Whennear the ends of the rods the vertical cutters are raised upout of the way and the side head cutters finish to the endof the panel. To finish the panels on the two sides of the rod and millboth sides of the D-ll rods, the table is fed six times, and aheavy feed is used for the panels; while with the U-3-C. CONNECTING ROD FOR CLAM U-3-C ENGINES. rods the same work is done and the table is fed only fourtimes, although a lighter feed is used for panelling. Side rodsare also milled on this machine and with less setting, as theyare straight in both the body and the panel. The machine isbelt-driven and it is aimed to keep it running at its fullcapacity just as large a proportion of the time as it is pos-sible. EXPANDING CHUCK FOR TRUCK WHEEL TIRES. The. expanding chuck for 40-in. tires, shown in Fig. 1, is inuse at the Angus shops of the Canadian Pacific tires which they use for their 40-in. wheels have retainingrings on both sides, and, it is, of course, necessary that thegrooves for these rings be accurate in their relation to eachother and to the outside of the wheel. The tires are firstplaced on the table of a 51-in. boring mill and are set to runtrue from the outside, and they are then bored and aregrooved on the top side. They are t
