ALEXANDER M. HUDSON, OF

NEW YORK, N. Y,, ASSIGNOR To MELVIN A. RICE, or NEW YORK, N. Y.

. HEADPIECE FOR PROTECTION FROM BACTERIA, NOXIOUS GASES, ETC.

To all whom it may concern.

Be it known that I, ALEXANDER M. HUD- SON, a citizen of the United States, and a resident of New York, in the county and 5 State of New York, have invented a new and .useful Improvement in Headpieces for Protection from Bacteria, Noxious Gases,

Etc., of which the followin'gus a specification.

My improvement relates to head pieces for protection from bacteria, noxious gases, &c. It has for its object toprovide improved means for preventing the entrance into the nostrils or eyes of bacteria. noxious gases, &c., simple in construction and readily applied and removed, adjustable for dlfferent individuals and for different conditions, and efiicient in operation. It consists of the novel devices herein shown and described.

In the accompanying drawings. forming part of this specification-I have illustrated my improvement in its preferred form and in modified forms.

Referring now to the drawings, Figs. 1 to 7 illustrate my improved device in its preferred form, in which Fig. 1 illustrates a front view of my improvement in its preferred form as applied to the face; Fig. 2 is a view of the same in a partial side perspective; Fig. 3 is a perspective view of the support for the nose inhaler with its supporting straps; Fig. 4: is a vertical section on the line 4-4 of Fig. 3; Fig. 5 is a side view of the nose inhaler; Fig. 6 is a vertical central section through the .same, with the ball removed; Fig. 7 is a View ofthe end of the retainer as shown in Figs. 5 and 6.

Figs. 8 to 11 inclusive re resent a modifor the nose inhaler in which Fig. 8 is a face view of the apparatus in position on the head; Fig. 9 is a perspective view of the same with the head in partial side position; Fig. 10 is a perspective view of the support; Fig. 11 is a detail of the nose inhaler and connecting parts, showing a section through the part 59 and one of the nipples 60, the nose inhaler here shown differing from the one shown in Figs. 8 and 9 only in that it has a nipple on its stem for permitting air to escape.

Figs. 12 to 15 represent another modification of the nose inhaler and its support,

fication showing a different orm of support Application filed February 18, 1919'. Sefial No. 277,888.

in which 12 is a front view of the ap- 56 paratus, app (1 to the head, Fig. 13 a partial s1de view, Fig. 14 a side view of the support, and Fig. 15 a central vertical section of Fig. 14.

Referring now particularly to Figs. 1 to 7, 1 is the nose inhaler clearly shown in Fig. 5; 2 its support, clearly shown in Fig. 3; 3 the eye-glasses; 1 the eyeards in which the eye-glasses are mounte and which are made of rubber, or'other suitable flexible material, adapted to fit the face to exclude air from the eyes. The eye-glasses and guards are held in proper position over the eyes by means of a band 5, preferably elastic and of any suitable description. The support 2 is held in position over the mouth by means of straps 6 provided with suitable elastic bands 7 adapted to pass around the back of the neck and be secured in any suitable way, as by means of button 8 and catch 9, or eyes 10 and eyelets 11, as shown in Fig. 1.0. The straps 6 are further held in place by a band 12 secured to the straps 6 and passing'over the top of the head, as shown in Fig. 2. These straps are preferably made of suitable elastic material, and also are preferably provided with an overlapping portion 13, shown in Fig. 2, provided with eyes 14 fitting into suitable eyelets in the part 13. By these means the apparatus can be adjusted to different individuals. The mouthpiece portion 15 of the support 2 is also preferably connected with band 12 by elastics' 16 1 connected to holes 17 of the mouthpiece, and passing over button 18 on eye-guard 1, and, by means of an elastic 19, running from button 18 to the upper partof band 12, as shown in Figs. 8 and 9. By these means the eye-guards and nose inhaler and its support, are securely held in place, and at thesame time may be used for different individuals, the adjustable or elastic connections permitting of a wide range of, use of the apparatus for different indi viduals:

The nose inhaler 1 comprises a curved tube or nipple 20 made of rubber having a nipple 21 for insertion into a nostriL- 22 is a guard to fit the sides of the nostril to prevent the entrance of air elxcept through the nipple. Any suitable vent for discharging the expired air may be provided. In

projecting bulb 23 made of soft rubber provided with a small opening 24. The bulb' expiration will permit the air to pass up-{ ward. 25 is a retainer, which may be of any suitable construction, for holding the chemical composition that may be used. As shown, it forms part of the nose inhaler. I prefer to use a retainer composed of a plurality of sections. As shownin Fig. 6, 26 is one of the sections and 27 is another. Both of these are provided with screwthreads as shown, so that the outer one 27 may be screwed upon the inner one. In the form shown in Fig. 6 the chemical preparation 28 is laced directly inside of the container. If preferred, a suitable separate container may be inserted in the retainer 26, 27. The container may be made of any suitable proportions dependent upon the chemical preparation used. In the form shown in Fig. 6, 29 is an end plate of section 27 containing openings 30, 30 for the ingress of the air and gases. 31 is a filtering fabric, such as gauze, immediately behind the plate 29, and section 26 is provided with a similar filtering fabric 32 toward its inner end.' 33- is a metal plate provided with a central orifice to permit the air to pass from the retainer into the nipple. 34 is the usual gasket of any suitable material. The nipple end of the nose inhaler, as shown, is secured by an intermediate tube; 35 having a beaded end 36 securing it to the head of the retainer. 37 is a metallic piece secured to the head of the retainer and encircling tube 35 at both ends, and having in its upper part a slot 38. In this is secured a ball or dumbbell piece 39 loosely fitting in slot 38 so as to be free to turn or move in it.

