Application December 28, 1945, Serial N o. 637,703

This invention relates to dispensing devices and more particularly to a device for dispensing glasses of cold drinking water for use in dining rooms, cafeteras and similar establishments.

A main object of the invention is to provide a novel and improved water dispensing device of relatively simple construction wherein means is provided for supplying chilled and sterilized glasses to a location adjacent the water outlet whereby a minimum of effort is required to ll the glasses with water.

A further object of the invention is to provide an improved water dispensing device embodying a refrigerated cabinet which may be employed for storing additional articles such as saucers, butter, cream and the like, as are likely to be required in dining rooms, restaurants, cafeteras and similar establishments, said cabinet including a controllable conveyor device for feeding glasses to the user as required, said glasses being previously chilled and sterilized in the cabinet.

Further objects and advantages of the invention will become apparent from the following description and claims, and from the accompanying drawing, wherein:

Figure 1 is a front elevational view partly in cross-section of a drinking water dispensing device constructed in accordance with the present invention.

Figure 2 is a top plan View of the dispensing device of Figure 1, partly broken away to show interior details of construction.

Figure 3 is a side elevational view partly in cross-section of the dispensing device of Figure 1.

Referring to the drawings, I I designates a cabinet which is substantially rectangular in shape and is adapted to be supported on detachable legs I2 provided at each corner of the cabinet. Cabinet II is formed with thermally insulated top, bottom, rear and side walls defining a storage compartment I3 of substantial size containing a plurality of shelves I4 adapted to receive cafeteria articles such as sauces, mayonnaise, catsup, butter, cream and the like. The front wall of cabinet I I is also thermally insulated and is provided with a pair of glazed doors I5, I5. Positioned in a vertical plane closely adjacent to and parallel to the rear wall of cabinet II is a water cooling unit I6 comprising a bank of looped piping whose inlet end is connected at I'I through a valve I8 to the municipal water supply main and whose outlet end is connected to a conventional dispensing valve I9 mounted in the lower central portion of the front wall of cabinet I I. Valve I9 is of the conventional type which is actuated 3 Claims. (Cl. Z50-52) by the pressure of a glass thereagainst, said glass being positioned under the outlet spout of the valve.

Positioned in effective heat transfer relationship with cooling coil I6 is a freezing unit 2] containing refrigerant, said freezing unit 26 being connected to a motor driven compressor 2| mounted in a compartment 22 provided at the bottom of cabinet II.`

Extending peripherally around cabinet II between storage compartment I3 and compressor compartment 22 is a space 23, the front portion thereof being closed, cabinet II being formed with a lower forwardly projecting vertical wall portion 24. Mounted in the bottom plane of peripheral space 23 are four conveyor belts, there being a front conveyor belt 25, a right side conveyor belt 26, a rear conveyor belt 2l and a left side conveyor belt 28. The belts 26, 21 and 28 comprise the floor of the space 23 inwardly of the cabinet while the belt 25 comprises a floor forwardly of the front wall of the cabinet and inwardly of the wall 24. The conveyor belts are mechanically coupled together so that they are simultaneously driven by their driving shafts to provide av continuous moving endless surface travelling in a counterclockwise direction around the periphery of cabinet I I, as viewed in Figure 2. It is to be noted that the wall portion 24 extends above the belt 25. The driving mechanism for the belts may be shafts which are coupled together by fiexible shafting, bevel gears, or other suitable power transmission means, the mechanism being actuated by a motor 29 mounted in motor compartment 22 and connected tothe conveyor mechanism by a belt 30. The belts may be of any suitable flexible material such as leather,

chain links, or wire mesh. Motor 29 is controlled by a switch 3| which is located adjacent dispensing valve I9.

Positioned inwardly of and conformably shaped to the vertical Wall portion 24 is aguide plate 32 which is xedly attached to the wall portion 24. 'I'he guide plate 32 has at one corner a curved portion 32a, which serves to guide glasses from the long course or belt 25 onto the short course or belt 28, and another curved portion 32h at the opposite corner which serves to guide glasses from the short course or belt 26 onto the long course or belt 25 in a well known manner, as said glasses are moved forwardly on the belt. At one lend-of the belt 21 there is a guide 32e which serves to guide the glasses from the short course or belt, 28 onto the long course or belt 21, and at the other end of the belt 21 there is also a guide 32d which serves to guide the glasses from the long course or belt 21 onto the short course or belt 26. Each side Wall of cabinet II is formed with an opening 33 through which glasses may be positioned in space 23, each opening 33 being provided with a hinged door 34. Provided at the left front corner of space 23 are a pair of vertically hinged swinging doors 35, 35 which are biased by light springs to a normally closed position but which are adapted to open outwardly by contact of a glass thereagainst as said glass is moved forwardly by belt 28 to thereby allow said glass to be moved onto front belt 25. A similar pair of spring biased normally closed swinging doors 3E, 36 are provided adjacent the left end of belt 25 adapted to open inwardly to allow unused glasses to be returned into peripheral compartment 23 by right side belt 26.

Positioned in the left side portion of peripheral compartment 23 is an ultra-violet ray sterilizing lamp 3? which extends 4substantially the entire length of .said left side portion. Lamp 31 is con.- tinuously energized and emits antiseptic radiation, not only into peripheral compartment 23 but into storage compartment I3 through .an opening 38 in the bottom wall of the storage compartment.

The partition wall between peripheral cornpartment 23 and storage compartment I 3 is perforated at additional locations other than opening 38 to maintain compartment 23 kat substantially the same low temperature as storage compartment I3. I

Positioned beneath conveyor belt 25 and underlying valve I9 is a funnel-shaped drain member 39 which is connected by a drain pipe A0 to a drain receptacle 4I. Drain pipe Q0 is rearwardly oliset to provide clearance for a drawer 42 in which tableware such as knives, forks, .spoons and the like will be stored.

The top of cabinet I I is formed witha shelf 43 for storing extra glasses, pitchers, or other articles when not in use.

In operation glasses are placed in peripheral space 23 through the side door openings 34, said. g

glasses being deposited on the side conveyor belts. When glasses of water are desired. the diners turn switch 3| on causing the belts to operate. This causes the desired number of glasses to emerge through doors 3'5, 35 and to move toward the location of valve I9, When as many glasses as are .needed are available switch 3I is opened, causing the conveyorto stop. Unused-glasses `will return .to peripheral space .23 through right swinging doors 36, 36 4during subsequent operations ofthe conveyor belts.

The cabinet may be mounted on anysuitable support instead of on legs I2 if so desired. Legs I2 may be readily detached for this purpose.

While a specic embodiment of a drinking Waterdispenser has been disclosed in the foregoing description. it will be understood that various modifications within the spirit of the invention may occur to those skilled in .the art. Therefore it is intended that no limitations be placed on the invention other than-as deiined` by the scope of the appended claims.
