~' ,; BACKGROUND OF THE INVENTION
i. j 1. Field of the Invention , This invention relates to a device for boning (dlssociating meat from) poultry wings that are naturally equipped with ulna and radius as bones.
2. Description of the Prior Art ~ .
As a consequence of the naturally complicated structure of chicken, duck or other poultry wings that have two thin bones, namely ulna and radius, there has so far been no device for mechanically dissociating the wing meat from the two interconnected bones in a satisfactory way. These two ~,~1 bones are not used by the final consumer and are therefore of great disadvantage to the sale of meat (which meat is desired without bones by the consumer) due to the increase in weight and package.
As far as it is already known that leg bones (drumstick bones) are mechanically removed from poultry meat, a device of the prior art is equipped with a rotating chain which carries holding means with gripping arms for each leg passing through a cutting station in cycles. In this cutting station the bone is se~ered in its longitudinal direction by means of a saw. As a result, the divided meat can be dissociated more easily.

SUMMARY OF THE INVENTION
. ;,, It is the object of the present invention to provide a device for boning wings of poultry or the like, with the relatively thin bones (ulna and radius) being mechanically removed from the poultry meat during passage or in a cycle process and the subdivided bone parts being then ejected automatically.
. ~.
In a poultry boning device having holding means arranged on a transporting means which rotates in endless fashion within a machine frame, the holdlng means are equipped in accordance with the invention with a respective transverse reception means for receiving a wing, said means passing through a cutting station which divides the wing bones in a direction transverse to the longitudinal direction thereof and includes two cutting means rotating in the direction of movement and said means subsequently passing through a separating means dissociating the meat or the like from the bone.
After the wing bones have been cut through in a direction ~:
transverse to the longitudinal dire~tion thereof, the resultant three bone pieces are each stripped of meat and skin individually by means of the separating means and are subsequently ejected.
The wing bones may preferably be removed individually from the meat by means of gripping pliers, or they may be pressed out of the meat by means of abutment plates which are preferably perforated and by means of rams extending .,.~ .

The separating knives which dissociate the meat are arranged above this U-shaped and preferably rotatably mounted reception pockets and may have straight or bent blades. The blades may also be concave so as to be matched to the round shape of the bones. The separating knives may also serve as grippers in the case of blades that are pressed back into their slit-shaped reception means. These grippers are capable of removing the thickened cut end parts of the bones from the meat. To this end, the blades are each supported in the slit-shaped reception means on an inner pressure spring by which the blades are supported in a flexibly displaceable ~ way.

A poultry wing to be boned comprises an upper wing piece 10) and a lower wing piece (11). The meat o~ the upper wing piece (10) surrounds a so-called upper wing bone (12) whereas the meat of the lower wing piece (11) surrounds a bipartite lower wing bone (13) which naturally comprises an ulna (13a) and a radius (13b). The upper wing bone (12) on the one hand and ulna (13a) and rad~us (13b) of the lower wing bone (13) on the other hand are movably connected to each other via a joint (14).

transporting chain (19) of a bottom transportation means with holding means (18) and reception pockets (15, 16) held by said holding means and a middle centering mandrel (17) thereinbetween, with said assembly passing through a cutting station (21) with separating knives (43, 44, 49, 50 and 35).
Cutting station (21) carries lateral opposite skops (26, 27) and an upper retaining strip (28). Furthermore, there are provided lateral grippers (30) with gripper heads (32) on movable grippers arms (31~ for holding the bone to be processed and for pulling the same from the surrounding meat. Furthermore, rotating cutting knives (22) are provided for transversely dividing the bone into a plurality of pieces. The separating knives (43, 44, 49, 50) which are opposite each other in pairs (FIGS. 6a, 6b) are displaceably mounted in the cutting station for removing the meat from the bones.
A lateral abutment plate (59) is also supported in a i displaceable way and has the function to displace the separated bone piece (13) by 10 to 20 mm for tearing out the meat tendons.
To remove bones (12, 13) from the meat, the wings are inserted into two reception pockets (15, 16) that are spaced apart from each other at a specific distance (FIGS. 2-7).
These reception pockets (15, 16) have an approximately , U-shaped cross-section which can thus be adapted to the anatomical shape of the wing. The reception pockets may be supported in a rigid way or preferably in a slightly rotatable way on the transportation system.
Centering mandrel (17) is arranged between the two reception ; pockets (15, 16) at a distance from reception pocket (15) and also at a distance from reception pocket (16). The tip : 1 ;.,`~

