 BACKGROUND OF THE INVENTION l. Field of the Invention Our present invention pertains to a combination drink mixing and dispensing appliance which not only mixes drinks in a container but also dispenses the mixed drinks through a pump device to glasses or the like positioned alongside of the container.  
 2. Description of the Prior Art Drink mixers of all types are well known in the art but. to the best of our knowledge, there have been no combination appliances developed which combine a drink mixing feature with a drink dispensing feature as disclosed in our present invention. In all drink mixers of which we are aware. after a drink has been mixed in a container. the mixed drink is merely poured from the container into a glass or the like. Siphon arrangements may have been used in the past but, as far as we know. no centrifugal pump arrangements have been developed for use in dispensing mixed drinks from a container wherein the drink mixing agitator serves as the impeller for the pumping arrangement, as disclosed herein.  
 SUMMARY OF THE INVENTION The present invention is concerned with a combination drink mixing and drink dispensing appliance wherein a drink may be mixed in a container and (lispensed from the same container into a glass or the like disposed or held alongside the container without physically handling the container. as in a pouring operation. The appliance has a base portion upon which is supported a container having an impeller-like agitator mounted in its bottom with a drive shaft for the agitator projecting below the container bottom and being engageable with drive means provided in the base portion. The appliance also has a dispensing portion which includes a pump housing having upper and lower chambers and an open bottom whereby same may be fitted over impeller-like agitator. The pump housing is provided with inlet openings for the lower chamber and the upper chamber is in communication with a delivery tube arrangement including a vertically disposed tube having a horizontally disposed transfer tube connected to its upper end and with the transfer tube being adapted to project beyond the upper edges of the container and having a downwardly directed dispensing spout provided at its outer end. The pump housing is provided with a series of peripheral slots which provide communication between the upper and lower cham bers of the pump housing with the leading edges of the slots being inclined upwardly and forwardly. in the direction of rotation of the agitator. and having a concave configuration to aid in centrifugal pumping ofthe mixed drink from the lower chamber into the upper chamber and through the delivery tube arrangement during operation of the agitator.  
  It is an object of the present invention to provide a new and novel combination drink mixing and dispensing appliance.  
  It is a further object of the present invention to provide such a combination appliance wherein a drink may be mixed and dispensed from the same container without physically handling the container as during a pouring operation.  
  It is still a further object of the present invention to provide such a combination appliance including a container having an impeller-like agitator. and a pump and delivery apparatus which utilizes the agitator as a pump impeller for dispensing the mixed drink to a delivery point external of the container.  
  Another object of the present invention is to provide such a combination appliance wherein a portion of the delivery apparatus is interengageable with the upper edge of the container for greater stability.  
  Yet another object of the present invention is to pro vide such a combination appliance wherein the pump housing is characterized by upper and lower chambers with the agitator being operable in the lower chamber. which chamber is open at its lower end. to centrifugally pump a mixture of liquids from the lower chamber to the upper chamber through a series of peripheral slots formed in the pump housing and extending between the two chambers. and thence. through the delivery apparatus to a glass or the like.  
  A still further object of the present invention is to provide such a combination appliance wherein the leading edges of the peripheral slots provided in the pump housing are inclined upwardly and forwardly. in the direction of rotation of the impeller-like agitator. and are provided with a concave configuration whereby the mixture being pumped from the lower chamber is given an upward swirling motion.  
  Further objects and advantages of the present invention will become apparent as the following description proceeds. and the features of novelty which character ize the invention will be pointed out with particularity in the claims annexed to and forming a part of this specification.

The combination appliance 20 includes a generally L- shaped housing 22 having a vertical leg portion 24 and a horizontal leg portion 26. A drink mixing and dispensing container 28 is supported on the horizontal leg portion 26 of the L-shaped housing in a manner to be described. Although it forms no part of the present invention and is now shown in the drawings, a vertically disposed ice crushing mechanism may be provided in the vertical leg portion 24 of the housing 22 for dis pensing crushed ice directly into the container 28. Such an ice crushing mechanism is disclosed in US. application Ser. No. 226,157 filed Feb. 14, 1972. As shown in the above-identified pending application. an electric motor (not shown in this application] is provided in a lower portion ofthe vertical leg portion 24 of the housing 22 for actuating the ice crushing mechanism.  
  The housing 22, which may be molded in one piece of plastic, is characterized by from and back L-shaped walls 30, by an integral end wall 31 for the vertical leg portion 24. by an integral end wall 32 for the horizontal leg portion 26, and by an integral vertical wall 33 intermediate the vertical and horizontal leg portions 24 and 26. respectively The open bottom of the housing 22 is closed by a thin metal plate 34 which has suitable supporting feet or pads 35 secured thereto.  
  A containenreceiving cavity or dished-out recessed portion 37 is defined in the horizontal leg portion 26 of the housing 22 by a bottom wall 38 which is spaced approximately between the upper and lower edges of horizontal leg portions 40 and 41 of the L-shaped front and back walls 30. The integrally formed bottom wall 38 blends into the lower edge of the intermediate wall 33 and into the inner surfaces of the end wall 32 and the horizontal leg portions 40 and 41 of the Lshaped front and back walls 30 with a gentle curvature approximately midway between the upper and lower edges thereof.  
