Abstract
That uses the weight of an electric car (1) that runs along a lopsided lever (2), that is, a lever that is larger one side than on the other, with a chain (3) fastened to the smaller side, to transfer the force generated by the weight of the car (1) when it is at the end of the larger side of the lever (2) to a main shaft (5) that moves clockwise and, in turn, moves a return counterweight (8) linearly.
Claims4
A two-way linear/dynamic force Multiplying device, comprising:
- a support,
- a lever having two opposite ends and pivoted at a point intermediate said two opposite ends on said support,
- a counterweight car movable along said lever, said counterweight car having an electrical motor for driving said counterweight car along said lever,
- a return counterweight movable between a raised position and a lowered position,
- a latch for releasably latching said return counterweight at said lowered position,
- a ratchet rotatably mounted to said support by a main shaft,
- a pulley rotatably mounted on said support adjacent said ratchet, and
- a chain having one end connected with one end of said lever and extending around said ratchet and said pulley and having an opposite end connected with said return counterweight.
