7 Claims.

The invention relates to bomb releasing racks, particularly adapted for use with aerial bombs. The principal object of the present invention is to provide a simple Vdevice which is rugged in construction and fool proof in operation for releasing the bomb.

Another object is to anism for a bomb rack electrically or manually. Y Another important object is to provide an arrangement of parts in which a minimum amount of energy is exercised to operate the releasing mechanism for a substantially heavy bomb. Thus the operating parts, both electrical and manual, may be quite light in weight and it is a well known fact that any saving in weight is an important feature in this field. Other objects and advantages will become apparent as this specification proceeds. Referring to the drawings forming a part thereof and in which a preferred form of the invention is illustrated:

Fig. 1 is a side elevation of the complete bomb rack; Fig. 2 is a fragmentary detail elevational view with one of the side plates removed and the parts in the locked position;

Fig. 3 is a View similar to parts in the released position;

Fig. 4 is a fragmentary detail sectional through the trigger member of the manually controlled operating means; and

Fig. 5 is a crosss-sectional view taken on the line 5-5 of Fig. 3.

Referring again to the drawings the framework or supporting structure of the shackle comprises two spaced plates I-l resistance welded or otherwise secured to a channel member Il. A bomb supporting hook I2 is mounted between the two side plates and pivoted therein at I3. A ring or other suitable member indicated at I4 in Figs. 1 and 2 carries the bomb (not shown). Shocks I5 are provided adjacent either end of the rack to position the bomb and prevent it from swinging.

Releasable locking means for the hook is generally indicated by the reference numeral 20. Means indicated at 2l are provided for dropping the bomb armed or unarmed but as this means forms the subject matter of another application no further description of it is necessary.

- The releasable locking means may be operated electrically or manually. Naturally the automatic electrically operated means is preferred but there is always the possibility of something provide a releasing mechwhich may be operated Fig. 2 showing the going wrong electrically and it is therefore considered important to provide a manually operated means which performs the same function as the electrically operated means and for the sake of simplicity utilizes the mechanical parts of the electrically operated means. The operation of the electrically controlled releasable locking means will now be described.

Fig. 2 shows the releasable locking means in its locked position it being understood there is a bomb suspended in the rack, and Fig. 3 illustrates the locking means in its released position, after being electrically operated, to permit of the bomb being dropped. The manual and electrical parts of the releasable locking means are mounted as a unit to permit of their ready removal from or assembly with the shackle. For this purpose a channel member 22 is secured to the side plates l0 by screws, bolts or pins 23 and 24. 'Ihe manual operating means and the electrical parts are mounted on the channel member as will be hereinafter apparent. Thus should any of this mechanism be damaged or get out of order the entire unit may be quickly removed and a new one substituted without disassembling the rack.

A solenoid 38 is mounted on a plate 3| secured to one end of the channel member 22. A headed pin 32 formed as part of the solenoid core engages an opening 33 in a lever 34 which is pivoted at 35 in the sides of the channel member 22. A spring 36 urges the pivoted lever 34 away from the solenoid or in a direction of what might be termed against the pull of the solenoid.

The upper end of the pivoted lever 34 has a notch 31 and this notch engages the end of a long arm 40 of a bell crank lever 4l pivoted at 42 in the side plates l. The short arm 43 has a' hook 44 on its lower end which engages a toe 45 on the bomb supporting hook I 2 when the parts are in the locked position of Fig. 2. 'A spring 46 normally urges the short arm 43 away from the bomb supporting hook l2 and the long arm downwardly and away from the notch 3l in the pivoted lever 34 when the parts are in the released position of Fig. 3. A stop 46 extending between the side plates It limits the downward movement of the arm 40 and the upward movement of one end of the bomb supporting hook I2 in the released position. A nose 41 on the hook l2 which may contact the long arm 40 limits the upward movement of the other end of the bomb supporting hook.

The manually operated releasing means comprises a trigger 5l) which is pivoted at 5I in ears The loop 59'has an operating connection 56' by.

virtue of which it may be pulled at any angle within 180.

The pull cable passes under a stud Se andit is thought to be apparent an upward pullon the loop 59 will cause one endofthehtri'ggerto be raised. The spring 55 acts as an over-.travel spring to eliminate the need for exact adjustment on the operating cable .and vasabuier spring to prevent undue strain on the parts.

The ends of the stud Si) extend beyond the sides 4Vof the triggermember yand theends ci a spring -Gl are loopedaround the extensions of the`V stud andithe other end of thespring engages the channel member il. This spring functions to;maintainzthe .trigger in its locked position.

.The end of `the trigger adjacentthestud 55 has.: an extension' 52. As shown inv Fig.v 2 inLthe locked position this extension engages a cam surface B3 'ormedin the top of ,the opening 33. Anupvvardpull onthe trigger will cause the. eX- tension 62 to .camthe .pivoted.-lever134tothe release position of` Fig.'8, the samey asirtiie. solenoid i3d Vwere energized. "The end of the `long arm .48 of. the'beil;crankleverwill be disengaged fromV the nctchfi, the hook ifi on the short. arm 43 vwill .pass from vunder the noseV 45 von the bomb supporting leverland the bomb vwill drop.

'Switches and 65 are carried bythe channel member 22, The operation of the switch 65 is controlled by a contact'ngerl 'carried by the pivoted lever 3i. `In operationwhen the rack-is loaded thel switch-pin is not in-contact with the finger S61. When the solenoid is energized or the trigger Eil-.pulled upwardlythe contact'nger 61 and-pivoted lever 34. move away 'from the switch pin but after the releasing mechanism has been tripped-and the current cut to the solenoid or the trigger allowed to Idrop theJ spring 3S moves the'lever'l andnger '-61 to opferate'fthe switch-and direct the electrical charge to'the following station.

vThe-switch 65 is anormally closed `switch and controls the tell-tale light or asignar inf the bombardiers-station. In the locked-positionofFi-g. 2 afnose' 584 on the bomb supporting-hook i2'engages afspringi-.GQ which'maintains the switch pin in its closedwposition. When the bomb vis dropped the noset' moves away from the spring 69, the switch 'pin is allowed to move outwardly, the circuit is broken and the light designating this` particular bomb rack goesout, thus informing the bombardier the Ybomb has been dropped.

r'lhe operating parts of the'releasing mechanism are autoinaticallyset when anewbornb is positioned in ,the rack. .The ring or loop. lllengages the hook l2 in its vreleased-position -and the upward` orforwardforce applied to the lower edge of `the hook will cause the nose 41 to contact thelcng arm-4? of the bell crank lever-and automatically throw all-.ci the internal -latching mechanism to the locked position.
