Stirrer devices for culinary purposes

Claim 2

A cooking vessel comprising: a body which includes a base portion having an upper surface which is a surface of revolution about a substantially vertical axis of revolution; a lid for said body; a shaft; means journalling said shaft in said lid for rotation about said axis of revolution of said surface of revolution; drive means connected to said shaft for causing rotation thereof; a plurality of wiper arms; and a plurality of resilient connections each attaching a respective one of said wiper arms to the lower end of said shaft so as to bias said wiper arms into wiping contact with said upper surface of said base portion, said arms extending outwardly from said axis and being so positioned as to wipe the major part of said upper surface as said shaft is rotated.

Claim 3

A cooking vessel according to claim 1 wherein said upper surface of said base portion is circular and a pair of wiper arms extended radially outwardly from said shaft in respective opposite directions and are joined together at their inner ends, each said resilient connection being a curved member extending generally radially outwardly from said shaft and then doubling back on itself before meeting the associated arm.

Claim 4

A hand-portable cooking vessel comprising a body having a flat base portion; said base portion having a flat upper surface; a lid for said body; a shaft; means journalling said shaft in said lid for rotation about a vertical axis located substantially centrally of the center of said upper surface of said base portion; an electric motor; means coupling said electric motor to said shaft for causing rotation of said shaft; at least one battery connected to power said motor; a plurality of wiper arms; and a plurality of resilient connections each attaching a respective one of said wiper arms to the lower end of said shaft so as to bias said wiper arms into wiping contact with said upper surface of said base portion, said arms extending outwardly from said axis and being so positioned as to wipe the major part of said upper surface as said shaft is rotated.

Claim 5

A hand-portable cooking vessel comprising a body having a flat base portion; said base portion having a flat upper surface; a lid for said body; a shaft; means journalling said shaft in said lid for rotation about a vertical axis located substantially centrally of the center of said upper surface of said base portion; an electric motor; means coupling said electric motor to said shaft for causing rotation of said shaft; at least one battery connected to power said motor; a plurality of wiper arms; and a plurality of resilient connections each attaching a respective one of said wiper arms to the lower end of said shaft so as to bias said wiper arms into wiping contact with said upper surface of said base portion, said arms extending outwardly from said axis and being so positioned as to wipe the major part of said upper surface as said shaft is rotated.

Claim 6

A hand-portable cooking vessel according to claim 3 wherein a pair of wiper arms extend radially outwardly from said axis in respective opposite directions and are joined together at their inner ends, each said resilient connection being a curved member extending generally radially outwardly from said shaft and then doubling back on itself before meeting the associated arm.

Claim 7

A cooking vessel lid having a shaft journalled for rotation therein and extending substantially vertically downwardly therefrom; drive means connected to said shaft for causing rotation thereof; a plurality of wiper arms; and a plurality of resilient connections each attaching a respective one of said wiper arms to the lower end of said shaft so that said arms extend outwardly of the axis of said shaft and are biassed downwardly.

Claim 8

A cooking vessel lid having a shaft journalled for rotation therein and extending substantially vertically downwardly therefrom; drive means connected to said shaft for causing rotation thereof; a plurality of wiper arms; and a plurality of resilient connections each attaching a respective one of said wiper arms to the lower end of said shaft so that said arms extend outwardly of the axis of said shaft and are biassed downwardly.

Claim 9

A cooking vessel lid according to claim 5 wherein a pair of wiper arms extend radially outwardly from said shaft in respective opposite directions and are joined together at their inner ends, each said resilient connection being a curved member extending generally radially outwardly from said shaft and then doubling back on itself before meeting the associated arm.
