Abstract

Abstract A rocket launcher having a magazine chamber which houses a loading tray which terminates into a launcher tube. A conveyor roller for feeding the rockets laterally into the loading tray. An apertured closure member having a backscattering surface for the emerging rocket propelling gases and an apron member which acts as a further backscattering surface for the chamber arranged on the magazine chamber. In this way the torques which are exerted, in operation, on the magazine chamber and which are caused by the pressure of the rocket propelling gases on the two backscattering surfaces are of substantially equal size and are directed in opposite directions. The apron member forms a part of a flap member, which can be swung out under the pressure of the escaping rocket propelling gases.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 99 words
A rocket launcher, comprising a launcher tube, a magazine chamber, a loading tray in said chamber terminating into said launcher tube, a conveyor roller for feeding rockets laterally into said loading tray, and an apertured closure member for said chamber comprising a backscattering surface for the emerging rocket propelling gases, an apron member acting as a further backscattering surface for said chamber arranged on said chamber whereby the torques exerted, in operation, on said chamber caused by the pressure of the rocket propelling gases on said two backscattering surfaces are of substantially equal size and directed in opposite directions.
Claim 2
Dependent Claim 99 words
A rocket launcher, comprising a launcher tube, a magazine chamber, a loading tray in said chamber terminating into said launcher tube, a conveyor roller for feeding rockets laterally into said loading tray, and an apertured closure member for said chamber comprising a backscattering surface for the emerging rocket propelling gases, an apron member acting as a further backscattering surface for said chamber arranged on said chamber whereby the torques exerted, in operation, on said chamber caused by the pressure of the rocket propelling gases on said two backscattering surfaces are of substantially equal size and directed in opposite directions.
Claim 3
Dependent Claim 21 words
A rocket launcher as claimed in claim 1, wherein said apron member provides an outwardly bounding surface for the magazine chamber.
Claim 4
Dependent Claim 34 words
A rocket launcher as claimed in claim 1 wherein said apron member comprises a part of a pivoted flap member, which can be swung out under the pressure of the escaping rocket propelling gases.
Claim 5
Dependent Claim 43 words
A rocket launcher as claimed in claim 3, in which said closure member is pivoted on a spindle fastened to said magazine chamber and said flap member is pivotally mounted on a shaft extending parallel to said spindle and fastened to said chamber.
Claim 6
Dependent Claim 46 words
A rocket launcher as claimed in claim 3 wherein said flap member has a cam which, when said flap member is swung outwardly of the launcher, engages into a locking arrangement and where the release of said flap member is effected by a hand-operated unlocking device.
