“The Shakers: America’s Quiet Revolutionaries” is a fantastic temporary exhibition at the New York State Museum, located in Albany, New York. In addition to shaker artifacts, there are a number of gorgeous WPA-era photographs of shaker communities. Another part of the exhibition focuses on inventions, which include a flat broom, washing machine, water turbine, folding steroscope, swivel foot for chair legs, and many others.
I particularly liked their very simple method to turn a press screw, pictured below. Usually this is one of the most complicated areas of a press. By simply offsetting the holes ninety degrees, a tommy bar (called a press pin in bookbinding) can be alternately inserted to complete full rotations from one side of the press. Genius! Also note the simple two part platen holder, which looks a little rinky-dink but apparently has functioned for many years.
