  • Patent number: 8919234
    Abstract: A food slicer includes a frame for supporting a landing and a runway movable relative to the landing. A cutting blade is secured on an upstream end of the landing. A downstream end of the runway is spaced from an edge of the cutting blade. A separate cutting knife is moveably connected to the frame. An adjustment mechanism connected to the frame adjusts an offset between the cutting blade and the runway. The adjustment mechanism includes spaced apart first and second guide tracks provided on respective first and second movable side members. The guide tracks are configured such that a first movement of the adjustment mechanism moves the downstream end of the runway relative to the cutting blade to adjust a cutting thickness and a second movement of the adjustment mechanism lowers the downstream end of the runway and raises the cutting knife to a working position.

  • Patent number: 8438961
    Abstract: In order to set the cutting thickness in kitchen slicers, it is a known procedure to arrange a feed plate at a slant relative to the blade. As an alternative, solutions are known according to which the feed plates are changed so that a suitable feed plate is provided for each cutting thickness that can be set. The objective of the invention is to provide a simple alternative. Towards this end, the invention proposes that the feed plate (11) can be moved surface-parallel to a fixed plate (12) that is connected to the blade (13). This movement can be effectuated by means of a combination of vertical and horizontal movements of the feed plate and of a positioning slide (14) associated with said feed plate.

The hold down bar is free to drop down to act as a safety barrier when no wood panel is present. Then, initial lifting of the hold down bar by a wood panel is initially against the relatively light downward bias of the first coil spring until the sleeve is lifted to a “hold down height” at a point sufficient to compress the first coil spring within the sleeve.
