BOMB-CARRYING am @man UNDER THE Ac'r oF Manen 3, 188e, 22 STAT. L., 625.)

To all whom t may concern:

in the United States, without payment of any royalty thereon.

This invention relates to a bomb carrying gear for airplane bombs.

It is an important object of this invention to provide a simple, strong and light carrying gear for bombs so designed that the bomb is hung from a point above and `to one side of a bearing .for the sidevof the bomb, whereby the weight of the bomb will cause the side thereof to bear against the bearing and so prevent any vibration of the bomb whilethe airplane is in flight. The above faces in oppositedirections and so balancel described arrangement does not in any way interfere with the release of the bomb.

It is a further object of this invention to provide a mainsupporting rib on which two bombs may be hung and four bearing surfaces forthe sides of the bombs, two of said surfaces being located below and to one side with -respect to said rib, the other two of said surfaces being located below and on the op-v posite side with. respect to the said rib, whereby the sides of the bombs, due to their own weight, bear against said bearing sureach other.

It is a further object of this invention to provide a truss support for the said bearing surfaces.

It is a further object of this invention to provide a supporting rib on which two bombs may be hung and which is shaped substantially like an inverted V. The bombs are so hung with relation to this rib that the pull due tothe weight of the bombs is substantially parallel to the respective legs of said inverted V-shaped rib. This gives an extremely sti and rigid support, with a minimum of weight. l

Other objects and advantages will appear as the description proceeds.

Fig. 2 is an end view of the same.

Fig. 3 is a section on the line 3-3 of Fig. 2.

` Fig. 4 is a view partly in section of the releasing mechanism.

Figs. 5 and 6 are sectional views of the releasing mechanism, showing successive stages of operation.

Fig. 7 is a perspective view ofthe sup- `porting rib and associated parts.

F1g. 8 is a section of the same taken on the line 8-8 of Fig. 3.

Fig. 9. is a section of the same taken on the line 9 9 of Fig. 3.

The bomb carrying gear comprises a pair of horizontally extending supports, extending transversely with respect to the path of the airplane. These supports are substantially parallel to one another, the forward one being indicated at l and the rear one at 2.

Thesevsupports are stream lined to minimize air resistance.

The supports l and 2 are supported from beams 3, suitably attached to the body or plane 4 of the airplane.

A pair of substantially U-shaped brackets i 5 and 6 supported by bolts 7 from the front support l inclose between them the end of the main supporting rib 8, which is shaped like an inverted V. The rear end of the rib 8 is supported from the support 2 by precisely similar means. The brackets 5 and 6 and the end of the rib 8 are bonded together by being dip brazed.

A pair vof arcuately shaped hangers 9 and l0 are positioned in suitalble apertures through each ofthe legs of the rib 8 and are rigidly held inposition by cotter pins 11, and by dip brazing. The

parts

5, 6 and 9 may be dip brazed by the same operation.

The rib 8 is provided with a pair of longi-l tuating plate 13, provided with an outwardly bent trigger engaging end 14, is attached to a second sliding plate 15, the two plates being connected together by lugs 14, said lugs passing through the slot 12 and being formed as a part of the plate 15, and held in engagement rwith slide 13 by cotter pins. Each of' the slides 15 has attached thereto a spring 16, the other end is attached to a pin 17 fastened to the rib 8, to keep the slides 13 and l5 to the right, as shown in Fig. l. Each of the slides 15 has attached at its other end an actuating rod 18, controlled by levers 19 and 20, which in turn are controlled by manual operating means, not shown.

The front bearin for the bomb will now be described. Thisgbearing comprises vertically disposed bearing

surfaces

21 and 22 preferably made integral with a connecting piece 23. These bearing surfaces are sup' ported bya, V shaped element 24, which is attached to the support 1 by bolts 25, and which, at its apex is attached to the connecting piece 23. A compression element 26 is positioned between the apex of the V shaped element 24 and the support 1 to complete the truss support for the bearing surfaces. An additional brace 27, engages with the

bearing surfaces

21 and 22. A precisely similar set of bearing surfaces and supporting truss are provided toward the rear end of the bomb carrying gear, a's shown in Fig. 1. |The two trusses may be braced apart by the element 28.

It should be noted that the bearing surfaces 21 and 22 are located below and to one side with respect tothe rib 8.

The means, for attaching the bomb to the rib 8 will now be described. This connecting means or hanger comprises an elongated body element 29, made by bending a sheet of metal into substantially U-shaped form, the bight of the Uibeing indicated at 30.

The metal forming the ends of the element 29 has its upper parts fastened together as indicated at 31 and 32. Apertures 33 and 34 are punched through the respective-

portions

31 and 32. It should be noted that these said apertures are spaced unequally from the ends of the element 29.`

These said apertures are adapted to engage over the ends of the

arcuate elements

9 and 10. It should be noted that the

arcuate elements

9 and 10 are also correspondingly and unequally spaced from the respective ends of the ri=b 8, being so arranged however that if the element 29 is engaged with the

arcuate elements

9 and 10 right side up, the apertures 33 and 3.4 will properly t over said

elements

9 and 10, but ifelement 29 is attemptedto be engaged on

elements

9 and 10 wrong end to the said apertures will not engage over said

elements

9 and 10, and so the improper mounting of the ele- 43 attached to the bomb. It rwill be apparent that the heavy weight of the bomb acting on the lever hooks 35 and 36, will tend to move the up er arms of said hooks to the left, and wil consequently tend to move bar 4l y to the left.

A locking sear 44 is pivoted to the bar 41 at 45 and is normally urged downwardly by spring 46 bearing against itl and against an upper edge of the bar 41. The sear 44 is provided with a shoulder 47 that normally is engaged over an edge of a stop 48 rigidly mounted to the hanger 29. When the parts are engaged as in Fig. 4 it is apparent that the bombs will be effectively held against release.

A trigger 49 is pivoted to the hanger 29 at 50, is provided with a cam face 51 that bears against the lower edge of the sear 44, and is further provided with a notch 52, which overhangs the end 53 of the sear 44 and acts as a safety catch in case of failure of spring 46. The trigger 49 is urged to the left by a spring 54. The described parts are so proportioned and shaped that when the trigger 49 is moved to the right, notchf 52 is first moved from the path of the end 53 of the sear, after which the cam surface 51 lifts the sear 44 from engagement with the stop 48, whereupon the bar 41 is released and moves to the left to release the bomb,

a sequence of operation clearly shown in Figs. 5 and .6.

The trigger 49 is actuated through the already described lever 20, rod 18, slide 14 and lug 15, Figs. 1 and 3, or it may be actuated by a wire or cable fastened thereto in the aperture 49.

It should be understood that each rib 8 carries two hangers 29, as shown in Fig. 2

and so supports two bombs.

The hanger 29 and associated release mechanism forms the subject of a separate application, Serial No. 302,585, filed June 7,
