IGNITER FOR GASOLENE-E'NGINES.
Applicationfiled February 16, .1906, Serial No. 301,342.
To all whom it may concern:
Be it known that we, DANIEL F. MAC- CARTHY and HARRY M. DARLING, citizens of the United States, residing at, respectively, Wlnte Bear and St. Paul, in the county of Ramsey and State of Minnesota, have in.
vented certain new and useful Improvements in I niters for Gasolene-Engines, of which the following is a specification.
Our-invention relates to improvements in igniters for gasolene engines, its object being to provide a more positively acting igniter than the ordinary make-and-break or jump spark.
To this end our invent-ion consists in the features of construction and combination hereinafter particularly described and claimed.
In the accompanying drawings forming part of this speclfication, Figure 1 is aside view of our improved igniter partly broken away and showing the wiring conventionally; Fig. 2 is a section on line of Fig. 1, and Fig. 3 is a face view of the contact disk forming part of the invention.
In the drawings 2 represents the governor shaft of a four cylinder engine. Secured upon the governor shaft as by means of screws 3 is a disk 4 of suitable conducting material with a non-conducting facing 5. Projecting inwardly through the facing 5 from the outer edge of the disk 4 is a contact lug 6.
7 represents a lever arm of non-conducting material loosely mounted upon the governor shaft and held against the lnner face of the disk 5 by a collar 8. The collar 8 is suitably supported u )011 the shaft as by means of the screws 9. lidable in sleeves 10 fitting in openings through the lever 7 at a distance from the shaft 2 equal to that of the contact lug 6 are blocks 12, each having a concaved inner face into which loosely fits a ball 13. The free ends of springs 14 secured by screws 15 to the outer edge of the lever, bear against the outer ends of the blocks 12. The secured ends of the springs carry binding posts 16. As shown in Fig. 1 the posts 1 6 are connected by wiring through a spark coil box 17 with the ordinary spark plugs 18 of the engine. The wiring, spark coil box and spark plu s beingthe usua parts of an ord1 nary gasoIene engine, are merely shown conventionally. The lever 7 may e secured in Specification of Letters Patent.
Patented June 29, 1909.
adjusted position in connection with a suitable rack 19'to advance or retard the s ark.
In operation the disk will rotate wit the shaft 2, the lever 7 standing in thedesired adjusted position. As the lug 6 passes over the balls 13, the primary circuit will be made through the disk 4, contacting ball 13, block 12, binding post 16and by the connected wiring through the spark coil box and battery. This will affect the secondary circuit of the spark plug in the ordinary way to make a spark. Each complete rotation-of the shaft 2 and disk 4 will thus successively affect the circuit-s of the four spark plugs to explode the charges in the four cylinders of the engine. The spark may be advanced or retarded by adjusting the lever 7m connection with the rack 19.
While in the drawings the ignitcr is shown arranged for a four cylinder engine it will be apparent that it can be used for a one or more cylinder engine of two or four cycle type by using the appropriate number of contact blocks 12, and connected spark plugs. Also the disk 4 and lever may be mounted upon the governor shaft as shown, or upon any other equivalent rotating part.
We claim:
1. An igniter of the class described comprising in combination with a rotary shaft, a non-conducting disk supported upon said shaft, a contact electrical connected with said shaft and extending through the side face of said disk, a non-conducting rocker arm p votally supported upon said shaft against the side face of said disk, a contact block extending through and projecting from the face of said arm into the path of the contact carried by said disk, and a contact spring bearing against the outer end of said block.
An electric igniter of the class described comprising in combination witha rotary shaft, a non-conducting disk fixed upon said shaft, a contact electrically connected with said shaft and extending through the side face of said disk, a non-conducting rocker arm pivotally supported upon said shaft against the side, face of said disk, a spring pressed contact block extending throu h said arm, and a contact ball carried by tie end of said block and projecting from the face of said arm into the path of the contact carried by said disk.
