48 University of Illinois. lowing this is a course of practice in fitting and finishing, in which calipers, rules, etc., are introduced, and many of the various fittings employed in machinery are produced. Previous to the shop work, drawings of the pieces are made by the student, and the exact thing to be done is indicated; thus mistakes are avoided and practice facilitated. The designing of such machine elements as pulleys, journal boxes, cranks, stuffing boxes, etc., cultivates a knowledge of proportion, and of its proper representation on paper. This course of elementary practice fits the student for the advanced shop practice in designing and construction of complete machines undertaken later in the course. TECHNICAL STUDIES. Kinematics and Principles of Mechanism.—Relative motion of points in a system of connected pieces; motion independent of force; velocity ratio; investigation of motion of elementary parts of machines, as friction and non-circular wheels in rolling contact, cams and curves in sliding cantact; gear teeth; gearing chains; escapements; link work. Prime Movers.—The theory and useful effects of turbine water wheels, and best form of the parts for high efficiency. Other water wheels and wind wheels. Application of thermodyamics in the study of best engines. Relative economy of different engines. Mill Work and Machineri/.—Trains of mechanism studied with reference to their resistance and efficiency; best forms for transmission of power for short or great distances; forms of the parts for securing desired results in power and velocity; elastic and ultimate strength of parts. Machine Drawing.—Working drawings of original designs; finishing in water colors, and in line shading; details for shop use, according to the practice of leading manufactures. PROJECTS AND PRACTICE. The shop practice of the first year has already been described. The second year practice will have for its object the production of some model or machine. The students, under the immediate direction of the teachers, carefully determine the dimensions and shapes best suited for the parts of some machine, produce them in neat and accurate working drawings, and make tracings for' shop use.
