62 THE ARTISAN Nelson E. Nachtrieb Carl A- Witte George Mathieson Joseph J. Hackett 1941 ' Drafting lt is impossible to develop a Hnished tradesman without a delinite knowledge of the language of the trade World of which we will eventually be a part. One of MeKinley's aims to impart to us as much working material as is possible during our course here, therefore trade drafting, another term for the language of the trade World is taught to us. Vtle endeavor to become intelligent readers of the blueprint which in reality is the means employed to pass on to the tradesman the orders for the part or parts of the Work he required to do. In order to do this we must be taught the fll11fl3.1Il611lI2l.lS of mechanical draft- ing' and sueh necessary steps the uses and names of the various instruments, different types of lines, how to read a. scale, relation of views, the principles ot projection, how the objects appear to the eye, and intersections. These funda- mentals are the same for all of tl1e trades, but problems pertinent to eaeli trade are used making' it necessary to have a separate eourse for each trade. This explains the necessity for referring to the drafting taught in a. vocational school as trade drawing. As far as possible we are working under conditions which approach those we will be under in industry. NVhen We begin work in the drawing rooms, we are given a blue print to work from. l7Vhile it is true that this first work is more or less copy Work, yet each print contains new steps for us, and we pro- ceed in such a gradual Way that at the end of our two yearsf sojourn we are not only able t.o read a. blueprint but also able to make our own drawings or plans from rough shop sketches, isometric drawings, and completed projects. An idea of the work aeeomplished by us here at McKinley may be had from the following ouilines of each trade. V

THE AIi7'ISA,N 63 In our Plumbing Course we are taught through our drawing the component parts of the drainage system sub-divided as follows: Spout connections, air vents, main and branch sewers, laundry tray connections, sink and bath room connections and refrigerator Wastes. By this niethod we find ample ,opportunity to learn the various fittings such as bends, tees, tys, traps, etc., and their functions. This also gives us, we believe, an excellent opportunity to learn the laws concerning such installations as laid down in the city code. We next take up hot and cold water installations in detail.. All of the fore- going work is part ot the plans of a complete drainage and water system for a one family home. The last thing we do to make the drawings showing a complete plunibing installation from a single line diagram. We inake the coni- plete plans and elevations. In bricklaying we make drawings ot straight walls, corners, and crosses from 4 up to and including 20 walls, in the ditterent bonds, isometric being intro- duced as the course progresses. Paneling, iireplaces and arches are taken up quite extensively. In plastering we are taught to draw plaster as applied to tile and latll. Mouldings, pancling and arches are stressed very thoroughly with us. The students in carpentry draw the connnon wood joints, various types of sill construction, framing details of floor joists, partitions, outside walls, doors, windows, etc. Isometric drawings are used here to a great extent. We draw complete sets of working details of two-story houses, covering framing, and trim. In bricklaying, plastering and carpentry we all finish our courses with the drawings of floor plans and elevations of a two-story house in. brick, stucco or frame according to the trade we are following, with a good explanation of symbols used.
