Definitions

  • 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 centrifugal-type 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.
  • a spring'actuated one-way clutch is used to engage or disengage the housing or the impeller, and the spring has a downwardly pointing end to engage a wedge-shaped groove in the rotatable housing. This end is biassed onto the housing and increases friction on the housing. Moreover, said end of the spring can cut into the housing and eventually prevent rotation thereof. It is an object of the invention to mitigate the above disadvantages.
  • a device including a housing having a gear chamber with an inlet andan outlet, a gear pump in the chamber, a centrifugal-type agitator, a pawl-type ratchet mechanism to actuate the agitator, and a drive member, the ratchet,
  • pump and agitator being constructed and arranged in such a manner that rotation of the drive member in one direction causes the means to be engaged and thus causes the agitator to rotate, and in the opposite direc-, tion causes the ratchet to be disengaged and the pump to pump a liquid from the inlet to the outlet.
  • gear pump As the pump is a gear pump, the rotation of the drive member in the first direction simply reverses the pumping action of the gear pump and terminates pumping of the liquid.
  • a suitable gearmeans can be constructed to drive the ratchet, and the gear means or part of the gear means may form the gear wheels of the gear pump.
  • the agitator may be of any desired shape or form, and may be provided with blades in a suitable manner to liq uidise matter about the device.
  • the possible uses of the device and various forms of agitator blade will be restricted by the strength of the materials used to form the device and also by the driving force applied to the drive member.
  • the device can advantageously be used in a domestic liquid mixer, such as a cocktail mixer. With correct design of such mixers it is possible for the device to mix and dispense blended liquids in response to simple manual operation, for example the depressing of an appropriate button.
  • the device can beused in combina: tion with an electric motor, and, depending on the use for which it is intended, may be operated by a battery or a mains supply voltage. It will be appreciated that a battery operated domestic mixer including a device ac cording to the invention will have no plugor cord and will not be dependent on mains supply voltage. It will betherefore be particularly suitable for any situation, in which the mixer is intended to be portable, for example when travelling.

  • the batteries are not shown.
  • a control switch arrangement including two supporting walls 36, a switch member pivotable on pins passing into the wall and contacts 48.
  • the arrangement includes a circuit formed such that when the member 38 is depressed at one side the associated set of contacts closes one part of the circuit and the motor is driven in one direction, and when the member 38 is depressed at the other side similar circuitry causes the motor to be driven in the opposite direction.
  • the wiring system of the circuit used with the motor and the switching arrangement is not shown but will be apparent to one skilled in the art.
  • a cover 5 encases the support 4 and includes manually operable means for permitting either end of the member 38 to be depressed as desired.
  • Two housings 50in the cover are arranged so that two rods 52 extending from the housing press one on each end of the .member 38 such that when either one of the rods is depressed the member 38 will cause the opposite contact on the member 38 to be closed to those which are closed when the other rod is depressed.
  • Buttons 54 are fixed on the rods 52 and are prevented from moving from the housing by rings 72 fixed in the cover. The rods 52 are biased to a position in which they do not depress the member 38 by springs 56 pressing against the buttons.
  • the cover 5 has in it a slot 58 to co-operate with ring 28 on the cap 3 and also has slots 60.
  • a projection 66 on a member 64 which holds the cover over the support 4 passes through the hole 60.
  • the member 64 is fixed to plate 32 of the support 4 and is resiliently biased in a direction away from the motor N.
  • Projections 68 on member 64 co-operate with projections 62 on the cover 5 to hold the cover in place. To remove the cover, it is necessary to press the projections 66 inwardly towards the motor so that projections 68 and 62 no longer co-operate. The cover can then be removed from around the support 4.
  • the member fixed in the sleeve 44 passes through a sealing ring 30 which prevents fluid passing upwardly through the tube 10 and part 12 from leaking into the portion 18 of the cap 3.
  • a plate 35 having an aperture ofa suitable size therein can be used to' prevent sleeve 44 from causing the drive shaft 100 to oscillate during rotation of the motor.
  • the liquid mixer and dispenser includes a device according to the invention for mixing a liquid in the mixing jar and for pumping the liquid upwardly through the tube 10 and to the outlet 16.
  • the device has a tube 101 which, according to the simplicity of its production and its size, can be connected to, in or about the tube 10 of the cap 3.
  • the drive shaft 100 extends through the tube 101.
  • the tube 101 is fixed in or is integral with a housing 113.
  • the two ends of the housing 113 are substantially closed by a member 111 forming an agitator and by a plate 127.
  • the member 111 is held slidably against a co-operating portion of the housing 113 by a ring 103 fixed about the tube 101.
  • the member 111 encircles and is rotatable about the tube 101.
  • Fins 105 are in-' cluded on the outer portion of the member 111 and, in use, are used to agitate fluid about the member.
  • a projection 108 on the inner face of member 111 is used to enable the member to be rotated. This projection 108 can be engaged by a pawl 109 of the ratchet on a rotatable member 107 when the member 107 rotates in one direction. When the member 107 rotates in the opposite direction the projection 108 is not engaged by the pawl 109 and no positive driving force is exerted on the member 111 by the pawl.
  • the member 107 encircles and is rotatable about the tube 101 and has a gear wheel fixed to or formed integrally with it.
  • the gear wheel engages a gear wheel on a shaft or axle 131.
  • the shaft 131 passes through a guide hole in the housing 113 and is connected at its other end to a gear wheel 123.
  • the gear wheel 123 engages a gear wheel 121 which is fixed on the drive shaft 100.
  • the drive system can be seen in FIG. 11, in which the housing, member 111, and plate 127 are shown.
  • the drive shaft is operable on the gear wheel 121 which in turn is operable on the gear wheel 123 which drives shaft 131 and gear wheel 115.
  • the gear wheel 115 engages the gear wheel on the lower portion of member 107 and drives member 107 accordingly.
  • the pawl 109 rotates with the member 107.
  • the wheels 123 and 121 are in the chamber 150 of the housing 113 and the two wheels and the chamber form a gear pump.
  • the gear pump is arranged so that when wheels 121 and 123 rotate in one direction fluid is drawn into one side of the chamber through aperture 125 and is passed out of the chamber from the opposite side through a hole (not shown) leading to the chamber 133.
  • the fluid in the chamber 133 can pass from the chamber 133 through the tube 101 into the tube 10.
  • the chamber 133 and tube 101 thus form a passage from the pump and through the housing.
  • the gear pump no longer serves to force fluid from the aperture 125 upwardly through the tube 101 but the pawl 109 engages projection 108 and thus cause the member 111 to be rotated and fluid in the mixing jar to be mixed.
  • a fluid in the mixing jar can be mixed or pumped through the tube 101 and to the outlet 16 merely by changing the direction of rotation of the motor.
  • the device described it is possible for the device described to be made almost completely of plastics materials. It is preferred, however, for at least the drive shaft and advantageously the axle to be formed of metal.
