Abstract
An impeller and shield for a mixing apparatus. A mixing member has upper and lower opposite faces and one or more apertures therethrough. Each of the apertures has an upper periphery defined by an edge of the lower face and a lower periphery defined by an edge of the upper face. The mixing member is preferably an otherwise substantially planar disc having a hole through the center for receiving a motor driven shaft.
Claims10
An impeller for a mixing apparatus, comprising a mixing member having upper and lower opposite faces and one or more apertures therethrough, each of said apertures having an upper periphery defining an edge of said lower face and a lower periphery defining an edge of said upper face, wherein said mixing member is an otherwise substantially planar disc having a hole through the center for receiving a motor driven shaft.
A shield for a mixing apparatus having a shaft with a predetermined diameter, comprising a substantially planar shield member having spaced apart upper and lower opposite surfaces and an elongate aperture therethrough, said shield member having an open end at the periphery thereof for receiving the shaft into and through said aperture, said slot having a width dimension that is larger than the diameter of the shaft, and a dust flap member disposed over said aperture so as to avoid interfering with the shaft when the shaft extends through said aperture, said dust flap member having a plug portion adapted to fit into said aperture and thereby to reduce the amount of open space therein.
