## Abstract

A deboner for a poultry part equipped with a first jaw and a second jaw mounted on an up-and-down movable slide block supporting a first frame portion, a second frame portion, and a third frame portion. The first jaw and the second jaw are movable towards and away from each other, wherein the first jaw is through a first hinge connected with the first frame portion so as to enable a rotational movement of the first jaw with respect to the first frame portion. A second hinge pivotably connecting the first frame portion to the third frame portion and a third hinge pivotably connecting the second frame portion with the third frame portion share a common axis of rotation.

## Claims

### Claim 1

A deboner for a poultry part, wherein the poultry part to be processed is suspended in a conveyor for moving the poultry part along the deboner to enable processing the poultry part by the deboner, the deboner comprising,
a first jaw and a second jaw that are arranged to engage the poultry part;
an up-and-down movable slide block supporting a first frame portion, a second frame portion, and a third frame portion, wherein the first jaw and second jaw are mounted on the slide block, wherein the first frame portion is rotatably mounted on the third frame portion, and the second frame portion is rotatably mounted on the third frame portion, and wherein the first jaw and the second jaw are movable towards and away from each other;
a first hinge connecting the first jaw and first frame portion so as to enable a rotational movement of the first jaw with respect to the first frame portion;
a second hinge that pivotably connects the first frame portion to the third frame portion; and
a third hinge that pivotably connects the second frame portion with the third frame portion, wherein the second hinge and third hinge share a common axis of rotation.

### Claim 2 (depends on 1)

The deboner of claim 1, wherein the conveyor includes a series of carriers for suspending the poultry part, and wherein the common axis of rotation and one of the carriers from which the poultry part is suspended are exactly vertically aligned with each other.

### Claim 3 (depends on 1)

The deboner of claim 1, further comprising a fourth hinge connecting the second jaw with the second frame portion so as to enable a rotational movement of the second jaw with respect to the second portion so that both the first jaw and the second jaw can adjust to a dimension of the poultry part.

### Claim 4 (depends on 1)

The deboner of claim 1, wherein at least one of the first jaw and the second jaw is spring-loaded so as to urge the concerning jaw in use towards the poultry part and enable that such jaw passes any knuckle present in the suspended poultry part.

### Claim 5 (depends on 1)

The deboner of claim 1, wherein the first jaw and the second jaw are both individually spring-loaded so as to individually urge both the first jaw and the second jaw in use towards the poultry part and enable such jaws to pass any knuckle present in the suspended poultry part.

### Claim 6 (depends on 1)

The deboner of claim 1, where the first frame portion is connected to a first actuator for executing a rotational movement of the first frame portion with respect to the third frame portion.

### Claim 7 (depends on 6)

The deboner according to claim 6, wherein the second frame portion is connected to a second actuator for executing a rotational movement of the second frame portion with respect to the third frame portion.

### Claim 8 (depends on 1)

The deboner according to claim 1, wherein the slide block is provided with a first guide wheel, wherein the first actuator, the second actuator, or both, are connected to another slide block provided with a second guide wheel, both guide wheels being equipped to cooperate with guide tracks provided at a carousel-drum's circumference such that the slide blocks' altitude is determined by the guide tracks of the carousel-drum.

### Claim 9 (depends on 1)

A processing line, comprising:
a conveyor with carriers for suspending poultry parts; and
a deboner according to claim 1.
