Tn inverin 4 P arimcut B B F The trade of Operating Engineering as taught at William- son constitutes a very practical and theoretical course of study. The first six months of the Freshman year the apprentice spends in the machine shop where he is given a brief, but thorough course in elementary exercises, including plain chip- ping, filing and fitting, belt lacing, forge work, babbiting and scraping boxes, and the reading of micrometers, outside and inside calipers, vernier calipers, and the speed indicator. He also acquires a full knowledge of the setting up of work on the lathe, drill press, shaper, planer, and the operation of the same. All this is accompanied by a correlated course of study. In the latter half of the year the student goes to the power plant. Here he learns the names of the tools used in the trade and the use of same, and has charge of issuing the supplies. When the apprentice becomes a Junior, he is taken on the operating staff of the school power plant as an assistant. He now makes daily inspection of the school plant, i. e., pump in- spection, inspection of the water, lighting and heating fixtures, and helps make repairs for the upkeep and maintenance of the same. He also gets a thorough line of boiler repair work, in- cluding that disagreeable but knowledge-gaining test of clean- ing the boilers, which also includes the removing of old and re- placing of new tubes, and the rolling of the same, the setting of safety valves and many minor details. Shop talks, notes, and the studv of a text book with a quiz every month conclude this work. The student now ontcrs upon the last year. He is now a member of the operating staff and is on duty in the engine room twelve hours a day for a period of one week. Each member of the Senior Engfncering Class has this duty to perform on an average of once every two months. While on duty 24 VERNON L RUPP lnslruclor

51112 elllianliine 4 apartment This outline will give the reader a good idea of the way in which the machine trade is taught at Williamson. The course is divided into three years, Freshman, Junior, and Senior years. During the Freshman and Junior years, the apprentice spends four hours daily in shop. Of this time a limited amount is spent in shop talks over work covered. The senior has eight hours a day in shop and has shop talks for two uours on :saturday mornings. In connection with this, the stuay of strength of materials and steam is taken up two evenings a WEEK. The greater part of the first year is devoted to exercises in plain chipping, fiat filing, and elementary work on lathe, shaper, and drill press. A large amount of forge work is accomplished in the first year, which includes the making of broad and cape chisels and side tools. . In the second year the apprentice receives more advanceci work on the lathe, including inside boring and threading, taper turning and boring, the cutting of multiple threads by various methods, eccentric work, brass work, etc. He also receives a good knowledge of the elementary methods of doing work on planer, slotter, shaper, boring mill, grinder, and miller. The senior year develops in the apprentice speed along with accuracy. The senior gains knowledge in annealing, open fire hardening, and tempering and case hardening. Advanced bench A- LEONARD LOGAN and floor work which embraces assembling of machinery and Imffudof general jobbing are now given in order to give the apprentice confidence and the ability to plan work ahead. The shop is large and well equipped and contains an excellent tool room. The forge room is large enough to meet all requirements and part of the shop is used for automobile repair work. In closing this account, we, the machinist class of 1920, are proud to be graduates of a school where such a wonderful opportunity exists, and we wish to express our earnest appreciation and esteem to our instructor, Mr. Leonard Logan, for his valuable instruction.
