W1 YYVESSES W. N. PARK. CONTROLLING MEANS FOR COMBUSTION ENGINES.

' APPLICATION FILED DEC. 20, 1910.

Patented Oct. 15, 1912.

, f UNITED STATES PATENT onmon.

To all whom it may concern:

Be it known that 1, WILLIAM N. PARK, a citizen of the United States, residing at Corning, in the county of Steuben and State of New 'York, have invented certain new and useful Imprqvements in Controlling Means for Combustion-Engines; and I do hereby declare the following to be a full, clear, and exact'description ofthe invention, such as will enable othersqski-lled in the art to which it appertains to make and use the same.

My invention relates to new .and useful improvements in controlling means for combustion engines and my object is to provide means for advancing or retarding the sparking mechanism in the motor.

Aafurther object is to provide a governor and connect the same to the driving shaft of the engine, and,

'20 A further object is to provide means for connecting the commutator disk to the governor, whereby said disk will be operated to advance or retard the action of the sparking mechanism by the action of the governor,

Other objects and advantages will be hereinafter referred to and more particularly pointed out in the'specification and claim.

In the accompanying drawings which are made a part of this application, Figure 1 80 is a die ammatic view of the governor and means or attaching the same to the commutator disk, and, 2 is a sectional view 'as seen on line 2-2 1g. 1.

Referringto the drawings in which simi- 85 let reference numerals designate corresponding parts throughout the several views, 1 indicates the commutator shaft which is constructed in the usual 91 any preferred form and 2 indicates a circuit reaker adapted to cooperate with parts of the commutator.

Surrounding the shaft 1 is the commutator disk 3, which is likewise constructed .in the usual or any preferred form and has 4 around its periphery contact points 4, which are adapted to cooperate with the circuit breaker.

The form of commutator herein shown is designed to be used in connection with a four-cylinder engine, thereby requiring four ontact points for obtaining the proper ignition of the gases and as the speed'of the engine varies at different times, it becomes necessary to advance or retard the point of ignition or the time of making the spark. When using a stationary ignition point,

CONTROLLING 'MEANS FOR CONfBUSTION-ENGINES.

the gas would-be eXplodedat-thesame time i whether the engine was runningat two .hun-

dred and fifty revolutions per minute'or at three hundred and fifty revolutions per 50 minute so that at the-higher speed, the gas would not be exploded at the highest point of compression, but would be delayed until after this point had been passed, in which event the engine does not develop its full 5 power. To this end, therefore, I provide my improved means for'advancingor retarding the oint of ignition, whereby the explosion wi 1 always occur at the point of highest compression, thus relieving the crank shaft and bearings of the extra strain occasioned by improper ignition. In accomplishingthis result, the is provided with an ear 5, to which is attached one end of a' link 6, the opposit'e end of the link being attached to one arm 7 of a bell;crank lever 8, the opposite arm 9 of the Lbellcrank lever being attached to a itman 10, thebell crank lever being pivotal y mounted to any suitable object or part of the engine.

One end of the pitman 10 is bifurcated form a yoke 11, the ends of which extendon opposite sides of a head'12, said head havin a circumferential groove 13, into whic extend rollers 14 carried by the ends of the yoke. The head 12 is slidably mounted upon a shaft'15 and in order to cause the head to rotate with the shaft and at the same time permit the head to move longitudinally thereof, the shaft is provided with a channel 16, into which extends a rib 17. on the head. The channeled end of the shaft 15 is provided with a ri id stop collar 15 for limiting the outwar movement of the head 12.

One end of the head 12 has attached thereto spring arms 1.8, the opposite ends of said 5 arms being 'attached'to a collar 19, which collar surrounds the shaft 15 and is adjustably attached thereto b means of a' set screw 20. By means of t e set screw 20 the entire governor consisting of the head 12, collar 19 and connecting arms 18 may be ad justed longitudinally of the shaft 15, while the movement of said governor upon'said shaft is limited by the stop collar 15.

The head, spring arms and shaft upon form of lubricant retaining medium may be.

which the head is mounted serve as a governor and the shaft is connected to the crank shaft of the engine in any suitable manner,'

as by providing a cog 22 on the shaft 15 and connecting said cog with a similar gear (not shown) attached to the crank shaft of the engine. I

placed and communicating with the cavities -is a port 24; through which the oil may be Copies of this patent may be bhtained for live cents each, By addressing the "Commissioner of Patents,

introduced into the cavities.

In operation when the engine is first started, the speed thereof is naturally at a low point so that the contact points will be turned to such point as to cause the spark or ignition coincident to the cylinder of the engine reaching its highest oint of compression and as the speed 0 the engine graduallyincreases, the spring arms 18 will be extended and the head moved downwardly, which will result ii -rocking the bell crank lever and gradually moving the position of the contact point with respect to the circuit breaker, thus gradually advancing the point ofignition as the speed of the en g ne'mc'reases m which event the point of ignition is always maintained at a proper position to explode the gases'when the piston of the engine has reached its highest point of compression. It will likewise be .seen that as thespeed the engine decreases, the contact points of the COmmUf tator will be properly adjusted to retard the ignition thus adapting in connection with an 'en speed the engine may attain.

It will further" be seen that in view offthe. simplicity of the device, it can be readily A7 evice f r 5 gme at what??? I attached to the engine and at a expense.

It will further be understood thatthisde vice can be used in connection with all forms of engines using a gaseous exploding product for propelling theengine.

What I claim is An attachment for engines comprising} shaft having one end thereof channeled, a head slidably mounted on the channeled end of said shaft and rotatable therewith, acol- .lar.m0unted on said shaft,. meansjfon'adjustably securing said collarlofigitudina-lly of saidshaft, spring arms connectedatop '5 posite ends to said head and collar; weights carried centrally of said spring arms, and a rigid stop collar carried by the end of said shaft for limiting the outward movement of said head. v

In testimony whereof I havesigned'my name to this specification in the 'presence'of two subscribing witnesses.
