DEFINITIONS
ACCELERATOR - BELT FEED

ACCELERATOR
A device such as a pivot lever attached to a short-recoil assembly that increases rapid movement of the rearward action of the bolt for increasing cyclic rate of fire.

AIR-COOLED
The cooling of gun components by atmospheric radiation and circulation.

AUTOMATIC
A weapon which travels through a complete operating cycle continuously from a single function of the trigger without releasing it.

BARREL LINER
An inner sleeve inserted into the barrel to prevent rapid wear from friction and heat. An ordinary application would be on automatic weapons to increase barrel life.

BATTERY [IN BATTERY]
When all component mechanisms in a firearm are in their final position, [locked], ready for firing of the cartridge.

BELT FEED
A system for feeding ammunition into automatic weapons on a continuous basis. The belts may be a predetermined length or continuous depending upon the type of belt used. Original designs were two canvas strips stitched together to form open-ended pockets for the cartridges to slide into. Extraction of the cartridge from the belt was a method to withdraw it in a backward movement, raise or lower for alignment and finally pushed into the barrel chamber. The belt was advanced automatically for succeeding round positioning.

An improved design was canvas belting with metal clips attached to hold the cartridges in place. The open top clips allowed the round to be pushed directly from the belt into the barrel chamber by the weapon’s bolt thus eliminating some of the mechanism action.

A further advance system necessitated by usage of machine guns for aircraft was designed using ‘disintegrating links’. It was composed of individual metal clips or holders for each cartridge whereby the cartridges provide the linking function themselves. Its advantages did away with the cumbersome fabric belting with potential jamming of the material during the exit stage and the elimination of empty belt storage containers. The metal clips could be automatically discarded along with the empty shell casings from the aircraft. This system was also an advantage where long and continuous runs of belting were needed in remote locations of aircraft such as enclosed wing gun mountings.
