The water drains off through the pipe shown to the sewer. The water and the oil in the second tank become furtherseparated, the oil rises to a height of 34^ in. when it passes A HANDY STAYBOLT CHUCK A chuck for turning staybolts when applying in the firebox sheets which does away with the necessity of squaringthe ends is shown below.

Similarly, the water this timepassing up through a 1-in. pipe to a level of 34}/^ in., or% in. below the level of the oil, passes off to the sewerthrough the 2-in. uater pipe. The same process is carriedthrough in the third tank. Inasmuch as but little water isobtained from the oil in the second and third tanks, a smallamount of water through a /4-in. water supply is admittedto these tanks at a point 15 in. below the top of the reser-voir to assist in operating the system. By the time the oilreaches the fourth tank it is in first-class condition. Fromthere it is pumped to an elevated storage tank for distribu-tion. The pump is automatically operated by a white pineblock soaked in parafiine which is 12 in. in diameter and10 in. high. This block rises with the oil until it strikesa washer forged on the rod on which the block slides. Thebuoyancy of the block is sufficient to work levers starting
