TESTS OF FIRE APPARATUS AT COLUMBUS
During the last convention of the International Association of Fire Engineers, held at Columbus, Ohio, the following tests of fire apparatus were made:
Seagrave Company, Columbus, Ohio—Service Test of Aerial Motor Truck after a Long Run: Length of run, 2 6-10 miles. Time from start to finish, including raising 75-ft., quick-hoisting extension-ladder, 7 minutes 41 seconds. Average speed while running, 22 miles per hour. Fastest mile at rate of 28½ miles per hour. Under service conditions, the speed could evidently be improved through better adjustment of the motor. Official timers: Captain Greely S. Curtis, of New York, and Chief T. Owens, of Denver, Colo. The motor truck was followed at the start by a Seagrave motor chemical engine, which arrived at the end of the run considerably ahead of the motor truck.
Webb Motor Co.—Vincennes, Ind.—Running Test of Combination Gasoline and Hose Wagon:—The engine made a run of 2.6 miles in 3 minutes 41 seconds at an average rate of 42 miles per heur. Highest speed during run, 50 miles per hour. The engine connected to a hydrant at the testing ground and played water through 100 ft. of hose with a 1⅜-⅛. nozzle in 1 minute 15 seconds after arrival. That time included some delay in opening the hydrant as well as the time needed to locate properly and make both hose and hydrantconnections. Total time for running 2.6 miles and delivering water through hose, 4 minutes 56 seconds. Official timers—Captain Greely S. Curtis and Chief T. Owens. Pumping Test—The engine was shifted to a cistern with water nearly up to the level of the street and drew water promptly on starting the pumps. Two 100-ft. lines were siamesed into a l j-iin. Eastman nozzle. A pressure of 138 lb. was maintained at the engine and 80 lb. at the nozzle —showing a discharge of 405 gal. per minute,
American-La France Fire Engine Co.— Tests of First-Size Metropolitan Engine:— First Pumping Test—The engine was stationed at a cistern and for three minutes played through four 200-ft. lines of 2½-⅛. hose siamesed into a single 1¾-⅛. nozzle through a short length of 4-in. hose. Water-pressure at the engine between 145 and 165 lb. Best pressure at the nozzle, 111 lb. Maximum discharge, 950 gal. per minute. Average discharge, somewhat less. Second Pumping Test: Four 200-ft. lines, with four 1-in. ring-nozzles. Maximum discharge, 925 gal. per minute.
Test of Automatic Pressure-Governor:— Two lines of hose equipped with 1%-in. shutoff nozzles were attached to the engine in order to demonstrate the operation of the new pressure-governor which was exhibited in connection with this Metropolitan engine. The governor is designed to open or close the throttle of the engine automatically, so as to keep the water pressure at the pumps at any desired pressure, whether one or both of the lines are playing or are shut off. The governor worked satisfactorily at the test. It held the working pressure steady within 10 or 15 lb. when the second line was either opened or shut off, and it shut down the engine promptly whenever both lines were shut off. and, similarly, started the engine promptly whenever a nozzle was opened. By suddenly shutting off two lines simultaneously, while the engine was working at good speed, the momentutn_of the engine carried the pressure up 60 or 70 lb., which is less than often occurs when the engine is controled by hand.
Test of American-La France Automatic Aerial Truck—Seventy-five-foot ladder. Ladder was raised and tip extended in 32 seconds, with men on ground and tillerman in seat. The main ladder was raised in 5¼ seconds with men on truck and ready for test.
Exhibition ot Automobile Tiller and Steering Device.—Satisfactory driving exhibition of combination wagon, and service truck eqtiiped with novel steering device.
Nott Fire Engine Co., Minneapolis, Minn.— Exhibition of Second-Size “Universal” Fire Engine.—The Nott Fire Engine company exhibited a second-size “Universal” engine and operated it under working conditions. The special innovation shown by this engine was the use of a counterbalance, which successfully prevented all vibrating or jumping while the engine was run at high speed. No axle clamps are necessary with this new construction. The engine was connected by two 50ft. lines of 2½-⅛. hose to an Eastman Deluge set, with a 154-in. nozzle. It was given a scientific test for seventeen minutes by Captain Greely S. Curtis, consulting fire department engineer, with the following results: Average steam pressure, 117 lb.; average water pressure, 110 lb.; average draught, vacuum, 7½ in.; average pressure at nozzle, over 66 lb.; gallons discharged per minute. 740; average speed, including unintentional slowing up, 324 revolutions per minute; slip of pumps, excellent, less than 4 per cent. The test showed satisfactory results under working conditions. No attempt was made to boost the pressures, so as to produce exaggerated results.
Eastern Coupling Co., Camden.
Test of Patent Quick-Action Coupling and Spray-Nozzle:—Good spray combined with solid stream.
Woodhouse Manufacturing Co., New York. —Test of Paradox High-Pressure Nozzle Holder:—Two 100-ft. lines were siamesed into a short length of 3½ in. hose, with a 1¾-⅛. nozzle, and were worked from Nott engine. Nozzle-pressure, 70 lb. Special attention of the committee given to this device. The powerful stream was easily handled by means of this holder.
A. D. Cole Co., Camden, N. J.—Test of Cole Nozzle-Holder:
The holder was secured by iron staple driven in pavement; pressure at 1’4-in. nozzle, 133 lb. Test satisfactory.
