## Abstract

A coffeepot is provided having a whistle and pouring opening located in a skirt depending from the lid. The lid is rotatable within the pot to bring the whistle and pouring opening into communication with a pouring spout, or so that they are blocked by the pot sidewall. A basket having upper and lower steel filters of fine mesh is supported spaced from, but adjacent, the coffeepot bottom for ensuring immersion of the coffee within the water during the brewing cycle.

## Claims

### Claim 1

A coffeemaker comprising:
a pot having a closed bottom, a circumferentially continuous side wall, and an open top, and a handle extending from the side wall;
a pouring spout extending from a portion of the exterior side wall opposite the handle;
a basket mounted in the pot for containing coffee, and having lift-out means extending upwardly therefrom toward the open top;
a lid for closing the open top and including a handle portion located centrally on top of the lid; said lid having a depending skirt portion with a smaller outside diameter than the inside diameter of the pot, and overlapping the pouring spout;
means defining a pair of openings in the depending skirt; and
whistle means associated with one of said skirt openings, while the other opening remains free.

### Claim 2 (depends on 1)

A coffeemaker as recited in claim 1 wherein said openings in said skirt are mounted so that both may be in communication with said pouring spout at the same time.

### Claim 3 (depends on 2)

A coffeemaker as recited in claim 2 wherein said openings are at approximately the same vertical position but are circumferentially and horizontally spaced from each other.

### Claim 4 (depends on 2)

A coffeemaker as recited in claim 2 and wherein said handle on top of said lid is of a non-heat conducting material; wherein said skirt is seated for rotation within said pot, so that said lid may be rotated from a position wherein both said whistle means on said pouring openings of said skirt communicate with said pouring spout to a position wherein neither said whistle means nor said pouring opening communicate with said pouring spout.

### Claim 5 (depends on 4)

A coffeemaker as recited in claim 4 wherein said skirt depends downwardly from said lid so that after inserting said lid into the open top of said pot, said skirt fits snugly against said sidewall, said skirt ending at a point lower than said pouring spout relative to the bottom of said pot.

### Claim 6 (depends on 5)

A coffeemaker as recited in claim 5 wherein said skirt and said pot have indicia for aligning said pouring opening and said whistle with said pouring spout.

### Claim 7 (depends on 6)

A coffeemaker as recited in claim 6 wherein said pouring spout further comprises means for preventing the coffee being removed from said pot from collecting in the bottom of said pouring spout.

### Claim 8 (depends on 2)

A coffeemaker as recited in claim 2 wherein said basket further comprises filter means on the top and bottom, circumferentially continuous side walls, a cross-sectional diameter less than a similar diameter across said coffeepot, and having a lift-out member attached to the top filter.

### Claim 9 (depends on 8)

A coffeemaker as recited in claim 8 wherein said basket rests upon a plurality of support members extending upwardly from the bottom of said pot so that said basket never directly contacts the bottom of said pot and thereby remaining totally immersed in water during operation.

### Claim 10 (depends on 1)

A coffeemaker as recited in claim 1 wherein said lift-out means further comprises a hollow tube located centrally on top of said basket, communicating with interior of said basket, and then extending upwardly from said basket towards the open top of said pot.

### Claim 11 (depends on 1)

A coffeemaker as recited in claim 1 wherein said lift-out means further comprises a flat solid bar with one portion attached to the top of said basket, said bar having a second end with non-heat conducting material located rear of the open end of said pot.
