mine and well developed prospect is today equipped with compressed air pneumatic drills and quite 4 frequently with other compressed air tools A very co common ninion compressed air tool is the drill sharpener of the mine blacksmith shop it is one of the most economic shop tools ever devised if worked to its best advantage the early models of drill sharpeners sharp eners have been replaced with modern designs so simple that the lowest priced labor on the job can call operate them they arel merely an application of die forging the heated steel is placed in a die while a dolly driven by an air hammer upsets up sets the steel in the e die every bit that comes out of the same die is exactly alike any boy who can place the steel in the machine and open the air throttle can make as many bits as the best blacksmith in the world the actual time required for upsetting a bit is about six seconds making new bits barge arge quarry bits and starters of course takes more time but with the average mine bits it is easily within the capacity ofa of a boy or a laborer to dress from four to tai six bits a ini minute nute if they are passed from the fire by a a heater boy tempering and heat treating of course is another step and should be this is best handled in specially designed sic ed furnaces I 1 can hear a protest from the old time blacksmiths because a boy a laborer beven or even a girl can sharpen more steel in an hour than the blacksmith could sharpen in a day nevertheless the day of specialization has brought out ut specialists and tools to perform i each step of the work the screw cutting machine is wholly handled by girls eirls a girl or a boy can feed a bolt rollin rolling nia machine chine that rolls threads on 42 bolts a minute that the blacksmith used to cut t with hand

forms s solicit advertisements and collect hect the bills today tile the linotype operator sets the type pe and others follow with the other steps the matter of sharpening b drill bits is a question of equipment and arrangement of 0 f the shop mine drill sharpener in shipyards when I 1 went into the shipyards during the war var I 1 aried carried with me many ideas that I 1 had gained around the Il lines es some of tile the work that was being done I 1 saw could be done ne with a drill sharpener and I 1 ordered one when was delivered at the blacksmith blacksill ith shop of tile the shipyard one the shop foreman half sarcastically sarcastic lly inquired are you goings g to sharpen mining steel here f no 0 o I 1 replied im going to use this machine for up etting g a lot of small things b that you buy outs outside ide make by and or make in the machine shop and to work up a abot at t f 1 scrap rap and waste material there the blacksmith h was some skepticism among pt those who had worked around the mine min minesa esC at achane me brou brought b the mine blacksmiths up to tile the machine aich ach looked aked to them like an old friend it singled out and to me every man in that great s shop hop who had eel a mine blacksmith and I 1 want to say here that for individuality individuality lit y loyalty operation cooperation co suggestions 6 ingenuity and resourcefulness the mine blacksmiths could give the city shop men cards and spades and beat them at most any work the first job that came up was an order for but toli towhead head drift bolts 32 inches long of 7 S inch rod the shop began 6 making 13 them b by y hand heading eight I 1 of these bolts an all hour was good work for a blacksmith and helper I 1 shoved a rush order through the tool room for a set of dies and a dolly the dies were simple merely a straight hole counter bored 18 1 8 inch the dolly was simply cupped to make a head of the right size similar in shape to the head of a carriage bolt the dies and dolly were made of ordinary cold rolled steel the emergency was so great that I 1 did not have time to for forge fore e out blanks from anything else the had them ready by noon saved on fist first fi st job picking out a young blacksmith who had bad worked in a ali mine ie shoeb shop I 1 gave him a heater boy to heat the rods in an all oil fire and pass them that afternoon the drill MV M 2 44 I 1 CA 1 ski Z wo PO plate I 1 sharpener headed bolts and the next day finished the job every head exactly alike at times we held a stop watch on the work sometimes the machine made 6 8 10 and even eve n 12 a minute ind and then the heater boy would lose a little time filling his furnace on light work of that kind we later tried two furnaces and let the heater have a helper to load and tend fires the drill sharpener saved on the first job it did and many thousands of bolts have since been headed with those same dies and dolly of cold rolled steel which are still in ill good condition although heading bolts with any shaped head is common practice around the mines I 1 never realized the possibilities ties of tile the drill sharpener until emergency in made ade me ine