Machine gun M1895/1914 Colt

John M. Browning in 1889, has developed the design of a machine gun. For the base, he took a circuit with air cooling of the barrel and the removal of powder gases. With all of this Browning decided not to use the vent path and made a rocking piston. In the end, a light machine gun came comparable. In 1890, Browning sold the rights to create a machine-gun company "Colt", which in 1895 released gun, given the name "Colt» M1895. The South American Defense Ministry data guns purchased in small amounts. In addition, they were sold to England (first the war, they were used as training), Italy, Spain and some countries in Latin America.

Gas operated engine was a unique scheme. Powder gases, after passing through the open hole in the wall of the barrel bottom, discarded piston mounted on the end of a longish shoulder crank — rocker crank. Connecting rod, turning 170 degrees, drives the crank (second lever) coupled to the gate through a sliding bar. Lath (Bolt carrier) is the leading element of the system. She, moving backwards, worked on the lug bolt shaped neckline. After lowering the rear of the bolt out of engagement with the bearing surface receiver — performed unlocking the barrel. Planck's continuing movement relegated back the bolt and spring-loaded ejector valve sleeve is pulled out of the chamber. Liner hits the slide in the slot shutter tooth socket receiver and a lead-out window in the receiver is pushed out to the right. With all of this was compressed revertible pair of springs mounted in tubes under the barrel. Pivoting ear and stocks combined spring and rod kutsee shoulder, turned him forward, returning the mobile system to the initial position, the shutter shall be sent to the cartridge chamber, and when the trigger was pressed, carried out subsequent shot. The stroke length of the system was equal to 102 millimeters. Due to a corresponding movement of the piston and the dust lifted off take down the gas, machine gun M1895/1914 "Colt" was nicknamed «Potato Digger» — «potato digger." It was the view that the air intake after each shot produced ennobled cooling of the barrel, but in reality it has provided only purge gas outlet openings.

In the tubular back plate installed trigger firing mechanism with helical mainspring and rectilinear motion of the hammer. The trigger is included self-timer and open the trigger. On the right side of the installed safety lever that locks the trigger. Handle reloading was under the piston at the end of the connecting rod. This handle for manually reloading tied the cord, the other end was mounted on the back plate. In general, and more than was comfortable circuit having a rocker arm and a block. On the back plate there was a control knob.

Meals are made from a linen gun cartridge tape is designed for 100 patrons. The system of power input of the receiver drum driven by a sliding plate, extractor, the device supplying the cartridge. The drum had two zubchatki — front lock the cartridge into the tape over the bullet back — for sleeve. Rocker arm supply created turn the drum. Arm was attached to the right wall of the receiver and contacted swinging feeder. Rotate the drum to the right to prevent the special dog. The cartridge was in the chamber of the tape followed properly. While driving back strap lug it pulled the tail of the feeder, the drive lever feed. The tail of the feeder jumped over the tooth drum, without turning. During the revolving movement of the arm rotation occurred revolving parts, with all this tooth feed lever turned the drum on a step, and the cartridge was facing the window receiver. Cartridge from the tape has been removed for a spring-loaded extractor rim. Extractor was mounted on a bracket and moved cartridge on the tray feeding device. Once the cartridge has been removed from the tape absolutely comb plates pulled the dog tray, which raised the cartridge to exit the frame extractor at this time let the cartridge and stop the movement of the tray so as not to interfere with the extraction of spent cartridges. During the movement of the working strip dovorachivat tray, with all this cartridge moved to a receiver box receiver, where picked up by the gate. Comb while entering the cartridge extricated dog tray and the tray fell. The projection plates pressed on the feeder, and the subsequent drum cartridge supplied. The design of the machine gun had 137 items.

Machine gun mounted on a tripod machine, consisting of a base, to which were attached one back and two front legs (hinged), swivel rocker part of worm gear mechanism with a vertical arc to hum.

For example, the first 1,750 guns were delivered with the highest so-called "French" tripod (a tripod company "Colt" delivered to France), with their slide was strengthened. General Shoemakers made significant efforts in order to "Colt" and "Marlin" began to supply "low" tripod. It turned out that the boards, which size is 685×445 mm, safer to do on Izhorskij in. They were used for 6.5-mm armor steel.
