Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
146 words
A poultry lung and kidney removal device comprising a housing, a source of vacuum, a vacuum tube supported in said housing, said tube being connected to said vacuum source at one end and having a nozzle section at the other end, an air pressure actuated vacuum valve mounted on said housing for controlling the vacuum in said tube, said vacuum valve including a piston and a piston rod positioned for movement to a blocking position in said vacuum tube, a source of air under pressure, a trigger actuated air valve mounted in said housing and being connected to said vacuum valve and to said source of air under pressure, for selectively applying air under pressure to said vacuum valve to open said valve and draw a vacuum in said tube, and means for biasing said piston and rod to the blocking position in said vacuum tube.
Claim 2
Dependent Claim
146 words
A poultry lung and kidney removal device comprising a housing, a source of vacuum, a vacuum tube supported in said housing, said tube being connected to said vacuum source at one end and having a nozzle section at the other end, an air pressure actuated vacuum valve mounted on said housing for controlling the vacuum in said tube, said vacuum valve including a piston and a piston rod positioned for movement to a blocking position in said vacuum tube, a source of air under pressure, a trigger actuated air valve mounted in said housing and being connected to said vacuum valve and to said source of air under pressure, for selectively applying air under pressure to said vacuum valve to open said valve and draw a vacuum in said tube, and means for biasing said piston and rod to the blocking position in said vacuum tube.
Claim 3
Dependent Claim
89 words
The device according to claim 1 wherein said air valve includes a valve body having a central passage, said central passage having an air inlet at one end connected to the source of air under pressure, and a discharge outlet at the other end, an annular air groove in the outer surface of said valve body connected to said cEntral passage and to said vacuum valve and a valve stem within said central passage for selectively connecting said air groove to said air inlet or to said discharge outlet.
Claim 4
Dependent Claim
42 words
The device according to claim 2 wherein said source of air includes an inline oiler means and said valve body includes a discharge groove connected to vent oil laden air discharged from said central passage to the surface of said piston rod.
Claim 5
Dependent Claim
35 words
The device according to claim 2 wherein said valve stem includes a first seal for sealing the inlet to the central passage and a second seal for sealing the discharge end of the central passage.
Claim 6
Dependent Claim
97 words
A poultry lung and kidney removal vacuum device comprising a housing, a vacuum source, a vacuum tube connected to said vacuum source and mounted in said housing, a nozzle section on one end of said vacuum tube for removing the lung and kidney from poultry, a piston actuated valve mounted on said housing and being responsive to air pressure for controlling the vacuum in said vacuum tube, a source of air under pressure, and a trigger actuated air pressure control valve in said housing for selectively connecting said source of air pressure to said piston actuated valve.
Claim 7
Dependent Claim
97 words
A poultry lung and kidney removal vacuum device comprising a housing, a vacuum source, a vacuum tube connected to said vacuum source and mounted in said housing, a nozzle section on one end of said vacuum tube for removing the lung and kidney from poultry, a piston actuated valve mounted on said housing and being responsive to air pressure for controlling the vacuum in said vacuum tube, a source of air under pressure, and a trigger actuated air pressure control valve in said housing for selectively connecting said source of air pressure to said piston actuated valve.
Claim 8
Dependent Claim
52 words
The device according to claim 5 wherein said piston actuated valve comprises a cylinder body mounted on said housing and having a cylinder therein, a piston having a piston head mounted in said cylinder and a piston rod connected to said piston for movement to a blocking position in said vacuum tube.
Claim 9
Dependent Claim
68 words
The device according to claim 6 including a first series of ports in said housing connecting said control valve to said cylinder in said cylinder body, said control valve including a valve body having a central passage adapted to be connected to a source of air under pressure and a valve positioned in said passage for selectively connecting said central passage to said ports to pressurize said piston.
Claim 10
Dependent Claim
108 words
A poultry lung and kidney removal vacuum device comprising a housing having first, second and third air passages, a vacuum tube mounted in said first passage and being in communication with said third passage, a piston actuated control valve mounted on said housing and including a piston rod mounted for movement into said third passage for controlling the vacuum in said vacuum tube, an air pressure control valve mounted in said second passage, and a first series of ports connecting said second passage to said control valve whereby opening of said control valve connects said second passage to said third passage and actuates said pressure actuated control valve.
Claim 11
Dependent Claim
108 words
A poultry lung and kidney removal vacuum device comprising a housing having first, second and third air passages, a vacuum tube mounted in said first passage and being in communication with said third passage, a piston actuated control valve mounted on said housing and including a piston rod mounted for movement into said third passage for controlling the vacuum in said vacuum tube, an air pressure control valve mounted in said second passage, and a first series of ports connecting said second passage to said control valve whereby opening of said control valve connects said second passage to said third passage and actuates said pressure actuated control valve.
Claim 12
Dependent Claim
110 words
The device according to claim 8 wherein said air pressure control valve includes a valve body having a central passage, said central passage having an inlet at one end connected to a source of air under pressure, and a valve having a valve stem positioned in said central passage, a first seal on the end of said valve stem positioned to close said central passage and a trigger pivotally mounted on said valve body in a position to engage said valve, whereby on movement of said trigger against said valve said valve stem will be moved in said central passage to an open position with respect to said central passage.
Claim 13
Dependent Claim
39 words
The device according to claim 8 wherein said housing includes a first series of ports connecting said third passage to said piston actuated control valve and a second series of ports connecting said second passage to said third passage.
