Loading apparatus

A loading apparatus for use in combination with a working machine comprising:

• an L-shaped mounting frame (6) having a vertical side and a horizontal side and fixedly connected to said working machine in vertical alignment and generally above the working position;
• a first quadric parallel link (21) having two spaced parallel rods (20), one end of each rod (20) being pivoted to the vertical side of said L-shaped mounting frame (6);
• a floating L-shaped parallel travel member (19) having a vertical side (19A) and a horizontal side (19B), said vertical side (19A) being pivoted to the other ends of said rods (20);
• a second quadric parallel link (50) having a primary rod (26) and a secondary rod (25) both being pivoted at one end to said horizontal side (19B) of said floating L-shaped parallel travel member (19);
• a holder arm assembly (49) pivoted to the other ends of said primary rod (26) and said secondary rod (25) and constituting one side of said second quadric parallel link (50), said holder arm assembly (49) including a venturi cap (29) operatively connected thereto for holding a workpiece (60);
• a coupling shaft (52) rotatably mounted to the horizontal side of said L-shaped mounting frame (6) through a bearing means (15);
• a first oscillating arm (51) pivotally connected at one end to said primary rod (26) of said second quadric parallel link (50) intermediate the ends of said primary rod (26) and at the other end to one end of said coupling shaft (52);
• an electric motor (54) with a reduction gear (11) fixedly connected to the vertical side of said L-shaped mounting frame (6) through a bracket (7), said reduction gear having an output shaft (12);
• an intermediate arm (57) disposed generally below said electric motor (10) and pivotally connected to the vertical side of said L-shaped mounting frame (6) through a shaft (56);
• a crank arm (55) pivotally connected at one end to said output shaft (12) of said reduction gear (11);
• a first rod (58) pivotally connected at one end to the other end of said crank arm (55) and at the other end to said intermediate arm (57) intermediate the ends of said intermediate arm (57);
• a second rod (59) pivotally connected at one end to the extreme end of said intermediate arm (57);
• and
• a second oscillating arm (53) pivotally connected at one end to the other end of said second rod (59) and at the other end to the other end of said coupling shaft (52);
• whereby pivotal movements of said first rod (58) and said second rod (59) cause an amplified pivotal movement of said second oscillating arm (53) relative to the pivotal movement of said intermediate arm (57).
