National Meter Company.
The accompanying illustration represents the exhibit of the National Meter Company at the World’s Fair, which is conceded by all who saw it to be the most extensive and comprehensive display of water meters ever made. Their location was in section Q, block I of Manufactures building, where they occupied a space 20×10 feet, fronting on two aisles. The arrangements and decorations of the display were neat and attractive and included a large picture of the company’s factory and of President John C. Kelley. The exhibit comprised a complete line of all sizes of the various patterns of meters made by the company, from a three-eighth inch Crown to a ten-inch (Jem, and the methods employed for demonstrating their efficiency were most satisfactory.
In the centre of the space, as shown in the view, was an elaborate brass meter display tank, to which were secured a line of meters. These were fitted with glass tops, so as to clearly show the working of every part of the various meters. The pressure due to the elevation of the water in the top tank of the stand was about two pounds per square inch, but there were one each of the Crown and Nash pattern working on a head of less than two inches, and accurately registering streams smaller than would waste from an ordinary house faucet which needed packing. This feature attracted no little attention from both water-works men and the general public, who have never before seen the inside of a water meter, nor had any idea of the means by which the water they use is measured.
Another demonstration, made possible by the minner in which the meters were fitted up, and which will do much to remove the opinion held by so many consumers, viz., that “ a water meter runs just the same whether the water is running or not,” was the instantaneous stopping and starting of the pistons, which were in full view, in response to the opening and closing of the supply cocks. This seemed to convince many a man who has heretofore doubted the reliability of water meters.
Perhaps the most interesting feature of the exhibit was the line of Crown meters of all sizes, from three-eighth inch up to six-inch, which were all connected and run by a three-eighth inch stream of water entering at the smallest and discharging from the six-inch. They all registered with perfect accuracy, and in fact with the discharge opening reduced to less than one-eighth inch, they still ran just as well. This is something never before attempted in a public display, and proves the principle of the Crown meter to be such that it will register equally well on small or large streams and under greatly varying pressures.
A new style of the Gem meter was shown, which is particularly adapted to use on fire or street stand-pipes, elevators and similar services, as it has its inlet at the bottom and outlet on the top, directly above, making a straightway vertical meter, with the dial on the side. This does away with the necessity of using any elbows or tees in setting the meter.
The company also had a fine display of the Nash gas engines, for power and pumping, in Machinery hall, section 15, column F, 30.
The exhibits were in charge of F S. King of the New York office. Mr. King was assisted by F. J. Bradley of Chicago, the company’s Western sales agent, and also by II. H. I.aing.
