Abstract
Abstract A fish can filling apparatus including a conveyor for advancing fish fillets past a rotary cutter which cuts the fish into segments and then advances the segments into a compression chamber. A piston then transfers the segments of fish against a forming surface corresponding in shape to a portion of the side wall of the can to be filled. Shaping knives are then closed to form part of the remainder of the fish segments into a shape corresponding to the shape of the remaining portion of the side walls of the can. A reciprocating piston then transfers the formed charge of fish into the open can, and when approaching the end of its transfer stroke and at the beginning of its return stroke, the piston is oscillated about its axis to minimize the tendency of the fish to stick to the piston and also to prevent flakes or chips of the fish from being pulled off the surface of the charge of fish.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
105 words
Apparatus for canning fish of the type including a fish charge forming means and a formed fish charge transfer means to transfer said fish charge into a can comprising an axially displaceable piston, and means for driving said piston in an axial to and fro motion defining a transfer and withdrawal stroke, wherein the improvement comprises piston oscillating means for oscillating said piston around its axis, said piston oscillating means including means for oscillating said piston in a timed relationship to said axial piston motion such that said piston oscillates only during the end of the transfer and the beginning of a subsequent withdrawal stroke.
Claim 2
Dependent Claim
105 words
Apparatus for canning fish of the type including a fish charge forming means and a formed fish charge transfer means to transfer said fish charge into a can comprising an axially displaceable piston, and means for driving said piston in an axial to and fro motion defining a transfer and withdrawal stroke, wherein the improvement comprises piston oscillating means for oscillating said piston around its axis, said piston oscillating means including means for oscillating said piston in a timed relationship to said axial piston motion such that said piston oscillates only during the end of the transfer and the beginning of a subsequent withdrawal stroke.
Claim 3
Dependent Claim
141 words
Improved apparatus for canning fish of the type including a fish charge forming means and a formed fish charge transfer means to transfer said fish charge into a can; said transfer means comprising an axially displaceable piston, means for driving said piston in a to and fro motion, and piston oscillating means driven from said drive means for oscillating said piston around its axis; wherein said piston oscillating means includes a disc mounted on a rotatable shaft, a cam track in said disc, a roller carried by a rider and engaging said track, a rod hinged to said rider, the other end of said rod being swivelly connected to a projection on the base of said piston, whereby said rotatable shaft is driven by a cam shaft carrying a cam to impart said to and fro axial motion to the piston.
Claim 4
Dependent Claim
141 words
Improved apparatus for canning fish of the type including a fish charge forming means and a formed fish charge transfer means to transfer said fish charge into a can; said transfer means comprising an axially displaceable piston, means for driving said piston in a to and fro motion, and piston oscillating means driven from said drive means for oscillating said piston around its axis; wherein said piston oscillating means includes a disc mounted on a rotatable shaft, a cam track in said disc, a roller carried by a rider and engaging said track, a rod hinged to said rider, the other end of said rod being swivelly connected to a projection on the base of said piston, whereby said rotatable shaft is driven by a cam shaft carrying a cam to impart said to and fro axial motion to the piston.
Claim 5
Independent Claim
137 words
An apparatus of the type for feeding fish into a container comprising means for forming a charge of fish in the shape of the container, and transfer means for moving the formed charge of fish into the container, said transfer means including a reciprocating transfer piston movable through a transfer stroke and a withdrawal stroke, said piston having a fish contacting surface and a longitudinal axis and being reciprocated in a direction parallel to said longitudinal axis between a fish receiving position and a transfer position, wherein the improvement comprises means for oscillating said piston about its longitudinal axis only when said piston approaches the end of its transfer stroke and begins its withdrawal stroke for utilizing rotative momentum imparted to the fish charge for breaking adhesion between said fish contacting surface and the charge of fish.
Claim 6
Independent Claim
137 words
An apparatus of the type for feeding fish into a container comprising means for forming a charge of fish in the shape of the container, and transfer means for moving the formed charge of fish into the container, said transfer means including a reciprocating transfer piston movable through a transfer stroke and a withdrawal stroke, said piston having a fish contacting surface and a longitudinal axis and being reciprocated in a direction parallel to said longitudinal axis between a fish receiving position and a transfer position, wherein the improvement comprises means for oscillating said piston about its longitudinal axis only when said piston approaches the end of its transfer stroke and begins its withdrawal stroke for utilizing rotative momentum imparted to the fish charge for breaking adhesion between said fish contacting surface and the charge of fish.
Claim 7
Independent Claim
200 words
An apparatus for feeding fish into a container comprising a knife shaft, a rotary knife secured to said shaft and having a relieved fish receiving portion and a large diameter fish cutting portion, means for feeding fish fillet to said knife and through said relieved portion whereby said knife severs sections from the fillet, means for forming the severed sections of fish into a charge of fish in the shape of the container, means for moving the container into position to receive said charge of fish, a driven shaft, drive means interconnecting said knife shaft and said driven shaft, a transfer piston having a fish contacting surface and a longitudinal axis mounted for reciprocable movement in a direction parallel to said longitudinal axis between a fish receiving position and a transfer position, a reciprocating cam connected to said driven shaft, first linkage means interconnecting said first shaft and said piston for reciprocating said piston between said fish receiving and said transfer position, an oscillating cam connected to said knife shaft, and oscillating linkage means interconnecting said oscillating cAm with said piston for causing said piston to oscillate when said fish contacting surface is in contact with the charge of fish.
Claim 8
Independent Claim
