2 @1312 This invention relates to serial bombs, and

, more particularly to means for detoneting the Another object is to provide a detonsting mcsns I for aerial bombs adopted to incr the eiTectiveness thereof by detonoting thebombs Just prior to striking the ground.

Other objects end edventoges will appear. and be brought out more fully in the following specifipotion, reference being hsd to the eccom drewing, wherein,

Fig. l is e side view partly in section embodying my invention. v

Fig. 2 is a. partial view in section of the forward end oi the same and showing the detonating mechanism in extended position.

Heretofore eeriel bombs of e type dropped by airplanes have been detonated upon striking the ground and n large percentage of power, often as much as seventy percent, is ineffective, this energy resulting only inmching a hole in the ground. Therefore, it follows that if the bomb could be exploded a second or two previous to the impact of the be with the und, the explosive force thereof would have greater effectiveness then. otherwise. Such. as result is achieved by this invention as will beept from the following description.

Referring more particularly to the dre, I show u bomb 5 oi the type usually carried by sir-= plumes end the like, having at chamber 8 for the explosive charge, end having a tapered nose or end portion l and a plurality oi tsil fins d. A cross of a. bomb well 9 loans the front end of chamber-6, end the nose l is provided with an open end iii.

A pair of longitudinal partitions l l extend from the well e to the open end iii and form e. chemis provided with a ceive a threaded the ground, the

tapped bore 23 adapted to restud 24 which passes through the hole 2% by which means the cap 2| is accured to the nose I.

The stud 2c is formed its outer end which will in flight and unscrew the stud 24 and release the cap 2! from the nose I.

A look screw 28 is positioned plummet l3 and engages the rod IS with sufficient pressure to keep the rod l9 separated from the contacts It. -The pressure of the screw 26, however, is such that when the plummet l3 strikes impact of the cap 2| will cause the plummet E3 to be advanced along the rod I! causing the latter to complete the electric circuit between the contacts with an air screw at charge.

the explosive her i2 adopted for the accommodation of a plummet lil secured by a. chain id to the wall 9. These partitions also form two compartments in'which ere-arranged the batteries, ds later described.

The explosive charge is adapted to be detonated by an electric current from one or more electric batteries lb suitably secured to the well 9 or otherwise. Wires id connect the batteries 55 to the explosive charge, and

wires ll connect the batteries id to a pair of contacts l8 suitably secured in the plummet I8.

which may be supplied v A metallic rod lQ-is positioned in a bore Ed in the plummet i3 and is provided closes the open end Id of the is provided with a bore hole bomb. The cup 29 2 and the nose l with a. cap 2i which Fins 8 are each provided with a curved terminal portion 2i, the function of which is toretard the bomb 5 suiliciently to permit the plummet I; to fall out in advance of thebomb after the cap 2| has been released by the air screw 25, the plummet however being held by the chain ll the length of which may vary from a few to several feet as may It will thus be apparent that by the foregoing construction, the bomb will be detonated a few feet before striking the ground and the full explosive power will be eflective otherwise than by it"! v. .1 I 5 a large hole in the ground ving described my invention what I claim is. t 1. In combination, an explosive carrying aerial w o. having an elongated body, means forming a restricted chamber in the forward end thereof, a, plummet stored in said chamber, a chain in said chamber and connected to the body and the plummet for limiting the distance the plummet may leave the body, means for detonating the explosive including batteries in the body on the outside of the restricted chamber, contacts intho plummet and wires connecting the contacts in a circuit including the batteries, a cap closing the end of ssidchamber, a sliding rod in the plummet connected to said cap for closing the said contacts, and an air propeller operated screw securing said cap to the body, whereby the cap and plummet are released after a predetermined time of travel of the bomb.

2. In combination, an explosive carrying aerialturn when the bomb is,

laterally in the l8 thus detonating the be determined upon by actual conditions.

an air propeller having a screw threaded shaft met, and cables stored in the restricted chamber connected in circuit with the batteries, contacts and explosive charge for detonating the same, a

rod passing through the plumrfiet and normally held out of contact with the contacts, and an enlarged head carried by the outer end of the rod.

and closing the end of the restricted chamber and extending beyond the periphery thereof, and

passing through the edge 01 the enlarged head and into the body or the bomb for securing the same to the body, whereby the cap and the plummet are released after a. predetermined time 0! travel of the bomb.
