Abstract
Abstract This specification describes a differential-gearing unit having two input members and two output members that are interconnected by a spur gear and bevel gear arrangement. One of the inputs engages a ring gear that drives the carrier of the bevel gearing while the other input engages a pair of spur gears that drive the pinions of the bevel gearing. Input motion of the one input results in equal unidirectional motion of the two outputs while input motion of the other input results in equal but opposite motion of the two outputs. Simultaneous motion of both inputs results in a phase change between the two outputs.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
112 words
A differential-gearing arrangement comprising bevel gear means having a carrier member, a pair of bevel gears rotatably mounted on said carrier, a pair of bevel output gears meshing with said bevel gears and a ring gear secured to the outer periphery of the carrier; a pair of spur pinion gears drivinGly connected to said bevel gears; a circular rack engaging said spur pinion gears; and drive means engaging said ring gear; whereby motion of said drive means will cause said output bevel gear to rotate an equal amount in one direction, and linear motion of said circular rack will cause said bevel output gears to rotate an equal amount in opposite directions.
Claim 2
Dependent Claim
112 words
A differential-gearing arrangement comprising bevel gear means having a carrier member, a pair of bevel gears rotatably mounted on said carrier, a pair of bevel output gears meshing with said bevel gears and a ring gear secured to the outer periphery of the carrier; a pair of spur pinion gears drivinGly connected to said bevel gears; a circular rack engaging said spur pinion gears; and drive means engaging said ring gear; whereby motion of said drive means will cause said output bevel gear to rotate an equal amount in one direction, and linear motion of said circular rack will cause said bevel output gears to rotate an equal amount in opposite directions.
Claim 3
Dependent Claim
115 words
A differential-gearing arrangement comprising bevel gear means having a carrier member, a pair of bevel gears rotatably mounted in said carrier, a pair of bevel output gears meshing with said bevel gears and a ring gear secured to the outer periphery of the carrier; a pair of spur pinion gears drivingly connected to said bevel gears; a circular rack engaging said spur pinion gears; and rack gear means engaging said ring gear; whereby linear motion of said rack gear means will cause said output bevel gears to rotate an equal amount in one direction, and linear motion of said circular rack will cause said bevel output gears to rotate an equal amount in opposite directions.
Claim 4
Dependent Claim
115 words
A differential-gearing arrangement comprising bevel gear means having a carrier member, a pair of bevel gears rotatably mounted in said carrier, a pair of bevel output gears meshing with said bevel gears and a ring gear secured to the outer periphery of the carrier; a pair of spur pinion gears drivingly connected to said bevel gears; a circular rack engaging said spur pinion gears; and rack gear means engaging said ring gear; whereby linear motion of said rack gear means will cause said output bevel gears to rotate an equal amount in one direction, and linear motion of said circular rack will cause said bevel output gears to rotate an equal amount in opposite directions.
