  • Patent number: 4467708
    Abstract: The present invention is a stripping apparatus for a machine that provides a filling in the interior of an article, such as a cake, continuously conveyed through the machine. The machine includes a filling manifold to which filling needles are rigidly attached. The filling manifold is raised and lowered to inject the needles into and retract them from the articles while moving synchronously with the articles. The stripping apparatus substantially prevents relative lateral movement between the articles and stripper bars that contact the articles. The stripping apparatus includes a stripper frame, carrying the stripper bars, that is slidably mounted to the machine frame by slide blocks. Scissors-links that link the slide blocks to the filling manifold synchronize the movement of the stripper bars with the movement of the filling manifold.

  • Patent number: 4370921
    Abstract: The present invention involves a doughnut fryer guide to guide advancing dough forms through the hot oil bath in a doughnut frying machine. The doughnut fryer guide comprises a rack that supports a plurality of guide bars that limit movement of the advancing dough forms transverse to the direction of advance when the guide bars are in an operative position. Retracting means are provided for raising and lowering the rack to move the guide bars between a retracted and an operative position. In the retracted position the guide bars do not interfere with the dough forms advancing through the oil bath.