; of this centering mandrel (17~ is oriented in an exactly ;~ opposite direction with respect to the lnsertion direction `~ of the wing into reception pockets tl5, 16). Reception ~i pockets (15, 16) and centering mandrel (17) are connected -~ via holding means (18) or the like in known fashion to a :j` transporting means, such as an endless rotating chain (19), ~- belt or the like.
: ~ ~ "
.; ~, ;~ A wing is inserted into the reception pockets (15, 16) in ,'.5~ such a way that joint ~14) is spitted onto the centering -~ mandrel (17) during the insertion operation. When the wing is inserted into these reception pockets (15, 16), the longitudinal bone direction of both the upper wing bone (12) and the lower wing bone (13) extends approximately at a ~^ right angle (horizontally) relative to the transportation direction (19) of the transporting chain or the like. These reception pockets (15, 16) are arranged on the transporting means in such a way that they are displaceable in a i direction perpendicular to the transportation direction of the transporting chain (19) or the like in accordance with arrow direction (20).
. ".,j In this position of the wing that is locally defined by the centering mandrel ~17) and the reception pockets (15, 16), the wing is supplied to a cutting station (21) (FIG. 3). The cutting station (21) may be supported in a sta-tionary way and may consist of circular cutting knives (22), saw blades or the like. The rotational direction of the cutting knives (22) is preferably opposite to the transportation direction ofjthe transporting chain (19). During passage through the cutting station (21~, cuts ~23) are made above and below joint (14) when being viewed in the longitudinal bone .~,'J direction. As a result of these cuts, joint (14) is severed from the wing. Furthermore, an outer connection skin (24~ is separated between upper wing piece (lO) and lower wing piece ~ (ll)o j,~,,l ,~ , . ';~, ~ 9 ~ ~867~7 It is only after the separating cut that the reception pockets (15, 16) assume their vertical position (erection) ~ith the aid of a suitable moving means.
The upper wing piece (10) and the lower wing piece (11) are now subjected to another processing step. Joint (14) which is covered by adhering skin resiclues may here be regarded as a waste product which need no longer be processed in a further step.
After cut (~3) has been made, the upper wing piece (10) and the lower wing piece (11) are further transported opposite to each other and diagonally to the outside, i.e. away from joint (14) in accordance with arrow direction (25) and seated in their reception pockets (15, 16), until each of them abuts on a lateral outer stop (26 and 27 respectively).
A possible lateral and continued transportation of the wing pieces (10, 1~) is stopped due to the abutment of the lower wing piece (ll) and the upper wing piece (10) on the respective lateral outer stops (26 and 27): Both the lower wing piece (11) and the upper wing piece (10) have reached the initial position required for further processing. This further processing starts after wing pieces (10, ll) have abutted against the lateral stops (26, 27) and after the transportation stop of the wing pieces (10, 11) caused thereby.
ti During its transportation in arrow direction (25) the upper wing piece (10) i5 moved below the upper retaining strip (28l) or the like, the end position of the upp~r wing piece (10) below said retaining strip (28) being reached when the upper wing piece (10~ abuts on a lateral stop (27). The position of the upper wing piece (10) is fixed by said upper retaining strip (28), which is necessary for further processing.

