Abstract
Abstract A rotary receptacle for supplying electric power to a rotating power-using device includes a nonrotating housing separated into two compartments by a rotary insulating disk. Each face of the disk carries a brush which runs against the interior surface of a slip ring housed within the corresponding compartment and shaped and dimensioned so as to provide maximum spacing between each slip ring and the periphery of the insulating disk.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
69 words
An electric receptacle comprising: an annular nonrotating housing; a rotor within the housing comprising a disk dividing the housing into two substantially noncommunicating compartments; a brush on each face of the disk within its individual compartment including integral contactor means for making electrical contact with a rotary device; and a slip ring in each compartment surrounding the corresponding brush and contacted by the same on its radially inward surface.
Claim 2
Dependent Claim
69 words
An electric receptacle comprising: an annular nonrotating housing; a rotor within the housing comprising a disk dividing the housing into two substantially noncommunicating compartments; a brush on each face of the disk within its individual compartment including integral contactor means for making electrical contact with a rotary device; and a slip ring in each compartment surrounding the corresponding brush and contacted by the same on its radially inward surface.
Claim 3
Dependent Claim
69 words
A receptacle as set forth in claim 1 in which each slip ring is formed with an axially extending cylindrical ring portion for contact with its brush which portion is of significantly smaller diameter than said disk, and an outwardly extending radial guide flange for loosely centering the slip ring within the housing, the radial flange being positioned at the side of each slip ring remote from the disk.
Claim 4
Dependent Claim
35 words
A receptacle as set forth in claim 1 in which the housing is provided with exterior projections designed for cooperation with fixed track means to provide for floating non-rotary motion of the housing when required.
Claim 5
Dependent Claim
45 words
A receptacle as set forth in claim 1 which further includes closure disks for the housing and in which the closure disks are attached to opposite ends of the rotor and fit against the faces of the annular housing to close the end openings thereof.
Claim 6
Dependent Claim
57 words
A receptacle as set forth in claim 1 in which each face of the disk is provided with a raised island dimensioned to lie substantially within the corresponding slip ring, which island is provided with a slot, and in which the brush is frictionally held in place on the rotor by its contact with the slot walls.
Claim 7
Dependent Claim
54 words
A receptacle as set forth in claim 5 in which each brush is a portion of a combined integral brush and contactor element, presenting retaining sections for cooperation with the slot and two oppositely directed resilient brush sections for contact with the interior surface of the corresponding slip ring at substantially opposite sides thereof.
Claim 8
Dependent Claim
50 words
A receptacle as set forth in claim 6 in which the rotor is provided with two axial openings for receiving the connector of a rotary device to be electrified, and in which each integral brush and contactor element includes an integral contactor blade extending into one of said axial openings.
Claim 9
Dependent Claim
63 words
A receptacle as set forth in claim 1 in which the slip rings are a relatively loose fit within the housing, the housing includes a radial slot in line with each slip ring position, and each slip ring includes an integral tab for making exterior circuit connections and which lies within one of said slots to prevent rotation of its corresponding slip ring.
Claim 10
Dependent Claim
36 words
A receptacle as set forth in claim 6 in which the slip rings are a relatively loose fit within the housing and are approximately centered by the opposing contact of the two resilient brushes acting thereon.
