The Schwarzlose machine gun was used by the Austro-Hungarian armies during WWI. To avoid Hiram Maxim’s multiple patents on machine gun mechanisms, the Schwarzlose uses a delayed-blowback mechanism. The breech is not locked to the barrel when the cartridge is fired, and so the breech and cartridge are blown to the rear as the bullet accelerates out of the barrel. To restrict the rearward movement of the breech until the bullet has exited to barrel, the Schwarzlose uses a series of levers arranged so that a small movement of the breech causes a much larger movement compressing the mainspring. The breech and levers are relatively heavy, so increasing the inertia to initial movement. However, as the cartridge has to start moving while there is still pressure in the barrel, a small amount of oil is squirted on each cartridge during loading.
The version shown in the animation uses the 8x50mm Mannlicher cartridge, and reaches a maximum of 480 rounds per minute.
Hi, I’m Rob, otherwise known as VBBSMYT.
I create the animations on my iMac using Cinema 4D, which I find very intuitive, and allows me to add smoke and flames, and then send the model to my trusty Render farm.
I make my models as accurate as possible through reference books and particularly good drawings. You may have seen my animations of early torpedoes and machine guns on YouTube. I enjoy finding out how things work and it has been fascinating to track the development from the late Victorian period up to World War 1.
