Specification of Letters Patent,
Patented Aug. 2'7, 1912.
Application filed June 7, 19 11. Serial No. 631,800.
To all whom it may concern 7 Be it known that I, OTTO L. HEINTZ, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented'new and useful Improvements in Methods of Producing Metallic Articles, of which the following isa specification.
This invention relates to a method for producing articles of metal such as jewelry, desk sets, &c.
The object of this invention is to produce such articles of superior quality and at reduced cost. i
In the accompanying drawings: Figure 1 is a plan view showing a metallic ornament produced in accordance with my invention. Fig. 2 is a sectional view, taken in line 22, Fig. 1.
Similar letters of reference indicate corresponding. parts throughout both views.-
In producing my improved metallic ornament a base a in the form of a plate or other desired shape is produced from a bronze composition containing from eighty to ninety five per cent, of copper and from a twenty to five per cent. of zinc. Upon this base is placed the ornamental facing b of silver, which may be of any desired shape or configuration. After the parts are thus assembled the sameare subjected to a temperature which is below the melting or fusing point of the base and, at or slightly above the fusing or melting point of the facing, whereby the facing is united with the base by fusing. In producing this fusing connection between the facing and base only that part of the facing next to the base melts sufficiently to make a fused joint with the base while the upper part of the facing remains unmelted, thereby avoiding spreading of the silver and distorting of the design of the ornamental facing. -This nonspreading of the silver is due to the presence of the zinc in the composition of the bronze base, the zinc causing the silver to begin its fusing flow on its backside contacting with the base at a lower temperature than would be possible if the base were made wholly or nearly so of copper. The presence of the zinc in the base also causes the under or inner side of the silver facing to fuse ormelt partly before the upper or outer side thereof is me1ted, thereby enabling the facing to become attached to the base by fusing'without permitting the facing to spread and distort the design. In the absence of any zinc in the base it would require a much higher temperature to bring the back of the silver facing to the fusing point, which increased temperature would produce the objectionable spreading of the silver and distortion of the design.
Upon heating the base and facing in the manner described'the zinc in the copper of the base rises to the surface and acts as a flux which aids in uniting the base and facing at a temperature just high enough to cause these parts to stick together securely. If less than five per cent. of zinc were present in the copper the heat required to bring the zinc to the surface would be so great that the silver facing would be liable to melt bodily and spread. If more than twenty per cent. of zinc is used in the copper the base would be too soft and therefore be liable to melt to such an extent by the time the silver facing has reached the required temperature that the facing would sink into the base and produce irregular and uneven work which would be unsa-lable and unacceptable to the trade.
Borax or other fluxing medium is preferably placed between the opposing surfaces of the base and facing so that the fusing action on the silver is quickened and aided in causing its inner or back side to fuseor melt partly before its outer side is melted, thereby insuring a goodjoint between the base and facing and further guarding against spreading of the facing.
Ornamental metal articles produced in accordance with my invention are not only strong but also cheap owing to the omission of any soldering operation, and the same are also of superior finish and quality.
