8 Claims, 4 Drawing Figures PATENTEDIAY 7 1974 fllll 1 ICE CUBE DISPENSING MACHINE FIELD OF THE INVENTION The present invention relates to an ice cubedispenser which is adapted to store ice cubes while keeping the cubes separated from each other and to dispense one or more ice cubes at a time, as desired.
BACKGROUND OF THE INVENTION Every home, restaurant, or bar makes use of ice cubes stored in dispensers. For example, in the home, ice cubes are normally made in the freezer of a refrigerator and stored in the freezer until ready for use. The ice cubes may be removed from the freezer and used directly or may be stored in an insulated storage unit prior to use. In restaurants of bars, ice cubes are normally prepared in a freezer and removed therefrm and stored in large containers prior to use.
It has been found that when ice cubes are stored in conventional storage units, the ice cubes tend to stick to one another and cannot be removed from the storage unit one at a time. It is usually necessary to remove two or three or more ice cubes, all stuck toether, and
separate thecubes from each other.
Commercial ice cube making and vending establishments have recognized this problem for some time and have apparently solved it. To do so, they have developed complex commercial ice cube making and vending machines which normally comprise means formaking ice cubes and means for storing the cubes which include means for keeping the cubes separated from each other. The means for keeping the cubes separated usually comprises a rotatable shaft which includes a plurality of spikes positioned thereon; as the shaft rotates, the spikes contact the ice cubes and keep them separated from each other, but do not aid in moving the ice cubes from the storage means to an outlet or dispensing means. The shaft and associated spikes are usually part of a complex and expensive piece of equipment which is suitable for home use and even in small business establishments. For example, US. Pat. No. 3,18,958 to Swart discloses an ice cube vending machine which includes an anti-bridging device which comprises a bin element having converging walls and a curved bottom wall; the bin includes an elongated feed screw element driven by an electric motor and a shaft having a plurality of spikes extending therefrom positioned above the feed screw element. The shaft functions to keep the ice cubes separated as they fall onto the screw element which moves the cubes to dispensing means. The shaft carrying the plurality of spikes is vertically disposed within the vending machine.
US. Pat. No. 3,217,509 to Weil, et. al discloses a horizontally-disposed rotatable shaft in combination with complex ice making and vending apparatus. This apparatus is not for dispensing ice Cubes but is designed to dispense crushed ice.
US. Pat. No. 3,146,915 to Gregor discloses a vibratory transfer chute which includes a horizontallydisposed .rotatable shaft having a plurality of teeth extending therefrom. The chute is essentially for transferring non-free flowing materials such as macaroni, vegetables and the like from scaling or measuring devices, without bridging or clogging the chute.
A number of other patents disclose a rotatable shaft having teeth, angular bars, or spikes disposed thereon 2 which could be employed for keeping ice cubes separated from each other. Each of these patents has one thing in common, namely that the rotatable shafi is dis posed vertically within a housing and thus the shaft does not aid in 'moving ice cubes to dispensing means. Examples of some of these patents are US. Pat. No. 2,353,132 to Frank; US. Pat. No. 3,075,363 to Conto; US. Pat. No. 3,101,872 to Dickinson; U.S.'Pat. No. 3,144,965 to Burton et 2.1.; U5. Pat. No. 3,196,628 to Reynolds and Pat. No. 3,608,786 to Shelly et al.-
None of the above-mentioned dispensers is adapted to be employed in the home or in small eating or drinking establishments for dispensing ice cubes one or more at a time, as desired.
BRIEF STATEMENT OF THE INVENTION In accordance with the present invention, there is provided an ice cube dispenser which stores ice cubes while keeping the cubes separated from each other and dispenses cubes one or more at a time, as desired by the user. The dispenser of the invention is of simple and inexpensive construction, easy to maintain, but surprisingly efficient and is adapted for use in the home or at restaurants or bars or other establishments where ice cubes are stored and dispensed.
The ice cube dispenser in accordance with the invention comprises a storage member having a chamber therein for storing ice cubes, said storage member including an inlet and outlet for ice cubes, a rotatable moving member horizontally disposed within said chamber for keeping the ice cubes from sticking to one another and moving the ice cubes to the outlet in the storage member and 'means for rotating said moving member.
In a preferred embodiment of the invention, the rotatable moving member comprises a shaft horizontally disposed in said chamber, said shaft having a plurality of angular bars extending therefrom; the shaft is rotated by-driving means such as a motor which can run on batteries, or be plugged into an electric outlet.
The storage member and chamber therein are provided with openings for receiving ice cubes to be stored in the chamber and for dispensing ice cubes; In a preferred embodiment of the invention, the openings comprising the outlet for dispensing the ice cubes is separated from the inlet opening and includes cover means which are mounted over the opening, said cover means being movable between open and closed positions, during which ice cubes may be dispensed through the opening or retained in the chamber by the cover, respectively.
The ice cube storage member is preferably positioned within a housing, which includes a removable or hinged top cover positioned over the inlet opening in the storage member. The housing will also include openings aligned with the outlet openings in the storage member.
The ice cube dispenser of the invention thus may take the form of a compact machine, which may be portable or may be permanently secured to a support such as a ledge, shelf or table top; where the dispenser is permanently secured to a support, the openings in the housing corresponding to the outlet and covers therefor in the storage member will preferably extend over said ledge, shelf or table. In this embodiment, when an ice cube is desired, a glass or other container be released or moved into the closed position.
DESCRIPTION OF THE FIGURES FIG. 1 is a perspectiveview of an ice cube dispensing machine in accordance with the invention.
FIG. 2 is an exploded view of the various components of the ice cube dispensing machine shown in FIG. 1.
