Hi, I'm the owner of the 2nd known Cosgrave/Codwell

[Model L]

What an amazing discovery! Can't wait to see the progress on this siren and eventually it running!

In June I will try and move it and begin the restoration.

This is an absolutely amazing find, thank you for bringing it to us. I'd be curious to see more pictures of the coding mechanism itself whenever that becomes an option.

Welcome to the forum! Thanks for posting this to the forum. Facebook, discord, reddit are great. But you can count on ARS being a good resource for archival information.

I do wish you the best on this restoration. If I recall correctly, you said the choppers are free and not seized up?

It will be neat to uncover the details of how this siren works as the teardown begins. Please keep this thread updated!

They are not moveable by hand however they are in good condition physically (Not pits or dings or even scratches just dirt and patina vs corrosion) is their status. My guess in the seize is that the motor is locked up, ice due to snow, or the screw thread is clogged. Once i get this thing vertical and I can work on it properly I can make a better assessment. If it is seized that still isn't the end of the world.

I'm doing a 100% complete teardown to every last bolt for this restoration so everything will be scrubbed clean and lubed and greased and etc so as long as it can be taken apart it can be fixed.

Oh for sure that will get detailed pictures. For now here is the patent that is my restoration guide (No service manual of course) https://patentimages.storage.googleapis ... 777283.pdf

Page 6/8 (On the pdf) and bottom left. It works akin to a starter gear advance/retract mechanism, rotation drives it up on a thread that moves the rotors up into position against the stators. When rotation slows it slides back down. This is all dampened by oil with a bypass mechanism like a hydraulic door slam reducer/etc.

Moving this might be easier its starting to become the talk of the station with a few people.

I don't want to clog the forums with a entirely seperate thread for this, does anyone know some good names I can contact to help with restoring this siren? I know my way around mechanical objects, have good knowledge of electric motors but I have never done a restoration this grand before. I want to get some advice with experienced people to prevent messing this up when the time comes.

I would would be more than happy to assist you with any questions you may have.
If you want any examples of my work, look at my Mobil Directo restoration.
There are also plenty of other highly experienced mechanics and technicians here that are happy to share knowledge and tips.
My suggestion would be to just field your general here on this thread, so any servicd knowledge we collectively gain on this exceptionally rare siren can be referred to in the future!

Jerry and myself would be happy to offer any tips and tricks we have aquired over the years, as I'm sure others will aswell. I might suggest joining the Siren Enthusiasts Facebook group, as there is some knowledge there that you won't find here, and vise versa, it is good to be connected to the community in as many ways as possible, especially when dealing with a rarity such as this.
