Abstract
Abstract A small poultry limb, such as a turkey drumstick, is clamped to a longitudinally movable ram. The limb is thrust by the ram through a first resiliently flexible stripping device and a second stripping device. The bone passes through the stripping devices but the skin and tendons clamped to the ram are held and turned back over the ram thus exposing the meat for stripping.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
100 words
A method of removing meat from a bone of a poultry limb having a first end and a second end, comprising: clamping said first end of said poultry limb into a forward end of a ram with said second end of said poultry limb extending away from said ram in an axial direction with respect to said ram; and axially advancing said ram and poultry limb through a first aperture in a first stripping device so that said meat is turned back over an outer periphery of said ram and falls away from or is readily removed from said ram.
Claim 2
Independent Claim
100 words
A method of removing meat from a bone of a poultry limb having a first end and a second end, comprising: clamping said first end of said poultry limb into a forward end of a ram with said second end of said poultry limb extending away from said ram in an axial direction with respect to said ram; and axially advancing said ram and poultry limb through a first aperture in a first stripping device so that said meat is turned back over an outer periphery of said ram and falls away from or is readily removed from said ram.
Claim 3
Dependent Claim
56 words
The method according to claim 1, wherein said poultry limb comprises a bone, meat, tendons and skin, said first end being smaller than said second end, and wherein said first end is clamped into said forward end of said ram in such a manner that said tendons and skin are firmly held with said first end.
Claim 4
Dependent Claim
38 words
The method according to claim 2, wherein said ram is further axially advanced through a second aperture in a second stripping device to remove meat remaining on said ram while said tendons and skin remain on said ram.
Claim 5
Dependent Claim
33 words
The method according to claim 3, wherein said ram is subsequently retracted through said first and second apertures to roll back said tendons and skin off of said outer periphery of said ram.
Claim 6
Dependent Claim
113 words
Apparatus for removing meat from a bone of a poultry limb having a first end and a second end, comprising: a ram comprising a clamping device in a forward end thereof for clamping said first end of said poultry limb; a first stripping device comprising a first aperture axially forward of said forward end of said ram; said first aperture being adapted to allow axial passage of said bone and said forward end of said ram therethrough while stripping said meat away from said bone and turning said meat over an outer periphery of said ram; at least said forward end of said ram being adapted to advance axially through said first aperture.
Claim 7
Dependent Claim
113 words
Apparatus for removing meat from a bone of a poultry limb having a first end and a second end, comprising: a ram comprising a clamping device in a forward end thereof for clamping said first end of said poultry limb; a first stripping device comprising a first aperture axially forward of said forward end of said ram; said first aperture being adapted to allow axial passage of said bone and said forward end of said ram therethrough while stripping said meat away from said bone and turning said meat over an outer periphery of said ram; at least said forward end of said ram being adapted to advance axially through said first aperture.
Claim 8
Dependent Claim
56 words
Apparatus according to claim 5, further comprising a second stripping device, said second stripping device defining a second aperture axially aligned with said ram, said second aperture being adapted to allow axial passage of said bone and said forward end of said ram therethrough while stripping remaining meat away from said outer periphery of said ram.
Claim 9
Dependent Claim
26 words
Apparatus according to claim 6, wherein said second aperture is adapted to allow skin and tendons clamped to said ram to pass therethrough with said ram.
Claim 10
Dependent Claim
33 words
Apparatus according to claim 6, wherein said first aperture is defined by resiliently flexible stripping elements, said aperture being smaller than a maximum diameter of a poultry limb bone to be passed therethrough.
Claim 11
Dependent Claim
20 words
Apparatus according to claim 8, wherein said stripping elements are defined by crossed slits in a piece of elastomeric material.
Claim 12
Dependent Claim
31 words
Apparatus according to claim 7, wherein said second stripping device defining said second aperture is rigid, and said second aperture has a diameter slightly larger than a diameter of said ram.
Claim 13
Dependent Claim
31 words
Apparatus according to claim 8, wherein said second stripping device defining said second aperture is rigid, and said second aperture has a diameter slightly larger than a diameter of said ram.
Claim 14
Dependent Claim
22 words
Apparatus according to claim 5, further comprising means for advancing and retracting said forward end of said ram through said first aperture.
Claim 15
Dependent Claim
24 words
Apparatus according to claim 6, further comprising means for advancing and retracting said forward end of said ram through said first and second apertures.
Claim 16
Dependent Claim
12 words
Apparatus according to claim 5, wherein said clamping device comprises part-spherical jaws.
Claim 17
Dependent Claim
12 words
Apparatus according to claim 6, wherein said clamping device comprises part-spherical jaws.
