BOMB-DROPPING DEVICE.

Specification of Letters Patent.

Application filed October 17, 1917. Serial No. 197,038.

To all whom it may concern Be it known that I, JOHN H. BARR, a o1t1- zen of the United States, and resident of the borough of Manhattan, city of New York, 1n the county of New York and State of New York, have invented certain new and useful Improvements in BOmb-DIODDIIIg Devices, of which the following is a speclfication.

My present invention relates to means for dropping or discharging bombs or othermissiles, and its principal object is to provide a oontrivance or apparatus embodying new and improved means of the character specified.

To the above and other ends which will hereinafter appear, my invention consists in the features of construction, combinations of devices andarrangements of parts hereinafter described and particularly pointed out in the claims.

In carrying out my invention in the present instance, I provide a magazine, receptacle or holder for a plurality of bombs or missiles, ten, for example, which magazine or holder is adapted to be carried by an aeroplane or other air-craft and to be operated therefrom during flights. My invention provides means for holding the bombs locked securely in the magazine so that accidental dropping or discharging is prevented, said means comprising preferably grippers or clamping jaws which cooperate with the neck of the bomb andare positively maintained locked in engagement with the bomb-by a controller. which is actuated by a handle or hand lever to positively swing the clamping jaws so as to release the bomb. The controllers are selectively operated so that the bombs may be released in predetermined succession by actuations of the handle butneans are also provided for so actuating the controllers that at a single movement of the handle any desired number of so that they will not explode on striking, as may be desired in some circumstances. Other improvements and advantages will appear in the course of the following specification.

The accompanying drawings illustrate the preferred form of my invention, only so much of the magazine and bombs being disclosed, however, as is necessary to a complete understanding of the invention. For military reasons it is preferred not to make a fuller disclosure of the bombs themselves in the present case, said bombs per so not being of my invention.

Figs. 14 and 15 are fragmentary perspective views showing the hand lever or handle and associate parts, the views being taken from opposite sides.

Fig. 16 is a fragmentary elevation of the' lower end of the hand lever member.

Referring first to the general views, Figs. 1 to 4, the magazine, container or holder for the missiles or bombs comprises a rec-' tangular body portion 1 which may be of sheet metal, and a cover .or top plate 2. The magazine shown is of a size adapted to contain ten T. N. T. bombs weighing twentyfive pounds each, said bombs being arranged in two rows of five bombs each. The clamping jaws and controllers are correspondingly magazine at or near its bottom, said ledgebeing made preferably of light angle iron and providing stock to which may be fastened struts or other devices that secure the magazine to the aeroplane or other support or carrying device. Referring to the bombs as they are arranged in the magazine,

each one is provided at its upper end with a head or nose portion 4 which is joined to the body portion by a neck 5. The end portion or neck extends upward through a ciropening being provided at one side with a narrow extension 6. A wire safety device 7, carried by the bomb also extends upward through the hole 6, being accommodated by the narrow end portion 6 thereof. Anupwardly extending portion 8 of sa d wire terminates in a cross portion which is adapted for cooperation with a hook or stripping bar, as hereinafter explained. Somewhat below the neck the wire 7 is looped into a groove 9 in the body of the bomb, the looped portion or chp extending somewhat more than half-way around the bomb and providing a disconnectible spring connection between it and the wire 7. Thence the wire extends downward to the lower end of the bomb where it engages with one of the vanes or blades of a wheel, propeller or rotary device, or other arming device, which is included in the means for controlling the cob rating firing or detonating devices or the bomb. These devices, which as has been stated are preferably not herein disclosed, are

normally separated so that they can not cooperate to fire the bomb until the rotary device is rotated to permit bringing them in juxtaposition. It will be understood that when the bomb is discharged and the wire 7 stripped from it, as hereinafter explained, the bomb under the force of gravity will drop through a trap door in the bottom of the magazine and turn over so that the nose is at its lower end, and as it descends the rotary device will rotate, releasing one of the detonating devices into position to cooperate with the other when the nose strikes. If, however, the wire is not stripped but remains on the bomb, then the detonating devices remain locked in safety condition; or so far separated that even' when the nose strikes the bomb will not be discharged.

The top plate 2 is provided at its under side with a downwardly extending rectangular rib 10 which fits into the upper end of the magazine 1 and is suitably secured thereto. The under side of the top plate is also provided with a central longitudinal rib 11., which tapers somewhat from the ends to the middle and from which branch out a number of lateral ribs 12 that connect it with the outer rib 10. Thus in effect the top plate comprises a grid and a connecting web portion. Around the holes or bomb openings 6 the top plate is provided with a thickened finishing face or boss 13. This thickened portion, except in the case of the two righthand end holes, extends entirely around the j holes except at their left-hand sides. the case of the two end holes aforesaid the thickened portions 13 do not extend around the portions 6 of the holes. Additional bosses or thickened portions 13 are provided on the top plate near its left-hand end.

