RESPIRATOR.

SPECIFICATION forming part of vLetters Patent No. I718,785, dated January 20, 1903.

Application iiled September 16, 1902. Serial No. 123,571. (No modela tion.

My invention relates to improvements in respirators; and one object that I have in view is to provide a simple, efficient, and portable construction by which the user is enabled to breathe fresh outside air in rooms, railway-cars, ofces, and other inclosed places without exposing the person to the danger of taking cold or to drafts of cold air incident to the opening of a window or ventilator, said device being primarily designed for use by those afflicted with diseases of the lungs, but is also available for use by persons engaged in shops or laboratories where operators are obliged to labor in impure air, gases, or the like.

A further object of the invention is to provide means by which the pure outside air may be supplied with ease to the respirator, so that the device can be used by a person while sleeping, reading, or otherwise engaged.

The device may be held in place on the users head or face by any suitable means, and said device is equipped with means to permit the ready exit of the exhaled breath either into the room or to the outside air through a suitable tube, at the option of the user.

Further objects and advantages of the invention will appear in the course of the subjoined description, and the novelty will be dened by the annexed claims.

Reference is to be had to the accompanying drawings, forming a part of this speciiication, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective View of one form ofthe respirator in position for use. Fig. 2 is a view of a window board or slat having means for communicating with the respirator. Fig. 3 is an enlarged vertical sectional view through one form of the improved respirator. Fig. et is a detail perspective view of a window-Slat, showing it in ali extended position for use in the window; and -Fig. 5 is a detail perspective view of the respirator, showing one means by which it may be held in position on the face.

5 designates the shell or casing of the respirator, which is closed at one end by a head 6 and is provided with an inclined leg 7 at its opposite end. The upper side of the tubular casing or shell is provided with the flanges 8, to which are attached the nipples 9. The nipples are preferably made of rubber or other elastic material, having longitudinal passages 10, which communicate with the chamber of the casing 5, and these nipples are adapted to be sprung over the flanges, so as to hold themselves in place by frictional engagement with said flanges. The nipples are removably itted to the casing, and they are of such shape and dimensions as to lit in the nostrils of the person using the inhaler. The nipples may be shaped to meet the requirements of individual users, and I do not, therefore, limit myself to the employment of nipples of any particular shape and size.

11 designates a tube which is united to the under side of the tubular casing 5, near the head 6 thereof, in a manner to communicate with the chamber of said casing, and within this tube 1l is secured another tube 12, the latter having an inclined upper end 13, forming a seat for a flap-valve 14. This flapvalve is preferably hinged at one edge, as at 15, to the internal tube 12, and said valve is arranged to open inward to the position shown by dotted lines in Fig. 3, thus allowing the admission of air to the casing 5. The valve is normally held to its seat by means of a light spring 16, supported in a suitable way Within the tube 11. The fresh air from the outside of a room or apartment is supplied to the respirator by aflexible or pliable tube 17, which is provided at one end with a tubular coupling 18. This coupling is fitted loosely around a projection at the lower end 9 of the inside tube 12, and said coupling is provided with an annular rib 0r collar 19, with which engages a catch or spring 20, fastened to the outside of the tube 11. The coupling 18 is free to turn on the internal tube 12, and it is prevented from disengaging from the respirator by the catch or spring 20, thus allowing the coupling and the tube to turn freely in a manner to overcome twisting of the iiexible tube.

Theinclined leg 7 at one end of the shell or casing is provided with an internal tube 21, having a beveled or inclined lower side, forming a seat 22 for an outwardly-opening checkvalve 23, the latter being preferably hinged to the tube 21, as at 21. The check-valve 23 is normally held to its seat by a light spring 25, and this check-valve is adapted to open in a manner to permit the free escape of the breath exhaled from the lungs of the user; but said valve is adapted to close inwardly in order to prevent the admission of air from the room or apartment into the respirator. It' desired, the leg 7 may discharge the exhaled breath directly into the room; but I also contemplate the employment of means whereby the noxious vapor exhaled from the lungs may be discharged to the outer atmosphere. This means contemplates a flexible tube 26, having acoupling 27, which is revolubly fitted to a projecting end of a tube 28, the latter being secured in the extremity of the inclined leg 7. The coupling 27 is provided with a collar 29, which is engaged by a catch or spring 30, attached to the leg 7, thus permitting the coupling to turn on the leg and preventing the iiexible tube 2G from twisting.

The Iiexible tubes 17 2G may be of rubber or other suitable material; but I may employ tubes which consist of a wire lining su rrounded by a sheath or jacket of oiled silk. I do not desire, however, to limit myself to the employment of any form of fiexible tubing.

The respirator may be attached to the head or held on the face of the person by any suitable means. In Fig. 1 I have shown the respiratorcombined with a mask 3l, which serves to partially inclose the nipples 9 and is adapted to fit around the lower end of the nose, thus enabling the respirator to be worn with ease and securing a tight connection between the respirator and the nose of the user. In Fig. l I employ a metallic device consisting of a band 32, adapted to be passed around the head over the ears, or I may employ a metallic bow similar to temples used on spectacles. Another means for holding the respirator in place is shown by Fig. 5, wherein a tape or cord 33 is fastened to the respirator in a suitable way, and this tape may be tied around the head of the user. It is evident, however, that any suitable means may be adopted for holding the article in place on the head when it is in use.

In Figs. 2 and 4t of the drawings I have shown a window-Slat adapted for use in connection with the improved respirator. This window-Slat consists of the sections 34 35, which are slidably connected together by an intermediate strap 36, the latter being fasf with the drawings.

tened removably to one section and arranged to embrace the other section in a manner to permit the slat to be extended or shortened for the purpose of fitting windows of dierent widths. The sections 34 35 of the extensible slat are provided with nozzles 37, to which may be connected the tubes 17 26 of the respirater; but, if' desired, a single nozzle 37 may be used on one of the members of the slat. If the respirator is equipped with the supply and escape tubes 17 and 26, respectively, the extensible Slat should be provided with the two nozzles, and this construction enables fresh air outside of the room to be supplied to the respirator and the exhaled breath to be discharged from the room into the outside air.

The operation of the device is obvious from the foregoing description, taken in connection The device enables the user to inhale the pure outside air while sleeping, reading, writing, or otherwise engaged without exposing the person to cold air. When low temperature prevails outside, the air is quickly and suiciently warmed by passing through the tube 17 to the respiratorthat is to say, a tube full of cool air one inch or more in diameter within a room full of warm air is quickly warmed as it passes to the respirator, and in extreme cases or of exceedingly low temperature the air may be sufciently warmed by simply extending the length of the tube. The sectional construction of the slat allows it to be fitted to Windows of different widths, and when the slat is not in use it may be folded compactly for storage in a trunk or other article.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. Arespiratorcomprisingachamberedcasing, a depending inlet-leg communicating with said chamber and provided with a valve, means attached to the casing and extending upwardly therefrom to fit the nostrils of a user, an outlet-valve to control the egress of air from the casing, and a supply-tube connected to the inlet-leg.
