  • Patent number: 5085478
    Abstract: The cushioning step for the blade of a tool, according to the invention, has an elongated elastomeric member having an axially-extending, blade-engaging, generally L-shaped slot, oriented so that the step may be placed on the top edge of the blade of a tool wherein the blade is positioned in the slot. The slot is located intermediate the opposed side faces of the stop to define opposed saddle portions which rest on the opposed sides of the blade. A generally horizontally-extending portion of the L-shaped slot accommodates the blade-top construction of a forwardly-turned shovel. An inwardly-turned projection is located at the lower portion of the slot for providing a line contact with the front-surface of the blade. The step further includes a pair of axially-extending, clip-receiving openings located on opposite sides of the blade-engaging slot for receiving the legs of a bifurcated clip for securing the step to the blade.
