Abstract: A belt grinding finishing tool incorporates a pair of mounting arms projecting forwardly from a drive housing to support a single abrasive belt entrained around drive and idler pulleys. The first mounting arm is positionally fixed relative to the drive housing, but the second mounting arm is pivotally mounted to permit relative pivotal movement thereof. The dual mounting arm configuration enables a tubular member to be placed between the mounting arms to effect a finishing of opposing sides of the outer surface of the tubular member simultaneously. A support housing detachably mounted on the drive housing includes a support handle that can be selectively connected to alternative attachments mounts formed on the support housing. An actuation lever extending outwardly from the second mounting arm permits the operator to cause pivotal movement of the pivoted second mounting arm to accept the tubular member to be finished between the mounting arms.

Abstract: An automatically draining vacuum apparatus for collecting a fluid to be vacuumed. The vacuum apparatus includes a vacuum generating source which generates a suction force and a tank for holding the fluid to be vacuumed. The tank includes a vacuum port, an inlet and a drainage opening for emptying fluid held within the tank. The suction force at the vacuum port draws the fluid to be vacuumed into the tank through the inlet and prevents the fluid within the tank from passing from the tank through the drainage opening. A float is located in the tank for closing off the vacuum port to prevent the fluid within the tank from passing through the vacuum port. The float has a positive buoyancy with respect to the fluid and is positioned within the tank such that when the fluid within the tank is above a predetermined level, the suction force at the vacuum port and the float buoyancy maintain the float in a blocking position to at least partially block the vacuum port, creating a second suction force.
