Cutter head for use in meat grinders

Claim 1

A cutter head in a meat-comminuting device, said cutter head having an axis of rotation and comprising individually removable cutter units, each unit including 1. a retaining disc, 2. a clamping disc, a. the discs being coaxially mounted along the axis of rotation and defining therebetween a gap perpendicular to said axis, 3. two coplanar cutter teeth in said gap and extending radially from said axis, the cutter teeth being symmetrical in respect of the axis for balance during rotation and having cutter edges moving in a circular orbit about said axis upon rotation, b. the cutter teeth being clamped between and in contact with the discs, and 4. releasable coupling means on the teeth and one of the discs for respectively holding the teeth clamped between the discs in a selected circular orbit, and for pivotally adjusting the teeth in unison relative to said retaining disc into another selected position wherein the cutter edges move in another selected circular orbit, the coupling means including c. a fixed pivot for pivoting each of said cutter teeth on the retaining disc, the fixed pivots of the two teeth being diametrically opposite each other, and d. a sliding pivot for adjustably sliding each of said cutter teeth in respect of the retaining disc, the sliding pivots of the two teeth being diametrically opposite each other, the four pivots of the two teeth forming a rectangle whereby each tooth may slide along the sliding pivot while being pivoted about the fixed pivot thereof.
