    Abstract: A method and apparatus are provided for soldering abutting ends of links of chains of precious metals. The soldering is accomplished by applying solder to the abutting ends, continuously feeding the chain onto a rotating surface such as a rotating table, heating the chain to melt the solder, and removing the chain from the table. The chain is fed at a slightly higher rate than the rational speed of the table to cause the links to be pushed into each other to avoid tensions from developing in said links during the heating step.

    Abstract: An apparatus for discontinuously and simultaneously soldering an ornamental chain on two locations and with recovery of the cores which hold the loops, comprises a reel (2) for winding and unwinding the chain to be soldered, a pair of rollers (3,4) for advancing the chain, a movable and rotating vice for carrying the chain to the soldering device. The latter comprises two flame injectors, arranged opposite one to the other and acting on the loops of the chain, a pair of vertically movable clamps for holding the chain during the soldering operation, in the two predetermined locations. Finally after the soldering operations, the cores are removed from the chain and are separately collected.

    Abstract: A heavy-duty chain link which constitutes a chain for use with vessels and the like. The link is fitted with a stud across the center thereof, which tends to prevent stretching and kinking of the link. Heat sources such as electron beams and plasma arcs fusion weld the abutting of two ends of the link, and the stud is wedged at at least one of its ends to said link by means of roots of weld beads provided by the heat sources. Such wedges lie at a right angle with the axis of the link for most effectively preventing the stretching and kinking of the link when it is subjected to a heavy load. A method of making this kind of stud chain link is disclosed also.
