Thus far we have pursued the preparation ofthe material, or the manufacture of the nail-plate ; which branch occupies at least two-thirdsof the resources of the establishment. The nail-machines by which the plate is turned into thoseindispensable articles so small and trivial, yet soabsolutely necessary in every branch of industry,are situated in obscure parts of the works, and AMONG THE NAIL-MAKERS. 163. CUTTING AND TKIMAIING STAVEa but for their noisy clatter might be passed bythe visitor as of little consequence. There are onehundred and fifteen of these machines in ail, ofwhich number ten may be found in the imme-diate vicinity of the nail-plate train, and, as theyare all similar in construction, we will only oc-cupy ourselves with one of these. Our descrip-tion will be better understood on reference to theengraving. The lever-arm. A, is attached to dcutter working in the box, C, and is operated byan eccentric on the shaft which raises it at eachrevolution of the shaft. Meantime the cutter isdepressed and passes by the edge of the plane, d,on which the nail-plate is fed, and cuts off along tapering strip of the plate. This incipientnail is carried down a short distance to wherethe head is formed by means of the curved lever,B, the outer end of which is raised, while theinner end, striking upon the end of the strip,driv
