Application filed February 26 1916. Serial No. 80,566.,

Fuses, of which the following is a speeifi cation.

The object of my invention is to provide a simple and eiiicient device for detonating the explosive charge of bombs, projectiles, torpedoes, mines or similar devices at given depths below the surface of water or after definite periods of inmiersion.

My device is' simple, easy and inexpensive to manufacture and accurate and ellicient in action.

In the drawings, Figure 1 is a cross section of my device as embodied in a fuse plug of the usual type; Fig. 2 is an end view of my device showing indicator; Fi 3 is a near View of the inside of the needle valve; Fig. 4%. is a section of Fig. l at its center.

Y'To'furtlier describe a form of my invention which Ihave found advantageous, 13 is a cylindrical body of brass or other suitable material which maybe forced into the Well of a fuse plug of the type usually ap plied to projectiles. This cylinder has an enlarged portion 9 at its outer end for the double purpose of adding strengthand g] V- ing a surface for the indicator dial 27. Slidries the indicator 5.

ably "minted in this bodyis an inner body 10 ads ed to slide inside the cylinder 13 but With a high degree of friction. The range of motion of this inner cylinder or body is controlled by a pin 12, secured in the cylinder 13 and projecting into a slot 11 in the inner cylinder 10. By means of a right angle in this slot, the inner cylinder 10 may be turned several degrees and locked. in that position. The pin 12 and the slot 11, with its right angle extension, acting as a, bayonet catcln-well known in the art. The outer extremity of this body 10 is tapered to'incld'se a small chamber 7 g the outside of this extension is threaded and on it revolves check nut 6 and the valve cap 2 which. car- The end of the cylinder 10 is hroughttoa finely tapered point 3, which point projects through a tapered hole 25 in the valve cap 2. The cap 2 and the tapered point 3 thus operate as a'needle valve and moisture entering around the point 3 is conducted into the chamber 7 through the holes 26. The interior end of 'is then plated on Us *viinder 10 is threaded to receive the ary firing device 153. of the outside cylinder 19 contracted at right angles as at 20 and a re' \ard pro= jection 2.1., is threaded or otherwis adapted to receive an tfliiI-QliOl ci in cup *2 I which cap has an opening in is alter. Between the end 'oi the auxiliary iii device 1' ml the annular formed by A 1 .1".) .-.'-f-\-i, or t 1e en su c 0 HM or u; a recess is ounce as at 17, to receive a circular percussion cap-l8.

Having now briefly described the construction of my device, i -r operation is as follows: Into the cavity 7 at the head of the inner cylinder 10, a co1i1 'mund is placed which can be exploded loythe action of water. There are many compounds known. to the chemical art, especially potash combination which will do this. This cavity is then closed by a thin Wad 1i preferably 01" shellached paper which rests on the annular i'he inward end.

the contraction seat formed by the contraction of the chain- I her 7. The chamber 8 is then tilled with black gun-pmvder or other suitable explosive and another \vad 15 is used to close it. The auxiliary firing device 16 is then cured home, holding the wad in place. The wild 23 is then placed over the rear end of the outer cylinder 13 and thecap ""3 secured in place to hold it. The perm on cap seat. the cliainlu. 1S filled with gunpowder or similar explosive and the inner cj-lindZ-n: 10 is then insertedto its proper position where it is held by theinsertion and u isetting oi the pin 1:; 1n the slot 11. The check nut and the valve cap are then putin place and the entire device now carried in the outer cylinder 13, is placed in the cavity of the fuse plug of the usual form or in any position so that its inner end communicates with the main explosive charge 24..

My device is now ieri'ectly safe for storage and transportation. Tihen it isdesirable touse the. same, the interior cylinder 10 is turned so that the pin 12 can slide freely in the longitudinal slot 11 The valye cap 2 is then turned to its proper setting and locked by the check nut When the projectile or mine, hearing this fuseis submerged water in minute quantities passes in between the seat and the point 3 of the needle valve and reaches the explosive charge in the chamber 7 the explosion is thereupon communicated to the charges in He chamber ti acts s a ltmini'ner, cri'lshing the cir percussion cap 18 between it and the anvil 20, formed in the body of the outer l'lTl(iQl.' 133. The explosion of this percus m ea}: con nunicated to the explosive in l9, mie'ce dotonating the maiden:-

' in the usual manner.

he form of this device may neee sary to adapt it to mines, sublines, bombs, proiectiles and other of LXPlOSlVG implement. aring; thus briefly described the operaoi' an improved form of my device, I
