PURPOSE:To be able to stop ignition operation at an optional set time by installing circular plates in such a way that a circular plate is fixed to a ignition plug and at the back side of this plate a circular plate closely contacting and rotating with the plug is placed and at the front of the fixed plate a circular plate starting to rotate with the back side plate at a specified time only is installed. CONSTITUTION:A circular plate F is put on a center shaft of a circular plate B and is fixed to rods E, E' of an ignition plug and is placed as a fixed circular plate. A circular plate G which is put on the center shaft is strongly pushed to the inner wall surface of an outer peripheral projecting part K of the plate F by the tip parts J, J' of spring mechanisms H, H' and the plate G is coupled with the plate F. Further, the projections D, D' of the plate B are aligned with two holes M, M' at the back side of the plate G and then the plate G and B are united and a spring wound watch type timer is attached at the outer periphery of the projection K. At the specified time, the projections I, I' are pulled back by the action of a mechanism integrated into the timer and the tip parts J, J' are separated from the projecting parts K and the plate G is rotated to a ignition stop position by two springs P, P' between the plate G and F and therefore, the plate B is also rotated to stop ignition. |