side is gripped from behind by a gripper (30) which is shaped in the form of pliers. This gripper (30) has, for instance, two gripper arms (31) that are opposite each other and rotate about a horizontal axis and on whose one end a respective gripper head (32) is arranged. The longitudinal directions of gripper arm (31) and gripper head (32) are at an angle to each other. Gripper head (32) has a reception recess (33) extending, for instance, in the longitudinal direction thereof. A knife (35) which is biased by a pressure spring (34) is supported in this reception recess (33) in a laterally displaceable way. Knife (35) can be displaced in the transportation direction of the transporting chain (19) and in a direction opposite thereto, as shown in FIG. 3. The vertical blade (58) of knife (35) is of a straight configuration, but may also have a concave shape. When being closed, i.e. during movement of the gripper arm (31) and thus of the gripper head (32) in arrow direction (36) and in arrow direction (37), respectively, knives (35) come to rest on the upper wing bone (12), thereby gripping the bone ball (29) from behind. The closed gripper (30) which is shaped in the form of pincers and biased to a certain degree is now rotated according to arrow direction (38) about a horizontal axis. As a result, the meat is somewhat dissociated from the bone, which facilitates subsequent removal of the bone (12~ from the upper wing piece (10).
A stripper plate (39) (FIG. 7) or the like is slid between gripper head (32) and the meat of the upper wing piece (10) after termination of the rotational movement of gripper (30) which is shaped in the form of pliers. The stripper plate (39) has the function to retain the meat during removal of the upper wing bone (12) from the upper wing piece (10) by gripper (30). Stripper plate (39) may also be arranged in a stationary way. In this case the upper wing piece (10) would be moved with its upper wing bone (12) into the stripper plate (39).
~., .j ".,.~
2~8~707 .: .
After the stripper plate (39) has been moved into position, gripper (30) which is shaped in the form of pliers is closed to a greater extent, i.e. the gripper arms (31) are further moved to each other to assume approximately the position shown in FIG. 7. After this position has been reached, gripper (30) is displaced according to arrow direction (40) until it assumes the position shown in FIG. 8, i.e. until the upper wlng bone (12) is fully removed from the upper wing piece (10). The meat of the upper wing piece (10) is now subjected to further processing, e.g., for making poultry sausage, poultry liverwurst or other delicatessen.
During this operation stop (26) must be removed from the path of movement.
Ulna (13a) and radius (13b), which jointly form the lower wing bone (13), are removed from the lower wing piece (11) ~, at the time when the upper wing bone (12) is removed from the upper wing piece (10).
As illustrated in FIG. 6, four separating knives (43, 44) ~; that are each under the action of a pressure spring (42) are operative below a bone ball (41) of the lower wing bone (13) in the area of ulna (13a) and radius (13b).
Out of two opposite and spaced-apart separating knives ~43, 44), the one separating knife (43) ls pressed under great pressure against the radius (13b) of the wing bone (13) from .l I thç outside. Another separating knife (44) is simultaneously ;~, pressed against the ulna (13a) of the lower wing bone (133, also under great pressure. The cutting geometry of said two ~i separating knives (43, 44) is preferably concave~ The blades (45, 46) of this shape therefore come to rest on ulna (13a) and radius (13b) of the lower wing bone (13) in such a way that they surround the same in an arcuate manner. The separating knives (43, 44) move towards the respective bones .~
; ~
. ,'r: , ~ . . . , .: , ... .
20~6707 in, and opposite to, the transporation direction of the transport.ing chain (19). The separating knives (43, 44) are mounted in laterally displaceable fashion in the reception recess (47) of a respective reception housing (48) under the action of the above-mentioned pressure spring (42). To be able to dissociate the meat between ulna (13a) and radius ~;~ (13b), additional separating knives (49, 50) are introduced into this area according to the illustration of FIGS. 6, 6a, 6b directly below the bone ball (43) vertically and at a right angle from both "the bottom" and "the top'~. These separating knives (49, 50) are preferably shaped like a wedge, their tips (51 and 52) respectively penetrating into the free space (53) formed between ulna (13a) and radius (13b). These separating knives (49, 50) overlap each other in this state according to the illustration of FIG. 6b and are each positioned on a part of the cross-sectional periphery of ulna (13a) and radius (13b). Hence, these separating knives (49, 50) simultaneously serve as counter-holders or as so-called "counter-pressure means" for the other separating knives (43, 44) already moved into their position previously.
The other separating knives (49, 50) that are biased by the pressure springs (42) to a certain degree are each displaceably supported in a reception recess (53) of a recept.ion housing (54) according to the insertion direction between ulna (13a) and radius (13b~. The meat of the lower wing piece (11) is pressed back, approximately as shown in the illustration of FIG. 7, in a direction perpendicular to the transporation direction of transporting chain (19) due to the introduction of the separating knives (43, 44, 49, 50) as shown in FIGS. 6b and 7.
~, When the separating knives (43, 44, 49, 50) are in position, according to the representation in FIGS. 6 and 7, ulna (13a) and radius (13b) and thus the entire lower wing bone (13) are displaced in the longitudinal direction of the lower '~, ,. - ,. , , : ~

wing bone by about 20 mm to the outside at a right angle and vertically opposite to the transportation direction of transporting chain (19). An abutment plate (59) which is moved, e.g., pneumatically or in a similar way, into the reception pocket (15) according to the illustration of FIG~
7 is used for displacement. During this displacement movement the tendons and the meat of the lower wing piece (11) are retained by the separa-ting knives (43, 44, 49, 50) while the bones are pressed further to the outside, pre*erably for about a third of their length.
After this operation has been ended, the bone ball (41) of the lower wing bone (13) is gripped from behind by so-called gripping pliers (55). The gripping pliers (55) are closed, thereby assuming the position shown in FIGo 7. The two gripper arms (56) of these gripping pliers (55) directly rest on ulna (13a) and radius (13b) below the bone ball (41) of the lower wing bone (13). The gripping pliers (55) are now moved in a direction corresponding to arrow direction (57), so that the whole bone of the lower wing (13) is removed from the lower wing piece (11).
~' ' The two aforementioned operations, i.e. removal of the upper wing bone (12) and of the lower wing bone (13) are carried out at the same time, so that after the removal of these two bones the meat of both the upper wing piece (10) and the lower wing piece (11) is available for further processing in accordance with the illustration of FIG. 8.

