The Flywheel slicer U.S. Berkel model 150 S was built in the period from 1925 to 1935 at La Porte in the state of Indiana. This model has a blade of 350 mm. and 370 mm. of diameter depending on the period of production that is fixed on the shoulder where we also find the apparatus for sharpening the blade very characteristic of rounded shape and completely nickel-plated at the beginning of production, which is then replaced by a more modern version also adopted on other models. In the lower part of the shoulder we find a round plate that depicts the face of W.A. Berkel and indicates the manufacturing factory. By removing the fastening screws of the plate you can access a slot that allows you to see the screw for adjusting the chain tension and to intervene. The machine has a regulation of the thickness of the slice with 24 positions placed in the right side of the cart, which through a lever gives the possibility to adjust the progress of the plate. It is equipped with an automatic system for transporting the cut product directly onto a support surface that automatically drops to each cut slice. On the left side, fixed on the body of the machine we find the metal glove where the cut goods are placed. The movement of the trolley is carried out by means of three connecting rods, of which the third which is smaller than the second fixed on the trolley is connected to a cam which is located on the right side of the carriage and with a whirling movement moves the arms that perform the movement of the sprinkler on the gear fixed on the worm screw. The worm is of the six-principle type.