FIG. 3 is a front view of the ice cube dispensing machine shown in FIG. 1 which shows by phantom lines the various components making up the dispenser.
FIG. 4 is a side view of the ice cube dispenser shown in FIG. 1.
Referring to the various Figures, wherein like numerals represent like parts in the several views, the numeral generally refers to the ice cube dispenser of the invention, which includes a housing 12 having a removable top 14 connected to the top of the housingas shown. The removable top 14 may be completely removed from the housing 12, or the back edge of the top cover may be hinged to the housing 12 by hinge 16 as shown in FIG. 4 as will be apparent to one skilled in the art.
The housing 12 also includes recessed openings 18 and 20 as shown.
Within the housing 12, there is positioned storage member 22 which as shown is preferably in the form of a cylinder including end sections 23, 24, an open top 25 through which ice cubes may be filled, openings 26 and 28 through which ice cubes may be dispensed and a storage compartment or chamber 30. It will be understood that the dispenser of the invention may have any number of outlet openings. As shown, the outlet openings 26, 28 as well as any other outlet openings which may be present) include cover means 32 which may take the form of metal strip 34 having a tab 36, the strip being secured to the storage member 22 by brackets 38, 39 as shown. In the embodiment shown, the metal strip is adapted to slide in the brackets 38, 39 to open and close off the openings 26, 28. The cover means can be speing loaded to facilitate movement between the open and closed positions. The tab 36 of the metal strip 34, or the metal strip 34 itself, can be con-' nected to the storage member 22 by spring means 40 which are secured for example, by screws, to the cover means and storage member 22. The use of the springs 40 is not essential and is only optional.
The end section 24 of the cylindrical storage member 22 has a central opening 52 through which shaft 54 having angular bars 56 extending therefrom is positioned. The shaft 54 is in operative communication with motor 60 and reduction gear housing 60a, as shown. As seen in FIGS. 3 and 4, the angular bars 56 form two sets, the first set of alternating bars lying in a first plane with the bars being parallel to each other and the second set of alternating bars lying in a second plane perpendicular to the first plane with the bars being parallel with each other. Each set of angular bars is skewed from the shaft 54, to form acute angles between adjacent bars. The shaft 54 and angular bars 56 are designed to fit in the chamber of storage mem-,
'ber 22 with the end 62 of shaft 54 fitting in a mount or opening64 in end section 23 of the storage unit 22. The
end section 24 of storage unit 22 is designed to fit on the open end of the storage unit 22 and be secured thereto by clamps 70 or other conventional means which lock the end section 24 in place.
The storage unit 22 is mounted on mounting means 80 which is supported on bottom plate 82 of the housing 12. As shown in FIG. 1, bottom plate 82 may be secured to ledge or shelf 90 by screws or other conventional means.
The ice dispensing erates as follows:
The ice dispensing machine is filled with ice cubes'by lifting the top cover 14 from the top of the'housing 12 along hinge 16; ice cubes are fed-through opening 25 in storage member22 into chamber 30. At this time, the covers 32 are in a closed position over the outlet openings 28- and 26. In addition, the shaft 54 having angular bars 56 extending therefrom is made to rotate by energizing motor means 60. The ice cubes are loaded into the storage member 22 until the chamber 30 is loosely packed with ice cubes. It will be apparent that the ice cubes should be loosely packed into the chamber 30 so that the shaft 54 and angular bars 56 may romachine shown in the figures optate without breaking up the ice cubes or burning out the motor means 60.
As the shaft 54 and the angular bars 56 rotate in chamber 30, the bars contact the ice cubes stored therein and continually cause the ice cubes to move and rotate within the chamber while keeping the ice cubes separated from each other. Furthermore, the bars 56 help move ice cubes along the shaft54. Thus, when ice cubes are removed through openings 26, 28 of chamber 30, the angular bars 56 will automatically move other rotating ice cubes horizontally along the shaft 54 until the cubes reach the openings 26, 28. v
Whenan ice cube is desired, a container, such as a glass is positioned under one of the openings 18 or 20 in the housing. Cover 32 extending out from the opening 18 0r 20 and positioned over the opening 26 or 28, respectively, is moved into an open position by pushing the glass against the tab 36 and causing the metal strip 34 to slide in the brackets 38, 39 down and away from the operator. As the'cover 32 is moved away from the opening 26 or 28, the springs 40 assumea biased state. After the cover 32 isfully opened, tab tube 36 is held to keep the springs 40 biased and to prevent the cover from springing closed. Ice cubes will fall through the openings into the container. When the desired number of cubes is dispensed, the tab 36 is released and the action of the spring 40 moving to an unbiased position will cause the cover means 32 to return to a closed position. it
It will be apparent that the ice cube dispensing machine shown in the Figures is for illustrative purposes only. The housing 12 may be of many different shapes such as rectangular, square, circular, oval, triangular and the like. The housing as well as the storage member 32 and shaft 54 may be made from any durable solid material such as plastic, wood or metal. The storage member 22 may be in cylindrical form as shown or any other desired shape as long as the shaft 54 having the angular bars 56 extending therefrom may be horizontally disposed in the storage member 22 and the angu- I keeping the ice cubes separated from each other and moving the ice cubes along a horizontal path to the openings 26, 28 and dispensing means of the storage member 22.
It will also be appreciated that the angular bars 56 actually cause ice cubes to pass just above the opening 26 or 28, and the bars 56 actually push the ice out of the openings into the glass. This is in contrast to theuse of a chute wherein non-moving ice cubes stick together and cause the chute to become clogged.
The storage member 22 is preferably of cylindrical shape so that any pockets of non-moving ice which could build up in corners if the storage member were of square or rectangular configuration, is avoided.
The ice cube dispensing machine of the present invention can take all standard type ice cubes.
