A peristaltic pump assembly and system that facilitates reliable and efficient engagement and removal of a flexible tube. A stator is pivotally retained on a structure and cooperatively operated by a lever arm and cam to engage and disengage the stator from the tube and a corresponding rotor. The stator pivots at a point distal from a point of rotation of the rotor and the lever arm moves about a fixed rotation axis to engage and disengage the stator with the tube relative to the rotor.

An improved single stage snowthrower includes a housing with an open front portion, the housing including two side walls, a rear wall therebetween and a discharge chute. The rear wall includes deflecting ledges that angle upwardly toward the discharge chute, inwardly toward the center of the housing and forwardly toward the open front. The deflecting ledges provide both an inward and an upward component to snow travelling in the housing. The snowthrower also includes an impeller having axial ends and a radial edge. The impeller is comprised of two molded identical body sections that are joined about a shaft. Each body section includes a central portion, two end portions and a pair of helical portions with one helical portion between each end portion and the central portion. A portion of the radial edge of the impeller includes a shovel-like projection that is oriented in a direction extending laterally away from the impeller in the direction of rotation of the impeller.

Two-piece impeller

A readily disassemblable cabinet for a liquid dispensing system includes a supporting frame assembly having a base plate and a shelf, and further includes readily removable front, rear, and side panels and a separately removable top support and top panel. Readily removable metal rods are provided to secure individual base, shelf and top support components to the frame assembly. Such rods permit the quick removal of the system components and thus facilitate routine maintenance of the liquid dispensing system while minimizing the number of tools required to service the unit. The upper surface of the shelf supports a readily removable reservoir and the underside of the shelf is formed with brackets for receiving cross pins which removably support a hot tank for pivotal and translational movement toward and away from a valved waterway suspended below the reservoir.
