Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
118 words
For use in a packaging machine, double-jaw gripping means comprising first and second jaws, control means for causing relative movement of said jaws in a common plane between an open and a closed position, means for selectively raising said first jaw relative to said second jaw and out of said common plane of the jaws, and means restricting the raising of said first jaw except in the open position of the jaws, said control means for causing relative movement of the jaws includes an elongated control member having a romote end mounting said first jaw, said means for selectively raising said first jaw including a hinged joint in said control member inward of the jaw mounting remote end.
Claim 2
Dependent Claim
118 words
For use in a packaging machine, double-jaw gripping means comprising first and second jaws, control means for causing relative movement of said jaws in a common plane between an open and a closed position, means for selectively raising said first jaw relative to said second jaw and out of said common plane of the jaws, and means restricting the raising of said first jaw except in the open position of the jaws, said control means for causing relative movement of the jaws includes an elongated control member having a romote end mounting said first jaw, said means for selectively raising said first jaw including a hinged joint in said control member inward of the jaw mounting remote end.
Claim 3
Dependent Claim
48 words
The gripping means of claim 1 wherein the means for selectively raising said first jaw further includes spring means at said hinge joint biasing the outer portion of the control member, between the hinge joint and the romote end, upward out of the common plane of the jaws.
Claim 4
Dependent Claim
105 words
The gripping means of claim 2 including a second elongated control member with a remote end mounting said second jaw, said means restricting the raising of said first jaw being mounted on said second jaw and selectively movable between a first position overlying the portion of the first control member between the hinge joint and the remote end thereof to maintain the jaws in a common plane against the biasing force of the spring means, and a second retracted position to the opposite side of the hinged joint, allowing an unobstructed raising of the remote end of the first control member by said spring means.
Claim 5
Dependent Claim
42 words
The gripping means of claim 3 wherein the length of the portion of the first control member between the hinged joint and the remote end thereof is substantially equal to the maximum space in between the jaws in the open position thereof.
Claim 6
Dependent Claim
95 words
For use in a packaging machine, double-jaw gripping means comprising first and second jaws, control means for causing relative movement of said jaws in a common horizontal plane between an open and a closed position for selective gripping engagement with and disengagement from a package end positioned therebetween, means for selectively raising said first jaw relative to said second jaw, out of said common horizontal plane of the jaws and into general vertical alignment with said second jaw, and means restricting the raising of said first jaw except in the open position of the jaws.
Claim 7
Dependent Claim
95 words
For use in a packaging machine, double-jaw gripping means comprising first and second jaws, control means for causing relative movement of said jaws in a common horizontal plane between an open and a closed position for selective gripping engagement with and disengagement from a package end positioned therebetween, means for selectively raising said first jaw relative to said second jaw, out of said common horizontal plane of the jaws and into general vertical alignment with said second jaw, and means restricting the raising of said first jaw except in the open position of the jaws.
