Ahrens-Fox Engine Test at Lynn
The Lynn, Mass., fire department recently gave a public exhibition test of its new Ahrens-Fox motor pumping engine and it passed all the tests, and far exceeded the specifications. It was pronounced entirely satisfactory and was accepted. The test was made under the rules of the National Board of Underwriters, by Bertram E. Ames and John Caldwell of that board, John P. Ahrens, vice-president of the Ahrens-Fox Company, was also present. The test was made in a rainstorm with the ground covered with slush. Many citizens and representatives of other fire departments were present. Chief E. E. Chase was in charge of the arrangements. In the capacity test the specifications called for 120 pounds pressure and 700 gallons delivery, a pressure of 125 pounds at the pump was made and 745 gallons delivered. The pressure was increased to 105 pounds and 884 gallons were thrown. This far exceeds the requirements. The second or high pressure test showed a pressure of 200 pounds at the pump, the requirements were 250 gallons through a long line of hose. The pressure was sent up to 212 pounds and 378 gallons were thrown. This pressure was increased to 283 pounds and a discharge of 443 gallons was the result. During the trials the pumps never stopped, and when changes were being made from one test to another, the engines were constantly in operation. The engine replaces a steam fire engine in the Glenmere fire station.
