Abstract
Abstract Capacitors are transferred one at a time by a vacuum feed chuck to one of a plurality of vacuum mounting heads which are moving along a definite path. As the capacitors are conveyed along the path, and exposed portion thereof to be coated is submerged to a prescribed depth in a liquid coating material. Next the vacuum mounting head is rotated to expose a further portion of the item to be coated in operating orientation, after which this portion then receives a coating as before. The freshly coated part is then passed through a lehr where the coating material is heat hardened. Finally, the capacitor is contacted by an arm as the vacuum head carrying it moves along the path, thereby disengaging it from the head and allowing it to drop into a receptacle.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
240 words
Apparatus for coating the ends of elongated articles, comprising: a conveyor turret including a plurality of vacuum chucks for indexing said articles through a loading station, at least one coating station, at least one heat treating station and an unloading station; each of said chucks including a notched face conforming to the configuration of an elongate section of the article received thereat; means feeding said articles to a transfer turret having a plurality of vacuum chucks; said turrets being disposed and synchronized in movement whereby opposed chucks are paired in cooperative association to effect transfer of said articles from the transfer turret chuck to the notched face on the conveyor turret chuck; means effecting said transfer of articles including valve means which at the time of common contact of an article with a pair of opposed chucks is adapted to connect the conveyor chuck to a vacuum source while simultaneously removing such vacuum from the transfer chuck; a non-planar guide plate overlying the path of conveyor chuck travel and contacting an end face of the article conveyed whereby to slide said article along the notched portion of the conveyor chuck to effect a predetermined alignment of the other end of said article with respect to the coating means at said coating station; and a coating means including a circumferentially grooved roller partially immersed in a pool of coating material and positioned to receive said other article end in said groove.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
25 words
Apparatus as in claim 1 including means disposed subsequent to the heating station and adapted to rotate each conveyor chuck thereby inverting the article carried.
Claim 4
Dependent Claim
33 words
Apparatus as in claim 2 including additional coating and heating stations disposed subsequent to the means to rotate and operatively associated with the conveyor turret whereby each end of said article Is coated.
Claim 5
Dependent Claim
41 words
Apparatus as in claim 1, in which said grooved roller is axially rotated during article coating in such direction that the portions of the roller immediately adjacent the article are moving in the same general direction as the article indexing movement.
Claim 6
Dependent Claim
38 words
Apparatus as in claim 1, in which the unloading station includes a fixedly mounted arm which engages a coated article as it is indexed through said unloading station and removes it from the associated conveyor turret vacuum chuck.
