To aZZw/wm it ma concern Be it knownthat I, WILLIAM L. MARTIN, a citizen of theUnited States, residing at Boyne City, in the county of Charlevoix and State of Michigan, have invented new and useful Improvements in shields for the Pro tection' of Ships, of which thefollowing is a specification T My invention relates designed as a shield or aguard forthe protection of ships and other boats or vessels from destruction by torpedoes firedfrom submarines, r

-Th main object of this invention is to 2 0 7 vide a fioating boomiwith aprotectingshield v coupled together and securedto the side of provide simple,- practical and eflicient means suitably secured to the sides ofasliip or other boat, inorderto arrest a torpedo, and prevent'its contact with the body or hull of the vessel.

Another object ofthe invention is to -prosecured thereto, said'shield depending a sufficient distance below the hoom'and from the sides of a ship to properlyprotect the hull of'the ship, and built in sections suitably the ship by means of a bracket or arms hinged to the top of the boom, whereby the shield is held or retained at a suitable distance from the side of the ship to-prevent its pounding or contact with the sides thereof, the whole adapted'to' be towed by a line'or 7 cable suitably secured to the bow ofthe ship.

A further -object ofmy invention is to furnish a novelmeans of protecting ships from destruction by torpedoes, by utilization of a fioat witha shield secured toand suspended from said float, designed to be coupled together in a string or train, suitably attached to the side of thesh'ip with an arm or bracket and drawn-or towed by a cable, adapted to be used to advantage in the shorterruns in the danger zone, 'andit may be :used in longer or more extended runs outside of the danger zone.

The foregoing and such other objects as may appear from the ensuing description are attained by the combination, construction and arrangement of the parts hereinafter more fully described and illustrated in p the accompanying drawings, and particularly pointed out in the claims appended hereto, it being understood that slight changes in the preciseform and construction may be resorted to without departing "from the spirit or sac p Specification of Letters Patent.

rificing any of the advantages of the lnventlon.

In the accompanying drawings which form a part of the specification it will be seen that i Figure l, is a side elevation of the deviceembodylng my invention, showing it applied to theside of a ship orother vessel. to a device especially device showing it attached to one the hull of theship or vessel:

Fig. 2, is a transverse sectional view of the side of Fig.3, is aside elevatioii-of one of the shields secured to the float and detached ployed to designate corresponding parts throughout the several figures of the drawings. 1 i

, ln' carrying out my invention the device is shownas applied to only one side of thehull vessel, and l the bracket arms "pivotally and .removably secured in 1 any suitable manner to said hull above the water line, theinner end 2, of each arm being preferablysecured to anieye bolt3," firmly secured to the hull sothat the bracket may be swung in an up .ward and inward direction when desired, the outer ends 4:, of the bracketarm's being suitably hinged at 5 to a hollow metallic preferably somewhat spherical, and made of sheet steel, which if desired,ma'y be strengthened by cross rods or a light frame secured within the float. The top portion of the float is provided with an angle iron 7, for strengthening and stifi'ening said portion, and to the bottom portion 8 of the float a shield 9 is suitably secured and suspended therefrom to a sufficient distance below the water line to protect the hull from contact with submarine torpedoes and preferably consists of a series of steel bars or plates 10, or wood slats covered with steel, suitably secured to each other and. to the bottom. porof a ship, butit will be understood that it inaiy be secured to either or both sides of the hul.

A-designatestheihull of a ship or other float 6 of any suitable .orl desirable shape,

tion'of the'float by fienible wire cables 11',

thereby forminga flexible shield, andthe front and rear end portion of each "sideof each float is flattened at 12 for thepurpose of reducing their resistance while being towed along with the ship. V

It will be understood that these shields are built in sections, each provided with and securedto a float, and are coupled together in any suitable manner, in a line or like a train of cars from the bow to the stern of the ship, and to-the foremost float the front end portion 13, is provided with an angle iron 14, adapted to strengthen andstifl'en the same,to which angle iron 14: is suitably secured a towing cable '15, the latter being secured inany suitable manner to the bow of the ship, whereby the series of shields of plates or barslO by coupled together may be readily towed along I with the movement of the ship.' 7

The wire cable 11, is secured to the series such like equivalent 16.

' claim and desire to secure by Letters-Pat- It: will be readily perceived that the bracket arms may be, provided with means secured thereto whereby the said arms may be swung upward and inward so that when desired the shields may be raised and adjusted to rest against the side of the ship, substantially above the water line. i

Having described my invention, what I i a ship, metallic floatsprovided with a reincomprising 'a' plurality of bracket arms,

forced upper portion to which each end of each bracket arm is 'hingedlysecured, a shield composedrof a seriesof horizontally V 7 arranged slats flexiblyfsecured together and suspended 'fromthe bottom portion o'feach float, and a towing cable secured tothe front end of the foremost float and .tothe bow of theship. 1 j device of the character, described each of said bracket arms being pivotally secured intermediate its length to the hull of means of staples or :a ship,aplurality of hollow metallic floats each having; a reinforced upper portion to V which" each end" of jeach bracket arm 1s ries of horizontally disposed slats suspended from the .bottomportionof each'Qfloa-t, aplura'lity of perpendicularly disposed; flexible means-for,securing the said slats together,

a-nd'a towing cable s'ecured'to' the front end of the foremost float and the boW of the ship.

comprising a "pluralitygof bracket arms, each of said bracketarms being'pivotally ,each float having an angle iron reinforcement at its upper portion to wlnch'eachend 6'0 3. A device of the character describedof each bracket arm ishingedlv connectech'n a shield composed of a series of horizontally; disposed slats suspended from the bottom V ofeachfloat, a plurality of perpendicularly disposed flexible wire cables for-"flexiblyse curing said slats together, and a towing cable secured to the front end ofthe fore-x most float andthe bow of the ship.

4. A device'rofv he character described comprising a plurality1of bracket arms, each of said bracket arms being pivotally secured intermediate itslengthtothe hull of:

fa ship, a plurality of .metallic' floats having any angle ironi reinforcement at the upper arm is hingedly connected, each: float having shield composed of a seriesofhorizontally pluralityl of perpendicularly disposed flez'zi portion towhich eachend'of each bracket blewire cables connecting'each of the slats together, and a towing cable connected to the-front endof theforemostjfloat and the bowof theship. .7 o i i In testimony whereof I havehereunto set my hand in presence of two subscribing witne'sses.
