Abstract
An insulation blower having hands-free metered feeding. Insulation is stripped from a supply bale and fed into a plurality of chambers of a rotating chamber wheel. The rate at which insulation is fed into the chambers is metered by a feeder assembly which eats through the bale. As the filled chambers sequentially pass through an air lock, the insulation therein is blown out of a lower airlock port and into a delivery tube. Air from a blower is introduced into the airlock through a metered airbox which allows adjustment of the amount of air delivered to the airlock and hence the rate of insulation blown through the delivery tube. Closing off the airbox completely causes air from the blower to enter the delivery tube directly (bypassing the airbox and airlock) in order to clear obstructions in the delivery tube.
