Maltby Handcuffs

This very rare example of the Maltby Handcuffs in functional shape with a key sold for $370 after 5 bids. 

These handcuffs have a very unique feature. The bow can be brought back all the way open, which activates the lever seen on the inside of the lock case. 

When the cuff is then pressed onto the wrist, the lever is pressed by the wrist and the swing arm is rapidly brought into place by the uncoiling spring. 

Above, the locking notches.

Below, a view into the interior of the clockwork-like lock mechanism. Note the coiled spring to the far right; this powers the self closing mechanism which is activated by the lever seen in the center.
