GUSTAF MAGNUSON, OF DENVER, COLORADO.

SHIP CONSTRUCTION.

Application filed October 5, 1918.

To all whom it may concern Be it known that I, GUSTAF MAGNUSON, a citizen of the United States, residin at Denver, in the county of Denver and S tate of Colorado, have invented certain new and useful Improvements in Ship Constructions, of which the following is a specification.

This invention relates to ship construction and'it-s principal object is to provide a ship of simple construction which will meet every requirement of a man-of-war or other sea-going vessel, without the excessive cost and other objectionable features of the present method of building ships.

Another object of the invention is to provide a roof-shaped deck covering that admits of collapse so to be folded away when its use is not desired.

I attain these and other objects, all of which will fully appear in the course of the following description by the constructions and combinations of parts illustrated in the accompanying drawings in the various views of which like parts are similarly designated, and in which Figure 1 represents a transverse section through the hull of a vessel constructed in accordance with my invention, and

Fig. 2, a fragmentary plan View of the same drawn to a smaller scale.

Referring to the drawings by numerical reference characters, the hull of the vessel is composed of two spaced walls 2 and 4: the inner one of which is made of steel or other suitable material and reinforced by an exterior covering 3 of copper plate of a thickness of approximately one inch.

The outer wall 4 of the hull is composed of copper plates of a thickness of approximately six inches and is spaced from the before-described inner wall of the hull with which it is connected by bolts. The space between the two walls of the hull, which is approximately eight inches, is occupied by a filling 5 composed of tightly packed feathers.

The portion of the hull beneath the waterline of the vessel is covered by a layer of cork 6 which at its heaviest part, at the keel of the hull, is about one-foot thick. The cork covering is reinforced by copper plates 7 placed about six inches apart upon its exterior surface, and the different walls, coverings and reinforcing plates are sesurely I fastener-1 together by stay' bolts 8 hereinbefore referred to.

Specification of Letters Patent.

Patented Oct. 21, 1919.

Serial No, 257,000.

The deck of the vessel may be protected from projectiles by a slanting roof 9 which at its ridge is supported upon a horizontal beam 10 which is fastened between the masts 12 of the vessel and which is preferably composed of telescoping sections as shown in Fig. 2 of the drawings. The sides of the roof slope from its ridge toward the "edges of the deck and are composed of a number of ad oining sections each made of lapping plates of copper which are suspended from the before-mentioned beam and supported upon rollers 13.

lVhen the roof is not in use, its sides are removed from the beam and the sections of which they are composed are packed together by sliding them inwardly across the roller 13 and stored upon conveniently placed supports inside the vessel.

The beam 10 may also be removed and reduced in length by driving its telescoping sections together. The adjustment of the roof is facilitated by the use of windlasses 14: upon which are wound a number of ropes or chains 15 which pass around the beam and are attached at the upper edges of the sections of the roof.

The simplicity of construction of a ship built in accordance with my invention, and the absence of costly armor plates and water-proof compartments, greatly reduce the expense of production and make it possible to produce vessels possessing all the characteristics and advantages of the modern man-of-war in less time than is now required to construct even the lightest and most simple vessel for use in the present war and at but a fraction of its cost.

The feather packing which occupies the space between the inner and outer walls of the hull of my improved construction not only offers an effective means for resisting the impact of torpedoes and other projectiles but also increases the buoyancy of the hull in conjunction with the cork covering beneath the water-line.

Having thus described my invention what I claim and desire to secure by Letters- Patent is: 1

1. In ship-construction, the combination with a hull, of a roof-shaped covering above the deck thereof, having retractably supported collapsible sides.

2. In ship-construction, the combination with a hull, of a roof-shaped covering" above the deck thereof, having retractably mp ported collapsible sides and mechanical means to effect their adjustment.

3. In ship-construction, the combination,

with a hull, of a roof-shaped covering above the deck thereof, having retractablv sup ported collapsible sides and a contractible V the deck thereof, having sides movably and openings in the'deckr -5, In ship-construction," the combination with a hull, of a'roof-shaped covering above slidably supported to be retracted through the deck thereof, having collapsible sides movablyandslidably' supported to be retracted through openings of the deck.

In ship construction, the combination with a hull, of a roof-shaped covering above the deck'thereof composed of sectional sides adapted to slide one upon another to admit of the collapse of the covering.

7. Incombination Witha ship having a deck provided with openings at the-sides thereof, adeck roof composed of relatively "movable plates adapted to pass above and beneath the deck through "said openings, beams supported: at an elevation from the deck, and hoistin means passing over said beams for drawmg the roof plates -into' operative position.
