  • Patent number: 4904011
    Abstract: A shovel formed of a blade member, two side members, a handle retaining member, and a handle. In one embodiment, each of the blade member, two side members and handle retaining member is formed as a metal blank, which is stamped, punched and bent to the desired configuration, with the metal blanks of the sides and handle retaining member having formed therein interlocking coacting detenting elements for enabling adjustment of the angle of the handle relative to the blade portion. Welds and a rivet complete the assembly of the shovel. In an alternate embodiment, a single metal blank is used to form the blade and the two side members as a unit, thus avoiding welding or other fastening of the sides to the blade. A foot pressure rest is provided with the blade, with the side members generally parallel and spaced the width of the blade. The handle is attached at an angle which enables effective application of force during use.
