This invention relates to an electric socket
construction adapted for holding an electric light
bulb.
An object of the present invention is to provide
a new and improved electric socket construction
for releasably holding an electric light bulb
therein in such a manner that the light bulb

pended claims.

socket construction is illustrated in the draw
struct the resilient metal lamp bulb-holding or
clamping members in such a manner that a lamp
bulb may be slidably inserted into the new sock
et among the said resilient metal lamp bulb
holding or clamping members and then secured
in position therein by imparting a slight rotative
movement to the lamp bulb. This slight rotative
movement of the lamp bulb causes the threads
on the base of the lamp bulb to threadedly en
gage portions of the said resilient lamp bulb
holding or clamping members which are so in
clined relative to each other that they follow the
pitch of the threads on the base of the lamp
socket and thus secure the lamp bulb in position
of use in the socket “ and against accidental or 45
unintentional dislodgment therefrom.
Other and further objects of the present in
vention will be apparent from the following de
scription and claims and are illustrated in the
accompanying drawings which, by way of illus
tration, show preferred embodiments of the pres
ent invention and the principles thereof and
what I now consider to be the best mode in which
I have contemplated applying these principles.

the same or equivalent principles may be used

the like. The socket casing or housing I! in
cludes a tubular portion i2 which is .adapted to

portion 55 vof the socket housing H is provided
at its lower end with an opening 49 for the pas

and a lower portion ‘22 which are held together in
“a manner which will be‘describe'd hereinafter.
The upper portion 2| of the supporting‘unit 20 is

seen‘that when‘ the two‘resilient lamp bulb-hold

‘of the’ ‘said two resilient lamp bulb-holding or

slidably mounted in this opening or passage ‘54.
The switch-operating and switch contact-sup

which is slidable in the opening or'pass'age .54.
L‘I‘he'saicl central portion 53 of the switch-operat

A relatively-stationary metallic contact mem

of the upper portion: 2 [of thesupporting unit 20,

of the lamp bulb 41 seats when the base 48 of the
lamp bulb 41 is mounted in the socket Ill.
As shown in Fig. 4, one of the lead-in wires
or conductors 26, to which the new socket l0
may be connected, is attached to the angularly
extending or hook-shaped lower end portion 59
of the resilient combination clamping and con-
6
thereof between and on opposite sides of the
headed lower end portion 51 of the stationary
upper contact 21 and the headed upper portion
58' of the lower stationary contact terminal 3|,
respectively, as the parts are seen in the draw

The manually operable and slidable switch

60 of a metal strip 34. This metal strip 34 is 10 ried thereby, will then be disposed in the posi
tion in which the parts are shown in Fig. 1 of

with the parts arranged in the positions shown
The electrical circuit through the new socket
and with the lead-in wire 35 electrically con
nected to the hook-shaped lower end portion 60 20 Ill and the lamp bulb 41 mounted therein will
then be completed as follows: from one of the
of the contact strip 34 and with the other lead

in wire or conductor 26 electrically connected
shaped lower end portion 59 of the resilient com
to the hook-shaped lower end portion 59 of
bination lamp bulb clamping and contact mem
the resilient combination lamp bulb-holding or
25 ber
clamping contact member Ho.
The metallic base 48 of a conventional elec
tric lamp bulb 41 may then be slid into position
of use in the portion 1 2 of the socket housing
II by manually sliding the same among the three
resilient lamp bulb-holding or clamping mem
bers |1-|1-|1a until the major portion of the
metallic base v48 of the lamp bulb 41 has thus
been projected among, and has been clamped
by, the three resilient lamp bulb-holding or
clamping members |1-|1—|1a which are spread
or forced apart against the force of their own
innate resiliency during this operation.
The
lamp bulb 46-41 may then be given a slight ro
tative movement (in a clockwise direction as
seen from the top thereof), whereupon the off
set or deformed portions |9 of the resilient lamp
bulb clamping members |1—|1—|1a will fol
low the pitch of the threads 46 on the metallic
base 48 of the lamp bulb 41 andthus force the
inner end portion of the metallic base 418 of the
lamp bulb 41 into a ?rm tight seating engage
ment and electrical contact with the three re
silient contact ?ngers 39 of the stationary con
tact member 28.
At this time the slidable contact-supporting
switch bar or rod 31—53 will be disposed in the
open circuit or open switch position in which
it is shown in Fig. 2 with the lower resilient con
tact arm 42 disposed out of engagement with
the headed upper portion 58 of the lower sta
tionary contact terminal 3|. However, the elec
trical circuit through the new socket l0 may be
completed, so as to illuminate the lamp bulb
|1a, through the latter, thence into and
through the metallic base 48 of the lamp bulb
41, into and through the ?lament of the lamp
41, then through the metal contact plate or disc
48a at the lower end of the metal base 48 of
the lamp bulb 41, into and through the resilient
contact arms 30'of the stationary contact mem
ber 28, thence through the upper stationary con~
tact terminal or rivet 21, through the upper
switch contact arm 43 and the bight portion 40
of the switch member 4|, thence through the
lower switch contact arm \42 into and through
the lower stationary terminal 3| into and
through the contact strip 34 and the hook
shaped lower end portion 60 thereof back into
40 the other lead-in wire or conductor 35, thus com
pleting the circuit through the socket II and
thereby illuminating the lamp bulb 41 held
thereby.
It will be noted that when the slidable switch
45 operating bar or rod 31 and the switch unit 4|
carried thereby are thus disposed in closed cir
cuit position, as in Fig. 1, the switch-operating
bar 31 and the switch unit 4| carried thereby are
held in closed switch or closed circuit position
50 by the latching engagement of the recessed por
tion 44 of the upper resilient switch contact arm
43 with the headed lower end portion 51 of the
upper stationary contact terminal or rivet 21,
However, when it is desired to open the circuit
55 through the new socket l0 this is readily accom
plished by pressing the slidable switch-operat
ing bar or rod 31 to the left from the position in
which the parts are shown in Fig. 1. This op
eration moves the lower resilient switch contact
41 mounted therein, by manually pressing the
switch-operating and contact-supporting slide 60 arm 42 of the switch unit 4| out of engagement
with the headed upper portion 58 of the lower
bar or rod 31—53 to the right, as shown in Fig. 2,

thereby moving the lower switch contact arm 42
the circuit through the socket l0.
into engagement with the headed upper portion
It will be noted, however, that as the switch
58 of the lower stationary contact terminal 3|.
During this operation the upper resilient switch 65 operating and switch contact-supporting mem
her or rod 31 is thus moved to the left, from the
contact arm 43 slides under the lower headed
end portion 51 of the upper stationary contact
terminal 21 and the said headed lower end por
tion 51 of the upper stationary contact terminal
21 seats in the recessed portion 44 of the upper
resilient switch contact arm 43. During this
movement of the slidable switch contact support
ing and operating bar or rod 31 the latter is
position which the parts are shown in Fig. l,
the headed lower end portion 51 of the upper
stationary contact terminal 21 comes into latch
ing engagement with and seats in the recessed
portion 45 of the upper resilient switch arm 43.
When the parts are so disposed the recessed por
tion 45 of the upper resilient switch arm 43 thus
cooperates with the headed lower end portion 51
slidably guided by movement of the upper ?ange
portions 56 and the lower ?ange portions 55 75 of the upper stationary contact terminal 21, to
