osmaoan'rna:
Be it known that I, VICTOR R. Hnr'rnnu, who am a citizenof the French Republic, residing at Detroit, in the county of Wayne and State of Michigan, have invented cor-- tain new and useful Improvements in Carbureters, of which the following is a specification.
This invention relates toicarbureters, and has for its object an improved arrangement of parts whereby the en ine which it serves may be most economica ly'run under ordinary and normal'conditions, and which is at the sametime capable of furnishing a much richer explosive mixture than usual, when,
for example, the low temperature of the air makes it diflicult and often almost impossible to .secure ignitionof a mixture that under ordinary circumstances is fired without dilliculty.
In the drawings :Figure 1 is an elevation, partly in section, of a carbureter of my improved type, showing the controlling and regulating valve in its normal open position. Fig. 2 is a fragmentary and largely sectional view-showing the valve adjusted so as to connect the supply chamber of the carbureter directly with the intake pipe connecting with the"engine cylinder. Fig. 3 is a similar vie'w,'with the valve closed, so as to shut 01f the supply chamber from the outside atmosphere, thereby enabling a richer mixture to be ejected from the spraying jet in the carbureting chamber.
A represents the float chamber of a car bureter, in which is the usual stemiided float B, and from which a passage leads to the supply chamber D. A passage E in turn leads from this chamber into the carbureting chamber G, terminating in the spray nozzle F. The throttle member H regulates the quantity of explosive admitted to the engine cylinder.
At the top of the supply chamber is a three-Way valve J, which, in the open position shown in Fig. 1, connects the interior Specification of Letters Iatent.

of the chamber directly with the atmosphere, thereby subjecting its interior and its liquid fuel contents, which it has-received through the passage G, directly to the influence of atmospheric pressure, thus giving this influence to the regulation of the supply of fuel furnished to the supply chamber and -therefro1n sucked into the carbureting chamber. When, however, a richer mixture than ordinary is temporarily wanted, as for example when the temperature is so low that an explosive mixture of ordinarily suitable proportions that would at working temperature easily ignite, can with difliculty, if
at all, be ignited, a pull upon the controlling link K turns the valve plug J so as to close the top of the supply chamber entirely, thus cutting off the atmospheric pressure regulation ofthe quantity offuel delivered into the supply chamber, and drawn thence into the carburcting chamber. A much richer mixture is thus drawn through the spray nozzle by the suction in the exhaust to the engine cylinder, so rich that, in spite of the low temperature of the air its ignition bythe usual means is easy. And. by turning,
the valve J farther to the position shown in Fig. 2, the supply chamber may be connected directly with the exhaust portion ofthe car- ,bureter chamber which leads to the engine What I claim is l. In a carhureter, the combination of a float'chamher, a supply chamber connected therewith, a curbureting chamber connected with said supply chamber, a pipe leading from said supply chamber to a point in said carbureting chamber near the throttle, and a valve whereby the same may be closed and whereby the connection between said sup ply chamber and the outside air may be regdated, substantially as described.
2. The combination of a. float chamber, a .5 supply chamb 1", and a carbm-eting chamber mnnected in the order named, a; pipe leading from the top of the supply chamber to a point above the, throttle in ihe Carburetin'g i chamber, and a i 'alve whereby the same may be regulated, and by'whcaa' furbher movel0 ment the interior 0f the supply chambar may be exposed to atmospheric pressure.
In testimony whereof I aifix my signature in presenc of two Witnesses.
