  • Patent number: 6732419
    Abstract: This invention discloses a method of inexpensively and reliably manufacturing a clip that has planar levers. A method for making a planar lever, which can be attached to the clamping element of a conventional binder clip, is described. Two wire members, which are bent near the end, and which each have a notched end, are inserted into a pre-formed planar member. The bend in the wire and the notched end hold the wires in place so that the lever can be attached to the clamping element. This invention also relates to a clip that has been manufactured according to the method of this invention. Finally, this invention discloses a method to make an advertising clip that can be used to hold the folded end of a collapsible tube, such as a tube of toothpaste, and a clip therefrom.

  • Patent number: 5039151
    Abstract: A snow shovel is disclosed which combines the straight transverse front or leading edge with the shape of a shallow scoop which forms a major part of the front face of the scoop of the shovel. The advantage is in that the shoveled snow tends to accumulate at the center of the scoop thus reducing the spill over the sides of the shovel and also facilitating the manipulation of the shovel filled with snow. The geometry of the handle is designed to facilitate the manipulation of the shovel.
