System and apparatus for electrically connecting a vacuum cleaner and a remote motor driven brush tool

Claim 1

The combination comprising a fluid-conducting hose, including a carcass, an end fitting at least at one end of said hose, a ring of uncured rubber on said hose adjacent said one end, first means comprising a pair of split sleeve members for radially compressing said ring on said hose, each said split sleeve having a semiannual recess for receiving and confining said ring, at least one bearing sleeve member overlying said split sleeves and holding said split sleeves against radial separation, second means for connecting said fitting with said first means, conductor means integral with said carcass, said pair of split sleeve members having an axial extension remote from said semiannular recess, a pair of axially spaced slip rings on said axial extension connected with said conductor means, a second bearing sleeve member on said axial extension, said end fitting comprising a handle member having an open barrel portion for receiving said split sleeve members and assembled slip rings and bearing sleeve members, said barrel portion having openings aligned with said slip rings, harness means having a pair of brushes extending through said openings for engaging said slip rings, said harness means including a plug connected to said handle adjacent one end thereof, a telescoping wand connectable to said end fitting, said wand having an outer tubular wand section and an inner tubular wand section, said inner section being adapted to slide within said outer section, channel means connected with said outer wand section, a pair of spaced parallel elongated conductor strips within said channel means, rigid conductor means connected with said inner wand section and slidable within said channel, sliding contact means connected with rigid conductor means for engaging said elongated conductor strips, a suction tool having a motor driven brush means and a pivotal elbow adapted to connectively receive said inner tubular wand section, a plug member connected with said elbow adjacent one end of said elbow for electrically connecting said plug with said rigid conductor means, a pair of conductors connected to said plug at one end, each conductor having a brush at the other end, and a pair of spaced collector cups connected with the motor of said motor driven brush means and disposed coaxially with the pivotal axis of said elbow, each brush movably engaging one of said collector cups for electrically coupling said motor and said elbow plug.
