Patented July 6, 1943 UNITED STATES PATENT OFFICE SHIP GUARD Louis Simeone, San Jose, Calif.
Application October 14, 1942, Serial No. 462,047
The present invention relates particularly to means for preventing destruction of a ship through the impact of a torpedo.
It is one object of the invention to provide a unit that may be duplicated as many times as necessary to completely encircl the inner surface of a ships bottom; one that may be altered in shape and construction to adapt it to any particular location; and one that will elfectually limit the destructive efiects of a torpedo exploding within the confines of the ship.
Another object of the invention is to provide means disposed on the exterior of the ship to engage a torpedo and reduce or destroy its efficiency.
Finally, it is an object of the invention to provide means of the character indicated that may be made in any siz or form desired; that may be economically constructed and applied; that will be strong, durable, and highly eflicie'nt in its practical application.
In the drawing:
Figure 1 is an inside elevation of the unit with the inside plates and filling removed.
Figure 2 is a sectional view on line 2-2 of Fig ure 1.
Figure 3 is a section on line 33, Figure 1.
Figure 4 is an isometric perspective view of one element of a unit.
Figure 5 is an isometric perspective view of a closure between two elements.
Figure 6 is an elevation of a portion of the outside feature of the device.
In the particular embodiment of the device disclosed I show at l a section through a portion of a ships side wall with outwardly directed pins and brackets as 2 and 3 mounted thereon. On the pins and brackets 2-3 is mounted a heavy metal screen as 4, and this screen is held in spaced relation to the side of the ship by springs 5. This screen is placed below the water line indicated at 6.
On the inside of the ships side I and opposite to the screen 4 is mounted a rectangular receptacle 1 open on its front and top and having spacing elements 8 and 9 mounted on its bottom and back respectively, and directed inwardly as shown.
At I0 is shown an arcuate sheet of metal having spacing elements as H mounted on its three sides, its top being open. These spacing elements H cooperate with the spacing elements 8 and 9 to support the member ID a fixed distance from the receptacle 1, and forming a chamber l2 therebetween.
The member I3 is shaped the same as member ID but is smaller in proportions, and is open on top, but has spacing elements 14 mounted on its back to support it in spaced relation to the memher It] in which it is placed as shown.
The member I 5 is still smaller and is shaped similarly to member [3 and has spacing elements [6 mounted on its back to support it in spaced relation to the member l3 in which it is placed, and it is also open on top.
On the inner side edges of member l5 are placed lugs as Hi to which a plate 20 closing the front is secured after which the chamber so formed at 2| is filled with a suitable cushioning material, such as sawdust, asbestos as 22 is placed around its upper edge, and the top member 23 is welded in place.
The chamber 24, between members I 3 and I5, has its front closed by a rectangular sheet-metal element 25, is filled with a cushioning material as 26, the top corners are protected with asbestos and the top 29 welded in place.
The chamber 30, between members l0 and [3, has its front closed by a rectangular element having the shape shown in 25, it is then filled with a suitable cushioning material as 3i, the top corners are protected with asbestos, and the top 32 is welded in place.
The chamber l2, between the receptacle 1 and the member ID, is then closed in front by a member 25, it is then filled with a suitable cushioning material 34, the top corners are protected with asbestos as at 35 and the top 36 is welded in place.
The structure described comprises but a single unit in a single definite shape, but the unit may be varied in shape and proportions to adapt it to any particular position in the ship, and when completed as described the front is covered with a plate as 31.
When a ships hull is protected in the manner described it is expected that the screen 4 will arrest the flight of a torpedo and cause the same to explode on the outside of the ship, butif it does penetrate the hull I it will imbed itself in one of the cushioned chambers 12, 30, 24 or 2|. If the topedo explodes after reaching one of these chambers the result of the explosion will be reduced to a minimum by the cushions surrounding it.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
1. A structure of the character described comprising, a plurality of nested and spaced receptacles mountable on the interior of a ships hull,
tangular receptacle, means operative to support said receptacles in said spaced relationship, closures for all of said recetacles, and a filling of cushioning material for the spaces between said 5 receptacles and filling the smallest receptacle.
