ELECTRICAL IGNITING DEVICE FOR INTERNAL-COMBUSTION ENGINES.
Specification of Letters Patent.
Application filed August 6, 1913.
Patented Aug. 25, 1914. Serial No. 783,341.
Be it known that I, EUGENE GAHSMANN. a citizen of Germany, and a resident of the borough of Brooklyn, county of Kings, and State of New York, have invented a certain new and useful Improvement in Electrical Igniting Devices for Internal- COmbustion Engines, of which the followin is a complete specification.
Tt is Well known in the art, that in electrical igniting devices for internal combustion engines the point of ignition must be advanced or retarded according to the variations in the speed of the engine, and that such ignition devices are usually equipped with mechanism for effecting this auto matically, the speed of the engine is increased or reduced. This mechanism to be effective, must be constructed so as to be highly sensitive, and prompt to respond to every change in speed.
The mechanism is actuated by variations in the speed of a rotating part of the il'nition device. which, as a rule. is driven by a transmission from the engine. and as the speed of the internal combustion engines, used on automobiles, motor boats. etc., is very much more affected by changes in the load than the speed of other engines, which can be constructed heavier in proportion to the power to be produced, it is, consequently, much more abruptly and frequently reduced and increased, and the operation of the mechanism for advancing or retarding the ignition point. correspondingly of an automobile, motor boat, etc. engine. will be so much more frequent and rapid. The most frequent changes in the speed of these engines, take place at the starting of the engine, and before the vehicle. or boat, gets fairly under Way, and during such periods, the ignition point; regulating devices are kept in a constant state of more or less violent vibration, much more so than when the engine is run at higher speeds than its calculated normal. Furthermore, while the engine runs at such low speeds the rotating of the magneto shaft is influenced by the alternating resistance and attraction of the pole pieces by the field magnets, these alternating factors tending in one instance to retard. and in the other, to accelerate as rotation. This interference is practically nullified when the engine is run at its normal speed or above, while the ignition point regulating device is caused to act most fretpiently during the period from the starting of the engine, and before its normal, or higher, speed is attained, though the economically efficient running of the engine may not, and in most engines does not, require the changing of the ignition point during the period.
The efforts, heretofore made, to obviate the detrimental effect thereof by providing variously constructed cushioning devices, were successful only in reducing the noise, and only for a brief period of time. but are wholly ineffective to remedy the cause and main defect, the vibrating and the con sequent wearing out of the parts of the regulating device, and the impairing, in fact, destroying, of its efficiency. The stated consideratii'ins show that the harm incring and caring, out of the parts of the mechanism, can only be obviated by the prevention of the almost constant changing of the ignition point, ba k and forth, during this period at low speeds, but so that. the capacity of the device for regulating, that is, advancing and retarding of the ignition point. when the engine is run at the higher speeds, is not impaired.
Taking into consideration the fact. that internal comhustion engines of average con struction do not require the ignition point to be advanced during the increase in their speed from zero to nearly the calculated normal. and will work and run satisfacttr rily when making a higher or lower number of revolutions per minute within the stated range. I have devised means for automatically arresting the operating parts of the ignition point regulating device. during the periiids. in which the engine runs at speeds below a predetermined limit, and again automatically releasing them when the speed of the engine rises above it, the arresting, holding, and again releasing of these operatin parts being always effected automatically )y the variations in the speedof the engine. By these means the object of my invention, to relieve the operation of the ignition point regulatin devices of the stated defects, is aecolnplisied.
The practical embodiment of my invention in the construction of an operative device are based upon the stated considera- 'tions anti the construction of the herein shown and described automatic locking attmrhmem fur six-ch 1 1113mm f the:

Extended tests of the device, herein shownand described, in practical use, have demonstrated that a locking device, constructed upon the stated principles, attains the objects of my invention in every respect, and does not, in any way, impair the effectiveness of the device for automatically advancing or retarding the ignition point, wherewith it is combined.
