Abstract: A standing tree branch compression ring is adapted to be vertically raised about the trunk of the tree by lifting means. As the ring is lifted, the ring forcibly moves the tree branches inward. A plastic ring liner is affixed to the outer surface of the ring to reduce the coefficient of friction of the ring to mitigate tree branch damage. The ring includes a plurality of segments that form a generally toroidal shape and includes a releasable segment to accept the tree trunk from the side. The segment is then connected to the remainder of the ring, around the tree trunk, before the ring is raised.

Abstract: A jaw and a related jaw assembly, the jaw assembly having a master jaw with a longitudinal axis and top and bottom surfaces, first and second side surfaces, a master jaw bore extending longitudinally therein between the top and bottom surfaces, and a channel extending from the first side surface to the second side surface generally transverse the longitudinal axis, and a top jaw adapted to be coupled to the master jaw and defining a top jaw bore positioned in substantial alignment with the master jaw bore.

Abstract: A self-standing mobile device for cutting sheet material including a body member connected to at least one wheeled axle to translationally move the body member about a surface on which the device self-stands. The body member includes a cutting notch with open and closed ends, the cutting notch positioned with the open end above the at least one wheeled axle. The body member including a contained cutting blade member with cutting edge exposed within the cutting notch closed end, the cutting blade member oriented substantially perpendicularly to the surface on which the device self-stands. A user may engage the device to move the device about the surface on the at least one wheeled axle to cut a sheet of material passing into the cutting notch. Handle and shoulder features, and related methods of cutting sheet material are also disclosed.
