7 AUTOMATIC SPARK-CONTROLLING: MEANS. J
Application filed Novcmber,11, 1925. Serial No. 68,4 i5.
tion is to provide automatic means for preventing jerking of the motor of an automotive vehicle when the car is running atlowspeed.
The invention preferably includes means for automatically retarding the spark when the motor is running at low speed, The
mechanism by which I effect such automatic retardation preferablyjncludes an operating mechanism for the distributor controlled directly from an accelerator rod. J
Specific objects of the invention are to provide a. simple and practical mechanism by which movement-of the accelerator rod may be transmitted to the distributor, so that the/spark will be automatically advanced and retarded as the speed of the engine is accelerated or decreased; to provide mechanism which maybe readily attached to any standard make of automobile; mechanism.
, which may be manufactured with compara; tive economy; which will not materially increase the power necessary to pedally operate the accelerator rod; and mechanism which will be rugged, durable and efficient in use." I With the above noted and other objects 1n,view, the invention consists 1n certain primary object of the present inven "12 is operated through the medium 'of a.
crankarm 14 by the accelerator rod 15, the accelerator rod having a ball and socket con. nection 16- with the crank arm. The invention as thus far described may be entirely conventional, such mechanism or its equivalent being used on all standard'makesof automobiles for controlling the speed-of the' en ine, the accelerator rod 15 being usually operated by-a ped al (not shown). The present invention is more particularly concerned with the provision of means for automatically advancing the sparkas the throttle valve 13 is opened, and retarding the spark as the throttle valve 13 is closed. The distributor 17 is rotatably mounted to turn with support 17, this support having bolted theretoas at 17 the down offset extensions 18 of a bearing plate 18 carrying. a stud 19 which serves as a fulcrum for a cam plate 20 having a cam slot 21 therein. The plate 20 is fulcrumed intermediate its ends,-and at its lower end is'p-ivotally connected to one'end of an'operating rod 22.
The other end of the operating. rod has a 8 ball and socketconnection 23 with suitable link mechanism 24 conected to the crank arm 14. Thus, as. the accelerator rod is moved in either direction, motion is trans novel features of construction and combina mitted directlythrough the operating rod 22 tions and arrangements of parts, as will b more fully hereinafter set forth and pointed out inthe claims. The invention maybe more. fully understood from the following description in connection with the accom-' panying drawings, .wherein Fig. 1 1s a diagrammatc view in side elevation, showing a carburetor, a distributor, and the mechanism by which the accelerator rod controls the distributor. The distributor is shown in retarded position.
Fig. 2 is a view similar to Fig. 1, but showing the position of the parts when the distributor hasbeen moved to. advance the "spark.
Fig. 3 is an enlarged detail on the line In the drawings I have usedthe reference character 10 to designate the carburetor of an automotive vehicle, this carburetor being bolted to the intake manifold 11 inthe usual manner. =Twelve- (12). is the rock shaft mounting the butterfly valve indicated at dotted lines 13 which controls the admission of fuel to the manifold. The rock shaft i vancing the spark. It will also be noted that the longer arm of'slot 21, after the roller has reached the position of Fig. 2, will have no effect, except a holdingJ effect on J the roller, the longer arm of the slot merely 19 providing clearance for movement .of the plate as the accelerator rod is operated at high speeds of the engine.
By virtue of the foregoing construction,
the spark will-be initially advanced as the 0 a .speed of the engine is initially increased, and after the enginehas reached a normalrunning speed, no further movement of -the roll.- cr will be had, the rear end of slot 21 simply providing clearance for further movement 1 of the accelerator red." It will also be noted that as the accelerator rod is shifted to the left as in Fig. 1, throttling down the engine,
the spark will be automatically retarded. so that there will be no jerking or knocking of the. engine at low speeds.
. variations.
It will be understood that the mechanism which I have employed to carry out the invention is subject (to a wide variety of The means for instance, by which I mount-the cam plate on the dis tributor, may be considerably varied. Any
' appropriate linltage might connect the operating rod 22 to the accelerator15. In fact numerous changes and alterations might be made in the general form and arrangement of parts described, without departing from the invent on. Hence I do not wish to lim t myself to the details set forth, but shallcon- I sider myselfat liberty to make such changes and alterations as fairly fall within the- 1 spirit and scope oflthe'appended claims! "Iclaim' I 1. In an engine, a distributor and a 'controlling arm projecting radially therefrom,
a controller plate acting on the controlling arm, means for controlling the acceleration of the speed of the engine, operatively connected to said controller plate, said controller plate having a: slot therein receiving the controlling arm,-
2. The combinatlon with a distributor having an ar projecting radially therefrom, of a plate iulcrumed' intermediate its ends adjacent the distributor, and having a cam-slot therein co-actin ally from the distributor and working in an approximately L shaped cam' slot inthe controller plate.
4. In tlIlriIH-tOlDOtlVQ engine, tl e combination with an accelerator'rod for-regulating the speed of the engine, and a distributor including a radially projecting arm, of a plate fulcrumed intermediate its ends adjacent the distributor, and having a cam slot The combination with a distributor ro- 35 with the arm, and
therein, coacting with the arm, and means operatively directly connecting the accelerator rod with the plate whereby the spark is advanced or retarded as the speed of the engine is accelerated or reduced. 3
