Gripping type compound applying chuck assembly

Claim 2

A chuck assembly for gripping a cap during application of sealing compound comprising: a pad having magnetic means for attracting a metallic cap, a rotatable shaft fastened to the center of said pad, a rotatable housing slidably mounted on said shaft, supporting means mounted on said housing on the side of said housing toward said pad, spring means for biasing said rotatable housing toward said pad, pivot means for moving said rotatable housing toward and away from said pad, a plurality of gripping means for gripping a cap between them, each comprising an arm connected to a jaw and a pivot means supporting said arm and jaw and mounted on said supporting means.

Claim 3

A chuck assembly for gripping a cap during application of sealing compound as set forth in claim 1 in which said pad comprises: a thick disc having a flattish top and rounded sides.

Claim 4

A chuck assembly for gripping a cap during application of sealing compound as set forth in claim 1 in which said Gripping means comprises: a single element extending from said pivot means toward the shaft, an arm extending from said single element toward the shaft, a jaw extending upward from said single element and adjacent said pad whereby said jaws and said pad form a shaped member for holding a relatively deep container cap.

Claim 5

A chuck assembly for gripping a cap during application of sealing compound as set forth in claim 1 further comprising: an elastomeric means mounted on said pad between said pad and said rotatable housing whereby when said pad and said housing come close together said elastomeric means presses against said arms and causes said jaws to approach each other.

Claim 6

A chuck assembly for gripping a cap during application of sealing compound as set forth in claim 1 in which said supporting means comprises: stud means mounted at each side of said gripping means, and being mounted a distance from the shaft greater than the distance between the shaft and the periphery of the pad whereby the length of each arm at least equals the distance from the shaft to the periphery of the pad.

Claim 7

A chuck assembly for gripping a cap during application of sealing compound as set forth in claim 5 further comprising: an elastomeric means mounted on said pad between said pad and said arm of said gripping means whereby when said housing is moved toward said pad then each said arm impinges on said elastomeric means and each said jaw is urged inward toward said cap.

Claim 8

A chuck assembly for holding a cap during application of sealing compound to the interior of the cap comprising: a shaft having a first and a second end, a pad means for holding a cap and fastened to said first end of said shaft, a rotatable housing mounted for rotation about said shaft, a supporting means mounted on said rotatable housing, pivot means on the side of said housing for moving said rotatable housing toward or away from said pad means, a spring for continually urging said rotatable housing in the direction of said pad means, a gripping assembly comprising jaw means for gripping said cap, arm means integral with said jaw means for moving said jaw means into gripping engagement with said cap and being oriented in a plane extending between said pad and said housing, fulcrum means mounted on said supporting means for providing a fulcrum point for said integral jaw and arms, and elastomeric means mounted on the bottom of said pad means for pressing against said arm means to cause said jaw means to grip said cap.

Claim 9

A chuck assembly for holding a cap during application of sealing compound to the interior of the cap comprising: a shaft having a first and a second end, a pad means for holding a cap and fastened to said first end of said shaft, a rotatable housing mounted for rotation about said shaft, a supporting means mounted on said rotatable housing, pivot means on the side of said housing for moving said rotatable housing toward or away from said pad means, a spring for continually urging said rotatable housing in the direction of said pad means, a gripping assembly comprising jaw means for gripping said cap, arm means integral with said jaw means for moving said jaw means into gripping engagement with said cap and being oriented in a plane extending between said pad and said housing, fulcrum means mounted on said supporting means for providing a fulcrum point for said integral jaw and arms, and elastomeric means mounted on the bottom of said pad means for pressing against said arm means to cause said jaw means to grip said cap.

Claim 10

A chuck assembly for holding a cap during application of sealing compound to the interior of said cap as set forth in claim 7 in which said fulcrum arm and jaw means comprises; a plurality of fulcrum bearing means mounted on said supporting means, and arm and jaw means mounted at each said fulcrum bearing means whereby when said supporting means is urged upwardly the upper surface of said arm impinges against the lower surface of said pad means and urges said jaw means toward said cap to hold said cap firmly in said jaws.

Claim 11

A chuck assembly for holding a cap during application of sealing compound to the interior of said cap as set forth in claim 7 in which said elastomeric means comprises: an elastomeric ring mounted on the bottom of said pad whereby when said rotatable housing is urged toward said pad means said arm strikes said pad and said jaw is urged inward toward the center of said pad.

Claim 12

A chuck assembly for holding a cap during application of sealing compound to the interior of the cap as set forth in claim 7 in which said pivot means for moving said rotatable housing comprises: paired pivot means mounted on opposing sides of said rotatable housing for cooperating with an actuating means to cause said rotatable housing to slide toward and away from said pad.

Claim 13

A chuck assembly for holding a cap during application of sealing compound to the interior of the cap as set forth in Claim 7 in which said supporting means comprises: a plurality of studs each having a fulcrum means for positioning each of said arm means between said housing and said pad and each said jaw means in position to grip said cap when said housing is moved toward said pad.

Claim 14

A chuck assembly for holding a cap during application of sealing compound to the interior of the cap as set forth in claim 7 in which said pivot means comprises: a pin secured in said supporting means, and said arm comprises, an elongate member of sufficient mass that when said chuck assembly is rotated the arms tend to move outwardly under the influence of centrifugal force.
