STEEL CHAINS WITHOUT WELDING.
We take the following description, together with the illustrations, of a method and machine for making steel chain without welding, from our valued contemporary, Le Genie Civil, of Paris:
When we regard an ordinary oval-linked chain endwise, it presents itself in the form of a metal cross, and it was this that gave the cue to M. Oury, of the Government Arsenals, to construct chain without welding. By a series of matrices and punches, etc., he contrives, with small loss of metal, to model a chain out of cross-shaped steel bar.
Steel is the better material for such usage, from its homogeneity, both as to composition and strength.
Referring to the plate below, Figs. 1 to 10 explain the successive steps from the bar to the finished chain.
Fig. 1 shows in plan and section the steel bar, whose length may be some 40 feet, and which would make a chain say 50 feet long. The shape of the bar presents no difficulties in the way of rolling.
