the leg to generate the required power.

[Illustration: GOODES' IMPROVED TREADLE MOTION.]

A pendulum, A, is pivoted to the underside of the table and carries a
heavy disk, B. To the central pivot of B is attached a foot piece, C.
The bottom of B is slotted, and through the slot passes a stationary
rod, D, which holds the bottom of the disk from vibrating while it
causes the upper part to reciprocate with the swinging of A.

To the upper part of B is pivoted a pitman which actuates the crank as
shown.

In operation the foot is placed upon the foot piece, and a swinging
motion is imparted by it to the pendulum, which is ultimately converted
into rotary motion by the crank as described. The heavy disk, B, gives
steadiness to the motion, and acts in concert with the fly wheel on the
crank shaft for this purpose; but it is not essential that this part of
the device should be a disk; any equivalent may be substituted for the
same purpose.
