  • Patent number: 4514970
    Abstract: A rake attachment for combining two conventional rakes to be used as a pick-up rake. The attachment provides two handle clamps, which may be substantially identical, each clamp to be attached to the free end of a rake handle. One rake handle is attached to its clamp to prevent rotational and longitudinal movement of the handle with respect to the clamp. The second handle is fastened to its clamp so as to allow rotation of the rake handle. The two clamps are then detachably and hingeably connected. The second rake may be rotated to bring its tines in opposition with the tines of the first rake, for use as a pick-up rake. Alternately, the second rake may be rotated so as to nest its tines with those of the first rake, allowing use of the apparatus as a conventional rake. Further, the clamps may be detached from one another, allowing each rake to be used for conventional raking.

  • Patent number: 4459905
    Abstract: A can crusher for axially crushing an empty can of the type having a recessed top and bottom and a pour hole in the top, the pour hole appearing when the tab is removed to empty the can. The present invention comprises first and second members having a hinge at one end for connecting the members in a hinged fashion. One of the members comprises a protrusion arranged for engaging the can bottom, preferably by protruding into the recessed bottom of the can. The other member comprises a pour hole protrusion for engaging the top of the can by protruding into the pour hole. The two protrusions are positioned on the respective members so that the can may be retained between the two members as the can is axially crushed by moving the unhinged ends of the members toward one another.
