Claims
- 1. Gun mounting apparatus comprising:
- cradle means for supporting a fixed outer trunion sleeve;
- inner trunion sleeve means, slidably supported within said fixed outer trunion sleeve having a socket in one end thereof for engaging a gun trunion;
- pin means disposed in said fixed outer trunion sleeve, for engaging a helical groove disposed in said inner trunion sleeve means in order to cause precise axial movement of said inner trunion sleeve means as it is rotated within said fixed outer trunion sleeve from a first position at which said socket disengages the gun trunion to a second position at which said socket engages the gun trunion; and
- means for releasably locking said inner trunion sleeve means to said fixed outer trunion sleeve in said second position.
- 2. The gun mounting apparatus according to claim 1 wherein said means for releasably locking said inner trunion sleeve means comprises:
- a plunger slidably disposed within said inner trunion sleeve means and extending outward from an opposite end thereof;
- means for defining an aperture through said fixed outer trunion sleeve;
- means for defining an aperture through said inner trunion sleeve means, the fixed outer trunion sleeve aperture and the inner trunion sleeve means aperture being aligned when said inner trunion sleeve means is in said second position;
- ball means disposed within the inner trunion sleeve means aperture for engaging the fixed outer trunion sleeve aperture when said inner trunion sleeve means is in said second position, said ball means being held in engagement with the fixed outer trunion sleeve aperture by said plunger; and
- groove means disposed in said plunger in a spaced apart relationship with the inner trunion sleeve means aperture for receiving said ball means when said plunger is slid into a position aligning said groove means with the fixed outer trunion sleeve aperture to unlock the inner trunion sleeve means from the fixed outer trunion sleeve and enable the inner trunion sleeve means to be moved from the second position to the first position.
- 3. The gun mounting apparatus according to claim 2 further comprising means defining a slot in said fixed outer trunion sleeve, for enabling said gun trunion to be placed into said inner trunion sleeve means socket as the inner trunion sleeve means is moved from the first to the second position.
- 4. The gun mounting apparatus according to claim 3 further comprising means for releasably attaching said fixed outer trunion sleeve to said cradle means.
- 5. The gun mounting apparatus according to claim 1 further comprising two cradle means, disposed in a spaced apart relation, for supporting first and second trunion sleeve assembly in a position for engaging the gun trunion.
- 6. The gun mounting apparatus according to claim 5 wherein each trunion sleeve assembly comprises interchangeable fixed outer trunion sleeve and interchangeable inner trunion sleeve means, each slidably supported within a fixed outer trunion sleeve for engaging a gun trunion.
