ROTATING DRUMS IN BASEMENT USED FOR DRYINC WET FIRE HOSE
Installation in Wilmington, Del., Fire Hose Designed by Director of Public Safety of City — Invention Patented
A NEW method for drying fire hose has been developed by George L. Coppage. Director of Public Safety, Wilmington, Del., and Assistant Works Manager of the Pusey & Jones shipyard, located in that city. Patents have been granted.
A hose dryer of this type was placed in service in Eire Station No. 1, Wilmington. It consists of two drums, eight feet in diameter by eleven feet long, placed in the basement. These drums can care for five hundred feet of wet hose or one thousand feet of dry hose on each reel.
The control for the drums is on the apparatus floor. There is a trap door or slot on this floor through which hose can he fed to the basement. The drums are turned by a 1.5 h.p. motor with four speed controls. The speed of rotation can be controled by a fireman.
Air is drawn from the outside of the building, is heated to the desired temperature, and is then forced to the drums through ducts. There are three ducts on the outside and one on the inside of the drum. A unit controls the humidity, and a thermostat regulates the heating of the air.
The air conditioned room housing the drums in the basement, is also used to dry tarpaulins, cloths, etc., on racks.
Air that is drawn in from the outside of the building is passed over a steam coil which is heated by an oil burning steam boiler that heats the main building.
Chief Wiliam J. Lutz presents a comparison of hose drying by this method and the use of towers.
With towers, it requires eleven minutes to move five hundred feet of 2 1/2inch cotton rubber lined hose from the apparatus and place it in the tower; fourteen minutes to place this amount of hose from the tower back on the apparatus. This makes a total of twentyfive minutes.
With the drum dryer, five hundred feet of hose was taken from the apparatus and placed on the drum in six minutes and ten seconds. This same hose was taken from the dryer and
placed on the apparatus in four minutes and fifty-eight seconds. This makes a total of eleven minutes and eight seconds, and shows a saving of thirteen minutes and fifty-two seconds over the older method.
Chief Lutz also stated that with the hose suspended in towers, there is an added strain placed on the couplings.
