Movable supporting device for milking apparatus

A movable supporting device for milking apparatus having a milking claw, said device comprising:

• a vertical support column;
• a first pivot means including a collar surrounding said support column and a vertically positioned plate unit attached thereto;
• a pair of parallel spaced arms one end of each of which is connected to said plate unit to pivot about horizontal axes;
• a spring angularly connected between said parallel arms;
• a second pivot means connected to the other end of each of said parallel arms;
• a third arm one end of which is connected to said second pivot means so that said third arm is horizontally disposed;
• a fourth arm one end of which supports said milking claw;
• and
• a third pivot means connected between said third and fourth arms so that said fourth arm is horizontally disposed;
• said third and fourth arms being maintained in said horizontally disposed position regardless of movement of said parallel arms.

A movable supporting and automatic retraction device for milking apparatus having a milking claw, said device comprising:

• stationary support means;
• first pivot means mounted on said stationary support means;
• first movable means including a pair of spaced arms connected at one end to said pivot means;
• second pivot means connected to the other end of said spaced arms;
• linking arm means having one end connected with said second pivot means and the other end receiving and supporting said milking claw whereby said apparatus may be readily moved;
• first actuating means for causing said first movable means to be moved in a first predetermined direction;
• and
• second actuating means for causing said first movable means and said linking arm means to be moved in a second predetermined direction substantially normal to said first predetermined direction whereby when actuated said first and second actuating means cause said arms to be automatically retracted.

A movable supporting and automatic retraction device for milking apparatus, said device comprising:

• stationary support means;
• first pivot means mounted on said stationary support means;
• first movable means including a pair of spaced arms connected at one end to said pivot means;
• second pivot means connected to the other end of said spaced arms;
• linking arm means having one end connected with said pivot means and the other end adapted to receive and support predetermined milking apparatus whereby said apparatus may be readily moved;
• first actuating means for causing said first movable means to be moved in a first predetermined direction;
• second actuating means for causing said first movable means and said linking arms means to be moved in a second predetermined direction substantially normal to said first predetermined direction whereby when actuated said first and second actuating means cause said arms to be automatically retracted;
• and
• means for limiting movement in said first predetermined direction until a predetermined amount of movement has occurred in said second predetermined direction, said limiting movement means including a rod actuated by said movement in said first predetermined direction and a cam mechanism for causing the resumption of said movement in said first predetermined direction after predetermined movement has occurred in said second predetermined direction. pg,32

• a vertical support column;
• a first pivot means including a collar surrounding said support column and a vertical plate unit attached thereto;
• a pair of parallel spaced arms one end of each of which is connected to said plate to pivot about vertical axes;
• a spring angularly connected between said parallel arms;
• a second pivot means connected to the other end of each of said parallel arms;
• a third arm one end of which is connected to said second pivot means;
• a fourth arm one end of which supports said milking claw;
• a third pivot means connected between said third and fourth arms with said third and fourth arms being maintained in a horizontal position regardless of movement of said parallel arms;
• a first hydraulic cylinder for causing said arms to be moved upwardly in a vertical direction when said first hydraulic cylinder is actuated;
• a second hydraulic cylinder connected with one of said arms to cause said arms to be rotated about a horizontal axis when said second hydraulic cylinder is actuated;
• and
• limiting means for limited upward vertical movement of said arms after a predetermined amount of movement has occurred until after a predetermined amount of rotational movement has occurred whereby when said hydraulic cylinders are actuated said arms of said device are automatically lifted and retracted in a predetermined manner.