The above-described deskeletonization of poultry wings is ~,~ preferably applied to turkeys. It is however possible to deskeletonize the wings of other poultry types, i.e. those ~;~ of chicken, roosters, ducks, geese, phesants, etc. Moreover, the device is also suited for de~keletonizing corresponding extremities of other animals, such as hares, rabbits, etc~

j,:,.,.,i Reference numeral (60) designates an upper wing piece and reference numeral (61) a lower wing piece of a poultry wing.
These pieces are folded against each other in such a way that the connecting joint (64) is at one end and a bone ball (81) at the opposite end of ulna (63a) and radius (63b) of the lower wing bone (63), and another bone ball (79) of the upper wing bone (62) projects at the other side. The lower wing bone (63) and the upper wing bone (62) are approximately in parallel and are also surrounded by the meat and skin (64a) thereof.
The wing to be deskeletonized is prepared for boning in that its wing tip (not shown) that is not to be used is cut off in a preceding operation.
f ~,~`,'f A mechanical processing device for boning folded upper and lower wing pieces (60, 61) of this type has rotating endless .~i`1 'f transporting chains (69) within a machine frame (89) at the bottom side, like in the embodiment illustrated in FIGS.
1-8, with a suitable drive and guides (not shown) and includes holding means (68) and reception pockets (65) held thereby. These are mounted on the transporting chain (69) in ~f such a way that they are easily pivotable (rotatable) or can be displaced in a direction perpendicular to the transportation direction.
To remove the ~oint (64) and the bone balls (79, 81) from , the wing bones (62, 63), the reception pocket (65~ extends longitudinally at an angle of 30 to 50 (FIG. 9) relative to its motional direction, and the pieces are thus treated by a cutting station (71) which severs the joint (64) and ~',f ~ the bone balls (79, 81) as waste in parallel oblique cuts -~j (73) (relative to the longitudinal direction of the wing `~f bones). To this end, each reception pocket (65) has an approximately U-shaped cross-section which can thus be ~i,l .

This cutting station (71) is equipped with two separating -` knives (72) rotating in parallel with each other, e.g. in the form of circular saw blades which rotate, in a direction :; ~i ~` opposite to the direction of movement of the reception pocket (65), about a common driven shaft which is stationarily supported within the machine frame (~9).
, . .
The length of the reception pocket (65) is smaller than the distance between the two separating knives (72). As a result, the wing bones (62, 63) continue their travel after the separting operation whereas the bone balls (79, 81) on the one hand and the joint (64) on the other hand drop down due to gravity and can be removed from the machine.
However, this cutting station (71) may preferably be equipped with two rotating saw belts (not shown) that are arranged one after the other to rotate at an acute angle to each other and sever joint (64~ on the one hand and bone balls (79, 81) on the other hand at different cutting angles relative to the longitudinal bone direction and one after the other (FIG. 16).
: .s After the oblique cut (73) has been made, the cut lower wing bones (63a~ 63b) and the upper wing bone (62) are supplied ? to a dissociating means (70) acting as a separating means for meat, skin, etc. This means is equipped with two perforated plates (66, 67) that are displaceable relative to ~ each other and include two holes (74, 75) (FIGS. 10-12 and `~ 15) whose diameter corresponds to the outer diameter of ulna ¦ (63a) and radius (63b) of the lower wing bone (63).

As a consequence of the naturally complicated structure of chicken, duck or other poultry wings that have two thin bones, namely ulna and radius, there has so far been no device for mechanically dissociating the wing meat from the two interconnected bones in a satisfactory way. These two ~,~1 bones are not used by the final consumer and are therefore of great disadvantage to the sale of meat (which meat is desired without bones by the consumer) due to the increase in weight and package.
As far as it is already known that leg bones (drumstick bones) are mechanically removed from poultry meat, a device of the prior art is equipped with a rotating chain which carries holding means with gripping arms for each leg passing through a cutting station in cycles. In this cutting station the bone is se~ered in its longitudinal direction by means of a saw. As a result, the divided meat can be dissociated more easily.

