Abstract
Abstract A distributor for use with an electronic breakerless ignition system. The distributor has a triggering rotor and a triggering sensor which are connected by a bearing to form a single assembly so that the radial spacing between the rotor and sensor remains constant regardless of any variation in the axis of rotation of the rotor.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
90 words
For use in a conventional distributor having a breaker cam and a timing mechanism, a unitary assembly for converting the distributor to use with an electronic breakerless ignition system comprising a triggering rotor, means adapted for mounting said rotor on the cam for support and conjoint rotation, a triggering sensor, means adapted for connecting said sensor to the timing mechanism, and a bearing connecting said rotor and sensor for relative rotation and supporting said sensor from said rotor and maintaining a substantially fixed radial relationship between said rotor and sensor.
Claim 2
Dependent Claim
90 words
For use in a conventional distributor having a breaker cam and a timing mechanism, a unitary assembly for converting the distributor to use with an electronic breakerless ignition system comprising a triggering rotor, means adapted for mounting said rotor on the cam for support and conjoint rotation, a triggering sensor, means adapted for connecting said sensor to the timing mechanism, and a bearing connecting said rotor and sensor for relative rotation and supporting said sensor from said rotor and maintaining a substantially fixed radial relationship between said rotor and sensor.
Claim 3
Dependent Claim
37 words
An assembly as set forth in claim 1 wherein said triggering rotor includes a plurality of arms arranged so that the tips of said arms pass in close proximity to said sensor during rotation of said rotor.
Claim 4
Dependent Claim
42 words
An assembly as set forth in claim 1 wherein said triggering rotor includes a plurality of arms, each arm having a slot arranged so that during rotation of said rotor said sensor intercepts said slots as said arms sweep past said sensor.
Claim 5
Dependent Claim
76 words
For use in a conventional distributor having a breaker cam, a unitary assembly for converting the distributor to use with an electronic breakerless ignition system comprising a triggering rotor, means adapted for mounting said rotor on the cam for support and conjoint rotation, a triggerng sensor, and a bearing connecting said rotor and sensor for relative rotation and supporting said sensor from said rotor and maintaining a substantially fixed radial relationship between said rotor and sensor.
Claim 6
Dependent Claim
76 words
For use in a conventional distributor having a breaker cam, a unitary assembly for converting the distributor to use with an electronic breakerless ignition system comprising a triggering rotor, means adapted for mounting said rotor on the cam for support and conjoint rotation, a triggerng sensor, and a bearing connecting said rotor and sensor for relative rotation and supporting said sensor from said rotor and maintaining a substantially fixed radial relationship between said rotor and sensor.
Claim 7
Independent Claim
99 words
A method for converting a conventional distributor having a breaker cam, a timing mechanism and a breaker point plate assembly to use with an electronic ignition system comprising the steps of removing the breaker point plate assembly from the distributor, mounting on the breaker cam a unitary assembly having a rotor, a sensor and a bearing connecting the rotor and sensor for relative rotation and maintaining a substantially fixed radial relationship between said rotor and sensor, said mounting being such that the rotor is connected to the cam for conjoint rotation, and connecting the sensor to the timing mechanism.
