operation by pressure, the pieces of wood or metal are removed, the
mouths are closed by making a fold in the top of the bags, and the
latter are then put back into the apparatus or into an ordinary press
and submitted to another squeezing.

To render the maneuvering of it easier, the apparatus has been given a
horizontal position.--_Revue Industrielle_.

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.
