- said housing upper portion carrying said incremental-movement power-drive ingredients dispenser, said ingredients dispenser including plural ingredients containers carried upon a turntable member rotational on said upper housing portion, and incremental power drive means for driving said ingredients dispenser for dispensing ingredients from said ingredients containers into said brew pot via said aperture in response to incremental rotational motion of the turn table member, said power drive means including:
- a reversible motor;
- a gear rotating in respective opposite directions in response to respective forward and reverse operations of said motor;
- a toggle member pivoting between respective first and second positions in response to rotation of said gear in respective opposite directions;
- said toggle member carrying a first pinion meshed with said gear and driving a second pinion;
- said toggle member also carrying a third pinion meshed with said gear, and driving a fourth pinion via a direction-reversing drive, said second pinion and said fourth pinion being spaced circumferentially apart relative to said turn table member;
- said turn table member peripherally defining a gear section divided into plural respective gear sectors by plural circumferentially spaced apart intervening notches having no gear teeth; and
- in each of said first and said second positions of said toggle member said second and said fourth pinions respectively meshing with a gear segment of said turn table member to rotate said turn table member in a single direction regardless of direction of operation of said motor until the meshed pinion runs off a gear segment into a notch to stop rotation of said turn table member, continued operation of said motor in the same direction with a pinion in a notch not rotating said turn table member;
- whereby, reversing direction of operation of said motor pivots said toggle member to the other of said first and second positions, and meshes the other of said second and fourth pinions with a gear segment to again rotate said turn table member in said single direction regardless of direction of rotation of said motor; and
- a programmable controller for controlling said heater, said first power drive means, and said second power drive means.
- 6. The machine of claim 5 wherein said controller includes programming responsive to temperature sensed by said temperature sensor to control said heater so as to not boil said beer wort in said brew pot.
- 7. The machine of claim 5 wherein said turn table member includes plural ingredients containers and plural aperture-cover portions alternating with one another circumferentially of said turn table member, a respective one of said plural aperture-cover portions aligning with said aperture when said second pinion runs off a gear segment to stop said turn table member.
- 8. The machine of claim 5 wherein each of said plural ingredients containers and said housing defining cooperating means for dispensing ingredients from one of said ingredients containers as said turn table member rotates incrementally between stops to pass the one ingredients container over said aperture.
- 9. The machine of claim 8 wherein said cooperating means for dispensing ingredients from one of said ingredients containers includes said plural ingredients containers being circumferentially arrayed on said turn table member, and each container being configured as an ingredient cup pivotally supported on said turn table member, said housing carrying means for tipping the one of said ingredient cups passing over said aperture, and the turn table member having a funnel-like wall section disposed below each ingredient cup and disposed to deflect ingredients therefrom into said aperture.
- 10. The machine of claim 5 wherein said motor drives both of said power drive for a stirrer, and said incremental-movement power-drive ingredients dispenser; said cooperative drive means connecting the stirrer with the power-drive for a stirrer when said brew pot and cover are received into said recess including a drive gear drivingly connected with said motor, and a driven gear carried by said stirrer and meshing with said drive gear when said brew pot and cover are in said recess.
- 11. An brew pot with lid for use in automated home-brewing of beer, said brew pot with lid comprising:
- a brew pot portion having a bottom wall and a side wall, said walls cooperatively defining an upwardly opening cavity in the brew pot, and the side wall having a lip defining an opening to said cavity;
