    摘要： An improved disk harrow C-spring with a tapered cross section which reduces the compressive stresses in the inside radius and improves vertical and side-to-side flexibility. The curved portion of the C-spring has a constant cross section at the top and around three-fourths of the bend. At a location on the bend 45 degrees down from the horizontal, the thickness tapers to a location forward of the bearing hanger. The cross section is constant from the end of the taper to the end of the spring. The tapered cross section allows a thicker section to be used on the most highly stressed areas in the upper quadrant of the curved portion of the C-spring. The lower quadrant taper results in uniform stress distribution along the entire C-spring with the maximum compressive stress on the inside radius reduced substantially over a conventional C-spring. In addition, the tapered design provides an increase in both vertical and side-to-side flexibility for improved operation in rocky soil.

    摘要翻译： 一种改进的圆盘耙C型弹簧，具有锥形横截面，可减小内径的压缩应力，并提高垂直和侧对侧的灵活性。 C弹簧的弯曲部分在顶部和弯曲部的四分之三处具有恒定的横截面。 在弯曲处的水平位置下降45度的位置，厚度逐渐变细到轴承架的前方位置。 横截面从锥形的端部到弹簧的端部是恒定的。 锥形横截面允许在C弹簧的弯曲部分的上象限中的最高应力区域上使用较厚的部分。 下象限锥形导致沿着整个C形弹簧均匀的应力分布，内径半径上的最大压应力基本上大大降低了传统的C形弹簧。 此外，锥形设计提高了纵向和侧向的灵活性，以改善岩土的运行。

    摘要： A cotton harvester with an offset head having four row units positioned for harvesting cotton planted in uniformly spaced narrow rows. The frame of the harvester is supported near its forward end by a pair of drive wheels adapted to run between two pairs of rows of cotton. The head is offset so that three rows of cotton are accommodated between the wheels and one row of cotton is accommodated outside one of the wheels. The machine drive and guide wheels can therefore be positioned between the rows for ease in steering and driving. A cotton basket on the harvester can be dumped toward the side which is unobstructed by a harvesting unit so the receiving implement can be positioned closer to the harvester and so the head which is offset in the opposite direction can act as a counterweight to balance the harvester as the basket is extended transversely for dumping.
