  • Patent number: 5056428
    Abstract: A device for compacting used tires has a rigid base member, a pair of columns rising from the base member, a top beam joining the uppermost extremities of the columns, and a movable engagement member adapted to slide upon the columns. A shaft vertically penetrates the top beam and is pivotally attached to the engagement member. In use, tires are stacked upon the base member, and the shaft, which is essentially a piston component emergent from a pressurized fluid chamber, is caused to force the engagement member downwardly. At the downwardmost point of travel of the engagement member, the tires are tied to form a bale. Retaining assemblies adjustably positioned upon the columns permit tires to be accumulated in multiple pressings prior to baling.

  • Patent number: 4848074
    Abstract: A rake-like device is provided for grasping and lifting a pile of fallen leaves. The device is comprised of a hollow handle having a rake head attached to its lowermost extremity. The rake head is provided with a circular array of a multitude of flexible metal tines. A cable is disposed within the handle and extends in a loop configuration to engagement with eyes associated with the tines. When the cable is pulled upwardly, the tines move radially in unison in an inwardly convergent manner. When the pulling force is removed, the tines return to their outwardly disposed positions.

  • Patent number: 4784513
    Abstract: An improved wedge is provided for securing the heads of striking tools such as hammers, axes and the like to the extremities of their elongated wooden handles. The wedge is of monolithic metal construction, having a downwardly directed edge or sufficient sharpness to penetrate wood, and having a centered aperture. When the wedge is driven into the handle, the wood grain expands into the aperture, thereby securing the wedge.