SUMMARY OF THE INVENTION
. ;,, It is the object of the present invention to provide a device for boning wings of poultry or the like, with the relatively thin bones (ulna and radius) being mechanically removed from the poultry meat during passage or in a cycle process and the subdivided bone parts being then ejected automatically.
. ~.
In a poultry boning device having holding means arranged on a transporting means which rotates in endless fashion within a machine frame, the holdlng means are equipped in accordance with the invention with a respective transverse reception means for receiving a wing, said means passing through a cutting station which divides the wing bones in a direction transverse to the longitudinal direction thereof and includes two cutting means rotating in the direction of movement and said means subsequently passing through a separating means dissociating the meat or the like from the bone.
After the wing bones have been cut through in a direction ~:
transverse to the longitudinal dire~tion thereof, the resultant three bone pieces are each stripped of meat and skin individually by means of the separating means and are subsequently ejected.
The wing bones may preferably be removed individually from the meat by means of gripping pliers, or they may be pressed out of the meat by means of abutment plates which are preferably perforated and by means of rams extending .,.~ .

The separating knives which dissociate the meat are arranged above this U-shaped and preferably rotatably mounted reception pockets and may have straight or bent blades. The blades may also be concave so as to be matched to the round shape of the bones. The separating knives may also serve as grippers in the case of blades that are pressed back into their slit-shaped reception means. These grippers are capable of removing the thickened cut end parts of the bones from the meat. To this end, the blades are each supported in the slit-shaped reception means on an inner pressure spring by which the blades are supported in a flexibly displaceable ~ way.

A poultry wing to be boned comprises an upper wing piece 10) and a lower wing piece (11). The meat o~ the upper wing piece (10) surrounds a so-called upper wing bone (12) whereas the meat of the lower wing piece (11) surrounds a bipartite lower wing bone (13) which naturally comprises an ulna (13a) and a radius (13b). The upper wing bone (12) on the one hand and ulna (13a) and rad~us (13b) of the lower wing bone (13) on the other hand are movably connected to each other via a joint (14).
The processing device for deskeletonizing poultry wings which are equipped with ulna and radius includes a rotating ~'!

transporting chain (19) of a bottom transportation means with holding means (18) and reception pockets (15, 16) held by said holding means and a middle centering mandrel (17) thereinbetween, with said assembly passing through a cutting station (21) with separating knives (43, 44, 49, 50 and 35).
Cutting station (21) carries lateral opposite skops (26, 27) and an upper retaining strip (28). Furthermore, there are provided lateral grippers (30) with gripper heads (32) on movable grippers arms (31~ for holding the bone to be processed and for pulling the same from the surrounding meat. Furthermore, rotating cutting knives (22) are provided for transversely dividing the bone into a plurality of pieces. The separating knives (43, 44, 49, 50) which are opposite each other in pairs (FIGS. 6a, 6b) are displaceably mounted in the cutting station for removing the meat from the bones.
A lateral abutment plate (59) is also supported in a i displaceable way and has the function to displace the separated bone piece (13) by 10 to 20 mm for tearing out the meat tendons.
To remove bones (12, 13) from the meat, the wings are inserted into two reception pockets (15, 16) that are spaced apart from each other at a specific distance (FIGS. 2-7).
These reception pockets (15, 16) have an approximately , U-shaped cross-section which can thus be adapted to the anatomical shape of the wing. The reception pockets may be supported in a rigid way or preferably in a slightly rotatable way on the transportation system.
Centering mandrel (17) is arranged between the two reception ; pockets (15, 16) at a distance from reception pocket (15) and also at a distance from reception pocket (16). The tip : 1 ;.,`~

