ENTSCHWARTUNGSMASCHINE

A bacon skinning machine wherein the knife is movable with reference to the traction wheel by a support having two arms which carry the knife holder. The arms are movable lengthwise and are pivotable by two eccentrics mounted on a shaft which is rotatable by a single lever. The lever can move the support to a position in which the holder and the knife can be detached from the arms, to a position in which the holder automatically conforms its position to the thickness of the rind on a slab of bacon, and a starting position. The arms are biased in a direction to urge the knife toward the periphery of the traction wheel, and such arms engage pivot pins in the machine frame in that position of the support when the holder can be detached from the arms. The holder has extensions which carry roller followers serving a track stationary cams in the frame when the arms are disengaged from the pivot pins and the knife is in a position to select its distance from the traction wheel as a function of the thickness of the rind.
