Abstract
Abstract A device from which articles can be suspended comprising a suspension post, a first rotor, a first bearing having a shaft and a race rotatable about the shaft, the first end of said shaft of said first bearing being rigidly mounted with respect to said suspension post, said rotor being carried by said race of said first bearing for rotation about the axis of the shaft of said first bearing, a first bearing coupler rigidly mounted with respect to said shaft of said first bearing and adapted to receive in rigid coupling relation one end of the shaft of a second bearing that is similar to said first bearing, an article support arm assembly carried by said rotor.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
120 words
A device from which articles can be suspended comprising: a suspension post; a first rotor; a first bearing having a shaft with two ends and a race rotatable about the shaft; one end of said shaft of said first bearing being rigidly mounted with respect to said suspension post; said rotor being carried by said race of said first bearing for rotation about the axis of the shaft of said first bearing; a first bearing coupler rigidly mounted with respect to said shaft of said first bearing and adapted to receive in rigid coupling relation one end of the shaft of a second bearing that is similar to said first bearing; an article support arm assembly carried by said rotor.
Claim 2
Independent Claim
120 words
A device from which articles can be suspended comprising: a suspension post; a first rotor; a first bearing having a shaft with two ends and a race rotatable about the shaft; one end of said shaft of said first bearing being rigidly mounted with respect to said suspension post; said rotor being carried by said race of said first bearing for rotation about the axis of the shaft of said first bearing; a first bearing coupler rigidly mounted with respect to said shaft of said first bearing and adapted to receive in rigid coupling relation one end of the shaft of a second bearing that is similar to said first bearing; an article support arm assembly carried by said rotor.
Claim 3
Dependent Claim
33 words
A device from which articles can be suspended as claimed in claim 1 having braking means for adjustably braking the rotation of said rotor with respect to said shaft of said first bearing.
Claim 4
Dependent Claim
51 words
A device from which articles can be suspended as claimed in claim 1 having stop means rigid with respect to said shaft of said bearing and cooperating stop means rigid with respect to said rotor for limiting the arc of rotation of said rotors about said shaft of said first bearing.
Claim 5
Dependent Claim
51 words
A device from which articles can be suspended as claimed in claim 2 having stop means rigid with respect to said shaft of said bearing and cooperating stop means rigid with respect to said rotor for limiting the arc of rotation of said rotors about said shaft of said first bearing.
Claim 6
Dependent Claim
30 words
A device from which articles can be suspended as claimed in claim 1 wherein said stop means that are rigid with respect to said shaft are carried by said coupler.
Claim 7
Dependent Claim
30 words
A device from which articles can be suspended as claimed in claim 2 wherein said stop means that are rigid with respect to said shaft are carried by said coupler.
Claim 8
Dependent Claim
29 words
A device from which articles can be suspended as claimed in claim 1 in which said coupler comprises a collar that extends around the shaft of said bearing assembly.
Claim 9
Dependent Claim
29 words
A device from which articles can be suspended as claimed in claim 2 in which said coupler comprises a collar that extends around the shaft of said bearing assembly.
Claim 10
Dependent Claim
60 words
A device from which articles can be suspended as claimed in claim 2 in which said braking means comprises a braking collar threadedly mounted for rotation with respect to said shaft of said first bearing for movement longitudinally of said shaft of said first bearing, a brake shoe and brake spring assembly operative between said braking collar and said rotor.
Claim 11
Dependent Claim
97 words
A device from which articles can be suspended as claimed in claim 2 in which said braking means comprises a braking collar threadedly mounted for rotation with respect to said shaft of said first bearing for movement longitudinally of said shaft of said first bearing, a brake shoe and brake spring assembly operative between said braking collar and said rotor, stop means rigid with respect to said shaft of said bearing and cooperating stop means rigid with respect to said rotor for limiting the arc of rotation of said rotors about said shaft of said first bearing.
Claim 12
Dependent Claim
93 words
A device from which articles can be suspended as claimed in claim 1 having a second bearing rigidly coupled to said first bearing coupler, a second rotor similar to said first rotor carried by the race of said second bearing for rotation about the axis of the shaft of said second bearing assembly, a second bearing coupler rigidly mounted with respect to the shaft of said second bearing and adapted to receive in rigid coupling relation one end of a third bearing that is similar to said first bearing and said second bearing.
