And no one has offered anything.

So, here is my 2 cents worth.

IMHO, there is 100% NO connection between the two cuffs aside from the fact that they are rigid and look somewhat the same in general configuration.

The German cuffs uses a completely different locking mechanism having a key that makes direct contact with a spindle that works on the ratchets and the American one uses the exact same lock as the Tower Double Lock handcuffs.

i.e. A lever mechanism with a double locking capability.

When one looks back at the German "Berliner" style cuffs you will see that the rigid body with arms that converge into a central lock case design has been something of a German staple and was obviously developed outside of any inspiration from the American design.

One would think that if the M.B. cuffs were inspired from the American patent we would see the same lever lock and single bitted key while instead the German design uses a double bitted key and no levers at all in the lock.

While they may look the same, I do not believe one was based on the other, etc.

Instead, different makers in different countries merely decided to make a rigid cuff that would confine the hands very close together.

I totally agree to Steve as I think these patents have absolutely nothing to do with each other. In addition, the Mühlenfeld No 113 belongs to the Berliner family according to the construction and design. The Berliner handcuffs have the following characteristics in common:

1. The bows are connected to a stirrup welded to the lock house.
2. When turning the key, both sides are released simultaneously by turning the spindle in the lock.
3. Most Berliner cuffs take a double bit barrel key, there are exceptions though.




The only known Berliner patent was filed in October 3, 1891, to Emanuel Pechnik , patent # 62419 by Kaiserliches Patentamt (German Emperial Patent Office). The patent drawing is pictured in an article by Michael Busch in the Handcuff Annual 2006.

Hi all for what its worth for many years I had in the collection a kahlke prototype made by mattatuck.
one of the wives to the mattatuck employees said that they were always testing out and making prototypes and that at one time she recalled being shown a wall full of one offs prototypes

I ended up the the kahlke model

It was unique obviously in its design. It was made as per the kahkle patent design and also incorporated the mattatuck "self cocking" bow system. You have to manually pull the bow to full open position to activate the lock inside.

this piece was made in brass with a dull nickle plating (i believe) over it and was very well made
here are some pics

Thanks for sharing these pictures Michael.

Did this Mattatuck // Kahlke prototype have a keyway on both sides?

Also, did it double lock like the standard Mattatuck handcuff?

Hi Lars
yes it has key on both sides
and it doesnt double lock, however due to its weight I also found it handy to hold papers down on my desk

Ha Ha, I think that most if not all Mattatucks have problems with their nickel plating peeling and falling off.

Very nice!
It had me fooled. I think this could quite possibly be your finest work (in my opinion)

Hi Mark, I have always been a great admirer of Ray McKee's work and his crafted handcuffs have been an inspiration to me. When I saw all the discussion on the Mattatuck kahkle, I was surprised that so many didn't seem to know the real origin of the cuff. Despite Mike Griffen and I talking about this cuff in 2005 and a few others cuffs he had made by Ray McKee, he seems to have forgotten it. I thought to myself, if the legendary Ray can do it, then maybe I can too.

cheers.

Ian