Each bomb is prm'ided with separate and independent holding means for holding it in pers are arranged in parallelism at opposite I sides of the associate bomb opening, each gripper comprising a shank 15 and a wider end portion or jaw proper 16, the inner face of which is so curved or shaped, as indicated at 17, as to cooperate properly when operated with the neck portion of the bomb and so that when the grippers are swung apart to release the bomb they will do so at all points substantially simultaneously. This will be better understood from a consideration of Fig. 6, which shows a pair of grippers open, the head 4 of the bomb being indicated by a dotted circle. It will be seen that each face or edge 17 is so shaped near the same instant. At theopposite end from the jaw portion 16, each shank 15 is provided with a hole which receives a headed shoulder screw 18 that serves as a pivot for the gripping arm 14. The pivot screw 18 passes down through an opening in one of the thickened portions 13 of the top plate and at its lower end below the top plate receives a washer 19 and a clamping nut 20 by which the pivot screw is firmly clamped in place, its upper shouldered portion resting on the upper surface of the thickened portion 13. The construction permits the gripping arm to swing freely on its pivot, said arm being loosely confined between the head of the screw 18 and the upper face of the thickened portion 13. Each gripper rests on and is adapted to slide over the adjacent thickened portions 13, as will be understood from Fig. 1. In the case of the two left-hand grippers, their pivot ends are supported on the bosses or thickened portions 13.

The grippers are adapted to be operated by means which positively control their swinging movements, both away from and toward each other, said means comprising a plurality, ten in the present instance, of controllers or cam members, there being one controller for each pair of grippers. The construction of the controllers will be best understood from an examination of the general views, Figs. 1 to 4, and in detail vlews, Figs. 5' to 8. Each controller, designated as a wholeby the reference numeral 21, comprises a stem 22, a cross bar 23, end blocks 24, and a top plate 25. The stem 1s formed at one end with diverging cam faces 26, terminating in noses or rounded portions 27. The cross bar 23 at its ends supports the end blocks 24, saidend blocks being provided with downward projectlons 28 which may be spread or upset slightly to hold the bearing blocks in place. The cover plate 25 is generally triangular in shape and is secured to the stem 22 by rivets 29, one of these rivets passing down through the cross bar 23 and securing it directly to the stem 22. Upward projections 30 on the end blocks pass through holes in the cover plate and may be upset slightly to secure the parts together. The end blocks are rectangular in shape. The projections 28 and 30 are round but are flattened on one side (D-shape) so as to prevent the end blocks from turning. The controller is arranged between the shanks of the associate pair of grippers, that is, the body portion or stem 22 is arranged between said shanks which pass through the space or passageway designated as 31. This space or opening 31 affords passage for one of the grippers, which is thus loosely confined between the end block and the stem at the sides while above and below the gripper is confined between the cross bar 23 and the cover plate 25. The

