Apparatus for a slaughterhouse, more specially for the removal of the toe-web of pigs
| Details |
Inventors: Dreves, Adrianus;
Assignee: North West Engineering B.V. (NL)
Primary Examiner: Abercrombie; Willie G.

Attorney, Agent or Firm: Allegretti, Newitt, Witcoff & McAndrews
An apparatus for use in pig-slaughterhouses for the removal of the toe-web between the toes of the hindlegs of a slaughtered pig. The bodies of slaughtered pigs, vertically hung on carrying-yokes, are carried by a conveyer. The bodies are oriented by a spring-loaded yoke so that they will pass through a removing-station with the hindlegs perpendicular to the direction of transportation. A double swing is placed on each side of a rotating milling-cutter (of the metal-milling type). The swing allows the milling-cutter to rotate in a plane parallel to the direction of transportation. The milling-cutter also positions itself with an elongate guide into the right position for each subsequently arriving and passing pair of hind-legs. |

DETAILED DESCRIPTION What is claimed is: 1.
An apparatus for the removal of a toe-web from the hindleg of a slaughtered pig, said slaughtered pig having been hung with the tendons of said hindleg on a coat-hook-shaped carrying-yoke, the latter being pivotable about a vertical axis, being hung on a horizontal conveyor, and being uniformly moved forward, said conveyor including a carrying structure and said carrying-yoke for passing along a toe-web cutting station, comprising, in combination: a rotatable driven-milling-cutter having a cutting wheel adapted for cutting said toe web; an orientation-means, fitted on the carrying structure of the conveyor, which, over a limited trajectory of the conveyor path in the area of the toe-web cutting station, orients the vertically hanging body on its carrying-yoke with respect to the direction of transportation by pivoting said vertically hanging body about the vertical rotation axis of the yoke, and maintaining a line connecting both hindlegs perpendicular to the conveyor path during the removal of the toe-web; supporting means for rotatingly supporting said cutting wheel while the axis of rotation of the cutting wheel is continuously maintained in a vertical plane perpendicular to the conveyor path, said supporting means being pivotable about at least one axis parallel to the direction of transportation; and guiding means, fitted on said supporting means, for self-orientation of said cutting wheel in relation to the hindleg of the pig.
2.
An apparatus according to claim 1 characterized wherein said orientation means includes a pivotable, turned-over U-shaped orientation-yoke, which is pivotably supported with the base of its U-shape about a horizontal pivoting shaft perpendicular with respect to the conveyor path and which bears, each leg having a free end, and wherein said orientation-means includes resilient means, interconnected between said legs of said carrying-yoke and said carrying structure, for urging the orientation-yoke against the carrying-yoke, whereby the orientation-yoke passes through the milling station in one and the same orientation perpendicular to the direction of transportation
