f Be 1t known that I, RUDOLPH lxYsELA, a

citizen of the yJnited States, residing at Los Angeles. in they county of Los Angeles and State ofl California, have invented new and useful improvements j in Motor-Control Means andvSystems and Methods, of which the following is a specification` This invention relates to motor control means and system and method, and has for` an object the prevention of running an engine when the same commences to overheat, thus preventing excessive friction and wear of the various parts.

In practicing `the Invention Iirprovide-` means whichk may be associated with the` water jacket of an engineso that when the water reaches a certain temperature the `said means will operate and in so operating will stop the engine. The said means may be utilized` in [connection withfany lone of a number of systems forfeeding gasoline ork other fluid to theengine, and in particular the device is adapted to close the air vent,

in a gravity tank when the water reaches a definite temperature in the w'ater jacket surrounding the engine, or to open the air valve in the pressure system Where gasolinei or other fluid is forced to the intake mani,-

fold of an engine, thus preventing the gaso-k line from flowing tofsaid manifold when the valve is open,y ork with the well-known vacnum system.

which controls theair supply to anyone of the systems above-,mentioned and which` valve is operated by thermostatic control, this control operating when the temperature of the water in the water jacket reaches a certain degree. s i.

It will be seen that a device of this character will'overcorne many diliiculties caused by an overheated engine or motor. A motor may be overheated due to any number of causes, such yas impaired water circulation i automobiles; a slipping of the fanbelt ork motor .fang improper 4carburetor mixture In particular, the invention comprises a member provided with a valve causing excessive heat inthe engine; and any' number of difliculties. My invention effectively overcomes all this by immediately `stopping the operation of the engine when the engine begins to over-heat and a driver of an automobile may then examine the different parts to determine the cause of the overheating of the engine. y

The invention has for furthery objects the provision off an improved motor control means and system which will be superior in point of relative Isimplicity and inexpensiveness, taken in conjunction with utility, du-

rabilityy and vgeneral efficiency and service ability.

lWith the above mentioned and other objects in view, the invention consists in the novel and. useful provision, formatiom-construction, combination, association and interrelat1on of parts, members and features, as illustratedy mssome `of its embodiments .in the accompanying drawing, described in the following detailed' statement and finally pointed out in the claims. Y f ln the drawing: f

Referring with particularity tothe drawingfwherein I, have illustrated three em bodiments of the invention, oneembodiment is?y illustrated in Figures 1an'df2 andthe. two other embodiments in Figures 5 and 6.

'A designates a motor and kB vmotor control means. In Figure 1. ais a vacuum tank and b the intake manifold of thelmotor A and c, the-water acket of said meten The` fait i 1,458,304:

vacuum tank includes the usual two chambers 1 and 2 having divisioning walls with a float member 3 within the upper chamber 1, and a cap member 4 closing the upper chamber 1. The cap is provided with an opening permitting a pipe 5 to enter the same, which pipe leads from the gasoline tank (not shown). A second opening in said cap accommodates a valve plug 6 carrying a pipe member 7 leading to the intake passage of the manifold, and a. third opening 8 in said cap, which openingV ordinarily receives the air vent pipe. The opening 8 is so arranged as tofallow atmospherization of the outer chamber 2 at all times, as shown by the passage 9 and for a controlled atmospherization of the chamber 1 through the medium of a valve 10. The float 3 carries the-usual stem 11 to which is pivoted a lever arm 12. The system likewise includes a toggle lever 13 which is actuated by movement of the float 3 through the medium of a link 14 connecting the leverarm 12 with the toggle lever 1 3, which lever 13 actuates the valve members 10 and 15.

The operation of the vacuum system is as follows: A valve (not shown), is placed between the chambers 1 and 2; the suction of the pistons in the engine A on the intake stroke creates a vacuum in th and this vacuum closes the valve which is bet-weenvthe chambers 1 and 2, said valve not being shown, and also draws gasoline from theY main supply tank (not shown), into the chamber 1. As the gasoline flows into this chamber the float 3 rises. YVhen this float has reached a determined point, it operates the valves 15 and 10 so as to open the valv 10 and close the valve 15. This of course will immediately atmospherize the interior of the chamber 1 and prevents a re-drawing of further gasoline through the pipe 5 into the upper chamber 1, and likewise causing the valve leading into the lower chamber to open and through which the gasoline immediatelyT commences to flow into the lower or emptying chamber. This lower chamber 2 is always open to the atmosphere through the medium of the opening 9.

In particular the pipe 16 leads from the chamber 2 to a carburetor l associated with the engine A. The means B is associated with the air vent opening 8 and acts to prevent atmospherization of both the chambers 1 and 2,and in this particular differs from the general operation of the vacuum system. As before stated, the chamber 2 is usually under atmospheric pressure in order to allowgasoline in `the lower chamber to feed through the pipe 16v to the carburetor, in a perfectuninterrupted flow.