controllers 21 are slidably supported on the op plate 2, taking direct bearing on the thickened portions 13. The cross bars 23 which are below the surface of their stems 22 slide freely in the spaces, indicated at 13 (Fig. 7) between the portions 13. The end blocks 24 of each controller are loosely confined between two lugs or guides 32 rising from the top plate 2, these lugs preventing sidewise displacement of the controller and confining it to rectilinear movement. The controllers are normally locked against sliding movement by plungers or locking pins 33 which project upward through holes 34 in the stems 22. The plungers take bearings in depressions or seats 35 formed in lugs 36 which project downward from the under side of the top plate, these lugs being preferably extensions or enlargements of certain of the top plate ribs. Each plunger 33 is provided with a stem 37 which extends downward through the bottom of the lug 36 and terminates below said lug in a head 38. A coiled plunger spring 39. confined between the plunger proper and the bottom of the depression or socket 35, tends constantly to press the plunger upward, this upward movement being limited by the contact of the head 38 with the lug 36. In its uppermost position the plunger, as clearly illustrated in Fig. 7, projects partly through the hole 34 in the controller and positively locks it against sliding movement back and forth. Since the lugs 32 positively prevent movement of the controller laterally or at right angles to its sliding movement, it will be seen that the controller is thus positively locked against any movement whatever. lVhen thus locked the controller positively locks the grippers against effective rotary movement. This is due to the fact that the inner faces of the end blocks 24 at this time contactively engage with parallel edge portions 40 of the shanks 15 while the diverging faces 26 at the same time are contiguous to c0rresp0ndingl v diverging faces 41 on the inner sides of the shanks 15. Thus movement of the grippers either away from or toward each other is prevented. As hereinafter explained, the controllers are adapted to be separately unlocked and slid endwise toward the pivots ofthe grippers, bringing them to position such as is illustrated at the right in Fig. 6. During this sliding movement the cam faces 26 operate on the faces 4.1 of the grippers to swing them outward, this movement being permitted by reason of the fact that the inner faces of the blocks 24 have moved out of contact with the edges 40. On the return movement of the controller from left to right the inner corners of the blocks 24, acting on the inclined faces 42 of thegrippers, will swing them inward, the cam to permit of such a movement. The inward swing of the grippers toward each other 18 limited by a contact of the nose portions 16 in which the outer ends of the jaws 16 ter-- minate. At the end of the right-hand movement of the controller the noses 27 are seated in the rounded openings formed by the junction of the faces 41 with the aw portions 16 of' the grippers. ItWlll be understood that during swinging movements of the grippers toward and away from each other they remain positively controlled by the controllers by reason of the fact that the shanks 15 are at all times closely confined between the blocks 24 and the cam faces 26. Throughout the swinging movements the faces 42 remain in contactive engagement with the inner corners of the blocks 24, while the edges or faces 41 remain in contactive engagement with the cam faces 26. The result is that any possibility of loss of control of the grippers or clamping jaws is avoided. It will be understood that the controllers are arranged in two parallel rows or lines, each row containing five controllers and that the locking pins or plungers 33 are arranged in two parallel lines, each line containin five locking pins.

Means are provided or selectively displacing the locking pins 33 or moving them downward out of engagement with the controllers and associate means are provided for moving the controllers after they have been unlocked so as to cause them to swing the grippers outward to release the bombs. These means are so related that the controllers may be unlocked and operatively moved to effect a release of the bombs one at a time, or, if preferred, the controllers may be released from their locking pins one at a time to any desired number and subsequently simultaneously caused to operate to effect releasing movements of the grippers so that a selected or predetermined number of bombs may be simultaneously dropped. Generally described, the means aforesaid comprise two rows or sets of releasing pins corresponding to the locking pins, each row mounted on a carrier, there being two parallel carriers, said carriers also supporting devices or releasing members for effecting operative movements of the releasing pins in selected order, the releasing pins having the further function of connecting the controllers with the. carriers so that subsequent movements of the carriers may effect 0 erative movements of the controllers. here are two releasing members, one for each row of releasing pins, said members being controlled by a hand lever in such a way that they may be moved step by step independently of said carriers, so that any desired number of controllers may be released prior to being operatively moved. The carriers and the releasing members are all under the control of a single operating handle or hand lever.

The carriers aforesaid are in the form of channel bars and are illustrated in Figs. 1

to 4, 9, 1 0 and 13. Fig. 9 shows a channel bar that is at the rear, when viewed as in Fig. 1, while Fig. 10 shows the front channel bar of Fi 1. These channel bars, respectively designated as a whole by the reference numerals 43 and 44, correspond in construction but are rights and lefts, bein arranged lengthwise of the top plate an having their corresponding portions extending away from each other. With this understanding it will only be necessary to describe in detail one of the channel bars, preferably the forward channel bar 44 since it is the more clearly illustrated in detail. The channel bar 44 comprises a vertically arranged body portion 45, from the top of which projects forward, or toward .the ob server, as viewed in Figs. 4 and l0, a hori- 'zontally arranged ledge or lip 46. From the lower edge of the body portion near either end project two' short horizontal ledges or lips 47, these being sections, in effect, 'of a lower lip corresponding to the upper lip 46. At either side of the lefthand lip 47 the body portion projects downward, forming two vertical faces 48" and 48 which act as stops, as explained later. Projecting downward from the body ortion 45 at intervals are a number of angu ar fingers 49, these fingers terminating in forwardly projecting horizontal rounded portions 49. In the present instance there are five of these fingers, one near the left-hand end of the channel bar and theothers arranged at regular intervals along it. The horizontal. portions 49 are formed with holes 50 and in register with these holes are corresponding holes 5.1 in the ledge 46, each registering pair of holes providlng bearings for one of a set of releasing pins, subsequently to be described. Near its left-hand end the channel bar 44 is rovided with a cutawa or notch, indicate at 52, part of this notc being in the ledge 46 and part in the body portion 45. To the left of the notch a stop block or abutment 53 is secured to the top channel bar in any suitable way as b rivets. Somewhat to the right of the notc 52 an upright finger 54, formed at its upper end with a hole, indicated at 54, is secured to the rear face of the body ortion 45 in vany suitable wag, as by rivetlng. Just to the left of the nger or standard 54 a notch 55 is cut in the channel bar, this notch or slot 55 being similar to the notch or slot 52 but being somewhat shorter. Farther back along the channel bar toward the right, be

