(c1. v16a- 2) 6 Claims.
This invention relates to a fire extinguishing system especially designed for use in extinguishing airplane engine res.
One of the principal objects of my invention is the provision of means for preventing the es-y cape of fire extinguishing fluid discharged into the engine hood so as to effectively extinguish engine nres and in a much shorter period of time than heretofore possible.
One of the specic objects of this invention is the provision of means whereby fire extinguishing fluid may be discharged into the engine housing n and its escape therefrom prevented by the'cper- Yation of a single manipulative means.
,. the following description taken in connection with the drawings, in Which- Fig. 1 is a top plan view, partly broken away, showing my invention carried out in connection with a ring type closing member;
Fig. 2 is a side view, partly broken away, mechanism disclosed in Fig. 1;
Fig. 3 is a top view, partly broken away, showing my invention carried out in connection with a flap type closing mechanism; and
Fig. 4 is a detail of the nap type closing mechanism.
In the drawings, the fuselage is generally indicated by the reference character 5. The instrument board is shown at 6, the engine at 1, and the engine compartment at 8, thefengine hood being indicated at 9.
A high pressure liuid container I may be supported as indicated in the various figures between the engine compartment 8 and the instrument board 6. This container may beiprovided with .any suitable form of discharge head II which may be operated through a rod I2 by means of a handle I3 suitably mounted on the instrument board E. Located to the rear of the engine 'l is a distributing discharge ring I5 provided with discharge orifices or nozzles I6 as indicated. This discharge ring is connected by a tubing I1 to the discharge head Il.
As disclosed in Figs. 1 and 2 I may provide a sliding closing ring 20 slidably supported on the outer wall of the engine compartment. Theforward end o'f the closing ring- 20 is provided with an inturned ilange 2| preferably of the shape disclosed which when the ring is moved from the full line position shown in these gures to the dotted line position shown in Fig. 1' will close the opening or slots 22 at the rear end of the engine hood usually provided for the escape of thev cooling air. f
As disclosed in these Figs. 1 and 2 a suitable number of cylinders 25 may be suitably supported on the outer wall of the engine compartment and their pistons 26 may be provided with right angular extensions 21 which extend through slots 28 in the outer wall of the engine compartment and are connected to the closing ring 20. I have provided means for utilizing the fluid discharged from the container .I0 for operating the pistons in the cylinders. This means consists of a' tube 29 connected to the tubing I1 near the discharge head and to a distributing ring 30 connected to each of the cylinders 25.
When the operating handle I3 is pulled, fluid is discharged from the container I0 into the engine hood 9 to extinguish the engine fire and into the cylinders 25 to move the closing ring into sealing position at substantially the same time. This prevents the escape of uid through the cooling air escape opening or slots 22 at the rear end of the engine hood 9 and coniines the fire extinguishing fluid therein.
In Figs. 3 and 4I have disclosed my invention as applied to a ap type closing means in which the cooling airescape opening or slots at the rear end of the engine hood 9 is closed by. means v of a circular series of flaps which are pivotally supported on the front transverse wall 4I of the engine compartment. These naps are operated by pistons 42 in the operating cylinders 25 when fluid is discharged into the engine hood by means such as disclosed in Figs. l and 2. As the fluid is discharged the flaps 4U are moved from the full line position disclosed in these figures to the dotted line position shown in Fig. 4 to close the cooling air escape opening or slots at the rear .end of the engine hood 9 so as to prevent the escape of the .nre extinguishing uid discharged therein.
While for the purpose of disclosure, I have'v shown and described specific embodiments of my invention, it is to be understood I reserve the right to all such changes as fall within the prinf ciples of my invention and the scope of the appended claims.
I claim:
1. In a re extinguishing system for extinguishing engine fires, in combination with an engine hood provided with a cooling air escape opening at the rear end of said engine hood, means for closing said opening, a container for fire extinguishing fluid, and a manipulative means for discharging fluid from said container into said hood and for operating said means for closing said opening.
2. In a flre extinguishing system yfor extinguishing engine flres, in combination with an engine hood provided with a cooling air opening, pivoted flaps adapted to be moved to close said opening, fluid operated means for moving said flaps, a container for re extinguishing fluidIl a discharge tube leading from said container into said engine hood and to said fluid operated means, and a manipulative means for releasing fluid from said container into said discharge tube.
3. In a fire extinguishing system for extinguishing engine fires, in combination with an engine hood providedwith a cooling air opening, a ring movably mounted to be moved into position to close said opening, fluid operated means for moving said ring, a container for fire extinguishing fluid, a discharge tube leading from said container into said engine hood and to said fluid operated means and manipulative means for releasing fluid from said container .into said discharge tube.
4. In a flre extinguishing system for extinguishing engine res, in combination with4 an engine hood provided with a cooling air opening, means for closing said opening, a container for fire extinguishing fluid, a uid distributing device Within said engine hood, a discharge tube leading from said container to said device, means for releasing fluid from said container into said discharge tube, fluid operated means connected to said closing means for moving said closing means into closed position and a tube connecting said discharge tube to said fluid operated means.
5. In a re extinguishing system for extinguishing engine flres, in combination with an engine hood provided with a cooling air opening, pivoted flaps for closing said opening, a container for fire extinguishing fluid, a fluid distributing device within said engine hood, a discharge tube leading from said container to said device, means for releasing fluid from said container into said discharge tube, a plurality of fluid operated cylinders one for each of said flaps, the piston of each cylinder being connected to the adjacent flap to move the same into closing position, a fluid connection between said discharge tube and each cylinder and means for-operating said releasing means for releasing fluid from the container through said discharge tube into said hood and into said cylinders.
6. In a fire extinguisher for extinguishing engine res, in combination with an engine hood provided with a cooling air escape opening at its rear edge, a ring for closing said opening. a plurality of cylinders provided with pistons connected to said ring, a re extinguishing fluid distributing device located in said engine hood, a container for fire extinguishing fluid, conduit connections between said container and said cylinders and said fluid distributing device and means for releasing fire extinguishing fluid from said container.
