    m guessing that there is some type of cam that raises the bar to release the string. Anyone seen this before or have any information on this lock?

    Possibly a leaf spring assisted “clap lock” pretty elegant method.

    Nice looking crossbow and interesting release.

    Agree with septua. Spring action string lift. Trigger sear probably latches into a hole in the tang when cocked

    Looks like a fancy and elegant version of a pin-lock almost -- lifting the string up to the level of the bolt.

    The big difference betwee the pin lock and the clap lock is that in the case of the latter the string does the lifting

    I disagree slightly.  The pin lock uses a hard notch to retain the string.  The pin pushes the string out of the notch, over a fairly hard/sharp corner.  The claplock retains the string with a 'hand', which levers the string up, so it may run up a slope to strike the bolt.  Both types slap the bolt, but the claplock should be easier on string serving and possibly bolt-butts as well.  Grump... I still like the roller-lock better, but think the claplock offers more possibilities for sophisticated release than a pin lock.  The pin lock's great virtue is simplicity.  Geezer.

    Both the clap and pin lock experience some energy loss from the string slamming into the bolt correct? I know that the roller nut experiences little to no energy loss because the butt of the bolt always maintains contact with the string.

    Well the string Does have to roll the nut over for release, which will cost some energy, depending on how heavy the nut is.  That's one of the problems with metal (particularly brass) nuts.  They eat energy and increase lock-time.  There's always something.  Geezer

    I have seen a Filipino crossbow I doubt the trigger mechanism it uses, wastes any energy. The fingers that hold the string are two metal pins attached to the trigger. When you pull on the trigger the pins go down. So unlike a roller nut which the string has to push the nut to move which I can see could waste some energy. All the string has to do is go forward once the pins lower down.

    Yes, I've seen releases with paired drop-pins.  The old Jayhawk kits, sold in the 60s ued those.  I think you would run into problems with string wear and excessive trigger-drag, but there should be no noticeable energy loss to the lock.  (I've even seen a few medieval bows that worked that way.... apparently toy bow, but even so...

    Thanks guys for the input. I found this crossbow while doing research for an upcoming project. I surely would like to examine this bow in person.
