METALLIC STRUCTURAL UNIT 'Filed April 6. 1929 Sept. 15, 1931.`
Patented Sept. 15,v 1931 UNITEDA STATES PATENT OFFICE HERMANN VON FORSTER, OF NIEDERURSEL, NEAR FRANKFORT-ON-THE-MAIN, AND LUDWIG MOSER, F FRANKFQRT-ON-THE-MAIN, GERMANY METALLIC STRUCTURAL UNIT Application led April 6, 1929, Serial No.
Our invention relates to the problem of fastening and supporting eaves troughs, conductor pipes and like roof draining elements, and more especially such which are made of copper so as to effectively withstand corrosion through moisture.
Heretofore copper troughs and pipes for the purpose concerned where usually fastened and supported by devices .made of solid copper or of solid iron or steel, the latter in some cases having a relatively thin coating of tin or Zinc.
As a matter of fact both classes of fastening devices entail serious drawbacks: Those made of solid iron or steel and being relatively cheap and strong are subject to rapid corrosion through electro-decomposi tion accompanied by a concurrent still more serious corrosion of the respective copper made draining elements proper-While those fastening devices made of solid copper were rather expensive-*or else lacking in strength and subject to theft.
The object of this invention is to overcome the said drawbacks and to provide improved fastening devices for the specific purpose set forth which combine the desirable features of both classes of devices referred to above but excluding their disadvantages:
The invention aims at providing a fastening device which is relatively cheap to manufacture, strong as to its mechanical strength7 well resisting to corrosion and substantially safe against theft.
The nature and scope of this invention is briefly outlined in the appended claims and will be more fully understood by the fol- 353,257, and in Germany April 14, 1928.
solid copper which is much thicker than ever used and known before in connection with fastening devices of the class concerned.
As indicated in both figures the cores 10,
2O of the fastening devices have coatings of solid copper 11, Q1 of unusual thickness.
7e have obtained good results and we therefore propose to make the thickness of the copper coa ings 11, 21 about 20-30% of that of the total thickness.
lVe are aware that other articles of manufacture, parts of machinery etc. substantially different from those claimed may have been described in printed publications the copper coating of which serves various purposes including resistance against corrosion, and We wish to make it clear that our claim is limited to the class of fastening devices shown and combining the advantages set vforth above.
Whatwe claim is l. As a new article of manufacure, a device for fastening c opper rain spouts and gutters to a support comprising a core of rela tively hard metal having a high "tensile strengh as compared to copper, and a covering of copper applied to said device,said copper covering having a thickness of at least 10% of said core.
