(GRANTED UNDER retailer or MAI-.cn 3, 1a ans AMENDED APRIL so, 1928; 370 o. G. 757) This invention described herein may be manufactured and used by or for the Gov ernment for government purposes, withoutthe payment to me of any royalty thereon.

5 This invention relates in general to respiratory apparatus and more particularly has reference to a gas mask allowing access of free flowing agents, other than air, out of contact with the surrounding medium.

Previous to this time, the gas masks employed in warfare and industry have not allowed for taking nourishment or stimulants while wearing the mask. In numerous instances, such as in gas attacks of long duration and mine accidents, it has been necessary to remove the masks' heretofore employed if it was desired to partake of food, or drink, thus giving rise to unnecessary casualties. F i

1 It is obvious also that any attachments on a mask for connection with specially constructed ccntainerswill not allow for sustaining persons in emergencies of'the charact-er described where such accessories are not usually available. Even if access to a mask is afforded however, ordinary containers cannot be utilized with any safety, as the contents are likewise exposed to contamination. V 1 "An object of this invention is to provide a gas mask allowing access of free flowing agents, otherthan air, out of contact of the surrounding medium. f

Another object of this invention is to provide a gas mask through which free flowing agents may be consumed or administered.

A further object of this invention is to v provide a gas mask allowing accessof free flowing agents out of contact with the surrounding medium, having an attachment communicating with the mask for automatically opening and sealing ordinary tins containing such agents.

. A still further object of this invention is to provide a gas mask allowing access of free flowing agents out of contact with the surrounding medium, having an attachment for procuring such agents from an ordinary container, and replacing with purified air, the portion of agents consumed in the container.

on line 12-12 of Fig. 9.

A still further object of this invention'is to provide agas mask allowing access of free flowing agents, out of contact with the surrounding medium, having an attachment for opening ordinary tins containing such agents and maintaining a seal from the surrounding medium in the" event of detachment with the mask or removal from the :tin.

With these and other objects in view which maybe incidentto my improvements, the invention consists in the parts and combina tions to be hereinafter set forth and claimed, with the understanding that the several necessary elements comprising my invention, may be varied in construction, proportions and arrangement, without departing" from the spirit and scope of the appended claims.

. In order to make my invention more clearly understood, 1' have shown in the accom panying drawings means for carrying the 79? same into practical efiect, without limiting the improvements in their useful'applications to the particular constructions, which for the purpose of explanation, have been made the subject of illustration. p

Fig. 7 is a sectional view of the valve unit shown in Fig. 6. i

Fig. 8 is a top View of the adapter. Fig. 9 is a sectional view of the adapter taken on line 99 of Fig. 8, showing the mechanism inserted in an ordinary container;

Fig. 1.0 is a side view of the adapter. Fig. 11 is a horizontal sectional view taken on line 1111 of Fig. 9.

' Fig. 12 is a horizontal sectional view taken 1 0 Referring more particularly by numerals to the drawings in which the same and similar elements are designated by like symbols of reference throughout, and more especially to Figs. 1 and 2, there is shown the novel respiratory Valve comprising an annular plate having the usual downwardly projecting rim for receiving the edges of a conventional facepiece. A plurality of deflector tubes integrally formed in V-shape, are provided on the top of the plate 1 for passing the inhaled air over the eye pieces of the mask to prevent clouding the vision.

The deflector tubes 2 and 3 communicate with a stem 4 on the under side of the plate for connection with a hose which may be attached to a suitable canister or other device for purifying air contaminated with any objectionable gases or smokes, or to supply oxygen to the wearer. The opposite end of the plate is provided with an upwardly projecting stem 5 for receiving a conventional flutter valve to afiord an exit for the exhaled air. The angle tube in the preferred form is die cast or otherwise integrally made, preferably of some suitable light metal or alloy, so that a composite structure is presented.

This invention contemplates casting en bloc with the bottom of the angle tube, a downwardly extending cylindrical projection 6 in which is formed a pair of tubes 7 and 8. The tube 7 is preferably concentric with the projection 6 and communicates with an inverted L-shaped mouthpiece 9, integrally cast on the plate 1 between the deflector tubes and opening adjacent the mouth of a person wearing the mask.

The tube 8 opens into the top of the plate 1, thus affording communication with the interior of the mask. A plurality of conventional tire valves, of the type used in the valve stems of inner tubes, 11 and 12, are mounted in the tubes 7 and 8 for a purpose to be more fully hereinafter described, and the bottom of the projection 6 provided with an annular indentation 13, for receiving the rim of a sleeve on an adapter shown in Fig. 9.

The adapter comprises a cylindrical body portion 14, having the lower end formed with a tapered extension 16. The top of the extension 16 is provided with a circumferential depression 17 for receiving a rubber stopper 18, held at the top by an integral annular shoulder 19. A plunger 20 having a central bore 21 is mounted in the cylindrical body portion 14 of the adapter, designed to slide in a tubular sheath 22. The lower portion of the plunger 20 is formed with a reduced extension 23 terminating in point 24 having formed therein a series of orifices 25, communicating with the bore 21.

