Letters .Patent No. 65,557, dated June 11, 1867.

IMPROVED TOOL-FOR CUTTING WIRES.

TO ALL PERSONS TO WHOMTHESE PEESENTS SHALL COME:

Be it known that I, WILLIAM H. FLINN, of Nashua, in the county of Hillsboro, and State of New Hampshire, have invented au improved Rod orWire-Cutting Machine; and do hereby declare the saure to be fully described in the following specification, and represented in the accompanying drawings, oi' Which- Figure 1 is a side elevation. i

Figure 2, a vertical and longitudinal section.

Figure 3 is a transverse section; and f Figure 4 is a horizontal section of it, this latter section being-taken through two holes of its cutter-plates.

My present invention is au iuiprovelnent in wire-cutters of the kind mentioned and described in Letters Patent No. 545,520, granted to me on the eighth dayl of MayA. D. 1866. Instead of the movable cutter-plate being made to revolve as it does in my patented article, it and its case are so changed in form that the movable die-plate, when moved, slides rectilinearly in the case. The principle of invention, so far as the application of the die-plate and its case is concerned, is the same in my present article as in that so patented.

y My improvement consists in arranging each pair of the cutting holes or orices of the two cutter-plates obliquely to the' faces or touching sides of such plates, instead of at right angles therewith, as they have heretofore been arranged. Each hole of the pair must of necessity have a diameter somewhat greater than that oi"v the rod or piece of Wire to be cut by them, otherwise it would not be an easy matter to introduce ,the said rod or piece ofwire into and through them. Under such circumstances it has been found that as soonas the holes are brought to bear on the Wire, they will throw it intoa'position more or less oblique to the touching faces of the two plates. The consequence is that when the wire o r rod is cut o, its end instead of being eut at right angles to the axis of the Wire or rod will be more or less oblique thereto. To obviate this diiiiculty, I arrange the pair of holes of the cutting-plates obliquely to the touching i'aces of the two plates, and at the proper angles-therel with to cause the wire while being cut to stand at right angles with the two plates.A i In the drawings, A denotes the ease, which is open :tt-its upper end, and is provided with elongated chamber, a, and an opening, b, extending therefrom through one sideof the case. A steel plate, B, slides into the case and rests against a spring, C, arranged within it in the case as represented. A lever, D, provided with a. cam, b', isarrangcd on the upperpart o f the case, and so as to 4be capable of being turned on a fulcrum or pin, @going through the case transversely. A series of holes, d al d, is bored through the plate B and the back plate e of the case, each hole in one plate having a fellow hole in` the other as represented, and the two are arranged obliquely to the faces of the plate in manner as. exhibited in the drawings. The case has a projection or ear,f, extending from it, such ear, when introduced between and held fast by the jaws of a vise, serving to retain the case in one fixed position so as to enable a person to work the lever so as to move the movable plate and cut o a wire or rod by the machine.

I claim my. improved wire or rod-cutter, made as described, viz, with cach cutting hole of each pair of such holes of the plates B and e arranged obliquely to the touching faces of such plates, substantially as and for the purpose as hereinbefore specied. i i
