The mechanic's tool bookWith practical rules and suggestions for use of machinists, iron-workers and others . it descends past the hole in which thewire is held. By making the several holes of dif-ferent sizes as many sizes of wire can be inserted,and if the larger holes be made near the shear-jointless force will be required to sever the wire than ifit were placed more distant. The use of the shearblades are in no way impaired by this arrange-ment for cutting sheet-metal. We have seen an arrangement for wire-cuttingattached to a lathe, and it consisted of a narrowblade of steel, made with appropriate cuttingedges and bolted transversely across the face-plate of the lathe, and this blade revolved againsta plate placed in front of it, and through this platethe wires to be cut were inserted. The distance WIRE-CUTTING. 153 of the cutting-blade from the face-plate to whichit was attached determined the length of the pieceof wire which was to be cut off. A cheap and efficient wire-cutter may be madeas shown in the cut, which consists of a steel forg-ing fastened perpendicularly to the bench by an. Fig. 34. extension of the lower part of the plate, a nutholding it firmly in place. The upper part of thebar has a number of holes drilled to receive thewire to be cut, and at the extreme upper portionthere is a hole to receive the bolt that forms thepivot upon which the cutting-blade is hung. Itis almost needless to add that the part where theholes are made must be nicely tempered. It willbe observed that the cutting-blade is made of a Tshape, and hung upon the pivot bolt in such amanner that when the handle is lowered the cut-ting edge of the pivoted end severs the wire, which 154 mechanics tool book. is thrust through any one of the holes in the gauge to determine the length of the wire canbe fixed by means of a screw in the lower portionof the plate. By making the cutter-blades of a T-form, if oneblade should become broken or injured the oppo-site blade can be used,
