Abstract
Abstract An electrical outlet system in which an outlet box includes integrally formed connectors comprised of wells formed of insulating material and releasable conductive springs to receive and retain conductors and lateral grooves on opposed end walls adapted to be engaged by like opposed outwardly extending ribs on the ends of an electrical device such as a switch. One end of the electrical device includes an adjustment to releasably lock the device in the box. An extender for the box is provided with opposed dovetail tabs which serve to coact with dovetail grooves near the top of opposed side walls on the box. The extender may be installed or removed by moving its other opposed walls together.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
67 words
Electrical apparatus comprising in combination; an open ended housing including at least one inwardly opening parallel, groove in opposite walls thereof adjacent said open end; and current utilization means including spaced apart end walls having complimentary positioned end portions with at least one outwardly extending rib in engagement with the grooves in said housing, one end of said last named means being adjustable longitudinally of said means.
Claim 2
Dependent Claim
67 words
Electrical apparatus comprising in combination; an open ended housing including at least one inwardly opening parallel, groove in opposite walls thereof adjacent said open end; and current utilization means including spaced apart end walls having complimentary positioned end portions with at least one outwardly extending rib in engagement with the grooves in said housing, one end of said last named means being adjustable longitudinally of said means.
Claim 3
Dependent Claim
25 words
The apparatus of claim 1 in which the end portions on the current utilization means are comprised of a pair of laterally spaced apart columns.
Claim 4
Dependent Claim
21 words
The apparatus of claim 2 in which the opposed parallel grooves are divided into a pair of laterally spaced apart columns.
Claim 5
Dependent Claim
39 words
The apparatus of claim 3 in which said one end of the current utilization means includes a tapered groove and a wedge operable therein to longitudinally extend said one end to lock and unlock said means in the housing.
Claim 6
Dependent Claim
38 words
The apparatus of claim 2 in which one end of the current utilization means includes a tapered groove and a wedge operable therein to longitudinally extend said one end to lock and unlock said means in the housing.
Claim 7
Dependent Claim
35 words
