this character, water is placed within the lower
bowl and is heated. The pressure of the water
vapor and air above the water level forces the
water up through the tube into the upper bowl
where the coffee is steeped or infused. When the
heat is removed from the lower bowl, the water ~
vapor in the lower bowl condenses and the pres
sure is thereby reduced sufficiently to cause the
coffee infusion in the upper bowl to return
through the ?lter to the lower bowl. After this,
the upper bowl is removed and the infusion may

This invention has as- one of its objects the
provision of an improved handle‘ construction for

manipulated to pour the coffee brew from the
In accordance with this invention, in one form
thereof, the handle construction comprises a pair

ranged to embrace opposite sides of the neck of
the lower bowl that‘ receives the tubular mem
ber attached to the upper bowl. These mem
bers are provided with arms extending from the

preferably formed of rubber, is inserted in the
neck l2 of the lower bowl and is provided with a
centrally arranged aperture to receive the ex 15
tension l3 provided on the upper bowl H.
The extension l3 merges into a downwardly
tapered tubular member l5, which co-operates
with the extension l3 to provide a funnel con
nection between the lower bowl l0 and the upper 20
bowl ll. Preferably and'as shown, the extension
l3 and the tapered tube l5 will be formedinte
grally with the upper bowl H, and preferably
these members will be formed of glass. It is also
‘preferable to form the lowerbowl l I] of glass.
