An apparatus for producing coffee or other beverages has two brewing cylinders and brewing pistons which are movable in the brewing cylinders and which form a brewing chamber. A loading station is provided for loading the brewing chambers with ground coffee or the other media. One brewing cylinder can be moved in each case together with the associated brewing piston from a brewing position to the loading station and back again, wherein the associated brewing piston can be removed for the disposal of the used coffee or medium from the brewing cylinder. The second brewing cylinder can therefore be moved to the same loading station as the first, and this therefore results in a simplification of the design of the apparatus.

1. An apparatus for producing a beverage, comprising: a movable brewing cylinder having an open top and an open bottom;an upper brewing piston movable into and out of said open top of said brewing cylinder,a lower brewing piston movable into and out of said open bottom of said brewing cylinder, said brewing cylinder and said upper and lower brewing pistons when at least partly present in said brewing cylinder forming a brewing chamber,said apparatus defining a loading station in which said brewing cylinder is loadable through said open top of said brewing cylinder, while said upper brewing piston of said brewing cylinder is out of said brewing cylinder, with material for preparation of the beverage,said apparatus defined a brewing position in which the material loaded into said brewing cylinder is brewed,said brewing cylinder being movable, while said lower brewing piston is situated at least partly in said brewing cylinder, between said loading station and said brewing position,said lower brewing piston of said brewing cylinder being removable from said brewing cylinder to enable expulsion of the material from said brewing cylinder through said open bottom of said brewing cylinder; anda pivot arm connected to said lower brewing piston and that enables movement of said lower brewing piston into and out of said brewing cylinder;said lower brewing piston including a conduit communicating with said brewing chamber; andsaid pivot arm including a conduit communicating with said conduit in said lower brewing piston to enable brewed material from said brewing chamber to be conveyed out of said brewing chamber through said pivot arm. 2. The apparatus of claim 1, further comprising an additional movable brewing cylinder having an open top and an open bottom, an additional upper brewing piston movable into and out of said open top of said additional brewing cylinder and an additional lower brewing piston movable into and out of said open bottom of said additional brewing cylinder, and said additional brewing cylinder and said additional upper and lower brewing pistons when at least partly present in said additional brewing cylinder forming an additional brewing chamber, said additional brewing cylinder being movable between said loading station and said brewing position by a different movement means than movement means that cause movement of said brewing cylinder between said loading station and said brewing position. 3. The apparatus of claim 1, wherein said upper and lower brewing pistons are movable in an axial direction of said brewing cylinder. 4. The apparatus of claim 2, further comprising an additional pivot arm connected to said additional lower brewing piston and that causes movement of said additional lower brewing piston into and out of said additional brewing cylinder. 5. The apparatus of claim 1, further comprising movement means, additional to said pivot arm, for moving said lower brewing piston into and out of said brewing cylinder. 6. The apparatus of claim 1, wherein said upper brewing piston is movable by a different movement means than movement means that move said lower brewing piston such that said upper and lower brewing pistons are independently movable relative to one another. 7. The apparatus of claim 1, wherein said pivot arm causes movement of said brewing cylinder between said loading station and said brewing position when said lower brewing piston is at least partly in said brewing cylinder. 8. The apparatus of claim 1, wherein said brewing cylinder is vertically oriented. 9. The apparatus of claim 1, wherein said pivot arm moves said lower piston out of said brewing cylinder and away from a position below said open bottom of said brewing cylinder such that said upper brewing piston is then movable downward through said brewing chamber to expel the material out of said brewing chamber. 10. The apparatus of claim 9, further comprising a common drive that provides for movement of said lower brewing piston into and out of said brewing cylinder and pivotal movement of said lower brewing piston away from the position below said open bottom of said brewing cylinder. 11. The apparatus of claim 1, further comprising passages for connecting at least one grinding mechanism for the material to said loading station. 12. The apparatus of claim 1, further comprising an additional movable brewing cylinder having an open top and an open bottom, an additional upper brewing piston movable into and out of said open top of said additional brewing cylinder and an additional lower brewing piston movable into and out of said open bottom of said additional brewing cylinder, and said additional brewing cylinder and said additional upper and lower brewing pistons when at least partly present in said additional brewing cylinder forming an additional brewing chamber, only one of said brewing cylinder or said additional brewing cylinder being situated in said loading station and being loadable with material at a time. 13. The apparatus of claim 1, wherein said upper brewing piston includes a conduit communicating with said brewing chamber of said brewing cylinder. 14. The apparatus of claim 1, wherein said lower brewing piston is maintained in said brewing cylinder when said brewing cylinder is in said loading station and in said brewing station. 15. The apparatus of claim 1, wherein said upper brewing piston is maintained in said brewing cylinder when said brewing cylinder is in said brewing station. 16. The apparatus of claim 1, wherein said upper and lower brewing pistons are movable in an axial direction of said brewing cylinder and said brewing cylinder is configured to be movable in a direction perpendicular to the axial direction of said brewing cylinder. 17. The apparatus of claim 1, wherein said upper and lower brewing pistons are movable in an axial direction of said brewing cylinder and said brewing cylinder is configured to be pivotable about an axis parallel to an axis of said brewing cylinder.
