CHIEF O’HANLON DESICNS NEW FLEXIBLE HOSE ATTACHMENT
Has Been in Use at Some New York City Fires for the Past Eighteen Months —Praised by Other Chiefs of Department
DEPUTY CHIEF JOSEPH O’HANLON of the 3rd Division, New York Fire Department has been granted on a flexible nozzle so designed that it can expand from a minimum length of eighteen inches to a maximum measurement of nine feet. It can be flexed from zero to thirty, sixty or ninety degrees, and at any of these angles it can be locked against back pressure.
It is the result of diligent and experimental labors of three years, and although it has been in use for the past eighteen months at numerous fires in the hotel, theatrical and shopping districts of midtown Manhattan, it has up to this writing never been publicly described.
Fire fighters in New York have been unstinting in their praise of Chief O’Hanlon’s accomplishment in having produced a device that has demonstrated to the satisfaction of the most discriminating students of fire engineering that it is one of the most progressive and useful additions to the practical side of fire fighting as yet produced.
The nozzle itself is but a strip of sturdy tubing, supported by a rigid backbone or semi-housing in the trough of which the flexible nozzle is set at the desired angle.
One of the extra-special features of the O’Hanlon device is its adaptability to the outlet of a controlling nozzle where by removing the tip of such a nozzle, the appliance can be attached by means of an increaser leading into the flexible pipe; and then opening up the control of the water.
On one of three extension pipes which can be attached, there is an indicator or pointer to tell the operator of the line or nozzle the exact direction in which the stream is playing. The tip of the O’Hanlon nozzle is 1¾ inches. The nozzle at its minimum length of eighteen inches weighs ten pounds; at three feet it weighs twenty pounds and at nine feet thirty-two pounds.
The O’Hanlon device is especially adaptable for cock-loft, wall, and ceiling fires. The inventor has demonstrated its usefulness in stairway, sky-light, partition and shaft fires, as well as for flames under docks, in hatch-ways, port holes ventilators, stairways, coal chutes and hoistways.
Chief O’Hanlon has invented an auxiliary appliance to facilitate the use of the nozzle for fighting fire through the window of the floor above from a position at the window on the next tlor below without encountering the smoke, heat and flame of the floor actually afire. This is done with the aid of a hook attachment, fashioned much after the type or style of scaling ladder window-sill hook, which, when affixed to the slender pipe immediately at the point where the nozzle starts to bend its head over the sill, it claws the sill or the sash, of the window after it is elevated from the sill below by the fireman straddling the window. The goose-neck is turned into the floor belching forth water. The pipe once rested on the sill, cannot back itself out from pressure because any one of three tentacles holds it fast at the window of the fire floor.
Another auxiliary attachment is a cross-bar and chain for supporting the slender pipe cither at the dock-side or through an opening in a roof or a puncture in a floor or across shaft windows. There is a chain attachment the links of which automatically jam fast in a peculiar shaped hook on the cross-bar. This cross-bar serves as a suspension brace and if the nozzle is dropped through a roof or a floor, the weight is sustained by the chain and bar while the operator has nothing more to do than to observe his indicator on the grip-handles of the pipe which tells him the direction of the stream.
All the while the O’Hanlon flexible nozzle-pipe is operating, the control of the water is at the controlling nozzle connection between the hose line and the O’Hanlon contrivance.
Chief O’Hanlon carries two of his pet inventions in his car and frequently uses them. They have been requisitioned by neighboring chief officers desirous of testing them and demonstrating for their own satisfaction the general utility of the nozzle in tight, crooked or peculiar places, especially in stairways and cellars of old-law tenements.
