12 Claims. (Cl. 12-' -2b.s'

This invention relates toya portable oxygen dispenser and in particular to one which may be carried in the easily installed'in aworking position andeasily disconnected therefrom, aeconomical of manufacture, relatively simple, and of general superiority and serviceability.

The invention also comprises novel details of construction and novel combinations and arrangements of parts, which will more fully appear in thecourse of the following description. However, the drawing merely shows and the following description merely describes, one embodiment of the present invention, which is given by way of illustration or example only.

In the drawing, like reference characters designate similar parts in the several views.

Fig. 1 is an elevational view of the assembled dispenser, portions being broken away and parts shown in longitudinal section to reveal the interior structure.

Fig. 2. is an enlarged fragmentary longitudinal sectional view of a valve assembly used in the present dispenser.

Figs. 3, 4, and 6 are cross-sectional views taken on the'respective lines 3-3, 44 and 5-5 of Fig. 2.

Fig. -6 is a cross-sectional view taken on the line 66 of Fig. 1. 1

Fig. 7 is an end elevational view of the device taken from the mouthpiece orinhaling end.

Fig. 8 is a broken perspective view of a mouthpiece and capsule cartridge used in the dispenser.

Fig. 9 is a perspective view of a medicament capsule for use in my device.

In the form of my invention that is shown in the drawing, a container 11 for compressed oxygen, usually called a bottle or cylinder, is provided with a metering valve assembly V and a mouthpiece assembly M, including a medicinal capsule retainer R, as more fully described below.

The container 11 is of conventionally hollow cylindrical cross-section, having one of its ends 12 closed in the form of a hemisphere, its other end being reduced in diameter to form a'neck 13. The inside 14 of the neck is shown as internally threaded to engage the valve assemblyV and the outsidesurface 15 of the neck is preferably smooth and forms a hearing or contact surface for an overlying indicator dial 16. The latter is held, preferably frictionally, on said outside surface 15. The indicator dial 16 is provided with suitable indicia 17 2 (Fig. 7) denoting the degree of valve opening in terms of different rates of dischargeof the oxygen (preferably in the accepted units of liters per minute). An overlying pointer or index 18 is attached to the mouthpieceassembly M, the same being provided so that the ,user may set the rate of discharge, as desired.

In order to accurately meter'the desired amount of oxygen to be discharged from container 11, and for safety in avoiding dangerous, rates of discharge due to a too-wide opening of the valve mechanism V, said mechanism is provided witha ball check and with a micro-adjustment means of a needle valve. The valve V is arranged to provide for minute axial movement of its" needle 20 with the bodily turning of the mouthpiece assembly M, the needle being arranged to move longitudi-. nally in a bore 21 in a valve housing 22. A needle valve seat 23 is provided in the housing or body 22 and t he same is disposed in operative relation to'the needle 20 which, thereby, controls the opening 24 between the valve bore 21 and the ball check bore 25'. The needle 20'is provided with a longitudinal hole 26, terminating in a laterally directed opening 27 adjacent but rearward of the needle valve point 28 and of the valve seat 23. Thus, said opening 27 opens into bore 21. The needle 20 is moved axially by a metering screw 29, the outside threads 30 of which are adapted to engage with the threaded wall of the bore 21 in the valve housing or body 22; The

metering screw 29 is provided at its end nearer the needle 20 with a threaded hole 32 which is engaged with the exterior threads 33of the needle 20. 'The'needle 20 is l held non-rotationally by means of across pin 34 which is inserted through a transverse hole35 in the needle 20.

Said pin engages thewalls of transverse holes 36 disposed on opposite sides of the bore 21," said holes being preferably made somewhat larger than the pin 34 in order. to provide for'subsequent limited adjustment, as will. be later described. It will be "seen that the needle 20 is moved axially through very small distances for each full rotation of the metering screw 29 because the threads 30 and 32 on the inside and outside of said metering screw each have a different number ofjthreads peninch,

both threads being of the same-hand. Thus, rotationjof the metering screw 29 in one direction will move said v screw in one longitudinal direction relative to the valve housing 22, while at the same time it will move "the needle 20 in the opposite axial direction. If both threads 30 and 32 were ofthe same number of threads per inch, j

there would be no actual movement'of the needle with.

respect to the valve body. However, by making the number of threads per inch on the outside greater than. on the inside of the metering screw, a differential linear movement is obtained. In practice, the outside thread 30 of the metering screw may be provided with fifty-one] threads per inch, while the inside thread 32 of the meter-'1 ing screw may be made with fifty threads per inch.

Therefore, one revolution of the metering screw will ad vance said screw axially 5 (.0196) inch in one direction" and will draw the needle axially (.0200) inch. The net axial movement of the needle relative to the housing 22 and the needle valve seat 23 is the diiference of .0004

inch in a direction that is opposite to the axial movement of the metering screw 29. handed, turning the metering screw counter-clockwise (when viewed fromthe mouthpiece) will open the valve,

and when both threads are right-handed, turning the mou'thpiececlockwise will open the valve.

