. Automotive industries . Another feature of conspicuous advantage is found inthe magneto mounting.

This construction called for one right handand one left hand magneto and also had the disadvantagethat the magneto bracket came in such a position that thebed timbers of fuselage could not be extended rearward. In Model E-2 the magnetos are set at an angle to eachother, which lifts them out of the way of the fuselagemembers. Also, instead of the single transverse shaftthe bracket carries two short shafts each provided witha bevel pinion the two meshing with a single bevel whichtakes the place of the spiral gear. This makes the rota-tion of the magnetos both alike and so simplifies the han-dling of The three oil pumps groupedin a single assembly fittinginto the crankcase, with wa-ter pump below and outsidethe crankcase Positive clutch usedin camshaft drive toenable fine angularadjustment in tim-ing valves Mentioning spare parts, it has been an object in layingout the new model to use as many as possible of the de-tails of the 180 hp. engine, which was made in large num-bers by the Wright-Martin Corp. and for which there arestill fair stocks of spares in various places. Thus themarine type connecting rods which were the first Ameri-can innovation and the first departure from Hispano prac-tice are retained unaltered. The crankshaft and cam-shafts are identical, the water pump is the same, althoughit attaches to a quite different type of oil pump, and so onthroughout the smaller parts. WHILE it is important to maintain a low-pouring tem-perature for casting aluminum alloys, it is equallyimportant to avoid overheating the metal in the furnacecharges. Doubtl
