Hi Klaas,
I think it is a device to block the turningmechanism of the cupola over the emplacement?

Or maybe is is an endswitch? I don't know of the cupola could rotate unlimited..
Gr, Tim

Thanx for the anwser it explains a lot,
I thought always that the cupola of the FLa 14 could turn 360º but that isn't so there is a begrenzung on it
so what to do with the dead corner of the placement ?

But the boomerang so I called was more a sort off hook or what ?

It looks the "boomerang" fix the turret in basic position (see the drawing). After the start of the rotation, the "boomerang" rotates slightly and then it stop the turret after its 360°rotation. There is a spring to soften the impact at the turret.

I do not know, how the electricity goes to the german 10,5cm FLAK. If there are usual cables, such kind of the device could prevent distorsion of the cables.

@ Ondrej Filip
The Cables came from below the kesselbettung and went through the centre of the Mittelpivot in to the chargebox
so there could not any distorsion of the cables be possible during the rotataition of the coupala

@ Jos
Is the drawing you sent witin this Topic a part of a larger drawing and is it possible to show the complete drawing ?

Even when the cables come in underneath the gun, it can't endlessly turn. The cables would be torn. With four guns in a row, and the rather unprecise Flak which doesn't need a direct hit, there was no need to turn the turret 360 degrees.

Correct. The maximum traverse is decided by the sockel- and gun-type combination. The turret is attached to the gun so it's traverse is limited. Without it, the turret rests on the ball bearings alone and had in theory infinite traverse.

A break is needed because of the sheer weight of the turret. When in traverse and reaching the maximum the momentum and sheer weight of the turret could overextend the maximum causing damage to the cables.

I think Klaas means there was a "rotation intake" (I do not know exact english term). In this case the turret can turn unlimitedly.

The function of the "Schwenkbegrenzung" device is clear. There must be some technical reason to stop the 10,5 FLAK gun after the 360°traverse. Maybe the cabels (if the gun has no rotation intake), maybe something different (if it has the rotation intake).

I do not see a real stop in the device shown .
Looking top down on the boomerang or banana you can see that the round thing on the cupola simply can pass. I think the device stops "schwankungen" or swinging of the cupola in the horizontal direction.

Off coarse if any cables are fix connected with the turret/cupola then you need a real stopper.

But maybe Jos can show the whole drawing (if possible) since there is also text on it which explain something.

Btw the "Federpuffer" , buffers or limits the vertical movement. In doing so they keep the cupola horizontal.
Thanks,

Wim

I think it works this way. Simple and effective.

Do not be confused with the first photo. This is damaged and inclined turret and the brake is higher than it should be.
