MANIFOLD HEATJREGULATOR.

and the main object to provide a highly.

efficient and regulahlcdevice of said kind, and thereby economize on the gasolene or other fuel from which the fuel is produced. In the accompanying drawing, Figure l is i 3 of the manifold of an explosive engine. said. Fig. 2

is a longitudinal vertical section on the line in Figs. 3 and -1 Fig. 3 is a left hand end elevation of what is shown in Fig. 1 with the top of the device intact and a fragment of the engine added. Fig. at is a section as on the line. in Fig. 2. of the complete device and a fragment of the engine added. 1

Referring to the drawing by reference numerals, 5 designates the part of a gasolene engine to which the intake manifold through its upper ports 7, delivers fuel to the cylinders of the engine. said fuel being drawn through a lower port S'from the can bureter 9. The latter is surrounded by a jacket 10.

The fresh air is d awn into the carbureter through a passage 11 (see Fi g. 2) and is thus partly heated by the adjacent gas exhaust tube 12. 12. And from said passage 12 some of the hot exhau t gas passes down through a duct 13 into the jacket 10 so as to heat the carburetor and then escape from the jacket through an outlet 14 in same. 15 are the ports through which the. exhaust gas from the cylinders escapes into a series of valve chambers 16 (see Fig. 4). said chambers is provided with a port 17 through which the gas may pass downward like the arrows 18 in Fig.4 and reach the exhaust 12 by passing through an exhaust .n'ianifold 19 which forms a jacket about the intake manifold (3], which latter is thus heated by the-exhaust gas. Each chamber 16 is also provided with a lateral-port 20, which opensintoa horizontal. diverting tube or duct "21, whoselar'genend has a down-' Specification of Letters Patent.

ward extension 21 --2icommunicating with the final exhaust tube 12.

Journaled in bearings 25 along the base of the tube is a rock shaft having at one end a rocker arm 26 adapted to spring into either one of several notches in a notched segment 27, which is fixed on any adjacent stationary part/ On said rock shaft is fixed a series of wings or valves 28. each of which, in the present drawing, is shown as extending from the shaft into the valve chamber through the port 20 and arranged to close alternately the port 17 or the port 20 of the valve chambers 16, or the "valve may 00- cupy an inclined position in the chamber, so

that when the hot gas is-thus more or less diverted from the jacket 19 to the tube 21 it. is thereby also diverted from and 13 so as to reduce the heat .in tube 1.1 and in the carburetor and itsjacke't 10. And that this regulation of heat of said parts saves all the fuel that. is wasted when the intake manifold and carbureter are allowed to deliver either too cold or too hot gas into the explosion chambers.

This invention is especiall applicable to engincsof automobiles and auto trucks. but is also applicable to explosive engines in general.

that we claim is v In a device of the class described. an intake manifold arranged to deliver fuel into the combustion chambers of an explosive eugine. an exhaust manifold spaced as a jacket about the intake manifold and having a series of valve chambers forming passages arranged to receive the exhaust gas from the engine and a final exhaust outlet for said gas, a diverting tube extending along all the valve chambers and having one end directed into the final exhaust outlet. each valve chamber having three ports, one-port arranged to receive the hot exhai gas from the'engine, the second port to adn 1 said gasthe tubes I2 into the outlet manifold and the third port positibn, and a 'cjii-rbureter furnishing gas to admit more or less of said gas into the dito the intake manifeld,
