  • Patent number: 4708265
    Abstract: A practical and simple system that automatically measures and dispenses grain and powder type food products, such as sugar and flour contained within a canister type holder. The system consists of a drawer compartmentalized into precisely measured divisions with the topside uncovered and the bottomside selectively covered or uncovered by a moveable slide that allows for the pulling out of the drawer without spillage. The drawer will stop at one of several preset measured positions. These positions are controlled by a spring-pressured arm. With the drawer in a selected position the contents of the outward division or divisions of the drawer are dispensed accurately and immediately by pushing inwardly the moveable slide covering the bottom side. When the drawer is pulled outward an attached trailing horizontal upper slide prevents any of the contents within the canister from filling the empty area behind the drawer when the drawer is pulled out.
