Mechanisms in action Ralph Steiner

This video is a section from Mechanical Principles by Ralph Steiner done in 1930.
Lots of funky motions and mechanisms here.
Could be useful for my Absinthium project.
Keep your sightglass full, your firebox trimmed and your water iced.

From the YouTube page:
This is my favorite 4min selection of a larger work by Ralph Steiner. The original was silent, and the DVD had it set to classical music. I have swapped the audio for an electronica/industrial track by 3 Liquid Hz - Little Boy.

Favorite movements:
@ 1:16 - counter mechanism
@ 2:55 - normal gears, but cut to engage on diagonals
@ 3:37 - SQUARE GEARS!
@ 3:41 - variable speed transfer
@ 3:46 - rotary to linear action with a 4 tooth cog
