Actuator mechanism for continuous roll baling machine

Claim 1

In a roll baling machine having lower bale forming means, a first upper bale forming means cooperating with said lower bale forming means to define a first bale forming chamber, a second upper bale forming means cooperating with said first upper bale forming means to define a second bale forming chamber; arm means movable into a lower position for moving said first upper bale forming means into a first position where material is prevented from entering said second bale forming chamber, said arm means movable into an upper position for moving said first upper bale forming means into a second position where a roll bale may be transferred from said first to said second bale forming chamber, and said arm movable into an intermediate position for moving said first upper bale forming means into a third position where material is allowed to enter said second bale forming chamber while a roll bale is maintained in said second bale forming chamber by said first upper bale forming means; said arm means carrying guide members engaging said first upper bale forming means, said arm means being positioned in said lower, upper and intermediate positions when said first upper bale forming means is in said first, second and third positions, respectively, ramp means movable between an operative position extending upwardly above said lower bale forming means and an inoperative position; the improvement comprising actuator means interconnecting said arm means and said ramp means causing movement of said ramp means to the operative position when said arm means moves to said lower position, and said actuator means also causing movement of said ramp means to the inoperative position when said arm means moves to said upper and intermediate positions.
