This invention relates to a mounting clip for a hay rake tooth and more particularly to an improved mounting clip that provides for more teeth and greater raking power.
Mounting clips are well-known in the art and include an elongated member with a center portion and two widened sections on each end. The central portion has legs or flanges that engage the sides of a wheel rim to prevent the clip from turning with respect to the rim of a wheel.
To provide sufficient strength to prevent turning during raking operations, conventional clips are 6.5 inches long. This length provides a spacing between teeth of 5.25 inches where a wheel having a diameter of 60.59 inches has 19 clips and 38 teeth. Under normal raking conditions, this design is acceptable. However, when used in short hay or shredded crops, an unacceptable amount of crop passes between the wider teeth and is left in the field. In heavy, wet crops, conventional rakes jump over the crop leaving hay because they lack sufficient raking power. Therefore a need exists in the art for a clip that addresses these deficiencies.
An objective of this invention is to provide a mounting clip that increases raking power.
A further objective of this invention is to provide a mounting clip that permits the mount of more teeth about a rim without reducing turning strength.
These and other objectives will be apparent to one of ordinary skill in the art based on the following written description, drawings and claims.
A mounting clip includes an elongated channel having a first end, a central portion, and an elongated second section. Along the elongated section are at least two laterally widened sections that provide greater surface area for receiving an elastomeric block of a tooth. At least one of the ends of the channel extend beyond one of the laterally widened sections.
Referring to the Figures, a mounting clip 10 includes an elongated channel 12 having a first end 14, a central portion 16, and a second end 18. The clip 10 is laterally widened in two or more sections 20 to provide greater surface contact area with a radially inner end of an elastomeric block 22. The central portion 16 of clip 10 is positioned between the widened sections 20 and at least one of ends 14 and 18 extend beyond the widened sections 20. Preferably, the length of the clip 10 is 6.0 inches with one end 14 having a length of 0.5 inches. In one embodiment the central section 16 extends the full length of the clip 10. In an alternative embodiment the clip 10 has multiple central portions 16 separated by a third, centrally located, widened section 20.
The mounting clip 10 has an opening 24 in the base 26 of the clip 10 and legs or flanges 28 that extend radially inwardly from the base 26 and around the sides of a hay rake wheel rim 30 to maintain the clip 10 in alignment with the rim 30. The flanges 28 preferably are longer in the central portion 16 and at ends 14 and 18 to prevent the clip 10 from turning with respect to the rim 30. The rim 30 also has an opening 32 that aligns with opening 24 to receive a fastener 34 therethrough to connect the clip 10 with rim 30.
A plurality of teeth assemblies 40 are connected to the mounting clip 10. Each tooth assembly 40 includes a tine 42 molded to one of the blocks 22. Preferably block 22 is made of an elastomeric material such as rubber or the like. The block 22 is adhered to the radial outer surface of the clip 10 at a first end 36 and an enlarged portion extends for substantially the entire width. Preferably the block 22 is of a symmetrical cross-section and reduces in size at a second end 38 away from the clip 10. A terminal end 44 of tine 42 extends outwardly from the shank 41 beyond block 22.
In operation, a plurality of mounting clips 10 are connected around the exterior of the wheel rim 30 by fasteners 34 received through the openings 24 in the mounting clip 10 and the openings 32 in the wheel rim. The length of the mounting clip 10 allows for a greater number of mounting clips 10 to be positioned about the wheel rim 30, thereby increasing the number of teeth assemblies 40. During raking the additional teeth assemblies 40 provide greater raking power. The flanges 28 of the clips 10 avoid strength reduction by preventing the clips 10 from turning and maintaining alignment of the clips 10 on the rim 30.
Therefore, a mounting clip has been disclosed that at the very least meets all the stated objectives.
This application claims the benefit of U.S. Provisional Application No. 61/812,813 filed Apr. 17, 2013.
