Abstract
An apparatus for lifting and carrying articles having a support frame and carriage for transferring an article. The apparatus includes at least one first drive for converting rotational movement of a crank member into harmonic linear motion for lifting and lowering the carriage between a first position and a second position along a first path of travel. A second drive moves the carriage between a first position and a second position along a second path of travel.
Claims20
A harmonic lift and transfer apparatus comprising:
- at least one article transfer carriage;
- a frame supporting said carriage for movement along a first predetermined path of travel and a second predetermined path of travel wherein said second predetermined path of travel is transverse to said first predetermined path of travel including an elongate rail, a discontinuous lower rail portion attached to said elongate rail, said lower rail portion extends along said second path of travel and discontinues at said first and said second positions along said second path of travel;
- at least one first drive for converting rotational movement of said first drive into harmonic linear motion of said carriage along said first path of travel between a first position and a second position having a rotary crank member, a motor connected to said elongate rail for rotating said crank member about a fixed rotational axis, and a follower pivotally attached to said crank member radially spaced from said rotational axis;
- and
- a second drive for moving said carriage along said second path of travel between a first position and a second position.
