Application filed August 19, 1912. Serial N 0. 715,697.
to which it appertains to make and use the same.
The objects of the invention are'to provide a portable attachment which will enable a fireman to enter a house filled with thick suffocating gases and 'smokeand to breathe freely for some time therein, andthereby enable him to perform his duties of saving life and valuables without danger to himself from suffocation.
The device is also eflicient'and useful for rotection to engineers, chemists, and work ing men who are obliged to breathe noxious fumesor dust derived from the materials in which they are obliged to work.
The invention has for its further objects to provide a device which can be quickly and easily attached and carried upon the person without the delay caused by buckling straps or the use of fastening devices of any kind and thus will be serviceable for immediate use in emergencies, since a little delay will often endanger life beyond recovery.
The invention comprises a hood to be placed over the head of the user, from which depends a tube provided with an inlet opening for air and the tube is long enough to enter a layer of air underneath the dense smoke within the hall or apartment entered by the fireman, and which can be placed beyond the reach of gaseous fumes or dust, and through which pure or much purer air can be furnished to the user. The hood is also provided with an appliance enabling the operator to hear clearly what is going on about him.
The invention further consists in the combination and arrangement of parts and manner of construction of the various details hereinafter described, shown in the accompanying drawings and specifically pointed out in the claims' In the accompanying drawings Figure 1 is a side elevation of the preferred form of the device arranged in position upon the head and body of a fireman; Fig. 2 is a front elevation of the same and Fig. 3 a rear elevation thereof; Fig. 4 is an'eleva-tion of a. modified form of hood; Fig. 4 is a section of inlet'tube; Fig. 5 is a front elevation of the 'hood enlarged'; Fig. 6 is a vertical section of the hood enlarged; Fig. 7 is a vertical section of the outlet valve and exhaust pipe, and Fig. 8 is a vertical section of the hearing-1 tube.
In-ft ese views A. is a hood formed of flexible material impervious to water and gas such-as rubber cloth, and it can also be made of fire resisting material such as as- "bestos cloth if desired.
The hood is provided with a downwardly and rearwardly extending flap B which can be inserted-underneath' the coat to prevent gases or dust from entering the hood. At
the front of the hood and communicating with the space in frontof the face are the tubes D. D. which pass downwardly around the waist, on both sides of the body, so as to rest' upon the hips-and there unite behind the body to form a single tube D This tubeD 'depends behind the wearer so as to be outof the way of his hands and feet, and not'impede his movements, and at the lower extremity it is'provi'ded with the opening D which will fall with the tube to a lower level than the body, and hence will enter a zone or layer of comparatively pure air, since when the; upper part of the room is filled with fumes or gas tothe' point of asphyxiation'the lower-portion of the room will be comparatively free from smoke for some time, enabling. a quick exploration of the room to be accomplished, and quick rescues performed.
In other situations where the noxious gases are heavier than air the mouth D of the tube can be elevated above the level of the gas. This tube may be of any length desired but for ordinary use the length shown just avoiding the floor will be suflicient.
' The device as shown, is easily and quickly attached to the body by lacing the head and shoulders through the lbop formed by the tubes D, and is supported upon the hips by means of this encircling loop, and in the use to which a fireman would put it the extremity of the tube will trail naturally behind the wearer, thus leaving the arms and feet unimpeded inthen-action, fg-ee for use. The appliance can be adjusted to the head ndt y. n a e conds An additional advantage is obtained by the use of the loop which encircles the'body', since the inlet passage is duplicated at the breathe freely through theotherpontion.