I connect the nose inhaler and support so that the nose inhaler will be freely adjustable upon the support so that it may be moved freely to different positions and may be adjusted-to different sizes or conditions of the nostrils so that my device may be used with different individuals. In the referred form of my device illustrated in the drawing, I have shown a universal joint connection between the two, but any suitable connection for this purpose may be used. In Figs. 8 to 11 I have shown a somewhat modified form of such connection.

Referring to the specific form of these devices shown in Figs. 3, 4 and 5 especially,

I 40 is an elongated cylindrical socket on support 2 having an elongated opening 41 with a larger circular opening 42 at its middle portion. Ball 39 of the nose inhaler is inserted into cylindrical socket 40 through the circular opening 42, and can be moved horizontally' along slot 41 into any suitable position, the stem 43 of ball 39 being small eeaaao enough to permit this movement. Bat-11139 is small enough to turn in any directlon 1nside of the socket 40. By these means, and the universal connection between ball 39 and its stem 43 and nose inhaler 20, the nose inhaler can be moved into any suitable position upon its support 2. It is thus adapted to be used with either nostril, or to be placed at any angle and lifted to any height within its range, to adapt itself to difi'erent sized nostrils. Preferably, of course, I use two nose inhalers for the support, as shown in Fig. 1.

44. is a hollow projection from support 2, preferably made of soft flexible material such as soft rubber. It is adapted to cover the mouth to act as a stopper to prevent entrance of air through the mouth during the use of my device.

Referring now to the modification shown in Figs. 8 to 11, I provide the support 2 -with a fiat plate 49 preferably cut in two at having an elongated slot 51 provided with a larger circular opening 52 at the middle, each half of the plate being hinged at 53 so as to permit of a. vertical swinging movement, and each forming a spring 54 to hold it in position. This apparatus I have provided in place of the projection 40 of Fig. 3. I provide the nose inhaler 20 with a set of flanges/to hold the nose inhaler in slot 51 on plate 49. Preferably I provide two of these sets, the flanges of the lower set being 55, 56 and those of the upper set 57, 58, the latter, 58, in this case also acting the same as disc 22 of the form shown in Fig. 5. The

nose inhaler is placed in position on support v nected. This figure represents a section of the structure shown in Figs. 8, 9 and 10, and shows one of the nipples in section. 59 is a projecting stopper piece for the month which in this case is provided with nipples 60 having openings 61. These nipples are of such soft rubber that upon an attempt being made to draw in air through them they will fold in upon themselves or contract, and so act as a valve to prevent entrance of 'air, but

upon expiration will permit the air to pass through. As shown in Fig. 11 these nipples extend inwardly. Their inwardly projecting parts are intended to be held in the mouth of the user, which will make the expulsion of airthrough them easier and keep said parts. from co lapsing or folding up.

-;erably made somewhat thicker than the outer.

In Fig. 11- a second way of expelling an is illustrated, -.namely, by means of the nlpple 23. In connection with some kinds of work calling for the use of masks, it may be an' advantage to have two exits for the air to be expelled. These are provided in the form represented in Fig. 11 by means of the nipples on mem'ber'59, and the nlpple 23 on the stem of the inhaler.-

Referring to the modification 1llustrated in Figs. 12 to 15, 62 is a mouthpiece having a wide flange 63 which-has narrowed end portions 64, said flange being provided with a cylindrical opening 65 in which the retainer 66 is directly placed. The retainer is provided with a shutter 67 for closing over the portions in the end plate 68 of the retainer'. The mouthpiece and connecting parts are preferably made of rubber. They are supported in place on the head by means of bands 69 and 70, as shown. This inodifi cation of my device is intended for temporary use where it is desired, for any reason, to shut off all communication withrthe outside air for a few moments.

Various changes in the construction of,

my improved device may be made without departing from my inventive idea. For instance, while I have herein illustrated the support for the inhaler as including a mouth-covering part, it is evident that the lattercan be dispensed with where the needs of the user require this to be done. In such case the user must of course be "careful to inhale and exhale only through the nostrils. With such construction a single elastic band will be suflicient to hold-it in place.

What I claim as new and desire to secure by Letters Patent, is:

1.. The combination of eye-glasses, eyeguards therefor adapted to fit the face to exclude air from the eyes, a nose inhaler containing separate air-inlet and air-outlet means, a support therefor inwhich the nose inhaler is freely movable and adjustable, supporting straps overlapping one another to secure the said support to the head, and adjustable connections between the said straps and the eye-guards.
