Abstract
A rake is described which allows for adjustment between an ordinary lateral displacement working position and a medial delivery of materials. This is accomplished by providing a means whereby the main beam supporting the sets of raking wheels at each end is made into a two-piece beam which can be coupled into its standard rigid position or which can be pivoted forwardly relative to its direction of travel to change the angular disposition of the raking wheels relative to each other and thus change the delivery of materials from lateral to medial.
Claims7
A rake adapted for either lateral or medial displacement of material lying upon the ground, said rake having a predetermined direction of travel and including:
- A. a frame having a substantially rigid main beam and
- B. a plurality of rake wheels, each having ground engaging tines and being rotatably mounted toward each end of said main beam in operative relation with said frame, the planes of said wheels being generally parallel to each other and being angularly disposed so as to define an acute angle in relation to said direction of travel;
- C. the improvement for the variable adjustment of the planes of said wheels on each end of said beam from a parallel relation to an intersecting relation relative to each other for the medial displacement of material coming into engagement with said ground engaging tines, which comprises, in combination
- 1. first and second elongated beam members, in which at least one of said beam members is bent along its longitudinal axis,
- 2. coupling means for coupling said elongated beam members together in end to end relation in a first fixed position to form the rigid main beam,
- 3. pivot means associated with said coupling means for pivoting said main beam members relative to each other in a horizontal plane in the intended direction of travel of said rake to a second fixed position and to change the relationship of the planes of said rake wheels at one end of said beam from a parallel to intersecting relationship, relative to the planes of said rake wheels at the other end of said beam, and,
- 4. locking means for locking said beam sections in either said first or in said second position.
