Within
the opening in the head of the sleeve there is a
ñXed center contact 22 of familiar form held by
the axial bolt 23. The inner end of the re
ceptacle is formed with a recess 24 opposite the
socket, and spaced from the lug 20 and blade,
are both disposed at the same side of the de
in which there is set snugly the base of a switch
arm 25, bent over its base and normally bearing
against the contact ilange I5’. The switch arm
is formed with a nodule 26 adapted to engage
vice, and arranged to engage respective end porw
tions of the plate I4, which is apertured in its
upper part where the blades overlap it, and each
blade is formed with a nodule to engage the ap
erture, making for better contact as Well as ef
serving as a means to prevent the opening of
fecting yielding retention of the switch in closed 20
position. The blades 2| stop short of each other
sufliciently to enable ready mounting of the wire
20 yieldingly in the aperture in the ilange I5’ and
Ythe switch casually. The bolt 23 is extended
through the base of the switch arm 25 and re~
ceives a nut as shown whereby the arm 25 and
contact 22 are held in assembly. An additional
slot 21 parallel to the one 20’ may be formed
through the head of the socket of the receptacle
on the opposite side of the axis of the receptacle
from the one through which the lug 20 is en
30 gaged, though only one slot is used in each re
25
ceptacle. This permits the receptacle bodies to
be used interchangeably, however, as one slot is
used at one end of the device and the other
slot is used when the receptacle is mounted at
35 the other end of the device.
The body of the receptacle is formed with
a plate 28 projected longitudinally from its inner
end over the outer side of the wall I3, this plate
being flush with and formed as a continuation of
4 O the ñattened side of the receptacle body. On
the inner side of the plate 28 near its extremity
a pivot yoke 29 yis secured by screws 29’ extended
from the outer side of the plate 28. The yokes
are U-shaped and have ears extending on each
side of the wall I3, suitable pivot pins being
engaged through the ears and wall I3. The ears
»on the yokes 29 are long enough to allow the
plate 28 to clear the wall I3 suiiiciently for the
pivotal movement of the receptacle, as desired.
Two receptacles are pivoted on the block I2
extending in opposite directions and the pivot
pins are likewise sufiiciently spaced longitudi
terminal therebetween.
In use, the device being assembled as described,
the fixture may be mounted in various conñned . ‘
locations, as, in reading lamps, show window ñx
tures, show case corners, in drawers, refrigerators,
etc. Being secured in place, the receptacles are
alternately operated by grasping the sides of the
broadened side of the receptacle body and drawing
it outwardly from the case IIJ, to the special or
open position, so that the lamp 31 may be in
serted. This done, this receptacle is pressed back
to normal position and the operation repeated
with the other receptacle. As each receptacle is
drawn outward, the switch blade 2| moves out
ward on the plate I4 without clearing it however.
while the switch arm rides on the insulation out
wardly of the contact flange I 5’ on the end of the
wail la. At the outermost position the nodule 2s «140
will engage outwardly oi' the angle between the
top or outer edge face of the wall I3 and the end
face thereof to yieldingly hold the receptacle in
open position conveniently i'or removal of the
lamp or replacement thereof.
The engagement 7
of the springs 3| will tendv to prevent careless
operators from abruptly forcing the receptacles
outwardly to such limit as to break the porcelain
or other insulation material.
