SPECIFICATION forming part of Letters Patent No. 573,691, dated December 22, 1896.
. Serial No. 578,977. (No model.)
To (tZZ whont it Duty concern.-
Be it known that we, ALFRED ORR and ANDREW XV. CHAPMAN, of Charleston, in the county of Mississippi and State of Missouri, have invented a new and useful Safety-Hood, of which the following is a full, clear,and exact description.
Our invention relates to an improvement in safety-hoods particularly adapted for the use of physicians or for the attendants upon patients having contagious diseases.
The object of the invention is to provide an inclosure for the head of the physician or attendant in the sick-room which will prevent any germs of disease from finding lodgment in the hair, whiskers, or any other portion of the face of the attendant or physician, and likewise to prevent any germs from being inhaled, the hood being provided with tubes or their equivalents, whereby free and copious respiration may be attainable, theinhalations being obtained from the atmosphere outside of and having no communication with the atmosphere in the chamber in which the operator may be located, the exhalations being delivered outside of the room or apartment in which the physician or attendant or other wearer of the hood may be stationed.
Another object of the invention is to construct a hood of the foregoing description which will be exceedingly simple, durable, and economic in its construction, and expeditiously and conveniently attached to the person, as well as comfortably worn, and which will not interfere with the sight of the wearer or with the sense of hearing, and which will be no impediment to speech.
The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.
Figure 1 is a front elevation of the improved hood fitted to the head of a person. Fig. 2' is a vertical section through the hood and through the respiratory section of the hood, the wearers face being shown in side elevation; and Fig. 3 is a longitudinal section through the tubing.
In carrying out the invention the hood A is preferably constructed of thin rubber, and is of such shape that it will cover the entire head and the neck of the person without clinging thereto so closely as to render the wearing of the hood uncomfortable; but the lower portion of the hood is-adapted to fit closely around the neck, and each and every portion of the hood is so formed that there will be no perceptible seams, or seams that will be calculated to afford lodgment for disease-germs.
The hood is provided with an opening in the front covered by a transparent pane 10, preferably of mica or a similar material, and this transparent pane is so located that it will be opposite the eyes of the wearer of the hood, enabling the said wearer to readily observe objects.
At that portion of the hood which is opposite the mouth of the wearer the outer end of a mouthpiece 11 is secured in any suitable or approved manner, and preferably, as shown in Fig. 3, this mouthpiece at its outer end or where it passes through the material of the hood is reduced and exteriorly threaded to receive a lock-nut a. The mouthpiece 11 is made of hard rubber or of any equivalent material, and is provided between its inner end or that end which is adapted to enter the mouth and the end which is attached to the hood with a series of apertures 12, as is likewise shown in Fig. 3, and the apertures are so grouped and the mouthpiece is of such length that when the mouthpiece is placed between the lips of the wearer the lips will not cover the openings or apertures 12 therein, the air entering the hood through the apertures being breathed through the nose.
The outer or casing tube 13 is secured in any suitable or approved manner in the outer end portion of the mouthpiece 11, and the said tube 13 is preferably made of thick rubber and will be of such length that one end thereof may be carried out of a window or out of a door-opening of the apartment or room in which the wearer of the hood maybe at service.
That portion of the outer casing or covering tube 13 which is to be located outside of the apartment is provided with apertures or openings 15, so that the outside atmosphere or the atmosphere ata point distant from the room in which the wearer is operating will enter the said tube 13, and in entering the said tube will pass out through the openings 12 in the mouthpiece and into the space between the hood and the face of the wearer, enabling the wearer of the hood to readily breathe such atmosphere.
A tube 14 is contained within the outer tube 13, and the inner tube 14 is made from a very light material, preferably thin rubber, and is of considerably less diameter than the diame ter of the outer tube 13, as shown in the drawings. The upper end of the inner tube 14 is secured to the interior portion of the upper end of the mouthpiece 11 by means of a tubular plug 16 or its equivalent, and the inner tube is preferably of corresponding length to the outer tube 13, or it may be longer or somewhat shorter, as in practice may be found most desirable, but the inner tube 14 is of such length that it may be carried outside of the room in which the wearer of the hood is stationed.
In the operation of the device the hood is placed over the head so as to inclose the face and the back of the head and likewise the neck. The outer end of both the inner and the outer tubes is then carried out through a convenient opening into the external atmosphere, or the free ends of the tubes are led to a point distant from the place where the wearer of the hood may be operating or serving. The act of inhalation will be accomplished through the outer tube 13, while the act of exhalation will be performed through the inner collapsible tube ll, and it is evident that during the act of inhalation the tube 11, adapted for exhalation, will close upon itself, providing a maximum of space within the inhalation-tube 13 for conducting a large volume of air to the wearer of the hood.
From the foregoing description it will be observed that there is an entire absence of valves, or any roughened surfaces or projections liable to receive or retain germs of disease, orliable to receive and retain any matter that may be consequent upon the act of respiration. The inner tube 14, through which the exhalation is conducted, may be readily turned inside out and cleaned whenever it is desirable, and before cleaning may be removed from the exterior or casing tube 13 by simply disengaging the plug 16.
The hood covers the entire face and head. It is simple in construction and easily adjusted. It has no seams, nor are there any valves connected therewith, as heretofore stated, in which disease-germs may lodge or The device or apparatus being preferably.
made of rubber is substantially impervious to air or gases, and will aiford absolute and perfect protection to the wearer when said wearer is liable to come in contact with infected air or pernicious gases. Furthermore,
it is obvious that the tube in no manner interferes with the hands-of the operator, leaving them free for any service;
Having thus described our invention, we claim as new and desire to secure by Letters Patent 1. The combination with a hood adapted to cover the face and head of the wearer, of a respiratory device connected with the said hood and consisting of an inhaling-tube provided with openings for the admission of the air to the interior of the hood, and a second tube of thin and collapsible material secured within the first tube and connected with a mouthpiece, the said inner tube being adapted as a conductor for expired air, as and for the purpose specified.
2. In a hood adapted to cover the head of a person in a substantially air-tight manner, an outer inhaling-tube having an apertured mouthpiece extending within the hood, the said mouthpiece being provided between its inner end and the wall of the hood with openings for the admission of the air to the interior of the hood, and a thin collapsible tube contained within the first tube and connected with the interior of the mouthpiece at its inner end, and adapted as a conductor for the expired air, as and for the purpose specified.
3. In a hood arranged to substantially inclose the head of a person in a substantially air-tight manner, a mouthpiece connected with the said hood, being provided with apertures therein, a flexible tube connected with the said'mouthpiece, adapted as a conductor for inhalation purposes, and a tube adapted as a conductor of exhalations, the said exhalation-tube being of a thin collapsible material, connected with the said mouthpiece and extending through the inhalation-tube, as and for the purpose set forth.