nates in an upstanding portion 57. The

channel bar 43, best illustrated in 9,

' being similarly constructed to the channel bar 44, the corresponding parts are similarly numbered. Before describin the mounting of the channel bars or carriers it may be well to describe the releasing members or ratchet bars, which are arranged within the channel bars and control the releasing pins.

There are two cam or ratchet bars, rights and lefts but otherwise similar in construction. -The one that co6perates with the channel bar 43 is numbered 58 and is most fully illustrated in Fig. 9, althoughit is there shown behind the channel bar 43. The other ratchet bar 59 cotiperates with the channel bar 44 and is fully shown in Fig. 11.

A description of the front ratchet-bar 59 will suffice for both, the corresponding parts of the ratchet bar 58 being similarly num-- bered. The ratchet bar 59 comprises a vertically disposed bar or body portion 60, provided along its upper ed e with a series or set of ratchet teeth 61 orming a ratchet, this ratchet being arranged to the left of the middle of the bar. The front vertical face of the bar 60 is provided with a series or set of projecting cam devices 62 which project outward from the face of the bar and are preferably made of pieces separate from the bar and which are suitably secured to it.

Each'cam piece 62 comprises two horizontal portions, one above the other, numbered respectively 63 and 64, and a connecting diagonally arranged portion 65 which is the cam proper. There are five'of these cam pieces 62 in the present instance secured to the bar 60. While the general construction is similar they vary one from another, as more fully described later on, so as successively to control the releasing pins with which they coiiperate.

The releasing pins aforesaid, designated by the reference character 66 and illustrated in Figs. 1 to 4, 7, 13 and 14, are upright pins arranged to slide freelyv in theopenings 50 and 51 in the reciprocating members or channel bars, their lower ends being reduced, as indicated at 67 to facilitate coiiperation with the plungers 33. Each pin 66 at the inner side facing the channel bar is cut or otherwise formed to provide a notch or cutout 68. This notch, as will be understood from Figs. 4 and 7 has its upper wall partly inclined and partly horizontal and its lower wall or edge similarly formed, the inclined portion of the upper wall being at the left and the inclined portion of the lower wall at the right. The ratchet bars 58. and 59 are arranged within their respective channel bars between the body portions 45 of the bars and the releasing pins 66, the cam pieces 62 passing through the notches of their associate releasing pins, thus preventing the releasing pins from dropping out of the releasin hand, it will be noted serve to connect the releasing members or ratchet bars with their associate channel bars and prevent said ratchet bars from dropping out of place. The right-hand ends of each of the bars 60 are provided with outwardly extending stop pins 69 which are adapted to coiiperate with the right-hand releasing pins to prevent leftward withdrawal of the releasing members 58 and 59 from their channel bars. p

The channel bars 43 and 44, together with members and releasing pins, for which t ey serve as carriers, are supported to reciprocate slidably on roller bear-' ings above the top plate 2. To provide such bearings two brackets 70' are mounted on the top plate 2, one near each end. Said brack ets, illustrated in Figs. 1 to 4, are generally U-shaped, comprising two uprights or standards 71 and a connecting base portion or cross bar 72. Through the cross bar 72 of each bracket pass screws 72 which serve to secure the bracket to the top plate. Screwed into the outer face of each standard 71 near -its top and bottom are headed screws 73 havinglong shouldered portions 74 which provide bearings for rollers or spools 75. Each spool has an inner flange or head 76 corresponding in diameter with the. head of its screw 73. The channel bars are slidably supported on the rollers 75, each channel bar co6peratin with four of these rollers, there being a pair of rollers to coiiperate with the top and bottom of each channel bar near either end thereof. The lower roller of each bar supports the weight of the channel bar through one of the ledges 47 which rests on said roller. The upper roller prevents upward displacement. The spool heads or flanges 76 prevent inward displacement of the channel bars or displacement toward each other, while the heads of the screws 73 prevent outward displacement; said heads coiiperating with the edges of the ledges or lips 47 and 46 (see particularly Fig. 13).

