Abstract
A torsion spring adjustment assembly for supporting a finger wheel rake that includes a lever operably connected to a torsion spring supporting the finger wheel rake for setting the tension of the torsion spring. The lever is pivotable about the axis of a rotational shaft of the finger wheel rake to a plurality of tension-setting positions and is secured to a main frame of the finger wheel rake at a position selected from the plurality of tension-setting positions. The lever is adjusted to a select position and then secured against the adjustment plate by a mechanical fastener.
Claims21
A torsion spring adjustment assembly for supporting a rake arm and finger wheel on a main frame of a finger wheel rake, the torsion spring assembly comprising:
- a lever operably connected to a torsion spring configured to support the rake arm for setting a tension of the torsion spring, the lever being pivotable about an axis of rotation of a rotational shaft of the finger wheel to a plurality of tension-setting positions and configured to be secured to the main frame of the finger wheel rake at a position selected from the plurality of tension-setting positions, the lever configured to be secured to the main frame using a mechanical fastener, and the lever comprising a mounting socket through which the lever is configured to be secured to the main frame;
- and
- an adjustment plate configured to be attached to the main frame, the adjustment plate determining the plurality of tension-setting positions, wherein the adjustment plate extends downwardly from the main frame in use, the adjustment plate comprising a female connector through which the lever is configured to be secured to the main frame, the adjustment plate defining a posterior space occupied by the finger wheel and an anterior space occupied by the lever and torsion spring in use, the female connector extending between the anterior space and posterior space.
