Dies B Bt then advance on A Alt forming toe M andbeing forced to move by the advance of die C on the ramof the forging machine. Die C forms toe N on the cross-tieshearing off any excess stock by means of projection 5 pass-ing into the slot in Bv These cross-tie ends are formed atone stroke of the machine at the rate of approximately 20per hr. depending upon the facilities for heating. Method of Making Boiler Crow Feet The dies for rapidly making boiler crow feet, also a fin-ished crow foot, are shown in Fig. 10. A and B are double. Fig. 10—Dies for Forming Boiler Crow Feet dies which can be used to make two sizes by simply reversingthem in the forging machine. In operation the 2l/\-xn. by 1-in. stock is heated and fedthe proper distance into slot S between dies A and B. Die Bmoves against A gripping the stock and the advance of dieC then compresses the excess material to form the crow foot,shown at D. Crow feet are cut off and shaped in one strokeof the machine at the rate of 25 or 30 an hour. The crowfoot, illustrated, is 6 in. long by 4 in. high, being made of2*4-in. by 1-in. stock. Roch Lanctot, a prominent French-Canadian member of the Canadian Parliament, in a recent speech at St. Edouard de Napierville, Quebec, declared that the Government of Canada would be wise to rid itself as soon as possible of the publicly owned railways. What is the use of adding to an investment that produces nothing but deficits? asked Mr. Lanctct. I would The brake shaft end E (Fig. 3) is made unde
