Liquid mixing and dispensing device

Claim 2

A liquid mixing and dispensing device comprising: a. an open-topped, generally cylindrical container; b. a closure member for the open top of said container; c. a tubular housing mounted in said closure member and extending axially of said container for rotary and axial movement relative to said container and closure member; d. a shaft coaxial with said tubular housing and mounted therein for axial movements therewith and for rotation relative to said housing and container, said shaft having opposite upper and lower ends; e. a disk-like impeller mounted fast on the lower end of said shaft below said housing; f. handle means on the upper end of said shaft above said housing and closure member; g. and cooperating stop elements on said closure member and said tubular housing for limiting upward movement of said impeller, shaft and housing, relative to said container and closure member, between the bottom of said container and a plurality of predetermined levels above said bottom of the container.

Claim 3

The liquid mixing and dispensing device defined in claim 1 in which said stop means comprises a plurality of axially spaced abutment elements on said housing and a cooperating stop element on said closure member, said abutment elements being movable selectively into alignment with said stop element.

Claim 4

The liquid mixing and dispensing device defined in claim 2 in which said tubular housing defines a plurality of circumferentially spaced grooves extending axially downwardly from the upper end of said tubular housing, said grooves being of different axial length, the lower ends of said grooves defining said abutment elements.

Claim 5

The liquid mixing and dispensing device defined in claim 3 in which said housing includes ratchet teeth defining said grooves, said stop element comprising a pawl in said closure member yieldingly urged toward engagement with said ratchet teeth.

Claim 6

The liquid mixing and dispensing device defined in claim 1 in which said impeller comprises a disk portion disposed in a plane transversely of the axis of said shaft and housing and having a plurality of openings therethrough for passage of liquids and a plurality of generally radial agitator vanes projecting upwardly from said disk portion.

Claim 7

The liquid mixing and dispensing device defined in claim 1 in further combination with a perforate retainer plate, and support means for holding said retainer plate on said tubular housing in axially spaced relation to said impeller.

Claim 8

The liquid mixing and dispensing device defined in claim 6 in which said retainer plate comprises a pair of segmental sections cooperating to define a central opening, and means for releasably securing said sections together, said support means comprising support pins and pin receiving openings in respective ones of said retainer plate and tubular housing.

Claim 9

The liquid mixing and dispensing device defined in claim 1, characterized by generally flat buoyant plate means having a circular outline, said plate means further having an axial opening therethrough for loosely receiving said tubular housing.

Claim 10

The liquid mixing and dispensing device as defined in claim 8 in which said plate means includes a marginal sealing flange of flexible material projecting radially outwardly therefrom for sliding engagement with the inner cylindrical surface of said container, and a second sealing flange in axial opening for engagement with said tubular housing.

Claim 11

A liquid mixing and dispensing device comprising: a. an open topped generally cylindrical container of translucent material having vertically spaced liquid level indicator marks thereon; b. a closure member for the open top of said container, said closure member having an axial opening therethrough and circumferentially spaced liquid level indicator marks radially outwardly of said opening and corresponding to said marks on said container; c. a tubular housing extending axially within said container and journaled in said closure member for rotary and axial sliding movements relative to said closure member; d. said tubular housing having a radially projecting indicator pointer upwardly of said closure member for imparting rotary movement to said housing; e. a shaft coaxial with said tubular housing and mounted therein for axial movements therewith and for rotation relative to said housing and container, said shaft having opposite upper and lower ends; f. a disk-like impeller mounted fast on the lower end of said shaft below said housing; g. handle means on the upper end of said shaft above said housing and closure member; h. a stop element in said axial opening of the closure member; i. and a plurality of axially and circumferentially spaced abutment elements on said tubular housing selectively axially aligned with said stop element responsive to rotation of said housing, each of said abutment elements engaging said stop element responsive to upward movement of said housing and impeller to limit upward movement thereof to the level of a different one of said level indicator markings on said container.

Claim 12

A liquid mixing and dispensing device comprising: a. an open topped generally cylindrical container of translucent material having vertically spaced liquid level indicator marks thereon; b. a closure member for the open top of said container, said closure member having an axial opening therethrough and circumferentially spaced liquid level indicator marks radially outwardly of said opening and corresponding to said marks on said container; c. a tubular housing extending axially within said container and journaled in said closure member for rotary and axial sliding movements relative to said closure member; d. said tubular housing having a radially projecting indicator pointer upwardly of said closure member for imparting rotary movement to said housing; e. a shaft coaxial with said tubular housing and mounted therein for axial movements therewith and for rotation relative to said housing and container, said shaft having opposite upper and lower ends; f. a disk-like impeller mounted fast on the lower end of said shaft below said housing; g. handle means on the upper end of said shaft above said housing and closure member; h. a stop element in said axial opening of the closure member; i. and a plurality of axially and circumferentially spaced abutment elements on said tubular housing selectively axially aligned with said stop element responsive to rotation of said housing, each of said abutment elements engaging said stop element responsive to upward movement of said housing and impeller to limit upward movement thereof to the level of a different one of said level indicator markings on said container.
