Method and an apparatus for cleaving slaughtered carcasses

Claim 2

An improved method of cleaving slaughtered carcasses, the cleaving operation taking place essentially centrally by sawing through the spine while pulling the carcass forward lying on the back, the improvement consisting in that the two halves of the carcass obtained from the cleaving operation are moved apart and guided in such a way that the lower portion of each half is tipped inwardly while its upper portion is moved outwardly in order that the spine portion remaining in each carcass half may be pressed outwardly on the inside of the carcass half and become accessible for cutting by means of a saw while removing the smallest possible quantity of adjacent muscles above and below the spine portion.

Claim 3

Improved apparatus for cleaving slaughtered carcasses comprising a table for carrying the carcass lying on its back, a circular saw projecting upwardly from the table and means for pulling the carcass on the table forward during the sawing operation; the improvement consisting in that there is a guiding body disposed symmetrically on both sides of the circular saw on the table for guiding the halves of the carcass obtained through the cleaving operation by means of said circular saw centrally through the spine, while moving said two halves apart; in that there being provided in the said guiding body on the outside thereof, between guiding surfaces disposed obliquely in relation to each other a channel for receiving the spine portion remaining in each carcass half over at least part of its length; and in that there are provided saw means immediately after the channel in the guiding body for cutting off the spine portion on each half of the carcass guided by means of said channel.

Claim 4

Improved apparatus for cleaving slaughtered carcasses comprising a table for carrying the carcass lying on its back, a circular saw projecting upwardly from the table and means for pulling the carcass on the table forward during the sawing operation; the improvement consisting in that there is a guiding body disposed symmetrically on both sides of the circular saw on the table for guiding the halves of the carcass obtained through the cleaving operation by means of said circular saw centrally through the spine, while moving said two halves apart; in that there being provided in the said guiding body on the outside thereof, between guiding surfaces disposed obliquely in relation to each other a channel for receiving the spine portion remaining in each carcass half over at least part of its length; and in that there are provided saw means immediately after the channel in the guiding body for cutting off the spine portion on each half of the carcass guided by means of said channel.

Claim 5

Apparatus as claimed in claim 2, wherein the said saw means consists of a pair of circular saws adjustable in the vertical sense.

Claim 6

Apparatus as claimed in claim 2, wherein there are spring loaded means for pressing the carcass halves against the guiding body on both sides of the guide body.

Claim 7

Apparatus as claimed in any one of claims 2, wherein there is provided above the guiding body a second upper guiding body which extends in front of the circular saw with a plough-like portion for engagement with the belly side of the carcass after it has been cut open and the offal removed, before and after the cleaving thereof essentially centrally through the spine and for guiding the carcass during its movement past the circular saw.

Claim 8

Apparatus as claimed in claim 5, wherein the upper guiding body has a pair of swingable legs in the area of its plough-share which may be introduced into the carcass and which are yielding against spring action in the intended direction of movement of the carcass.

Claim 9

Apparatus as claimed in claim 5 having a fender projecting above the table for guiding the carcass while tipping it from a suspended position to a horizontal position on the table, wherein there is provided a guiding slot in the said fender, said guiding slot being connected at its lower end with the plough-share of the upper guiding body and being arranged in such a way as to receive the tail of the carcass guidingly during the movement of the carcass along the fender.

Claim 10

Apparatus as claimed in claim 7, wherein the guiding slot has a flaring entry opening in its upper end.

Claim 11

Apparatus as claimed in claim 8, wherein there is provided on the fender a spring bar extending inwardly between the cut-apart thighs and guiding the tail of the carcass into the flared entry opening of the guiding slot.

Claim 12

Improved apparatus for cleaving slaughtered carcasses, comprising a table for carrying the carcass lying on its back, a circular saw projecting upwardly from the table and means for pulling the carcass on the table forward during the sawing operation; the improvement consisting in that there is a guiding body disposed symmetrically on both sides of the circular saw on the table for guiding the halves of the carcass obtained through the cleaving operation by means of said circular saw centrally through the spine, while moving said two halves apart; in that there being provided in the said guiding body on the outside thereof, between guiding surfaces disposed obliquely in relation to each other a channel for receiving the spine portion remaining in each carcass half over at least part of its length; and in that at the entry side of the apparatus there being provided means for removing front teeth and canine teeth of the head of the carcass.

Claim 13

Improved apparatus for cleaving slaughtered carcasses, comprising a table for carrying the carcass lying on its back, a circular saw projecting upwardly from the table and means for pulling the carcass on the table forward during the sawing operation; the improvement consisting in that there is a guiding body disposed symmetrically on both sides of the circular saw on the table for guiding the halves of the carcass obtained through the cleaving operation by means of said circular saw centrally through the spine, while moving said two halves apart; in that there being provided in the said guiding body on the outside thereof, between guiding surfaces disposed obliquely in relation to each other a channel for receiving the spine portion remaining in each carcass half over at least part of its length; and in that at the entry side of the apparatus there being provided means for removing front teeth and canine teeth of the head of the carcass.

Claim 14

Apparatus as claimed in claim 10, wherein said teeth removing means comprises a nipping means arranged on a rocker, said nipping means being activated when said rocker is rotated.
