CASE FOR GAS MASKS AND GANISTERS.
Application filed June 18, 1927. Serial No. 199,800.
This invention relates to a case for gas mask canisters and has special reference to a case wherein a canister and the gas mask employed therewith may be securely held until useis to bemade thereof, while at the same time permitting ready and easy withdrawal of both the canister and gas mask from the case.-
Gas purifying materials commonly employed in gas mask canisters, for example,
activated'carbon, hopcalite, soda-lime, etc, are inclined to deteriorate when in contact with the air, owing to the presence of impurities such as moisture, G0,, etc. This deterioration, when occurring during the period of disuse, reduces the life of the canister, and when prolonged renders the purifying materials valueless for service when the emergency arises. During war time, the practice was to seal the top of the canister with a cork and the bottom of the canister with a cardboard disc similar to the ordinary milk bottle disc. This disc was removed before the canister could be used and was replaced when the canister awaited use in order to protectcanister con tents against deterioration during the period of idleness. Almost invariably, when the emergency arises for use of a gas mask, there is considerable excitement and confusion, as well as need for prompt action, so that often when the gas mask was placed in service removal of the disc was forgotten with the consequent result that the wearer could not breathe. This added to the confusion and resulted in further delay before the emergency was properly attended to, thus often occasioning serious consequences.
- Among the objects of this invention is the provision of a case for holding a gas mask canister securely and readily for immediate withdrawal when the need arises, while at the same time providing an effective means for preventing deterioration of the gas purifying materials within the canister, which normally takes place on prolonged exposure to the air or atmosphere.
A further object of this invention is to overcome the disadvantages of prior gas mask equipment heretofore described by so constructing the carrying case that when the canister or gas mask and canister are placed within the case, the canister is automatically sealed and ready for instant use upon re- A still further object ofthis invention is to provide the carrying case with means for automatically sealing the canister, when idling or in disuse, while at the same time having the canister ready for instant use upon removal from the carrying case, and this without requiring the. removal of a sealing means such as heretofore employed.
My new construction is specially valuable n protecting gas masks and canisters employmg hopcalite, because this material is readily affected by the moisture of the air.
Other, further and more specific objects of this invention will become readily apparent to persons skilled in the art from a consideration of the following description when taken in conjunction with the accompanying drawmg wherein Fig. 1 is a perspective view showing my improved case having a canister positioned therein, the front door being opened in order to show the interior of the case.
Fig. 2 is a fragmental View, partly in section, showing the lower part of the canister in position upon the'bottom of the case. i Figs. 3 and 4 are fragmental views, partly in section, showing the lower parts of modified forms of canister from that shown in Fig. 2 and illustrating their positioning upon the bottom of my improved case.
Fig. 5 is a view similar to Fig. 2, and illustrating the employment of specific resilient means upon the bottom of my improved case for effecting proper seating and closure of the opening in the bottom of the canister when properly positioned in the case.
Fig. 6 is a fraginental View, partly in sec-- tion, illustrating the use of resilient means for effecting closure of the bottom and top of the canister when positioned within my improved case.
Fig. 7 is a fragmental view, partly in section, showing resilient members gripping the sides of the canister and resilient means for effecting closure of the top of the canister when positioned within my improved case.
The apparatus comprises a case (1), preferably of rectangular box structure, and having afront door (2) hinged to the side thereof and a handle (3) to facilitate the transportation of the device from place to place,
to the rear wall are the resilient fasteners (4), which are adapted to grip the neck (5) of the canister (6) and thereby hold the canister. The neck of the canister may be withdrawn from the fasteners (4:) by the application of sutficient forward force to pull the neck out of these fasteners. The bottom (7) of the case (6) is provided with one or more projections or inward indentations (8) of suflicient area to cover all of the openings (9) of the canister, when in proper position thereon. In this position the projection (8) registers with the openings (9) of the canister and forms a seal against the admission of air through the openings (9) to the interior of the canister. In order to provide further insura-nce of tight closure, a gasket (10) of rubher or other suitable material is provided. This eifect may also be produced by having the indented portion (8) of stout rubber or by substituting for the indentation (8) asolid piece of rubber, such as used for rubber stoppers.
It will loe'seen from Fig. 2 that the openings (9) are covered by a disc (11) serving as a valve This valve cannot be relied upon to always function properly so as to insure against deterioration of the canister contents.
In positioning the canister within my improved case the neck (8) is forced into the gripping fastener i) and the rest of the canister is swung into position so that the depression containing the openings (9) will register with the projection (8) of the bottom of the case.
Fig. 3 shows the relative position of the projection (8) upon the bottom of my improved case when a canister (6) containing a plurality of sets of perforations or open ings (9") is positioned thereon In Fig. 4;, a canister similar to that shown in Fig. 3 is employed and a special gasket (12) is also used to further insure tight closure.
In the modified form shown in Fig. 5, instead of having a projection uponthe bottom (7) of the case, a plate (13) is positioned upon springs (1d) which are attached to the bottom (7 This arrangement facilitates the positioning of the canister in the case.
In Fig. 6, I have shown a modified f0 m which provides for a stopper (15) connected to the sides (16) of the case by means of a spring (17). This spring (17) forces the stopper against the outlet of the neck (5) of the canister and thus insures proper closure of same. In this arrangement the circulation of air in the canister is entirely prevented.
In Fig. 7, the canister is held by the springs (18) bearing against the sides of the canister and rests either upon the bottom (7 of the case or preferably uponplate or disc ('19), which may be of a-fiexible material such as rubber. A spring (20) projecting inwardly, from the rear .wallof the canister serves to hold the stopper (15) in properposition to insure an effective closure.
It will be seen that by the arrangements shown in Figures 6 and 7, the canister may be readily inserted into the case and will be properly held against displacement, while at the same time insuring positive sealing against the passage or flow of air at "both open ends of the canister If desired, the case (1 may bemade of suflicient size to holda gas mask as well as the canister. In such case, the gas mask may be kept attached to the canister'whenidling so that the entire gas mask equipment will be readyfor instant use when the need arises.
The present invention is notlimited-tothe specific details set forth in the foregoing-examples which should be construed as illustrative and not by Way oflimitation, and in view of the numerous modifications which nay be effected therein without departing from the spirit and scope ofthis invention, it is desired that only such limitations be imposed as are indicated in theappendedclaims.
I claim as my invention:
1. A case for a gas mask canistericontaining a material which deteriorates when air passes through it and provided with openings at its top and bottom'for the passageof air through it, said case being provided with means for sealing said bottom opening of the canistenand being provided with -means for holding the canister with its bottom opening positioned upon said sealing means.
2.
