Absolutely beautiful! And the simplicity makes a great demonstration of how these mechanical processes are really simple processors. This is boolean... every switch is on or off, 1 or 0. It's binary but, in series, conditions of and/or/not exist. But beyond my nerdery, it's just a beautiful piece of functioning history!
People don't believe me when I tell them that rotary dial dialing is digital. It's decimal pulse count modulation with a baud rate of 10. They used speeds closer to 18 for operator dialing sets. Pulse count dialing is perhaps the world's first mass scale digital addressing system.
@@td3993 Oh yes. And I'm old enough that there were cheap phones when I was a kid with buttons that pulse dialed. They always broke but stubborn me kept one after it broke and dialed it by clicking the hook the number of times for each number (0 is ten times of course.)
A fantastic feat of engineering with the floor selector array, this one is huge! From what I can see it's an earlier version of the well known pie plate floor selector, with the chain linkage in the hoist way. No arcing from the magnetic motor starter's contacts, when the circuit opened. Traction machine runs smooth. Preserve this elevator, it's engineering history.
Worked in the trade for over 50yrs but still know nothing. However that ‘selector’ (all those revolving contacts on the back) is one of the first automatic elevators. It’s kinda like a dinosaur bone found in a tarpit. The selector got its name by being a device that signals which direction run and where to stop. I have many pics and videos of old wooden 😊elevators that are still in service. It’s
That’s awesome. What company were you with and what local? Always love hearing from mechanics and former mechanics. And yeah, the lollipop selector is really neat. It’s always cool to see one still in action.
Never saw a 2SOB. 1SOB - single spd single call automatic. With 2spd came new selector and the 2:40 operation changed to collective automatic then fully selective collective automatic.
We have an Otis 1SOB (passenger controlled)) elevator installed in 1926 serving 5 levels. It is located in the Jerome Grand Hotel and is still in daily operation averaging approx. 100 trips per day. The equipment room is in the basement making it easy to maintain. Amazing how reliable it is.
I'd travel from the UK all the way over to where you are to film something like that! So cool and so rare!! What type of building was this installed in?
I have an extensive collection of 19th century elevators that are still in service. Maple rails, oak slings & flat leather belts. Would be delighted to share them. How does this old man do that? (Grandson don’t live close by)
Otis made a very similar horizontal selector for their 1SOB - meaning single button automatic. They musta sold millions of the 1SOBs their pie plates. Didja know the first Otis ‘pie plates’ were cast iron and were not conductors?
Nice machine last long long time. But elevator with computer short of life. All computers wash machines or dryer or oven or stove or vehicles much more are short of life.
Nice machine room . Recently retired Local 5 with 43 years . I worked on a lot of old equipment in the Philadelphia area.

Even the motor is 1 speed

The so called “pie plate selector”, the Otis 6850, isn’t driven by a chain in the hoistway. It’s driven by a toothed steel tape.
@@caroleast9636 ah yes my bad, I recall seeing the toothed steel tape in another video.
from the selector, it looks like it's a 15 stop installation. That brake is also a Hollister & Whitney add on.
Yup, 15 floors!

When things were made to literally last 100 years.
One of the coolest machine rooms on your channel so far

0:16 I would like to have a high-quality pic of this for a big poster .-)
Still purring great
increíble maquina ! que ingenio de Otis para diseñar algo así
Now that's what I call a "Real Machine"

I can smell the carbon (dust and old school lube and hot 3 phase dash pot oil and belt drive treatment cream no joke you'd never forget it 😊😊

mrmattandmrchay this is in an apartment building!! And yes, it’s such an interesting system!!!!

How does this old man do that? (Grandson don’t live close by)
That’s awesome! Do you have email? You could send it to me there

I’d reckon the 2SOB’s are the two button automatics then? And I don’t think I did!
This is TRUE Sequenｔial Controller, like the Music-box.
It’s pretty cool! There’s still a good amount scattered about chicago. This is one of the best examples though

هاذه تحفة هندسية. احسن من لوحة الموناليزا . ❤👍💪
Takiminie selector. Japanese designed from what I heard.
Interesting, where’d you hear that?
Woow❤❤❤
Wow.
