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.

patternmaking gaeparinwnt Patternmaking, ranking among the important trades in the commercial world, is one of the six trades taught at Williamson. This trade requires accuracy of dimensions, skill in construction, and last, but by no means least, neatness. Patternmaking, as taught at Williamson, teaches the young man the theory of the trade and at the same time teaches him to apply the theory in a practical way. This makes the Williamson graduate highly proficient in his trade and gives him a good start towards a steady climb up the ladder to success. Our shop is large and well lighted and ventilated. The benches are placed at one end of the shop and the machinery at the other. The machinery consists of a circular saw, band saw, planer, jointer, two large belt-driven lathes, three small belt- driven lathes, a sander, and a tool grinder. When the student is starting his trade he is given some simple, elementary joinery exercises, which teach him the use of his tools. These exercises carry him through several months when he is ready to begin making plain patterns. This covers his work in the Freshman year. Then the student's work becomes slightly more complicated as he learns better the use of his tools and the reading of blue prints. In his Junior year he advances to segmental work which I includes ladles, blank gear wheels, and parted pulley Wheels. In I this year he is also taught box construction and lagging. These NATHAN J' TOBQAS patterns also introduce some simple core box construction. lnfffucfof i The student now starts his third and last year and it is i during this period that he constructs the most complicated pat- terns. Many of these ane patterns of parts of machines used throughout the shops and are often sent to the foundry, cast, finished up in the machine shop, and used in repairing machines or in making entirely new machines. During his Senior y ar the student in patternmaking also receives a short course in molding. This teaches him the real use nd value of draft and allowance for shrinkage of well constructed patterns. In closing, I wish to extend, in behalf of the patternmaking section of 1920 Class, to our instruc- tor, Mr. N. J. Tobias, ou many thanks and deep appreciation for his thorough instruction and increas- ing efforts to give us a sltart in life. He has done his part well and the future lies in our own hands. May we achieve the success We hope for. GEORGE A. WILSON.