The end of the tubular sheath is tapered as at 26 and provided on the inside with a rim 27 adapted to act as a seat for spiral spring 28, surrounding the reduced extension 23, and held at the other end against the body of the plunger 20. The tapered end of the sheath 22 is formed with a series of serrations 29. It will thus be seen that the plunger 20 may be pushed out of the sheath 22 against the force of the spring 28.

The outside of the plunger 20 is indented on one side, as shown at 31, and a portion of the sheath adjacent cut away as shown at 32. The side of the extension 16 is provided with an aperture 33 to allow communication with the interior of the tube 14. When the sheath 22 is forced upward against the action of the spring 28, however, the aperture 33 is closed by the wall of the sheath 22 and passage of air out off.

A. closure 34 provided with a series of apertures 35 is formed near the top of the sheath and provided with a centrally located upright pin 36. It is intended that ashort section of hose 37 be employed for connecting the angle tube to the adapter and held thereon in any suitable manner such as by a tape 38.

When the hose 37 is pushed over the projection 6, on the angle tube, the rim of the sheath 22 on the adapter will it in the annular indentation 13 on the bottom of the projection 6, and tens press down against the stem on the valve 12 and open the same, allowing air from the mesh to enter the adapter. The prong 36 concomitantly presses against the stem on the center valve 11 opening it in the same manner, allowing passage of free-flowing agents through mouthpiece 9.

hen the adapter is attached, a person wearing the mask may thus obtain fluid from the tin in which it is inserted through the adapter and angle tube, and finally out of the mouthpiece 9. It is apparent that as the fluid is removed it will be replaced by air from the interior of the mask, from the passage 8 communicating with the mask and passing into the container through the adapter.

Another form of angle tube, for use in connection with a separate valve unit, is shown in Figs. 4 and 5. The deflector tubes 2 and 3 are formed on the plate 1 in the same manner as that shown in Fig. 1 together with the flutter valve stem 5. The lower portion of the L-shaped mouthpiece, however, is made up as a part of the hose connection stem 4, by a partition 41 provided on the interior, thus affording a tube 42 protruding from the mouth of the stem, adjacent the inner side of the wall.

The vaive unit comprises a section of tubing 43 having the projection 6 integrally formed on one side. A partition 44 is formed against the side of the tube adjacent the projection 6 and communicating with the bore 7 to provide a tube 45, extending above the tubing 43, and allow communication of the bore 6 with the tube portion 43.

I It is intended that the stem 4 and the end of the tube section 43, be joined by a suitable hose 46 and the tubes 42 and connected by a rubber tubing 47. The bottomrim of the tubing 43 is oined to a canister,'or other,

air purifying device, through a hose 48 in the same manner as the hose stem 4 shown on the angle piece in Fig. 2.

The operationof this invention may readilybe understood by having reference to the adapter shown in Fig. 7 for connection with the projection shown in either Fig. 2 or Fig. 7 V

The adapter is clasped on the upper end and forcibly thrust through the top of a conventional container 49, preferably with a single blow.. The spreading walls of the point 24 and the tapered end of the'sheath 22 will enlarge the rupture until the soft rubber stopper 18 is properly seatedtherein and the contents hermetically sealed from the surrounding medium.

The hose section 37 is then fitted over the projectione6 and a seal of the openend of the adapter from the surrounding medium insured. The seating of the rimof the sheath 22 in the annular indentation 13, on the projection 6, and the pin 36, which: results in the opening of the valves 11 and 12, makes it possible to consume liquids held in the container through the mouthpiece 9.

The plunger 20 is maintained in position against the pressure of, the spring 28 by the. binding effect of the ruptured edges of the container on the rubber stopper softhat the sheath 22, when pressed against a icontainer bottom, insures the automatic closing of the valves 11. and 12, should the container be inadvertently dislodged beforev removing the adapter from the projection 6. It is manifest that when the adapter is removed from the'projection 6 that, the valves are automatically closed by release of the pressure exerted by the rim of the sheath 22 and the pin 26.

It will be atonce apparent that thisinvention is in nowise limited to the consumption of the liquid foods'but with some slight modification in the form of the adapter may be successfully utilized for administering anaesthetics in the field or other locations in which the air is contaminated with objectionable gases or smokes, as well as being used for allowing smoking while'wearing the mask-under similar conditions. It is to be understood also that the valves'shown or a secondary set in the adapter may be manually operated in a manner to insure closing should pressure be released sufficiently to permit the stopper to become loosened from the food container regardless of the pressure on the sheath or whether it touches the bottom ofthe container.

There is accompanied by this invention a gas mask allowing access of free flowing agents, other than air, out of contact with the surrounding. medium, in which liquid may be secured from an ordinary tin container uncontaminated and the contents replaced with purified air, the device being hermetically sealed from the outer atmosphere, with provision for maintaining the seal should either the container or device become disconnected from the mask.

While I have shown and described the preferred embodiment of my invention, I wish it to be understood that I do not confine myself to the precise details of construction herein set forth, by way of'illustration, as it is apparent that manychanges .c
