Specification of Letters Patent.

Patented Feb. 29, 1916.

Y Application filed April 14, 1915. Serial No. 21,206.

To all whom t may concern Be it known that I, HENRY W. JACOBS, a

citizen of the United States, residing at' Topeka, in the county of Shawnee and State of Kansas, have invented certain new and useful Improvements inY Boats, of which the following is a description, reference being had to the accompanying drawings, which form a part of my specification.

My invention relates more particularly to the hulls or shells of submarine boats constructed of metal; having for its object the provision of a double walled construction possessing increased strength without, however, increasing the weight. By yreason of the construction, comprising inner and outer walls, reinforced bers or portions, chambers or cells are provided, which may be utilized for the storage of air and fuel; suitable mechanism being employed for properly controlling and directing such supplies.

AY further object of the invention is to provide a construction whereby the possibilv ity of leakage will be practically eliminated owing to the method of construction whereby greatly improved Joints are provided, and

the safety of the construction materially increased. Y

Another object of the invention is to provide a construction which not only possesses greater strength without increased weight, but which may be produced at less cost, comparatively, per unit weight.

The invention possesses other advantages inherent in the construction, which will be apparent from the following detailed de! scription. Y

In the drawings: Figure l is a partial side view, in perspective with portions ofthe walls broken away and the reinforcing v members shown in section, in order to more clearly disclose the general construction. Fig. 2 is a cross-sectional view taken on the line A-B o-f Fig. 1. Fig. 3 is a cross-sec tional view taken on the line C-D of Fig. 2.

In the particularexemplification of my invention, as illustrated in the drawings,

wherein the invention relates more especially to the shell or hull of a submarine boat, the

boat is provided with outer and inner` walls, as indicated at 5 and 6, respectively, which are composed of flanged sections extending circumferentially; the sections being of any suitable cross sectional contour, with thev or stayed by suitable mem-` sides or flange-portions ofthe sections preferably disposed. inwardly. In the construction, as illustrated, the outer wall 5 consists of a series of sections 7, see Figs. 1 and 3, illustrated in the nature of channels; the sections being placed adjacent one another so that the sides or flange- portions 8, 8 of the various sections will be arranged parallel with each other and extend circumferentially about the boat, as shown in Fig. 1; the flanges or sides 8 being preferably presented inwardly as shown. The inner wall 6 is also preferably constructed of channels 9, of smaller circumference, having the sides or flange- portions 10, 10 also preferably presented inwardly, where they may be accessible for the purpose of securing them together, and arranged to extend circumfer entially, as shown in Fig. 1.

In order to not only maintain the relative position or spaced relation of the outer and inner walls, but also to properly reinforce the walls, I provide reinforcing members or stay-sheets 11 having the cut-out circular portion or central opening, as shown at 12 in Fig. 2, in order that a continuous chamber or passage may be provided within the inner wall. The reinforcing members or stay-sheets 11 are Yadapted to be inserted be tween the adjacent sections of the construction, namely between the sides or flanges 8, 8 of the sections constituting the outer wall 5 and the flanges 10, 10 of the sections constituting the inner wall 6; the stay-sheets or reinforcing members 11 and the abutting flanges 8, 8 and 10, 10 being secured together as, for example, by a suitable numberof rivets, as indicated at 13, which are intended to extend entirely through the adjacent iianges and the stay-sheet, as morel clearly shown in Fig. 3.

In Fig. l, portions of the outer wall 5 and of vinner wall 6 are broken away in order to more clearly illustrate the method of arranging the respective sections constituting the two walls, as well as the method of placing the intervening members or stay-'sheets 11.

In order to provide a suitable deck-portion for the outer wall 5, the upper parts of the intervening members or stay-sheets 11 are somewhat flared or extended, as shown at 11a, see Fig. l, while the intermediate upper portion of each reinforcing member orstay-sheet v11- is preferably extended upwardly, as shown at 11b, and the upper parts of sections 7, constituting the outer wall 5, are likewise made to conform to the formations of the reinforcing members 11 at their tops, in order to provide the flat horizontally disposed deck-portions, as shown at 14, l5

firmly united together by welding; for cxample, the portions of the sections, which constitute the lower or rounded part of the hull, may be made of one piece, while the part of each section, which forms the top, as indicated at 14, 15 and 16, may beV of a single piece, with the abutting ends of the lower and upper portions of each section properly welded togetheigvthus practically providing an integral wall. j.

