U.S. 964886: DEVICE FOR TEACHING SWIMMING, 1910

“designed for the purpose of teaching one the strokes and movements necessary for one to swim with ease … to be used on land and not in the water by which one acquires a habit of not only making the right strokes but also of making the right combination of strokes.”

The would-be swimmer lays on a base—his face sticking through, as though he were on a spa’s massage table—and cables are attached to his wrists and ankles. The right wrist cable passes over pulleys to the left ankle, and vice versa.
