Abstract
Abstract A pasta machine has an L-shaped base formed with an extruder seat and provided internally with a gear transmission having an input projecting in one direction from the base, and mixer and extruder outputs projecting in the opposite direction. An extruder body has an extruder chamber provided internally with an auger and is formed with a window opening radially into the extruder chamber. A mixer body has a mixing chamber secured to the extruder body and communicating with the extruder chamber through the window. This mixer body is provided internally with a mixing rotor that extends along and is rotatable about a mixer axis parallel to the extruder axis, and with a lid engageable over and closing the mixer body. The extruder body can be releasably interfitted with the extruder seat so as to fit the auger with the extruder output of the transmission and to fit the rotor with the mixer output of the transmission.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
350 words
A pasta machine comprising: a base formed with an extruder seat; a gear transmission in said base and having an input projecting in one direction therefrom, a mixer output exposed in the opposite direction therefrom, and an extruder output also exposed in said opposite direction and provided at said extruder seat; an extruder body having an extruder chamber provided internally with an auger element extending along and rotatable about an extruder axis, said body being formed with a window opening radially into said extruder chamber and with an axially open outlet; a mixer body having a mixing chamber secured to said extruder body and communicating with said extruder chamber through said window, said mixer body being provided internally with a mixing rotor element extending along and rotatable about a mixer axis generally parallel to said extruder axis, and with a lid engageable over said mixer body and displaceable between an open position giving access to the interior of said mixing chamber and a closed position blocking such access, said lid having a pair of portions substantially closing said mixing chamber in said closed position and defining a narrow slot too narrow to pass a finger through, whereby fluent ingredients can be poured through said slot into said mixing chamber but a user's finger cannot be inserted through said slot into said mixing chamber, said extruder body being releasably interfittable with said extruder seat with said auger element engaged with said extruder output and said mixing element being engaged with said mixer output; and means for preventing said lid from moving from said closed into said open position when said extruder body is interfitted with said extruder seat, said means including a lever pivoted at one end on said lid and guided on said mixer body, said mixer body being formed at said mixer axis with a throughgoing hole through which said mixer output engages with said rotor element when said extruder body is fitted to said base, said lever extending across said hole and being formed with a throughgoing hole aligned therewith only in said closed position of said lid.
Claim 2
Dependent Claim
350 words
A pasta machine comprising: a base formed with an extruder seat; a gear transmission in said base and having an input projecting in one direction therefrom, a mixer output exposed in the opposite direction therefrom, and an extruder output also exposed in said opposite direction and provided at said extruder seat; an extruder body having an extruder chamber provided internally with an auger element extending along and rotatable about an extruder axis, said body being formed with a window opening radially into said extruder chamber and with an axially open outlet; a mixer body having a mixing chamber secured to said extruder body and communicating with said extruder chamber through said window, said mixer body being provided internally with a mixing rotor element extending along and rotatable about a mixer axis generally parallel to said extruder axis, and with a lid engageable over said mixer body and displaceable between an open position giving access to the interior of said mixing chamber and a closed position blocking such access, said lid having a pair of portions substantially closing said mixing chamber in said closed position and defining a narrow slot too narrow to pass a finger through, whereby fluent ingredients can be poured through said slot into said mixing chamber but a user's finger cannot be inserted through said slot into said mixing chamber, said extruder body being releasably interfittable with said extruder seat with said auger element engaged with said extruder output and said mixing element being engaged with said mixer output; and means for preventing said lid from moving from said closed into said open position when said extruder body is interfitted with said extruder seat, said means including a lever pivoted at one end on said lid and guided on said mixer body, said mixer body being formed at said mixer axis with a throughgoing hole through which said mixer output engages with said rotor element when said extruder body is fitted to said base, said lever extending across said hole and being formed with a throughgoing hole aligned therewith only in said closed position of said lid.
Claim 3
Dependent Claim
39 words
The machine defined in claim 1, further comprising means for securing a pasta-shaping die over said outlet of said extruder body and a blade rotationally mounted on said auger and sweepable over said die to cut pasta issuing therefrom.
Claim 4
Dependent Claim
29 words
The machine defined in claim 2 wherein said auger element is provided with an axially extending screw extending through said die and securing said blade to said auger element.
Claim 5
Dependent Claim
39 words
The machine defined in claim 1 wherein said lever is L-shaped and has one leg formed with said hole and another leg formed with an elongated slot, said lid being provided with a pivot pin engaging in said slot.
Claim 6
Dependent Claim
51 words
The machine defined in claim 1, further comprising a gate between said bodies and formed with an aperture, said gate being displaceable between an open position with said aperture aligned with said window and a closed position with said aperture not aligned with said window and said gate blocking said window.
Claim 7
Dependent Claim
17 words
The machine defined in claim 5, further comprising a spring urging said gate into said closed position.
Claim 8
Dependent Claim
61 words
The machine defined in claim 6, further comprising means including a rotary knob for locking said bodies to said base, said knob being rotatable through a predetermined angular position for locking and unlocking said bodies, said gate and knob being formed with interengaging formations only permitting said gate to move between said positions in said predetermined angular position of said knob.
Claim 9
Dependent Claim
32 words
The machine defined in claim 1 wherein said mixer body includes a removable cover extending generally perpendicular to said axis, said rotor being seated in and axially nondisplaceable relative to said cover.
Claim 10
Dependent Claim
