push rightward in fig4 against stop 96 of frame 52 whereby block 60 and the rest of frame 52 move to the right relative to stationary member 54 frame 52 slides on stationary member 54 and remains fixed relative to evacuator 42 as evacuator 42 translates with the cannon the stationary member is kept from moving leftward away from turret member wall 66 fig2 by a series of connectors the first connector is a shackle 62 held to stationary member 54 by means of quick release pin 64 connected to shackle 62 is a turnbuckle 67 which is in turn connected to another shackle 68 shackle 68 is connected to turret bracket 70 by means of quick release pin 72 turnbuckle 67 is itself comprised of eyes 69 and 71 and body 73 stationary member 54 is prevented from rightward movement by cylinder 50 since cylinder 50 is attached to member 54 and exerts a rightward force on stop 96 of frame 52 during actuation cylinder 50 exerts a leftward reactionary force on stationary member 54 this leftward reactionary force prevents rightward movement of stationary member 54 shown in fig3 through 6 are further details of mounted cylinder assembly 48 one piece frame 52 has a rearward block.
