An automatic coffee-making machine comprising a grinder delivering ground coffee to a metering device storing a metered quantity of ground coffee and of releasing the metered quantity to a delivery chute displaceable from an inoperative position to an operative position above a fixed filter carrier in which is disposed a lower filter for the support of delivered ground coffee. The grinder is driven by a motor responsive to the delivery of a metered quantity of ground coffee to disconnect the motor from the grinder. A piston and cylinder arrangement delivers a measured quantity of hot water to the fixed filter carrier and is displaceable between a lower position to confine the ground coffee therein and to deliver hot water thereto and an upper position. The piston and cylinder arrangement is angularly displaced by camming surfaces responsive to the displacement between the lower and upper positions, and is displaced between the lower by a motor-driven linkage mechanism which also upper positions and displaces the lower filter to raise used ground coffee to an ejection position. The chute is angularly displaced by the piston and cylinder arrangement to the operative position in which it opens the metering device to receive and deliver the metered quantity of ground coffee to the fixed filter carrier in readiness for the next cycle of operation.
