Abstract
Abstract A combiner mixer and dispenser apparatus has a pair of co-axial, telescopically mounted tubes having adjacent apertured axial ends adapted to be immersed in a liquid, the outer tube having radial openings selectively closable by the inner tube depending on its axial position relative to the outer tube. A spring urges the inner tube towards a terminal position at which the radial openings are uncovered so that the rotation of an impeller carried by a shaft mounted in the inner tube is effective to draw liquid through an opening in the axial end of the outer tube and expel it through the radial openings thus mixing the liquid. When the inner tube is moved axially to partially or fully cover the radial openings, the liquid drawn through the opening in the end of the outer tube is pumped upwardly through the inner tube and dispensed. A combined mixing and dispensing operation can be carried out simultaneously by positioning the inner tube so that the radial openings in the outer tube are only partially covered.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
167 words
A combined mixer and dispenser apparatus for liquids comprising: a a pair of coaxial, telescopically mounted tubes having adjacent axial ends adapted to be immersed in a liquid; b the axial end of the outer tube being open and having radial openings adjacent thereto, the axial end of the inner tube having an eccentrically located aperture and adapted to selectively close the radial openings in the outer tube depending on the relative axial positions of the tubes; c spring means urging the inner tube towards a terminal axial position relative to the outer tube and establishing the normal position of the inner tube; d an axially fixed rotatable shaft coaxial with the tubes extending centrally through the adjacent axial ends of the tubes and terminating in an impeller; and e means for moving the inner tube reLative to the outer tube against the action of the spring means for establishing the degree to which the radial openings in the outer tubes are covered by the inner tube.
Claim 2
Dependent Claim
167 words
A combined mixer and dispenser apparatus for liquids comprising: a a pair of coaxial, telescopically mounted tubes having adjacent axial ends adapted to be immersed in a liquid; b the axial end of the outer tube being open and having radial openings adjacent thereto, the axial end of the inner tube having an eccentrically located aperture and adapted to selectively close the radial openings in the outer tube depending on the relative axial positions of the tubes; c spring means urging the inner tube towards a terminal axial position relative to the outer tube and establishing the normal position of the inner tube; d an axially fixed rotatable shaft coaxial with the tubes extending centrally through the adjacent axial ends of the tubes and terminating in an impeller; and e means for moving the inner tube reLative to the outer tube against the action of the spring means for establishing the degree to which the radial openings in the outer tubes are covered by the inner tube.
Claim 3
Dependent Claim
51 words
A combined mixer and dispenser apparatus according to claim 1 including a motor connected to the shaft for driving the impeller, a housing to which the outer tube is rigidly connected and on which the motor is mounted, the impeller being located inside the outer tube adjacent its open axial end.
Claim 4
Dependent Claim
40 words
A combined mixer and dispenser apparatus according to claim 2 wherein the inner tube is urged by the spring means to a terminal axial position at which the radial openings in the outer tube are uncovered by the inner tube.
Claim 5
Dependent Claim
48 words
A combined mixed and dispenser apparatus according to claim 3 including a discharge conduit connected to the outer tube, the inner tube having a discharge orifice opening into the discharge conduit when the inner tube is positioned so as to cover the radial openings in the outer tube.
Claim 6
Dependent Claim
61 words
A combined mixer and dispenser apparatus according to claim 4, wherein the housing has means for effecting its attachment to a container holding the liquid to position the axial ends of the tubes within the liquid whereby mixing or dispensing of the liquid can be carried out depending on the axial position of the inner tube relative to the outer tube.
Claim 7
Dependent Claim
63 words
A combined mixer and dispenser apparatus according to claim 5 wherein the axial end of the inner tube is provided with an annular flange within which the impeller is rotatable, such flange being cooperable with the radial openings in the outer tube to control the flow of liquid therethrough, depending on the axial position of the inner tube relative to the outer tube.
Claim 8
Dependent Claim
47 words
A combined mixer and dispenser apparatus according to claim 6 wherein the two tubes are provided with shoulders which limit the axial displacement of the inner tube relative to the outer tube and cooperate with the spring means for defining the normal position of the inner tube.
Claim 9
Dependent Claim
54 words
A combined mixer and dispenser apparatus according to claim 7, wherein the inner tube is provided with extensions projecting into the housing, and an operating cylinder coaxial with the tubes is engaged with the extensions and is manually displaceable for the purpose of moving the inner tube against the action of the spring means.
Claim 10
Dependent Claim
19 words
A combined mixer and dispenser apparatus according to claim 8 used for the purpose of mixing and dispensing cocktails.
