The barrier includes apertures that facilitate extrusion of dough material by the piston through the bather. The dough extruder further includes a handle section including a handle and a plurality of gear members coupled to the handle and to the piston, where the handle is movable with respect to the piston support, and a base to support the extrusion section and the handle section. The gear members couple with the handle and piston to facilitate movement of the piston away from the base and toward the bather when the handle is moved in a direction toward the base. ## Claims ### Claim 1 An extruder for extruding a dough material, the extruder comprising: an extrusion section comprising: a piston support; a bather disposed at an end of the piston support and including apertures; and a piston telescopically movable within the piston support toward the barrier, the piston configured to facilitate extrusion of dough material through the barrier; a handle section comprising: an arcuate member disposed around at least a portion of the piston support and movable with respect to the piston support; and a plurality of gear members coupled to the arcuate member and to the piston, and a base to support the extrusion section and the handle section, wherein the gear members couple with the arcuate member and piston to facilitate movement of the piston away from the base and toward the barrier when the arcuate member is moved in a direction toward the base. ### Claim 2 (depends on 1) The extruder of claim 1, wherein the arcuate member is an annular member that surrounds the piston support. ### Claim 3 (depends on 1) The extruder of claim 1, wherein the arcuate member comprises at least two individual arcuate members, wherein each individual arcuate member is disposed around at least a portion of the piston support. ### Claim 4 (depends on 4) The extruder of claim 4, wherein each of the individual arcuate members is coupled to a separate gear member. ### Claim 5 (depends on 1) The extruder of claim 1, wherein the gear members are angularly spaced apart from each other such that all of the gear members are equidistant from each other. ### Claim 6 (depends on 1) The extruder of claim 1, wherein the piston support has a interior cross sectional area which is substantially filled by the piston, such that the piston remains telescopically movable with respect to the piston support while preventing dough material from moving past the piston in the piston support. ### Claim 7 (depends on 6) The extruder of claim 6, wherein the piston support is cylindrical. ### Claim 8 An extruder for extruding a dough material, the extruder comprising: an extrusion section comprising: a piston support; a bather disposed at an end of the piston support and including apertures; and a piston telescopically movable within the piston support toward the barrier, the piston configured to facilitate extrusion of dough material through the barrier; a handle section comprising: an annular member that surrounds the piston support and is movable with respect to the piston support; and a plurality of gear members coupled to the annular member and to the piston, and a base to support the extrusion section and the handle section, wherein the gear members couple with the annular member and piston to facilitate movement of the piston away from the base and toward the bather when the handle is moved in a direction toward the base. ### Claim 9 (depends on 8) The extruder of claim 8, wherein the gear members are angularly spaced apart from each other, such that all gear members are equidistant from each other. ### Claim 10 (depends on 9) The extruder of claim 9, wherein the plurality of gear members comprises three gear members angularly spaced 120 degrees apart. ### Claim 11 (depends on 8) The extruder of claim 8, wherein the gear members are rotatably coupled to the annular member. ### Claim 12 (depends on 8) The extruder of claim 8, wherein the gear members are movably coupled to the piston. ### Claim 13 (depends on 12) The extruder of claim 12, wherein the gear members include teeth configured to movably couple the gear member to the piston. ### Claim 14 (depends on 13) The extruder of claim 13, further comprising: a plurality of support members coupled to an exterior of the piston support and configured to facilitate the coupling of the gear members to the piston, each support member including two plates spaced apart from each other so as to form a gap for receiving one of the plurality of gear members, wherein the gear members and the plates are configured to allow the teeth to move the piston. ### Claim 15 (depends on 8) The extruder of claim 8, wherein the piston is at an uppermost position when the handle section is in a lowermost position, and when the piston is in its uppermost position, an upper end of the piston is substantially coplanar with an upper end of the piston support. ### Claim 16 (depends on 8) The extruder of claim 8, wherein the piston is at a lowermost position when the handle section is in an uppermost position, and when the piston is its lowermost position, an uppermost end of the piston is separated from an upper end of the piston support, such that a gap is formed therebetween. ### Claim 17 An extruder for extruding a dough material, the extruder comprising: an extrusion section comprising: a piston support; a bather disposed at an end of the piston support and including apertures; and a piston telescopically movable within the piston support toward the barrier, the piston configured to facilitate extrusion of dough material through the barrier; a handle section comprising: an arcuate member disposed around at least a portion of the piston support and movable with respect to the piston support; and at least three gear members coupled to the arcuate member and to the piston, and a base to support the extrusion section and the handle section, wherein the gear members couple with the arcuate member and piston to facilitate movement of the piston away from the base and toward the bather when the handle is moved in a direction toward the base. ### Claim 18 (depends on 17) The extruder of claim 17, wherein the barrier is removably securable to the piston support. ### Claim 19 (depends on 17) The extruder of claim 17, wherein the barrier and the piston support include threads configured to removably secure the bather to the piston support. ### Claim 20 (depends on 17) The extruder of claim 17, wherein the base includes at least one storage compartment.
