The ornamental design for a coffeemaker, as shown and described.
FIG. 1 is a perspective view of a coffeemaker embodying our new design;
FIG. 2 is a top plan view thereof;
FIG. 3 is a side elevational view thereof, the opposite side view being
substantially a mirror image thereof;
No front elevational, rear elevational or bottom plan views are shown
inasmuch as the front of the coffeemaker is fully shown in the perspective
view of FIG. 1 and the back and bottom of the coffeemaker are plain and
unornamented.
