ABSTRACT:
A rake having a main rake and a supplemental rake thereon which is movable from a rest position to an open position where a load can be grasped to be deposited at a desired location. Both the main rake and the supplemental rake have tines with opposing points. When the supplemental rake is at a rest position, the above noted tines interleave with each other. The supplemental rake is hinged to the main rake and includes a pretensioned spring that is biased in such a manner so that the supplemental rake always tends to move into its rest position. When the supplemental rake is moved away from the main rake by an activation mechanism, the pretensioned spring is further tensioned and when a load is grasped between the two rakes the spring alone will keep the load there between without any further intervention by a worker. Additional mechanism has been provided which will extend the load capacity of the rake.
