provide the shortest possible path of travel from the

Another generalized object is to provide a stationary
magazine for cooperation to the fullest extent possible
with a turret-supported pair of launcher arms rotated
axially above the magazine.
Other objects will become more apparent in the ensuing
description which is to follow. It is, however, to be

The particular di?iculties presented by this double cell

A further feature of considerable functional importance

tending cam 53 into the rammer head chamber is to permit
the rammer head to contact the cam and operate the
valve spool as the rammer head descends to engage and
pick up a missile. Normally, contact cam 53 is held in
an outwardly extended position by a coil spring 59
mounted between a shoulder 61 formed on the valve spool
and an interior wall of the valve body.
The function of latch cylinder control valve 52 is to
control hydraulic how to a latch cylinder 62 which, as
may be noted in FIG. 3, is bolted to support base 51 of
the latch assembly. More speci?cally, each latch cylinder
62 is stroked to operate a magazine missile latch arm 63
and an associated interlock switch 64. Actuation is
achieved by coupling a piston 66 and a connecting rod 67
of the cylinder to a latch drive shaft 68 which, in turn,
is drivably secured to latch arm 63. More speci?cally,
connecting rod 67 is linked by clevis 6? to the cylindrical
drive shaft so that extension or retraction of the piston

direction or the other.

The buffer assembly is formed principally of a buffer
lever arm 87 pivoted on the housing in such a position
that the aft launching shoe of the missile contacts it as
it rides downwardly in buffer extension rail 85 to force
the lever arm in a downward direction. The downwardly
movable end of the lever arm is provided with a yoke 38
that securely engages a buffer piston 89 mounted in a
cylinder 9?. which, as may be noted, is closed at its lower
end and ?tted with a suitable ?ll and bleeder plug that
may be used to replenish vfluid in a buffer reservoir to be
described. A cylinder head 92. closes the cylinder around
the piston at its upper end and the head-to-cylinder union
is sealed.
The piston protrudes from the cylinder at its
head end to attach to lever arm 87 and the upper end
‘of the piston is threaded to mount an accumulator 93
arm 63 by an upper link 71 which has one end securely
over an internal ?uid passage 94!- formed in the center
fastened to the upper end of the drive shaft and the other

The cam, moreover, is provided on its upper surface with
two beveled edges 111 and 112 culminating in a corner

sur'lice for present understanding to note only that the
lower end of the pawl is formed with an outwardly pro

cocked after it has been depressed over center.
The remaining structure of the rammer head and
other features of both the latch and buffer assemblies
will be apparent in the following description of the
schematic sequence illustrated in the drawings. In FIG.
6, it may be noted that the rammer head has progressed
downwardly in one of the rail extensions a sufficient
amount to cause its lower end portion to strike earn as

ever, it is critical that the ec entric pin be disposed a
precisely ?xed distance below the supporting blocks of
the latch or butler assembly so that it does not cause the
pawl to snap outwardly until the upper end of the pawl
has ridden beneath the missile shoe. Obviously, the
rammer head then can be retracted from the missile maga
zine without engaging a missile.
The operation or" the entire apparatus should be rea
sonably apparent from the foregoing desc

ever, to summarize, the missile magazine cooperates with
the launcher arm hoisting mechanism by providing a
plurality of individual cells arranged in concentric rings,
each cell being provided with a pair of rails either one of

the scope of the appended claims the invention may be
practiced otherwise than as speci?cally described.
