ABSTRACT:
A stem in an alarm housing coaxially removably coupled to the lid of a coffee pot via a hole formed through the lid extends through the bore of a collar mounted in the housing and having a coaxial bore formed therethrough. A spherical member is coaxially affixed to the stem at an intermediate point thereof and has a diameter greater than the diameter of the bore of the collar and rests in such bore whereby the stem is freely rockable in the collar. A hollow shell is mounted on the stem at the upper end thereof and has a rattle member encased therein which produces an alarm sound whenever it strikes the shell. An actuating member is mounted on the stem at the lower end thereof and is positioned in close proximity with the top of the perforated tube of the coffee pot. Thus, when the coffee perks, water flows into the top of the tube of the coffee pot and strikes the actuating member to produce an oscillatory motion of the stem about the spherical member thereof. This causes the rattle member to strike the shell to produce a series of alarm sounds.
