Application May 3, 1939, Serial No. 271,557
2 Claims.
This invention relates to a hull construction of a boat, and has for the primary object the provision of a construction .of the above stated character which may be easily and quickly constructed 5 and which will provide maximum strength and durability and will be extremely simple to assemble and may be manufactured at a low cost.
With these and other objects in view, the invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.
For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings, in which Figure 1 is a side elevation, partly broken away, illustrating a boat in which the hull thereof is constructed in accordance with the present invention.
Figure 2 is a top plan view, partly in section, illustrating the same. 7
Figure 3 is a transverse sectional view taken on the line 3-3' of Figure 2.
Figure 4 is a fragmentary longitudinal sectional view taken on the line 4-4 of Figure 2.
Figure 5 is a fragmentary perspective view showing the joining of a longitudinal and vertical member employed in the construction of the hull.
Referring in detail to the drawings, the numeral 5 indicates the hull of a boat, the particular design of which is non-essential as far as the present invention is concerned. The cabin or upper structure of the hull is indicated by the character 6 and does not form a part of the present invention.
The hull 5 includes a hollow keel as indicated at I which will act as a shaft log for the propeller shaft, the latter being indicated by the character 8. In constructing the keel I a pair of channel iron members 9 are arranged a selected distance apart having the flanges thereof extending in opposite directions. The members 9 are held against relative movement by inner and outer plates I and II which go to make up the wall construction of the hull. It is to be understood that the keel extends from the stern of the hull to the stem thereof.
Extending in opposite directions from the keel are metallic members I2 constructed of half round stock and including horizontal portions and vertically arranged portions. The horizontal and vertical portions go to make up the ribs of the hull. The members I2 are welded onto the channel iron members 9 that go to construct the keel I. The members l2 are spaced a selected distance apart and have secured thereto longitudinally extending and relatively spaced members I3 constructed of half round stock. The flattened faces of the members I2 and I3 are brought together and are welded to each other. The longitudinally extending members I3 extend from the stem of the hull to the stern thereof and coact with the. members I2 in forming an extremely durable and rigid construction.
The bottom and side walls of the hull are con- 10 structed of metallic plates Welded onto the longitudinally extending members I3 and are indicated by the character I4. The seams between the plates I4 are closed by welding. The inner wall construction, indicated by the character I0, is composed .of metallic plates arranged horizontally and vertically, the vertical plates being indicated by the character I5 and are welded onto the horizontal plates the latter being welded onto the members I2. The vertical plates I5 are spaced a distance from the vertical portions of the members I2 and coact with the outer plates and decking plates I6 in forming watertight compartments. It isto be understood that the verti' cal plates I5 and the horizontally arranged deck ing plates are welded together, the decking plates also being welded to the upper edges of the outer plates I4.
To aid in supporting the vertical plates I5 horizontal and diagonally arranged braces I1 and I8 are welded onto the vertical plates and to the vertical portions of the members I2 and also welded to each other. Thus it will be seen that an extremely rigid and durable frame construction is provided for the hull having a hollow keel construction to provide a shaft log and may have the inner and outer wall plates readily welded thereto which coact with the members of the frame construction in preventing undue weaving of the hull in rough water. I
As shown in Figure 4 the stern of the hull may be of the overhanging type and the decking plates I9 thereof besides being welded onto the inner and outer wall plates may also be welded onto an angle iron brace 20 extending between opposite walls of the hull.
It is believed that the foregoing description, when taken in connection with the drawings will fully set forth the construction and advantages of this invention to those skilled in the art to which a device relates so that further description will not be required.
Having thus described my invention, what I claim is:
1. A metallic boat hull comprising relatively spaced longitudinally extending metallic members of channel iron construction providing a keel, relatively spaced transversely extending metallic members of half round stock welded on said first members and including horizontal and vertical portions, longitudinally extending metallic members of half round stock welded on said vertical and horizontal portions of said second members, outer metallic plates welded onto said longitudinally extending members and having the adjacent edges thereof welded together to form the bottom and outer side walls, horizontally and vertically arranged inner wall plates welded to each other with the horizontal plates resting on and welded to the horizontal portions of the thirdmentioned members, and metallic decking plates welded onto the upper edges of the vertical wall plates and the outer wall plates.
2. A metallic boat hull comprising relatively spaced longitudinally extending metallic members welded to the horizontal portions of the third' mentioned members, metallic decking plates welded onto the upper edges of the vertical wall plates and the outer wall plates, horizontally and diagonally arranged braces welded onto the sec-- ond members and the inner vertical 'wall plates.
