Abstract
Abstract A device for cutting slaughtered poultry in separate pieces. A bird is held by at least one radial processing device which is movable on a frame by a driving device which is provided with a processing arm, at the side facing the frame being provided with an adjustment mechanism which can reorient the processing device during the movement of the arm in a number of various positions of rotation with respect to the arm and a blocking mechanism which can fix the processing device in said positions of rotation, with a deblocking mechanism for unlocking the processing device, and said processing arm at the side facing away from the frame being provided with a stretching mechanism for holding the bird. A number of driven knives mounted on the frame comprise of a first knife for cutting the breast, a second knife for cutting the first wing, a third knife for cutting the bird lengthwise in two halves, a fourth knife for cutting the other wing, a fifth knife for cutting the entire leg and a sixth knife for cutting the lower legs from the rumps.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
158 words
An apparatus for cutting slaughtered poultry into separate pieces, comprising, a frame, a plurality of cutting stations which are spaced apart, a holding means for holding a bird, said holding means being supported on the frame and being movable in a machine direction to carry a bird successively through said cutting stations, said holding means being rotatable to change the orientation of a bird thereon with respect to the machine direction, drive means for moving the holding means in said machine direction to carry the holding means through said cutting stations, reorientation means operable while the holding means is located between successive cutting stations for unblocking the holding means to permit rotation thereof, rotating the holding means to a different orientation, and blocking the holding means to retain it at said different orientation relative to the machine direction, each of said cutting stations having a driven knife positioned in the path of a bird on said holding means.
Claim 2
Independent Claim
158 words
An apparatus for cutting slaughtered poultry into separate pieces, comprising, a frame, a plurality of cutting stations which are spaced apart, a holding means for holding a bird, said holding means being supported on the frame and being movable in a machine direction to carry a bird successively through said cutting stations, said holding means being rotatable to change the orientation of a bird thereon with respect to the machine direction, drive means for moving the holding means in said machine direction to carry the holding means through said cutting stations, reorientation means operable while the holding means is located between successive cutting stations for unblocking the holding means to permit rotation thereof, rotating the holding means to a different orientation, and blocking the holding means to retain it at said different orientation relative to the machine direction, each of said cutting stations having a driven knife positioned in the path of a bird on said holding means.
Claim 3
Dependent Claim
75 words
An apparatus according to claim 1 wherein the reorientation means is operable to place a bird at an orientation where said knife at one cutting station cuts the breast, a knife at another cutting station cuts the bird lengthwise into two halves, a knife at another cutting station cuts a second wing, a knife at another cutting station cuts the legs, and a knife at another cutting station cuts the lower legs from the rumps.
Claim 4
Dependent Claim
125 words
An apparatus according to claim 1 wherein said reorientation means comprises the following: an adjusting and blocking disc which is connected to and rotatable with said holding means, said adjusting and blocking disc having a plurality of holes and a plurality of adjusting pins, a blocking pin which is movable in the machine direction with the holding means, said blocking pin being movable between an engaged position and a retracted position where it is respectively engaged and retracted from one of the holes in said disc, a plurality of deblocking cam means affixed to the frame for moving said locking pin to its retracted position, a plurality of adjusting cam means affixed to the frame for engaging said adjusting pins to rotate said holding means.
Claim 5
Dependent Claim
61 words
An apparatus according to claim 1 wherein the holding means comprises the following: a support member, means for engaging the legs of the bird to hang the bird in front of the support member, means for holding the wings of the bird, and means for holding the body of the bird at a fixed orientation in front of the support member.
Claim 6
Dependent Claim
163 words
An apparatus according to claim 1 wherein the holding means comprises the following: a base member, a back support for the body of the bird, said back support being mounted at the front of the base member, a pair of levers pivotally mounted on an upper portion of the base member and having forward ends provided with U-shaped suspension hooks for engaging the knee joints of the bird, said levers having rear ends connected to the base member by tension springs, a pair of pivoted support arm provided with means for engaging the body of the bird, a pair of pivoted wing clamps for holding the wings of a bird and a cam plate slidably mounted on the base member, said cam plate having recesses engaged with the support arms for moving the support arms in response to sliding movement of the cam plate, said cam plate having cams for moving the wing clamps in response to sliding movement of the cam plate.
Claim 7
Dependent Claim
47 words
An apparatus according to claim 5 wherein two said support arms are provided with retaining plates located to project inwardly to engage the rump of the bird, and two said support arms are provided with transverse plate-like grippers located to engage behind the backbone of the bird.
Claim 8
Dependent Claim
28 words
An apparatus according to claim 6 wherein said retaining plates are adjustably supported on the support arms for movement in planes which are perpendicular to the support arms.
Claim 9
Dependent Claim
21 words
An apparatus according to claim 5 having wing hooks affixed to the base member in the vicinity of the wing clamps.
Claim 10
Dependent Claim
47 words
An apparatus according to claim 8 wherein two said support arms are provided with retaining plates located to project inwardly to engage the rump of the bird, and two said support arms are provided with transverse plate-like grippers located to engage behind the backbone of the bird.
Claim 11
Dependent Claim
28 words
An apparatus according to claim 9 wherein said retaining plates are adjustably supported on the support arms for movement in planes which are perpendicular to the support arms.
Claim 12
Dependent Claim
117 words
An apparatus according to claim 5 having a shaft which is pivotally mounted on the frame and is connected to the support arms, a rod which is slidable on the base member and is connected to the cam plate, said rod having a cam follower at one end for engaging a rising cam on the frame, a locking lever pivotally mounted on the base member and having means for holding said rod and the cam plate at a given position when a bird is on the holding means, an unlocking cam affixed to the frame for disengaging said locking lever from said rod to permit movement of the rod and the cam plate from said given position.
Claim 13
Dependent Claim
47 words
