Hello,

While spending countless hours watching random Youtube videos I came across this video on how film projectors work and thought I'd share the link.
It's a fascinating piece of engineering.
Love it.

Can. Thats a great little youtube video. Thanks for sharing that one. While we all know how these work, this is great for showing people who do show a genuine interest in our hobby. My youngest Daughter is into retro things and is now collecting records. She also watched and followed what i did recently with my NT1 when i dismantled large parts to the best of my ability and she was fascinated when it all went back together and watched it working.
Iwas fasinated that it actually worked!!!
Great stuff.i see it has had a decent amount of viewings too.

Interesting video, indeed. There are many technical words I don't know in English but I could follow [Smile]

I have however a question : I thought what is called a "shuttle" in the video was a "claw". Is that two words for the same thing or am I mistaking ?

Have to say ive not heard the term shuttle before. Cant say id ever use that word.

Yes of course - shuttle is a quite legitimate description of the claw mechanism. It shuttles the film through the gate.

Thanks for your answers.

Terry, thanks for that, ive not heard it before but it makes sense. 40 years of collecting too [Embarrassed]

I just find it all fascinating and marvel at the engineering of such machines. How everything is synchronized and works to literally turn still frames into moving images with sound.
The way one element moves and then another does something else and then another pushes something etc etc.
Tom it must be very nice to be able to share your passion with your daughter. It just makes the hobby that extra bit fun.
It's a shame none of my friends are in to this kind of stuff but hey at least we have this forum:)

Bell & Howell used the term shuttle extensively since they had introduced the so-called shuttle film movement with the design 2709 standard camera back in 1911 (sold from summer 1912 on). The design 70 Filmo, 71 Eyemo, and the Filmo 8 cameras have a true shuttle, too. It oscillates stricly linearly down and up in the tradition of the Cinématographe Lumière.

Other terms used are pulldown and intermittent. I think claw is what is most commonly used.

I say reel, you say spool...lol!!!

I thought you called it a spool Rob! [Big Grin]

Quick crosswords often use the clue of Spool for the andser reel (and vice versa). :-)
