#1-The red balls are part of the governor. If the balls swing out too far, the available steam will be cut back. This prevents the motor from running too fast.

#3-The round part with the red rings is the cylinder. Box to the right side contains the valves. Box on top with the red top is part of the oiler that lubricates the cylinder.

#4-Look at the main frame and the shaft. Just to the left is the eccentric part. The eccentric takes a turning motion & turns it into a back and forth motion. The silver rod is attached to the valves that feed steam to the cylinder.

If there is only one eccentric, the motor turns in one direction only. In the above image, the piston cylinder drives the shaft and is attached to the right side of the main block.#5 Below. Closer look at the eccentric part.

Really enjoy your pics & history. In #1 the term "balls to wall" originated from a steam engine running at top speed with the governor balls spinning just about straight out. Today: anything or person working fast.

Balls-to-the-wall is a fighter jet term. The throttle lever has a large ball on the top, which is pushed forward, against the instrument wall, for full thrust.
