Abstract
A hollow pin set in the downstream end of the auger of a conventional food grinder has a downstream end which protrudes to an accessible outside area of the grinder and a downstream - facing shoulder which bears against the upstream side of the knife assembly of said grinder, biasing said knife against a perforated plate. An inside pin or bolt passes through the hollow pin, threadably connected therewith, and has a downstream end which protrudes from the hollow pin and which is adapted to receive a wrench. The upstream end of said inside pin or bolt presses against a compression spring. Applying a wrench to rotate the downstream end of said inside pin or bolt changes the compression of the spring and thereby increases or decreases the bias between said knife assembly and the perforated plate which the knife is biased against.
