By and by, as the heat in the furnaces increases, the smoke will diminish somewhat, though as long as the oil is inferior they will continue to emit a dirty cloud accompanied with deadly fumes and intense volumes of heat, which are forced out by the blast to a distance of several yards, making it impossible for the youth to get near enough to attend to his bars without having his arms and face scorched and burnt. The roof and walls, for a great distance around, are blackened with the soot. There is no mistaking the cause of it, though it is a favourite recommendation of the oil furnaces that they consume every particle of their vapour. When the oil is of a sufficiently good quality this actually happens; it is only when the fuel is cheap and bad that considerable unpleasantness arises.
Our entry to the shed was made through the large door in the north-west corner, near which the first oil furnace is situated. This furnace is attached to a new kind of forging machine conveniently named the “Ajax,” by reason of its great strength. Ajax was the name of two of the mighty ones who fought before Troy, but the manufacturer does not inform us whether the machine is named after Ajax, the son of Telamon, or he that was the son of Oileus, though perhaps the latter is intended. Standing alongside the oil furnace is the first of the drop-stamper’s forges, and next to that, in a line, are the three drop-stamps themselves. Opposite the Ajax is the foreman’s office — a two-storied building — and a little to one side, straight from the door, is a coal furnace, upon which is superimposed a large “loco” boiler. This reflects a tremendous heat all round, and, together with the furnaces and forges, makes that part of the shed, though near to the door, almost unbearably hot, so that it has come to be called “Hell Corner” by the workmen.
The line of hammers and furnaces is continued up the workshop to the far end under the wall. There also, fixed to the masonry, are the main shafting and pulleys, whirled round at a tremendous rate by the engine in the “lean-to” outside. At the end of the line stand the heavy steam-hammers and, under the wall outside, the blower house, containing machinery for forcing the air for the smiths’ fires. A huge stack of coal and coke is visible through the door at the other end. A small single fan is attached to the oil furnace with the Ajax in order to supply it with air. This travels at a high rate of speed and makes a loud roar, thereby adding to the confused din of the hammers and other machinery. Standing further out in the shed is a second row of smaller steam-hammers and forges with drills, saws, shears, pneumatic apparatus, other oil furnaces, and the American stamping-hammers with their trimmers and appliances. Beyond them is an open space reserved for future arrivals in the shape of manufacturing plant, and towards the south wall are two lines of powerful hydraulic machines and presses with furnaces and boilers attached for heating the plates of metal for punching and welding.
The Ajax machine operates by up-setting. It is worked by youths, one of whom heats the rods of metal, while the other sets them in the dies and presses the treadle that brings the machine head forward. As soon as the furnace is sufficiently hot fifteen or twenty bars are thrust through the brickwork in front of the forge, the lubricators are filled, the belt pulled over, and the work begins. The belts flap up and down on the pulleys with a loud noise, the cog-wheels rattle and clank, the “ram” travels backwards and forwards incessantly, clicking against the self-act, the furnace roars and the smoke and flames shoot out. When the bars are white-hot the assistant hands them along; his mate grips them and inserts them in the dies, then presses the treadle with his foot. Immediately the steel tools close up and the ram shoots forward; in about two seconds the operation is complete. Very often the water, running continually over the tools to keep them cool, becomes confined in the dies as they close. The heat of the iron converts it into steam, and, as the ram collects and forces the material, it explodes with a loud report, almost like that of a cannon. Showers of sparks and hot scale are blown in all directions, and if the operator is not careful to stand somewhat aside, his face and arms will be riddled with the tiny particles of shot-like metal ejected by the explosion. It is not uncommon to see his flesh covered with drops of blood from the accident. The bits of metal will adhere tightly underneath the skin, and must be removed with a needle, or otherwise remain till they work out of their own accord.
Both youths of the Ajax dwell in the town, and are known about the corner by the names of Harry and Sammy. Harry’s father was an infantryman, and Sammy’s parent served in the Navy. There is a little of the roving spirit about both of them — each possesses a share of the paternal characteristic. Harry’s father, however, is an invalid, and he is forced to stay at home and help keep him and his mother, otherwise he would long ago have bidden farewell to the shed, Ajax and all. Sammy, on the other hand, is free and unfettered, but though he has made many attempts to enter the Navy, they were all in vain. First, he was not sufficiently tall or broad in the chest, and later, when, after a course of exercises with dumb-bells, he was able to pass the examinations, he was refused on account of his teeth, which were badly decayed. This was a great disappointment to Samuel. He sulked about for several days afterwards, quarrelled and fought with his mate, and was generally inconsolable. The boys’ chargeman had to intervene as peacemaker and he comforted Sammy, who shed a few tears and finally became reconciled to the forge again, though he often defiantly affirmed that he would not be beaten, not he! He would go to Bristol and get a job aboard ship; he would not stop there in that hole all his life!
