A coffee grinding, portioning, and pressing device (10) includes a coffee bean storage container (20) and coffee grinding mills (24) located under the storage container. Coffee ground by the mills is delivered from the grinding mills (24) into a ground coffee collection chamber (40) and then passes from the collection chamber through a motor-driven pressing tool (50) directly into a detachable delivery filter (14) which is temporarily attached to the device. The shape and rotational motion of the pressing tool cause the ground coffee to be directed through the tool and into the filter container. The pressing tool (50), which is biased downwardly by a spring tensioning mechanism (70) that transmits force to the pressing tool (50) through a tensioning drive axle (74), incrementally and uniformly tamps the coffee into the filter container as the tool rotates. The accumulation of compressed coffee underneath the pressing tool (50) applies upward pressure against the spring tensioning mechanism (70) and causes the pressing tool to rise upwardly as the tool rotates. When the pressing tool (50) has moved upward a predetermined distance, a shut-off switch of a portioning control mechanism (80) is activated, ceasing the further addition of ground coffee. A volume portioning adjustment mechanism (84) modifies the amount of ground coffee that is compacted into the delivery filter.

[ The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:] [1.] A portioning and pressing device for compacting a preselected quantity of coffee, the device comprising:a pre-compaction chamber for delivering ground coffee into a container;a compaction mechanism located above the container and configured to consistently and incrementally tamp a preselected amount of ground coffee into the container as the coffee is delivered, thereby producing substantially uniform ground coffee density therethrough, wherein actuation of said compaction mechanism processes ground coffee through the compaction mechanism and incrementally tamps the ground coffee underneath the compaction mechanism into the container as a result of the downward biasing of the compaction mechanism; anda volume quantity dosing calibrator configured to shut off the compaction mechanism when the container has been filled a predetermined amount, by sensing when the compaction mechanism has been raised a preselected distance due to the accumulation of compressed ground coffee underneath the compaction mechanism, and then terminating the actuation of the compaction mechanism, thereby ceasing the flow of coffee.