; of this centering mandrel (17~ is oriented in an exactly ;~ opposite direction with respect to the lnsertion direction `~ of the wing into reception pockets tl5, 16). Reception ~i pockets (15, 16) and centering mandrel (17) are connected -~ via holding means (18) or the like in known fashion to a :j` transporting means, such as an endless rotating chain (19), ~- belt or the like.
: ~ ~ "
.; ~, ;~ A wing is inserted into the reception pockets (15, 16) in ,'.5~ such a way that joint ~14) is spitted onto the centering -~ mandrel (17) during the insertion operation. When the wing is inserted into these reception pockets (15, 16), the longitudinal bone direction of both the upper wing bone (12) and the lower wing bone (13) extends approximately at a ~^ right angle (horizontally) relative to the transportation direction (19) of the transporting chain or the like. These reception pockets (15, 16) are arranged on the transporting means in such a way that they are displaceable in a i direction perpendicular to the transportation direction of the transporting chain (19) or the like in accordance with arrow direction (20).
. ".,j In this position of the wing that is locally defined by the centering mandrel ~17) and the reception pockets (15, 16), the wing is supplied to a cutting station (21) (FIG. 3). The cutting station (21) may be supported in a sta-tionary way and may consist of circular cutting knives (22), saw blades or the like. The rotational direction of the cutting knives (22) is preferably opposite to the transportation direction ofjthe transporting chain (19). During passage through the cutting station (21~, cuts ~23) are made above and below joint (14) when being viewed in the longitudinal bone .~,'J direction. As a result of these cuts, joint (14) is severed from the wing. Furthermore, an outer connection skin (24~ is separated between upper wing piece (lO) and lower wing piece ~ (ll)o j,~,,l ,~ , . ';~, ~ 9 ~ ~867~7 It is only after the separating cut that the reception pockets (15, 16) assume their vertical position (erection) ~ith the aid of a suitable moving means.
The upper wing piece (10) and the lower wing piece (11) are now subjected to another processing step. Joint (14) which is covered by adhering skin resiclues may here be regarded as a waste product which need no longer be processed in a further step.
After cut (~3) has been made, the upper wing piece (10) and the lower wing piece (11) are further transported opposite to each other and diagonally to the outside, i.e. away from joint (14) in accordance with arrow direction (25) and seated in their reception pockets (15, 16), until each of them abuts on a lateral outer stop (26 and 27 respectively).
A possible lateral and continued transportation of the wing pieces (10, 1~) is stopped due to the abutment of the lower wing piece (ll) and the upper wing piece (10) on the respective lateral outer stops (26 and 27): Both the lower wing piece (11) and the upper wing piece (10) have reached the initial position required for further processing. This further processing starts after wing pieces (10, ll) have abutted against the lateral stops (26, 27) and after the transportation stop of the wing pieces (10, 11) caused thereby.
ti During its transportation in arrow direction (25) the upper wing piece (10) i5 moved below the upper retaining strip (28l) or the like, the end position of the upp~r wing piece (10) below said retaining strip (28) being reached when the upper wing piece (10~ abuts on a lateral stop (27). The position of the upper wing piece (10) is fixed by said upper retaining strip (28), which is necessary for further processing.

side is gripped from behind by a gripper (30) which is shaped in the form of pliers. This gripper (30) has, for instance, two gripper arms (31) that are opposite each other and rotate about a horizontal axis and on whose one end a respective gripper head (32) is arranged. The longitudinal directions of gripper arm (31) and gripper head (32) are at an angle to each other. Gripper head (32) has a reception recess (33) extending, for instance, in the longitudinal direction thereof. A knife (35) which is biased by a pressure spring (34) is supported in this reception recess (33) in a laterally displaceable way. Knife (35) can be displaced in the transportation direction of the transporting chain (19) and in a direction opposite thereto, as shown in FIG. 3. The vertical blade (58) of knife (35) is of a straight configuration, but may also have a concave shape. When being closed, i.e. during movement of the gripper arm (31) and thus of the gripper head (32) in arrow direction (36) and in arrow direction (37), respectively, knives (35) come to rest on the upper wing bone (12), thereby gripping the bone ball (29) from behind. The closed gripper (30) which is shaped in the form of pincers and biased to a certain degree is now rotated according to arrow direction (38) about a horizontal axis. As a result, the meat is somewhat dissociated from the bone, which facilitates subsequent removal of the bone (12~ from the upper wing piece (10).
A stripper plate (39) (FIG. 7) or the like is slid between gripper head (32) and the meat of the upper wing piece (10) after termination of the rotational movement of gripper (30) which is shaped in the form of pliers. The stripper plate (39) has the function to retain the meat during removal of the upper wing bone (12) from the upper wing piece (10) by gripper (30). Stripper plate (39) may also be arranged in a stationary way. In this case the upper wing piece (10) would be moved with its upper wing bone (12) into the stripper plate (39).
~., .j ".,.~
2~8~707 .: .
After the stripper plate (39) has been moved into position, gripper (30) which is shaped in the form of pliers is closed to a greater extent, i.e. the gripper arms (31) are further moved to each other to assume approximately the position shown in FIG. 7. After this position has been reached, gripper (30) is displaced according to arrow direction (40) until it assumes the position shown in FIG. 8, i.e. until the upper wlng bone (12) is fully removed from the upper wing piece (10). The meat of the upper wing piece (10) is now subjected to further processing, e.g., for making poultry sausage, poultry liverwurst or other delicatessen.
During this operation stop (26) must be removed from the path of movement.
Ulna (13a) and radius (13b), which jointly form the lower wing bone (13), are removed from the lower wing piece (11) ~, at the time when the upper wing bone (12) is removed from the upper wing piece (10).
As illustrated in FIG. 6, four separating knives (43, 44) ~; that are each under the action of a pressure spring (42) are operative below a bone ball (41) of the lower wing bone (13) in the area of ulna (13a) and radius (13b).
Out of two opposite and spaced-apart separating knives ~43, 44), the one separating knife (43) ls pressed under great pressure against the radius (13b) of the wing bone (13) from .l I thç outside. Another separating knife (44) is simultaneously ;~, pressed against the ulna (13a) of the lower wing bone (133, also under great pressure. The cutting geometry of said two ~i separating knives (43, 44) is preferably concave~ The blades (45, 46) of this shape therefore come to rest on ulna (13a) and radius (13b) of the lower wing bone (13) in such a way that they surround the same in an arcuate manner. The separating knives (43, 44) move towards the respective bones .~

