MEANS FOR STARTING INTERNAL-COMBUSTION ENGINES.
Specification of Letters Patent. Application filed March. 21, 1908. Serial No.
Patented Sept. 19. 1911. $22,418.
" To all whom 'it may concern:
Be it known that I, Gorrnon HoNoLD,
5 Stuttgart, Germany, have invented certain new and useful Improvements in Means for Starting Internal-Combustion Engines; and I do herebydeclare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use tlie same. i
In starting multi-cylinder internal combustion engines which after an interruption are set in motion again merely by igniting the charge in one of the cylinders there exist two cylinders wherein at this moment there is a compression equal to half the normal compression, and thecylinder in which ignition ought to occur is that one the i ition plug of which is put into circuit the distributer. The common experience is, however, that the spark produced by" the battery and the coil does not suffice to ignite a mixture the compression of which .IS lOW, unless the sparks follow each other repeatedly and rapidly, whereas a single spark sufiices to i ite the mixture when the motor has once en started. It is therefore necessary, in starting the engine, to use a trembler such as is commonly employed when the ignition is by means of a battery or accumulator; whereas as soon as the engine is started the trembler may be ,5 dispensed with.
The present invention relates to the starting of multi-cylinder internal combustion engines by means of an ignition apparatus from a battery or 1e sparks sufiice for the ignition, and consists essentially in eflectin the ignition in the first instance with ai of a trembler in a known manner, and then efi'ectmg the ignitionby. single 5 s arks .when the engine has been started,
t e trembler being no longer in action. This method, compared with those commonly used for starting the en 'ne, in which the trembler is in action whi e the engine is running, presents the advantage that since single'sparks are used during the runnin the demand on the battery is considerab y less 'and' the electrodes of the ignition plug .are less used. Moreover, all the defects of i the trembler, which unfavorablcy affect the quality of theignition spark, 0 not come into play during running, so that the disadvantage inherent in the trembler, namely that it always requires a certain interval of time beforeit starts vibrating, which delay may retard the ignition at high speeds to an extent close upon an angle of' and gives rise to irregular working, is avoided.
In the accompanying drawings Figure 1 is a diagram illustrating the invention when the battery and coil are alone used for the i nition. Fig. 2 shows a modification of t e invention when both a battery and coil ignition and a magneto-electric ignition is provided. Fi s. 2, 2" and 2 are diagrams representing di erent positions of the controlling swltch. Fig. 3 is a transverse section through the circuit interrupter.
Referring to Fig. 1, 1 is the battery, 2 the coil, 3 the trembler electrically connected on the one hand with the battery and on the other through contact 4, which is normally, open with the body of the engine;
this contact 4 can be closed b a push button 5. It is a matter of inditi' erence which part of the trembler is connected with the battery and which with the mass of the engine'through the contact 4. Amechanicallydriven interrupter 6 and a condenser 7 are in parallel with the trembler. 8 is the distributing switch, 9 is the series of i ition plugs, and 10 is the switch for cuttmg off the ignition. The diagram re resents the parts in the position ready or starting. The contact 4 and the interrupter 6 are open, while the switch 10 is closed, and the ignition plug of that cylinder which is ready for ignitlon is in electrical connection with the distributing switch 8. As soon as the contact 4 is closed by pushing the'button 5, current flows through the trembler and the engine is started. The engine being set in motion, the interrupter 6 will be closed thereby and, the current through the interrupter and will not pass to the trembler which will remain inactive.
In Fig. 2, there is illustrated an arran ement in .which, in addition to theparts escribed with reference to Fi 1, there is used an "electromagnetic mac ine 11 provided with an interrupter 12 and a condenser v13 so that it can be brought into service when required. A controlling switch 14 is provided for the purpose of putting in or outof circuit either the batter system or-the magneto system. The di erent will then flow tributer 8 forms a part the magneto in such a boss 19 which, as
4 shown in Figs. 2 2", 2.-
positions of the switch for this purpose are The first of these is the position for connecting the magnetosystem with the ignition; the second is the osition for cutting out both systems; and the third is the position iior connecting the battery system with the ignition. It will be observed that no cut-out switch is here necessary, as one of the positions of the switch cuts out both systems; The common disinterrupter 6 may also be connected with a manner that apart from the magneto-electric machine no separate piece-of apparatus need be driven by the motor.
In Fig. 3, I have illustrated an interrupter which may be used and in which the circuit is closed by a spring and is positively opened by mechanical means. This interrupter is "open when the motor is at rest so that the disk, breaking the circuit, and thus causing a spark to pass at the moment that the boss 7 leaves the notch. The notched rotating disk magneto, but it may and in in parallel with the positively actuated cirrality of igniters, energy arranged is directly on the shaft of the be driven by gearing preferably from theengine.
Having now particularly described and ascertained the nature of my said invention what manner the same is to be performed, I declare that what I claim is 2- 1. In an ignition system for multi-cylinder engines, the combination, with a pluand a source of electrical to supply current to the igniters, of a positively actuated circuit intel-rupter arranged to interrupt the supply of current to the igniters, a normally inoperative trembler circuit breaker arrangedof the magneto. The
der engines,
the platinum contacts der engines, the combination,
cyllnder, a distributer and a cuit breaker and manually controlled means for rendering the trembler operative.
2. In an igniter system for multi-cylinder engines, the combination, with a plurality of igniters, a spark-coil, a magneto, electrical connections between the sparkcoil and theigniters, electrical connections between the magneto and the igniters, a trembler circuit breaker, and means for causing said trembler circuit breaker to interrupt the circuit from the spark-coil to the igniters, of a positively actuated circuit.
interrupter also arranged to interrupt the circuit from the spark-coil to the igniters,
said positively actuated circuit interrupter being in paral breaker, and a controlling switch arranged to switchwih'e igniters into circuit with either the spark-coil or the magneto, or to cut them out from both.
3. In an ignition system for multi-cylinthe combination, with a plurality of igniters, eluding the spark-coil and the igniters, and a positively actuated circuit interrupter arranged to control the said circuits, of a trembler circuit breaker, a normally open branch circuit in shunt around the positively actuated circuit interrupter, and
means for closing said normally open circuit temporarily. v 4. In an ignition system for multi-cylinwith an ig-' niter for each positively actuated interrupter, of a circuit in which the distributer and said interrupter are included, said circuit comprising branches leading from the distributer to the respective'igniters, of a source of electricity for energizing said circuit, a normally open shunt circuit around the positively actuated interrupter, an electro-magnetically operated circuit interrupter in said shunt circuit, and manually operated means for closing said shunt circuit. 4
