To all whom it may concern.'
.Be it known that I, GEORGE FEANoIsy JAUBERT, a .citizen Vof the Re ublio of Switzerland, residing atv 155 oulevard Malesherbes, Paris, France, have invented vcertain new and useful lm roved Respirators; of which the following is a specification.
This invention has for its object improvel ments in respiratory appliances enabling at-` ing n the accompanying drawingz-Figure l is a general yiew of a constructional form of the apparatus. Fig. 2 is a detailv view of the modified form of apparatus. f
The' apparatus com rises a battery ofsay.l
four reservoirs a b .c of steel or other appropriate' material -containing air, gas or other respirable gaseous mixtures under pressure. These reservoirs are mounted on a tube z upon which a gassupply valve` or cock e is arranged. The reservoirs a b c are in direct communication with this cock; the reservoir d or' emergency reservoir communicates with the tube z by the intermediary of a separatevalve or cock f provided with an .operating rod g.
The gas supply valve e is .connected by means of a pipe x with a pressure reducing valve/h controlled 'by a handle i and terminating in the discharge pipe m. The passage x is also rovid'ed'wi-th a pressure gage .j and-a brano valve fc enabling direct communication to be established with thepipe which there is mV through the -small branch as. The pipe m,' which is preferably flexible, opens into a regulating bag or pocket o of material impermeable to gas and which may be ilexible or rigid; from this pocket there proceeds the aspiratory pipe p ending in a nozzle y on lixed. a mouthpiece n preferably composed of a material such as indiai'ubber. From the nozzle y there is branched an. expiratory p pe r rprovided with a valve s o enng outward. he aspiratorypipe p 'li ewise contains a valve g opening into the place-the reservoirs are charged with air, gas
or respirable gaseous mixture under pressure'. At apressure of say 150 atmospheres about 90() liters ofjgas can be stored in a reservoir having a capacity of 1.5 liters, The apparatus is then yfitted to the body of the person who is to use it, the reservoir'being y.attached to the chest or to the back by means yof .belts passing through the loops 1, 2, 3, and 4.A Y The india-rubber part n at the end of the nozzle .is placedin the mouth. Atf'thev beginning the cocks e and f being closedthe cock e is first of all opened, then the handle of the pressure reducing valve is depressed to enable the 4gas to flow through the pipe m into the pocket o, then through the aspiratory pipe toward the pipe y, and the mouthpiece fn, which Ais only placed in the mouth after an adequate provision of gas has collected inthe Apocket o.- The supply through the' reducing valve' h may be regulated in the Vfollowing manner z--Vhen the workman has only to perform a moderate amount of work, he arranges the handle i of the reducing valvein such a manner that the valve permits, of a supply of 10vliters of air per minute; when, however, the work is hard, he arranges the handle so as to obtain a supply of 20 liters.-
The aspiration of the air takes place through the pipe p and the valve g preventing the entrance of unbreathable gases; during expiration, on the other hand, the valve q is closed and the 'valve s opens to permit of the escape of the respiration gases. The pressure gage shows the quantity of respirable gas remaining in the cylinders at any moment.
' When the cylinders al t c are empty, the cock f is opened for the consumption of the reserve of gas in the cylinder or cartridge d.' The workman should now retire from the place containing the unbreathable atmosphere, the provision of air remaining in the cylinder d giving him ample time to do so. It may happen that owing to rust forming in the steel cylinders the fine perforations of the reducing valve will become choked. The valve 7c is then openedand the respirable gases are able to flow directly into thepipem; in this oase the flow of respirable gases taking place without any reduction of the pressure, it is, advisable not to open the branch valvec completely, and to withdraw at oncesfroin the foul atmosphere. presents every guarantee of safety; the workman is warned that he must withdraw as soon as he perceives that the first three cylinders a l) c are exhausetd and the fourth cyl- The apparatus thereforeV esA inder d supplies him with all the air necessary during such withdrawal.v
The duration of respiration permitted by the four cylinders of this apparatus is from to 45 minutes, according as the supply furnished is 10 to 20 liters. The duration of the utilization of the apparatus may of course be increased or diminished by altering the vnumber of cylinders, their dimensions and the pressure of the gas.
Fig. 2- represents' a constructional form of apparatus witha single reservoir. The reducing valve h is regulated by means' Ao a screw t with stop yoke u. The branch valve c is lconnected by means of a flexiblepipe w L with the no'zzlec to which. the discharge pipe is iitted.
The operation of the apparatus is the same; the pressure gage j furnishes a check on the quantity of air contained in the cylinder c andthe branch valve 7c enables the air to reach the mouthpiece directlyif the perfora-` respirable gas under pressure, a supply pipe leading from said reservoir, lan asp'lratory pipe, a pressure reducing valve between the supply'pipe and the aspiratory pipe, akbl passaround the ressure-reducing valve, and
manually opera le control valve in the bypass, substantially as described.
