Abstract

594,392. Ratchet clutches. SOC. ANON. DES USINES CHAUSSON. July 12, 1945, No. 17850. Convention date, April 11, 1944. [Class 80(ii)] [Also in Group XXVII] In order to prevent ignition on reversal of an internal combustion engine the drive of the rotor shaft of the ignition head or distributor comprises a shaft in two parts the lower part positively engaging and driven by the crank shaft of the engine and the upper positively engaging or formed integral with the rotor shaft the two parts of the shaft being held in engagement under spring pressure and formed with engaging means operable to cause a positive drive from the lower part to the upper in the normal direction of rotation only of the engine. As shown a crankshaft 2 drives a shaft 16 through a worm 3 and helical pinion 4. A coupling element 17 on the shaft is urged by a spring 22 against a second coupling element 10 on the ignition head shaft 9. In the normal direction of rotation notched helical surfaces on the elements engage and the. shaft 9 is driven. The coupling element 17 rotates with the shaft 16 by reason of a pin 21 in the shaft engaging slots on the element. When the engine rotates in reverse the coupling element 17 slides along the shaft 16, the pin 21 sliding in the slots, and spring 22 is compressed by the riding up on one another of the helical surfaces on the elements. Thus the ignition cam is not driven and ignition does not take place. Two or more notches may be provided in the helical surfaces and the shaft 16 may be driven by means other than the worm and pinion such as by gears.
