ABSTRACT:
A dispenser for bales of hay, comprising a fixed frame defining a plurality of compartments each adapted to receive a bale or part of a bale of hay. A front door closes all the compartments. A trap door is mounted for vertical swinging movement below each compartment about a horizontal axis on the frame between a raised position in which the trap door serves as a bottom for the compartment and is adapted to support a bale of hay in the compartment, and a lowered position in which the bale of hay is dispensed from the bottom of the compartment. A rod is mounted for rotation on the frame about an axis parallel to the horizontal axis. A lug on the trap door is engageable with a lug on the rod when the rod is rotated to a first position, the lugs being out of engagement with each other and the trap door free to fall when the rod is rotated to a second position. A retainer releasably retains the rod in the first position. A solenoid has a plunger which is moved upon actuation of the solenoid. Responsive to movement of the plunger, the retainer is disabled, thereby to permit the lug on the trap door to press downward and disengage from the lug on the rod thereby to rotate the rod the first position to the second position and to permit the trap door to fall open to dispense the bale or part bale of hay. A timer selectively predetermines the time of actuation of the solenoid.