20~6707 in, and opposite to, the transporation direction of the transport.ing chain (19). The separating knives (43, 44) are mounted in laterally displaceable fashion in the reception recess (47) of a respective reception housing (48) under the action of the above-mentioned pressure spring (42). To be able to dissociate the meat between ulna (13a) and radius ~;~ (13b), additional separating knives (49, 50) are introduced into this area according to the illustration of FIGS. 6, 6a, 6b directly below the bone ball (43) vertically and at a right angle from both "the bottom" and "the top'~. These separating knives (49, 50) are preferably shaped like a wedge, their tips (51 and 52) respectively penetrating into the free space (53) formed between ulna (13a) and radius (13b). These separating knives (49, 50) overlap each other in this state according to the illustration of FIG. 6b and are each positioned on a part of the cross-sectional periphery of ulna (13a) and radius (13b). Hence, these separating knives (49, 50) simultaneously serve as counter-holders or as so-called "counter-pressure means" for the other separating knives (43, 44) already moved into their position previously.
The other separating knives (49, 50) that are biased by the pressure springs (42) to a certain degree are each displaceably supported in a reception recess (53) of a recept.ion housing (54) according to the insertion direction between ulna (13a) and radius (13b~. The meat of the lower wing piece (11) is pressed back, approximately as shown in the illustration of FIG. 7, in a direction perpendicular to the transporation direction of transporting chain (19) due to the introduction of the separating knives (43, 44, 49, 50) as shown in FIGS. 6b and 7.
~, When the separating knives (43, 44, 49, 50) are in position, according to the representation in FIGS. 6 and 7, ulna (13a) and radius (13b) and thus the entire lower wing bone (13) are displaced in the longitudinal direction of the lower '~, ,. - ,. , , : ~

wing bone by about 20 mm to the outside at a right angle and vertically opposite to the transportation direction of transporting chain (19). An abutment plate (59) which is moved, e.g., pneumatically or in a similar way, into the reception pocket (15) according to the illustration of FIG~
7 is used for displacement. During this displacement movement the tendons and the meat of the lower wing piece (11) are retained by the separa-ting knives (43, 44, 49, 50) while the bones are pressed further to the outside, pre*erably for about a third of their length.
After this operation has been ended, the bone ball (41) of the lower wing bone (13) is gripped from behind by so-called gripping pliers (55). The gripping pliers (55) are closed, thereby assuming the position shown in FIGo 7. The two gripper arms (56) of these gripping pliers (55) directly rest on ulna (13a) and radius (13b) below the bone ball (41) of the lower wing bone (13). The gripping pliers (55) are now moved in a direction corresponding to arrow direction (57), so that the whole bone of the lower wing (13) is removed from the lower wing piece (11).
~' ' The two aforementioned operations, i.e. removal of the upper wing bone (12) and of the lower wing bone (13) are carried out at the same time, so that after the removal of these two bones the meat of both the upper wing piece (10) and the lower wing piece (11) is available for further processing in accordance with the illustration of FIG. 8.

The above-described deskeletonization of poultry wings is ~,~ preferably applied to turkeys. It is however possible to deskeletonize the wings of other poultry types, i.e. those ~;~ of chicken, roosters, ducks, geese, phesants, etc. Moreover, the device is also suited for de~keletonizing corresponding extremities of other animals, such as hares, rabbits, etc~

