MARINE MUNITION AND THE-LIKE.

Application filed April 12, 1818. Serial No. 228,204.

To all whom it may concern:

Be it known that I, Amomo AUcUs'ro 'BARBOSA, a, citizen of the United States, is

' ,sels, which, will be superior in point of relative' simplicity and inexpensiveness in con str'uc'tion and, organization, taken in connec- @1011 w th facility in use and control, pos1--- tiveness and effectiveness in operation, 'a'nd general efficiency. gl/Yith 'the above and, other ob ects in view, the" invention consists in the novel "and useful provision, applicatlon, construction, combination, association, relative arreligeipentwandnmode of handling and use' n t suc means and its arts; and features, ell as hereinafter described, shown in the drawing and finally pointed out in claims.

. tmtion .ofist esem 'taken upon the line w m Fig. 11, end looking downwardly;

g; 3 is a view-similar to Fig. '1, showing a modified form of construction in tended for a different mode of use, at art being broken away for convenience of i lus- 1g. 4 is e conventional showing of a, submerged submarine craft provided with two of the mines shown in'Fig. 1, said mines being shown-upon an enlarged scale, connections between the mmesand the submurine bein' broken away for conven- :ienejtfiillulstgs ionze- This view also shows a. marine vessel above the mines and about he etti'eked some;

Fig. "-5 is an enlarged detail transverse sectional view taken upon the line mv, Fig. 4; and

Fig. 6 is a view similar to Fig. 4,.of a submarine and mine features therewith, showing the mines being towed by the submarine, parts being broken away for con vcnicnce of illustration.

Corresponding parts in all the figures are designated by the some reference characters, 3

Referring with particularity to the drawing, the improved marine munitions therein shown, in each of the figures in which the some appear, comprises mine A, the same beingprovided in Fig. 3 with firing means a, responsive to contact with a ship or other object and being provided in the niodificationshown in Figs. 1, 2, and t with firing means 6 adapted to be controlled from a point remote from the mine A, as from the lower or main casing member 9 and anupper casing member 10, preferably rounded or dome-shape, and bolted to thelowcr cesing member 9 at co-cn'gaging flanges, as at 11. Within the casing members is provided the explosive charge 12, which is disposed Within an envelop of pliable or plastic or semi-mobile substance, 13, grease of suitable consistency being especially adapted for such use. V

Within the mass of explosive materiel 12',

' and preferably above the zone of'the'flange connection at 1l, is provided eniass "14, of suitable percussive material or fulrninate, inelinite be ng found suitable for such agents- This likewise is disposed within or covered over by 'an, envelop 15 of the. same general character the envelop" I3, 'and preferably of grease. In the form of mine shown in 3, the firing means a coinprise Specification of Letters Patent. Patented Sept. 10, 1918.

- pemlently d i sol I a rged. grease envelops seems to. prevent, such symfiring pins 16 which are slidably mounted in tubes or sleeves 17 preferably detachably applied to the upper mei'nber 10 of the easing, by threaded connections as at 1.8, at openings in such casing member 10, which permit the pins to play lengthwise and to be brought at their inner ends into contact with the percussive material or high explosive l4, such pins being yieldingly withheld slightly the tulminate 14, as by contractile springs if) applied to the pins and wings.

In the form of mine shown in Figs. 1, '3, i and (i, I provide the firing means (1 utilizing an electric spark produced at the fnlminate H by an electric path consisting of circuit wires 20 provided within the cable and suitably insulated apart as at 21, such circuit wires leading to the battery or source of electrical supply 22 controlled by a. suitable switch 23, the. battery and switch being installed, in the particular arrangement and utilization shown in the drawing, upon or in the submarine vessel B.

The mine at its lower member 9 is pret erahly provided with vertical or longitudinal reinforcing flanges 24. which may be joined together by staggered or zigzag cross flanges :25.

I) designates a marine. vessel. such as awaship. beneath which the sul. n'1arine B with itscaptive mines A is located, and which is about to be attacked by the same.

The (.iperation, method of use and advantages of the improvements in marine muni tion's will be readily understood from the foregoing description, takenin connection with the accompanying drawing, and the following statement:

The contact mine shown in Fig. 3 is suitably located and anchored and operates under the same conditions as in ordinary use of such marine mines, andthe inclusion of the fulminate mass 14 and of the explosive mass 12 in plastic or greasy envelops 15 and 13,.causes a highly etficicnt control and application. of the energy released upon fir ing of such charges. The action scans to be to cause a. more'evenly distributed and uniformly directed radiation of the explosive forces. In the use of these mines in proximity to each other, the envelops of plastic substance or grease prevent sympathetic explosionof the mines when it is intended to only'disclnirge one. This is par' tic'ularly useful in the, event that two or more mines are-held captive by asubmarine or other vessel as shown in Figs. 4. and i, and intended to be successively or inde- The use of these ex losions due to concussion.

.m ()I'CQIl'lCiit flanges 24 and 25 serve to relatively strengthen, the lower member 9- oi the casing, and thereby tend to cause the disruption of the casing at its meu'iber 10, whereby the force sion is directed upwardly and laterally rather than directed down\\-'ardl v.
