Spiral meat slicer

Claim 1

A spiral meat slicer for forming a continuous spiral slice on a cut of meat having an irregularly shaped bone extending therein comprising means for mounting the meat with the bone as a substantially vertical axis about which to rotate the meat, a vertically movable carriage, a horizontally pivotable support structure pivotably mounted on said carriage, a knife for slicing the meat mounted on said support structure, said knife being positioned with respect to the axis of rotation of the bone to enable a spiral cut to be made in the meat, means for longitudinally reciprocating the knife against the meat, means for rotating the meat, means for relatively moving said carriage vertically with respect to the meat to advance the knife along the axis of rotation of the meat to form a continuous spiral slice in the meat, lever means for moving the knife into slicing engagement with the meat, resilient means interconnecting said lever means with said support structure to yieldingly maintain the knife in contact with the meat bone, a rigid elongated element interconnecting said lever means with said support structure, said rigid element being pivotably connected at one end to one of said lever means and said support structure and slidingly and pivotably connected at the other end to the other of said lever means and said support structure, said sliding connection permitting only limited sliding movement to accomodate variations in bone size, said rigid element including adjustment means to vary the length thereof, said means for relatively moving said carriage vertically with respect to the meat comprising a substantially vertical power driven worm, a freely rotatable worm gear mounted on said carriage in engagement with the worm, said worm having a reduced diameter unthreaded portion proximate the upper end thereof for limiting the extent of upward movement of said carriage after completion of a spiral cut.
