PUTTING THE AIR TO WORK. One of the most interesting things in a modem industrial plant is the wider use of compressed air for all sorts of purposes. Not only the me chanical force of the escaping jet is used, but it is an efficient drier and, conversely, when combined with spray a moistener. For cleaning out-of-the way nooks nothing can equal it. It tempers steel, stirs mixing liquids and blows factory whistles. It is clean, and when it has done its work it is in nobody’s way. It makes the place where it is used a cooler, sweet er and more comfortable place to work in. Mr. Harry Franklin Porter, in one of a series of articles in “Fac tory” (Chicago, April), writes, in subtsance: “A jet of water is capable of cool ing or cleaning, but its action is lim ited to materials which will not be injured by moisture, and it requires provisions for drainage. Air, on the other hand, will clean or cool a batch of dough or a chunk of steel with equal facility. A steam jet, too, can accomplish many things by direct ac tion, but who wants to wrork around one? Air is obviously in a class by itself, for such purposes. In at least one machine shop, air jets are em ployed on cutting tools, in lieu of oil or soda water, to keep both tool and work cool. “Air, again, in a Uerman factory, has been found to solve the problem of graduated hardening of steel. By carefully spacing the nozzles the de gree of hardening may be graded quite accurately. “For reaching dirt and dust in the hidden recesses of machines and prod uct, nothing equals a blast of air from a well directed nozzle. Vacuum cleaners are all right for flat surfaces and hence excellent for floors, tables and benches, but it takes a jet with plenty of pressure behind it to re move oily particles and negotiate the irregularities of motors and machines. Dynamos and motors, for best results, and safety against fire, must be kept dean. How to dislodge and remove the particles which collect on the cores and windings w as a knotty prob lem until the air-jet was tried. “Textile mills, too, have of late adopted air-cleaning very generally. In no industry is the cleaning problem of greater moment. Lint generally is heavy from the fact that the atmos phf re of textile rooms is, or always should be somewhat humid. Hence, if blown downward, the lint gravitates directly to the floor. Many machines can be cleaned w'hile in motion, thus increasing the output efficiency.” When a mill is once “piped for air," other uses of it continually develop. For instance, in a textile mill, the air must be kept moist, and the air jet, combined with a water spray, has been found the best thing for the pur pose. This plan also promotes cool ing and ventilation. Stock is moist ened by the same device, using a coarser spray. Again: “Air is effective in removing not only solid particles, but undesirable liquid dirt as well. Close to the point of discharge, the force of an air-jet is so great, under even a moderate pressure, that jets will do the work of brushes, as in raising the nap on certain heavy fabrics and putting the finish on silk ribbons, or of buffing wheels as in polishing metal. In one plant an invisible screen is thus formed across a door opening, which must be kept unobstructed, to keep out flies. Men can easily pass, but winged insects might as .well try to get through a steel plate. “Again, air pressure is one of the best ways of quickly and thoroughly forcing the water out of boiler tubes. It is also an excellent means of test ng, not only boiler tubes for leaks, but any kind of piping. It searches out the minutest leaks, the location >i which will at once be apparent if he pipe is coated with soapy water. “Air is furthermore an aid to more rapid drying. In a varnish plant, air s introduced into the newly coopered jarrels, after they have been glued, to make the glue set faster. It is also ised to dry out the steel drums after washing. “In several cotton mills the yam, ifter it has been dyed, is dried by the same agency. “Vacuum drying, where applicable, ;, of course, more efficient than pres sure drying. It is, in fact, about the quickest known method. This principle s taken advantage of very largely m textile mills to secure rapid drying >f materials. A properly designed air ompressor can create whatever vac uum is needed about the plant, as well as supply air at pressure. “The agitation of liquids is another use to which the air jet principle has been successfully applied. Mixed paints, varnishes, and many chemical and dyeing solutions must be kept in constant agitation, or very thoroughly stirred by hand or mechanical means before drawing. A compressed air manifold in the bottom of the tank, | with orifices facing downward to pre (vent sediment entering and stopping | up the holes, is a most effective means of accomplishing this purpose. It can make the liquid fairly boil. “A blast of compressed air also is m excellent means of blowing the fac ,ory whistle, if you carry no steam at night or over holidays. If the air compressor is electrically driven, it •an be started and stopped automatic illy to replenish the air supply should l the whistle have to blow a long time. The United States Steel Corporation at Gary have a special compressed air whistle which they blow four times a day to call attention of all vforkmen to the subject of safety.”—Literary Digest.
