Patent ID: 7360719

Claim:
An insulation gun for in combination with a loose fill insulation supply apparatus including, a blower, a first clutch controlled by a first control circuit for engaging or disengaging a motor with said blower, an air box in communication with said blower, an insulation feed device for transferring said loose fill insulation to said air box, a second clutch controlled by a second control circuit for engaging or disengaging said motor with said insulation feed device and an insulation hose having a proximate end in communication with said air box and opposite distal end, said insulation hose for carrying said loose fill insulation material in an air stream away from said air box, said insulation gun comprising: (a) a hollow barrel for communication with said distal end of said insulation hose, (b) a first switch connected in said first clutch control circuit and also connected in said second clutch control circuit, said first switch operating between an open position in which said first and second clutch control circuits are open thus causing disengagement of said first and second clutches such that power is not provided in said blower and said insulation feed device and a closed position in which said first and second clutch control circuits are closed thus causing engagement of said first and second clutches such that power is provided to said blower and said insulation feed device, (c) a second switch connected in said second control circuit said second switch operating between an open position in which said second clutch control circuit is open thus causing disengagement of said second clutch such that power is not provided to said insulation feed device and a closed position in which said second clutch control circuit is closed causing engagement of said second clutch such that power is provided to said insulation feed device if said first switch is also closed, whereby an operator using said insulation gun activates said insulation feed device and said blower and thus causes loose fill insulation to flow into an insulation space by closing said first switch and said second switch and whereby an operator deactivates said insulation feed device while continuing to activate said blower by closing said first switch and opening said second switch or whereby an operator deactivates said insulation feed device and said blower by opening said first switch.
