Abstract
Abstract A device for cleaving carcasses of slaughtered animals, consisting of a sword-like tool carrying out chopping, cleaving strokes along the middle plane of the backbone of the carcass, the cleaving tool being, through a servo controller, guided by a pair of castors following either side of the backbone so as to move along the middle plane of said backbone even when same is more or less distorted.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
189 words
In a device for cleaving of carcasses of slaughtered animals, especially pig carcasses, by chopping, cleaving strokes with a sword like tool which parts the carcass, after the belly having been cut open in its longitudinal direction and the entrails having been removed, in two symmetrically equal halves, by which the backbone of the carcass is cleaved in the longitudinal direction, which tool is fixed to and protrudes from one end of the housing which comprises power transferring means which applies chopping movements to the tool and which thereby is moved downwardly along a vertical post, the carcass being supported by a stand which keeps the carcass in vertical position during the cleaving operation, the improvement comprising: the housing carrying a pair of free rotating casters which are arranged for contacting each side of the inner side of the backbone of the carcass tO follow same, and a servo controller coupled to said casters to bring the tool to move along the middle plane of the backbone which coincides with the distorted parting plane by turning said cutting tool about a horizontal axis which substantially coincides with its edge.

Claim 3
Dependent Claim
68 words
The device as claimed in claim 1, in which the servo controller also serves to keep the pair of casters in engagement with the backbone with a certain pressure, the casters being wedge-shaped so that they may be influenced by the backbone axis-parallelly as well as radially so as to be able to transfer to the servo control components of control impulses in right angle to each other.
Claim 4
Dependent Claim
44 words
The device as claimed in claim 1, including a stretching means consisting of a gripping means which grips and retains the nose of the carcass, and a pneumatic or hydraulic cylinder which, via the gripping means, keeps the carcass stretched during the cleaving operation.
Claim 5
Dependent Claim
32 words
The device as claimed in claim 3, in which a plate against which the nose of the carcass is moved by the stretching means, stops said movement simultaneously starts the cleaving operation.
