How many revolvers are there 20

revolver

A revolver is a multi-shot pistol, and thus a handgun with a single handle, which is enclosed by the firing hand. The cartridges or charges are attached to a revolver in a device which is brought into the firing position by a rotary movement. The most common form of the today Revolvers is the drum revolver.

variants

Drum revolver: With these Revolvers the cartridges or charges are housed in a drum rotating towards the barrel core. During the firing sequence, this drum is rotated and a fresh cartridge or charge is brought in front of the barrel. The drum acts as a chamber.

Bundle revolver: This type has multiple circular barrels, each of which carries a cartridge or charge. These barrels are rotated during the firing sequence. After each shot, another barrel with a fresh charge is brought into the firing position.

Disk turret: English "Turret Revolver" carry their cartridges or charges in a disc, which after the shot rotate on an axis vertical to the barrel axis. In this way, fresh cartridges or charges are brought in front of the barrel. The disc serves as a chamber.

Chain revolver: This one revolver-Type carries prepared charges or cartridges in chambers, which are connected to a round chain. During the firing sequence, these limbs are gradually brought in front of the barrel.

Magazine revolver: some revolvers have an additional cartridge prefix in a magazine. However, these cartridges are not loaded into a cartridge chamber connected to the barrel, as is the case with a self-loading pistol, but inserted into the revolver barrel or chain.

mechanics

There are basically four different versions of trigger mechanisms Revolvers.

Single action revolver, must be cocked by hand on the hammer after each individual shot has been fired. In most cases, the rotation of the multi-loading device is also taken over.

Cocked trigger (double-action) revolver, here cocking the cock and rotating the multi-loading device can be done by pulling the trigger on the pistol. However, this goes with a higher separation path and separation resistance. Clamping trigger turrets can also be clamped by hand and used like single trigger turrets. The pull-off travel and pull-off resistance usually decrease considerably during pre-tensioning.

DAO (Double-Action Only) revolver, are identical to the Sapp trigger turret, only the possibility of pre-tensioning them by hand is missing.

Automatic revolver, These revolvers are able to start the tap and rotate the multi-loading device via an automatic, mostly recoil loading.

history

Samuel Colt is often incorrectly referred to as the inventor of the revolver, but there were experiments with a similar functional principle long before him. As early as the 18th century there were flintlock variants of a revolver-like firearm, but this research soon became limited. It was only after the turn of the 19th century and with the invention of the primer that multi-shot weapons could be further developed. The biggest problem was getting the drum exactly aligned in front of the barrel. In the early attempts there were a lot of setbacks in the form of quasi-bullet guns. The bundle revolver (also Pepperbox called). A single-run construction was dispensed with here; 6 or 8 runs were simply combined. However, this came at the expense of weight and handiness.

In 1834 Samuel Colt returned to the USA from England by ship. He watched as the helmsman locked his rudder with the help of a wooden bolt from below. This kept the rudder straight and the ship on course. Colt was enthusiastic about this mechanism and immediately carved a model of his idea. In the same year he had a model made by the gunsmith Patterson. The Colt-Patterson model was born. In 1836 Colt got his patent and thus it was possible to develop the first working and safe Colt models. The only achievement was a small metal bolt that snaps into a recess on the drum and thus enables the drum to be securely locked in place before the barrel. Thus began the era of the percussion revolver:

Percussion revolver

A percussion revolver is nothing more than a muzzle-loading weapon. The drum is open towards the front to hold gunpowder and a projectile. At the back of the drum has a piston that picks up the primer. The drum can be loaded with the help of a loading lever (loading ram). Originally the revolver was loaded with a round ball, but the projectile shape that is common today soon established itself. In order to be able to load the revolver faster, cartridges were prefabricated from paper. The Sagittarius made these himself or could even buy them.

Between 1850 and 1870 there was an abundance of manufacturers of percussion revolvers.

Cartridge revolver

When the industrially manufactured brass cartridge began its triumphant advance in the early 1870s, the revolvers were also converted for it. The first modifications (so-called conversions) were self-designed patents such as a percussion revolver could be converted into a cartridge revolver. Soon, however, some models came on the market that were matched to the cartridges customary at the time. At the beginning, the market hadn't really agreed on a system.

There were pen fire revolvers such as B. the Lefaucheux revolver. The propellant charge was ignited by means of an ignition charge, which in turn was ignited by a pin located on the outside of the case edge. The hammer hit the pin from above, driving it into the priming charge, etc. The problem with these weapons was that each cartridge had to be precisely inserted into the drum, with the pin in a recess in the drum chamber. (See also Lefaucheux ignition)

Then came the rimfire cartridges, which were originally used for lever action rifles. (See Henry Rifle or Winchester). Smith & Wesson had the Rim-Fire System in use with the Model No. 1 to 3. Mercury fulminated in the lower edge of the cartridge; if the hammer hit the edge of the cartridge, the propellant charge could be ignited.

Finally, the central fire cartridge (see central fire ignition) was able to prevail. A primer was incorporated in the middle of the cartridge base. The hammer hit the primer with a thorn, which ignites the propellant charge.


From this point on, one could speak of a modern revolver, which actually has hardly changed since the turn of the 19th and 20th centuries. The main difference lies in the shape of the charging option. While in the older models the cartridges had to be loaded and unloaded individually from the side through a loading chamber, drop barrel models came later on the market. Ultimately, the swing-out drum established itself, which enabled much faster loading and unloading. Reloading is done by hand either individually or by means of pre-assembled bundles, the so-called "speedloaders", which push six or more cartridges into the empty chambers at the same time after ejecting the empty cartridges, thus guaranteeing a much faster firing sequence. Use speed loaders, among others. Police and security services.

Double-action revolver with swing-out drum

particularities

As a rule, six cartridges are housed in the drum, which earned this type of weapon the nickname "sixgun" or "six-shoter". There are also five-, seven- and eight-shot models (e.g. the light Smith & Wesson AirLite) or models like the nine-shot LeMat revolver, which could also fire a shot in the middle. There were also early models with a retractable knife or stiletto.

Other weapons on the revolver principle

The "revolver principle" is also used in the area of ​​machine guns and machine cannons. In the "Gatling-Gun", patented in 1862 after its inventor Richard Jordan Gatling, a barrel set including locks rotates continuously around a common axis. The rear part of the system is in a fixed sleeve with a hand crank for driving. Curved millings in the cylindrical part of the sleeve open and close the locks in the course of a rotation. The cartridge is fed in at the top and the shot is fired at the bottom. The continuous loading process allows high rates of up to 1200 rounds / min, and the barrels overheat less than with single-barreled weapons. The hand-operated Gatling guns were superseded by the automatic machine guns at the end of the 19th century.
