CARBURETER.

SPECIFICATION forming pm of Letters Patent No. 663,549, dated neembepll, 1906i Application filed August 16 1898. Serial No. 688,703. (No modell) y y y To @ZZ whom t 'may concern,.-

Be it known that I, CLMENT MATHIEU, a

citizen of Belgium, ad ministrateurdlgu de, la Societe Anonyme du Gaz Aro-Ptrolique,

vwill enable others skilled in the art to which it appertains to make and use the same.

Myinveution consists, in the first place, in the carbureting of air for feeding gas-engines by sucking air through filtering layers of cotton moistened with a mineral oil, so asto reduce the latter to a fine spray or vapor, the condensation of which is prevented by a heating-tube of great surface heated by the burned gases of the engine and not submitted to any pressure, thereby producing a rich arid dry gas in which the proportion of oxygen is too small for rendering the gas explosible without further addition of air.

In the second place, my invention consists in the recarbureting of the burned products by combining the discharge-tube of the gasv engine with an expansion-chamber, where `'the burned products can fully expand, so as to conserve only the pressure and heat required for getting through tho recarbureter and for maintaining there a convenient temperature. Thegas obtained is light; -but as it does not contain any oxygen it is absolutely inexplosible in itself. It constitutes a very good heating and illuminating gas which is used for feeding the bu rner of thegas-engine, but which may also be produced in sufficient quantities-for illuminating purposes.

I attain these objects by the apparatus illusi trated in the accompanying 4two sheets of;

drawings, in which- Figure l, Sheet I, is avertical' section, and Fig. 2 a plan view. Fig. 3Sheet II, is aseotion through the regulating-valve.

The -air-carbureter consists of a cylindrical envelop A, fixed with its .enlarged portion upon the bottom of awater-tank B and closed on top. The inner space of the envelop is divided by a series of wirework grates for supporting ilteriugcotton vlayers. C, which are saturated with petroleum or other minitself is connected with ai". oil-reservoir placed at a higher level. At each aspiration of the into the carbureting apparatus at its lower part through pipe E. and by passing lupward. vaporizes the oil and carries itthrough the heating-tube. F,which is fixed .to the gassucking valve of the engine and which is surf rounded by the dischargeftube G, having a suitably-increased diameter.

The water-tank of the carburetor is connected by pipes H H with the water-jacket of the gas-engine, so as to produce a circulation of the water through said tank, which acts as a refrigerator. y 'Y The recarbureter 4A' is of similar-construction, but connected withl the expansion-cham ber I, in which enter the burned products of the gas-engine.

the ratio of consumption of the recarbureted gases are variable, the apparatusis completed by a regulator which consists in the combination of the recarbureter with a bell K or asometer, which by means of a bar L actu- Jates the key M of a double valve N, Fig-3,

Sheet II, in such a manner that as soon as the gas has raised the bell to a certain height the key M, which is hollow and partly filled with mercury, will shut olf the passage O, leading the burned products to the expansion-cham- P for the escape of said products into theatmosphere. A retaining-valie .Q is providedbetween the recarbureter and the expansionchamber I.

The burned products after having passed through therecarbureter are directed into a pressure-regulator R, and thence passk into the distribution-pipe S. A tube T is also the burner of the gas-engine.

Having fully described my invention, what I desire to claim and secure by Letters Patent isfeeding gasengines, with a second carbu reter,

connected with Vthe discharge-pipe of a gasveral oil by means of a perforated coil D, which gas-engine a certain quantity of air entere As the quantity of the burned products andV provided for leading therecarbureted gas to' having an expansion-chamber adapted to be` ber I, and open at the same time the passage IOG l. The combination of an air-carburetor for l engine, for the purpose of producing a heating andV illuminating gas by. recarbureting the burned products.

2. The combination of an air-carbureter for feeding gas-engines Wih a second carbureter 'having an expansion-chamber provided with a. gasometer bell and a. 'regulating Valve, which latter is adapted to be operated by said bell and communicates with the dischargepipe of the gas-engine, the expansion-chamberend the atmosphere as and for Iche purpose described.

3. The special construction of the recm'bureter, consisting of an envelop A', of grates `ble regulating-valve N and a bar L zit'ljaolied to bhe bell K and actuating the key M of Asaid.' regulating-Valve N, substantially as described:
