Mechanical Principles (1930) by Ralph Steiner [4min selection]

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
Several users have commented that these gears may be on display at The Museum of Science and Industry in Chicago, IL.

The thing people don't realise about the gear wars, is that it was never really about the gears at all.

[@supersonictumbleweed]

@@laurean5998 actually it's something used where perpendicular force driven by torque to the teeth would be too great. It's a way to increase the contact surface without making the gears triple it's width (depth)

[@laurean5998]

@@supersonictumbleweed Why would the contact surface be bigger than that of a normal straight cut gear with the same diameter and tooth width? Do you have a link? Im pretty sure there is 0 torque applied to the teeth of gears, only radial and tangential (and axial in helical gears) forces resulting in or out of a torque in the shaft. Do you mean this can somehow reduce the radial force? That just makes no sense, you'd have to change your teeth to do that.
