CONSTRUCTION OF SHIPS OR OTHER VESSELS.

SPECIFICATION forming part of Letters Patent No. 429,291, dated June 3, 1890.

Application filed April 5 1890. Serial No. 346,753. (No model.)

To all whom it may concern.-

Be it known that I, SINCLAIR STUART, of-

Plainfi'eld, in the county of Union and State of New Jersey, have invented a new and useful Improvement in the Construction of Ships and other Vessels, of which the following is a specification, reference being had to the accompanying drawings. I

This invention relates to vessels constructed entirely of iron or of steel and to what are known as composite vessels, constructed partly of iron and partly of steel or partly of iron or steel and partly of wood. Its object is to build vessels of great strength in proportion to the weight of material employed in them and to simplify their construction; and to this end it consists in the construction of the frames of such vessels, as hereinafter described, of channel-iron, whereby such iron is made to constitute both main and reverse frames, and also the floor-plates, and separate floor-plates may be dispensed with.

Figure 1 represents a transverse section of parts of one side and of the bottom of the vessel and showing a front View of the frame illustrating my invention. Fig. 1* is a view corresponding with Fig. 1 of a portion of the frame to be hereinafter explained. Fig. 2represents a transverse section of the frame in the line a: a: of Fig. 1. Fig. 3 represents a transverse section in the liney 'y of Fig. 1 as viewed from the right. Fig. 4representsatransverse section in the linez z of Fig. 1. Fig. 5 represents a section corresponding with Fig. 40f a modification of the lower part of the frame. Fig. 6 represents a section in the line f of Fig. 1. Fig. 7 is a front view of part of the frame, exhibiting a modification of the construction shown in Fig. 1. Figs. 1, 1*, and 7 are on the same scale. The other figures are on a scale four times that of Figs. 1 and 7.

Similar letters of reference designate corresponding parts in all the figures.

A designates a broad channel-iron set up edgewise, arranged with its length transverse to the vessel and with its web vertical and its flanges a presented in the direction of the length of the vessel. This channel-iron has its web of ,a width or depth several times greater than the width of its flanges, its purpose being to serve as a main and a reverse frame and an upright floor in the bottom of the vessel. This channel-iron, which may be made in as many lengths as may be desired, according to the beam of the vessel, extends through the bottom of the vessel to the turn of the bilge thereof.

B designates a much narrower channel-iron, which is united with the broader channel-iron A. This narrower channel-iron B has its flanges presented in the same direction as the flanges of A. It constitutes the main and reverse frame in the sides and bilge of the vessel. As shown in Fig. 1*, and also shown in Fig. 1 in dotted outline, the lower part of the said-channel-iron,which comes in the bilge of the vessel, is split and bifurcated and spread, so that its flanges b may meet and conform to the flanges a of the broader channel-iron A, as shown in Fig. 1.

As shown in Figs. 1 and 3, the space between the flanges 12 of the divided and bifurcated portion of the channeliron B is filled by a margin-plate O, which is riveted, as shown at c, to the bifurcated portions of the said channel-iron B. At the meeting of the ends of the broader channel-iron A and the divided ends of the narrower channel-iron B an angle-iron e is riveted, as shown in Figs. 1 and 6, across the web of the channel-iron A, and a similar angle-iron e is riveted, as shown in the same figures, to the divided portionsof the chaunel-iron B,and these two angle-irons c e abut together and are riveted together, as shown at f in Figs. 3 and 6. By this mode of uniting the broader and narrower channel-irons great stiffness is given to the frame at the turn of the bilge of the vessel.

In Figs. 3 aud t there is shown riveted along the upper and inner edgeof the unflanged side of the channel-irons A and B an angle-iron D, which serves'as an additional reverse frame for such parts of the vessel in which a double reverse frame is required. In other portions of the vessel this angle-iron may be omitted.

In the modification of my invention shown in Fig. 7 the narrower channel-iron B is not divided, but is continued intact through the bilge to the broader channel-iron A, the lower flanges of the two channel-irons meeting and conforming to each other. In this modification the margin-plate O is used, and its upper edge is broadened in curved form from the upper turn of the bilge to meet .the upper edge of the channel-iron A, and an angle-iron Gis riveted to the upper edge of the said marginplate to form a continuation of the reverse frame from the floor through the bilge to the side of the vessel.

WVhat I claim as my invention, and desire to secure by Letters Patent, is

1. The combination, in the frame of a ship or other vessel, of united broader and narrower channel-irons, the broader channel-irons being arranged in the floor of the vessel and therein constituting main and reverse frames and floor-plates, and the narrower channeliron being arranged in the sides and bilge'of the vessel and therein constituting main and reverse frames, and being continued through the bilge and connected with the broader channel-iron, substantially as herein set forth.

2. The combination, in the frame of a ship or other vessel, of united broader and narrower channel-irons, the broader channel-iron being arranged in the fioor of the vessel and therein constituting main and reverse frames and floor-plates, and the narrower channeliron being arranged in the sides and bilge of the vessel and therein constituting main and reverse frames, and being divided and bifurcated in the bilge, and having its lower ends spread to make their flanges conform to the flanges of the broader channeliron at the point of meeting of said flan ges, substantially as and for the purpose herein set forth.

3. The combination of the broader channeliron A, the narrower channel-iron B, divided, bifurcated, and spread to conform to the said broader channel-iron, the margin-plate G, riveted to the said narrower channel-iron, and the abutting angle-irons e e, riveted to said broader and narrower channel-irons, to said margin-plate, and to each other, substantially as herein set forth.

4. The combination, in the frame of a ship or other vessel, of a channel-iron constituting a main and reverse frame and a floor-plate and an an gle-iron riveted along the upper edge of said channel-iron to make a double reverse frame, substantially as and for the purpose heroin set forth.

SINCLAIR STUART.
