Linkless ammunition gun transfer unit

Claim 2

A linkless ammunition gun transfer unit for the conversion of a linked-ammunition firing gun, having an ammunition feeder assembly, to a linkless-ammunition firing gun, said linkless-ammunition gun transfer unit comprising: drive train means for engaging ammunition feed sprockets disposed in said ammunition feeder assembly; plate means, configured for attachment to said ammunition feeder assembly, for supporting said drive train means; and coupling means for removably attaching a linkless-ammunition feed chute to the ammunition feeder assembly and aligning the ammunition feed sprockets in the ammunition feeder assembly with ammunition transfer sprockets disposed in said linkless-ammunition feed chute to enable transfer of linkless-ammunition rounds therebetween, said coupling means engaging the drive train means when the feed chute is attached to the ammunition feeder assembly for transferring power from the ammunition feed sprockets to the transfer sprockets in order to move ammunition through said ammunition feed chute.

Claim 3

The linkless ammunition gun transfer unit according to claim 1 wherein the coupling means further comprises a transversely moveable shaft configured for passing through the ammunition transfer sprockets disposed in said feed chute.

Claim 4

The linkless-ammunition gun transfer unit according to claim 2 wherein the coupling means further comprises spline means, disposed on said transversely moveable shaft, configured for engaging a spline disposed in the ammunition transfer sprockets in said ammunition feed chute.

Claim 5

The linkless ammunition gun transfer unit according to claim 3 wherein the coupling means further comprises a manually removable quick disconnect pin means for engaging said transversely moveable shaft to selectively prevent transverse movement thereof.

Claim 6

The apparatus according to claim 4 wherein the coupling means further comprises clevis block means for engaging said transversely moveable shaft, sad clevis block means being configured for attachment to mechanical fittings for supporting link strippers on said ammunition feed assembly, and said transversely moveable shaft being configured for passing through the clevis block means.

Claim 7

The apparatus according to claim 5 wherein the drive train means comprises a gear train configured with a profile smaller than the profile of the plate means and the plate means has dimensions enabling the plate means to be mounted to the existing ammunition feeder assembly without significant protrusion therefrom.

Claim 8

A linkless-ammunition gun transfer unit for the conversion of a linked-ammunition firing gun, having an ammunition feeder assembly, to a linkless-ammunition firing gun, said linkless ammunition gun transfer unit comprising; drive train means for engaging ammunition feed sprockets disposed in said ammunition feeder assembly; plate means, configured for attachment to said ammunition feeder assembly, for supporting said drive train means; and coupling means for removably attaching two linkless ammunition feed chutes to the ammunition feeder assembly and aligning the ammunition feed sprockets in the ammunition feeder assembly with ammunition transfer sprockets disposed in each of said two linkless ammunition freed chutes to enable transfer of linkless ammunition from either of the two linkless ammunition feed chutes into said ammunition feeder assembly, said coupling means engaging the drive train means when the feed chutes are attached to the ammunition feed sprockets to the transfer sprockets in each of the two linkless ammunition feed chutes in order to move ammunition through said ammunition feed chutes.

Claim 9

A linkless-ammunition gun transfer unit for the conversion of a linked-ammunition firing gun, having an ammunition feeder assembly, to a linkless-ammunition firing gun, said linkless ammunition gun transfer unit comprising; drive train means for engaging ammunition feed sprockets disposed in said ammunition feeder assembly; plate means, configured for attachment to said ammunition feeder assembly, for supporting said drive train means; and coupling means for removably attaching two linkless ammunition feed chutes to the ammunition feeder assembly and aligning the ammunition feed sprockets in the ammunition feeder assembly with ammunition transfer sprockets disposed in each of said two linkless ammunition freed chutes to enable transfer of linkless ammunition from either of the two linkless ammunition feed chutes into said ammunition feeder assembly, said coupling means engaging the drive train means when the feed chutes are attached to the ammunition feed sprockets to the transfer sprockets in each of the two linkless ammunition feed chutes in order to move ammunition through said ammunition feed chutes.

Claim 10

The linkless-ammunition gun transfer unit according to claim 8 wherein the coupling means further comprises two transversely moveable shafts, each shaft being configured for passing through the ammunition transfer sprockets disposed in one of said feed chutes.

Claim 11

The linkless-ammunition gun transfer unit according to claim 8 wherein the coupling means further comprises spline means, disposed on each of said transversely moveable shafts, and configured for engaging a keyway disposed in the ammunition transfer sprockets in each of said ammunition feed chutes.

Claim 12

The linkless-ammunition gun transfer unit according to claim 9 wherein the coupling means further comprises manually removable quick disconnect pin means for engaging said transversely moveable shafts to selectively prevent transverse movement thereof.

Claim 13

The apparatus according to claim 10 wherein the coupling means further comprises a clevis block means for engaging said transversely moveable shaft, said clevis block means being configured for attachment to mechanical fittings for supporting link strippers on said ammunition feed assembly, and said transversely moveable shaft being configured for passing through the clevis block means.

Claim 14

The apparatus according to claim 11 wherein the drive train means comprises a gear train configured with a profile smaller than the profile of the plate means and the plate means has dimensions enabling the plate means to be mounted to the existing ammunition feeder assembly without significant protrusion therefrom.
