40 slides outwardly through
the bushing 38 aforesaid.
Referring to Fig. 4, the stove heating elements
2'! and 27a are wired in parallel. The main lead A
multiplies into leads B and C. The current from
the outside leads A ?ows in multiple through the
lead B to switch 32 and from said switch through
wire lead D to the heating element 21. Likewise,
the current from the main lead A ?ows through
lead C, wire connection 31 to the switch 32“ and
from thence to the heating element 21*‘. Both
heating elements work independently of each
other.
Insulated legs or the like are provided to pre
vent possible short circuit and also from scratch
ing surfaces upon which the stove may rest.
There are also provided ventilating vents 44
which serve to reduce the temperature inside the
stove and underneath the heating elements.
The stove box sections H and I2 can be ?lled
up with some manner of insulated material such
as asbestos or the like to prevent the overheating
of the respective bottoms [3 of said box section.
Sufficient space is provided between the tray
tops 58 in the event that the stove container side
sections are folded to accommodate as storage
a toasting rack or broiling pan, the latter being
utilizable with this type of heater when the said
30 stove is opened for operation,
A carrying handle 45 and lock 46 are provided
as shown. Hinges 41 and 4B are preferably spot
welded to the sides l1, lla of the side box con
tainers l I and I2. The hinges aforesaid may
also be screwed on to the side sections aforesaid.
As stated, the spring reinforcement is provided
to protect the wire connection from wear or
abrasion.
Said spring reinforcement slides out
of the box members when opened and said spring
40 slides inward into said box members when said
.box members are folded together.
In this manner the wire connection may be
contained within the box members when the lat
ter are closed, and as a consequence substantial
45 protection to said wire connection is afforded
when said stove is folded up and in shape to be
carried by hand or is being transported.
It is understood that modi?cations from the
foregoing description are possible, and I therefore
50 do not desire to limit myself to the strict interpre
tation of the text aforesaid, but limiting myself
only by the scope of the appended claims.
