  • Patent number: 4176528
    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.degree. 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.degree.
