Ebook Foundry Moulding Machines and Pattern Equipment

Uring the past years marvelous advances have been made in the amount of production obtained from the daily efforts of man. This is true not only in the industrial establishments, but is true in practically all walks of life, and especially does this fact stand forth in our home life, transportation, trucking, farm ing, merchandising, and in the industrial arts; it is evident in the steel mills, machine shop, pattern shop, and in some few foundries, especially those foundries engaged in the manufacture of automobile castings. The increased production that is obtain able in these and many other lines of daily activities, has been brought about by the utilization and application of scientific knowledge, engineering principles and mechanical appliances. This is a mechanical age. The hard, drudging, physical effort is being taken out of labor. Labor is now, in nearly all instances, being performed by the pulling of a lever, or the press ing of a button. The farm life is easy; plowing is performed by power, the wheelbarrow has become a truck, the Japanese jinrikisha an automobile, the hammer and chisel is replaced by a lathe and planer; but to the foundry in general these contrasts will not apply, as the moulding, in some plants, is still being performed in the same manner as it has been for centuries past. The mould is still made in the old — style wood ?ask, hand-rammed by the same old laborious method, and very little accomplished at the day's close. Instead of being fresh and vigorous, the man is all tired out, the production small, and in many cases the cast ings defective.
