Termination accumulator

Claim 2

In an automatic machine gun having a feed system for feeding ammunition to at least one firing chamber, a supply conveyor section for supplying ammunition to the feed system, and a trigger mechanism for actuating said gun, the improvement comprising: a bypass means to receive ammunition from said supply conveyor section; a gating means operably moveable between two positions; said gating means constructed for allowing ammunition to pass from the supply conveyor section to the feed system when in the first position and for diverting ammunition from the supply conveyor section to the bypass means thereby preventing live ammunition from entering the feed system when in the second position; means for moving the gating means to the first and second positions; said trigger mechanism operably connected to said moving means for positioning said gating means in its second position upon release of said trigger mechanism; means for continuing forward operation of the feed system upon release of said trigger mechanism until all ammunition in the feed system has been fired; said bypass means having sufficient capacity to accommodate ammunition diverted therein from said supply conveyor section while the ammunition in the feed system is being fired after release of said trigger mechanism; the supply conveyor section constructed for continuing forward movement when the gating means is moved to its second postiion to supply ammunition to the bypass means during forward operation of the feed system until all ammunition therein has been fired.

Claim 3

An automatic machine gun as defined in claim 1 further comprising; a return conveyor section leading from the feeding system for transporting spent ammunition therefrom, the return conveyor section being partitioned into compartments, each compartment sized to receive one round of ammunition; the bypass means being connected at one end to the return conveyor section; the bypass means comprises a channel with a conveyor section passing therethrough; said bypass conveyor section being of sufficient length to accommodate the same number of rounds of ammunition as the number of rounds of ammunition and spent ammunition in the feed system between the points where the bypass means connects to the supply conveyor section and where the bypass means connects to the return conveyor section such that each compartment of the return conveyor section receives a single round of ammunition from either the bypass means or the feed system.

Claim 4

An automatic machine gun as defined in claim 2 comprising; a reversing means for reversing the direction of the bypass conveyor section and supply conveyor section to return ammunition in the bypass conveyor section to the supply conveyor section such that ammunition returned to the supply conveyor section is supplied to the feed system during the next burst of ammunition.

Claim 5

An automatic machine gun as defined in claim 3 wherein the reversing means reverses direction of the return conveyor section; a second gating means is mounted at the junction of the bypass conveyor section to the return conveyor section diverting said spent ammunition to said bypass means thereby preventing spent ammunition that is on the return conveyor section from being sent back through the outlet of the feed system.

Claim 6

An automatic machine gun as defined in claim 2 or 4 wherein a single handling conveyor belt forms the supply conveyor section, bypass conveyor section and return conveyor section; said handling conveyor belt constructed into sequentially spaced compartments, each compartment receiving a single round of linkless ammunition; said handling conveyor belt operably positioned adjacent a feed conveyor belt which receives ammunition from said handling conveyor belt at said supply conveyor section when said gating means are in their first position said feed conveyor belt feeds said ammunition to said firing chambers; said handling conveyor belt operably positioned adjacent an output conveyor belt which receives spent ammunition from said firing chambers and conveys it and passes it onto said return conveyor section of said handling conveyor belt; said bypass conveyor section being convoluted between said supply conveyor section and said return conveyor section.

Claim 7

A termination accumulator for an article handling system having an inlet, outlet and work station, said accumulator comprising; a supply conveyor means operably connectable to an intake of the article handling system; a return conveyor means operably connectable to an outlet of the article handling system for receiving articles therefrom; a bypass channel including a conveyor means operably connected at one end to the supply conveyor means adjacent the gating means and at an opposing end to the return conveyor means; a gating means operable between two positions for allowing passage of articles from the supply conveyor means to the handling system when the gating means are in a first position for preventing passage of articles to the work station and diverting said articles to the bypass channel when the gating means are in a second position; means for sequentially advancing the articles in the article handling system to the work station and sequentially advancing the supply conveyor means; a termination switch to deactuate said article handling system; said gate means operably connected to said termination switch to move to said second position upon actuation of said switch; said advancing means connected to said termination switch to continue to advance said articles after said termination switch is actuated such that the work station receives all the articles that passed the gate means and the bypass conveyor means receives articles from the supply conveyor means; reversing means for reversing the supply conveyor means and bypass conveyor means such that articles on the bypass conveyor means are returned to the supply conveyor means when the article handling system is empty whereby articles returned to the supply conveyor means are supplied to the article handling system during the next forward operation of the article handling system; a second gating means mounted at the junction of the bypass channel and return conveyor means for diverting said articles on said return conveyor means to said bypass channel, thereby preventing articles passed from the work station to the return conveyor to pass back into said work station.

Claim 8

A termination accumulator for an article handling system having an inlet, outlet and work station, said accumulator comprising; a supply conveyor means operably connectable to an intake of the article handling system; a return conveyor means operably connectable to an outlet of the article handling system for receiving articles therefrom; a bypass channel including a conveyor means operably connected at one end to the supply conveyor means adjacent the gating means and at an opposing end to the return conveyor means; a gating means operable between two positions for allowing passage of articles from the supply conveyor means to the handling system when the gating means are in a first position for preventing passage of articles to the work station and diverting said articles to the bypass channel when the gating means are in a second position; means for sequentially advancing the articles in the article handling system to the work station and sequentially advancing the supply conveyor means; a termination switch to deactuate said article handling system; said gate means operably connected to said termination switch to move to said second position upon actuation of said switch; said advancing means connected to said termination switch to continue to advance said articles after said termination switch is actuated such that the work station receives all the articles that passed the gate means and the bypass conveyor means receives articles from the supply conveyor means; reversing means for reversing the supply conveyor means and bypass conveyor means such that articles on the bypass conveyor means are returned to the supply conveyor means when the article handling system is empty whereby articles returned to the supply conveyor means are supplied to the article handling system during the next forward operation of the article handling system; a second gating means mounted at the junction of the bypass channel and return conveyor means for diverting said articles on said return conveyor means to said bypass channel, thereby preventing articles passed from the work station to the return conveyor to pass back into said work station.
