Charge Forming Device for Gas Engines
|
James A. Charter |
Chicago, IL |
Abstract:
This invention relates to the art of internal combustion engines, and pertains more especially to an improved mechanism for forming and governing the explosive charges admitted to the engine-cylinder.
One object of the invention is to provide an improved device of the character stated, which will facilitate the running, of the engine alone or under light load with an economy of fuel, and prevent the stoppage of the engine through lack of sufficient fuel supply on occasions when the load is suddenly removed and the governing slide is practically closed to prevent the engine from racing.
Another object of the invention is to provide a means whereby the action of the centrifugal governor which controls the governing slide for the charge may be varied, so as to exert a greater or less closing action upon said slide under a given engine speed.
Claims:
1. In a charge-forming mechanism for engines, the combination with a mixing chamber having an air supply passage leading thereto and an oil supply nozzle projecting therein, of a valve controlling the communication of said mixing chamber with the induction passage of the engine, and a tube carried by said valve, said tube extending inwardly of the mixing chamber in a direction at right angles to said oil supply nozzle to a point adjacent to the delivery end of the latter and exerting a local suction thereon when the valve is closed, substantially as described.
2. In a charge-forming mechanism for engines, the combination with a mixing-chamber communicating on one side with the induction passage of the engine and on the other with the atmosphere, of an oil supply nozzle projecting upwardly into said mixing chamber, means for maintaining a supply of oil in said nozzle at a height below the delivery end thereof, a governor controlled slidable grid-valve between said mixing chamber and induction passage, and a tube carried by said valve and extending inwardly of the mixing-chamber, said tube being so mounted in the valve that when the latter is closed its outer end communicates with the induction passage while its inner end lies adjacent to the delivery end of said nozzle, producing a local suction effect upon the oil in the latter, and when said valve is opened, said tube is without substantial effect upon said delivery nozzle, substantially as described.
3. In a charge-forming mechanism for engines, the combination with a mixing-chamber formed with an air-supply passage, and communicating with the induction passage of the engine, of an oil-supply nozzle projecting upwardly into said mixing chamber, means for maintaining a supply of oil in said nozzle at a height below the delivery end thereof, a valve between said mixing chamber and induction passage, a tube carried by said valve and extending inwardly of the mixing chamber whereby to produce a local suction effect upon the delivery end of said nozzle when said valve is closed, a governor mechanism connected to and operating said valve according to the speed of the engine, and means for opposing the closing movement of said valve, substantially as described.
4. In a charge-forming mechanism for engines, the combination with a mixing chamber formed with an air-supply passage, and communicating with the induction passage of the engine, of an oil-supply nozzle projecting upwardly into said mixing chamber, means for maintaining a. supply of oil in said nozzle at a height below the delivery end thereof, a valve between said mixing chamber and induction passage, a tube carried by said valve and extending inwardly of the mixing chamber whereby to produce a local suction effect upon the delivery end of said nozzle when said valve is closed, a governor mechanism connecting to and operating said valve according to the speed of the engine, and adjustable elastic means for opposing the closing movement of said valve, substantially as described.

Electric Igniter for Gas Engines
|
James A. Charter |
Chicago, IL |
Abstract:
This invention relates to the art of explosive engines, and has reference more particularly to a new and improved ignition mechanism for firing explosive charges admitted to the engine cylinder.
My present improvements are embodied in that type of ignition mechanism employing relatively fixed and movable electrodes in the explosion chamber of the engine, a magneto of the oscillating armature type, and electric connections between said magneto and electrodes.
One of the principal objects of the invention is to provide a simple mechanism whereby the ignition can be adjusted or timed properly to the engine cycle while the engine is in motion, This is a very desirable feature, since with different fuels, different the rates of speed, etc., the point of explosion must be varied in relation to the position of the crank at the time the explosion is produced.
Another object of the invention is to provide an igniter mechanism which will permit the positive starting of the engine from a stand-still, using the current from the magneto which is regularly used when the engine is running, an preventing any danger of the engine reversing or starting to run backward when starting up.
Claims:
1. In an igniter mechanism for gas engines, the combination, with a pair of separable electrodes, and a magneto for supplying current thereto, said magneto having an oscillatory armature, of a pendulum arm fast on said armature, a link connecting said pendulum arm and movable electrodes through a pin-and-slot connection permitting movement of said link in one direction without actuating said-electrode, a spring opposing the turning movement of said armature and, when tensioned and released, effecting a return swing of said pendulum arm past the neutral position of said armature whereby to separate said electrodes, a rotary shaft adjacent to said magneto, a disk rotatable but confined against endwise movement on said shaft, a trip carried by said disk and adapted to engage and swing said pendulum arm thereby tensioning said spring, and hand-operated means operable While the engine is running to shift said disk in either direction around said shaft, substantially as described.
2. In an igniter mechanism for gas engines, the combination with a pair of normally closed separable electrodes, spring-actuated mechanism for separating said electrodes, of a rotary shaft, a disk on said ,shaft having a hub, a trip pivoted on the face of said disk ,and having a tailpiece, a spring normally holding said trip with its nose projected beyond the periphery of the disk and its tail-piece in contact with said hub, whereby said trip is adapted to contact with and tension and then release said electrode-separating mechanism when traveling in a forward direction, but is depressible When traveling backward, a manually operable lever, means actuated by said lever for adjusting said disk in either direction around said shaft, and means for locking said lever in set position, substantially as described.
3. In an igniter mechanism for engines, the combination with a pair of normally closed separable electrodes, a magneto and for supplying current thereto, and a spring connected to said key, a quadrant plate provided with a plurality of holes, and a spring catch carried by said lever and adapter to engage any one of said series of holes to secure said lever in set position, substantially as described.
