BOMB nAoK.

Application filed. August 7, 1823. Serial No. 656,199.

prove and strengthen the construction of the supporting beams for bomb shackles and remove the cause of failure and accidental release of bombs. This has become of great importance on account of the fact that bombs of greater and greater weight are being constantly designed for use in warfare.

\Vith the above and other objects in view, th invention consists in the novel construction, combination and arrangement herein shown, described and claimed.

In the accompanying drawings.

Figure 1 is a front elevation of a bomb rack embodying the present invention.

Figure 2 is a side elevation thereof.

The present improvement relates to a bomb rack designed in such a way that the load of the bomb is suspended from the release mechanism C which is attached to the supporting girder D. The girder I) is carried by two bomb shackle supporting beams X each of which is maintained upon the airplane by fittings at the points B, B.

In the construction of each of the beams X, I employ a compression member 1 in the form of a plate and a tension member 2 also in the form of a plate, said plates being of any suitable length and width according to the weight to be imposed thereon. Between the members 1 and 2 there are interposed torsion members 3 and 4 each shown in the form of a channel beam, the parallel flanges of which abut against the adjacent faces of the members 1 and 2.

Enclosing the members 1, 2, 3 and 4 is a streamline housing 5 usually formed of sheet duralumin, the upper and lower portions of which, bear against the outer faces of the members 1 and 2. Through bolts 6 extend through the members 1 and 2 and through the flanges of the members 3 and 1, also through the upper and lower parts of the streamline fairing 5, and also through the clips or fittings 7 connected to the opposite end portions of the beams X and also through the base fiangeS of the stabilizing members E which serve to steady the bomb, the outline of which is indicated at F. The weight of the bomb carried by each beam is divided so that some of this weight is taken by the streamline fairing andsome of it is taken by the aforesaid tension, com pression and torsion members.

As a result of the construction and arrangementabove described, the initial strength of the structure is higher for the same size and weight of bomb, no deterioration is experienced due to the effects of moisture, heat and other atmospheric c-onditions, exact strength may be more easily duplicated than in the case of a wooden beam, as the wood varies greatly in strength due to treatment before being worked. The strength of the mounting stations is higher, or in other words, in using wooden beams extreme care must be exercised at the mounting points to prevent the fiber of the material from being broken down. This might be caused by tightening the bolts which are used to mount the brackets too tightly or by tilting the brackets as they are drawn down. The safety factor of the improved beam is at all times apparent, that is, the approximate condition thereof may be observed from the outside of the structure. In the case of a wooden beam this is impossible as the beam may be apparently all right as far as can be seen from the outside but may have deteriorated to a great extent under the surface. This advantage facilitates inspection of the racks while on the airplane.

I claim:

1. In a bomb rack, a. bomb shackle-supporting beam consisting of a metallic compression member, a metallic tension member, and parallel metallic torsion members interposed between and united to said. compression, tension members and a metallic streamlined fairing enclosing the aforesaid beam members and means for securing the fairing to said beam.

In a bomb rack, a bomb shackle-supporting beam consisting of a metallic plate like compression member, a metallic plate like tension member, two channeled torsion members interposed between said compres sion and tension members, a metallic stream lined fairing enclosing the aforesaid members and dividing the weight of the bomb with the said members, and a plurality of bolts interconnecting said members and said fairing.

3. In a bomb rack, the combination of a beam formed of metallic compression and tension members and metallic torsion members located between the compression and tension members; a streamlined fairing for the beam; a bomb supporting girder supported by said beam; stabilizers for the bomb; and through bolts for'sec'uring the stabilizers and the fairing to the said beam.

4. In a bomb rack, the combination of a beam formed of metallic compression and ,tGllSlOIl members, and metallic torsion members' located therebetween; a stream lined fairing for the beam; fittings above the beam for engagement with a support; and through bolts for securing the beam, fairing and fittings together.

In testimony whereof I afiix my signature.
