Replacement parts for pat US3444648A

Question

Hi,

I have some multi-panel awning windows in need of repair- the part where the lever arm attaches to the rest of the driver is broken and I'm having trouble finding replacements- I can see it says patent number US3444648A if it's any help! Thank you

I've only seen that patent number once before, but it was unfortunately an uncertain outcome, according to our records. At this stage I cannot say for sure what you have in your window.

In order to proceed, I will need you to remove the operator from the window entirely and in one piece. I will then need clear photos of the part in question so that we can check our inventory for a match.

For reference, I need to see a clear shot of the hole pattern (all three holes in one photo) and a clear shot of the link arm.

Please let me know if that would be possible and we can work from there.
