Definitions

  • the present invention relates to a tool for separating ribs from bel ⁇ lies of slaughtered animals and comprising at least one cutting edge.
  • the tool which is cha ⁇ racterized in that the tool consists of a segment of a substantially tubular element, said segment being limited by a front circular edge extending across an angle at the centre from approximately 0° to ap- proximately 180° and by two substantially rectilinear edges emanating from the circular edge and running at an angle of approximately 0° to approximately 20" in relation to the longitudinal axis of the tubular element, that the tool is made of a resilient material, that at least the central part of the front circular edge is made from a hard pre- ferably knockproof material, that at least the one of the cutting ed ⁇ ges is mounted radially projecting from the outer circumference in a position opposite the front circular edge, and that the cutting edge is directed forward and is mounted at an angle in relation to the lon ⁇ gitudinal axis.
  • the flexible segment sur ⁇ rounds a rib as a cover and when the tool manually or mechanically is guided forward along a rib the segment will be guided along the rib which causes the cutting edge mounted thereon to perform a symmetrical cut of the bone fascia in an effective way.
  • the segment has two inclined rectilinear edges the connection between the rib and the bone fascia is moreover severed all over the part of the rib that faces outward. This causes the ribs to be more satisfactorily separated from the peritoneum that would be the case if only an ordinary knife was used for cutting through the bone fascia.
  • the front circular edge of the segment is positioned in the space between the bone fascia and the rib before the bone fascia is cut open.
  • the front circular edge will usually only extend over a small angle at the centre which causes the front edge to be easily introduced into and guided between the rib and the bone fascia.
  • the marginal front circular edge is made in one piece with the remaining part of the segment through a casted hin ⁇ ge connection. This further ensures the steady engagement of the front edge with the rib. If the tool is provided with a front edge of metal which is fastened in a plastic cover a long durability is obtained just as the front edge may advantageously be provided with a chamfered edge.
  • the invention relates to a method of separating ribs from bellies of slaughtered animals by means of a tool of the above-mentio ⁇ ned type characterized in comprising the steps of guiding the front circular edge between the rib and the bone fascia with the radially orientated edge turned away from the rib, pressing forward the tool manually or mechanically along the rib with the front edge of the seg ⁇ ment abutting the rib, and guiding the tool past the cartilaginous tissue between the rib and the meat.
  • a belly is pre-treated quickly and safely in such a way that the belly appears esthetic and without meat wastage after the subsequent removal of the ribs.
  • Fig. 1 shows a schematic perspective view of a tool according to the invention
  • Fig. 2 shows a view of a further embodiment illustrated in Fig. 1
  • Fig. 3 shows a view of a further embodiment illustrated in Fig. 1
  • Fig. 4 shows a view of a further embodiment illustrated in Fig. 1
  • Fig. 5 shows a view seen from the top side of the embodiment illu ⁇ strated in Fig. 2
  • Fig. 6 shows a sectional view for illustrating an embodiment of a tool with an embedded metal edge and a casted hinge
  • Fig. 7 shows an embodiment of a tool with an embedded, curved metal edge
  • Fig. 8 shows an embodiment of a tool with an embedded straight me- tal edge.
  • Fig. 1 shows a tool 1 ccording to the invention.
  • the front part of the tool is formed of a segment 2 of a substantially tubular element 3 which continues unbroken at the other end of the tool.
  • the segment is limited by a front circular edge 4 and by two substantially rectilinear edges 5.
  • the rectilinear edges run at an angle of approximately 5-20° in relation to a longitudinal axis 6 of the tubular element 3.
  • the tool comprises a substantially triangular plate 7 which is fastened to the segment 2 in any well- known way.
  • the plate 7 is provided with a cutting edge 8 which is lo- cated at an acute angle in such a way that it is directed away from the segment and towards the front edge 4.
  • the cutting edge 8 is loca ⁇ ted a short distance from the front edge 4 as the tool easier can be introduced into and guided between a rib and a bone fascia.
  • the seg- ment is made of a resilient material, preferably plastic.
  • the plate 7 is preferably a metal plate which is fastened to the seg ⁇ ment 2 by embedding webs (not shown) in the plastic material for the securing of the plate 7.
  • the plate 7 can also be made of plastic.
  • As the segment 2 is made of a resilient material it will ea- sily adapt itself to the contour of the rib against which the tool is pressed and thus the inner cavity will deviate from a circle when the tool is used.
  • the tool can also be made with two parallelly loca ⁇ ted plates 7 (not shown).
  • Fig. 2 illustrates an alternative embodiment of a tool 1' which dif ⁇ fers from the tool shown in Fig. 1 by having a projecting fang 9 which is fastened to the front circular edge 4.
