ABSTRACT:
An adjustable powder flow gate for a rotary pellet press has a movable gate wherein one dimensional motion of the gate across an opening in a powder flow feed frame on the rotating turret of the press is effected with a rotatable shaft having a screw connection to a member attached to the gate. The shaft is maintained in a selected rotational position with a bias member that is movable between an engaged and a disengaged position. The bias member is adapted to engage a selected detent on a member attached to the shaft having several circumferentially spaced detents when the bias member is in the engaged position. The shaft can freely rotate when the bias member is in the disengaged position. An operator can easily adjust the size of the opening by first disengaging the bias member from the selected detent, turning the shaft to move the gate to the desired position, and then engaging the bias member into a newly selected detent.
