Abstract
Abstract This invention relates to an improved agitating and pumping device, comprising: a housing; a gear chamber in said housing; an inlet and outlet for said chamber; a pair of gears in said chamber for pumping liquids through said chamber; a centrifugaltype agitator supported by said housing; a pawl-type ratchet mechanism to actuate the agitator; and a drive member to effect rotation of the gears and the agitator; wherein rotation of the drive member in one direction causes the ratchet mechanism to be engaged and thus causes the agitator to rotate, and in the opposite direction causes the ratchet mechanism to be disengaged and the pump to pump a liquid from the inlet to the outlet.

Claim 2
Dependent Claim
141 words
An improved agitating and pumping device comprising: a stationary housing having a gear chamber for a gear pump, said chamber having an inlet and an outlet; an agitator rotatable with respect to said housing; ratchet means to actuate the agitator when rotated in a first direction and to disengage the agitator when rotated in a second direction; a drive member to effect rotation of the said pump and said ratchet means; an electric motor; means to energize said motor, thereby to effect rotation of the drive member in one of two directions; a plurality of gears driven by the drive member, two of said gears being the gears of the said pump; a cap on said housing and forming said agitator, said agitator being of the centrifugal-type; and a hole formed in said cap, said drive member passing through said hole.
Claim 3
Dependent Claim
64 words
The device of claim 1, wherein said energizing means comprises two sets of contacts each of which can be closed separately to selectively effect rotation of an output shaft of the motor in opposite directions, said output shaft being connected to said drive member; and two buttons each associated with one set of contacts and each of which, when depressed, closes the associated contacts.
Claim 4
Dependent Claim
162 words
An improved agitating and pumping device, comprising: a housing; a gear chamber in said housing; an inlet and outlet for said chamber; a pair of gears in said chamber for pumping liquids through said chamber; a centrifugal-type agitator supported by said housing; a pawl-type ratchet mechanism connected to one of said pair of gears and operative to actuate the agitator; a drive member to effect rotation of the gears and the agitator; two sets of contacts, each of which can be closed separately to effect rotation of an output shaft of the motor in opposite directions; and two buttons associated with each set of contacts and each of which, when depressed, closes the associated contacts; wherein rotation of the drive member in one direction causes the ratchet mechanism to be engaged and thus causes the agitator to rotate, and in the opposite direction causes the ratchet mechanism to be disengaged and to thereby pump a liquid from the inlet to the outlet.
Claim 5
Dependent Claim
162 words
An improved agitating and pumping device, comprising: a housing; a gear chamber in said housing; an inlet and outlet for said chamber; a pair of gears in said chamber for pumping liquids through said chamber; a centrifugal-type agitator supported by said housing; a pawl-type ratchet mechanism connected to one of said pair of gears and operative to actuate the agitator; a drive member to effect rotation of the gears and the agitator; two sets of contacts, each of which can be closed separately to effect rotation of an output shaft of the motor in opposite directions; and two buttons associated with each set of contacts and each of which, when depressed, closes the associated contacts; wherein rotation of the drive member in one direction causes the ratchet mechanism to be engaged and thus causes the agitator to rotate, and in the opposite direction causes the ratchet mechanism to be disengaged and to thereby pump a liquid from the inlet to the outlet.
Claim 6
Dependent Claim
149 words
In a mixer and pourer for beverages having a jar, a support on said jar, a motor supported by said support, and drive means to be driven by said motor, the improvement comprising an agitating and pumping device having a stationery housing for a first gear wheel on said drive means, a second gear wheel engaging said first gear wheel, a third gear wheel mounted on a common axle with and rotatable with the second gear wheel, a fourth gear wheel engaging the third gear wheel, a fourth wheel being associated with a rotatable member having a pivotable pawl thereon, the pawl being disposed and arranged to engage or not to engage a projection extending from the agitator, depending on the direction of rotation of the rotatable member, two of said gear wheels forming a gear pump for pumping said beverages when said pawl is disengaged from said projection.
Claim 7
