American-La France Test at Bethlehem

American-La France Test at Bethlehem

In describing the official test of the American-La France motor pumping engines recently delivered to Bethlehem, Pa., the Bethlehem “Times,” in the issue of September 23, said: The official test of the new motor fire engine recently delivered to the borough by the American-La France Fire Engine Company, of Elmira, N. Y., was made yesterday afternoon for a period of one and one-half hours, in charge of P. E. Zimmerman, deliverv engineer for the Elmira Company. The test proved very satisfactory to Chairman H. A. Becker, of the Fire Committee, and Fire Chief C. E. Bender, who witnessed the demonstration which took place at the Monocacy Creek, at the Pure Oil Company plant. The motor engine is of the type No. 10 and the contract requires a discharge of 500 gallons per minute at a 120-pound pump pressure from draught. The capacity was exceeded by nearly 100 gallons in yesterday’s test. C. D. Stewart, sales agent for the company at its New York office, also witnessed the test and he, too, was gratified with the result. Delivery Engineer Zimmerman, who had charge of the demonstration, has gauges which accurately measure the capacity of the discharge. Another test will be made at the same place on Saturday at 1.30 p. m. The first test with a 50-foot hose line, 1 1/2-inch nozzle, 78 pounds nozzle pressure, and 122 pound pump pressure, showed a discharge of 589 gallons per minute during the 130 minute period of the test. In the second test a 150-foot line of hose was used with a 1 1/2-inch nozzle, 80 pounds nozzle pressure and 230 pounds pump pressure. The discharge per minute amounted to 275 gallons for a 15-minute test. In the third test two lines of 150 feet of hose, one siamesed into 250 feet of line, were used, with three 7/8-inch nozzles, a pump pressure of 110 pounds and nozzle pressures of 80, 50 and 50 pounds. The total discharge was 520 gallons during the 15 minutes pumping. In the fourth test 150 feet of hose was used with an inch nozzle attached and a nozzle pressure of 130 pounds and a pump pressure of 180 pounds. The discharge of water amounted to 337 gallons per minute. The test lasted 15 minutes. The last test was made from a 60-pound fire hydrant with a line of 150 feet of hose, 1 1/2-inch nozzle, 80-pound nozzle pressure and 130-pound pump pressure. The water discharged amounted to 596 gallons per minute. The test lasted 15 minutes. During the test of the apparatus the engine was shut down for five minutes in order to change a broken spark plug. In an interview with a “Times” reporter, Mr. Zimmerman expressed himself as greatly pleased with the results of the various tests. In a speed test between Bethlehem and Allentown the engine developed a speed of 55 miles per hour.
