Show WIRE NAIL MAKING A derman in rapidly growing in the united states ono one of tins rapidly growing industries of tile the world but of coin comparativo lye ly recent origin Is ia tile manufacture of wire nails the business originated in germany and was only introduced into the united states about forty years ago a 00 hivo for a 1 number of years been established in pittsburgh ani ii and the industry sinca has gradually moved westward thero are two establishments in indiana the birg largest cst bein being in indianapolis the other wis was started at greencastle Grcen Green castlo castle during the pa past s t year steel wire nails have grown in in popularity because of their superior qualities of strength anti and toughness their manufacture is almost entirely a different diner from that of the ordinary cut nall nail there is no furnace work required anti and heavy machinery is not necess necessary alT roc for making wire nails the best quality of bessemer steel rods or wire is it usually employed employ ed the wire is made specially for the purpose and comes to the in large coils the first stop step in making a nail out of these coils is to plunge 0 them for two or three minutes in largo large vats cont containing con tuning a fluid the principal ingredient 1 of which is dilute sulphuric acal this action IS is MIMI necessary sar to clean the wire and better lit fit it for drawing the coils coll sare ire next cle cleaned anCL by dipping them into tanks of puro pure water and they ahre are then removed to the drying room this room is heated to 1 high hiah cle degroe cleree ree of temperature by Int moans lails of steam coils and tile tho wire is ia soon dried the wire before it cin can be properly drawn must bo be given the ri right lit temper and for this purpose sifter after it has boon been dried d it is removed to tho the an annealing nealin ovens where a uniform ligat heat is applied that softens it to the required drawing dra wint temper once in ill the drawing room tho the wire is reeled on oil cylinders placed near the reducing dies the dies are of steel and its usually U three or four sizes smaller than the wire the die is opened and the wira wire the free end is then attached to another cylinder moved by machinery which draws the wires through the dio die and again 0 rods reels it this process is continued through smaller dies until the required fineness finc is reached before it is run through the die however provision is made for bri brightening the wire for tin this s purpose it is given lvell a bath lit in lime water anil and the bodt costing im of lime which then adheres operates its as a polisher while the wire is bein being drawn 1111 through h the die the wire is now really Q f orl anto nails and is removed to the nailing room the coils are again 0 placed upon reels preparatory to connecting them with the ho nall ing machine which is altogether self acting the end of tho the wire is automatically mati cally fed into a 1 tic dio which cloan closing upon it ser secrates rates it and holds it momen harily while a rod hammer aati a piston hits a small exposed portion odthe of the wire and flattens ll attens it out into the head As the hammer withdraws tho the lie die separates sope sepe slightly allowing th alio e wire to piss pass through the lon th of a nail when a pair of small beveled chisels corning coming together 0 behind the lie die both point and cut off the nail the average capaci capacity t 3 of a nail machine is three hundred per minute and one man mail with a helper can call operate from four to nine the last stage in ill completing tile nall nail is to give it a further and finer polish and this is accomplished by putting the nails into in an iron lined cylinder which revolves revolve horizontally in revolving the nails ire are rolled from side to side and tho the abrasion which thus gives them the requisite polish to absorb the oil which may ila ha e adhered to tile the wire while passing through the machinery in lit the process of becoming nails a small emall quantity of sawdust is thrown into the cylinder indianapolis journal |