"T he back faces of the body portions 45 contact-with the flanges 76. The construction it will be perceived is such that while the channel bars may move or slide back and forth freely on their roller supports, they means being illustrated in Figs. 1, 2, 4 and 20 ends in two parallel cross heads 85. The

14 to 16. A bracket or journal bearing 77 is secured by screws 78 to the top plate 2 near its left-hand end and midway between the rows of bomb openings, said bracket having a cylindrical ortion 79 which is bored out to receive a s laft 80 of a lever member or handle designated as a whole by the numeral 81. The shaft 80 is adapted to project beyond the ends of the journal or bracket to provide bearings for the lever member, and after the parts have been assembled the shaft is preferably pinned or otherwise secured in the bracket so'that it will remain stationary during operations of the lever member. Said lever member comprises a handle proper 82, terminating at the top in a ball or finger piece 83 and gradually thickening from the top to the lower end where it is provided with a transverse integral cross bar or arm 84 that terminates at its lower ends of the cross heads are rounded and bored out, as indicated at 86, to cooperate with the end portions of the shaft 80, about which the lever member 81 swings as a center. The upper ends of the cross heads are thickened or provided with bosses 87 on their outer faces which are .tapped to receive shoulder screws 88 that provide bearings for pawls 89, said pawls extending downward and toward the left and terminating in broadened teeth 90, one tooth 90 coiiperating with the ratchet or teeth 61 of the releasing member 58 and the other with the ratchet or teeth 61 on the releasing member 59. The pawls 89 pass downward through the slots 52 in the. channel bars, and it will be understood that they may operate on the releasing members through said slots without affecting the channel bars until the pawls are brought in contact with the stops or abutments 53 at the left-hand-ends of said slots. The backs of the cross heads'85 are provided with cars 85" which provide bearings for a cross shaft 91 to which-outside the ears are fixed arms 92, said arms at their free ends having short lateral pins 93 that cooperate with a hook bar hereinafter described.

In order fully to complete at this time the description of the member 81 and the devices supported on it, it may be set forth that the shaft 91 is controlled by a crank arm 94 that is fixed to it forward of the handle proper 82 and extends leftward, the free end of said crank arm having connected to it the lower end of a connecting rod or wire 95 that ex tends upward substantially parallel with the handle proper 82 and at its upper end is connected to an angular hand lever 96 that straddles the handle and is pivoted at 97 to an car 98 integral with said handle. The finger piece or hand lever 96 has a movement relative to the handle that is limited by stops or lugs 99 projecting from the forward side be conveniently manipulated by one hand of the operator. The latch 96 and connected parts are maintained normally in the position shown in Fig. 4 by a coiled spring 100, the lower. end of which is anchored to an ear 82 projecting from the handle 82, the upper end of said spring, as appears from Fig. 2, being booked through a hole in the upper end portion of the connecting rod 95. This upper end portion, indicated at 95, is angularly disposed to the body of the rod and passes through a hole in one side of the latch piece 96. The construction is such that the spring connection with the portion 95 between the parallel ears of the latch prevents accidental detachment of the rod from the latch.

The member 81 is provided with a coiled restoring spring 101, one end of which is hooked through a hole in an ear 102 projecting rightward from the handle 82' near its lower end, the other end of said sprin being anchored to an angular plate or brac et 103 which is riveted or otherwise suitably secured to the top plate. A back stop rod not shown is provided interiorly of spring 101, to limit the contraction of the spring and serve as a backing for lever 82.

Back pawls or detents are provided to maintain the relationship between the controlling members or ratchet bars'and the channel bars. Said pawls, desi ated as 104, are pivoted on screws 105 which are secured in the holes 54 in the standards 54.

-The pawls 104 are gravity or spring conof the coiled springs 106 are anchored to f webs or projections 107 on the bracket arms 71, and which are providedeach with upper and lower holes; The springs 106 are hooked through the lower holes of the webs and thence extend horizontally leftward, the left-hand ends of said springs bein hooked through holes in the portions 57 of t e angular fingers 56. The effect of these springs 106 is normally to maintain the stop faces 48 of the channel bars in contactive engagement withthe low'er left-hand rollers 75, as appears in Fig. 4. From this figure it' will be plain that the movement of the chennel bars toward the left will be limited by the engagement of the stop faces 48 with said rollers.

