  • Patent number: 5488949
    Abstract: A dual suction device includes an enclosed housing with a hollow interior cavity and an exhaust port formed in a rearward wall of the housing. A suction tube is pivotally mounted to the housing to pivot between a first position communicating with the exhaust port, and a second position sealed from the exhaust port. A tubular arm is also connected to the housing and fluidly connected to the interior cavity. A flap on the suction tube is moved in conjunction with pivotal motion of the suction tube to selectively alternate suction from the exhaust port between the tubular arm, when the suction tube is in the second position, and the suction tube, when the suction tube is in the first position.
