IPC: A23G9/10
Filed: 1955-12-13
Abstract: 789,706. Ice making. HOYER, O. G. Dec. 13, 1955 [Dec. 17, 1954], No. 35815/55. Class 29- [Also in Group XXIV] Relates to an ice-cream freezing machine comprising an annular table divided radially into sections, each section having equally spaced radial lines of moulds with the distance between the last line of moulds in one section and-the first line of moulds in the next section being different from the distance between the lines of moulds of a section. Means are provided for imparting a step-by-step motion to the table and a switching mechanism actuated by control members on the freezing table causes variation in the length of step. The embodiment is described as applied to the ice cream freezing machine described in Specification 744,583. The table is moved by a driver 1 having a vertical reciprocating motion and given a horizontal motion by a link 2 in which the driver 1 slides, pinned to a pivoted lever 4. At the lower end of the lever 4 is an arcuate slot 6 in which slides a roller 8 fixed to the end of a link 9 connected by a lever 10 to a rocking shaft 11. The roller 8 normally rests at the bottom of the slot 6 and the rocking movement of the shaft 11 is converted into a relatively short horizontal translation of the driver 1. An arm 14 is pivoted at a point 16 intermediate of its length and has at its free end a roller 17, the other end being linked by a compressible rod 12 to the link 9. Cams 18, fixed to the side of the rotating table, on contacting the roller 17 pivot the arm 14, thus raising the roller 8 in the slot 6 and lengthening the horizontal translation of the driver 1. The travel of roller 8 and thus the length of the horizontal movement of the driver may be limited by adjustable stop members 25, 26.
