When was toggle lock action designed?

Toggle actions are a relatively exotic locking system that are relatively common and well-known because the system was used in a pair of particularly successful early guns: the Luger and Maxim/Vickers. There have also been toggle-action shotguns, military rifles, sporting rifles, and submachine guns, but the system went out of favor by the 1930s (except in the mind of one Adolf Furrer).

Most toggle-action designs use the toggle as a locked breech system, unlocked by a secondary operating system (usually short recoil). However, toggle system can also be the basis for delayed blowback actions, as in the Pedersen rifle.
