; nvm/Mofo www m- UNITED STATES PETER SANGOFF, OF QUINCY, MASSACHUSETTS.

SHIP-PROTECTOR.

Application filed. July 10, 1918.

To all whom t may concern:

Be it known that I, PETER SANGOFF, a citizen of Russia, residing at Quincy, county of Norfolk, and State of Massachusetts, have invented certain new and useful Improvements in Ship-Protectors, lof which the following is a specification.

This invention relates to improvements in devices for protecting sea-going ships from submarine attacks and has' as one of its principal objects the provision of means whereby a ship may be protected against torpedoes, mines and the like.

Another object is to provide means where* by the ship is also protected against bombs dropping from above.

Further objects are to provide the protecting devices with resilient means of support so that the shock or impact of blows, given either laterally or from above, are absorbed and not transmitted to the ship.

These and other like objects are attained by the novel construction and combination of parts hereinafter described and shown in the accompanying drawings, forming a material part of this specification, and in which Figure 1 is a side elevational view showing a conventional type of ship and the arrangement of protective devices at the sides and over the top thereof.

Fig. 2 is a top plan view of the same.

F ig. 3 is a front elevational view thereof.

Fig. 4 is an enlarged fragmentary transverse sectional view taken through the hull showing one of the side fending elements and its supports.

Fig. 5 is a similar view of the same, but showing a modification in which the fending elements may be stressed with respect to their supports.

Fig. 6 is a fragmentary front view, partially in section of the bomb protector as arranged over the ship.

Fig. 7 is a fragmentary plan view of the same.

Fig. 8 is a fragmentary side elevational view, showing a modified form of bomb protector, and

Fig. 9 is a fragmentary top plan view of the same.

Referring to the drawings, Figs. 1, 2 and 3 show a conventional type of ship 10, provided with all the various paraphernalia Specification of Letters Patent.

and mechanisms used in navigating the same.

Firmly secured to the hull of the ship 10 are brackets 14, the same being arranged at spaced intervals completely around the hull and in rows one above the other.

Extending horizontally outward from the brackets are rods 15, at the outer ends of which are secured armor plates 16, the same being held in position on the rod by collars 17, pinned directly to the rods. These armor plates are pressed outwardly against the collars by the action of coiled compression springs 18, the same being tensioned by the collars 19 also secured rigidly to the rods 15, this construction being clearly evident in Fig. 4 of the drawings.

In the modification shown in Fig. 5, the outer ends of the rods 15 are threaded, as at 20, and encircled by sleeves 22, thereby permitting the sleeves, which are threaded to the rods, to be moved to or from the hull, the sleeves having exterior flanged ends 23 upon which the armor plates 16 are engaged, the armor plates being pressed outward, due to the effect of the coiled compression springs 24, which in themselves can be adjusted, by the nuts 25, threaded on the sleeves 22, this latter arrangment affording means for extending or retracting the armor plates 16 with reference to the hull 10, the armor plates sliding along the sleeves 21 under the impact of a blow, as from a projectile, thus affording an efficient guard against under-sea projectiles.

In order to provide a defense against aerial missiles, such as bombs or the like, which may be dropped from a height by an aeroplane or other aerial carrier, there is arranged contiguous to the gunwale of the ship, a plurality of upright posts 30 along the sides and ends of the ship, the same eX- tending to a considerable height thereabove so as to clear the entire structure of the ship, including the look-out box, the posts being arranged in opposed pairs, and secured to the upper part of the posts are lugs 31 containing eyes in which are secured the outer ends of coiled tension springs 32, the inner ends of the springs being engaged with similar eyes or equivalent openings formed in the cover plates 33, one or more of which may be used in a superposed relation as shown in Figs. 1 and 3..

From the foregoing it will be obvious that7 due to the large area of the plates 33, their construction must be of adequate strength and also be extremely light.

F or this purpose the modification shown in Fig. 9 is considered preferable', the same consisting of bent hangers 35, rigidly secured in the eyes 31, their loiver ends being coiled about rods 36, to which are engaged the edges of a resilient net 38, thereby dispensing with the necessity of the springs 32, the net being of such magnitude as to receive the blow of a bomb or like aerial object and prevent it from dropping through to the deck of the ship, the net causing the bomb either to rebound or to rest quietly upon its surface without doing damage.

It is to be understood that the various devices shown are to be considered only as illustrative and obviously any modification may be made Without departing from the scope of the invention as indicated by the appended claim.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is.

In an aerial bomb protector for ships, the combination With the hull of a ship, of a plurality of vertical posts engaged with the edge of the gunWale of a ship extending above the highest portion of the ships superstructure, a plurality of superposed coverplates, and coiled tension springs for securing said cover-plates to said vertical posts, substantially as described and for the purpose set forth.

In testimony whereof I have affixed my signature this twenty ninth day of June,

PETER SANGOFF.