The means B comprises a housing 17 open at one end as at 18 and closed at the other end, as 'at 19. The interior of said housing chamber 1,

is screw-threaded from the open end for a distance, as shown at 20, and an annular plug 21 provided with screw threads is received within a portion of the housing 17. The annular plug 21 is likewise screwthreaded as at 22 so as to receive one end of a threaded nipple 23. The other end of said nipple is adapted to receive the screw threaded cap 24, which is adapted to receive the enlarged end 25 of a pipe 26, which pipe likewise carries a screw-threaded plug 27 adapt-ed to be received within the opening 6. Thus when the device is assembled the enlarged end 25 is held closely to the nipple 23 so that no air will be lost through the joint. The plug 21 is provided with a conical valve seat as at 2S and a stem member 29 having a valve head 30 is adapted to contact with said valve seat during a certain operation of the means B. lin particular the base or end 19 is recessed as at 31 to receive an end of t-he stem 29, and surrounding said stem is a compression spring 32. Said spring has one end abutting against the interior surface of the end 19, and the other end against a pin 33 passing through the stem 29 and normally urging the stem outwardly so that the valve head 39 will not engage the seat 28. Likewise surrounding and carried upon the stem 29 is a thermostat c which includes two members 34 and 34El identical in construction and cach provided with angularly directed end portions 35 and 36 having openings 37 therein adapted to receive the stem 29. The thermostat c comprises two metals 36 and 39, 33 being brass and 39 being iron, or they may be of any other metals having unequal expansion due to temperature change. The housing 17 is provided with an opening 40 and the stem 29 is relieved as at 41 so as to allow air to enter the opening 49 and through a passage 42, and thence into the vacuum tank. In the embodiment Vshown in Figures 1 and 2 the housing 17 carries a solid lug 43 provided with screw threads 44. The water jacket c is likewise bored and tapped, and the member 44 received within said tapped bore, as shown at 45. The thermostatic members 34 and 34a havev one end` bearing against the plug 21 and the other bearing against the pin 33. Obviously, if the temperature of the water' reaches a. given degree the heat willr be conducted through theV solid lug 43 to the housing 17, and the said heat will thus affect the thermostat e tending to expand or twist the ends 35 and 36 of the members 34 and 34a, and this will close the valve so that air cannot enter through the opening 8. Of course this closing is done under the resistance eX- pended by the spring member 32. If the air opening 8 were closed the vacuum system would cease to function andv as a result the motor would stop running, due to lack of fuel feedingto the carburetor el.. kThe point at which` they meansB .will operate ldef pende` rto a `certain r`extent upon the:y Com' pre'ssionof thefspring 32, asfthe spring k32 may `exert soy muchy pressure as to prevent y the valve from closing.k This compression It will 'be a *simple matter ftoicialibratevthe device B `by the adjustment justdescribed.l InvFigure 3fin placevofiusing the solid lug 43 the yhousing y"17" is provided `with taperedtlireads 47 and the waterjacletii's provided with a tap bore adapted toreceive the part 47.

Referringto Figure y6 Ihave illustrated in`| diagrammatic `forrnthe useof my inven tion in conjunctionwith the well-known gravity feed.y In this connection it maybe said` that a tanlrDadapted tohold` gasoline or other fluidI ordinarilyl has anir hole so that gasoline will flow therefrom to the intake manifold. In utilizingmyfinvention-I have a pipe 48 joined to the vtank iD at the air hole "openingfi'n-sucha manneras'to completely seal i' the f parts surrounding the v air hole opening; said pipe 48finturn lead'-V ing to the cap nut-24. i As before stated, the means B may either hav'efthelug 43 or the part 47 having connection with the `water jacket 'c ofthe engine Then, if thewater reaches a' certainftemperature within` the water jacket' the valve in the means B will close and seal the opening in the tank and prevent iowl of gasoline ftherefroni'to,` the intake manifold. I' l 1 In Figure 5 I have illustrated a pressure system in'v lwhich the gasolinewithin a .tank

E is maintained under pressurei "Thel means B must bemodiliedjto operate withv saidV pressure system 4"andthe modified form is shown as B, and in which a pipe 49,1eajdsto an opening in the ytank E and in turn to the cap nut 24. 4Theinternal mechanism of the means B is reversed; that is to say, the

spring 32 is so yplaced as to at all times' keep the head seated upon the valve seat 28. The thermostat e is reversed in its position so that when it expands it forces the valve head 30 from the seat 28 and in so doing will allow the tank 'E to be yunder atmospheric pressure, whereupon the system will become inoperative. This mere reversal of parts in* the means B does not differ essentially from the means B, the p-rinciple of operation be-k ing the same. n

It is perhaps unnecessary to -state that the means B maybe connected with and operrender the said vacuum system ate iny conjunctionwith the filler plug of the temperature when the said devicey is yused Witlrn-a vacuum system, causes an y atmospheric .variation in said `vacuum systemto either opera-l tive or inoperative. .j f

' Anlinvention of this character would be adaptable for many uses other than for feeding gasoline or oil for automobile, and I do not wish to be understood as confining it to an automobile, as it -may be used in aeroplanes, tractors, and yin fact, anywhere that an internal combustion engine is utilized;v

It is obvious that many changes yand variations and modifications may bemade in departurefrom the particular description and showing of the accompanying drawing, .in adapting` the invention to varying` `conditions and requirements of use and service, without. departing from the true spirit of the invention. l
