Abstract
Abstract An article and more particularly a glassware gripping device constructed with opposed mating resiliently mounted gripper elements movably mounted with respect to each other and affording an inherent gripping force such that actuator applied forces may be substantially reduced. Additionally, the gripper elements per se of the device are of a modified configuration, i.e., feathered forwardly and rearwardly on their underside to enable their placement in close proximity with the concavity produced in a fluidized bed surface by article immersion.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
158 words
An article gripping device suitable for use in transferring glassware or the like and comprising: a pair of substantially parallel and laterally opposed movable bars having immovably affixed thereto a plurality of depending means that are spatially positioned along each of the bars for planar movement therewith; a connector assembly pivotally mounted to a frame support and interengaged with said bars such that the bars reciprocate laterally and longitudinally toward and away from one another responsive to the oscillatory movement of said connector assembly; said means including opposed gripper elements positioned and simultaneously movable with said bars in approximately the same plane both longitudinally and laterally toward and away from one another so that in at least one position of said bars the means and elements affixed to one are in juxtaposition and in gripping relationship with the means and elements affixed to the other; and actuator means engaged with said connector assembly to intermittently oscillate said assembly.
Claim 2
Dependent Claim
158 words
An article gripping device suitable for use in transferring glassware or the like and comprising: a pair of substantially parallel and laterally opposed movable bars having immovably affixed thereto a plurality of depending means that are spatially positioned along each of the bars for planar movement therewith; a connector assembly pivotally mounted to a frame support and interengaged with said bars such that the bars reciprocate laterally and longitudinally toward and away from one another responsive to the oscillatory movement of said connector assembly; said means including opposed gripper elements positioned and simultaneously movable with said bars in approximately the same plane both longitudinally and laterally toward and away from one another so that in at least one position of said bars the means and elements affixed to one are in juxtaposition and in gripping relationship with the means and elements affixed to the other; and actuator means engaged with said connector assembly to intermittently oscillate said assembly.
Claim 3
Dependent Claim
47 words
An article gripping device according to claim 1 wherein said depending means further includes relatively thin resilient members that immovably link together said gripper elements and said bars and at least one of the juxtaposed gripper elements has an article contacting surface having a substantially V-shaped configuration.
Claim 4
Dependent Claim
54 words
An article gripping device according to claim 2 wherein the other of the juxtaposed gripper elements incorporates an article contacting surface having a protruding abutment means adapted for alignment with a portion of said V-shaped configuration in at least one position of said parallel bar arrangement so as to firmly grip the article therebetween.
Claim 5
Dependent Claim
22 words
An article gripping device according to claim 2 wherein said gripper eleMents are mounted to the resilient members at one extremity thereof.
Claim 6
Dependent Claim
22 words
An article gripping device according to claim 2 wherein said gripper elements project in a substantially 90* orientation from said resilient members.
Claim 7
Dependent Claim
25 words
An article gripping device according to claim 5 wherein the undersides of said gripper elements are feathered both toward the forward and rear extremities thereof.
