9 Claims. (Cl. 128-206) This invention relates to oxygen breathing apparatus and more particularly to portable oxygen dispensers in combination with nose pieces.

Oxygen containers and breathing apparatus of this'general character are well known in the art; however, the known breathing apparatus are complicated and not adapted to be readily transported in the pocket of the user and they are not adapted to be readily stored for convenient access and for use. It is known that persons suffering from head colds, hangovers, heart disease, and other similar discomforts may be treated and find temporary relief by the inhalation of relatively pure oxygen. Supplies of oxygen are not usually available when required by persons suffering from these discomforts and diseases and the known devices for dispensing oxygen are unwieldy and expensive. Therefore, it is not convenient for the said persons to have access to sources of oxygen.

It is, accordingly, an object of this invention to provide a dispenser for oxygen which is simple in construction, economical to manufacture, and simple and efiicient to transport and to use.

Another object of this invention is to provide an in1- proved dispenser for oxygen in combination with a nose piece.

A further object of the invention is to provide an improved valve for use in a dispenser for oxygen.

A further object of this invention is to provide a valve in combination with an oxygen dispenser and nose piece wherein the elements of the said device coact to provide a simple and economical dispensing apparatus.

With the above and other objects in view, the present invention consists of the combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings and more particularly pointed out in the appended claims, it being understood that changes may be made in the form, size, proportions, and minor details of construction without departing from the spirit or sacrificing any of the advantages of the invention;

In the drawings:

Fig. l is a top view of a dispensing device according to the invention;

Fig. 2 is a cross sectional View taken on line 2-2 of Fig. 1;

Fig. 3 is a side view of another embodiment of the dispenser;

Fig. 4 is a vertical cross sectional view of another embodiment of the dispenser;

Fig. 5 is an end view of the dispenser shown in Fig. 4; and

Fig. 6 is a side view of another embodiment of the dispenser.

Now with more specific reference to the drawings, the oxygen dispenser 1 is made up of a container 2 which contains an oxygen bottle 3 and a valve head 4 which has a nose piece 5 attached thereto. The container 2 is preferably made in the form of a hollow cylinder having a closed bottom 7 and cylindrical sides with a hollow portion 9 therein. The upper end thereof is threaded at atent 0 ice 2,860,634 Patented Nov. 18, 1958 10 to receive the threaded head 4. The portion 9 re ceives the bottle 3 which has a sealed top 12 which maintains the oxygen inside the bottle 3 at considerable pressure. While the bottle 3 is put into the container 2, the seal on the top thereof will be intact and the bottle 3 will be completely sealed. When the bottle 3 is put into the container 2 as shown and the threaded head 4 tightened, a prick 14 will penetrate the seal 12 and form an opening therein whereby the oxygen can escape into a bore 15 around the end of the bottle 3.. The prick 14 is pressed into the head 4 and has a downwardly extending point 17 which is adapted to penetrate the seal 12 of the bottle 3 in the manner aforesaid.

The head 4 has a lateral bore 20 and a threaded counterbore 21 which receives a plug 23. The plug 23 is bored at 24 to slidably receive a handle rod 25 which extends outwardly therefrom and has a rubber valve washer 26 attached thereto. The rubber washer member 26 is held in a cup shaped flanged member 27 which is attached to the rod 25. A spring 28 urge the handle 25 outward and urges the washer 26 into sealing engagement with a seat 29 which extends outwardly from the portion of the plug 23 around the bore 24 and seals the oxygen in the lateral bore 20. A space 31 between the nose piece 5 and the head 4 communicates with nostril tubes 33 which extend up through bifurcated nostril engaging members 34.

The lower end 40 of the head 4 has the bore 15 therein and a groove 42 inside the bore 15. The groove 42 receives an O-shaped packing washer 43 which is adapted to engage the neck 44 of the oxygen bottle 3 to form a seal therewith to prevent oxygen from passing from the broken seal down into the area 9 around the bottle 3.

When the device is to be put into use, a sealed bottle of oxygen will have the neck 44 of the bottle inserted into the bore 15 in sealing engagement with the washer 43. The head 4 is then screwed into the threaded end 10 of the container 2. During this process, the seal on the bottle 3 will be intact and oxygen will be contained therein under a considerably high pressure. As the operator continues to rotate the container 2 relative to the head 4, the head 4 will continue to threadably travel inward, bringing the bottom 70 of the bottle 3 into engagement with the bottom 71 of the container 2 and bringing the prick 14 into engagement with the seal 12 to break the seal 12. This will, at the same time, bring the O- shaped packing washer 43 down slidable over the neck 44 of the bottle 3 and form a seal therearound. When the seal formed by the top 12 is broken, the oxygen will pass up through a passage 45 into the lateral bore 20 around the spring 28 and urge the rubber washer member 26 into tight engagement with the seat 29. Therefore, the oxygen will be prevented from escaping. When the operator is ready to use the device, he will insert the nostril engaging members 34 up into his nostrils and press the handle 25 inwardly. This will remove the washer 26 from the seat 29 and allow oxygen to flow up through the passage 30 into the space 31 and to move up into the nostril tubes 33 to be inhaled by the user.

