Model shearing machine for iron plates
The model shows a type of machine patented in 1843 by G. B. Thorneycroft for shearing large iron plates.
The lower blade is fixed and the upper one slides in guides formed in side standards which also hold the bearings of a horizontal shaft. Three cams on this shaft force the blade downwards and two light eccentrics lift it for the next stroke. The shaft has square ends and was probably driven by a cast-iron breaking-shaft that would fail if the cut attempted were too heavy.
