ABSTRACT:
A receptacle having a floor with parallel slots to receive and collate screws in a collating section and to queue them in a queuing section of the slots which has an intersecting escapement for depositing screw individually into receivers. The receptacle reciprocates to tip the slots downwardly in one slot direction and then the other. A retainer overlying the queuing section excludes loose screws and retains the queued screws in the slots during tipping. The retainer moves away from the slots when the receptacle is tipped downward toward the collating section to permit displaced screws to clear to the collating section. A gate at the leading edge of the retainer closes off the margin between the retainer and the floor to entry under the retainer of loose screws outside the slots. Screw conduits leading from the escapement reciprocate with the receptacle and connect with stationary receivers through articulations. Detents or recesses in the queuing sections detain the queues of screws from sliding away from the escapement when the receptacle is tipped downward in the direction away from the escapement.
