Pat. application Ser. No. 440,410, entitled ELECTROCOATING, and represents an improvement to the hanger assembly described and claimed in the pending Koch et al. US. Pat. application Ser. No. 742,246, now US. Pat. No. 3,607,711 entitled ELECTROCOATING EQUIPMENT. In the arrangement of the aforesaid former pending patent application, the article being coated, the hanger for the article being coated, and the tank are at the same electrical polarity, i.e., at ground potential, where electrodes disposed within the tank and mounted in planes substantially parallel to the side walls of the tank are at an opposite electrical polarity.
In the arrangement of the aforesaid latter pending patent application, the use of a series of bus springs is taught in operative engagement with a moving conveyor which passes therebetween. Although such general arrangement has proven satisfactory, the invention herein serves as an improvement to the results already available. In this connection, various arrangements are provided to secure the desired wiping action, and, additionally, electrical insulators have been included, with the overall result of lower system resistance.
A better understanding of the invention will become more apparent from the following description, taken in conjunction with the accompanying drawing, wherein FIG. 1 is a top plan view, partly fragmentary, showing the invention in combination with a conveyor installation;
FIG. 2 is a view in end elevation, partly in vertical section, showing further details of the invention embodiment of FIG.
FIG. 3 is of a fragmentary view in end elevation, showing the invention in combination with an extended H hanger attachment;
FIG. 4 is a fragmentary view in end elevation showing the invention in combination with a C hanger attachment;
FIG. 5 is a fragmentary view showing the invention in combination with a sleeve on a hanger;
FIG. 6 is a fragmentary view of the invention showing wiping action on a brass nut and bolt mounted on an I-I" hanger attachment; and,
FIG. 7 is a fragmentary view in end elevation showing the invention in combination with an "H" hanger attachment and employing insulations means.
For the purposes of promoting an understanding of the principles of the invention, reference will now be made to the embodiments illustrated in the drawing and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended, such alternations and further modifications in the illustrated devices, and such further applications of the principles of the invention as illustrated therein being contemplated as would normally occur to one skilled in the art to which the invention relates.
Referring now to FIGS. 1 and 2, the invention is shown in combination with a hanger assembly 12 for a typical conveyor installation. In this regard, a supporting member 14, such as an l-beam, for example, serves as a support for wheels 12a forming part ofthe hanger assembly 12.
The hanger assembly 12 includes arms 1211 between the free ends of which is positioned a hanger attachment 120. The part to be coated is hung onto a hanger depending from the hanger attachment 12c, where, it should be understood, such hanger attachment 120 may be either an I-I" type, an extended H type, or a C" type. The hanger assembly 12 is moved along its desired path of travel through a drive chain 12d, the latter having a series of interconnected links.
In use, a series of bus springs or wipers 22 are spaced in a close relationship, as shown in FIG. 1, on opposite sides of the conveyor for a length equal to, at least, the size of the coating tank and in the direction of movement of the work. While the desired ground electrical potential is automatic and positively achieved, as in the aforementioned pending Koch et al., patent application entitled ELECTROCOATING EQUIPMENT, the invention herein represents an improvement in operation because of lower system resistance.
FIG. 3 shows another area for the desired wiping action. In this connection, the hanger assembly 12 employs an extended H" hanger attachment 12e, where the wipers 22 engage opposite surfaces 12c thereof. FIG. 4 shows wiping action on the part of wipers 22 on opposite side portions of a C" hanger attachment 12f. As should be evident, the C" hanger attachment 12f includes an opening 12f for receiving the hanger for the part under process. FIG. 5 shows still a further embodiment of the invention where, in this instance, wiping action is achieved from wipers 22 in engagement with a sleeve 25a disposed on a hanger 25 for the part, such hanger 25 being mounted on a cross bolt 25b positioned either on an H" hanger attachment or an extended H hanger attachment. In still a further invention embodiment, the sleeve 25a may be omitted, with wiping action being directly on the hanger 25.
FIG. 6 shows wiping action on a brass or steel nut and bolt combination 30 which extend through an I-I" or an extended H attachment. As evident, the nut and bolt combination 30 mounts hanger 25 onto which the part under process is carried. FIG. 7 shows a structure similar to the structure of FIG. 6, but, in this instance, the nut and bolt combination 30 is isolated from the H or extended H" attachment through members 27, the latter being made from teflon or di-electric material which takes heat and also serves such purposes of isolation. In the preceding invention embodiments, the same reference numeral has been applied, where appropriate, for clarity of presentation.
Accordingly, the invention herein, through various improvements, serves to make for more efficient system operation and, obviously, provides versatility as to hanger attachments and the like. Moreover, galling of the metal wheels of the hanger assembly has been minimized. The invention may, of course, be further refined to combine certain of the embodiments described above and shown in the drawing. Thus, the latitude of use is an important advantage.
