l Application led November 27, 1905. Serial No. 289,369.

- vard Malesherbes, Paris, France, have in- -vented certain new and useful Im rove` mentsrRelating to the Propulsion or Sub-` marine Boats, of which the 4following is' a specification. This invention relates to an apparatus for the propulsionof submarine or submergible vessels, and its object is to permit of adopting an internal combustion engine for operating such vessels both on the surface and when submerged', without necessitating two separate motors for these purposes, while avolding the inconveniences and complications result-ing from the employment ofelectric aceumulators. A According to this invention, the explosion gas lengine is fed in a closed cycle, fi. e.,with

out air beimT utilized for the combustion of the fuel. 'Fhe combustion gases exhaust i into a purifier or washer, Where the steam is cond-ensedand lthe `carbonio-acid partly absorbed, "so that an inert gas is obtained, which is then added with oxygen and is capable of being again utilized in the engine for producing iquid fuel.

In the accompanying drawings Figures 1 and 1EL are views in elevations of the various devices constituting the apparatus and taken together constitute a complete elevation of an explosive mixture with the of the apparatus, and taken together constitute a complete plan ofthe device.

a' is the explosive gas or combustion motory of exhausting outside the vesselwhen on the surfaceor exhausting into the puriiier or dissolver when operating in a closed `cycle When submerged.

At b2 is shown the union connecting the three-way cock to the puriiier or dissolver.

f is the purifier which instead of being a ro- ,tary apparatus of the-Standard type, as in the example given in a French Patent No. 309,633 is a plate type washer, in order to the device, and Figs. 2--2JL are views in plan' avoid having a large liquid capacityrwhichfis important owing to the'dis 'lacementvdffthe center of gravity due to t e jpitcliingfaiid tossing ,of the-vessel. `With the same object and withthe same success, the inventor vhas utilized pulverized Water or alkaliirei-iiqiiid Washers of the Koerting type.

g indicates an excess gas outletwhichf-.is only utilized-in cases vin which thel puriiicationis not complete.' In suclrca-sesfthe'exlcess of as unabsorbed. in the purifier would accumulate in the cycle, and naliythe ressure would become such that it Woul exceed the pressure of the. oxygen supply at p, so that this latter would be un'abl'eto intro*- lduce the oxygen into the-cycle which Would result in the stopping of the motor. As soon as the pressure in .the cycle, Whiciris about 10 c. m. of water, increases abnormally, the bell regulator brises andopens the=cockg, which regulates the supply to the suction chamber of the gas pump '7c shown in Fig. v1, which forces this excess into the sea, usually in the" Wake formed by the screw in such 'a manner as to com letely dissolve the' gases. The pump-,7c is sufgciently the excess as out at a dept of- 50 meters.-

i is a bre l regulator similar to theforego'- ing and romwhicli the motor sucks the ordinary air at a constant pressure, through the' pipe i2 Which terminatesat the two three- Way cocks y'. During propulsion on the-surface, that is to say inan open cycle, -these cocks lare turned in such a Way that the suc-- sup lied and the motor operating in a closedv Cy c e. v Z are the oxygen stora e tubes which may, of course, be replaced y an appropriate means for the production o this as on 1powerful to force board Z1 is the oxygen collector Z2 the ranch for introducingv oxygen to fill these tubes.

m is the oxygen reducing valve which reduces the pressure from 120'kilograms or 1 more to 1- kilogram, which is the pressure in the reservoir vtube n. It -is this reservoir (tube a that feeds the motor b the intermediaryof the bell regulator o vwiiich acts upon the cock o1. p isthe oxygen distributing valve With the regulating cocks g.

r are the fuel pumps (which may be gasoiio Iene, splrlt or the like) each of which supplies a air of cylinders.

n the accompanyinr drawing the Washing of the gases may e effected with sea Water Which is taken in at t and supplied 'to the )urifier at i!1 see Fig. 2, this Water being discharged into the tank u and finally into the sea by the pump y. In this case the .urification is only partial. In order to efect complete purification and to obtain a perfectly closed cycle, the tank u is filled with an alkaline liquid (such as caustic soda, caustic otash or the like) and the ump y causes t iis liquid to circulate throng i a pipe (which is not shown) in the Washer until exhausted, it then being forced into the sea and replaced by fresh liquid. Under these con- 'ditions the tank should be of sufficient size for a submersion of several hours.

3 indicate the inlet and outlet 4for the circulating cooling Water of the motor.

By applying this apparatus the Weight aild Volume ofthe propulsion means of a subl marine vessel are considerably reduced, and

. forth the com it 1s also possible to maintain constancy in the Weight of the boat and preserve the interior atmosphere from vitiation.

Having now particularly described and ascertained the nature of said invention and in what manner the same is to be performed, I declare' that what I claim is:

1. In an ap aratus for the purpose set forth, the comliination of an explosion gas engine, a gas pipe, a silencer placed thereon,

anexhaust Valve, a purifier, a three-way cock permitting either of exhausting outside the vessel or into the purifier, a pipe leading fronr the purifier for supplying the purified exhaust gases to the clmine, a pump for the excess gases and an oxygen supply to the engme. 2. In an ap aratus for the purpose set liination of an explosion gas engine exhausting into a purifier, an excess gas outwith a cock controlled by means of a bell regulator, a gas pump for forcing the excess gas into the sea, a pipe leading fromthe purifier for supplying the purified exhaust gases to the engine, and an oxygen supply to the engine.

3. In an ap )aratus for the purpose set forth, the combination of an explosion gas engine exhausting into a purifier, an excess gas pump, a bell regulator for theaspiration of the gases and a pipe for supplying the exhaust gases, three-Way cocks arranged on said pipe for supplying either atmospheric air or exhaust gases to the motor, oxygen storage tubes lconnected with a reducing valve and With a reservoir tube, a pipe for supplying oxygen to the motor and an oxygen distributing valve with regulating cocks.

4. In an ap aratus for the purpose set forth, the com ination of an explosion gas engine exhausting into a purifler, a seawater supply to said purifier, a discharge tank connected with the purifier, a pump for causing the water to circulate througl the purifier and for expelling the washing water into the sea, an excess gas pump, a bell regulator for the aspiration of the gases and a pipe leading to the motor, three-way cocks arranged on said pipe for supplying either atmospheric air or exhaust gases to the motor, oxygen storage tubes connected with a reducing valve and with a reservoir tube, a pipe for supplying oxygen to the l motor and an oxygen distributing valve with regulating cocks.

5. In an ap )aratus for. the purpose set forth, the com )inatiou of an explosion gas engine, an exhaust valve. connected with a purifier or washru, a plate type washer having a small liquid surface, a sea-water supply to the Washer, a discharge tank connectedwith said washer, a pump for causing the water to circulate through the. purifier and for expelling the washing water into the sea, an outlet and an inlet for the circulating coolingr water of .the motor, an excess gas pump, a bell regulator for the aspiration of the gases and a pipe for the supply of exhaust gases, three-Way cocks arranged on said pipe for supplying either atmospheric air or exhaust gases` to the motor, oxygen storage tubes connected with a reducing Valve and with a reservoir tube,a. pipe for supplying oxygen to the motor` an oxygen distributing Valve with regulating cocks and fuel pumps for supplying the motor.

In testimony whereof l have hereunto placed my hand at Paris, France this eleventh day of November, 1905.
