To all whom it may concern Be it known that 1, JOHN erence being had tothe accompanyingfdrawings, form ng a partof this specification,

and to the reference numerals marked there- My present invention relates to explosives and more particularly to bombs of the kind required to be thrown by hand and fired by impact. The object of my invention is to provide a simple and efiicient device of this.

character which can be thrown as a ball without possible danger of premature-explosion. A further object of my. invention is to provide a bomb of this character which is absolutely safe against accidental dis charge in the hands of the user, but whlch v will explode'with certainty upon impact. 7

Another object of my invention is to provide a bomb which is safe and efficient. and which can'be made of any form most-con venient for the user. More specifically, the

object of iny invention is to provide-a bomb comprising two spaced members, one/off which contalns an exploslve and meansfor discharging the same, whichlmeans is normally locked but which .is released when said members aremoved relatively to each other by impact. To these and other ends the invention resides in: certain improvements and combinations of parts all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end ofthespecification r In the drawings p p l Figure 1 is a plan view of my improved bomb with a portion of tioned away;

Within the outer shell 1 is a second shell 2 formed of heavier metal and constructed with an inner. cavity 3 having an opening through its euter wall through which an exploslve may be introduced into the cavity 3.

The opening may be closed with a screw, plug, or other suitable means 4. 'The'wallsj of the inner member or; shell are made with" thicl zened portions so that when the exploslve contained. within .the shell is. fired, theshell wlll brea'k into'fragments along the weakenedportions- Diametrically through] V the inner shell is an opening or recess..5 adapted to. receive a sleeve or hollow shaft (5 adapted to project at its ends jfiroinf the shell.

Slidably mounted within the sleeve 6 are a pair of locking devices in the form 'oipins 17 having rounded heads the wall ofthe outer shell, and support the inner shell within the outer shell. Each of the locking pins 17 has a projection 18 adapted to engage a slot19 formed in the trigger adjacent its central opening. The sleeve 6 1s also provided with a slot extend= ing from its central opening through the hear ng portion upon whlch the trlgger 1s mounted and into the enlarged portion ad jacent thereto. V The operation of the parts already described is as follows: I The inner shell receives a charge of ex-v plosive and the screw or plug a is placed in position. v placed in position and the; triggers moved to the position shown in 1 of the draw ings, in which position they arelocked by engaging with the lugs 18 on the pins 17, which are held from rotaton by engagement with the slots in the sleeve 6. When in the;

position-shown in F ig. 1 the springs 13 are under tension and tend to rotate the triggers 10 in the direction of the arrow shown in r V tween the spring pressed triggers 10 and the Fig. 1 to'itorcibly strike the pointed end of the trigger against the primers. 'The'locked position of the triggers is 'clearly'shown in V Fig. .3 and when the bomb is thrown the im pact caused by striking tends to displacethe inner shell relatively to the outer shell to the position shown in Fig. 45. The camrning action of the shoulders produced by the depressions 19 in the outer shellon therounded heads of the locking pins, forces them "inwardlymoving the lugs 18" out" of engagement with the triggers which are then moved into engagement with thepriiners by the force or" the actuating sprlngs 13.' Means are provided for preventing premature ac tuation of the locking pins 17. Forthis radial opening 19? leading to a point adjacent the middle of the sleeve 6. The sleeve v6 is provided also witha recess communicatingwith the opening 19* in the shell and also'with the central recess in .the sleeve. Seated within this opening in-the shellan'd slidablymovable therein is asafety locking pin'2l which when moved inwardly to its full extent has its inner end projectedbef controlled by the relative movementof said 1 spaced members for releasing said locking Jmeans and permitting said firing device to tween the inner ends otthe locking pins 17 and positively prevents any actuation or movement of the locking pins such aswould The pin 21 projects through an opening in the wallet the outer shell where it isprovided with a shoulder The locking pins liare, then '22 engaging its outer wall and terminating against the outer wall of the outer shell.

The spring 28 operates to automatically withdraw the pin 21 when the same is released from its retaining devices. Formed on the outer shell on opposite sides of the opening through which the pin 21 is inserted is a pair of ears 24; and 25. The ear 25 is provided with an opening'which receives a pint26 and a strap .27 of sheet metal or other suitablematerial has a bifurcated end 28 engaging the pin 26- and extends over and engages the outer endof the pin21 and r then extendsto a point in'contact with the outer wall of the sh'ell'l where it is-provided with an opening through'which the car 24 extends. cotter pin 29 or other suit- 1 able means may extend through an opening in the ear 24: to secure the strap 27 1n position onthe shell; With the-parts in the posi' tion' shown in "Fig. 3, the bomb is secure against accidental explosion and can be safely handled and transported from place to p'lace without, danger'o'f accidental explosionu. In preparing the; bomb for use it is only necessary to withdraw thecotter pin 29 when the expansion of the spring; 23
