Description: |
| Abstract:
This invention relates to igniting devices for explosive engines; and it consists in certain improvements in the construction thereof, as will be hereinafter fully described, and pointed out in the claims, The ignition is effected in this apparatus by an electric spark, and the apparatus is designed to simplify and make more efficient devices of this character.
Claims:
1. In an igniting device for explosive-engines, the combination with the cylinder part; electrodes arranged within said cylinder part; means for completing an electric circuit through said electrodes; an oscillating rod extending through said part and carrying one of said electrodes; means outside of said cylinder part for oscillating said rod for breaking contact; means actuated by the pressure of exploded gases for momentarily locking said rod against a return movement; and means for breaking the circuit while said-rod is momentarily locked against the return movement.
2. In an igniting device for explosive-engines, the combination with the plug A; the electrodes C and B arranged on the inner end of the plug; means for completing an electric circuit through said electrodes; the rod C2 extending through the plug and having the arms C' thereon for carrying the contact points C; the shoulder c on said rod engaging said plug; means for rocking the rod C2 for breaking the contact between the electrodes C and B, said rod C2 being free-to move axially to permit the shoulder C' to be brought into frictional contact with the plug A to lock the rod against a return movement; and means for breaking the electric circuit while the rod is locked against the return movement.
3. In an igniting device for explosive-engines, the combination with the electrodes; a movable means carrying one of said electrodes; devices for delivering a hammer-blow to said means to break the contact; rotating mechanism comprising a ratchet-cam for actuating said hammer device; and means imparting movement to said rotary mechanism.
4. In an igniting device for explosive-engines, the combination with the electrodes; a movable means carrying one of said electrodes; devices for delivering a hammer-blow to said means to break the contact; a ratchet-cam; the teeth of which in their movement actuate and release the hammer devices; and a reciprocating bar and pawl therein operating upon the teeth of said ratchet for rotating the same step by step.
5. In an igniting device for explosive-engines, the combination with the electrodes; movable means carrying one of said electrodes; a lever E for moving said movable means; a spring F actuating the lever E; the lever G forming a hammer device and arranged to deliver a hammer-blow to the lever E to break the contact of the electrodes, said lever G being influenced to this movement by the spring F; the ratchet-cam H having the teeth h adapted to operate the lever G; and the reciprocating part J and the ratchet pawl k carried with the lever J and acting upon the teeth of the ratchet for moving the same.
6; In an igniting device for explosive-engines the combination with the electrodes C and B the oscillating rod C2 having the arm C' carrying the electrode C; the plug A on which said parts are mounted; the lever E mounted on the rod C2; a hammer-lever G pivotally mounted and arranged to deliver a hammer-blow to the lever E to break the contact between the electrodes C and B; the spring F for actuating the lever G and lever E, the lever G to deliver the blow and the lever E to return the electrodes into contact; the cam-ratchet H arranged. to operate the lever G as it is rotated; and a moving part for rotating the cam-lever H.
7. In an igniting device for explosive-engines, the combination with the electrodes C and B the oscillating rod C2 having the arm C' carrying the electrode C; the plug A on which said parts are mounted; the lever E mounted on the rod C2; a hammer-lever G pivotally mounted and arranged to deliver a hammer-blow to the lever E to break the contact between the electrodes C and B; the spring F for actuating the lever G and lever E, the lever G to deliver the blow and the lever E to return the electrodes into contact; the cam-ratchet H arranged to operate the lever G as it is rotated by a moving part for rotating the cam-lever II; the rod C2 having a shoulder c thereon free to be forced into frictional contact with the plug by the pressure of exploded gases and to lock the parts against a return movement.
8. In an igniting device for explosive-engines the combination with the electrodes; a movable means carrying one of said electrodes; spring-actuated devices for delivering a hammer-blow to one of said means to break the contact; means controlled by the exploded gases for momentarily holding the electrodes out of contact; and means for breaking the circuit during the time that the electrodes are locked out of contact.
