Abstract

A conveyor belt for use in an ice body maker adapted to transfer the formed ice bodies from a collecting space to a dispensing space. The conveyor belt is arranged to pick up the ice bodies temporarily stored in the collecting space and drop them into a suitable guide chute leading to an upper portion of the dispensing space so that a receiver disposed in the dispensing space may receive the desired qauantity of ice bodies for subsequent disposition as desired. The belt is formed of a plurality of link plates articulated by cooperating knuckles with each plate having a forward edge provided with upstanding cleats and a rearward edge provided with upstanding cleats. The cleats on the forward edge extend at an angle of less than 90° to the plane of the plate and the cleats on the rearward edge may extend at a greater angle to the plane of the plates. In the illustrated embodiment, the forward cleats extend at an angle of approximately 60° to the plate and the rearward cleats extend at an angle of approximately 90° to the plate. The belt may be entrained about upper and lower sprockets so as to extend at an upwardly forwardly directed angle so that the ice bodies picked up by the cleats are caused to be discharged into the dispensing space as a result of the cooperative functioning of the cleats and the flat surface of the link plates. The plates may be connected by hinges including open knuckles on the front and rear edges of the plates for facilitated maintenance and assembly.

Claims

1. In an ice body maker having means defining an ice body collecting space, means for making ice bodies and delivering the ice bodies to said collecting space, and means defining an ice body dispensing space adapted to receive a removable ice body receiver, the improvement comprising:

a continuous flexible belt defined by a plurality of link plates articulated by cooperating knuckles and each having a front edge and a rear edge, first ice body engaging cleats at said front edge extending forwardly at an angle of less than 90°

to the plane of the plate, and second ice body engaging cleats at said rear edge and extending at an angle to the plane of said link plate greater than the angle of said first cleats to the plane of the plate; and

means for driving the belt in an upright loop having a lower end disposed in said collecting space and an upper end disposed superjacent said dispensing space, the second cleats of each preceding link plate being disposed in interdigitated alignment with the first cleats of the following link plate whereby ice bodies are picked up on said first and second cleats as the belt moves upwardly through said collecting space, the ice bodies picked up on said second cleats sliding forwardly therefrom over the link plate to fall over the front edge of the link plate substantially directly into said dispensing space when the link plate reaches said upper end of the upright loop and the ice bodies picked up on said first cleats sliding forwardly therefrom over the preceding link plate to fall against the back of the first cleats of the preceding link plate and be deflected thereby into said dispensing space when the link plate moves to and slightly beyond said upper end of the upright loop.

2. The ice body maker of claim 1 wherein said first cleats extend at an angle of approximately 60°

to the plane of said plate.

3. The ice body maker of claim 1 wherein said second cleats extend substantially perpendicularly to the plane of said plate.

4. The ice body maker of claim 1 wherein said cleats are spaced apart along the front and rear edges of said plate.

5. The ice body maker of claim 1 wherein said cleats are spaced apart along the front and rear edges of said plate, said first cleats being aligned with the spaces between said second cleats and said second cleats being aligned with the spaces between said first cleats.

6. The ice body maker of claim 1 wherein said means for driving the belt includes upper and lower sprockets, each having a polygonal plate engaging periphery, each face of said periphery having a length substantially equal to that of said link plates.

7. The body maker of claim 1 wherein said means for driving the belt includes upper and lower sprockets, said upper sprocket being displaced forwardly above said lower sprocket whereby said loop is inclined upwardly forwardly at an angle to the vertical from said lower end to said upper end.

8. The ice body maker of claim 1 wherein said means for driving the belt includes upper and lower sprockets, said upper sprocket being displaced forwardly above said lower sprocket whereby said loop is inclined upwardly forwardly at an angle of approximately 60°

to the vertical from said lower end to said upper end.

9. The ice body maker of claim 1 wherein said means for driving the belt includes upper and lower sprockets, said upper sprocket being displaced forwardly above said lower sprocket whereby said loop is inclined upwardly forwardly at an angle similar to the angle of said first cleats to the plate.

10. The ice body maker of claim 1 wherein said belt includes an odd number of link plates.

11. The ice body maker of claim 1 wherein said link plates are formed of 1/4 hard stainless steel.

12. The ice body maker of claim 1 wherein said link plates define open knuckle hinge elements on said front and rear edges, and removable pins interconnecting said elements of successive ones of the link plates providing facilitated assembly and maintenance of said belt.

13. In wall means defining an ice body collecting space, the improvement comprising:

a continuous flexible belt defined by a plurality of link plates articulatd by cooperating knuckles and each having a front edge and a rear edge, first ice body engaging cleats at said front edge extending forwardly at an angle of less than 90°

to the plane of the plate, and second ice body engaging cleats at said rear edge and extending at an angle to the plane of said link plate greater than the angle of said first cleats to the plane of the plate; and

means for driving the belt in an upright loop having a lower end disposed in said collecting space and an upper end disposed for delivery of ice bodies to an adjacent ice body dispensing space, the second cleats of each preceding link plate being disposed in interdigitated alignment with the first cleats of the following link plate whereby ice bodies are picked up on said first and second cleats as the belt moves upwardly through said collecting space, the ice bodies picked up on said second cleats sliding forwardly therefrom over the link plate to fall over the front edge of the link plate substantially directly into said dispensing space when the link plate reaches said upper end of the upright loop and the ice bodies picked up on said first cleats sliding forwardly therefrom over the preceding link plate to fall against the back of the first cleats of the preceding link plate and be deflected thereby into said dispensing space when the link plate moves to and slightly beyond said upper end of the upright loop.