In assemblingthe various parts, the reinforcing members or stay-sheets 11 are first securely riveted 0r otherwise properly securedv between the flanges 8, 8 of adjacent sections 7, constituting vthe outer wall 5, after which the sections 9, constituting the inner wall 6, are riveted or otherwise cured to the Aintervening stay-sheets.

It is .evident that the employment of a series of sections, circumferentially arranged, with the intervening stay-sheets extending from thekouter to the inner wall, re-

sults in a number of bulk-heads or separate chambers being formed extending circumferentially and arranged thro-ughout the entire -length of the boat, as can clearly be seen in Figs. 1 and 2. As these chambers extend entirely about the inner wall G, injury to the outer1 wall 5 would not necessarily result in injury to the inner wall.

The yconstruction of a series of circumferentially extending chambers arranged side by side throughout the length of the boat, made fluid tight, provides space for the separate storage of air and oil; proper connections from the interior of the boatl with the various chambers being, o-f course, provided to enable the utilization of said supplies, ,as well as the displacement of the air in certain chambers by water or other suitable ballast employed for the submersion of the boat. As the various mechanisms necessary for manipulating the matter within ythe chambers mayv be similar to those at present in use, which mechanisms form no part of my present invention, a detailed description of the sameand the connections necessary need not be `entered into.

The boat may be given any suitable contour and tapered toward the ends as is usual, if preferred; while the decloportion would, of course, be provided with a conning tower and other parts usual on submarines or sub-y mersible boats.

The employment of a series of channel sections, -havingtheir flanges or angular sides arranged parallel, provides a series of circumferential ribs which are reinforced by the stay-sheets between each set of flanges, with the result that a construction capable of withstanding great water-pressure vis provided, which, therefore,V is capable of submersion to a considerable depth.

Aproper riveting' of the flanges and intervening stay-sheets or reinforcing members will obviate any possiblity for leakage, so that my improved construction possesses greater safety than is true with constructions heretofore employed. It is also evident from the construction that if one or more of the sections become injured in any manner, such section, or sections, may be readily replaced by simply removing the rivets, whereby the respective flanges of adjacent sections and the intervening staysheets are held together and replacing the injured section, or sections, by riveting saidA section, or sections, in the manner herein shown and described.

I have shown and described what I believe to be the simplest and best form of my invention, vbut the same may be altered in certain respects without, however, departing from the spirit of my invention, and Ido not wish to be understood, therefore, as limiting myself to the exact construction shown and described.

What I claim is l. A boat provided with an inner and an outer wall composedvof series of sheet metal channel sections disposed circumferentially, the flanges of the lchannel sections being disposed inwardly so as to provide inwardly presented ribs, and a single piece stay-sheet having the portion within in the inner wall cut out and arranged between and secured to the flanges of adjacent sections so as to extend transversely of the boat intermediate of the walls and thereby maintain a spaced relation between the walls and provide a series of circumferentially disposed chambers.

2. A submarine including a series of outer channel sections and series of inner channel sections inclosed thereby, both the outer and the inner channel sections being disposed circumferentially about the boat, a stay-sheet between the adjacent sections of both series, and means to fasten the staysheet tothe adjacent, flanges of the channel sections'.A

3.` A boat provided with an inner and an outer wall composed of sheety metal sections arranged transversely and continuously about the boat, the sides of the sections beingk disposed inwardly so as to provide circumferential ribs, stay-sheets arranged between and secured to the inwardly disposed sides of adjacent sections of both walls so as to maintain the walls in spaced Gopies of this patent may be obtained for relation, and means whereby the sides of adjacent sections and the intermediate staysheets are secured together.