  For supporting the container 28 in the dished-out recessed portion 37, the front and back wall sections 40 and 41 are each provided on their inner surfaces with a pair of vertically disposed integral ribs 42. Although not shown in HQ. 6. the end wall 32 is preferably provided on its inner surface with a similar vertical rib. the upper surfaces of all of said ribs being spaced above the bottom wall 38 and adapted to support the bottom edges of the container 28 whereby same is supported above the bottom wall 38 ofthe dished-out recess portion 37 for a reason which will be made clear hereinafter.  
  The bottom wall 38 of the containenreceiving cavity 37 is provided along its longitudinal center line with an integral boss 44 which extends both above and below the bottom wall 38 and which has a vertical bore 45 formed therein. As disclosed in the previously men tioned US, application Ser. No. 226.157. filed Feb. [4. 1972. the boss 44 may be off-center relative to the end walt 32 and the intermediate vertical wall 33 of the housing 22. A sleeve bushing 46 is provided in the bore 45 and has a shaft 47 rotatably mounted therein. An 0- ring 48 is provided at the upper end of the bore 45 and a coupling member 49 having a series of upwardly projecting right-trianguiar clutch teeth 50 is press fitted on the upper end of the shaft 47.  
 LII  
  A pulley S1 is press fitted on the lower end of the shaft 47 and a drive belt 52 extends around the pulley 5] and is drivingly connected to a suitable electric motor (not shown) which may be provided in the vertical leg portion of the housing 22. Preferably, the drive ratio between the electric motor and the coupling member 49 should be in the order of 1:1. The electric motor may be controlled by a suitable on-off switch 53 FIG. 1). The bottom plate 34 of the housing 22 is provided with an opening 54 which accommodates a hub portion 55 of the pulley 51.  
  The drink mixing container 28 is generally rectangu lar in configuration and is characterized by front and back Walls 58, end walls 59 and an integral bottom wall 60 which is spaced above the lower edges of the walls 58. 59 and which slopes generally conically down wardly from the walls 58, 59 to facilitate the feeding of ingredients into the agitator to be described hereinaf ter. The bottom edges ofthe walls 58, 59 are supported on the ribs 42 in the container-receiving recess 37 whereby the container 28 is supported above the bottom wall 38 of the containerreceiving cavity 37.  
  As is apparent, the container 28 may be positioned in the container-receiving recess 37 in either of two 180 reversed positions. The bottom wall 60 ofthe container 28 is formed with an upstanding boss 62 which is centered relative to the fromt and back walls 58 of the container but which may be off-center relative to the end walls 59 of the container 28. However. in one of the two possible positions of the container 28 in the container-receiving recess 37. the boss 62 must be vertically aligned with the boss 44 of the container receiving recess 37.  
  The boss 62 is provided with a vertical bore 63 in which is mounted a sleeve bushing 64. a shaft 65 is ro tatably mounted in the sleeve bushing 64 and has an impeller-like drink-mixing agitator 67 secured to the upper end of the shaft 65 by means of forming-over the end of the shaft 65. An O-ring 69 is provided at the upper end of the bore 63 to prevent leakage of liquids from the container 28. The agitator 67 is characterized by a pair of diametrical flutes 70 disposed perpendicular to one another and by downwardly inciined mixing arms or blades 71 which insure adequate mixing of a minimum amount of liquid. such as for a single drink.  
  The lower end of the agitator shaft 65 extends slightly below the bottom wall 60 of the container 28 and has a coupling member 72 press fitted thereon. The coupling member 72 is provided with a series ofdepending right-triangular clutch teeth 73 and is identical to the coupling member 49 mounted on the drive shaft 47. When the container 28 is disposed in the containerreceiving recess 37 with its boss 62 vertically aligned with the boss 44 provided in the container-receiving recess 37. the two coupling members 72 and 49 are disposed in meshed driving engagement. The container coupling member 72 does not depend below the bot tom edges of walls 58. 59 of the container 28 whereby to insure stability of the container 28 when same is placed on a table or counter top.  
  The pumping and delivery tube portion of the present invention includes. as is best illustrated in P10. 2, a lower pump housing 75. an upper pump housing 76. a \crtical tube 77, and a horizontally disposed transfer tube 78. These four parts may all be formed of modified styrene (NAS) which has the necessary properties of strength. impact resistance and ability to hold di mensional tolerances as well as suitable food handling characteristics.  
  The two pump housings 75 and 76 are telescopically assembled. as shown in FIGS. 3 and 6, to provide a pump housing having an upper chamber 80 and a lower chamber 81. The lower pump housing 75 is in the form of an inverted handleless cup and is characterized by an open bottom, by a top wall 83, and by a generally cylindrical side wall 84 having the upper portion 85 adjacent the top wall 83 offset inwardly whereby to define an upwardly facing annular shoulder 86.  
