  • Patent number: 4291425
    Abstract: A cross or X-type socket wrench comprises a longitudinally extending shaft with socket wrenches at opposite ends thereof and a pair of shafts extending laterally from the central portion thereof. The laterally extending shafts extend at an obtuse angle to each other in a plane extending at a right angle to the longitudinal axis of the socket shaft and having pedal steps at the outer ends thereof. In the preferred embodiment the outer ends of the laterally extending shafts are rebent in a direction opposite to the obtuse angle of the shafts so that the weight of the rebent ends and the pedal steps supported thereon are located to maintain the center of gravity thereof on a line extending through the longitudinal axis of the socket shaft. The end of one of the pedal steps is sharpened and bent to provide a claw for removal of automobile hubcaps. In an alternate embodiment, the socket wrenches are removably supported on the ends of the socket shaft.
