Description: "Atwood's Machine. This difficulty has however been overcome by a curious piece of machinery invented by Mr. Atwood. This consists of an upright pillar, with a wheel on the top. The weights A and B are of the same size and are made to balance each other, exactly, being connected by a thread passing over the wheel. The ring R admits the weight A, to fall through it in its passage to the stage S, on which it rests. The right and stage slide up and down, and are fastened by a thumb screw. The pillar is a graduated scale, and M is a small bent wire, weighing a quarter of an ounce, and longer than the diameter of the ring." —Comstock, 1850
