Atwood's machine

The Atwood's machine is therefore forced on us; as to its construction, it is, as you are aware, composed of two upright posts, with a cross-bar fitted with pulleys and strings, and is intended to show the motion of bodies acting under a constant force—the force of gravity, to wit.

For the only "machines" possible to use in illustration of simple mechanics are the screw, the wedge, the scale, the lever, the wheel-and-axle, and Atwood's machine.

The earl therefore shot himself; and it was the small globular silver pistol, such as this'—here Zaleski drew a little embossed Venetian weapon from a drawer near him—'that appeared in the gloom to the excited Hester as a "ball of cotton," while it was being drawn upward by the Atwood's machine.

On the same page of my quires on which this is mentioned, there is a great list of apparatus to be constructed for Lucasian Lectures, notes of experiments with Atwood's Machine, &c.
