To all whom it may concem:
Be it known that'l ULivnR J. Barns, a citizen of the United States, residing at Tilton, in the county of Poweshiek, State of Iowa, have invented certain new and useful Improvements in Igniter-Gears for Explosive-Engines; and I do hereby declare the following to be a full, clear, and exact de- -scription of the invention, such-as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to igniter gear for explosive engines.
In. certain types of explosive engines, wherein a governor is provided for opening the exhaust and keeping it open when the engine is running above a certain speed, no means is provided for eliminating the spark during the time the exhaust is being held open and. it is therefore the object of my invention to provide such means.
The invention is embodied in a simple mechanism which is arranged in operative relation to the igniter trip rod of the engine and is operated by the valve rod, when the said rod is moved to position to hold the exhaust open 'under conditions mentioned above, to lift the igniter trip rod and thereby eliminate the spark which would otherwise result.
In the accompanying drawings, Figure l is a side elevation of an explosive engine of the ordinary type showing the application of my invention thereto, Fig. 2 is a top plan view thereof, Fig. 3 is a detail side elevation of a portion of the engineoand of the mechanism embodying my invention the several elements of the said mechanism being shown in normal position, Fig. 4L- is a similar view fposition assumed by the several elements 0 the mechanism when the speed of the engine has reached an abnormal the valve rod by the numeral 12, and the igniter trip rod by 13. As is usual, the valve rod is operatively connected with the rocker 14 which is oscillated by the rotation of the cam 15 carried by the shaft 16 which is in turn driven from the engine shaft which is indicated by the numeral 17. The igniter trip rod is oscillated by reason of an eccentric connection 18 had with the shaft- 16 and rests adjacent its free end upon the usual roller 19 which is mounted to rotate upon the ordinary stud bolt 20 upon the side of the engine cylinder, it being understood that when the engine is in operation, the outer or free end of the said rod 13 describes substantially a circle and that at-each cycle, it trips the igniter electrode 11. It iswith the engine mechanism so far described that the controlling mechanism embodying my invention is associated and the said controlling mechanism will now be specifically described.
A. triangular rocker 21 is mounted for oscillatory movement upon the stud bolt 20 and lies outwardly of the igniter trip rod and journaled upon this rocker adjacent one corner thereof is a small roller 22 which at all times lies beneath the igniter trip rod. The lower end of the rocker extends to one side of the valve rod of the engine and upon the said valve rod is fixed a stud or pin 23 which is designed to engage with the edge of the rocker 21 and oscillate the same under conditions which will now be explained.
As is usual in an engine of this general type, when the speed thereof reaches-an abnormal degree, the valve rod 12 is shifted to position to open the exhaust by mechanism actuated by a governor, the latter being shown at 24, and is locked in this position until the speed of the en me has decreased and when the valve rod 1s so shifted, the rocker 21 is oscillated or rocked to the position illustrated in Fig. 4 of the drawings thereby bringing the roller 22 into engagement beneath the igniter trip rodand raising the same so that its free end will not engage with the igniter electrode 11. It will.
be understood, of course that sparking is in this manner eliminated until the speed of the engine assumes a normal degree.
What is claimed is: In an igniter gear for internal combustion engines, the combination with an igniter trip rod, and a governor controlled valve rod; of a rocker having means engageable with the trip rod to move the same out of the path of the electrode, and a'pin on the valve rod for actuating the rocker, said valve rod, rocker and pin being mounted and arranged to move the trip rod out of the 10 path of the electrode While the valve rod is in position to hold open an exhaust valve.
In testimony whereof, I afiix my signature, in presence of two Witnesses.