The outer end of the metering screw 29 is provided with a radial slot 37 which is engaged with a corresponding" key-like projection 38 extending from the inside 'endo f the capsule cartridge R. The valve housing 22 is pro vided on its outside surface with a taper-threaded portion 40 which is adapted to engage the inside threads 14 If both threads are left-j of the neck portion 13 of the oxygen cylinder 11. The valve housing is also provided at its end opposite to the threads with a threaded portion 41 arranged to engage the inside thread 42 of the mouthpiece assembly M. The mouthpiece assembly M is of generally cylindrical shape, the same having a cylindrical counterbore 44 at its inner end into which the neck portion 13 of the cylinder 11 extends. The index pointer 18 is provided on said mouthpiece end so as to indicate the opening of the micro-valve above described by pointing to the indicia 17 on the indicator dial 16 which has previously been described. The opposite end of the mouthpiece assembly M is preferably tapered to a smaller diameter neck 45 which is adapted to be held between the lips of the user and constitutes the mouthpiece of the present device.

in its, outer shape to non-rotationally'fit the cavity 47 and the same is provided with a terminal portion which constitutes the terminal end 46 of the mouthpiece. The cartridge retainer R is cut away laterally so that a capsule C (Fig. 9) may be inserted in the longitudinal hole or seat 48. The capsule C is provided with openings 57 at its opposite ends so that the oxygen gas flowing toward the mouthpiece may pass through the capsule. The capsule is adapted to contain suitable medicinal or perfuming materials which are volatilized or dispersed and carried out of the mouthpiece with the oxygen gas. The capsule cartridge R is frictionally engaged in the cavity of the neck 45 of the mouthpiece assembly and the key-like projection 38 on the inside end of the cartridge R engages the radial slot 37 in the end of the metering screw 29. By this means the valve mechanism V is opened and closed upon the turning of the mouthpiece assembly M.

A check ball 50 is provided in the ball check bore 25, the ball being biased against a seat 51 provided with a bleeder notch 52 of a selected cross-sectional opening so that only a safe rate of flow of oxygen can be discharged through the notch-opening 52 past the ball. The ball is' pressed against the seat 51 by a spring 53 which is held by a retainer plug 54 engaged in the threads 55 of the ball check bore 25. The use of a ball check valve with a small leakage notch is preferred over a simple restricted orifice because it facilitates refilling of the oxygen container. V

The metering screw 29 is provided with a pair of diagonally opposite grooves 56, the bottoms of which form a key for registration in a bifurcated member of a filling machine (not shown) used in connection with recharging oxygen container 11 with compressed oxygen.

When assembling the metering screw 29 into the valve housing 22, the needle 20 is first threaded into the metering screw a distance necessary to bring the cross-pin hole 35 substantially in alignment with a hole 36 in the side wall of the valve body 22. The holes 36 of the valve housing 22 are somewhat larger than the cross-pin 34 and a trial setting of the needle in the metering screw 29 need not be too accurate. The metering screw, with the needle thus inserted, is threaded into the valve body until the needle seats. The metering screw 29 is then backed away slightly, just surficient to bring the cross-pin hole 35 in the needle in radial registration with the opposed holes 36 in the valve body. The cross-pin 34 is then pressed through the needle so that its protruding ends are in registration with the cross-pin holes 36 in the valve body. The mouthpiece assembly M is then threaded onto the valve housing 22 and the capsule cartridge R with its capsule C is inserted in the mouthpiece assembly. The mouthpiece assembly is backed away slightly to permit radial. registration of the key 38 at the end of the cartridge R and the slot. 37 in the end of the metering screw 29. The cartridge R is then pressed into the hexagonal hole 47 of the mouthpiece assembly M, frictional engagement being provided so that accidental withdrawal is not probable. With the valve adjusted to closed position, the indicator dial 16 is turned so that the zero mark thereon registers with the pointer 18. The valve is then opened to the desired indicated rate of discharge of oxygen, which can never exceed that passing through the notch 52 in the check valve seat 51. The holes 58 in the body of the mouthpiece assembly M permit inspiration of air, if desired. 7

The cartridge may contain a volatile or dispersible medicament or perfume material which is adapted to be administered by inhalation with the oxygen gas stream through the mouthpiece.

It will be especially noted that the present device embodies a valve assembly that is operatively attached or connected to the mouthpiece and that said combination of elements or components provides for a novel, facile and eflicient device for the purpose intended.

While the. foregoing has illustrated and described what I now contemplate to be the best mode of carrying out my invention, the construction is, of course, subject to modification without departing from the spirit and scope of my invention. Therefore, I do not desire to restrict the invention to the particular form of construction illustrated and described, but to cover all modifications that may fall within the scope of the appended claims.
