Abstract
Some embodiments of an exemplary manual or electric grain mills may include a mill body; a mill mechanism disposed within the mill body, the mill mechanism including a mill shaft and a shaft coupling; a hand crank having a hand crank driveshaft configured to be selectively coupled to the shaft coupling to drive the mill mechanism when the hand crank is manually operated; and a motor assembly. The motor assembly may include a motor housing, a motor disposed within the motor housing, and a motor driveshaft operatively coupled to the motor, the motor driveshaft being configured to be selectively couple to the shaft coupling and drive the mill mechanism when the motor is powered.
Claims20
A grain mill comprising:
- a mill body;
- a mill mechanism disposed within the mill body, the mill mechanism including a mill shaft and a shaft coupling;
- a hand crank having a hand crank driveshaft configured to be selectively coupled to the shaft coupling to drive the mill mechanism when the hand crank is manually operated;
- and
- a motor assembly, the motor assembly having,
- a motor housing,
- a motor disposed within the motor housing,
- a motor driveshaft operatively coupled to the motor, the motor driveshaft being configured to be selectively coupled to the shaft coupling and drive the mill mechanism when the motor is powered,
- a support arm extending outwardly from the motor housing, the support arm being configured to prevent rotation of the motor assembly with respect to the mill body when the motor is powered, and
- a bend on the support arm, the bend configured to at least partially wrap around the mill body to prevent the motor assembly from being moved to withdraw the motor driveshaft from the shaft coupling.
A grain mill configured to be selectively driven by a motor or a hand crank, the mill comprising:
- a mill body comprising a mill shaft connected to a shaft coupling;
- a hand crank comprising a hand crank driveshaft configured to be selectively coupled to the shaft coupling to drive the mill shaft when the hand crank is manually rotated;
- a motor housing comprising a motor operatively coupled to a transmission, the transmission being operatively coupled to a driveshaft, the driveshaft being configured to be selectively coupled to the shaft coupling and drive the mill shaft when the motor is powered;
- and
- a support arm extending outwardly from the motor housing, the support arm comprising a bend at a distal end,
- wherein the support arm and bend are configured to rotationally engage with the mill body when the motor is powered to prevent rotation of the motor housing with respect to the mill body and to prevent the motor housing from being moved to withdraw the driveshaft from the shaft coupling.
A mill configured to be selectively driven by a motor or a hand crank, the mill comprising:
- a mill body comprising a shaft coupling;
- a hand crank configured to be selectively coupled to the shaft coupling to drive a mill mechanism when the hand crank is manually rotated;
- a motor housing comprising a motor operatively coupled to a driveshaft, the driveshaft being configured to be selectively coupled to the shaft coupling to drive the mill mechanism when the motor is powered;
- and
- a support arm extending outwardly from the motor housing, the support arm comprising a bend at a distal end,
- wherein the bend prevents the motor housing from being moved away from the mill body to withdraw the driveshaft from the shaft coupling when the motor is powered.
