ABSTRACT:
A gel slicer consisting of a support with a gel guide trough and a feed screw journalled parallel to the trough. A feed plunger assembly is threadedly engaged on the feed screw and has a plunger portion slidably engaged in the trough. The feed screw is intermittently driven by a power shaft via selectable identical-diameter gear discs with different-length tooth configuration for varying the increment of feed of the gel per revolution of the power shaft. The gear discs have smooth peripheral portions providing dwell periods of the feed screw. A pivoted transverse cutting blade is spring-biased toward cutting position over the trough and is held elevated by a follower lug engaging a cam on the power shaft, the cam having a blade-release notch. The cam is synchronized to release the cutting blade during the dwell period of the feed screw. Thus, the thickness of the slice depends on the amount of teeth on that gear disc which is selected to drive the feed screw. The selected gear provides desired incremental steps of longitudinal movement of the gel.
