Abstract

Abstract An electrical unit, system or circuit includes a conventional switch and a novel outlet receptacle having, in addition to the usual pair of slots with contacts, a third slot with a contact which is electrically connected to a switch contact whereby an external connection from the latter slot and one of the pair of slots will complete the circuit as though the switch had been closed. Novel electrical devices are designed to establish this external connection.

Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 153 words
An electrical system for connection to two incoming wires from a power source and also for connection to two outgoing wires to a power consumer, comprising in combination a switch and electrically connected thereto an outlet receptacle having therein three asymetrically located slots each having an electrical contact means for contact with a prong when inserted in the slot, two of said slots constituting a pair and being positioned to receive a conventional electrical plug, the contact means of the third slot being electrically connected to one of the switch contacts and also having wire engaging means for an outgoing wire, the other swItch contact being electrically connected to the contact means of one of said pair of slots and also having wire engaging means for an incoming wire, the other one of said pair of slots having wire engaging means for the other incoming wire and also for the other outgoing wire.
Claim 2
Dependent Claim 153 words
An electrical system for connection to two incoming wires from a power source and also for connection to two outgoing wires to a power consumer, comprising in combination a switch and electrically connected thereto an outlet receptacle having therein three asymetrically located slots each having an electrical contact means for contact with a prong when inserted in the slot, two of said slots constituting a pair and being positioned to receive a conventional electrical plug, the contact means of the third slot being electrically connected to one of the switch contacts and also having wire engaging means for an outgoing wire, the other swItch contact being electrically connected to the contact means of one of said pair of slots and also having wire engaging means for an incoming wire, the other one of said pair of slots having wire engaging means for the other incoming wire and also for the other outgoing wire.
Claim 3
Dependent Claim 24 words
The system of claim 1 in which said switch is a part of one block and said receptacle is a part of another block.
Claim 4
Dependent Claim 18 words
The system of claim 2 in which both of said blocks are attached to a common fastening plate.
Claim 5
Dependent Claim 16 words
The system of claim 2 in which said receptacle is attached to its own fastening plate.
Claim 6
Dependent Claim 19 words
The system of claim 1 in which said switch and said receptacle are contained in a single integral block.
Claim 7
Dependent Claim 21 words
The system of claim 5 in which the electrical connections between the switch and the receptacle are imbedded in said block.
Claim 8
Dependent Claim 21 words
The system of claim 1 in which said receptacle includes a fourth slot with electrical contact means to establish a ground.
Claim 9
Dependent Claim 155 words
An electrical circuit comprising a switch having a first and a second contact point and in combination therewith an outlet receptacle having therein three asymmetrically located slots each having an electrical contact means thereat, two of said slots constituting a pair and being positioned to receive a conventional electrical plug, the contact means of the third slot being electrically connected to said first contact point of the switch and said second contact point of the switch being electrically connected to the contact means of one of said pair of slots, said circuit also including a pair of incoming electricity supply wires which are separately connected to the contact means of said pair of slots and additionally including two outgoing electricity delivery wires one of which is connected to said first contact point of the switch and the other of which is connected to the contact means of the other one of said pair of slots.
Claim 10
Dependent Claim 155 words
An electrical circuit comprising a switch having a first and a second contact point and in combination therewith an outlet receptacle having therein three asymmetrically located slots each having an electrical contact means thereat, two of said slots constituting a pair and being positioned to receive a conventional electrical plug, the contact means of the third slot being electrically connected to said first contact point of the switch and said second contact point of the switch being electrically connected to the contact means of one of said pair of slots, said circuit also including a pair of incoming electricity supply wires which are separately connected to the contact means of said pair of slots and additionally including two outgoing electricity delivery wires one of which is connected to said first contact point of the switch and the other of which is connected to the contact means of the other one of said pair of slots.
Claim 11
Dependent Claim 58 words
The circuit of claim 8 which includes a dimmer switch having an enclosing casing, manually variable current controlling means therein having two electrical contact points, and two plug prongs which are inserted respectively in said third slot and in said one of the pair of slots and electric wires separately connecting said contact points to said plug prongs.
Claim 12
Dependent Claim 18 words
The circuit of claim 9 in which said plug prongs are carried by a wall of said casing.
Claim 13
Dependent Claim 29 words
The circuit of claim 9 in which said plug prongs are carried by a separate prong support which is connected through said electric wires to the current controlling means.
Claim 14
Dependent Claim 117 words
The circuit of claim 8 which includes a timer switch having an enclosing casing, an electric clock motor therein and operatively connected thereto a switch to be activated and deactivated thereby at preset times, a pair of plug prongs which are inserted in said pair of slots and a third prong which is inserted in said third slot, said pair of plug prongs being electrically connected to said electric clock to continuously energize it, said third prong being electrically connected to a contact point of said switch, and the other contact point of said switch being electrically connected to that one of said pair of prongs which is inserted in said one of said pair of slots.
Claim 15
Dependent Claim 18 words
The circuit of claim 12 in which said plug prongs are carried by a wall of said casing.
Claim 16
Dependent Claim 28 words
The circuit of claim 12 in which said plug prongs are carried by a separate prong support which is connected through said electric wires to the timer switch.
