The Shadowgraph! ...or: Walt the Inventor
This was all new to me, or so I thought at first. Slowly it dawned on me: back in the late 70s, I had an opportunity to search out some patents, and I looked for the name Walt Disney. I received a document that left me puzzled, because it didn't make much sense to me. Now, with the above document in mind, it is all coming together! I looked it up on the internet, and yes, there it was again, the same thing! The only patent attributed solely to Walt Disney himself - it is the Shadowgraph!
For easy viewing, here is the patent document as JPGs:
Hands up everyone who has heard of this contraption before!
Now to find some examples... Here are a few:

Of course, there is practically no way of knowing if this was actually invented by Walt himself. On the other hand, it seems that the actual inventors have been allowed by Walt to claim their own inventions on other occasions (unless they had left the studio), as the inventions were assigned to Walt Disney Productions anyway.
Other interesting early Disney patents include the bouncing ball as means of sound synchronization (attributed to Roy O. Disney(!), a month before the premiere of Steamboat Willie), the universally used Click Track (attributed to studio engineer Bill Garity a few months after Ub Iwerks had left the studio), the Bar Sheet (by Walt, Wilfred Jaxon and Bill Garity), a beat generating machine by Garity, and the vertical Multiplane Camera by Garity, a very elaborate patent!
[Addition: in all my years in the animation business, I have never run across anyone using this device. Now, of course, the same effect could be created using a computer simulation. Using the painted drawings, one could map them in a CG program onto a shape. Has anyone done this? I don't know, but I wouldn't be surprised...]