Samuel Eastman Co., Concord, N. H.— Test of Eastman Ladder-Pipe — The Eastman ladder-pipe was attached to the top of the main ladder of one of the aerial trucks in regular service in the Columbus fire department. The pipe threw a good 1⅛-⅛. stream under 77 lb. nozzle-pressure, without exerting any side-thrust on the ladder. The direction o the stream was controled through the turn table of the truck.
Test of Eastman Deluge Sets: Excellent streams varying in size from 1¼-⅛. to 2-in. were discharged through Eastman Deluge sets in the course of testing the various steam and gasoline engines. The Deluge sets proved as convenient and satisfactory as usual.
Niagara Hose-Washer, Lockport, N. Y.— The Niagara Hose-Washer is arranged to clean hose with water supplied by a 2½-⅛. line from a hydrant. The hose to be washed is drawn through the appliance.
Westinghouse Company, Schenectadv. N. Y. —Tests of Westinghouse Gasoline Fire Engine:—First Test.—Connected to hydrant: Two 200-ft. lines siamesed into an Eastman Deluge set, with 1½-⅛. nozzle. Nozzle-pressure, 48 lb.; engine-pressure, 96 lb.—total discharge. 462 gal. per minute. Second Test.— Two 50-ft. lines, with nozz’es between 1⅝ in. and 1¼ in. in size. Pressure on larger nozzle, 44 lb.: engine-pressure, 78 lb.—total discharge. 504 gal. Third Test.—One line 450 ft.: nozzle, 1-in. smooth-bore; 55 lbs. pressure at nozzle. 133 lbs. pressure at engine—total discharge 219 gal. Fourth Test.—The engine was shifted from the hydrant to a cistern. One line, 600 ft. 1-in. smooth nozzle: nozzlepressure, 35 lb.: pressure at engine. 100 lb: discharge. 175 gal. per minute.—Fifth Test.— One 100-ft. line. 1 3/16-in. nozzle: nozzle-pressure, 55 lb. Engine-pressure. 112 lb.—discharge, 305 gal. per minute. The engine ran easily at each test. It picked up the water promptlv and evidently could run steadily and efficientlv for hours together.
Kanawha Chemical Manufacturing Comnanv, Charleston, W. Va.—Test of Chemical Engine.— 150-ft. line of chemical hose taken to the roof of the Board of Trade building. The engine uses ammonia gas. derived from powdered ammonia, dissolved in a 75-gal. chemical tank, the solution being expelled bv compressed air. Pressure in air-tank. 1,050 lb. The pressure in the chemical tank is controled by a regulator. During the test the pressure at the engine fell from 125 lb, to about 90 lb. The 3/16-in. nozzle used on roof showed over 70-lb. pressure. The solution is claimed to be noninjurious to persons or fabric. When the tank is only partially discharged at a fire, the remainder does not have to be thrown away, as is frequently the case with other chemical engines.
New York Coupling and Supply Company, New York.—Test of combination nozzle and holder: High-pressure nozzle to be used for solid streams or chemical streams with or without spray. Can be played in any direction from the ground or from a ladder. Test satisfactory.
Combination Ladder Company, Providence, R. I.—Test of Baker Wagon Pipe.—Nozzle, 2-in.; pressure at nozzle, 72 lb., fed by three 150-ft. lines from two second-size Columbus engines; pressures at engines 155 to 170 lb. Total discharge, 1,008 gal. per minute. Test from one engine, same length of hose, 1¾-⅛. nozzle; nozzle-pressure, 78 lb. Water-pressure at engine 140 lb.—total discharge, 803 gal.
Test of Baker Ground-Pipe:—Siamese pipe fed by two 150-ft. lines of hose from one Columbus second-size engine: size of nozzle, 1 11/16-in.; pressure at nozzle, 70 lb.; pressure at engine reported to be 170 lb.—total discharge, 708 gal. The pipe held its position on the ground without requiring attention.
The M. H. Hart Company, New York, N. Y. Test of the Hart Turret-Pipe.—The pipe was mounted on a hose wagon and was supplied with water through three 150-ft. lines of hose from two Columbus second-size engines; 2-in. nozzle; pressure, 74 lb., pressure on engine No. 2, 176 lb. and engine No. 6, 204 lb.—total discharge, 1,013 gal.
O’Neil Basement-Pipe.—The test of the O’Neill basement-pipe was made by playing down through an aerial ladder, while the ladder was lying horizontal. The pipe can discharge in any direction. The sample worked satisfactorily though somewhat leaky.
The Egan Coupling Company.—Test of the Egan Couplings:—The couplings made by this company were tested in same lines with which high-pressure tests of nozzles were made. They gave entire satisfaction.
C. A. Schmidt, Indianapolis, Ind.. had an exhibition of Automatic Rotating Sprinklers. A special shed filled with combustibles was built for testing this device. A fire, with well-oiled kindling, was set in the shed not far from one of the sprinklers. The sprinkler went off in twenty seconds and extinguished the fire promptly. Four sprinklers on a supply pipe outside of the test building were also tested by applying kerosene torch. Average time.—Sprinkler heads let go 10 seconds after applying torch.
Globe Manufacturing Company, Pittsfield, N. H. —Exhibition of Waterproof Spits.—-The good qualities of the Globe turn-out suit were demonstrated by an agent, who remained dry while standing in the thick of the spray from the heaviest streams.
