Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
144 words
A cutter apparatus suitable for use in processing poultry or the like, comprising a hollow cylindrical cutter having a cutting surface at one end thereof, a rotatable shaft for supporting said cutter, means for rotating said shaft, fluid passage means defined in said rotatable shaft communicating with the interior of said hollow cutter, a housing positioned about said shaft, said housing having fluid passage means formed therein which cooperate with said fluid passage means defined in said rotatable shaft, a valve for controlling the passage of fluid through said fluid passage means, said fluid passage means being connectable to a vacuum pump to create a partial vacuum in said cutter, and a trigger assembly for actuating said means for rotating said shaft, said trigger assembly also including means for controlling said valve to connect the interior of said hollow cutter to the vacuum pump.
Claim 2
Dependent Claim
144 words
A cutter apparatus suitable for use in processing poultry or the like, comprising a hollow cylindrical cutter having a cutting surface at one end thereof, a rotatable shaft for supporting said cutter, means for rotating said shaft, fluid passage means defined in said rotatable shaft communicating with the interior of said hollow cutter, a housing positioned about said shaft, said housing having fluid passage means formed therein which cooperate with said fluid passage means defined in said rotatable shaft, a valve for controlling the passage of fluid through said fluid passage means, said fluid passage means being connectable to a vacuum pump to create a partial vacuum in said cutter, and a trigger assembly for actuating said means for rotating said shaft, said trigger assembly also including means for controlling said valve to connect the interior of said hollow cutter to the vacuum pump.
Claim 3
Dependent Claim
33 words
The cutter apparatus of claim 1 in which said valve has two inlet passages, said valve has a spool, said spool directs the flow of fluid between said passages and said fluid passage.
Claim 4
Dependent Claim
118 words
A cutter apparatus suitable for use in processing poultry or the like, comprising a hollow cylindrical cutter having a cutting surface at one end thereof, a rotatable shaft for supporting said cutter at the other end thereof, means for rotating said shaft, fluid passage means defined in said rotatable shaft, a housing positioned about said shaft, said housing having fluid passage means formed therein which cooperate with said fluid passage means of said rotatable shaft, a valve for controlling the passage of fluid through said fluid passage means, said passage being connectable to a vacuum pump to create a partial vacuum in said cutter, and means for causing the expulsion of fluid through said valve and said cutter.
Claim 5
Dependent Claim
118 words
A cutter apparatus suitable for use in processing poultry or the like, comprising a hollow cylindrical cutter having a cutting surface at one end thereof, a rotatable shaft for supporting said cutter at the other end thereof, means for rotating said shaft, fluid passage means defined in said rotatable shaft, a housing positioned about said shaft, said housing having fluid passage means formed therein which cooperate with said fluid passage means of said rotatable shaft, a valve for controlling the passage of fluid through said fluid passage means, said passage being connectable to a vacuum pump to create a partial vacuum in said cutter, and means for causing the expulsion of fluid through said valve and said cutter.
Claim 6
Dependent Claim
84 words
An eviscerating tool comprising a housing member, a hollow cylindrical cutter having a cutting surface at one end thereof, means rotatably mounting said cutter in said housing, means carried in said housing for driving said cutter, fluid passage means defined in said housing to the interior of said cutter, means connectable to said fluid passage means for creating a partial vacuum with said cutter, and means for connecting said passage means to a fluid line to expel material from the interior of said cutter.
Claim 7
Dependent Claim
84 words
An eviscerating tool comprising a housing member, a hollow cylindrical cutter having a cutting surface at one end thereof, means rotatably mounting said cutter in said housing, means carried in said housing for driving said cutter, fluid passage means defined in said housing to the interior of said cutter, means connectable to said fluid passage means for creating a partial vacuum with said cutter, and means for connecting said passage means to a fluid line to expel material from the interior of said cutter.
Claim 8
Dependent Claim
32 words
A cutter apparatus according to claim 4 further including first valve means for connecting said passage to a vacuum-creating means, said second valve means for connecting said passage to said fluid line.
Claim 9
Dependent Claim
34 words
A cutter apparatus according to claim 5 wherein said fluid line may be connected to said passage when said first valve means is positioned to provide communication between said passage and said vacuum-creating means.
Claim 10
Dependent Claim
96 words
A cutter apparatus suitable for use in processing poultry and the like Comprising a cylindrical cutter having a cutter surface at one end thereof, a rotatable shaft for supporting said cutter at the other end thereof, a fluid-actuated motor for rotating said shaft, fluid passage means defined in said rotatable shaft communicating with the interior of said hollow cutter, means for connecting said fluid motor means to a source of fluid pressure, timing means, said timing means being responsive to fluid actuation of said motor to interrupt fluid to said motor after a predetermined time interval.
Claim 11
Dependent Claim
96 words
A cutter apparatus suitable for use in processing poultry and the like Comprising a cylindrical cutter having a cutter surface at one end thereof, a rotatable shaft for supporting said cutter at the other end thereof, a fluid-actuated motor for rotating said shaft, fluid passage means defined in said rotatable shaft communicating with the interior of said hollow cutter, means for connecting said fluid motor means to a source of fluid pressure, timing means, said timing means being responsive to fluid actuation of said motor to interrupt fluid to said motor after a predetermined time interval.
Claim 12
Dependent Claim
141 words
A cutter apparatus suitable for use in processing poultry or the like, comprising a hollow cylindrical cutter having a cutting surface at one end thereof, a guide shaft having a portion thereof positioned within the confines of said cutter and another portion thereof extending beyond the cutting surface of said cutter, a rotatable shaft supporting said cutter, means for rotating said shaft, a first passage defined in said rotatable shaft to provide fluid communication to the inside of said cutter, a housing for said rotatable shaft, a second passage defined in said housing providing communication first to said passage, first coupling means for connecting said second passage to a vacuum source, second coupling means for connecting said second passage to a source of rinsing liquid, and valve means positioned in said housing to connect said second passage to said coupling means.
Claim 13
Dependent Claim
141 words
