Abstract

An automatic apparatus for soldering jump rings conventionally used in chain jewelry. The apparatus includes a fixture in which at least one and preferably a plurality of laterally oriented grooves are disposed in the upper face of a heat resistant fixture which in turn is adapted to move longitudinally with respect to a frame which supports the fixture. In addition to the laterally oriented grooves, at least one and preferably a pair of longitudinally oriented grooves are disposed in the face of the fixture in intersecting relation to said lateral grooves. Heating means including means for directing a pinpoint flame jet to each of the longitudinal grooves is fixedly positioned on the frame such that when the jewelry chain is placed in the laterally extending grooves with the jump ring or rings disposed in the area of intersection between the longitudinal and the lateral grooves, relative movement of the fixture with respect to the frame causes the jump rings to be moved progressively past such pinpoint flame jets so as to heat the same and accordingly accomplish the desired soldering action.

Dependent claims

Automatic soldering apparatus for soldering components of an elongated jewelry article such as the adjacent ends of split jump rings utilized to connect chain to opposite sides of an ornament and to a spring ring wherein it is desirable to avoid adversely thermally contacting those portions of the jewelry article disposed adjacent the ends being soldered comprising, a frame including longitudinally directed laterally spaced guides, a heat resistant fixture disposed between said guides, said fixture adapted for longitudinal movement relative to said frame and having a generally planar upper face in which at least one laterally extending article-receiving groove is disposed for receipt of said jewelry article to a fixed position relative to said fixture, at least one longitudinally oriented groove intersecting said lateral groove, said groove intersection adapted to receive one of said split rings to be soldered, heating means mounted on said frame for directing a narrow, high temperature flame jet into said longitudinal groove and means for longitudinally moving said fixture relative to said frame, whereby said split ring is momentarily contacted by said flame jet during movement of said fixture relative to said jet.