Both Sammy and Harry dress much alike, and they resemble each other in their habits. They are both nimble and strong, active, energetic, and high spirited. Both have commendable appetites, and they are especially fond of drinking tea. They have a passionate regard for sports, including boxing and football, but, over and above all this, they are hard workers; every day they are sure of a good sweating at the furnace and Ajax. Both wear football shirts — Sammy a green one and Harry a red and white — in the forge, and they have football boots on their feet. If you should turn out Sammy’s pockets you would be sure to find, among other things, half a packet of cigarettes, a pack of cards, a mouth organ, a knife, a comb, and a small portion of looking-glass. A great many of the town boys and young men carry a small mirror in their pockets, by the aid of which they comb and part their hair and study their physiognomies. At meal-times, as soon as the hooter sounds, they hasten to the nearest water-tap, give their faces a rough swill and, with the aid of a portion of looking-glass, examine them to make sure that they are free from the dust and soil of the smoky furnace.
Though the companions of Ajax work hard and perspire much they do not become very tired, apparently, for after the most severe exertions they are still ready to indulge in some sport or other, and run and play or wrestle and struggle with each other on their way down the yard. Arrived home they have their tea, wash and change, and come back to the crowded parts of the town to see and be seen and be moved on by the policeman, returning late home to bed. In the morning they will often be sullen and short-tempered. This invariably wears off as the day advances, however, and they will soon be up to the usual games, singing popular songs and imitating the comic actors at the theatre, where they delight to go once or twice a week.
Close behind the oil furnace, in a recess of the wall, is the fan that drives the blast for this part of the shed, supplying four forges altogether. The fan itself is of iron, enclosed in a stout cast-iron shell or case, and is driven from a countershaft half-way up to the main shafting. Multiplication takes place through this from the top pulley, and whereas the main shaft will make but one hundred and twenty revolutions a minute, the fan below will, in that space, spin round two thousand times. As the engine is running day and night, for more than twenty hours out of the twenty-four, the number of revolutions made by the fan will be over two millions daily. Although, viewed on paper, these figures appear high, yet, if you should stand near and watch the fan itself, it would seem incredible to you that it would require such a long time in which to complete them. The speed is terrific, and this you may know by the sound, without troubling to look at the gear. The rate of the belts, from the pulleys on to the countershaft, is a further proof of the tremendous velocity of the machine. Although strained very tight on the wheels they make a loud noise, flapping sharply all the while; one may easily gauge the speed of an engine by the sound of the belts alone. The fan itself, at normal times, emits a loud humming noise, like that of a threshing-machine, but when the speed of the engine increases through the relaxation of some other machinery, or the sudden rise of steam pressure in the boilers, it seems to swell with a dreadful fury, and assails the ear with a vicious and continuous hoo-hoo-hoo-hoo-hoo, HOO-HOO-HOO-HOO-HOO, like some savage beast ravenous for its prey. The oscillation of the fan is imparted to everything around. The very ground under your feet trembles, and if you should place your hand upon the outer shell, or on the wooden guard around it, you would experience something like an electric shock, strangely pleasant at first, but very soon necessitating the removal of your hand from the vicinity.
It is dangerous to meddle with the fan while it is in motion. A stout wooden guard is erected around it to prevent any object from coming into contact with the wheels or the interior. If a nut or rivet head should happen to fly and be caught in it, the shell would immediately burst. Very often excessive speed alone will cause a fan to explode. The effect is similar to that of a steam or gas explosion; the heavy cast-iron frame will be shattered to bits, and hurled to a great distance. I remember one in the smithy that exploded and blew up through the roof, making a huge rent. For safety’s sake the fans are often constructed underground in order to lessen the danger of explosion, if one should happen.
It is remarkable that while the pulley on the countershaft is travelling at a tremendous speed, so that the spokes are generally invisible, and there appears to be nothing but the rim and centre whirling round, if you look up quickly you will see one spoke quite plainly as it flies over, then it will be entirely lost to view with the rest. The space of time during which it is visible is exceedingly short — it could be no more than a fraction of a second — yet in that brief period the eye perceives it clearly and distinctly: it is something similar to taking a snapshot with a camera.
