This applicati The present application is a re-filing of application Ser. No. 499,776, filed Aug. 24, 1943, and which has since become abandoned.
This invention relates to new and useful improvements in the construction of ship hulls, and more especially for high speed ship hulls.
Thus one of the main objects of my invention is to obtain reduction of the water resistance to a ship hull, and thereby increase the speed of the ship.
Another object is to eliminate stresses in the hull and to, obtain stiffness in the construction of the latter.
A further object of my invention is to provide a transverse Welding of the plates arranged between the conventional webframes.
A yet further object of my invention is to provide substantially rectangularly shaped hull sections which decrease in height rearwardly, and thus provide said hull with step-formed off-sets rearwardly, preferably from midships to the stern of the ship, giving th bottom of said individual ofi-sets a straight horizontal surface.
Through this construction it is possible to save cost in the building of ships, as each section, that is plates with the attached webframes may be prefabricated, so as to be readily assembled into a complete hull when these sections are welded together, whereby a uniform contraction during welding is attained, thus eliminating locked up stresses.
By this construction, as set forth, it has been estimated that a considerable cost of labor will be saved while an increased speed of the ship is attained.
With the above and other objects in view, this invention consists of the novel features of construction, combination and arrangement of parts, hereinafter fully described, claimed and illustrated in the accompanying drawings forming part of this application, and in which similar characters of reference indicate corresponding parts in all views, and in which:
Figure 1 is a side elevational view of a ship, illustrating my invention.
Figure 2 is a horizontal, longitudinal view partly in section, taken on the line 22 in Figure 1.
Figure 3 is a fragmentary vertical, longitudinal section, taken on the line 3-3 in Figur 2, showing my invention in detail.
Figure 4 is a fragmentary vertical, longitudinal section, taken on the line ll--ll in Figure 3.
Figure 5 is a transverse vertical section, taken on the line '5-5 in Figure 1.
20mins. (01.114519) 1 1 1 9.194 serial Figure 6 is an enlarged detail sectional view, showing the joining of two sections with a webframe.
Figure 7 is a detail sectional view of Figure 6, looking in the direction of the arrow.
Referring more particularly to the drawing, the numeral l0 indicates a ship hull having a reduced underwater portion ll extending approximately from midships to the stem.
The said underwater portion comprises a plurality of sections l2 joined together by means of webframes l3.
Shell plates [4 are welded transversely to the said frames l3, as indicated at [5 and I6.
While the front of the hull is formed with a substantially horizontal bottom, the rear of said hull from about midships is formed with steplike off-sets; the latter decreasing in height towards the stem.
The said hull sections with webframes, which may bepre-fabrlcated, are connected by members l8, the latter having a length equal to distance between two webframes.
While the members [8 of the forward portion of the hull are flush with the webframes, the members I8 at the rear portion of the hull are at the bottom arranged in such a manner as to form step-like off-sets [1.
Thus in welding said members I8 together at the rear bottom portion, each member is in rearward succession welded to the webframe in front thereof .(that is, in direction of the stem); said members l8 forming right angles with the webframes.
While'the shell plates on the sides of the hull and bottom from midships to the stem of the hull are flush and forming seams IS, the shell plates at the rearward portion of the hull from midships, are forming step-like off-sets conforming to the position of the members [8, and are welded to the webframes as at 20 and 2|.
Reenforced plates 22 and '23 ar arranged between the members l8 and webframes 13.
The keel 24, while slanting rearwardly, is secured at the bottom of the webframes and rearward ends of the members l8.
Substantially triangular plates 25, conforming to the spaces formed between the bottom shell plates, the step-lik off-sets and the keel, are welded to the shell plates M as at 26, and the keel 24, as shown at 21.
It is obvious that changes may be made in the form, construction and arrangement of the several parts, as shown, within the scope of the appended claims, without departing from the spirit of the invention, and I do not, therefore, Wish to limit myself to the exact construction shown and described herein.
What I claim as new, and desire to secure by Letters Patent of the United States, is:
1. A ship hull as described, including a plurality of Webframes successively aligned and equally distanced and extending transversely across the hull, members welded to said webframes at right angles to the latter, said webframes off-set successively longitudinally of the hull from about amidships to the stern thereby forming step-like ofi-sets from about midship's to the stern, and shell plates welded tosaid web- I frames across the hull to form sections, a. keel underneath said hull and slanting upwardly toward the stern from approximately midships of the hull, said slanting portion of th keel being secured to one end only of each of the hull sections.
2. In an invention, as claimed in claim 1, and
wherein the shell plates, the step-like off-sets and the keel form triangular spaces, and plates conforming in shape to said spaces being welded into the latter.
GUSTAV MEIER.
