  • Patent number: 6237974
    Abstract: A tool for moving debris within an elongate gutter having a lower surface and an upright surface. The tool includes an elongate member having a major portion which is substantially straight and an end portion with a substantially straight first edge at an acute angular relationship to a substantially straight second edge. The orientation of the end portion with respect to the elongate member is such that the first edge is in face-to-face abutment with the upright surface and the second edge is in face-to-face abutment with the lower surface, when the major portion of the elongate member is in a substantially parallel orientation with the gutter.

  • Patent number: 5189761
    Abstract: A flexible elongate strap for collecting and transporting recyclable milk containers includes opposite ends which can be fastened together, with one of the ends containing an opening, and the medial section of the strap defining a slot. A first milk container is attached to the strap by passing a first end of the strap through the handle of the container and then through the slot to form a loop around the handle. The end of the strap is then passed through the handles of additional containers which are retained on the strap by the first container. The hole in the end of the strap allows the strap and its attached containers to be suspended from a hook for storage. Prior to transporation the ends of the strap are fastened together to secure the containers to the strap.

  • Patent number: 4640540
    Abstract: The tool of the present invention is comprised of a scoop having flexible side walls which, at the mouth of the scoop, normally are wider and higher than the gutter into which the tool is to be inserted. The side walls become progressively narrower extending away from the mouth of the scoop and terminate in a heel at the closed end of the scoop which is considerably narrower than its mouth. In addition, the heel is relatively inflexible thereby allowing it to be inserted into a gutter which is much smaller than the remainder of the scoop. Once the heel is in place the remainder of the scoop can be inserted into the gutter by rotating the scoop downwardly while drawing the tool backwardly along the length of the gutter. Once in place the flexible side walls will conform to the shape of the gutter thereby completely filling the gutter. After the tool is inserted the gutter is cleaned by sliding the tool along the gutter until it is full.