Referring now to the means for controlling the stripping of the safety devices or wires 7 from the bombs 3, said means comprise stripping or hook bars illustrated in Figs. 1 to 4 and 12 to 15. Said hook bars comprise bars proper 108 formed along their upper edges near the left-hand ends with slots or notches 109 and 110 connected by curved surfaces 111. Near its left-hand end each bar is provided at its inner face with a stop pin or lug 112. Somewhatto the right of its middle each bar has on its rear face a grooved pin 113. Arranged at intervals along each bar are hooks 114, there being five hooks on each bar in the present instance, or one hook for each bomb wire. These hooks are broadened or splayed, as indicated at 115, the splayed portions receiving rivets or other securing means by which the hooks are secured to the bars on their inner faces or the faces nearest each other. Thence the hooks extend outward away from each other under the bars in a general horizontal direction and terminate in downwardly bent and lef wardly extending end. portions or hooks proper 116. The hook bars are slidably mounted on the bracket arms 71, being arranged between said bracket arms and the spool flanges 76, the bracket arms being cut or shaped to provide a passage-way for the hook bars so that they may slide freely lengthwise Coiled springs are hooked over the pins 113 and extend thence toward the right. being hooked through the upper holes in the webs 107. l hese springs urge the hook bars constantly toward the right and the stops 112 prevent excess movement of the hook bars in this direction, said stops being adapted to coiiperate with the faces of the left-hand standards 71. Normally the hook bars are limited in their rightward movement by reason of the engagement of the pins 93 with the notches 110 in the hook bars so that at this time the hooks 116 are clear of or to the right of the cross portions 8 of the wires 7.

Means are provided indicating to the operator the Various relationships of which the channel bars and ratchet bars are capa ble, or in other words of indicating the'number of bombs which have been dropped. Such indicating means may be preferably scale and pointer devices which comprise, as best shown in Figs. 1, 10 and 11, a scale indicated at 117 that is cut or otherwise suitably formed on the ledge 46 of the channel bar 44. With this scale coiiperates an angularly shaped pointer 118 secured to the base of the ratchet bar 59 by screws 119 and looping around the ledge 46, terminating above said ledge in a beveled pointer proper 120:

The pointer and scale are shown in Fig. 1

as indicating that one of the bombs has been dropped but for descriptive purposes it is desirable to assume for the moment that no bomb dropping operation has as yet, 00- curred, and consequently the pointer will be one step to the right, or opposite the 0 on the scale, said scale running from 0 to 10 since the capacity of the magazine is ten bombs.

Referring to the operation of my inven tion, it will be understood that normally the locking plungers 33 are engaged with their respective controllers 21, which at this time maintain the grippers positivel locked in engagement with the bombs. lso the releasing pins 66 are in register with their respective locking plungers or pins but are above and out of contact therewith. The general views show the parts after the first operation, which has been effective to advance the ratchet bars 58 and 59 one space to the left relative to their channel bars and as a consequence to cause the left-hand cam piece 62 on the ratchet bar 59 to act on its releasing pin to effect a release of the associated bomb. It will be understood, howhowever, that before this operation has taken place the cam or diagonal portion 65 of the cam piece aforesaid is at the right of its releasing pin and has not as yet affected it. Let it be assumed that the parts are in this last mentioned relationship, and that the operator desiring to drop or discharge a bomb, pushes the finger piece 83 in the direction of the arrow in Fig. 4, or toward the left. The first effect of the movement of the finger piece 83 and handle 82 is to cause the pawls 89, acting on their associate ratchets 61, to move the ratchet bars 58 and 59 toward the left, the parts being so proportioned and arranged that this movement will cause the diagonal cam portion 65 of the left-hand cam piece 62 on the ratchet bar 59 to engage with the cam slot in its associate releasing pin 66 and depress said pin or slide it downward in its bearings in the channel bar, which as yet remains motionless.

It may be well at this point to refer some- 115 what more in detail to the variations of the cam pieces 62. -As stated, the cam pieces 62 are generally similar. Their horizontally disposed portions 63 and, 64, however, differ in length. As shown, the upper horizontal 120 portion 63 of the left-hand cam piece 62 on the bar 59 is quite short and the lower horizontal portion 64 is'quite long. Referring next to the right-hand cam piece 62, its upper horizontal portion 63 is somewhat 125 longer than the portion 63 of the left-hand cam piece, while the lower horizontal portion 64 of the right-hand cam piece is somewhat shorter than the portion 64 of the lefthand cam piece. The three intervening cam 130 pieces vary it will be seen in the respect described from one another as well as from the end or left-hand and right-hand cam'pieces. The cam pieces 62 on the ratchet bar 58 also vary from one another as well as from the cam pieces of the member 59. In other words, all of the ten cam pieces on the two controlling members or ratchet bars 58 and 5 9 are different from one another in the respect stated, so that the timing of the operations of the releasing pins which they control may be successive or progressive. It will be understood, of course, that the cams may be arranged on the ratchet bars so as to become effective in any desired order; or in other words, their arrangement is selective and at the will of the constructor. After they have been thus arranged, the result will be to cause the bombs to drop in predetermined succession or order. In the 'present instance, the order in which the bombs will drop will be readily grasped from comparing the lengths of the upper horizontal portions 63 of the cam members. .This order has been determined in the present instance by the consideration that it is a desirable to keep the magazine and the air{ craft on which it is carried as evenly trimmed as possible.- The bombs are of con-' siderable weight and if they were drop ed from one end straight back toward the ot er.

