This invention relates' to a terminal receptacle

As therein more fully described,‘it is necessary
in oven light structures of this character, that
the bulb shank and electric socket be exposed
l0'1‘to the outside ‘air in a manner such that there is
free circulation ‘of airgthereabout to cool the bulb
and socket and preventheating of the bulb shank
andisocketto a dangerous degree. In order to
obtain adequate ventilation and cooling, it is nec
15 ‘essary tomount the socket entirely‘ outside of

In additionto‘the- oven-light'above described,
it has‘become vcustomary practice to provide illu-~

also'electrical electrical clocks, and‘ other elec
ed in position for illuminating the top of the

An electrically operated-clock 6 is mount- '

thereof'may be‘rendered'accessible readily to the
operator to permit the bulb to be changed in the
usual manner without danger'of short circuiting
against the metal’ of ‘the ‘range or in any other
50 manner during the installation or removal
thereof.
Other objects and ‘advantages will become ap
parent from the following speci?cation wherein
reference ismade to the drawings, in which:

Fig. 1 is an end elevation of the range with a.
!3 so that the ‘entire top panel l2 may be lifted ‘
to a vertical position to permit access to the serv
ice burners for cleaning and repairs.
In the range in connection with which the 401::
present invention is illustrated, the oven has a
rear wall IS in which is a suitable aperture I6,
a metal liner or sleeve I‘! being provided to line
the aperture. The liner I‘! is' provided atits
inner end with a slightly inturned peripheral
flange l8 which defines an annular abutment
which is preferably slightly less in diameter than
the bulb to be associated with the aperture so '
that the bulb may be‘ seated from' the outside
against the flange 18 and thus protrude slightly
into the interior of the oven but without danger ‘
of passing entirelythereinto‘. Mounted on the‘
rear wall of the oven is one arm 2!!v of ‘a suitable‘
hinge, the other‘arm 2| of which extends nor
mally a predetermined ‘distance from the rear '55:,

of the range. Mounted on the arm 2| in spaced
relation to the rear wall of the range is a ter
minal receptacle 22. As illustrated, the recep
tacle 22 preferably is comprised of imperforate
sheet metal and is provided intermediate its ends
tor and all parts are so arranged that there is no
dangerous ?exure of any wire or connection dur
ing opening and closing of the receptacle 22.
Having thus described my invention, I claim:
1. In a range having an oven compartment with
with a sub-compartment 23 in which are carried
a rear wall having an aperture therein and a
the usual sockets 24 for receiving saber connec
tions. Below the compartment 23 in the box 22
is a push button switch 25 which is rigidly
10 mounted in the box and has the usual push but
door for said compartment, a closed receptacle,
hinge means connecting the receptacle to the rear
wall of the oven and supporting the receptacle
in rearwardly spaced relation therefrom, a socket
ton 26 extending outwardly therefrom towards
carried by said receptacle in rearwardly spaced
the rear wall of the oven.
Mounted within the receptacle at the upper or
relation from the oven wall, an electric bulb car
opposite end thereof is a light socket 28, the light
15 socket being ?xedly secured to the front wall of
the receptacle 22 and extending forwardly thereof
so as to be accessible from the front thereof.
Carried in the socket 28 is a bulb 29 which, when
the receptacle is in an upright position, seats
20 against the ?ange l8 of the liner H. The recep
tacle 22 is held in upright position by a suitable
tension spring 39 connected at its ends to the rear
wall of the even, as illustrated, and looped around
the receptacle. The force of the spring 30 is re
25 sisted entirely by the bulb 29 engaging the ?ange
l8. Suitable lead-in wires 33 extend through an
opening in the bottom wall of the receptacle 22,
and are protected within the receptacle opening
ried in said socket and extending forwardly there
from and seated in said aperture when the re
ceptacle is in one position, a switch carried by 15
the receptacle and having an operating button
extending forwardly therefrom, electrical connec
tions between the switch and the socket within
the receptacle'and lead wires connected in said
circuit and extending through a wall of said 20
receptacle and being arranged for connection to
a source of current, operating means carried by
the range and operative consequent upon move
ment of the door to open position to cause actua
tion of the switch for lighting the bulb, and oper 25
able upon moving of said door to closed posi
tion for breaking the circuit to said bulb.
2. In a range having an oven compartment with
by a suitable cushion 34 so as to eliminate any
a rear wall and an aperture in said rear wall, a
30 danger of abrasion of the lead-in wires by the
edges of the opening. In order to protect the
socket and other connections within the box from
any pull occasioned by pulling the wires 33, the
lead-in wires are knotted, as at 35, in the box,
35 ‘thus providing a suitable anchor. The sockets 24
are connected in parallel to the lead-in Wires 33.
The switch 25, on the other hand, is connected in
series with the socket 28 and with the lead-in
wires 33. The switch is so positioned that the
button 26 is movable horizontally fore and aft of
therange just above the floor of the oven.
An operating rod 38, carried by the range, ex
tends from the button 2'6 to the front of the range
in position to be engaged by the door 3. The
switch is arranged to complete the circuit to the
light when the door is in open position and to
break the circuit through the medium of the rod
38 when the door is moved to closed position.
For this purpose the outer end of the rod adjacent
50 the front of the range is positioned in such man
ner as to be engaged by the door 3 itself upon lift“

ing thereof to closed position.

switch means and the socket, lead wires connected
in a circuit with the switch means and socket,
and means yieldably urging said receptacle into
a position to hold the bulb seated in said aper

posed in spaced relation to the rear wall of the
oven.

of the oven and supporting the receptacle in

It will be seen that the socket 28 and the shank
65 of the bulb 29 are positioned entirely in the open
behind the oven wall and out of contact there
with so as to be ventilated freely and thus pre
vented from reaching a temperature which might
be dangerous to the bulb or socket. Furthermore
70 there is no metal to metal conduction'of heat from
the range into the socket and bulb shank. The
same is true as to the plug-in sockets 24 and
switch 25. In addition, all incidental electrical
connections are entirely protected both from the
75 heat of the oven and from exposure to the opera
ranged for connection to a source of current, op 65

into a position to dispose the bulb in said aper
ture with the bulb socket and shank of the bulb
exposed in spaced relation to the rear wall of the
oven.
