Blender base

FIG. 1 is a top, front and left side perspective view of a blender base showing my new design;

FIG. 2 is a front elevational view thereof;

FIG. 3 is a rear elevational view thereof;

FIG. 4 is a right side elevational view thereof, with the left side being a mirror image of the right side;

FIG. 5 is a top, front, and right side perspective view of a second embodiment thereof, the only difference residing in the switch mechanism which has a smaller switch plate and which knob rests on the right side of the switch plate; and,

The broken lines showing the jar-supporting tower in FIGS. 1 through 5 and showing the vents on the bottom of the base in FIGS. 3, 4, and 6 are for illustrative purposes only and form no part of the claimed design.
