The' present .invention relatesI to exterior bomb containers whichare preferably carried exterorly beneath bombing aeroplanes, and usually-byfone point` oi'suspension-on a bomb rack mounted on the plane.

lAnlarrangement of parts is provided herein which'will operate `when it-is desired to dump or trip the Whole container'and its` contents as a unit. This. `feature is common to other vtypes oi 'bomb-containers in that the container is prefer,- ablyattached at a single point of suspension to a-,bomb ,rack-which is attached 'to the body of an aeroplane. v:Vi/Then ,it is desired to discharge the container as a Whole, mechanically operated Icables within reach of the aviatorcan be .used to` operate thebomb rack and immediately disengage the whole-,container and .its load of bombs from .the aeroplane.

,In some types ofy bomb containers the release ofthe bombsfthereinis accomplished by a mechanical, device Ywhich is usually. manually controlled.` and `operated from an operating device Wthinfeasy reach of the 4occupant of the areoplane. In other.y types ofA containers the bombs are-.released bya push-button or other electrical device also-Within easy reach ci the occupant of the .plane The present invention isy of the former or mechanically operated and" actuated type. The modus operandi of the present type of invention will-,befully explained in this specification.

.-The.presentybomb container comprises a metal shellzimuch :ina :the shape of a normally `closed cylinder.havingebullet-nosed front and rear ends, and.-;provided with two `pairs of swinging hinged doors mounted beneath the container. vOne of thefieatures of thepresentinvention is an arrangement of` partsvvhich` isdesignated thedoor locking 1 and releasing -mechanism, which -upon proper vactuation vretracts the locking latches whichy :normally hold the doors of the bomb containeriin closed .position within the exterior outline oi the .container in order to avoidwind resistanceas is at onceunderstood After the door latches: are :withdrawn as Will be described, the doorsfof the containerl are-iree-to drop open by gravitydue -to the load of bombs which they carry upon them.

'Assoonas all the bombs have been discharged fromthe. container'springs preferably located on the hinges 'of the doors act to close thesame, and theautomatic means provided on the ,doorV locking and releasing mechanism reverses the rst operation ofthe latter, andthe locking latches 2 are automatically replaced in r.eI-1g.glirilent..with the doors andl securely lock. them untilagain released by theaviator.` The details of .thisdoor locking and releasing mechanism w-ill .be-specifically explained at lengthhereinaften and is a one of iheirnajor' elements of thoinveniion- The Container .in y.nandfisndirided. internally into two compartments, rforwardand aft,and each compartment is larranged torelease allthe bombs Ycarried therein irrjone Vgroup or simultaneously.

The mechanical parts ofthe container in both 'compartmentsv I8, I9 are substanf l tially alike, asr will be seen 'as the specic descrip#- tion proceeds herein. l v

Asv the chambers I8, I9 are substantially alike,

sufce for both halves of the bomb container.

The interior arrangement of the container is readily understood from Figs. 3, 4, 5 of the drawings. The shell II`, has a horizontally disposed top division wall 2 I, and vertical division walls 22, 23, 24, 25, 26 all connected together, as shown in Fig. 3 and supported on the walls of container I. The doors I2, I3 are provided with horizontal parts 21, 28 properly supported by the subdivision walls 29, 30, 3I, 32, and those parts provide the closure for the container I, upon which rest the load of bombs such as 33, 34, etc. The bombs 33, 34, etc. as seen in Fig. 3 are piled in the chambers formed by the walls 22 to 25 inclusive. The compartments I8 and I9 each are provided with bungee cords which are resilient, each with two substantially perpendicular branches 35, 31, and a horizontal portion 38. Vertical walls 22-26 have slots 35a in which bungee cords 35 slide. The container I, is inverted when being loaded with bombs so the doors I2, I3 are on the top, and as the bombs 33, 34 are pla-ced in the chambers the bungee cord is placed in tension as is readily understood and seen from Fig. 3 clearly. It is also evident that when the doors I2, and I3 are unlatched from the locking latches, 39, 39a, Fig. 4 they will be operated upon by gravity, and swing downwardly on hinges I4, I5 Fig. 3, and take positions indicated at I6, I1; and all the bombs in the container are then at once dropped or discharged therefrom by gravity, as well as by the action on the bungee cord 35 on the top of the bombs, which cord being under tension tends to shorten itself, and thus insure the complete expulsion of all the bombs in the container. It will be seen that the locking latches 39, 39a,

The yhub 55 is rotatably mountedy on the vertical pintle 5l, which in turn is carriedin bearing 58, f

on the top of horizontal division wall 2| of the container, and in bearing 53 formed in a recess dll in the top-'most portionv of the metal'shell II ofthe container I- A lock-nut 6I secures the upper end of pintle 51 against play or movement,

and 'a cover plate 62 is used to coverthe said gpintle andflo-clr-nut as shown clearly in Figs. 3 and 4. f

the vdescription of the parts ofone chamber will L The cover-plate 152 is also usedas fa. bearing plate forv holdingthe bomb ,container in longitudinal alignment, in conjunction with the supporting device or hookv r625 which supports the containerat point Hl by means of the enclosing metal band 63, and its upstanding lugs 64, 64. The tooth or hook 65 is part of the bomb rack 3, which is a well known device and not a part of the present invention as before mentioned herein. From the bomb rack 9 also extends downwardly a vertically positioned holder 56 having a pair of opposed arms, 61, 61 which bear against the cover plate 52 with a reasonable amount of holding pressure but is not attached to the cover plate nor bomb container I at these points. It is of course apparent from Fig. 1 that there are two mechanical holding devices 66, forward and aft of the container, which cooperate with the central point of suspension devices at point I0.

