Installed on the rifle
Like many army entered the First World War, the French army very soon felt the need for a statement on the arms rifle grenades. There were several versions of this much-needed weapons, they were mostly German and English imitation shompolnye grenades.
As you know, shompolnye garnet during its simplicity has a significant drawback - because ramrod made of pretty solid iron, he rubs after a short application rifling, and in the muzzle, which affects the accuracy of fire from rifles. Furthermore, the use of grenades requires attention and shot live ammunition, it is possible in a combat situation, can lead to an accident. Finally, charge the gun with blanks before removing it, or combat shooting from the store long and awkward.
Decision was the invention of complex "weapon-munition" as mortars - "cup", worn over the barrel of his rifle and grenades with simple percussion fuse. The system was named Viven-Bessiere named after its inventor, often abbreviated as VB.
mortars was very simple in design, introducing a tube larger than the barrel diameter, with a socket to fit over the barrel. Bayonet coupling had (L-shaped) cut-out, Kojima and was attached to the rifle barrel, fixed on the basis of flies. Americans, putting into service this system produced mortars based compatibility with their weapons, later adding more securely locking screw cutout (instead of the L-shaped).
Construction mortars became a kind of "classic", was copied by the Germans, they are actively used, in a modified form has been applied in the next world war.

particularly interesting design grenade was that in the central part of the tube grenade had to skip combat bullet cartridge that produces a shot. In front of the canal was closed by a membrane, which the bullet pierces the passing of the energy grenade. Push also reports gases burnt gunpowder charge.

This grenade was a little harder than BB and housed, but completely excluded cases involving erroneous shot live ammunition, less time was spent on loading rifle and shot supply problem special blanks.
system design Viven-Bessiere (VB)
grenade consisted of housing in the form of a cylinder with a few rounded head portion, the central tube, and fuse plugs. Inside the enclosure had a notch to increase fragmentation in the blast. French grenades were made of cast iron, American of low-grade steel.
Length grenade was about 64 mm, about 51 mm caliber. Weight about 480 grams.
Range grenade was about 185 meters, and the radius of splinter estimated at 70 meters. However, it is rather safe distance away from the break - judging by the mass grenades radius continuous defeat did not exceed 25-30 m
grenade were developed three types of ammunition: grenade, "connected" pomegranate and pomegranate container with bursting charge, which could equip oneself toxic substances, incendiary compositions or producing agent.
Regardless of the equipment
last munition had the same structure.
«Telecommunication grenade" is a container into which the message and a small charge of smoke producing substance. The idea designer, such pomegranate could "smuggle" a message asking for help in the case, for example, surrounding the enemy. Smoke composition should indicate the place was falling grenades. In practice, this device proved useless - look under the fallen fire grenade was uncomfortable, as well as writing a note, leading the fight in the environment. Small charge of the flue can not accurately determine the location of the fall of grenades "news».
