Abstract
Abstract A rotatable platform is provided with a centrally disposed stanchion and a number of electrical kitchen appliances are grouped about the stanchion in a circular array. The platform is rotatably supported from a base about the axis of the stanchion and electrical connection to the appliances may be completed by pushing them inwardly toward the stanchion. An electrical outlet plug and cord extends to the base and a pair of electrical conductor rings and brushes complete the connection between the base and the platform so that the platform may be rotated to any desired position without interrupting the electrical circuit.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
139 words
A lazy susan type of electrical kitchen appliance whereby any one of a number of individual electrical appliances may be brought to a desired position, comprising in combination: a platform having a centrally disposed, upstanding stanchion and a circular array of electrical appliances grouped around said stanchion, each of said appliances having a pair of electrical connectors and said stanchion having openings for receiving said connectors whereby said appliances may be pushed inwardly toward said stanchion to obtain electrical energization thereof; contact means within said stanchion for electrical connection respectively with each of said pair of electrical connectors of the appliances; a base rotatably supporting said platform about the axis of said stanchion; and, means coacting between said base and said platform for electrically energizing said contact means irrespective of the rotational position of said platform on said base.
Claim 2
Dependent Claim
139 words
A lazy susan type of electrical kitchen appliance whereby any one of a number of individual electrical appliances may be brought to a desired position, comprising in combination: a platform having a centrally disposed, upstanding stanchion and a circular array of electrical appliances grouped around said stanchion, each of said appliances having a pair of electrical connectors and said stanchion having openings for receiving said connectors whereby said appliances may be pushed inwardly toward said stanchion to obtain electrical energization thereof; contact means within said stanchion for electrical connection respectively with each of said pair of electrical connectors of the appliances; a base rotatably supporting said platform about the axis of said stanchion; and, means coacting between said base and said platform for electrically energizing said contact means irrespective of the rotational position of said platform on said base.
Claim 3
Dependent Claim
38 words
The lazy susan assembly as defined in claim 1 wherein said stanchion is in the form of a hollow cylinder and said contact means comprises a pair of vertically spaced annular contact bars snugly received in said stanchion.
Claim 4
Dependent Claim
38 words

Claim 8
Dependent Claim
134 words
A lazy susan electrical kitchen appliance assembly comprising, in combination: a base and a platform surmounting said base; means for guiding and supporting said platform on said base for rotation about a vertical axis; a stanchion fixed to said platform and upstanding therefrom in alignment with said axis of rotation, said stanchion having a plurality of pairs of electrical connection ports disposed in horizontally spaced relation therearound; a plurality of sector-shaped electrical applicances supported on said platform, each having a pair of electrical connectors projecting horizontally therefrom in alignment with a pair of said ports; separate electrical contact means within said stanchion at each pair of said ports; and means coacting between said base and said platform for electrically energizing said conductor means irrespective of the rotational position of said platform on said base.
Claim 9
Dependent Claim
134 words
A lazy susan electrical kitchen appliance assembly comprising, in combination: a base and a platform surmounting said base; means for guiding and supporting said platform on said base for rotation about a vertical axis; a stanchion fixed to said platform and upstanding therefrom in alignment with said axis of rotation, said stanchion having a plurality of pairs of electrical connection ports disposed in horizontally spaced relation therearound; a plurality of sector-shaped electrical applicances supported on said platform, each having a pair of electrical connectors projecting horizontally therefrom in alignment with a pair of said ports; separate electrical contact means within said stanchion at each pair of said ports; and means coacting between said base and said platform for electrically energizing said conductor means irrespective of the rotational position of said platform on said base.
Claim 10
Dependent Claim
