Claims priority, application Great Britain January 27, 1949 Claims. (Cl. 89-375) This invention concerns gun installations for vehicles, more particularly for aircraft, of the type in which the gun barrel lies along a blast tube carried by the vehicle and the gun is mounted on the vehicle independently of the blast tube.
The present invention has for its object to provide a gun installation of the type set forth in which the blast tube is readily removable to give access to the gun barrel, the gun is readily removable from the vehicle and the blast tube and gun are independently carried by the vehicle for movements relatively thereto and for movements relatively to each other. Another object is to reduce or prevent the passage of gases from the blast tube of the gun to inside the vehicle (or pilots cockpit).
According to the present invention a gun installation of the type set forth is characterised in that the seating member of a first spherical-seating joint is the ball member of a second sphericabseating joint, the seating member of the second joint being carried by the vehicle, in that the blast tube is carried by the ball member of the first joint and the gun by the ball member of the second joint and in that the seating member of both joints is in two parts which are separable to allow the ball members thereof to be removed, the blast tube and its ball member being removable lengthwise of the tube and the gun and its ball member being removable transversely of the gun.
Preferably the ball members of the first and second joints lie the one within the other and both are carried within the seating member of the second joint.
A practical application of this invention is shown in the accompanying drawings whereof:
Figures 1A and 1B together constitute a side elevation, partly in section, of a gun installation in an aeroplane in accordance with the invention,
Figure 2 is a sectional elevation to a larger size of a part of the installation of Figure l, and
Figure 3 is a section on the line 33 of Figure 2.
The gun, which is generally indicated by the reference numeral 5, lies, within the fuselage 6 of an aeroplane (not shown). The fuselage forms a supporting structure for the gun and blast tube mount. The, gun is carried by a gun housing 7 which is suspended from the spars 8 and a blast tube 9 extends forwardly from beneath the housing 7 and passes through an opening in the fuselage 6. The tube 9 projects through the fuselage to a small extent and is there covered by a fairing 10. The gun barrel 11 lies within the blast tube 9. j
The inner end of the blast tube 9 has a tubular extension 12, the outer surface of which is formed as a ball member 13 which is universally mounted in a ball and socket member 16 to provide a universal connection or joint 14 for the blast tube. The member 16 of this first joint is formed with an axial aperture within which the ball member 13 is disposed. The inner surface of the member 14 includes a semi-spherical portion 16 which seats one end portion of the member 14, and a diametrically reduced threaded portion 16*. A radial shoulder 31 is formed between the portions of the inner surface 2,7993% Patented June 7, 1955 and an externally threaded ring 15 is provided and has an inner part-spherical surface. The ring is screw threaded into the portion 16 in the lengthwise direction of the blast tube and forms a continuation of the semispherical portion 16, the ring forming a detachable means for retaining the ball member 13 in position. The ring 15 can abut against the shoulder 31 but it is preferred to provide a seal of heat-resisting material 17 against which the ring is screwed, the seal ensuring that gases in the blast tube may not pass through the first joint.
The member 16 of the joint 14 has an outer portion which is spherically formed and defines the ball member 18 of a second spherical-seating joint, generally indicated at 19, it being arranged that joint 14 lies within joint 19.
The ball member 13 is continuous in the circumferential direction and its seating member comprises two semi-circular abutting straps 2i and 21 which form a socket member or means. Shims 29 are provided between the straps so that they are spaced apart to a required extent. The two straps are drawn together by bolts 22 (Figure 3). The lower strap 21 is removable from the upper strap 20 which is permanently carried by the gun housing 7.
The member 18 has a tubular extension 23 which lies on the opposite side of the joints to the blast tube. A part 24 of the gun enters the extension 23 and is suitably secured therein by a ring 25 with the gun barrel passing through member 13 and extension 12 into the blast tube.
The gun is also supported by a rear mounting 26 having means 27, 28 for moving the gun so that its barrel 11 is relatively adjustable within the blast tube to a limited extent, the gun being moved about the joint 19. In this way the alignment of the gun may be adjusted.
With the construction described the ring 15 is easily removed whereupon the blast tube 9, extension 12 and member 13 may be withdrawn axially over the gun barrel. Access may then be had to the gun barrel. After removal of the blast tube, the strap 21 of joint 19 is also easily removed so that the gun may be lowered from housing 7the rear mounting 26 having been previously disconnected.
In use, the joints 14 and 19 allow relative movements between the blast tube and the fuselage, between the gun and the fuselage and between the blast tube and the gun.
Joint 14 is effectively sealed at 17 against the passage of gases from inside to outside the blast tube and thence to within the fuselage.
The ring is prevented from accidentally working loose by a locking key device 30.
