Claim 5

A beverage infusion apparatus comprising, in combination, a first container adapted to contain a quantity of a fluid to be heated, and having an opening at its upper end; a cover forming a closure for said opening; a first conduit opening through said cover and extending upwardly from said cover from a filter wall; a second container adapted to be supported on said cover and having an opening to receive said first conduit for supply of fluid to said second container; a tubular member positionable in said first container and engageable between said first container and said cover; said tubular member having an upper portion forming a side wall defining a chamber for the coffee powder, an intermediate shoulder, and a lower cylindrical wall having a lower end edge; and an inner removable member insertable into said tubular member and including a bell positionable within said cylindrical wall to define therewith a riser passage, a filter disk adapted to rest on said shoulder and defining the bottom wall of said powder chamber, and a stem extending upwardly from said filter disk and forming a handle for removing said inner member from said tubular member; said stem, during assembly of the parts, contacting said filtering wall.

Claim 6

A beverage infusion apparatus comprising, in combination, a first container adapted to contain a quantity of a fluid to be heated, and having an opening at its upper end; a cover forming a closure for said opening; a first conduit opening through said cover and extending upwardly from said cover from a filter wall; a second container adapted to be supported on said cover and having an opening to receive said first conduit for supply of fluid to said second container; a tubular member positionable in said first container and engageable between said first container and said cover; said tubular member having an upper portion forming a side wall defining a chamber for the coffee powder, an intermediate shoulder, and a lower cylindrical wall having a lower end edge; and an inner removable member insertable into said tubular member and including a bell positionable within said cylindrical wall to define therewith a riser passage, a filter disk adapted to rest on said shoulder and defining the bottom wall of said powder chamber, and a stem extending upwardly from said filter disk and forming a handle for removing said inner member from said tubular member; said stem, during assembly of the parts, contacting said filtering wall.

Claim 7

A beverage infusion apparatus, as claimed in claim 3, in which said cylindrical wall is relatively elongated; said bell having an elongated cylindrical wall and a closed upper end secured by said stem to said filter disk; the lengths of said cylindrical walls of said tubular member and said bell being such that the lower ends thereof are spaced only a short distance from the bottom of said first container, when the parts are assembled.

Claim 8

A beverage infusion apparatus, as claimed in claim 3, in which said intermediate shoulder is defined by the junction of said chamber-defining side wall and a hopper-shaped portion of said tubular member, said hopper-shaped portion opening into a relatively small diameter tubular conduit continued as a radially outwardly extending and downwardly sloping wall terminated by said cylindrical wall; said bell having a closed upper end secured to said radially outwardly extending and downwardly sloping wall at spaced points to provide a passage therebetween connecting said riser passage to said small diameter tubular conduit.

Claim 9

An assembly designed for use with a coffeepot of the type including a first container adapted to contain a quantity of fluid to be heated, and having an opening at its upper end, a cover forming a closure for the opening, a first conduit opening through the cover and extending upwardly from the cover from a filter wall, and a second container adapted to be supported on the cover and having an opening to receive the first conduit to supply fluid to the second container; said assembly comprising, in combination, a tubular member having an upper lip engageable between said first container and said cover, and having an upper portion forming a side wall defining a chamber for coffee powder, an intermediate shoulder, and a lower cylindrical wall portion having a lower end edge; and an inner removable member including a bell adapted to be positioned within said cylindrical wall to define therewith a riser passage, a filter disk adapted to rest on said shoulder to define the bottom of said powder chamber, and a stem extending upwardly from said filter disk and forming an operational means for removal of said inner member from said tubular member.

Claim 10

An assembly designed for use with a coffeepot of the type including a first container adapted to contain a quantity of fluid to be heated, and having an opening at its upper end, a cover forming a closure for the opening, a first conduit opening through the cover and extending upwardly from the cover from a filter wall, and a second container adapted to be supported on the cover and having an opening to receive the first conduit to supply fluid to the second container; said assembly comprising, in combination, a tubular member having an upper lip engageable between said first container and said cover, and having an upper portion forming a side wall defining a chamber for coffee powder, an intermediate shoulder, and a lower cylindrical wall portion having a lower end edge; and an inner removable member including a bell adapted to be positioned within said cylindrical wall to define therewith a riser passage, a filter disk adapted to rest on said shoulder to define the bottom of said powder chamber, and a stem extending upwardly from said filter disk and forming an operational means for removal of said inner member from said tubular member.
