Torque divided hydraulically proportioned output differential

Claim 1

A DIFFERENTIAL COMPRISING A PAIR OF OUTPUT SHAFT, A SPUR GEAR MOUNTED ON EACH OF SAID SHAFTS, A DIFFERENTIAL CASING ROTATABLY MOUNTED ON SAID OUTPUT SHAFTS A PLURALITY OF PINS ROTATABLY MOUNTED WITHIN SAID CASING, A FIRST SERIES OF PINION GEARS REMOVABLY SECURED TO SAID PINS AND MESHING WITH SAID SPUR GEARS, A SECOND SERIES OF PINION GEARS, CERTAIN OF SAID SECOND SERIES OF PINION GEARS BEING REMOVABLY MOUNTED ON CERTAIN OF SAID PINS, CERTAIN OTHER OF SAID SECOND SERIES OF PINION GEARS BEING REMOVABLY MOUNTED ON CERTAIN OTHER OF SAID PINS AND MESHING WITH SAID CERTAIN OF SAID SECOND SERIES OF PINION GEARS TO FORM A MECHANICAL GEAR TRAIN DRIVE, PRESSURE OPERATED MEANS FOR INTRODUCING HYDRAULIC FLUID SELECTIVELY AGAINST SAID FIRST SERIES OF PINION GEARS AND SAID SPUR GEARS TO CREATE A PARTIAL LOCK, SAID PRESSURE OPERATED MEANS INCLUDING A SERIES OF AUTOMATIC SPRING-LOADED DIRECTIONAL FLOW CONTROL VALVE ASEMBLIES, EACH VALVE ASSEMBLY HAVING A GENERALLY HOLLOW CYLINDRICAL PISTON, SPRING MEANS FOR URGING SAID PISTON TOWARD CLOSED POSITION, A RETAINING BRACKET FOR SAID SPRING, A SOURCE OF HYDRAULIC FLUID, AND FLUID PORTS CONNECTING SAID SOURCE OF HYDRAULIC FLUID WITH SAID VALVE ASSEMBLIES, WHEREBY WHEN ONE OF SAID SPUR GEARS ROTATES MORE RAPIDLY THAN THE OTHER OF SAID SPUR GEARS THE PRESSURE WILL BE ALTERED AND CERTAIN OF SAID VALVE ASSEMBLIES WILL OPEN TO INTRODUCE HYDRAULIC FLUID AGAINST
