Abstract:
1. An apparatus for depositing particles carried in moving air currents, which comprises: a frame member; a generally horizontal axle mounted for rotation on said frame member; a plurality of blades secured to the horizontal axle for receiving and depositing such particles under the frame member and for rotatably moving with the axle caused by movement of the air currents and particles; a plurality of vertically displaceable supporting members attached to and depending from the frame member; lifting device associated with the frame member and each of the plurality of supporting members for vertically displacing each of the plurality of vertically displaceable supporting members; and power transmission means operatively associated with said horizontal axle and each of the lifting devices for transferring the energy of rotation of the horizontal axle to each said lifting devices for causing the vertically displacement of each of the plurality of vertically displaceable supporting members; whereby rotation of the horizontal axle by movement of the plurality of blades produces a periodic vertical displacement of each of the supporting members to lift the frame structure with respect to the deposited particles.
