Abstract
A mechanical movement includes an input member movable in opposite directions, levers each connected to and pivotally movable by the input member, crank arms connected to and movable by the levers, eccentric crank pins driven by the crank arms, and circular gears connected to and rotated by the crank pins. The gears rotate an output shaft by engaging teeth on opposite sides thereof.
Claims6
A mechanical movement, comprising
- an input member movable in opposite directions along a given axis,
- a lever pivotally movable about a fulcrum which is perpendicular to and spaced from said given axis,
- means connecting said input member to a first point on said lever spaced a given distance from said fulcrum, to move said lever about said fulcrum and to move said first point relative to said given axis in response to movement of said input member,
- a circular gear having peripheral teeth,
- means mounting said gear for rotary movement about a gear axis which is substantially parallel to the axis of said fulcrum and is spaced from both the fulcrum and the given axis,
- a crank pin on said gear spaced from the gear axis,
- a connecting rod having one end pivotally engaging said crank pin,
- means pivotally connecting said connecting rod to a second point on said lever, the distance between the first point and the fulcrum being greater than the distance between the second point and the fulcrum,
- an output shaft lying parallel to said given axis and provided with external gear teeth which are in engagement with said teeth on said circular gear, whereby movement of said input member produces movement of said lever about said fulcrum to rotate said circular gear and rotate the output shaft.
