THE SEAORAVE WATER TOWER.
A new water tower has just been perfected by the Scagrave company, of Columbus, Ohio. It embraces many new and useful features that will he certain to appeal to any chief engineer who takes an interest in the latest improvements in fire apparatus. The base of the new tower is attached to the turntable with steel forgings. The springs balancing the weight of the tower tire inclosed in steel tubes and are governed by a screw attach d to the frame by an adjustable ball and roller hearing journal-box hung on a vertical axis. It works in a bronze nut hung on both horizontal and vertical axis, which avoids all possibility of binding. This device permits the raising of the tower in a few seconds by one man. The elevating tower is tel scopic. being made in two sections, the upper section being raised by cable and crank. It is made in any length from 50 to 75 ft. On top of the upper section is a flexible pipe, with discharge-nozzle controled by on : man on the ground directing the stream in any direction at will. This tower is provided with the Scagrave automatic controling valve — a recent invention owned only by the Seagrav company, which makes it impossible to turn the tower over by the reaction of the stream of water. The valve acts automatically the instant the tower starts to turn over and immediately cuts off the stream. ‘1 his tower is also provided with a deck turret-nozzle rising about 5 ft. above the deck of the frame, and is arranged to throw a stream at any angle desired, convenient for use in lower floors. One of these towers was delivered to the New York fire department a week ago, and a test of it made, when it proved very satisfactory on many of the points claimed for it. especially in the time of elevating and its rigidity when the pressure was thrown altogether on one side.