j,:,.,.,i Reference numeral (60) designates an upper wing piece and reference numeral (61) a lower wing piece of a poultry wing.
These pieces are folded against each other in such a way that the connecting joint (64) is at one end and a bone ball (81) at the opposite end of ulna (63a) and radius (63b) of the lower wing bone (63), and another bone ball (79) of the upper wing bone (62) projects at the other side. The lower wing bone (63) and the upper wing bone (62) are approximately in parallel and are also surrounded by the meat and skin (64a) thereof.
The wing to be deskeletonized is prepared for boning in that its wing tip (not shown) that is not to be used is cut off in a preceding operation.
f ~,~`,'f A mechanical processing device for boning folded upper and lower wing pieces (60, 61) of this type has rotating endless .~i`1 'f transporting chains (69) within a machine frame (89) at the bottom side, like in the embodiment illustrated in FIGS.
1-8, with a suitable drive and guides (not shown) and includes holding means (68) and reception pockets (65) held thereby. These are mounted on the transporting chain (69) in ~f such a way that they are easily pivotable (rotatable) or can be displaced in a direction perpendicular to the transportation direction.
To remove the ~oint (64) and the bone balls (79, 81) from , the wing bones (62, 63), the reception pocket (65~ extends longitudinally at an angle of 30 to 50 (FIG. 9) relative to its motional direction, and the pieces are thus treated by a cutting station (71) which severs the joint (64) and ~',f ~ the bone balls (79, 81) as waste in parallel oblique cuts -~j (73) (relative to the longitudinal direction of the wing `~f bones). To this end, each reception pocket (65) has an approximately U-shaped cross-section which can thus be ~i,l .

This cutting station (71) is equipped with two separating -` knives (72) rotating in parallel with each other, e.g. in the form of circular saw blades which rotate, in a direction :; ~i ~` opposite to the direction of movement of the reception pocket (65), about a common driven shaft which is stationarily supported within the machine frame (~9).
, . .
The length of the reception pocket (65) is smaller than the distance between the two separating knives (72). As a result, the wing bones (62, 63) continue their travel after the separting operation whereas the bone balls (79, 81) on the one hand and the joint (64) on the other hand drop down due to gravity and can be removed from the machine.
However, this cutting station (71) may preferably be equipped with two rotating saw belts (not shown) that are arranged one after the other to rotate at an acute angle to each other and sever joint (64~ on the one hand and bone balls (79, 81) on the other hand at different cutting angles relative to the longitudinal bone direction and one after the other (FIG. 16).
: .s After the oblique cut (73) has been made, the cut lower wing bones (63a~ 63b) and the upper wing bone (62) are supplied ? to a dissociating means (70) acting as a separating means for meat, skin, etc. This means is equipped with two perforated plates (66, 67) that are displaceable relative to ~ each other and include two holes (74, 75) (FIGS. 10-12 and `~ 15) whose diameter corresponds to the outer diameter of ulna ¦ (63a) and radius (63b) of the lower wing bone (63).

.,. . ~
In the embodiment of the perforated plates (66, 67), as is ~;~ shown in FIGS. 13 and 14, only one hole (80) is provided in the perforated plates (66, 67) through which the upper wing ~1 bone (62j is pressed, with the inner edge of the hole respectively acting as a strlpper surface.
, ~
The one peforated plate (19) is preferably fixedly arranged and the other perforated plate (67) is movably supported -i relative thereto.
Furthermore, instead o~ one perforated plate with a specific diameter corresponding to the bone diameter, two perforated plates with increased holes are preferably supported adjacent to each other, the effective hole diameter being changeable in a variable way by displacing said perforated plates in one plane so as to achieve an excellent separating action of the inner edges.
To remove the various wing bones (62, 63) by a pressing operation, the perforated plates (66, 67) have arranged upstream thereof driven rams (76-78~ which reciprocate in a direction perpendicular thereto and abut on the front faces of the bones (62, 63~ and press the same (see motion arrows) -~ through the holes (74, 75, 80) of the perforated plates (66, `,`3 67), whereby the dissociating meat (64a), etc. is compressed into a removable piece of meat also with the aid of the moving perforated plate (77). This meat can then be delivered to the consumer in any desired specification.

, In a slightly modified embodiment (FIGS. 16-18), a divided plate (66a, 66b) may be used as a clamp instead of a one-part perforated plate (66). This clamp surrounds the wing bones (62, 63) from both sides, with a hinge (66c) holding the two perforated plate halves (66a, 66h) together.
These divided perforated plates (66a, 66b) may also include three holes, so that all three bones (62, 63a, 63b) can be pressed through these divided perforated plates (66a, 66b) together with the rams (76-78), depicted and illustrated in FIGS. 12, 15, in this way and at the same time. The severed meat is here also compressed and the movable perforated plate (67) forms the abutment.
A divided perforated plate (66a, 66b) of this type may first retain the wings (60, 61) as a separate fixing clamp instead of a reception pocket (65) during processing (severing of joint (64) and of bone balls (79, 81)).
