#10Hi all.....now that some of you have received your 2007 Handcuff Annual, I'd be interested in your comments or thoughts on my theory about the possibility that Thomas Froggatt made the Mirror handcuffs (and perhaps a few other of his "specials)
I'd just like to know if you think I could be on the right track. Still a long way to go to prove it, but any help along the way would be appreciated.
Thanks
Hi Mick,
Yes, I know about the Plug leg irons.
I heard the same story myself about 20 years ago.
In regards to the Seance cuffs;...
I tend to agree with you.
Also, I think that the reason Houdini wanted something bigger and better is that for all intents and purposes the Seance cuffs look just like a slightly modified Irish 8.
The Mirror cuffs on the other hand are bigger, even more restrictive, and make more of a show.
Any other escapist could have modified an Irish 8 but the Mirrors were a singular design.
I also think that the so called "nested" Bramah cylinders is something of a red herring.
If one takes a good look at the key they will see lever cuts at the very tip, as common in all Bramah keys, and then there is this "thimble like" shoulder higher up with additional cuts.
I think the cuffs worked like this:
The cuts on the shoulder thimble were in fact meshed with a Bramah cylinder mounted near the keyway of the cuffs but this cylinder in and of itself did nothing to affect the locking or unlocking of the cuff.
This cylinder was pure deception and only would hamper the turning of an identical shaped key (and, as we all know, such blanks did not exists in Bramah locks but were exclusive to the Mirror cuffs alone).
The only way it impeded the turning of the key is if one had a key with correct tip cuts but incorrect shoulder cutts the key would not turn the back cylinder that actually unscrewed the bolt mount.
BUT...
That being said, any key with the correct tip cuts (and no odd thimble like shoulder or collar) could pass through the middle of and completely bypass the first Bramah cylinder.
I.E. The keypost was removed on the first and larger radial cylinder leaving only a hole in it's middle through which the longer and thinner shaft of the key with the tips cuts would pass.
So, Houdini had an original key and perhaps one minus the decieving "shoulder cuts" that would work directly on the back cylinder which was the only one locking the cuffs at all.
The second cylinder was only added so that the cuffs could be passed around to locksmiths of the day who would realize that at least with the existing keys, both sets of cuts for both cylinders would have to be correct for the key to turn and would thus sing high praises for the design.
As a locksmith and an escapist I have given this "nested Bramah lock" thing literally years of thought and it would HAVE to work this way for the key to be able to have any action on the back, or rear, cylinder.
Also, there is no probable way the cylinders could be mounted in a tubular lock housing like the body of the cuff where the key would work on both of them and both cylinders would have an independant security function in the locking of the bolt.
One cylinder locks the cuff, the other is window dressing that only provides the illusion of extra security where the unique shape of the Mirror cuff key is concerned.
I hope you get my drift here and I have not been too technical or jumbled.
Cheers, Steve Santini
