IGNITION TIMER CONTROLLING MECHANISM Filed NOV. 50. 1931 Adlance Patented Feb. 9, 1937 UNITED STATES PATENT OFFICE IGNITION TIMER CONTROLLING MECHANISM 6 Claims.
This invention relates to the spark control of an internal combustion engine and more especially to such control which is operated by the position of the carburetor throttle controlling mechanism and in a motor vehicle having an engine unit movably mounted with respect to the frame. Ordinarily, the spark position in an automotive vehi .e is manually controlled. In some cases, automatic advance governors have been produced but these depend upon increased throttle opening alone to provide the increased speed, which increased speed advances the spark.
It is the object of this invention to provide a spark advancing mechanism operated by the throttle control mechanism which will advance the spark as the throttle is opened and which will nevertheless provide a sufliciently retarded spark for proper idling of the engine, all of which is substantially unafiected by the relative movement of the engine unit and the frame.
I accomplish this object by providing a spring held contact connection between the carburetor throttle operating mechanism and the spark timer of the engine.
This is illustrated in the drawing in which:-
Figure l is a side elevation partly in section showing my spark and carburetor control applied to a movably mounted engine unit.
Figure 2 is a perspective view, with certain parts shown in section, showing the accelerator and carburetor throttle connections and one form of spring held contact connection between the throttle control and the timer, in a motor vehicle in which the engine unit may be mounted movably with respect to the frame.
Figure 3 is a plan view, with certain parts shown in section, of a slightly modified form of connection.
My present invention is shown in Fig. 1 as applied to a movably mounted engine unit, substantially as shown in my prior Patent No. 1,834,907, granted December 1, 1931, in which the engine unit A is carried by front and rear non-metallic resilient mountings B and C, respectively, which mount the same on the vehicle frame D so as to permit oscillatory movement of the engine unit relative thereto.
In the construction shown in Figure 2, which is a more or less standard automobile accelerator control construction, the accelerator pedal l is carried by the accelerator shaft 2 which may be mounted upon the frame or upon the body of the vehicle. Upon the shaft 2 is mounted an arm 3, to which is pivotally connected the rod 4. The rod 4 is pivotally connected to the carburetor throttle arm 5. The rod 1 is pivotally connected to a spark arm 6 on the shaft 2 and has the shoulder 8 thereon. The sleeve 9 is pivotally connected to the timer arm it and receives the end of the rod 1 and abuts against the shoulder 8 due to the normal action of the spring H whose ends are attached in any proper manner to resiliently draw the rod I and the sleeve 9 together. The adjustable stop screw l2 acts to stop the ad- Vance of the timer arm ill atthe point chosen as the maximum spark advance position.
It will be noted that due to the length of the arm 6, the spark timer arm in will strike the stop screw l2 as the accelerator pedal has moved the throttle arm 5 only a short distance, thereby opening the carburetor throttle but slightly. As the accelerator pedal i is further depressed in opening the carburetor throttle to its wide open position, the timer arm ill will continue to remain in contact with the adjusting stop screw I2 under the action of the spring H, the rod 1 meantime partially pulling out of the sleeve 9 and separating the shoulder 8 from the end of the sleeve 9. When the accelerator pedal 5 is allowed to rise, the throttle arm 5 strikes the adjustable set screw 14 which screw is set for the proper idling position desired for the carburetor throttle valve. As the carburetor throttle valve approaches this idling position, the shoulder 8 of the rod 1 will engage the end of the sleeve 9, after which the rod 1 and sleeve 9 will act as a single connection between the arm 6 and the timer arm 80 and further rising movement of the accelerator will retard the spark to the proper idling position. By connecting the rod l to the arm 6 at one of the several positions as indicated at E, and by proper setting of the timer l5, the set screw l2 and set screw I i, the desired inter-relation between the carburetor and the spark timing may be obtained. It will be seen that the spring H in this construction acts to assist the spring. l6 in resiliently tending to move the carburetor throttle controlling mechanism to the closed position, after the timer arm lil contacts the stop screw l2.
In the modification shown in Figure 3, the spring I l is used in place of the spring I l shown in the Figure 1. In this construction, the spring ll" however opposes the action of the spring I6 in its endeavor to move the mechanism to the closed throttle position, and although the construction shown in Figure 3 will operate, it requires the proper balance between the springs IS and II, and for this reason I prefer the construction shown in Figure 2.
