1. A locking plate for use in an air turbine starter comprising: a lock plate body including an oil slinger extending away from a base, said base positioned on an outer peripheral surface of a clutch frame, and said slinger having a leading edge extending away from the base for a distance, and a ratio of said distance to a thickness of said base is between ten and thirty;said oil slinger having a cant angle, such that a downstream end of said oil slinger is at a greater distance from a side wall of said base than an upstream end of said oil slinger, said cant angle being between 1° and 25°, the upstream end of said oil slinger being positioned to be closer to the base than said downstream end, a tip angle defined along a tip of said oil slinger, and between said upstream end and said downstream end, said tip angle being between 5° and 60°; andsaid base having a bolt hole extending there through. 2. The locking plate as set forth in claim 1, wherein a ratio of a height to the downstream end of said oil slinger measured from the base to a length of said base is between 0.30 to 0.70. 3. The locking plate as set forth in claim 1, wherein there are two of said bolt holes extending through said base. 4. A clutch comprising: a clutch frame having an inner bore, and an outer peripheral surface, at least one bolt extending through a hole in said outer peripheral surface, and into said inner bore, said at least one bolt sandwiching a locking plate between a head of said bolt and said outer peripheral surface of said clutch frame, said bolt securing a spring within said inner bore, said locking plate including an oil slinger having a leading edge extending away from a base, said base being positioned on the outer peripheral surface, and said oil slinger extending radially away from a central axis of said clutch frame for a greater distance than the head of said bolt; andsaid clutch frame further mounting a pawl, said spring biasing said pawl in a rotational direction about a pivot pin; said oil slinger having a cant angle, such that a downstream end of said oil slinger is at a greater distance from a side wall of said base than an upstream end of said oil slinger, said cant angle being between 1° and 25°, the upstream end of said oil slinger being positioned to be closer to the base than said downstream end, a tip angle defined along a tip of said oil slinger, and between said upstream end and said downstream end, said tip angle being between 5° and 60°; and said base having a bolt hole extending there through. 5. The clutch as set forth in claim 4, wherein a ratio of a radius of said clutch frame to the outer peripheral surface from the central axis to a distance to an end of said oil slinger spaced furthest from said central axis from said base of said locking plate is between 3.0 and 4.5. 6. The clutch as set forth in claim 4, wherein said oil slinger extends radially away from a central axis of said clutch frame for a distance, and a ratio of said distance to a thickness of said base is between ten and thirty. 7. An air turbine starter comprising: a turbine rotor for selectively being driven within a housing;a clutch frame having an inner bore, and an outer peripheral surface, at least one bolt extending through a hole in said outer peripheral surface, and into said inner bore, said at least one bolt sandwiching a locking plate between a head of said bolt and said outer peripheral surface of said clutch frame, said bolt securing a spring within said inner bore, said locking plate including an oil slinger having a leading edge extending away from a base, said base being positioned on the outer peripheral surface, and said oil slinger extending radially away from a central axis of said clutch frame for a greater distance than a head of said bolt; said oil slinger having a cant angle, such that a downstream end of said oil slinger is at a greater distance from a side wall of said base than an upstream end of said oil slinger, said cant angle being between 1° and 25°, the upstream end of said oil slinger being positioned to be closer to the base than said downstream end, a tip angle defined along a tip of said oil slinger, and between said upstream end and said downstream end, said tip angle being between 5° and 60°; and said base having a bolt hole extending there throughsaid turbine rotor driving a clutch plate through a planetary gear system, and said clutch frame driving an output shaft for being utilized as a starter input to start a prime mover;said clutch frame further mounting a pawl, said spring biasing said pawl in a rotational direction about a pivot pin; andsaid pawls selectively engaging teeth in said clutch plate, such that said pawls can be biased out of said teeth to allow relative rotation between said clutch plate and said clutch frame, and biased into said teeth to cause said clutch frame and said clutch plate to rotate together. 8. The air turbine starter as set forth in claim 7, wherein a ratio of a radius of said clutch frame to the outer peripheral surface from the central axis to a distance to an end of said oil slinger spaced furthest from said central axis from said base of said locking plate is between 3.0 and 4.5. 9. A method of installing a locking plate with an integral oil slinger on a clutch frame in an air turbine starter comprising the steps of: (a) providing a clutch frame having a plurality of holes for receiving a locking plate;(b) placing a locking plate on an outer periphery of the clutch frame, and placing a spring within an inner bore of the clutch frame, and moving a bolt through the locking plate and the hole to secure the spring in the inner bore, the spring being positioned to bias a pawl; and(c) mounting said clutch frame into an air turbine starter such that the oil slinger will extend into oil within a housing for the air turbine starter, with the oil slinger extending away from a central axis of the clutch frame for a distance; providing said locking plate body with said oil slinger extending away from a base, said base positioned on an outer peripheral surface of a said clutch frame, providing said slinger with a leading edge extending away from the base for a distance, and a ratio of said distance to a thickness of said base is between ten and thirty; providing said oil slinger with a cant angle, such that a downstream end of said oil slinger is at a greater distance from a side wall of said base than an upstream end of said oil slinger, said cant angle being between 1° and 25°, the upstream end of said oil slinger being positioned to be closer to the base than said downstream end, providing a tip angle defined along a tip of said oil slinger, and between said upstream end and said downstream end, said tip angle being between 5° and 60°; and providing said base with a bolt hole extending there through. 10. The method as set forth in claim 9, wherein a clutch plate is formed with teeth, and is mounted within the inner bore, with the pawls engaging the teeth.
