Abstract
Abstract A missile launcher is provided with pyrotechnically-operated means for jettisoning the missile. The missile is hung under a sub-rail latched to the underside of the main launcher body and upon operation of the jettisoning means the sub-rail/missile combination is slid rearwardly to disengage the latches after which the combination is given a downward thrust away from the launcher body, the thrust being imparted just forward of the collective center of gravity of the missile/launcher combination to cause its downward departure to be assisted by negative lift. The jettisoning means may consist of a lever and linkage actuated by a gas-operated piston-and-cylinder.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
66 words
An airborne missile launcher, comprising: a main missile launcher, a sub-rail for detachable attachment of a missile, detachable connection means for detachably connecting said sub-rail to said launcher, jettison means for disconnecting and jettisoning said sub-rail from said launcher, actuating means for actuating said jettison means where actuating said jettison means causes detachment of said connection means and disconnects and jettisons said sub-rail from said launcher.
Claim 2
Dependent Claim
66 words
An airborne missile launcher, comprising: a main missile launcher, a sub-rail for detachable attachment of a missile, detachable connection means for detachably connecting said sub-rail to said launcher, jettison means for disconnecting and jettisoning said sub-rail from said launcher, actuating means for actuating said jettison means where actuating said jettison means causes detachment of said connection means and disconnects and jettisons said sub-rail from said launcher.
Claim 3
Dependent Claim
13 words
A launcher according to claim 1, where said actuating means is pyrotechnic means.
Claim 4
Dependent Claim
45 words
A launcher according to claim 1 or claim 2, where said detachable connection means is a latch and said jettisoning means is arranged to slide the sub-rail longitudinally for disconnecting said latch and further including thrust means for imparting a downward thrust to the sub-rail.
Claim 5
Dependent Claim
53 words
A launcher according to claim 3, where a missile is secured to the sub-rail and said jettisoning means is said thrust means which is arranged to impart the downward thrust to the sub-rail at a position a short distance forward of the collective center of gravity of the sub-rail combined with the missile.
Claim 6
Dependent Claim
62 words
A launcher according to claim 1, where the jettisoning means comprises a gas-operated piston-and-cylinder and the launcher further comprises a lever including an upper end and a lower end, a linkage upon which said jettison means acts, and an abutment on said sub-rail, whereupon actuation of said jettisoning means causes said lever to thrust first rearwardly and then downwardly on the sub-rail.
Claim 7
Dependent Claim
73 words
A launcher according to claim 5, where the piston-and-cylinder is disposed horizontally and is coupled to the upper end of said lever, said lever is inclined rearwardly and downwardly with its lower end in engagement with said abutment on the sub-rail, said linkage has a lower end pivotally connected to a point on the lever intermediate the lever ends, and said linkage extends upwardly and rearwardly from said pivotal connection to the lever.
Claim 8
Dependent Claim
22 words
A launcher according to claim 6 further including guide means for constraining movement of the upper lever to slide horizontally and rearwardly.
Claim 9
Dependent Claim
73 words
A launcher according to claim 7, wherein said linkage and guide means are arranged such that the rearwardly sliding upper end of the linkage reaches the end of the guide means and is arrested before the end of the piston stroke of the piston-and-cylinder, whereby during the portion of the piston stroke occurring after arrest of the upper end of the linkage the lower end of the lever thrusts downward on the sub-rail.
Claim 10
Dependent Claim
71 words
A launcher according to claim 8, where the detachable connection means between the main launcher and the sub-rail is arranged such that the sub-rail slides rearwardly during the portion of the stroke of the piston-and-cylinder of the jettisoning means while the upper end of the linkage is sliding rearwardly which causes said connection means to detach from said launcher so that the sub-rail is clear to fall away from the launcher.
Claim 11
Dependent Claim
46 words
A launcher according to claim 9, further comprising co-operating inclined abutment faces on the sub-rail and the main launcher which come into mutual engagement at the limit of rearward sliding of the sub-rail thereby to cause a camming action imparting a downward thrust to the sub-rail.
Claim 12
Dependent Claim
57 words
An improved missile launcher of the type including a main launcher and a detachable sub-rail, the improvement comprising: a detachable connection member for detachably attaching the sub-rail to the main launcher, a jettison means for jettisoning the sub-rail from the launcher, and an actuator means for actuating the jettison means to detach the sub-rail from the launcher.
Claim 13
Dependent Claim
57 words
An improved missile launcher of the type including a main launcher and a detachable sub-rail, the improvement comprising: a detachable connection member for detachably attaching the sub-rail to the main launcher, a jettison means for jettisoning the sub-rail from the launcher, and an actuator means for actuating the jettison means to detach the sub-rail from the launcher.
Claim 14
Dependent Claim
44 words
An improved missile launcher according to claim 11 where said detachable connection means is a latch and said jettisoning means is arranged to slide the sub-rail longitudinally for disconnecting said latch and further including thrust means for imparting a downward thrust to the sub-rail.
Claim 15
Dependent Claim
62 words
A launcher according to claim 11 where the jettisoning means comprises a gas-operated piston-and-cylinder and the launcher further comprises a lever including an upper end and a lower end, a linkage upon which said jettison means acts, and an abutment on said sub-rail, whereupon actuation of said jettisoning means causes said lever to thrust first rearwardly and then downwardly on the sub-rail.
Claim 16
Dependent Claim
71 words
A launcher according to claim 13 where the detachable connection means between the main launcher and the sub-rail is arranged such that the sub-rail slides rearwardly during the portion of the stroke of the piston-and-cylinder of the jettisoning means while the upper end of the linkage is sliding rearwardly which causes said connection means to detach from said launcher so that the sub-rail is clear to fall away from the launcher.