end without change, the lossof weight would not be evenly distributed. Accordingly, as will be understood from a comparison of Figs. 9 and 10, the bomb at the left-hand front end of the set will first be dropped, followed b second, the one at the right-hand rear en and thence successively by, third, the one at the left-hand rear end; fourth, the one at the right-hand front end; fifth, the one next to the right of the first one discharged; sixth, the one next to the left of the second one discharged; seventh, the one nextto the right of the third one discharged; eighth, the one next to the left of the fourth one of the ones in the rear line, as viewed in Fig. 1. However, the order of discharge is not fixed but may be varied as desired, either by changing the cams on the bars or by substituting the illustrated ratchet or cam bars by other bars having different cams or pin actuating or moving means.

Returning now to the effect of the downward movement of the left-hand front releasing pin in its bearing under the action of its associate cam piece 62, it will be understood that the reduced end of said pin 66 engaging with the underlying plunger 33, will move said plunger downward out of the hole 34 in the controller 21, the releasing pin taking the placed the plunger 33 and thereby connectin the controller with the channel bar 44. tmay. be here remarked zine from the force 0 ombs dro that as a matter of precaution it is preferable to provide a slight groove or depression, indicated at 121 (Figs. 6 and 7 in the thickened portion 13 of the top plate in order to allow a margin of safety for the operation of the plunger 33 and its pin 66. The effect of this construction is to enable the parts to work properly even if the lower end of the pin 66 should be depressed slightly below the bottom surface of the controller, whereas if the controller were in direct contact with the part 16,.the pin 66 contacting with the side of the depression 35 would block the controller against sliding movement. The operation of depressing the plunger 33 is effected by a swinging to the left of the handle 82 which is sufiicient in extent to bring the ends of'the pawl teeth 90 into contact with troller 21, that has been coupled with the channel bar 44 by its engaging pin,;will participate in this leftward sliding movement, causing the associate grippers to be opened as has been described, and releasing the bomb which will dro through the maga- 'gravity, as has been heretofore explained. n Figs. 6 and 7 one of the controllers is illustrated in the position it-will occupy after it has been slid leftthe associate grippers, although the particular parts here illustrated are not the ones whose interaction is now being described. It will be seen that after the pin 66 passes tothe left of the plunger 33, the latter will be maintained depressed by the stem 22. The bomb wire will be automatically stripped as the .bomb drops owing to the fact that the hook bars have been slid leftward during the described operation by reason of the engagement of the pins '93 wit the slots 110, the movement of the hook bars bringing the hooks 116 under the transverse ends 8 of the bomb wires, so that as the bomb drops the wire will be stripped from it b the hook. Normally as has been de-- scri d, the hooks areto the right of the ortions- 8 of the wires so that should the accidentally by reason of defec'tive grip er action or for any other cause, the sa et wires will remain. in lace thereon. The eft-hand movement 0 the channel bars will be limited b the coaction of the-stop faces 48 with t eir associate rollers 75. On releasing the hand lever it will be restored to normal position, together with the parts carried by and connected to it, by the spring 101. At the same time the channel bars will be moved back to normal position by their restoring springs as will the hook bars. The return movement of the .ward by its releasing pin and,has opened channel bars will be participated in by the asse -as ratchet bars supported on them. It will be understood, however, that the first or preliminary movement of the ratchet bars toward the left, independent of the channel bars,-will not be lost but that by reason of the engagement of the detent pawlsf104 with the ratchet bars the ratchet bars will have been advanced one ste leftward in relation to the channel bars. his will be plain from a consideration of Figs. 1 to 4, in which the parts are shown in the normal position following the'described operation which has been effective to release the first bomb or the one at the left-hand end of the front row.

As a result of the relative movement between the ratchet bars and their associate channel bars, by which the ratchet bars have been advanced on step to the left of their channel bars, the parts will now be in such relationship that at the next operation of the handle 82 the cam piece at the right-hand rear end of the set will become eifective on its releasing pin, and consequently the associate bomb will be dropped as the handle 82 nears the end of its stroke. On releasing v the handle the parts will be restored, as has been described, and successive operations of said handle will result in the discharge of the bombs one after the other in the order that has been set forth.

