Abstract: An apparatus for grouping packages, composed of a horizontal delivery device for conveying individual packages in sequence, and a vertical conveyor device disposed for receiving the individual packages from the horizontal delivery device, conveying the individual packages vertically and arranging the individual packages in groups for transfer to a horizontal output device. The vertical conveyor device is composed of two parallel-extending endless belts and a plurality of parallel rows of brushes carried by each belt and disposed for engaging each individual package received by the vertical conveyor device from below and supporting each individual package as it is being conveyed vertically.

Abstract: A centrifugal snow blower having a frame, a fan rotatable about a central axis supported on the frame and a housing surrounding said fan having a peripheral wall defining at least an opening in direction of clearing and a duct extending tangentially for the ejection of snow. The housing is supported for rotative adjustment about the central axis by a central bearing journaling the housing to said frame, an annular guide member secured to the housing concentric with the central axis and at least one releasable braking device supported on the frame for cooperation with the guide member to fix said housing in selective rotative positions.
