Abstract
A livestock feed mixer includes a power source having a rotational power take-off. A mixer housing forms a mixing chamber for holding the feed ingredients and a rotatable mixing member is mounted within the mixing chamber. A variable speed power transfer mechanism is connected between the power take-off and the rotating mixing member for transferring power from the power source to the mixing member and for rotating the mixing member.
Claims18
Apparatus for mixing ingredients comprising:
- a power source having a rotational power take-off;
- a mixer housing forming a mixing chamber for holding said ingredients;
- at least one rotatable mixing member mounted within said mixing chamber for rotation about a mixing axis to cause mixing of said ingredients within said mixer housing;
- a variable power transfer device connected between said power take-off and said rotatable mixing member for transferring power from said power source to said rotatable mixing member for rotating said mixing member;
- said power transfer device being capable of automatically reducing or increasing the rotational speed of said mixing member in response to an increase or decrease, respectively in the power load said mixing member places on said power source.

Apparatus for mixing ingredients comprising:
- a power source having a rotational power takeoff;
- a mixer housing forming a mixing chamber for holding said ingredients;
- a rotatable mixing member mounted within said mixing chamber for rotation about a mixing axis to cause mixing of said ingredients within said mixer housing;
- an automatic transmission having an input end adapted to be rotatably driven at an input velocity and having an output end adapted to rotate at an output velocity in response to rotation of said input end, said transmission being adapted to automatically shift to change the ratio of said output velocity to said input velocity in response to changes in the rotational speed of said output velocity of said transmission output end;
- first drive connection means connecting said power take-off to said input end of said transmission;
- second drive connection means connecting said output end of said automatic transmission to said mixing member for rotating said mixing member.