The devices 1 and 8 each comprise two bent arms 68, 69, and a vertical portion '10, the latter being fastened to the aeroplane at points 1I 1I. In the devices 1 and 8 also are found rotatable vertical rods 12, 12 the upper end of which can be rotated by means of cable 5 by the aviator. The lower end of rod 12 is provided with a rigidly mounted outwardly extending bent arm 13. On the pintle 51 is rigidly mounted an outwardly extending and operating arm 14 on which is carried an upstanding pin 15, adapted to engage a U-shaped recess in the end of arm 13 but not positively, and only slidably engaged therewith. The inner end of arm 'I4 it is seen will revolve the hub 55 and with it the short levers 53 and operate connecting rod 52. The device 8 and lever 13 then can actuate the hub 55 and connecting rod 52. In case of a discharge of the whole bomb container it is quite evident as soon as the container is cut loose or freed from the plane at point I0 (Fig. 1) the arms 13 are slidably disengaged from pins 5 'I' and the *whole bomb rack' can be' dropped' as' auiiitffroxnthe-lplane;

v:Itisevident"froml Fig. 2 that when lever' arm "M"'i's-i'riovedic'lbck'w'ise,y connecting. rod' 52a, latch-v lever 'affandflatch 39a will be'operated, and" the latter .retracted -andriree'd from the part 46a. And by thef's'ame actuationof'leve'vam T4 andsimubtaneoslytherewith the'connectin'girod 52; latch-'- lever' '43" and'lat'ch' 3'9" willl be operatedl andthe latter r'e'tract'edfand freed from the'part 46'. Both these'v latches' 39 and 3%: being thusA retracted the doors It" and' It' areacted uponK by" gr'avity andv drop open; Yand discharge all` the bombs in compartment' I8.

"With" regard` toltheoperation of the latch t9, it is clear from what has beensaid't-hatas soon asconnectingr'od 52 is operated towards'th'e left (Fig. 2);-'b'yvthe aviator,-that bent latch-levers fii'arfe thrown-tothe rightfor'n a'retracting direction at their lower ends,` with reference to latches 3dr-andthe doors I 2,: yI-S'are free tofall by gravity and the` load ofbornbs completely discharged from-- the bombJ container.

Itfrisnoted` that spring "lo on' rod 52 yis compressed by thef actions just-described. v InA connection rwith the connecting rods 52, itfisevidentfthe spring To (which abuts against adjustablecollar- Il 'ont-he rod 52,'-and al-so a'buts against anglev*Iii-carried onthe angle 'ItA of the container framework) will automatically actuatethe'rod .'ihtoward the right as seen in the* rig-ht side of- Figi 2- after an unl-atching-operation hasfbeenperformed-by theaviator. As soon'as thefconnecti-ngqrod' 52de moved to the right-the top othelatch-lever tv at point 5I- also -movestof theright'as seen from Fig-4f, and the bottom ofgsaid latch-lever moves in theoppositedirec;v tion since the lever is pivoted onf-fulcrum 41. Thisaction throw-s thelatch- 39` into engagement withthe part llii.4 (if the doors I2 and I3 in the meantime have-been lifted' toa closed position) and-locksfsaid'doors sogthey are within the outline ofthe bomb containerysince thisis--importa'nldue -to the 'high rate of speed1 ofy theaeroplane as is at once understood. Y

The-.method ci raising the doors I2, I3 from their opened positions I5, Il respectively, to closed positions will bedescribed below.

yIn the above casewe see that it was the device l, Fig. l", which openedforward compartment I8 of the container I. It isv also equally evident that vthe device' 8; Fig. 1;'will'operate to open aft compartment I9 of said container.

If ga second cable similar to cable 5 is used' tov op'ei'atefdevice', 'and cable -5 is used only vio'r device' l, 'itis clear that thev bombs in compartments' I8 and i9"mfay` be'disch'arged 'in sequence, or in simultaneous order, or one compartment may be used and the other withheld or reserved to any desired later time for discharge purposes.

If the two devices 'I and 8 are connected by a rod 5a or if cable 5 is attached to device 8 and also to device 1, it is evident all the bombs in both compartments may be simultaneously discharged. Or if it is desired to drop the whole container and bombs therein, it is evident the cable 6 can accomplish this by the use of the bomb rack 9 and the connection at point IIJ, Fig. 1.

It is believed hardly necessary from what has been said to further explain the similarity of the parts in the two compartments I8 and I9, of container I.

In connection with the raising of the doors l2, I3 from positions I6, I'I respectively shown in Operation .Assuming that the container i' has been 'loaded with bombs' and rioun'tedv onthebombrack', Fig. l', afd the aviator is 'ready 'to drop the 'bombs from' Compartment I8 of the' oonl'jarier; the 1anya'rd or cable 5 is operated'whichoperates device 8,1 and? itsu bent. lever` arm" 13;. and thev operating arm 1741 This' operatesthe'two latch-levers 43, anc'sz., andlat'ches-sef andsea; Fig. 4, and releases doors I2` and I'S.- YThe'wei'ght of the pluralityofy thelibornbs overcomes' springs Sil, Sllthe' bungee cord '35 a'ssistslinthis operatiomend' the load of vbombs-drop 'romfsaid compartment'- I8.
