Abstract: The Tummy Twister is essentially a long metal tube with a protracted “S” shape. Near the bottom is a small bend that curves away from the user; near the top is a larger longer bend that curves toward the user. At the top is a pair of handle grips that extend out perpendicularly from the tube. Tummy Twister comes with a plastic water weight container which will hold 7 lbs. of water. While the user stands erect, holding on to the hand grips and twists his upper torso, the weight provides resistance and the angle of the curves in the tube concentrates the effect, thereby strengthening abs and oblique-in other words the stomach and waistline.

Abstract: Apparatus for suspending a flexible banner with respect to an upstanding post and including a pair of base plates that are fixed in spaced relation on the post, the base plates each having a pair of grooves extending longitudinally of the post adjacent the side edges of the base plate and a pair of swing plates having a pair of longitudinally extending lips that rest normally in the pairs of grooves in the base plates and each having means for fixing a banner supporting rod in the swing plate whereby the swing plates and the rods may be pivoted with respect to the base plate, and a spring between each of the swing plates and its respective base plate for yieldably restraining swinging movement of the swing plate and its rod.

Abstract: An athletic exerciser comprising a fixed support post having a support pipe telescoped in and rotatable in the support post and supporting a pair of exercise swing arms from its upper end. The swing arms have downwardly depending arm portions connected at their ends by handlebars. A bench is supported at its rear end with respect to the support post by means of a vertical pivot rod extending into a corresponding tube portion carried by the post so that the bench can be swung sidewardly or can be removed completely from the post by lifting the pivot rod out of the tube portion.

Abstract: An athletic exercising device comprising a handle mounted on swing arms pivotally mounted on a support tube that is vertically moveable on an upstanding standpipe and a spring loaded set pin for adjustably fixing the support tube in desired vertical positions on the standpipe. A piston-cylinder assembly is carried by the tube, and a closed hydraulic circuit is connected to the two ends of the cylinder. A piston rod is connected to the piston of the assembly and to the swing arms so that the arms and handle can be moved for exercising purposes against the action of the fluid acted on by the piston. The tube allows the assembly to be inverted on the standpipe and also to be rotated on the standpipe through 180 degrees for different exercises.

Abstract: Equipment for exercising the muscles of a user includes a horizontally extending main frame and bench, an elevator leg supporting an elevator carriage for vertical movement with respect thereto situated at one end of the bench, an endless chain extending from the top to the bottom of the elevator leg and means to attach the elevator carriage to the main chain at appropriate heights. Actuating arms can be temporarily fixedly mounted to the elevator carriage so that a user can make repetitive movement in upward or downward direction on those arms. A chain sprocket driven by the endless drive chain drives a pinion which drives a rack/piston rod forming part of a piston/cylinder positive displacement linear pump. A path is provided between the opposite ends of the pump, and means is provided in the path to restrict the flow of fluid thus to provide resistance to repetitive movements of the user on the actuating arms in one direction.
