ABSTRACT:
Apparatus for precision metering of selected amounts of fungible or granular material such as coffee consisting of a frame, a hopper supported by the frame having a large upper storage area and communicating with a small lower vertically oriented exiting trough, horizontal sliding plate extending below a forward lip of the exiting trough, the horizontal sliding plate having an edge contacting the extended rear lip and for moving the plate to traverse the rear lip during metering of the granular material, receptacle securably attached on an under side of the horizontal sliding plate, and the horizontal sliding plate cooperating with the rear lip during traverse of the horizontal sliding plate for filling the receptacle means by the rear lip causing the metering of the granular material on the sliding plate to dump into the receptacle. The forward lip is adjustable for controlling the magnitude of metering of the granular material. The horizontal sliding plate is spring biased for returning the sliding plate to a position for receiving the metering of the granular material. The horizontal sliding plate is essentially U-shaped for retaining the granular material heaped between the U-shaped sides, the rear lip and that portion of the forward lip disposed in position for the metering of the granular material together with a vertical member engaging at the forward end of the horizontal sliding plate. The hopper is constructed of a transparent material. The hopper is provided with a cover sheet. The forward lip is controlled by a knob to provide adjustability in controlling the magnitude of metering of the granular material. The hopper is removable from the frame. The horizontal sliding sheet is tensioned by a spring for positioning it in a forward position and urging it against a vertical member engaging at the forward end of the horizontal sliding plate.
