You know what most excites me about this crossbow? That thanks to Peter Jackson's Lord Of The Rings Trilogy, it is now a movie star. This is the exact same type of crossbow that the Uruk-Hai use in Two Towers at the Battle Of Helm's Deep.
I suspect most people weren't watching to take notes of crossbow designs or excitedly saying "good lord, that's... that's from the Codex Löffelholz!" but who knows, maybe it'll get its own series in a few years
this looks extremely similar to da vinci rapid crossbow. Probably many people back then thought of the same prinsiples, "how should we makes crossbow reload faster"?. But AFAIK only Latchet crossbow used by border reiver is the only historical integrated mechanism crossbow that was ever used.
It is basically that very crossbow You can find a video where the "real" thing (the model built by the Leonardo3 center) is being used and the difference is pretty much trigger proportions and colour
Crossbow and bow draw weights are not directly comparable, though. The shorter draw length of the crossbow gives it less distance to accelerate the projectile. Therefore you need much higher draw weights to achieve the same velocity. Kind of like a pistol has a much shorter barrel than a rifle and thus much lower velocity even with the same ammunition. Even then the draw weight is not the only determinator of acceleration. Different materials when bent spring back to their original form at different speeds. A composite crossbow will likely accelerate the projectile more than a steel crossbow with the same draw weight and draw length. But steel crossbows could be mass produced more easily because composite crossbows are extremely labour intensive to make, althogh the materials were cheap compared to steel.
German codex Löffelholz crossbow is different from the Da vinci version, despite both being similar. Each group of peoples in Europe developed their own technologies separate from one another. German technology is so depurated, functional and accurate that it deserves a lot of respect. Germany is for sure the dominant power of Europe, but germans need to recognize the power they have comes in part by the developing of good relationships and collaboration with their excellent neighbours who surround them (Swiss, Austrians, Czechs, nordics, etc). By the way who can really assure that Da Vinci was the real developer of the crossbow with easy lever integrated mechanism?
The rough blue print for the crossbow from the Codex Loffelholz is found at the Jagiellonian Library in Krakow, Poland. But the PDF can be found online on their website (page 17 & 27/82): jbc.bj.uj.edu.pl/dlibra/doccontent?id=258834 The blueprints for another similar crossbow, Da Vinci's Balestra Veloce, in the Codex Atlanticus is found on that codex on pages 143, 153, & 155 / 1119. The Codex can be found online hosted by "The Visual Agency" media group: codex-atlanticus.it/#/Overview The only thing not too detailed is the internal mechanics. My suspicion is that it used the sliding plank (like from the Greek Gastraphetes crossbow) to hold an embedded rolling nut latch that was locked in place with a spring loaded sear. If so, the trigger would've been used to nudge the sear out of position to let the nut roll and release the string. A basic rolling nut and sear diagram could be found on the crossbow and sear (fire arm) pages on wikipedia.
I wonder, what is the speed and weight of the bolt shot from this crossbow. I'm looking for crossbow data, because there are really varying numbers concerning energy. For example, one guy gets barely 54J out of 450lbs crossbow, while a "Great Yew Crossbow" from your channel with only 386 lbs draw weight easily achieves 100J.
You have to take draw length into account as much as draw weight. The longer the draw, the greater the force behind the bolt because it has longer to accelerate. The "Great Yew Crossbow" seems to have a long draw length.
The mass of the bolt tip is a factor too. Joerg Sprave got 21.57 joules out from Ek Archery Cobra Deluxe 90 lbs pistol crossbow with 8 gram carbon fiber bolts and similar cocking mechanism/drawlenght. That has almost certainly higher lbs and the bolts are clearly almost three times heavier.
Ich habe noch nie so eine gute Handwerkskunst gesehen. Es lässt sich nicht in Worte fassen, wie schön diese Armbrust ist. Darf ich fragen, wie die Musik im Hintergrund heißt?
I think not faster than a regular crossbow with foot stirup ( 3 to 5 times per second) but the advantage is its draw weight (100kg) and its easy handling
Hallo, So eine Armbrust zu bauen währe eine tolle Herausforderung. Als erstes würde mich interessieren ob es einen Plan zu dieser Armbrust gibt. Außerdem, habe ich erfahren das man in Deutschland Stahlbögen kaufen kann. Leider habe ich noch nicht herausgefunden wo.
Ich habe die Skizzen aus dem Codex gut angeschaut und verstanden wie es funktioniert. Die Gesamtlänge des Baumes wurde mir sehr viel weiter helfen. Und den Bogen, kann man den irgendwo kaufen ???

Now I know where EK Archery got the idea for Cobra's and Adders. Having shot with the Cobra I can tell that the mechanism is still something revolutionary, even if it is 600 years old. Another thing, it's funny how fiction depicts the crossbows always to be silent. Owning two I can guarantee you that they are not, like the one in the video isn't either.
Well design and excellent job. As I know, these two designs are exactly near the same. What about the shooting ratio per minute compared with traditional crossbow?

A truly wunderful music in the backround. And also a marvelous crossbow. May i ask which piece was playing?

How could we achieve a longer draw length?
One possibility is to enlarge it to scale...

How fast can someone loose a bolt in a minute from this kind of crossbow compared with the regular one which has a foot stirrup?