My invention also provides for discharging simultaneously any desired number of bombs, and to this end it is only necessary as a preliminary to operate the hand lever 82 less than its full throw a number of times corresponding to the number of bombs that it is desired to drop. In thus operating the hand lever it will be moved from normal position to the left only far enough to bring the pawl teeth 90 into contact with the abutments 53. As soon as the operator feels this contact take place, he reverses the handlever and pulls it back to normal position, after which he again partially operates it. These successive partial operations or short strokes may be effected with comparative rapidity. As a result it will be understood that the ratchet bars will be advanced step by step relatively to the channel bars and that at each step by step movement one of the coupling pins will operate, unlocking the associate controller and connecting it with the channel bar. Since, however, the channel bars themselves are not affected by these partial operations, no movements of the controllers will take place and no bombs will be discharged. The desired number of controllers having been connected with the channel bars, the operator effects a complete actuation of the handle 82, giving it its full stroke and causing it to move the channel bars leftward, together with all of the connected controllers, thus releasing simultaneously the predetermined number of bombs.

Sometimes it may be desired to drop the bombs so that they will not explode on striking; for example, the aviator may meet with an accident or may be pursued by the enemy in force, and may consequently desire to lighten his machine when not over hostile territory. In such circumstances the bombs should be dropped without stripping the safety devices or wires 7. To accomplish this result it is only necessary to operate the latchor finger piece 96 preliminarily to actuating the handle 82. Accordingly the upper end of the latch is pulled toward the handle, causing said latch to turn on the pivots 97 and pulling up on the connecting wire 95, which, acting on the crank arm 94, will turn the shaft 91 in its bearings, swinging up the arms 92 and lifting the pins 93 out of the notches 110 in the hook bars 108, thus disconnecting said hook bars from the handle 82 which may then be operated, as has been described, to discharge the bombs. The hook bars, however, will not participate in the movement of the handle and the pins 93 will slide over the surfaces 111 and into the notches 109 during the handle movement during which said hook bars will be retained in normal positions by their springs and the bombs will drop without the bomb wires being engaged by the hooks 116. By maintaining the latch 96 pressed back toward the finger piece 83 during the successive operations of the handle 82, all of the bombs may be dropped so that they will not explode or be discharged on striking.

It will be observed that by my present invention there is provided a combination of means for holding a plurality of bombs, and

means controlled by a single handle for releasing or discharging the same; that in the i present instance the means for holding the bombs are means that operate to retain the bombs securely in a container or magazine; that in the present instance, the means for releasing or discharging the bombs are means that operate to free the bombs which thereupon are dropped from or discharged from the magazine by the force of gravity; that means are provided for releasing bombs or other missiles in predetermined order; that means are provided for releasing at will at a single operation any selected number of a plurality of bombs or other missiles; that separate means are provided for holding each bomb in combination with means for rendering inoperative said separate holding means; that means are provided for rendering the separate holding means inoperative in predetermined order; that means are provided for rendering inoperative the separate holding means singly or simultaneously to any desired number; that in combination with separate holding means for each bomb there are provided releasing devices, one for each holding means, normally operative looks for said releasing devices, and means for rendering said locksinoperative; that' being mounted on a hand operated reciprocatory carrier, slide bar, channel bar, or support; devices on said channel bar being provided for operating the relea ng 'pin or pins, said devices comprising moving devices, ratchet bars or cam bars, which are provided with cam pieces, or releasing pieces which differ or vary one from another; that the controllers for the rippers are comprised in a set arrange in two series of parallel lines, corresponding to the parallel lines or series in which the grippers are arranged; that the set of lockmg pins is likewise divided into two series or parallel lines corresponding to the parallel lines of the grippers, as are also the releasing pins; that means are provided for varying the relationship between the cam bar or ratchet bar and its support or channel bar, and for retaining said ratchet bar in set relationships with said support; that a hand operated pawl cooperates with the toothed portion or ratchet on the ratchet bar or cam bar to move said cam bar step by step relatively to the channel bar, said pawl cooperating also with i the channel bar to move the channel bar itself longitudinally, this movement of the channel bar taking place during the latter part of the awl stroke while the relative movement efected between the channel bar and the cam bar is caused by a movement of the cam bar onl during the first part of the pawl stroke; an that the cam bar is thus moved step by step relatively to the support, in the present instance the channel bar, while said support is reciprocated, or moved in the present instance to the left and back again, at each of these step by step movements; 2'. e., the

- complete operation of the hand piece or lever from right to left and back again to normal position effects an advance or step toward the left of the cam bar and also a reciprocation of the channel bar.

Various changes may be made without departing from my invention.
