Patented May 31-, 1938 UNITED STATES v SUPPORTING APPARATUS Arthur M. Wagner, Riverside, 11L, asaignor to Western Electric Company, Incorporated, New York, N; Y.,'a corporation of New York Application June 27, 1936, -Serial No. 87,671
This invention relates to article supporting apparatus, and moreparticularly to plating racks for holding articles during the electro-plating thereof.
5 An object of this invention is to provide an apparatus for supporting a plurality of articles under tension. t
In accordance with one embodiment of the invention a plurality of helical springs are mounted at one end of a rectangular rack, and each spring has a rod associated therewith to which one of a series of articles to be plated may be connected, bent wires serving to hold the remainder of each series of articles together and to the other end of the plating rack'whereby the spring will hold all of the series of articles associated therewith under tension to insure a good electrical contact between the articles and frame during the electro-deposition of a plating on the articles. 7
A better understanding of the invention may be had from a consideration of the following detailed description when considered in conjunction with the accompanying drawing, wherein Fig. 1 is a front elevational view of a plating rack embodying the invention, and
Fig. 2 is a sectional view taken on the lines 2-2.of Fig. 1 in the direction of the arrows.
Referring now to the drawing wherein like reference characters designate like parts throughout the several views, the numeral ll indicates generally a rectangular framework composed of uprights l2 and I2 and cross members and I5.
The upper ends of the uprights l2 and I3 are bent 35 as shown at I. and I! to form hangers by means of which the rack may be supported in a plating tank. Welded to the uprights l2 and II is a semi-circular handle I8 adapted for use when the plating rack is handled. v 40 Supported on the cross member I5 is a spring supporting framework designated generally by the numeral I! which may be easily'placed on the rack or removed therefrom and which comprises a'bracket Ill, L-shaped in cross section, a spacer 45 2iand a retaining'plate 22. The spacerf2l is substantially of the same thickness as the cross member l5, and when the spring supporting bracket I2 is in place upon the rectangular framework the spacer' 2| will restupon the cross mem- 50 her II, and the bracket '20 and retaining plate 22 will engage the left and right faces of the cross member l5, respectively, (Fig. 2) Suitably secured to the spring supporting framework is is a guide bar 23 which, when the spring sup- 55 porting framework is in place upon the rack H will engage left and right surfaces (Fig. 2') of the handle at its highestpoint between adjacent portions of the guide bar 23 which is bent over as shown at 24 to provide a substantially inverted U-shaped hook, thereby preventing the frame- 5 work I! from tilting on the cross member.
A plurality of spring guides 25, in the form of vertically extending rods are mounted upon the bracket 20, and" serve to position coil springs 26 which rest upon the bracket 20, and surround 10 the spring guide rods 25. A plurality of rods 21 are bent, as shown at 22, to surround the spring guide rods and engage the tops of the coil springs 26. The lower ends of these rods are passed through apertures in the bracket and are bent 15 over as shown at 29 at their lower extremity to engage in holes in articles to be plated. The articles to be plated may be strung together by means of bent wires or rods ill, and the bottom article of the series may be connected to the cross member II by a rod or wire it. v v
As will be apparent, the articles strung together by means of the wires 30 and secured to the cross member I by means of the wires it having the upper one of each'series thereof attached to the rod 21, will be held resiliently under spring pressure on the rack. In this manner the articles to be plated are supported upon the rack and. a good electrical connection between the 4 parts and the framework is assured, thereby ma- 30 terially aiding in the electro-plating of the articles. a
It will be noted that the springs 26 are-positioned some distance above the articles so that when the articles are plated the springs will not come in contact with the plating solution and will therefore be prevented from losing their tension by successive accumulations oi electrodeposited metal and/or by the hydrogen embrittlement normally associated with electro-pl'ating, 40
Although a specific type of article'has been illustrated and a specific type oi' structure has been shown for supporting the articles, it will be understood thatarticles of shape having apertures therein or other means, .whereby the rods 29 may be attached thereto and which are -.capable of being strung-bu a rack, might be held on the disclosed type of rack; Furthermore, minor modifications might be made in the structure of the rack without departing from the scope of the appended claim.
What is claimed is:
An article supporting-apparatuscomprising a framework, a cross member on said framework,
a handle extending from said framework, a spring supporting bracket removably positioned on said to each spring and normally urged away from cross member, a U-shaped member carried by I said cross members by its associated spring for said bracket for engaging said handle to position supporting a plurality of interconnected articles said bracket on the framework, a second cross under tension between said cross members.
5 member on said framework, a plurality of springs mounted on said bracket, and a rod individual ARTHUR M. WAGNER.
