1. An electric igniter for explosive-engines comprising suitable electrodes, one of which is movable and is provided at its inner end with an arm carrying a contact-point, an arm connected to the outer end of said movable electrode, a trip-plate connected to said outer arm, a block connected to said trip-plate adjacent its outer end and a trip-rod arranged to engage the outer end of the trip-plate and to be released therefrom by said block.

2. An electric igniter for explosive-engines, comprising suitable electrodes, one of which is movable and is provided at its inner end with an arm carrying a contact-point, an arm connected to the outer end of said movable electrode, a trip-plate hinged to said outer arm, a spring for forcing said trip-plate normally toward said outer arm, a block attached to said trip-plate adjacent its outer end, a spring connected with said block to aid in restoring the movable electrode to normal position and a trip-rod arranged to engage the outer end of the trip-plate and to be disengaged therefrom by said block.

An electric igniter for explosive-engines comprising suitable electrodes, one of which is movable and is provided at its inner end with an arm carrying a contact point, an arm connected to the outer end of said movable electrode, a trip-plate extending from said outer arm and having a block attached to one side thereof, a trip-rod arranged adjacent said block and in position to engage the end of the trip-plate, said block serving to release the trip-rod from the trip-plate.

4. An electric igniter for explosive-engines comprising suitable electrodes, one of which is movable and is provided at its inner end with an arm carrying a contact-point, an arm connected to the outer end of said movable electrode, a trip-plate extending from said outer arm, a block fixed to said trip-plate adjacent its end, a trip-rod engaging said block and arranged in position to engage the outer end of the trip-plate and a spring for drawing said trip-rod normally toward said block.