use it to produce a number dumber of th things ings I 1 had never dreamed of at the mine once there came a demand for wood screws commonly called lag lac screws 5 8 and 12 1 2 inches by 8 inches the war conditions had depleted the store supply and they were unobtainable so I 1 decided to make them on oil the drill sharpener I 1 had the die made with the threads and stamped the threads on oil the screw under the vertical hammer saving the work of cutting threads then I 1 thought how foolish I 1 had been for years for buying 6 lag screws at the mines when I 1 could have made them out of old stripped bolts hanging rods and old rods from the scrap pile at the rate of about five or six a minute even if I 1 hired a a laborer to do it on night shift and discharged the night watchman there was nothing d about it no tempering any boy could pick hot scraps of metal from a fire and lay them in the dies and step on the air next we wanted track spikes it was easy to square tip the rods under the vertical hammer or in the clamp and just as easy to put on a spike head as a bolt head and again I 1 thought 2 of 8 per pounds t that hat I 1 had paid for track spikes when I 1 could have produced 1000 worth from the scrap pile at tile the mine machines machined broad field of usefulness by this time the drill sharpener had become recognized as the best paying little machine in the shop and another one was ordered with the two machines we had opportunity for further development of its utility we made w 4 4 V 4 IR PAL plate ir II boiler patch bolts countersunk rivets where the length was greater area ter than the rivet machines would make rivet heaters tongs for handling hot rivets dyebo dye bo bolts its strap hinges large spikes for spiking heavy wharf planking etc etc As an experiment I 1 made some blank nuts from the steel of boiler plate and other small scrap in the shipyard we had too many nut hutsi always but around a mine it might be very well to know that the drill sharpener can produce them before you can send to town for a supply this same machine can be equipped with dies to male make ce it a shear or a punch with it ill you can cut out fish plates for light mine rail punch the holes make your own track bolts which should be threaded with the usual cut threads jt it is easy to chuck the die in a lathe or on a drill press or to make a rapid threading machine with a compressed ai air boring or drilling machine I 1 after all these little applications we found that we could make cold shuts chain links and put button heads and shanks on rungs for chain ladders ladde rs etc the usual pipe hangers U bolts ladder staples and the like are of course common productions of the drill Z sharpener but the greatest thing we accomplished was the making of ball stanchions for the hand rails it is common around mines to make hand rails from pipe fittings with floor flanges on shipboard they are made from one solid piece with balls upset through which holes are drilled or punched to carry the rail the balls and the foot were made upon the drill sharpener it was as easy to upset the middle balls as it is to collar a steel for the drill the only difficulty wag was that it re quiren more room to meet this emergency I 1 removed the hammer that came with one of the machines and con strutted ted a bracket in the rear on which I 1 mounted a piston 1 drill with a threefoot three foot f feed ced screw this permitted me to make auxiliary dies of most any length and back the ma chine as far back as was necessary see illustration plate no 1 the three ball stanchion was made with a ball on the foot just like the one on the top later the foot was flattened into shape under the vertical hammer the die used for making one shape of foot is visible in the lower right r hand corner of plate 2 by looking at these illustrations carefully you will see the easy possibility of working t up several tons of scrap drill steel into steel balls for ball and pebble mills at the rate of about five or six a minute and I 1 wonder why I 1 have bou bought ht forged steel balls when I 1 could have made them out of my scrap pile for one third the cost of the freight of course some one will lay awake all night trying to formulate a reason why all these things are impossible but they have been done and done with great economy we wei were confronted with skeptics and doubters from rom the first sugg suggestion estion we made but we delivered the goods and they are laying awake now trying td find out how we did it the most wordy opposition came from the s skeptics on the question of tempering to which I 1 replied the nia ma phinist who cuts a pinion gear temper it nor caseharden it he cuts it or shapes it and the end of his job it is carried to the heat treating treatie department and receives its required treatment there T hats all I 1 banc want you blacksmiths to do shape it when heat treatment is necessary on cold chisels chipping chappin
