Surface abrading machine

Abstract

An apparatus for abrading surfaces has a first manifold mounted proximate one end of a shaft, and a second manifold mounted distal to one end of the shaft, said first and second manifolds being constructed to receive and distribute a fluid under positive pressure and vacuum pressure, the shaft being connected to the first and second manifolds to support the manifolds and the shaft includes fluid pathways to conduct air and vacuum flows of the fluid between the manifolds, and an end effector for treating surfaces.

I claim: 
     
         1 . Apparatus for abrading surfaces comprising a first manifold mounted proximate one end of a shaft, and a second manifold mounted distal to said one end of the shaft, wherein said first and second manifolds receive and distribute a fluid under positive pressure and vacuum pressure, and said shaft is connected to said first and second manifolds and includes fluid pathways to conduct air and vacuum flows of said fluid between said manifolds, and an end effector for treating surfaces. 
     
     
         2 . Apparatus according to  claim 1  wherein said first manifold comprises a connector for receiving a fluid under pressure, an outlet for providing said fluid to said end effector, and at least one outlet for providing said fluid to one or more power control switches. 
     
     
         3 . Apparatus according to  claim 2  wherein said first manifold comprises a power control lever that adjusts the fluid directed to said end effector. 
     
     
         4 . Apparatus according to  claim 2  further comprising a fluid operated conveyor and said first manifold includes an outlet for providing said fluid to an inlet of said fluid operated conveyor. 
     
     
         5 . Apparatus according to  claim 4  wherein said second manifold includes an inlet for receiving said fluid from said first manifold and distributing said fluid to an outlet for supplying said fluid to said end effector. 
     
     
         6 . Apparatus according to  claim 4  wherein said fluid operated conveyor is mounted to said second manifold. 
     
     
         7 . Apparatus wherein said shaft is extruded aluminum.
