MARINE HULL.

SPECIFICATION forming part of Letters Patent No. 769,502, dated September 6, 1904.

Application filed March 18, 1904.

T (til whom, it may concern:

Be it known that I, THOMAS H. SMITH, a citizen of the United States, and a resident of Sturgeon Bay, in the county of Door and State of Visconsin, have invented a new and Improved Marine Hull, of which the following is a full, clear, and exact description.

This invention relates particularly to the construction of boats, launches, and other smaller craft; but it is applicable broadly to the construction of marine hulls of all types.

The invention consists in an improved manner of constructing metallic hulls, and it lies particularly in the means for fastening the metallic sheathing to the frame, in the manner of joining the sheathing-plates to each other, and in novel means for stiffening the entire structure.

This specification is an exact description of one example of my invention,while the claims define the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both the views.

Figure 1 is a side elevation showing as an example a sailing-hull constructed according to my invention, and Fig. 2 is an enlarged cross-section of the same.

It indicates the keel, and Z) the ribs orframes, all of which are preferably constructed of wood.

0 indicates the metallic sheathing, which preferably consists of galvanized sheetiron.

Running fore and aft along the outer sides of the frames b are iron beads (Z, which have rounding outer surfaces and which are arranged one at the lower edge of each strip of sheathing 0. These beads (I cover the lower edges of the sheathing-strips and are fastened securely in place by screws 0, which pass through the metal beads and sheathing and into the ribs or frames, as shown. The upper edge portion of each sheathing-section e is curved to extend over the respective beads (Z, as indicated at c, and the extreme upper edges of the sheathing-sections are formed with hooks which are engaged under the strips or beads (Z and soldered securely to the sheathing-section above it.

Said curved por- Serial No. 198,708. 1N0 model.)

tions 0 of the sheathing-sections therefore serve to inclose and protect the metal beads (Z, and by soldering the parts 1: to the contiguous sheathing-strip an absolutely hermetic structure is obtained. If desired, the uppermost bead (Z may be made considerably larger than the other beads, so as to form a chafing bead or guard, as indicated in Fig. 2. The sheathing-sections may be joined to the keel and to the sheer-strakes of the boat in any desired manner.

This construction provides for cheaply constructing a boat and at the same time for producing a hermetic and an extremely stiff and durable. metallic hull. The beads w, running fore and aft along the boat, greatly stiffen the same and avoid the danger commonly encountered in connection with metallic boats-to wit, the frequent and severe indentation of the light sheet metal constituting the sheathing thereof.

Various changes in the form, proportions, and minor details of my invention may be resorted to at will without departing from the spirit and scope thereof. Hence I consider myself entitled to all such variations as may lie within the intent of my claims.

Having thus described my invention, I claim as new and d csire to secure by Letters Patent- 1. A marine hull, comprising ribs, beads extending fore and aft along the outer sides thereof, and metallic sheathing-scctions, one edge of each section lying under the bead adjacent thereto, and the other edge portions of the sheathing-sections extendingover the ad jacent beads.

2. A marine hull, comprising ribs, metallic sheathing-sections lying on the outer sides thereof, beads located over one edge of each section, and means extending through the beads into the ribs to fasten the beads and sheathing in place, the other edges of the sheathing-sections being passed over the beads and secured to the adjacent sheathing-section.

3. A marine hull, comprising ribs, sheathing-sections lying outside thereof, and beads secured to the ribs and engaged with the edges of the sheathing-sections to hold them in place.

4. A marine hull comprising a framework, metallic sheathing-sections, and a series of framework to fasten the beads and sheathing in place, the other edge portions of the sheathing-sections being curved to extend over the beads and each of said portions having a hook at the extreme edge extending under the bead and secured to the adjacent sheathing-section;

In testimony whereof I have signedmy name to this specification in the presence of two subscribing Witnesses.

THOMAS H. SMITH.
