Abstract
A device for stirring a liquid having two cup-shaped elements coaxially mounted on the end of a shaft. Radial vanes extend between the two elements to define liquid flow passages, the liquid entering from a hole at the apex of the outer cup. The outlet end of each of the vanes is bent at approximately a right angle to the rest of the vane.
Claims3
A device for stirring a liquid, comprising an outer cup-shaped body having inner and outer surfaces of revolution about an axis, an apex and a base end opposite to the apex, and having an opening therethrough at said apex for the passage of liquid to be stirred;
- an inner cup-shaped body having an outer surface of revolution, an apex and a base end, disposed coaxially within said outer body;
- a plurality of blades extending radially between and connected to the outer surface of the inner cup and the inner surface of the outer cup, a first portion of each blade adjoining the base ends of said cups extending at a first angle with respect to a plane perpendicular to said axis, a second portion of each blade closer to said apices extending at a secoond angle from said plane greater than said first angle;
- and a driving shaft connected coaxially to said inner body at a location.
