Schwarzlose machine gun 1912

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.

To everyone who asks me to do an animation of their favourite gun. Four points: (1). I need a good set of drawings - engineering drawings showing the mechanism and internals, both plan and elevation. User manuals (any language) are also needed. If you want an animation, send me the drawings or a link. Then perhaps... (2) I need to be able to examine, and preferably dismantle, an example gun since drawings do not show everything. There are few places in the UK where this is possible (but I have my contacts). (3) I am really only interested in mechanisms up to the end of WW1 (say up to 1919). After that they often become too complicated. (4) I have a long list of guns I would like to model, and am only one person. If someone is prepared to offer money, then that request could go to the top of the priority list. Thank you for watching. Rob

Giulius' Mind Quite a few machineguns that did not have a fully locking mechanism or had violent extractions have had oilers. Some don't work right otherwhise, others even rip cases apart. The CETME/G3 had a similar problem that was solved with gas blowby instead. This problem has since been mostly been designed away.

[@フデフレ]

@@blecao After some research (as I have forgotten that I wrote this comment), no. The reasoning is that the original Austrian design had been altered to a quite extent by the Hotchkiss company's engineers by the time it got produced as the Hotchkiss series of machine guns (if I have read it correctly, and not the older "American" guns), leaving the gas piston the only part of the gun still Austrian. That is different from this gun which has some slight improvements from the original m/1907 machine gun bought by the Austro-Hungarian army from Mr Schwarzlose. At the same time, I do believe that I was naïve with the comment I left as with the same logic, all maxim pattern guns would be American/British, and Ksp 58 machine gun would be Belgian.

[@gaborv.6502]

1912M.s were used during WW2 too. It was a very reliable weapon and it could provide loooooooong continuous support fore for the infantry. Germans used every single one they could gather from Czech and Austrian stores. They were operated in "regiments with Czech weapons" (Infanterieregiments mit tschechischem Gerät). Most of them were lost during 1941-42, but the remaining units served as late as D-Day (schwarzloses of Atlantik Wall) in the western front and until the end of the war on eastern front and in the balkans. During ww2 Hungarian army every inf. battalion had one HMG company with 12 Schwarzlose (in addition, there were a couple of AT weapons and mortars). Each gun were carried by 3 horse/mule (1st: gun and tripod; 2nd & 3rd: ammo). It was operated by a whole squad: commander, 6 gunner-ammo handlers, 3 horseleaders. This quite big crew make 1912Ms quite mobile, and they could carry lots of ammo. Schwarzloses were also used as light AA MG in transport battalions of corps and in Divisional Supply and Support Service regiments. Each of them had 1 AAMG company with 12 Schwarclose on AA mount (there were dual and quad mounts, but most of Sch. were used on single mount on a truck or horse-drawn cart). Moreover the were used on armoured trains and armoured river patrol boats ("Őrnaszád") as DP guns (AA and anti-personel). It was a proven and durable weapon, but the water cooling had some issues, like the Russian winter (-30°C) in eastern front.

[@51WCDodge]

Fantastic. I can now fully understand the action. Never knew there was a float valve in the barrel jacket.

[@vbbsmyt]

I would call it a shuttle valve. The steam can enter the valve chamber either from the front or the rear of the barrel jacket. The tube in the upper part of the jacket carries steam from the rear When the gun is elevated, the valve slides to the rear blocking the inlet from the rear to prevent carry-over of water. If the gun is depressed, then the valve slides forwards. This feature is seen in all jacketed Maxim and Vickers MGs - but I never bothered to animate them before. Rob

[@lukelee5385]

Wow, this is a truely unique design. I guess it could count as a delayed blowback design but I would argue that it looks like a direct blowback design, since the levers and the spring is just one buffer system unlike roller delayed or lever delayed where there are two stages of action. I never thought it was possible to implement such a design in a full-power rifle cartridge, I wonder why it is not done more considering this is much simpler than the Maxim or Hotchkiss design.

[@MrMarinus18]

You can go bigger still. The 20mm Orliken AA gun was also delayed blowback. It's even pretty obvious as the spring is massive and external.

[@MrMarinus18]

One of the biggest advantages though is that delayed blowback made water cooling much easier. One of the fiddly things of a Maxim gun was that the barrel cycles back and forth through the water jacket which you somehow have to allow for while still creating a water tight seal.

[@aldodelaguila8222]

Hu Daniel Butka. Thanks. I only know the oiling in japanese machineguns, which in some conditions (dust in Manchuria) traped the particles and caused some misfires. Is the oiling system in the austro-hungarian MG quite different?

