The invention relates to an overhead conveyor for poultry, for example chickens, having a conveyor line, and along the conveyor line movable hooks suspended therefrom with holders for the ends of the poultry's legs. The hooks are rotatable about a substantially vertical axis for the selective adjustment of a direction of movement of the poultry. Each hook is provided at the top with an adjusting plate with cams. Guide members are arranged along the conveyor line and are designed to intermate with the cams, wherein the adjusting plate is provided with at least a first type of cam having a predetermined first length and one or several cams of a second type having a predetermined second length. The first length is smaller than the second length, and the guide members are arranged such that the first type of cam is able to pass a guide member without intermating and the second type of cam is able to pass the guide member only by intermating. The hook can pivot in relation to the adjusting plate about a substantially horizontal axis. Between the adjusting plate and the holders for the ends of the poultry's legs, a catch member is provided for moving said hook out of a vertically suspended position.

The invention claimed is: 1. An overhead conveyor apparatus for processing poultry, comprising: a conveyor line having movable hooks suspended therefrom with holders for the poultry's legs, said hooks rotatable about a substantially vertical axis for adjustment of the suspended poultry; an adjusting plate configured with each said hook, said adjusting plate further comprising first cam members having a first engaging length, and a second cam members having a second engaging length that is greater than said first engaging length; guide members disposed along said conveyor line to engage with said second type of cam causing rotation of said adjusting plate and respective hook, said guide members having a configuration and disposed such that said first cam members pass said guide members without engaging therewith; said hooks pivotal relative to said respective adjusting plates about a substantially horizontal axis; and a catch member configured on each said hook between said holders and said adjusting plate, said catch member engageable by a guide disposed relative to said conveyor line causing said hook to pivot about said horizontal axis out of its vertically suspended position. 2. The apparatus as in claim 1, wherein said guide members are disposed in pairs of first and second guide members, each said pair of guide members spaced along said conveyor line such that each said pair of guide members rotates said hooks about 90 degrees. 3. The apparatus as in claim 2, wherein said first guide members are disposed before said second guide members in a conveying direction of said conveying line. 4. The apparatus as in claim 3, wherein said second guide members have a configuration and are disposed so as to only engage with said second cam members that have been engaged and moved by said first guide members. 5. The apparatus as in claim 4, wherein said first guide members are adjustable between an operational position wherein said first guide members engage said second cam members, and an in operational position wherein said second cam members pass by without engaging said first guide members. 6. The apparatus as in claim 1, wherein said hook pivots relative to said adjusting plate by way of a hinge that is rotationally fixed relative to said adjusting plate, and further comprising a supporting surface disposed around said hinge and disposed against a spring loaded bushing, said bushing rotatable with said hook and further comprising a first groove configured to engage a first fixed pin and define a first position of said hook relative to said conveying line. 7. The apparatus as in claim 6, wherein said bushing is movable in a substantially vertical direction and comprises a non-rotatable shaft and a second pin that engages in a second groove upon vertical upward movement of said bushing, said supporting surface comprising an eccentric course such that when said hook pivots, said spring loaded bushing is caused to move from a first position wherein said second pin is moved out of said second groove to a second position wherein said second pin is moved into said second groove. 8. The apparatus as in claim 7, wherein in said first position of said bushing, said hook is in a suspended substantially vertical position, and in said second position of said bushing, said hook is pivoted laterally out of its suspended vertical position.
