<p>A combined air/electrical swivel is described which includes interfitting and relatively rotatable swivel bodies which are locked together by a ball bearing assembly. The swivel is stabilized by means of a thrust bearing axially spaced from the ball bearing assembly. Electrical connection between the relatively rotatable swivel bodies is accomplished by means of slip rings on the one body which are contacted by brushes in the form of springs with split ends.</p> |
