UNITED STATES PATENTYOFFICE ALVIN G. SHERMAN, GROBSE POIN'IE, MICHIGAN ICE CUBE FOBMING AND DISI ENSING DEVICE Application filed January 16, 1930. Serial No. 421,184.

This invention relates to an ice cube formvious that the resent invention will vary ing and dispensing device, and has to do parwidely in accor ance with the particular inticularly with novel means, in combination stallation. In the drawings I have shown a with sharp freezing apparatus, for automasomewhat standard design of sharp freezing tically forming and delivering ice cubes. unit of the flooded or brine tank type.

of the cabinet. The relationship between the pawl 11 and the ratchet teeth 10 is preferably such that the container belt is moved a distance to discharge a single cube at a time.

This is accomplishedby providing a shell member 13 which is arcuate in shape and which terminates in a series of stepped edges 14. For instance, if the belt is so arranged as to present four containers in each row as shown in Fig. 3, then the steps which separate the edges 14 are so divided that the width of all the steps equals approximately the width of one container or ice cube. The relationship between said pawl and ratchet is also such that the beltis moved each time only the distance 15 of one step. Of course, it will be obvious that any number of cubes may be dispensed simultaneously if desired, but in the ordinary domestic unit one cube at a time is desirable and hence the present showing.

The ratchet wheel 10 is preferably provided with pins 16 which are spacedin accordance with the number of container in each row of containers. A rod 17 is pivotally mounted at any desired poin say at 18, and the movement of this rod is designed to actuate a measuring valve 19, such valve being constructed to deliver a measured quantity of liquid upon actuation, and in the present case the valve should be of such size as to deliver enough liquid to fill a container 8. A plurality of tubes 20 are preferably provided for delivering the liquid into the separate containers and in this connection either a single or a multiple number of valves 19 may be used.

The pins 16 are preferably so arranged that the rod 17 will be actuated when the containers 8 approach a position substantiallv directly and centrally beneath the conduits 20. If the belt is movedby a step by step movement in accordance with the width of the steps 15 then it will be obvious that the pin 16 will be so positioned that a short movement of each container as it passes centrally below the conduit 20 will be effective to discharge the required amount of liquid into the container or containers.

As the actuating pin 16 is moved on past by further actuation of the member 12, then of course the valve 19 will be returned to normal position so that the required amount of liquid will flow thereinto in the correct measured quantity.

In operation, movement of the member 12 will actuate the container belt sufiiciently to move a cube of ice a distance so it will pass by one of the edges 14. Due to the fact that this cube of ice has been pressed outwardly by one of the projections 9, it will be obvious that it will be discharged into the dispensing chute as it moves past the edge 14. In this connection it will be noted that the shell member 14 is preferably formed of or faced with rubber or similar material to which ice does not readily adhere so that if the belt should stay in one position for any length of tilrnfi the cube of ice will not adhere to such s e 12 will, of course, advance the belt to cischarge a cube of ice each time it is actuated. As a'row of containers 8 approach a position centrally beneath the conduit 20, as best shown in Fig. 1, one of the pins 1 6 will contact with the end of the rod 17 whereby to actuate the measuring valve 19 and discharge a predetermined amount of li uid into each container or containers. As t e belt is advanced under continued use, the liquid in the containers will freeze as the container pass through the freezing zone.

It will be obvious that the supply of ice cubes is preferably unlimited, as not only may the belt be made much wider to accommodate a greater number of containers but it will also be obvious that the belt may be made much longer. I

The entire belt is preferably substantially surrounded by the cooling unit so that the pockets or containers are cooled after dispensing the ice cubes and up until the time the water is injected thereinto. This will rapidly promote the freezing action particularly as contrasted with the present use of ice trays whereby they are materially warmed when the ice is removed therefrom. It will understood that the details of the embodiment illustrated are more or less diagrammatic for the reason that any number of different arrangements could be designed for carrying out substantially the same results.

at I claim is:
