Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
126 words
In a staking mechanism for staking an end cap onto a magazine, the combination comprising: means for holding an end cap and magazine in alignment with one another; means for moving the end cap onto the magazine; staking means movable with said moving means and operated in timed relation thereto when enabled for staking the mounted end cap to the magazine; said staking means being mounted for limited movement relative to said cap moving means; detecting means responsive to relative movement between said moving means and said staking means for detecting interference between the end cap and magazine prior to the staking of the end cap onto the magazine; and disabling means responsive to said detecting means for disabling said staking means when interference is detected.
Claim 2
Dependent Claim
126 words
In a staking mechanism for staking an end cap onto a magazine, the combination comprising: means for holding an end cap and magazine in alignment with one another; means for moving the end cap onto the magazine; staking means movable with said moving means and operated in timed relation thereto when enabled for staking the mounted end cap to the magazine; said staking means being mounted for limited movement relative to said cap moving means; detecting means responsive to relative movement between said moving means and said staking means for detecting interference between the end cap and magazine prior to the staking of the end cap onto the magazine; and disabling means responsive to said detecting means for disabling said staking means when interference is detected.
Claim 3
Dependent Claim
14 words
The invention according to claim 1 wherein said detecting means comprises a fluidic sensor.
Claim 4
Dependent Claim
66 words
The invention according to claim 1 wherein said detecting means comprises a fluid passageway formed by said moving means and said staking means, said passageway being in a relatively fluid-tight condition when said moving and staking means are in a normal position, and in a fluid-leaking condition when relative movement occurs between said moving and staking means due to interference between the end cap and magazine.
Claim 5
Dependent Claim
63 words
The invention according to claim 3 wherein said moving means comprises a housing having an opening of a predetermined configuration, and said staking means comprises a member of a corresponding configuration slidably mounted within said opening, and said fluid passageway comprises a peripheral groove along the periphery of said opening which cooperates with said member for movement between said fluid-tight and fluid-leaking conditions.
Claim 6
Dependent Claim
178 words
The invention according to claim 1 wherein said moving means comprises a movable housing having an axial opening of a predetermined configuration; said staking means comprises staking fingers mounted within said opening for axial movement relative to said housing, an annular ring complementary to and slidably mounted within said opening and abutting said staking fingers, and a spring biasing said ring against said staking fingers; and said detecting means comprises a peripheral groove formed along the periphery of said opening in alignment with and having its open position blocked off by said ring to enclose said groove, a fluid inlet fluidly connected to said groove for subjecting fluid in said groove to a predetermined pressure, a fluid outlet fluidly connected to said groove, and a fluidic sensor fluidly connected to said fluid outlet for sensing the fluid pressure in said groove and adapted to actuate said disabling means when said pressure is changed from said predetermined value caused by movement of said ring out of blocking engagement with said groove upon interference between the end cap and magazine.
Claim 7
Dependent Claim
16 words
The invention according to claim 5 wherein said groove is of a substantially T-shaped cross section.
Claim 8
Dependent Claim
38 words
The invention according to claim 6 wherEin said groove is circular and comprises a manifold portion of a predetermined volume and a neck portion of a smaller volume fluidly connecting said manifold to the periphery of said opening.
