    • F02M1/00Carburettors with means for facilitating engine's starting or its idling below operational temperatures


` I. H. MASUN.
Patented Fb.19,1918.
` Application led June 30, 1917.
To all 'uf/1,0111, t may concern.:
llc it known that l, Jo'HN H. MASON, a citizen olf the l`iiite l States, residing at Heavcner, in the county of Le Flore and State of Oklahoma, have invented certain new and useful Improvements in FuelVuporizing Devices for internal-Combustion Engines, of which the following is a specification, reference being had to the agroinpanying drawings.
This invention relates to a device for vaorizing kerosene and other relatively hear y uels for use in internal combustion engines, and has for .its primary object to provide means whereby the engine may be started on highly volatile 'fuel such as gasolene7 and ,then utilizing the. heat of the exhaust gases I for the vaporization of the kerosene or other relatively heavy fuel. v
It is-another and nio-re particularob3ect of the invention to provide a carbureter -havngsei'iarate gasolem and kerosene chainbers, theexhaust manifold of the engine being provided Witlfi a heating chamber, a conduit connected to said. heating chamber with the gasolene and kerosene chambers of the carbureter, and a manually operable valve whereby communication between either of thc latter chambers and said conduit may be closed.
It is also another object of the invention to provide an apparatus for the above purpose, which is relatively simple in its construction, highly efficient and reliable in operation, and ma be manufactured and applied to the ordinary motor vehicle at relatively small cost,
With the above and other objects` in view,
., my invention consists in the novel features of construction, combination, and arrangement of parts to be hereinafter more fully described, claimed, and illustrated in "the accompanying drawings, in which,
Figure 1 is a side elevation illustrating the preferred embodiment of my invention as applied to a motor vehicle' engine;
ig. 2 is an enlarged sectional view taken on the line2-'2 of Fig. 1;
Fig. 3 is an enlarged vertical section through the carbureter; and
Fig. ll-is a section taken on the line 4 4 of eferring in detail to the drawing, 5
designates the exhaust manifold of the engine which is provided with the usual connections shown at 6 to the exhaust ports of Specification of Letters Patent.

the several engine cylinders. Belovl/ this manifold there is provided, preferably as an integral part of the manifold, a casing 7 which receives the fresh charge of gas, said casing being provided with the openings or ports 8 in one wall, through which the gas passes to the intake ports of the engine cyliinlcrs. Upon one siilc of tlnl exhaust manifold 5, a longitudinally extending wall 9 is disposed in spaced relation to the manifold andpreferably integrally formed or cast With the manifold wall. Thus, al heating chamber is formed, of which the manifold wall constitutes one of the side walls. The wall 9 may constitute a continuation of the Wall of the casing 7, the heatingchamber being separated from the gas intake chamber by a longitudinally extending web or partition indicated at 10.
The carbureter is provided with a gaso lene receiving chamber 11 and a chamber 12 to receive kerosene or other relatively heavy hydroca-rbonfuel. Supply pipes 13 and 14 respectively, extending from separate tanksv or reservoirs, are connected to these chambers, and the supply of lthe fuels is controlled by the usual valvesl operated by floats 16 disposed in the respective fuel .chambers The fuel is drawn by suction in the usual manner through the passages 17 and 18 respectively, into the nipple or extension 19 from the casing of the carburetor, said assages being separated by a central divislon Wall 20. VIn the nipple 19, a valve plate 21 is slidably mounted in suitable groovesor channels, said plate bein movvfable through an opening 22 in the ivision gas passages 17 and 18,- and valves 25 are arranged 1n these passages and operable by any approved means to control the inlet of atmospheric air for mixture with the gas. The usual needle valves` indicated at 26, are also rovidcd for controlling the passage of the uel from the fuel chambers into the passages 17 and 18. A throttle valve, indicated at 27 is arranged in the nipple 19 beyond the division wall 20, so that the vollume of the gaseous mixture entering the heating chamber 9 may be varied as desired.
A pipe or conduit 28 is suitably connected at one of its ends to the end of the nipple l19 and has its other end connected to a port or opening 29 in one end of the wall of the heating chamber. attached, to an outlet opening),r :it the other end of this chamber and is eentrallI ron'- neeted tothe wall 7 of the ,intake eaeing.
Having iibove deserilied the severul struetural features of my invention, its operation will' be understood as follows. When the engine is started, the :slidininr valve .21 is moved to close the paesaggi). 18 eomnninieat ing with the kerosene chalnber of the enrhie reter so that a mixture of gas and air will be drawn through the. passage 17 and the conduit 28 into the heating ehnmlier, from which it. passes through pipe 30 to the sev* eral intake ports of the, engine, evlinders. After the wall of the exhaust manifold has become highlyT heated b y the hot exhaust` gases, the valve plate fl is moved to `the position Shown 'in Fig. 2 to close ernnm-iuiieation between the pipe Q8 and the. gneolene Chamber 11 so that, n mixturer of kerosene and air will now be drawn from the eluimber 12 through this pipe into the heating; chamber 9. In the pessstge of the. mixture through this chamber` the Sante is. liigjlili,V heated und vztporized by Contact' with the vl'all of the exhaust manifold so that. when it is finally delivered through the pipe 30 connected to the opposite end of the heating ehamber, into the intake easing 7. the. mixture iS in a properly val'ioi'ii/.ed condition for ready `eonfrhustion. Thus, when the kerosene vapor iseompressed wit-hin the several o vlinders it will, when exploded by the Spark, exert the same driving force upon the engine Vpistons as in the use of pfasoleno vapor. lt' will thus he apparent that, by means of my invention, considerable economy may he effected by the use of low grade, fuels in the operation of the .fngine. In the. aeroinpanying dum/ingsf l have illntrated :t eonetrnef ttion and arrangement of the, heatingand intake chambers which particularly adapted for use in connection with the Ford type of automobile, but'. it is to be. understood that such arrangement is enpzrble of some modification as may be required in order that the invention may be adapted to other construe-- tions of motor vehicle engines. The several parts of the apparatus are, however, of sim-V ple form, efficient and reliable in their op- A pipe 30 is similarly,v
eration, and can be manufactured at cornparativellyY smell cost. rThe construction of earlinreter herein illnetrat'ed is not absolutely essential to the, proper operation of the apparatus, but various; other forms of the Several valves and operating menne therefor may be snbetitnted. It is, therefore, to be mailer-stood that While I have herein shown and deseribed one praetienl enibotfliment of the device, the Same. is never theless snseeptible of considerable modiiieation, and l, therefore. reservo the privilege of adopting all Such legitimate eliangesim may be. fairly embodied within the spirit. and scope of the invention as claimed.
Hoving thus fully deserilied my invention, what. l. desire to claim and Secure bv Letters Patent'. is: u
l. The :on'ihinetion with an internal combustion engine having an exhaust; manifold and :i eliainber extending' longitndinallv along one side of said inztnifold. of an intaktn'aanifoltjl lielow the exhaust, nmnifold, the woll of the exhaust; manifold constitutingr the top wall of the intake manifold. a ,egim enppiy pipe Connected to one end of the eliarnher on the exhaust. niai'iifold, and an outlet pipe connected to the other end of said chamber :1nd to the intake manifold centrally thereof.
