I received these photos today from a reader who needs some help identifying these pivots. Which made me wonder…how do you typically go about replacing old pivots? They seem to be less standardized in size than other hardware products, but replacing like-for-like is critical because of the preps. How do you find the correct ones? Are replacements for old pivots readily available?
Any thoughts on the manufacturer/model of the pivots pictured below? WWYD?

On the frame portion of the top pivot, there is a number stamped in, maybe this can help.
The hole pattern of the top pivot looks to me like a Rixson 117 but the floor portion looks different.
Rixson, Dorma, IDC, aluminum door manufactures once you do a few it is a lot easer.. i find it better then retro fitting to something like a continuous hinge.
Whatever you do, DO NOT remove them until you have replacements. I had a service tech who thought the best way to figure out what the pivots were was to take the door down, remove the pivots and try to find ones that matched. Unfortunately, the bottom pivot fell to pieces when it was removed and could no longer be put back on the door. The X-ray room was out-of-service for several days since the door could not be rehung with the broken pivot. We had to replace the door and the pivots (and rework the frame) since we couldn’t find a pivot that fit. It was a nightmare!
Looks like the Ives 7222 Pivot set.
The base plate for the bottom pivot looks like the Ives 7222 in the catalog.
easy one
it s called a roton hinge
I am guessing that is a 1940-60 version of today’s Rixson 147 pivot but I don’t have a catalog that old to go back to. Obviously the bottom escutheon has had a “local” modification.
rixon or dorma usually have a replacement to fit.
I always recommend a continuous hinge to replace broken pivots!
Like most hardware geeks would, design, shape, size, screw pattern. Using a template will help details. Leaning to the Ives 7222 also. Looks like it has some years on it. I would what to find some old GJ data.
I just want to thank Lori and all you guys for helping. It was stamped LCN and now Ives makes it. Bill P you are correct it was the Ives 7222!
Top is an old LCN with set screw that only lets the pin rotate in the bushed frame portion and keeps pin from falling out.
Bottom matches.
Good detective work to all of you Part of being a Locksmith and door hardware technician is being a forensic specialist. . Years of practice and patience.
I’m with Adam. I always advise a Continuous Hinge to replace broken pivots.
If you blow up the image, it looks like it is stamped as “LCN”. I think they used to make pivots years ago.
