Abstract: A book alignment device engages a back side of objects that are misaligned on a plane and applies a transverse force against the back side of the objects to align the objects on the plane. The device aligns the separate, misaligned objects into a single aligned set of objects. In this manner, the objects are not only aligned, but compacted into a stronger, unitary configuration that forms a single set of objects. An alignment rod forms an elongated member having a substantially straight configuration and a pair of free ends. The alignment rod engages a back side of the objects to pull them forward into alignment. A pair of lateral bars extend from the free ends of the alignment rod. The lateral bars have a distal end that perpendicularly joins the free ends of the alignment rod, and a proximal end that enables manipulation of the alignment rod.

Abstract: A rotary tiller device provides at least one interchangeable torqueing apparatus to generate different torques and angular velocities for tilling soil and removing weeds with at least one interchangeable rotary shank. The type, size, and voltage of the torqueing apparatus is dictated by the type of soil and nature of the work being performed. The interchangeable rotary shank is also interchangeably attached based on the type of soil and tilling requirements. The device is lightweight and portable. The device includes a hollow shaft having a power end and a rotary end. The power end is adapted to interchangeably couple to the torqueing apparatus and includes a control portion for regulating the torqueing apparatus. The rotary end includes a rotary shank that rotatably engages the soil. A gear portion transmits torque from the torqueing apparatus to the rotary shank through a rotatable rod. A handle helps in controlling the device.
