Here is the link to the YouTube video of the test run for the dumbwaiter....Everything will now be disassembled for paint, finish, and polishing. Once done, it will be on display in the new area of the Museum, right by the shop. That is a 120 year old motor powering the unit. I'm figuring another 4-6 weeks of work on this project before all done. We're hoping the museum will be open again to visitors by Fall. https://youtu.be/JnTaIZ02tqo Last edited on Thu Feb 18th, 2021 02:42 pm by Kim Frank |

You think that the "waiter" is big enough that Jon Brown could get in it for a ride to the top ?

Don't know about that, but it's perfect for moving desk fans between floors.

It's doable, James, but to even out the weight,... Jon in one car, fans in the other. ![]() I'd pay to see that! ![]()

Very cool. I have to laugh, the first thing I thought of is the worlds oddest "oscillating" fan. One 16" fan in each going up and down, over and over spreading air through all levels of the room...

Unfortunately for Jon, the ride has a height requirement...No such requirement for the Dental chair though. Jon's about due for a checkup..... Attached Image (viewed 232 times):

That is an amazing piece of engineering by Tom; and its story of having been almost lost yet being returned to the friends of its original designer is great! The Crocker-Wheeler motor sounds like new in spite of being 120 years old. I know that is the result of quite a bit of work but it is none the less very impressive! I'll admit I have not read each and every post in this thread in its entirety so forgive me if you have already answered this. How do the limit switches work? It seems that the dumbwaiter carriages lock into the silver metal sockets with a nice decisive "click" and the motor stops at just the right moment. Very impressive!

As I understand it, when one carriage contacts the switch it closes one circuit and opens another at the other switch. This in turn goes thru a relay and reverses polarity to the motor. The momentary switch starts the motor enough to raise the carriage off the switch, which then powers up and raises the carriage and brings the other one down....back and forth, back and forth. I think this is how it works. I just make 'em pretty. Here is the finished motor...... Attached Image (viewed 149 times): Last edited on Mon Feb 22nd, 2021 12:56 pm by Kim Frank |

And the inside of the switch. It has two positions...NO (normally open) and NC (normally closed)…. Attached Image (viewed 123 times):

At the top of the dumbwaiter, there will be a blade turning as the carriages rise and fall. Here is the machined hub.... Attached Image (viewed 56 times):
