Mobile grain auger

Claim 2

A mobile grain auger comprising an elongated cylindrical casing having an intake end and a discharge end, a helicoidal auger flight extending through the casing, a motor to rotate the flight to convey grain from the intake end to the discharge end of the casing, two legs defining a calliper frame and having their divergent ends extending upwardly and supporting the casing at spaced positions along its length, a pair of coaxial ground wheels supporting a horizontal pivotal axis about which the frame is tiltable in a vertical plane, first adjustment means formed by a first winch and cable operable to change the calliper angle, a lever including vertically and horizontally extending limbs fulcrummed to said horizontal pivotal axis and a reaction member on said horizontally extending limb positioned to engage the ground between the common axis of the wheels and the intake end of the casing, said vertically extending limb being disposed between said legs of said calliper frame, and tilt adjustment means formed by a second winch and cable connected between the calliper frame and the lever and operable to vary the slope of the casing in a a controlled manner.

Claim 3

An auger as claimed in claim 1, in which said second winch and cable is further operable to displace the lever between an operating position at which the reaction member engages the ground, and a stowage position at which the reaction member is held clear of the ground.

Claim 4

An auger as claimed in claim 2, in which the lever is a bell-crank lever having said vertically extending limb to which the second adjustment means are attached, and said horizontally extending limb carrying the reaction member at its end.

Claim 5

A mobile elevator comprising an elongated structure supporting a belt loop having an intake end and a discharge end, a motor to drive the upper run of the belt from the intake end to the discharge end, two legs defining a calliper frame lying in the vertical plane and having their divergent upper ends extending upwardly and supporting the structure at spaced positions along its length, a pair of coaxial ground wheels supporting a horizontal pivotal axis about which the frame is tiltable in a vertical plane, first adjustment means formed by a first winch and cable and operable to change the calliper angle, a lever including vertically and horizontally extending limbs fulcrummed to said horizontal pivotal axis and a reaction member on said horizontally extending limb positioned to engage the ground between the common axis of the wheels and the heavier intake end of the elongated structure, said vertically extending limb being disposed between said legs of said calliper frame, and tilt adjustment means formed by a second winch and cable and connected between the calliper frame and the lever and operable to vary the slope of the structure and, thus, the belt in a controlled manner.

Claim 6

A mobile elevator comprising an elongated structure supporting a belt loop having an intake end and a discharge end, a motor to drive the upper run of the belt from the intake end to the discharge end, two legs defining a calliper frame lying in the vertical plane and having their divergent upper ends extending upwardly and supporting the structure at spaced positions along its length, a pair of coaxial ground wheels supporting a horizontal pivotal axis about which the frame is tiltable in a vertical plane, first adjustment means formed by a first winch and cable and operable to change the calliper angle, a lever including vertically and horizontally extending limbs fulcrummed to said horizontal pivotal axis and a reaction member on said horizontally extending limb positioned to engage the ground between the common axis of the wheels and the heavier intake end of the elongated structure, said vertically extending limb being disposed between said legs of said calliper frame, and tilt adjustment means formed by a second winch and cable and connected between the calliper frame and the lever and operable to vary the slope of the structure and, thus, the belt in a controlled manner.

Claim 7

An elevator as claimed in claim 4, in which said second winch and cable is further operable to displace the lever between an operating position at which the reaction member engages the ground, and a stowage position at which the reaction member is held clear of the ground.
