Another generalized object is to provide a stationary

Other objects will become more apparent in the ensuing
description which is to follow. It is, however, to be

a pair of launcher arms, the launching system is capable
of picking up two missiles at a time, although, if desired,
either arm can be loaded respectively.

drive is that it is so regulated as to permit either a long

of the rammer head into the missile cells can be regulated
so as to provide a long stroke or a short one.

A further feature of considerable functional importance
To satisfy this requirement, each magazine cell includes
is the use of a pin-shaped cam 82 mounted in a bore in

rail extension 47. The rather obvious purpose of so ex
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
and rod rotates the drive shaft on its vertical axis in one
direction or the other.
At its upper end, drive shaft 68 is coupled to latch

it is run through this particular rail. Consequently, re

assembly rail 41 or the bu?er assembly rail 4-2, the ram
rner head is capable of releasing the latch since it will
contact one or the other of the cam surfaces of the ‘control
valves.
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
pinned to the latch arm. Normally, latch arm is urged

and, at its upper end, is formed with an outwardly pro
sile shoe to maintain engagement of the shoe. Roller
jecting ?ange or dog portion l€l7 adapted to extend over
the top of the missile shoe to cooperate with pawl 1&4
in latching the shoe for hoisting or lowering operations.
Also, ?nger 103 mounts on its upper rearward corner
a roller £63 the purpose of which will become clearer.
Pawl Hi4 also is pivotally mounted on the rammer
1% carried by the ?nger, provides a smooth engagement
between the rear of the linger and curved surface ‘116.
When it is desired to lower the missile into the maga
zine and tnen retract the rammer head without reengag~
ing the missile, the action of the previously described
head body and, in its normal position, it is rocked out
member occurs in the manner illustrated in schematic
wardly of the body by spring pressed cam 106 so as to
FIGS. 10, 11 and 12. Brie?y, this particular operation
is accomplished by utilizing. the previously-mentioned
present a latching ?ange 1&9 for engaging and picking
‘up the missile by means of its aft launching shoes 11.
The cam, moreover, is provided on its upper surface with
two beveled edges 111 and 112 culminating in a corner
113 and, normally, its beveled edge 111 is spring pressed
into contact with the pawl. However, if the pawl is de
pressed rearwardly into the rammer body a sumcient
amount, it will snap over center of the cam to then permit
its beveled surface ill to engage the pawl. Such an
long rammer head stroke, or in other words, a stroke
that is longer than the stroke previously used in the mis
sile pick-up action. FIG. 10 represents the upper limit
of the long stroke in that the ramrner head must be low
ered sufficiently to cause eccentric pin 52 to depress the
rammer head an amount sufficient to cause the lower
corner of the pawl to ride over upper corner 113 of cam
engagement then rocks the pawl in the opposite direc
tion to hold the pawl’s latching ?ange 169 in a depressed
1&6. When this occurs, the pawl obviously will snap
to the completely depressed position illustrated in the
drawing. With the cam held in its depressed position,
or retracted position. Also, pawl will is formed with a
beveled surface at its lower end and it is this beveled sur
face which normally engages beveled surface ill of the
cam. it will become apparent that other contours of the 60
may be noted in PEG. l‘l, eccentric pin 82. rides on the
?at surfaces of the ram-mer head pawl to gradually de
press the rearward portion of the pawl and cause its low
pawl are functionally signi?cant,
lowever, it should
sur'lice for present understanding to note only that the
lower end of the pawl is formed with an outwardly pro
jecting ?ange ?le which permits the pawl to be reset or
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
latch control mechanism 84- to release the missile
latch.
As seen, pawl til-4 is just commencing to strike
aft missile shoe 11 so as to be depressed rearwardly or,
the rammer head then can be moved upwardly and, as
er corner to approach the over~center corner of the cam.
Finally, eccentric pin
rides onto outer ?ange 11% at
the lower end of
pawl to depress this lower end an
amount sufficient to again throw the pawl over center
and into its normal outwardly projecting position.
How
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
'on. How
