Abstract
A compact, lightweight snow thrower having a power driven impeller rotating about a horizontal, transverse axis to throw snow upwardly and forwrdly through a chute which is substantially coextensive in width with the axial length of the impeller. A plurality of laterally spaced upright vanes are disposed in and pivotally connected to the upper end of the chute for the purpose of directing the discharge of snow. The vanes are pivotally connected to a control bar whereby movement of the control bar effects simultaneous lateral tilting of the vanes. The vanes include a centrally positioned set which are parallel to one another and a pair of vanes at each of the laterally opposite sidewalls of the chute which are disposed at upwardly converging angles to one another so as to compress the column of discharged snow. One of the sidewalls of the discharge chute is also inclined laterally inwardly in an upward direction. The two laterally opposite, outermost vanes cause a converging effect on the snow being discharged to avoid wide dispersion of the discharged snow.