[@SpruceReduce8854]

Aldo del Aguila I think the Japanese mgs used a soaked brush to oil cartridges, while the schwarzlose uses a pump.

[@rajatdani619]

Bad news was just 2 years before ww1 this gun came into action.

[@markaplier1261]

At first this gun looks very good. But on further inspection i conclude it is unreliable. There is not a spring keeping pressure on the bolt at all times. Between the time the firing pin is tripped and when it hits the priner, the spring does not excercises pressure on the bolt, therefore not keeping it in battery. This leaves the potential for nasty out of battery detonations if the cartridge case erupts for example

[@vbbsmyt]

The notes to this animation point out that the Schwarzlose uses a delayed blow-back mechanism, using a series of levers and heavy breech to increase the inertia. It was used by the Austro-Hungarian Army and other European nations before WW1. It is clearly NOT unreliable. If you want further details on how it worked, please consult Col. Chinn USMC in Volume 1 of his book ‘The Machine Gun’ (1951) - Part 3, Chapter 11. He praises the simplicity and efficiency of employing a single large spring that acts as buffer, bolt return and firing pin spring.

[@pygame.d.cthulhu5263]

我中文描述一遍它的原理 施瓦茨罗斯M1912重机枪，外表上看起来有点马克沁机枪的影子，但实际上它开锁原理和马克沁机枪完全不同，内部机构与马克沁没有丝毫关系。 虽说施瓦茨罗斯M1912重机枪也有一点肘节枪机的样子，枪机也连在一个肘节上，但施瓦茨罗斯重机枪的肘节并不像传统的马克沁机枪那样通过枪管短促后坐开锁，而是直接由膛内压力推着枪机强行后退，把肘节强行扭转拉直暴力开锁，在这个过程中肘节只是为枪机后坐增加一些阻力。 因此施瓦茨罗斯重机枪的原理和马克沁机枪是完全不同的，该肘节不能刚性闭锁，只是提供一些阻力延迟后坐。 这种延迟开锁的半自由枪机原理优点是简单，比管退式、导气式等需要刚性闭锁机构的自动武器都简单，但缺点也很明显，虽然肘节能延迟开锁时机，但效果有限，枪机后退速度快，动作猛烈，抽壳时因为膛压还很高，弹壳膨胀紧贴枪管，造成抽壳阻力大，故障率高。对此施瓦茨罗斯使用了两个方法来解决这个问题，一个是在枪身内装一个油壶，每一发子弹进膛时油壶自动往枪膛内注入一点润滑油，减小抽壳时的阻力（视频里从00：10到00：25就演示了向油壶内注油，这就是注油的作用）；另一个是缩短枪管长度，让弹头尽快飞离枪口，使枪管泄压。但是后者的代价是降低了子弹初速，增大了枪口冲击波，枪口噪声和枪口焰都大，所以施瓦茨罗斯重机枪使用了一个外形大得夸张的喇叭形消焰器。​

Becuase it is a delayed blowback the breechblock starts moving the second that the powder is ignited, this is under high pressure. animations on guns are hard to do, although vbbsmyt's animations are very good you can't replicate the high speed of an actual weapon.

Why does it need to be charged 3 times? It looks like a round is pulled out of the belt and put into the chamber after the 2nd charging.

[@vbbsmyt]

Daniel, When loading a fresh belt, it is not possible to put the first cartridge in the feed wheel recess directly in front of the bolt. So the first charge action advances the feedwheel, sliding a rimmed cartridge under and behind the hook on the bolt. During the second charge action the hook pulls this cartridge out from the belt, and the third action loads it into the chamber. Rob

[@SpruceReduce8854]

vbbsmyt Thanks for the fast reply. When I can see the internals while firing, it looks like a cartridge is pulled from the belt and pushed into the chamber in only 1 cycle of the bolt. Is it any different when the belt is first being loaded?

[@vbbsmyt]

Daniel, You are right. I don't remember where I came up with the idea of cocking 3 times. I just watched a video of Russian enthusiasts firing a Schwarzlose, and, once the belt is in place, only one cocking action is necessary to get the round into the chamber. Oh dear! My bad.

[@SpruceReduce8854]

vbbsmyt I think it does need to be cocked 3 times if you are loading with the cover on (which is taken off in the video so you can see inside). Forgotten Weapons and the video game Tannenberg confirm this. My theory is with the cover on, the first cartridge can't initially access the "chamber" (idk what to call it) of the belt wheel that it does in the video. So you cock it twice to index the round twice so it's under the belt extractor, and once more to put it in the chamber.

[@vbbsmyt]

Thanks. Phew!