Figs. 3, 4, and 5 show another embodiment of the invention which has another type of valve and operating means. The corresponding parts of the invention shown in Fig. 4 have similar numbers to the corresponding parts in Fig. 2 plus 100. The case 101 has a threaded upper end 102 which is adapted to engage threads on the outer periphery of head 104. The neck 144 of bottle 103 is threaded at to engage threaded bore 161 of the head 104. An inner peripheral groove 143 is provided in the bore 161 for receiving an O-shaped washer 142 which lies against the tapered edge 162 of the bottle 103 to form a seal therebetween when the bottle 103 is screwed up into the threaded bore 161.

A reduced size bore 164 receives the upper end of a prick 114. The prick 114 has a point 117 and the point 117 is adapted to pierce the seal 112 at the upper end of the bottle 103 when the neck 1414 of the bottle 103 is screwed into the bore 161. A flattened side 165 is formed on one edge of the prick 114 to provide an opening past the prick 114 from the space 115 in the bore 164 above the bottle 103, from thence through the bore 145 into the lateral bore 120, thence, when the. rod 125 is depressed, through the clearance space 124 therearound, up through the lateral bore 170 in the plug 123, thence around the peripheral groove 171 to the bore 130 in the head 104, and thence to the space 131 below the nose piece 134 from whence oxygen passes up. through nostril bores 133 similar to the bores 33 shown in Fig. 2.

The actuating rod 125 has a cup shaped member 1&7 having an outwardly directed flange 173 extending concentric to the rod 125. The plug 123 has an outwardly extending end 174. The flange 173 engages outwardly extruded ends 175 of a washer 176. In its unstressed condition, the washer 176 is perfectly flat and disk shaped; however, when the plug 123 is tightened into the threaded portion 121, the washer 176 is compressed and the ends 175 are extruded outwardly toward the flange 173 and there adapted to engage the ends of the flange 173. A compression spring 128 urges the flange 173 toward the extruded portions 175 when the pressure is applied to the rod 125 by a handle 178. The handle 178 is pivoted to the head 104 at 179 and swings thereabout and the ends thereof are formed as the inturned flanges of a piece of sheet metal which engage grooves 178a in the head piece 104. When the handle 173 is depressed, flanges 180 move further into the grooves 178a.

To fill the container with a new bottle, the operator will unscrew the head 104 from the case 101 and will unscrew the empty bottle 103 from the head 11M and insert a new bottle 1113 which he will tighten up until the tapered edge 162 forms a seal with the O-shaped washer 142. The point 117 of the prick 114 will pierce the seal 112 on the end thereof. This will allow oxygen which may be contained in the bottle 103 to flow upwardly through the bore 145 and engage the flange 173 of thecup shaped member 137 which will force it into sealing engagement with the extruded end 175 of the washer 176. As pressure increases in the lateral bore 126, the flange 173 will be pushed tighter into the extruded end 175. Therefore, no oxygen can leak out of the valve. When the operator wishes to sniff some oxygen, he will insert the nostril portion134 into his nostrils and depress the .handle 178. This will move the flange 173-cff of1 the outwardly extruded portion 175 and allow oxygen, tegflowthrough the clearance space 124 and up the bore 170 through the peripheral groove 171 through the bore 130 into'the space 131 and thence up into the nostril. piece 134.

In the. embodiment of the invention shown in Fig. 6, a bottle. 203 is similar to the bottle 103 and has upper threaded ends 261 which engage a valve head 234 having a nose piece 231 thereon which the operator can insert into his nostril. A valve similar to the valve inthe embodiment of the invention shown in Fig. 4 will be provided in the head 234 so that the operator candischarge oxygen from the bottle 2193 through the head 234 into his nostril through the nose piece 23%, thereby providing a treatment for relieving headaches, colds, hangovers, etc.

It has been discovered that a small bottle such as that shown can be used to contain enough oxygen to give very decided relief to sufferers from head colds, hang- The foregoing specification sets forth the invention in its preferred practical forms but the structure shown is capable of modification within a range of equivalents without departing from the invention which is to be understood is broadly novel as is commensurate with the appended claims.