  The upper pump housing 76 is in the form of an inverted funnel with an upwardly projecting axially bored neck portion 88, a conical top wall portion 89, a de pending cylindrical skirt portion 90 and an open bottom. When the upper and lower pump housing are telescopically assembled, the skirt portion 90 of the upper pump housing 76 is fitted over the inwardly offset upper portion 85 of the of the lower pump housing 75 with the bottom edge of the skirt portion 90 being seated against the shoulder 86. The upper and lower pump chambers 80 and 81 are defined in part by the top wall 83 of the lower pump housing 75. a series of vertically disposed circumferentially spaced outer ribs 92 provided on the inwardly offset upper portion 85 of the lower pump housing 75 serves to provide a tight but non-binding fit between the upper and lower pump housings whereby to facilitate both assembly and disassembly thereof for cleaning purposes.  
  The inner diameter of the lower pump housing 75 is somewhat larger than the impeller-like agitator 67 whereby the open-bottom lower pump housing may be fitted thereover with the agitatior 67 being disposed within the lower pump chamber 81. An annular guide shoulder 91 is formed on the bottom wall 60 ofthe container as an aid in centering the lower pump housing 75 over the agitator 67. Fluid communication betweeen the lower pump chamber 81 and the liquid contents of the drink mixing container 28 is provided by a series of notch-like inlet ports 93 formed in the bottom edge of the side wall 84 of the lower pump housing 75 in circumferentially spaced relationship. Fluid communication between the pump chambers 80 and 81 is provided by a series of peripheral slots 94 to be described in detail hereinafter.  
  When assembled. the vertical tube 77 is fitted into the neck portion 88 of the upper pump housing 76 and seated against a shoulder 95 formed therein. The upper end of the vertical tube 77 terminates at a level slightly below the upper edges of the container walls 58, 59. One end 96 of the transfer tube 78 is turned downwardly and is adapted to receive the upper end of the vertical tube 77 which is seated against a shoulder 97 formed therein. The opposite end of the transfer tube 78 is turned downwardly to define a pouring spout or dispensing nozzle 98 for dispensing mixed drinks at a point outside of the container 28.  
  Intermediate the turned down portion 96 and the dispensing nozzle 98. the transfer tube 78 is provided on its upper side with a pair of spaced ribs 99 which are adapted to be fitted over the upper edge of one of the container walls 58 to provide additional stability for the pumping and delivery tube portion of the present invention. To facilitate cleaning of the transfer tube 78, it may be formed with an elongated opening 101 in its upper surface. A separate cover 102 is then provided which is adapted to be snapped into place in the opening 101.  
  Referring again to the peripheral slots 94 provided in the lower pump housing 75, it is noted, as best shown in FIGS. 3, 5 and 6, that four peripheral slots 94 are circumferentially spaced around the inwardly offset wall portion 85. Using the direction of rotation of the impeller-agitator 67 as a reference, the trailing edge 104 of each slot 94 is disposed vertically and is tapered outwardly in a forward direction to the outer surface of the wall portion 85. The leading edge 106 of each slot 94 is inclined upwardly and forwardly and is provided with a generally concave configuration. The upper edges of the peripheral slots 94 open through the top wall 83 of the lower pump housing and thus into the upper pump chamber 80.  
  Thus, with the pumping and delivery assembly in position over the impeller-like agitator 67, during actuation of the agitator the mixed liquids in the container 28 are drawn into the lower pump chamber 81 through the inlet ports 93 and are centrifugally pumped upwardly through the peripheral slots 94 into the upper pump chamber with the slot design described herein imparting an upward swirling motion to the pumped liquid. The pumped liquids then pass through the vertical tube 77 and the transfer tube 78 to the dispensing nozzle 98, as shown by the arrows in FIG. 6.  
  Should it be desirable to use the drink mixing appliance 20 disclosed herein without the drink dispensing portion thereof. the container 28 is provided at one of its upper corners with a pouring spout configuration 108 FIG. l). Although not shown in the drawings. the container 28 is preferably provided with a removable cover which serves to prevent spillage during the mixing of drinks, particularly when a larger volume of drinks is being mixed. Such a cover may be provided at one corner with a strainer configuration adapted to be positioned adjacent the pouring spout 108. The container 28 disclosed in the drawings may hold up to three pints ofliquids and. although not shown. suitable measuring indicia may be molded on the container itself. In addition, portions of the side walls of the container 28 may be roughened and preformed to provide a slip-resistance hand grip configuration to facilitate manual pouring operations.  
  Although the combination appliance 20 may be used most often to prepare mixed alcoholic drinks. it is noted that it may also be used for the preparation of frozen juices, milk shakes and malts, instant breakfast, sauces and dressings of all types. etc.  
  While there has been shown and described a single embodiment of the present invention, it will be apparent to those skilled in the art that various changes and modifications may be made without departing from the invention in its broader aspects and it is, therefore, contemplated in the appended claims to cover all such changes and modifications as fall within the true spirit and scope of the present invention.
