Many of the old blowers had spring load primary blower wheels. When they clogged with slush and such, they would stall with the springs on the shaft well compressed....when someone put their hand in and cleared the blockage, they would let go and the primary blower wheel would spin part of a turn...but that was enough to take some fingers off.
