Abstract
A movable unloading auger is automatically latched and unlatched with respect to a support member by connecting a lifting winch and cable to a movable latch arm attached to the auger, thus advantageously permitting hands-off latching and unlatching operations. A guide member includes a slot and the latch arm extends through the slot and terminates adjacent a latch arm receiver.
Claims11
In combination with a container having a movable unloading auger, the improvement comprising:
- means for supporting said auger, said means being a support member connected to said container and extending therefrom;
- a latch arm movably mounted on said auger;
- a latch arm receiver connected to said container;
- means connected for raising and lowering said auger relative to said support, said means including a cable operably connected to move said latch arm between a first position, in engagement with said receiver, and a second position, out of engagement with said receiver;
- resilient means for urging said latch arm from said second position to said first position;
- means for guiding said latch arm and for limiting movement of said latch arm in said second position, said means being a guide plate having a latch arm receiving slot formed therein, said latch arm extending through said slot and terminating adjacent said receiver;
- said latch arm being moved from said first position to said second position when the tension in said cable overcomes the force of said resilient means;
- and
- said latch arm being moved from said second position to said first position when the force of said resilient means overcomes the tension in said cable.

An agricultural grinder-mixer comprising:
- an unloading auger movably connected to the mixer;
- support member connected to and extending from said mixer;
- a latch arm movably connected to said auger;
- means connected for raising and lowering said auger relative to said support, said means including a winch and cable operably connected to move said latch arm;
- a latch arm receiver connected to said mixer;
- means for guiding and limiting movement of said latch arm into and out of engagement with said receiver, said latch arm extended through a movement limiting slot in said guide means and further extended into a slot in said receiver;
- resilient means connected for urging said latch arm into a first position engaged with said receiver;
- means connected for moving said latch arm to a second position disengaged from said receiver in response to movement of said winch and cable, said means including an extension member and a pulley connected to said latch arm and to said cable;
- said latch arm being moved from said first position to said second position when the tension in said cable overcomes the force of said resilient means;
- and
- said latch arm being moved from said second position to said first position when the force of said resilient means overcomes the tension in said cable.
