BOMB-RELEASE GEAR.

Application area June 7, 1919. Serial No. 302,585.

(FILEDUNDER THE ACT OF MARCH 3, 1883, 22 STAT. L, 825.)

To (ZZZ whom it-mag concern:

Be it known that I, HARRY D. WEED, a citizen of the United States, stationed at McCook Field, Dayton, Ohio, have invented an Improvement in Bomb-Release Gear, of

which the following is a specification.

The invention described herein may be used by the Government, or any'of its ofiicers or employees in' prosecution of work for the Government, or by any other person in the United States, without payment of any royalty thereon.

This invention relates to a-bomb release gear. for airplane bombs.

The principal object of this invention is to provide a bomb release gear with a two point support for a bomb, that will release both of said supports at precisely the same instant.

It is afurther object of this invention to .provide a pair of bomb engaging hooks and means interconnecting the hooks so that the weight of the bomb as it is supported by the.

hooks tends to move both of the hooks and the inter-connecting means in the same direction.

. It is a further object of this invention to provide a double and releasable locking means for-said hooks, whereby accidental release of the bombs is effectually prevented. g It is a further object of this invention to design a-hanger provided with unequally spaced'means for engaging with a suitable support, whereby the improper engagement of the hanger with its support is guarded against.

Other objects and advantages will appear the U-shaped hanger 1. This locking means as the description proceeds.

In the drawings illustrating one embodiment of my invention, Figure 1 is a top. view of the-bomb release gear.

Figure 2 is a side view, partly in section.

Fi res 3 and 4 are views showing successive stages of operation of the releasing mechanism.

Figure 5 is a bottom view.

Figure 6 and Figure 7 are perspective views showing parts of certain details.

The bomb release gear comprises the hanger 1 made of sheet metal bent along the line 2 into a substantially U-shaped form. The upper ends 3' and 4 of the hanger are secured together by any suitable means. Ends 3 and 4 are provided with unequally spaced apertures 5 and 6 respectively, the unequal spacing making it impossible to engage the hanger on its support wrong end to, as more particularly set forth in my copending application, Serial No. 302,586 filed June 7, 1919. p

' .-A pair of hooks 7 and 8 are pivoted at 9 and 10 respectively at opposite ends of the hanger 1 and between the sides thereof, and

project outwardly therefrom through suitable apertures. The lower ends of these hooks support the bomb carrying rings 11 and 12 and so provide a two point support for the bomb.

parent that the hooks 7 and 8 and bar 13 are movable absolutely simultaneously, and furthermore that the weight of the bomb as it hangs on the hooks as shown in Figure 2, tends to move the books 7 and 8 and the bar 13 to the left.

The releasable locking means for the bar 13 will now be described. -Pivoted to the bar 13 at 18, and projecting through one of the apertures 16, is a locking sear 19, provided with a notch 20 that engages with the locking stop 21 suitably secured to the hanger 1. The sear 19 is held in its locked position by spring 22 interposed between thief portion 17 of the bar 13 and the sear itse A second locking means is provided by a trigger 23 pivoted at 24 between the legs of comprises a locking notch 25 that is positioned just over the end 26 of the sear 19. It should'be noted that the notch 25 and end 26 are slightly spaced from one -another.

The trigger 23 is provided w portion 27 engaging with the unde edge of the sear 19. The trigger '23 is normally urged to the left by a spring 28.

The operation of parts will now be described. With the'bomb carrying rings 11 and 12in place on the hooks and the trigger and sear in the positions shown in Figure 2,

it will be apparent that the weight of the bomb will tend to move the bar 13 to the In order to release the bomb the trigger 23 is pulled to the right, as shown in Figure 3 thereby releasing the sear from the trigger.

The cam portion27 of the trigger now lifts the sear 19 until it is disengaged from the stop 21, whereupon the bar 13 and hooks 7 and 8 move to the left to simultaneously release both bomb hooks, as shown in Figure 4.

End 26 of the sear is normally slightly spaced "from the notch 25 of the trigger.

As long as the spring 22 functions properly, these parts are spaced as shown in Figure 2. But if the spring 22 is lost or broken, the proximity of end 26 and notch will eflfectually prevent premature release of the sear, and W111 prevent it from being unlocked until the trigger 23 is actually pulled.

While I have illustrated a possible em-.

bodiment of my invention it should be understood that it may be carried out in other wzgys as defined in the following claim.

claim as my invention In a bomb release, a hanger, a hook pivoted to said hanger, said hook being so designed that the weight of a bomb tends to move the hook in a iven direction, a sto a bar pivoted to the 00k, a sear pivote to the bar and movable With'the bar and hook,

the sear normally engaging the stop to lock the hook against movement, and a trig r normally locking the sear in stop engagm position and movable to release the sear an trip the same to stop disengaged position.