  • a fang 9 appears more clearly from Figs. 5 and 6.
  • a hard metal apex 14 is used as illu ⁇ strated in Fig. 6, the cartilaginous tissue between a rib and the meat can advantageously be partially cut off of by means of the tool, which facilitates the severance of the cartilaginous tissue.
  • the embodiment of the tool 1" illustrated in Fig. 3 differs from the embodiment shown in Fig. 1 in comprising only the front segment 2 which is limited by the two rectilinear edges 5 and the front circular edge 4. Thus, this tool does not comprise a tubular part.
  • the front edge 4 is chamfered to allow an easier penetration between a rib and a bone fas ⁇ cia.
  • the front edge of the fang 9 is also chamfered.
  • Fig. 4 illustrates an embodiment of a tool 1"' comprising an inner segment 2' of plastic and an outer segment 10 of metal.
  • the outer segment has a smaller extension than the inner segment so that the elastic resilient inner segment more readily adapts itself to the contour of a rib.
  • the pla ⁇ te 7 is advantageously fastened releasably to the outer segment 10.
  • the plate 7 can be replaced when the edge 8 has become blunt.
  • the metallic outer segment has a front narrow fang 11 extending across a very small angle at the centre of approximately 5 ⁇ and which is chamfered to allow penetration between a rib and the fascia.
  • the fang 11 is preferably projecting forward over the front edge 4 of the seg ⁇ ment 2'.
  • Fig. 5 shows how the segment 2 is provided with a fang 9 which is con ⁇ nected with the front edge 4.
  • Fig. 6 shows a sectional view through an embodiment comprising a fang 9 corresponding to the one shown in fig. 4.
  • the fang 9 is connected with the front edge 4 of the plastic segment 2' through a casted hinge 13.
  • the hinge 13 makes it easy for the fang 9 to follow the surface of a rib.
  • the metal apex 14 is connected with the fang 9 by embedment of a part 12 in the plas- tic material.
  • the embedded part may have any suitable form which is used in the art.
  • Fig. 7 illustrates an embodiment in which the tool comprises a solid part 14 used for the fastening of the tool in a stand and in which the plate 7 constitutes a forward extension of the solid part.
  • the edge 8 is curved for forming a substantially semicircular periphery which faces forward in the work direction.
  • the segment 2 is a relatively hard plastic and the front edge 4 is chamfered.
  • the plate 7 is advan ⁇ tageously of metal and is fastened to a fin 15 by casting in the plas- tic of which the fin is made.
  • the fin 15 constitutes an element of the solid part 14, said element being directed forward.
  • the segment 2 is embedded together with the fin.
  • the rectilinear edge 5 extends across an angle of 0° in re ⁇ lation to the longitudinal axis 6 of the segment 2. This angle can al- ternatively be changed and can be up to approximately 20°.
  • Fig. 8 shows an embodiment corresponding substantially to the one shown in Fig. 7, but having a rectilinear edge 8.
  • the plate 7 is also fastened to the fin 15 which constitutes an element of the solid part.
  • the cutting edge 8 extends from near the front chamfered edge 4 and slanting to the rear.
  • the casting of the plate 7 can be performed in any way which ensures a sufficient fasten- ing of the plate 7 in the fin 15.
  • the plate 7 for the casting can be fastened in other ways thus, if necessary, the plate can be replace.
  • Figs. 7 and 8 can be provided with fangs 9 as described in connection with Fig. 6.
  • an effective severance of the bone fascia is obtained as the segment 2 first is introduced between the rib and the bone fascia and is guided inside the bone fascia as this has not yet been cut up.
  • an edge 8 is located which cut up the bone fascia.
  • the edge 8 can be located axially in front of the front edge 4.
  • the front edge 4 separates the connection between the rib and the bone fascia over a substantial part of the circumference of the ribs which contributes to allow the rib to be removed subsequently without the bone fascia being torn up and with ⁇ out a simultaneous removal of the meat.
  • the tool and the method can also be used in connection with the separation of other bones, for instance legs of pork.

Abstract

Instrument (1) permettant de séparer rapidement et avec efficacité les côtes de la carcasse de l'animal, comprenant un segment (2) consistant en un élément sensiblement tubulaire (3). Ledit segment (2) comporte un bord avant circulaire (4) et deux bords rectilignes (5) s'étendant à un certain angle par rapport à l'axe central (6) du segment tubulaire (3). La circonférence externe du segment (2) comprend une plaque (7) ayant un bord coupant dirigé vers l'extérieur et l'avant, en direction du bord avant circulaire (4). Lorsqu'on introduit le bord avant (4) de l'instrument (1) entre une côte et le fascia de l'os, l'instrument suit le fascia non brisé de l'os, et lorsqu'on pousse l'instrument vers l'avant, le bord (8) coupera le fascia de l'os tandis que le bord avant (4) séparera le fascia sur une bonne partie de la circonférence des côtes. On peut ainsi enlever ensuite la côte sans risquer d'inclure le fascia de l'os ou d'enlever simultanément de la viande adhérant à la côte.
