Patented Jan. 21, 1939 GREGORIO SGAGLIA, or TURIN, ITALY, assrenon T SOOIETA ITALIANA nanns'ro BBIEDA, OF MILAN, ITALY BOMB Application filed Au ust'm', 1928, Serial no. 302,338, and in- Germany new 7, 192%.

This invention has for its object a bomb adapted to be thrown by hand or by means of fire arms.

In known bombs of this class it happens that when the bomb strikes by its bottom a soft ground and enters the same, its ignition device does not operate and then the bomb is ineffective.

The bomb according to the present invention comprises an ignition device by which the liability to ineffective operation is removed.

On the annexed drawing are shown by way of example two embodiments of the bomb according to the present invention and:

Figure 1 is a central section of a construction;

Figure 2 is a top view, and

Figure 3 is a central section of a modified construction.

In the construction of Figure 1, the bomb comprises a casing consisting of a shell 1 having an inverted cup 2 fastened on its mouth, say by screwing; said cup 2 is shaped to a portion of a sphere with centre at O and has an orifice 3 lying on the axis of the assembled elongated casing 1-2.

In said orifice 3 is located a sleeve 4 having two concentric flanges 5-5 which pro vide an annular groove 6 entered by the edge of the cup 2 encircling its opening 3.

Flanges 55 are shaped to a sphere with centre at O and the orifice 3 of cup 2 has such a size and extent as to permit the sleeve 4 of floating in any angular direction around said centre 0.

In the shell 1 is freely located a mass consisting of a jacket 7 containing an explosive charge 8 and said jacket has a rounded bottom 7 which bears on'tapering bottom 1 of shell 1; said mass also has a central bore 9.

In sleeve 4 is mounted to slide a barrel 10 having a collar 11 abutting on the edge of sleeve 4; said barrel 1O enters bore 9 of mass 7--8 and its top portion adjacent sleeve 4 contains a striker 12.'

In bore 9 of mass 7 8 is located a container 13 which encloses a primer 14 and a detonator 15, said primer being opposite the striker 12;

6% container 13 leaves an annular gap between it and the surface of bore 9 of mass 7-8 and has a bottom outstanding flange 13.

Barrel 10 enters bore 9 and encircles said container 13 and a spring 16 is located intermediate the edge of barrel 10 and flange 13.

A protecting cover 17 is fastened on cup 2 over sleeve 4 and cooperating parts and a removable hood 18 is inserted over cover 17, said hood 18 being hinged with a transverse safety bar 19 which extends through registering holes of cup 2 and barrel 10, said bar lying intermediate striker 12 and primer 14.

A removable safety pin 20 having a finger ring 21 is inserted through hood 18 and cover 17 At the time the bomb is to be thrown, the safety pin 20 is removed by means of its finger ring 21, and the bomb is thrown either by hand or by any suitable means, as a fire arm provided with a suitable enlarged barrel, or a trench-gun, or the like.

During the fly, the hood 18 is reversed and under effect of resistance of air it drops down from the bomb, the safety bar 19 being thus removed by said hood.

At the time of impact, if the bomb strikes an obstacle by its bottom 1, the barrel 10 and striker 12 move by inertia towards primer 14 which is thus fired and then fires the det' onator 15 and the explosive charge 8.

Should impact occur in register with cover 17, then mass 78 moves towards the striker and the primer 1.4 is fired.

Finally should impact occur on the side portion of the shell 1, the assembly of mass 7-8, barrel 10 telescoping therein and sleeve 4 are moved angularly around centre 0 of the floating coupling provided by flanges 55 of sleeve 4 and cup 2 and then the mass 78 is caused to approach the striker 12 owing to the tapering shape of bottom 1 of easing 1 on which the bottom portion 7 of mass 78 is caused to more.

Spring 16 provides for the approach of parts 78 and 1012 at the time of impact while holding said parts spaced from each other during the fly, after removal of bar 19.

As a modification the flange or collar 11 of barrel 10 could be omitted, the striker-carrying head of barrel 10 being then arranged to slidingly abut on the cup 2.

Figure 3 shows a modification in which the floating motion of barrel 10 is secured by a ball head 22 shaped to a sphere with centre at 0 which seats in a concentric spherical por tion 2 of cup 2; said head 22 is secured on the top of the barrel 10 carrying the striker 12 by means of a sleeve 23 encircling barrel 10 and has a rounded rim 24 which is intended to bear on the surface of cup 2 and to guide the parts in their floating motion.

The use and the operation of this construcion are thesame as those described in connection with the construction of Figures 1 and 2. r r
