United States, and both residing at "Lake- 6-wood-, in the countyof Cuyahoga and State- J of 0hio, have invented a certain new and useful Improvement-in Circuit-Controllers, of which the following is a full, clear, and exact description. i This invention, in .the -,formin which itadapted for use on a motor car driven by an internal combustion engine having a-plu-- rality ofcylinders, and employlng an-induction coil ignition system, as a means for prodncingproperly timed. sparks inthe several ylinde s. 1 a

may. be'produced in the respective-engine Icylindersfto prolong the life of the distrib-. uting imechanism by both making and break mg and timingmechanism; and'generally to render the device efiicient and practical for-the stated purpose' a -v Q In the drawing, Figure 1 is a central sec- I tional' sideel'ev'ati'on ofa "deviee einbd yin'g a the inventiomoand a diagrammatic view'of 9 the induction coil, its circuits, etc. 2

The device" includes a small case made of insulating material, a'shaft rotatably mounted therein, and parts car;

ried andsupported by said shaft and-case. Said shaft is indicated by A, and itis rotatably mounted in ametallic sleeve b'which is fixed to the outer face of the end B of said case. This shaft A is to be fixed to the end of a shaft-G by any'suitablemeans, as,' for example, an ordinary sleeve coupling 1 Application aied-april'za, 1909. Serial 1m. 491,444

so-calledspark lever of theinotor. ,Through mechanism said case is prevented "from; 1

rotating while the shaft 'A rotates, but perside of the same. This timerincludes two' mits the case to be turned a little so as to advance or retard the spark. It is clear that. during each rotatidn' of shaft A the head 0 comes successively into contactwith:

.the vielding-contact" devices, i. e. the fourballs Zr, thereby successively completin the secondary circuit to the several spark p u'gs'.

It will lie-understood that the type of spark I metallic plates R, R fixed to the inner face of. the end plates B, and insulated from each other. vThe' terminals of the primary coil are connected 'bywires Z, 'Z, with these plates by means of binding posts r r On the plate R- is a'hoss a which supports the adjustable contact screw M. A lever F is pivoted to plate It and extends from itspointof support toward-the shaft-A. It

is under the influence of -a spring Stending to swing it away from the screw Fixed to thelever F is 'a small flat contact spring f a finger f which lies in front of the inner p W thereto," and" pro ects into the path of the carrying a: contact stud 7'' located opposite.- the end of the screw M. Theinneren'd'of the lever F ext-ends under the inner end of this spring, and is then bent back to; form end of the spring f. 'A-hammer lever is'=als0 pivoted to the plate R and extends inward from its point of support toward. the shaft and in such position that its inner; end may be engaged by the four tappets n on, a ring N which embraces and normally rotates with said shaft A; A spring 14) acts to swing this leverl toward the lever F and into engagement with a fixed stud r which limits the spring inducedmovement of said I lever. ,;Fixed. to the lever is a finger w which projects past the Stud 1'' and into engagement with the lever F. As the shaft rotates the tappets n successively strike the lever \V and swing it to the position shown 'in Fig. 2,,and then release' 'it' to the action of its spring 10. The lever flies then the left striking the -lever F a smart blow which swings said lever F "also to the left and thereby brings the stud j" against the end.

of the screw M. The lever F will'continuey to swing to the left after this contact has been made, the spring f bending as this" is happening until the spring S OVQX'COIIIOS the momentum of the lever F,.stops it and then swings it in the opposite direction. In movingin this directionthe finger f engaging with the inner end of the fiat spring f draws it to the right and separates the stud f from the contact screw M. While these contacts are closed, however, theprimary (is circuit is closed, and thereupon an induced 10 plugs illustrated is that in which the sparkcurrent is produced in the secondary coil. K'Vhen the primary circuit is'broken by-the separation of the contacts f and M the secondary circuitbeing closed, a spark will be produced fin-fthe cylinder which then hap- It is to be noted that the timer operates e of the arm 6 isin contact with one of the 'balls k", and also that the circuit of the primary coil is broken before the head 6 leaves its contact-with thisball, There is, therefore, vIre-sparkingv or burning between the head and any of the balls k because these are-never brought into "engagement or separated whilet-he secondary. current is flowing-.3

The tappets n are projections upon a ring N rotatably mounted upon a-m'etallic sleeve Q fixed tothe-insulat'ing shaft section D. A spring pawl 15 supported by this; metallic sleeve engages with one ,or the other of the tappets, and, when-the shaft A is going in with the shaft} '\Vlien,}however, the shaft is turned in the opposite direction, the tappets present a beveled face for contact with saidv pawl andtherebyl rpu'shthe same back without turning saidring.; The pawl: as shown is a; pin with a beveled end which scribed. v p
