Rupert, Mill Hall, Pa., assignor, by mesne assignments, to Sylvania Electric Products Inc., Wilmington, Del., a corporation of Delaware Application November 13, 1957, Serial No. 696,150
2 Claims. (Cl. 204299) The invention relates to an appliance for use in the coating of coiled objects. More specifically, the invention relates to the use of an appliance for suspending a number of spirally coiled Wires within a coating bath while coating the wires with an electrical insulating material.
In the past such wires have been coated, electrophoretically, by clamping the upper ends of the spirally coiled wires in a metallic spring clamp much like a spring paper binder clip, and immersing the wires in a bath of insulating material while passing an electric current through the bath, coiled wire and clamp. To entirely coat the coils, the lower part of clamp is immersed in the bath as well. Since the metal clamp is one electrode for the electric current it, too, iscovered with the insulating coating, necessitating cleaning of the clamp for the next batch of wires so that the current could pass through the wires and clamp.
It is an object of this invention to provide a device for supporting a number of coiled wires to receive such coating and in which the coating necessarily forming on the part of the device supporting the wires is automatically stripped off concurrent with removal of the coated wires from the device.
It is a further object of the invention to provide such a device with means to ensure supporting of the Wires in properly spaced relation.
It is yet another object of the invention to provide a holding device for the ends of coiled wires of such character as to accommodate a large number of spaced coils of wire in a small space.
These and other objects of the invention will become apparent upon consideration of the following specification when taken in conjunction with the accompanying drawing in which:
Fig. l is a perspective View of the holder.
Fig. 2 is a plan view thereof.
Fig. 3 is a view with the lower portion of the holder in section and taken along the line 33 of Fig. 2, the stripper plate being shown close to the metallic plate.
Fig. 4 is a similar view with a section taken on the line 44 of Fig. 2, the stripper plate being displaced from the metallic plate and in position after the coils had been stripped ofi.
Referring to the drawings in greater detail, at there is indicated a metallic post, as of aluminum, provided at its upper portion with a perforation in which is seated the jack 12 to encompass a spring or banana plug on a machine. The lower end of the post is reduced in diameter to form a neck 14 of circular or non-circular configuration on which is slidable a metallic pin retaining plate 16 having a central bore to slidably fit over the neck. Interconnecting the plate 16 and the post is an electric lead 18 having terminals screwed into the post and into the plate as indicated at 20 and 22. Affixed to the lower end of the post 10, as by screw 24 is the stripper 26. The pin retaining plate can be slid on the pock neck the limited distance between the stripper plate and the shoulder formed between the neck and the larger diametered portion of the post, good electrical connection being maintained between post and plate by the lead 18. ,The plate 16 has mounted therein a number of cylindrical metallic pins 28 with tapered ends, these being preferably arranged in some form of symmetrical array, as in concentric circles with any suitable number of circles and any suitable number of pins in a circle. The pins may be mounted in any desired manner in the plate, the preferred manner being by means of set screws 30 extending from the rim inwardly into engagement with the upper ends of the pins, the pins in different circles being staggered to facilitate being engaged by the screws. The pins project downwardly from the plate and extend through openings in the stripper 26. The stripper is made up of a guide 32 which is the member directly secured by screw 24 to the post and a wear plate 34 of hardened metal fastened to the guide 32, as by cap screws 36. The guide has openings 38 through which the pins 28 can pass very loosely, while the wear plate has openings 40 fitting tightly about the pins. In the retracted position of the plate 16, see Fig. 4, the conical ends of the pins lie substantially flush with the lower surface of the wear plate. In the projected pin position of the plate 16,
see Fig. 3, the pins extend a considerable distance below the wear plate to enable wire coils, such as coils 42, to be sprung over the ends of the pins.
After the coils have been mounted on the pins, the appliance is lowered, as by lowering of the banana plug supporting the post, dipping the entire coil, and the lower ends of the pins, in the coating bath. After electrophoretic coating, the appliance is elevated and the stripper 16 operated by hand or otherwise to pull the pins up through the wear plate to the positions shown in Fig. 4. Thereupon the coils 42 will be automatically removed from the pins and the wear plate will scrape from the surfaces of the pins any adherent coating material so that the pins may be clean enough to make good electrical connection with the next batch of wire coils to be coated.
What is claimed is:
' 1. A coating appliance comprising a stripper, a post extending from the upper face of the stripper and provided with an electric terminal, a metallic plate slidable on the post, a wired electrical connection between said terminal and metallic plate, metallic pins fixedly mounted in said plate extending substantially perpendicularly downwardly therefrom, said stripper plate having a member provided with perforations therein snugly slidably accommodating the pins, the pins in one position of the metallic plate extending below the stripper to receive coiled wires and in another position being retracted within the stripper plate to efiect stripping of the wires from off the pins.
2. A coating'appliance comprising a metallic'post, a jack serving as an electrical connector in the upper end of the post, a circular stripper fastened to the lower end of the post with the post central of the stripper, said post at its lower end being reduced in diameter to form a neck, a metallic pin retaining plate slidable on said neck and in wired electrical connection with the post, pins fastened to the retaining plate and adapted to extend through aligned holes in the stripper, said stripper at its bottom being provided with a surface of hardened metal with holes therein aligned with the pins and snugly engaging the same.
