Myinvention relates to internal combus tion engines and moreparticularly to means for feeding fuel thereto- The object of the invention is the production of a sim 1e and inexpensive device which may rea ily beattached to the engine of any conventional type of internal combustion engine and which shall automatically operate to adjust or regulate the supply of fuel to the engine cylinders depending on the temperature of the engine.
.Briefiy stated, my invention consists in attaching to a heat-conveying member of the engine preferably the exhaust manifold, 21 thermostatically operated. valve which be adapted to be one; to the carhurctcr or otherfuel supplying part as well to the intake manifold or other part connected with the engine cylinders and which shall be adapted to open and feed an auxtry supply of fuel to the cylinders when the engine is cold and to close gradually to cut oil the auxiliary supply when the engine warms upto a predetermined temperature.
" other words, the position of the valve,
whether open, closed or partially open is dependent entirely on the temperature of the engine, the temperature acting to auto-v matically position the valve to regulate the auxiliary supply of fuel supplied to the cylinders in addition to that supplied through the carburetor in the ordinary manner.
With the above. and. other objects of the invention in view which will appear from the accompanying description, my invention consists in the novel parts and combinations thereof hereinafter more particularly described and then specified in the claim.
A. practical embodiment of the invention is illustrated in the accompanying drawing in which:
Fig. l is a section taken through thether- 'mostatic valve.
Fig. 2 is an end elevation, thereof.
Fig. 3 is a perspective view of the valve arm.
Fig. i is a more or less fragmentary side elevation of a conventional type of internal combustion engine showing the valve attached thereto. n
Referring in detail to the drawing: 1 indicates the removable cover for the engine block of an internal combustion engine. 52 the exhaust manifold, 3 the intake manifold, 4 the gasoline float chamber of a carburetor which is connected to the intake ordinary throttle valve for openin 11 therein where manifold by the pipe 5 and to a source of fuel supply by the pipe 6. Z indicates the regulating the supply of fuel. from the carburetor to theintake manifold and which is controlled by the. operator, while 8' indicates the usual vacuum tank pipe which forms no part of my present invention. '9 indicates a horn which is attached to the engine inany de sired manner, this and other parts of the engine not referred to also forming no part of my present invention.
10 indicates the body of my improved then I rovided with an y it mey be detachablly secured to a bracket 12 by a bolt 13 passing through said bracket and o enmostatic ,valvewhich ing. The other end of said bracket isbc ted .or otherwise secured to the exhaust manifold by means of a suitable bolt l3 which is usually found on all motors either for" holding the exhaust manifold. to the engine block or for other purposes.
The bracket may be secured to any other heat conveying member of the engine if so de'tired. The thermostatic valve 10 is provided with an upper walled space 14 adapted to be closed by a cover. 15 by suitable screws as shown. Said valve 10 is also provided with a screw-threaded nipple 16 having therein a vertical passageway 17, said screwthreaded nipple being adapted to be detachably secured to a pipe l8'extending downwardly through the top wall of the float chamber 4 and adiacent the base of said float chamber so that the lower end will always be within the fuel within the said chamber. I
The valve 10 is also provided with a lat' orally extending screw-threaded nipple 19 provided with a passageway 20 therein, said nipple being detachably secured thereto b a pipe 21, the other end of which exten s within the intake manifold 3. The passageways 17 and 20 connect with a bore 22 which communicates with the walled space 14. Slidably mounted in said bore 22 is a valve pin 23 provided with a lower pointed end '24 adapted to extend Within and close the upper end of the passageway 17. Said valve pin 23 is also adapted to close the inner end.
of the passageway 20. The valve in 23 is 26 said 15, the function of said adjusting screw being to limit the lllOVQlDGIlhOl tie valve pin :23 in the here It so desired, a lock nut may he provided whereby the adjusting screw :27 may he held in any desired or given position.
29 indicates the valve arm. The upper portion of said valve arm comprises hard rubber, gutta percha or other analogous material having a high co-ellieient of expansion The lower "portion of said valve arm which is indicated at ill) comprises a "strip of iron, steel or any other suitable material having a low c i-cllirient oi expansion. The two strips of material are fastened together, said valve arin hcingr held by one end in positionfwithin the walled space let by means ot the screw 31. which is screwed With n the body otthe valve. The outer end of the strip 30 is cut out to form a U-shaped portion 32 engaging the valve pin Within the slot interrnc (liate the head 26 and the body oi said valve pin.
As the valve ari'n comprises two strips of material having different co-cllicients of e105 pension it will flex when suliijected to changes of ten'iperature. When, therefore, the en gine is cold, the valve arm acts to raise the valve pin 23 in the bore 22, thereby permitting the fuel to flow from the float chamber" of the arhuretor up through the pipe 18, through the passageway 17, into the here through the -1 assa eway 20, through the pipe 2t and into the intake manifold 1 ot the engine,
whereby an auxiliary supply ofifuel "will be supplied to the cylinders in addition to that supplied from the carburetor in the usual manner. As the engine grows warmer, however, the heat therefrom radiates to the thermostatic valve and the valve pin is lowered in its here by the action of the valve arm until the passageways l7 and 20 are finally closed to prevent the admission of any further auxiliary supply of lue'l to the intake manifold;
' It will he readily understood that the details oi construction of my invention thus rlrscrilied may he varied eonsiderahly Without, departing: from the spirit of the invention as set 'ioi-tli in the appended claim.
What i (lllllll as my invention is:-
in coinhiiiiatio'n with an internal eoinhustion engine provided with an intake pipe, an exhaust pipe and a container for fuel, auxiliary fuel supply mechanism con'iprising a pipe line extending from said container to said intake pipe, means for controlling the passage of fuel through said pipe line, said near-1s including" a thermostat anti :1 inevalile controllin; valve operatively associated therewith, said thermostat being positioned to he suhjoct to the heat within said exhaust pipe, and an. adjustable stop member posi tinned t ljcuent said valve and constructed to engage the same to limit the extent to which said valve may he opened.
