The die head A may be slid aside before cutting offthe pipe or removing it from the machine, thereby prevent-ing the ruining of the bottom chasers by dragging the pipeacross them. The cutting-off slide is fitted with a lathe tool post; the bun-can thus be cut out of the pipe by turning the tool at an angleafter the pipe is cut off. The gripping chuck at the front ofthe spindle is universal; the scroll chuck at the rear is usedonly for centering the rotary pump delivers oil toboth the die-head and the cut-ting-off tool. This machineghs about *,000 lbs. and ismade by the Standard En-gineering Company of Ell--wood City. STANDARD 4-IN. PIPE THREADING ami CUTTING MACHINE. DIK OPERATING MECHANISM. while the machine is in motion by means of levers conveni-ently placed for the operator. The die operating mechanism is a straight line lever deviceand as it has no connection with the adjusting screw is notliable to become loose. The adjusting screw H passes througha fulcrum nut or block G. The latter is provided with a clampgib to make the adjustment positive. Moving the fulcrumblock G to the left by means of hand wheel J, which is keyedto adjusting screw H, contracts the chasers radially. TheP has an arc-shaped fin which rides on its rest and auto-matically centers the lever and connecting link E in a straightline at all points of adjustment. Grooves cannot be gougedtreads with this mechanism, as the chasers arewithdrawn from the pipe the moment the lever is raised.
