Abstract: An exercise apparatus on which a wide variety of body exercises can be performed is disclosed herein having a base supporting an upright frame with a movable carriage traveling between guide tracks. The frame further supports an adjustable tension mechanism operably connected to the carriage for providing a resistance force against which the user applies muscle pressure. A handle is attached to the carriage and the carriage is movably mounted to the frame. Hand grips are coupled to the adjustable tension mechanism for use without the carriage and the base includes a first section supporting the frame and a second section for supporting the user or an incline bench. By orientation of the frame in a vertical or a horizontal position and by selected use of the carriage, various groups of muscle may be selectively exercised.

Abstract: A device is disclosed herein for releasably holding a nail so that it may be automatically driven into place by a hammer which includes a circular body portion or base having a central receptacle for insertably receiving the driving or impact head of the hammer. The base further includes an impact plate carried at the bottom of the receptacle having one surface formed to correspond to the striking surface of the hammer impact head and having its opposite surface formed with a curved recess for bearing against the head of a nail. The recess is coaxially disposed with respect to an opening in the base through which the nail extends. A stabilizing portion outwardly projects ahead of the base and includes a yoke for supporting the shank of the nail during the driving procedure.
