Application filed Api'il-IS, 1917.- Serial at. 151,574.

To all whom it may concern:

Be it known that I, Josnrn A. S-rnrmlm-rz, a citizenof the United States, and resident of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Submarine-Destroying Bombs,

drawing.

of this invention is'to destroy falling bombs which explode redetermined depth in the The object water or by contact with a submarineat a lessdepth.

. The bombs may be overboard aerial-or other craft after having ar- .:ranged to explode on-reaching a certaina cylindrical bomb,

depth, the explosion being .caused in any suitableway, for examplebya float connected to detonating devices connected to the .;bomb. byfla cable adjustable to any desired -..length.-

In the accompanying drawings, Figure 1 isadiagfammatic view. showing a submarine and bombs at difierent depths inthe water.

Fig. 2 is aside view of a bomb with parts --broken away.

Fig. 3 shows a bomb in axial section.

Fig. 4: is an enlarged axial section-of par t of a detonating device shown also in Fig. 3.

In these figures, Arepresents the body of ments, or sections, wound about the body of the bomb betweenshoulders or flanges F and provided with terminal devices G by which they may at will be connected or disconnected or may any of them be connected to a cable H attached at its .upper end to a float I having an annular upper end of the bomb' whereby the floatis normally held in place like a readily detached cap for thebomb. The bomb carries in its upper portion a detonating rod J to which the cable segment H is attached, the rod working in a bearing which holds it against later-ai'movement. One end of the upper. cable segment is connected to the upper end of the rod H. The rod is divided,

its parts being connected by a device K p which is readily disconnected by a pull upon the rod H. Separation of the rod releases its lower portion, and when so released a spring L causes this portion to strike fulminate M and explode a small detonating charge v Specification of Letters ZPatent.

All the segments .combi d .need

have a length of no more thanhhe' oderatedepth to which submarines safely descend, and aseach bomb contains a large quantity of very powerful explosive, explosion would probably disablea submarine at some distance from the point of explosion.

When the bomb is provided with the firing pin P it is obvious that explosion instantly follows contact of the pin with a submarine U, at any depth whatever.

The various cable segments are preferably provided, near one end of each, with de-' vices V distinguishable to the eye and to the hand so that the depth to which the bomb will descendbefore exploding, may be fixed by using any desired number of the seg ments wound upon the bomb, for connecting the float-to the detonating device at J.

What I claim is: Y r

1. The combination with a bomb adapted to sink inwater, of a float loosely attached to the bomb and initially forming an extension ofits body and a series of connectible cable segments coiled about the bomb, one above the other, each with readily disconbeing connected to the float and another to the detonating devices of the whereby the exposed ends permit as many as de ired of the Wound segments to be eonnefi ed in series to the float. V

2. A bomb normally carrying a flout and provided with connectible cable segments,

'wound about its exterior and. Having their ends exposed and accessible for connecting 1o and disconnectmg them,.a'cal lo connecting the float to one of the segments, and a'firingr pin connected to one of the segments in series with a segment connected to the float.

In testimony whereof I hereunto affix my 15 fi natum- JOSEPH STEINMETZ
