Specification of Letters fatent.

Patented June '29, 1920.

Application filed June 4, 1919. Serial No. 301,619.

To all whom it may concern:

Be it known that I, Grusnrrn VrrULLI MONTARULI, a subject of the King of Italy, and residing at 9 Piazzale Flaminia, Rome, Italy, have invented certain new and useful Improvements in the Construction of Ships, of which the following is a specification.

My invention relates to the construction of surface-going ships and consists of an improved form of hull of the type described in my previous Patent Number 1,295,786,

- granted Feb. 25, 1919, in which the waist of the ship has curved transverse frames throughout and the end portions have frames whose cross-section is formed of circular segments above and below and straight lines of gradually increasing length laterally.

According to the present invention the transverse frames of the central portion of the hull are not in the shape of a continuous curve of, for example, circular, elliptical or oval cross section, but the curve is in terrupted at points by straight lines connecting with the curved parts.

The invention is illustrated by way of example in the accompanying drawing, i which- I Figure 1 shows on the left-hand side the midship section of the hull and on the righthand side the curvature of this section,

Fig. 2 shows the hull divided into three parts of different geometrical shape,

Fig. 3 shows in plan and

Figs.v

4 and 5 in projections of vertical sections, the shape of the hull forward and aft.

In Fig. 1, the curved portion A, B, C is a semi-circle which has its center at D and connects at its ends A and C with rectilinear parts A E and C F so as to make up a frame which consists of a circular part A, B, C and of rectilinear parts E A and C F above and below to form half a section of the central part 3 in Fig. 2 of the hull.

The forward end 4 (Fig. 2) is built up from section 6 of midship section onward with the aid of sections 7, 8, 9, 10 and 11 which consist of circular arcs connected b straight lines above and below and of gra of midship section so as to reach gradually along sections 14, 15, 16, 17 and 18 the rectilinear vertical stern section 19, the only difference between the forward and after endportions being that the latter is tapered below so as to leave there a free space for the working of the screws.

The shape of the hull built up in the above described manner allows of its main parts being constructed with interchangeable elements of constant curvature, whereby a standardization of the construction is attained for building ships in series.

As regards the central portion of the ship, this construction is shown in cross section at 1 on the left and diagrammatically at 2 on the right hand side of Fig. 1. In this central part the section of the hull consists substantially of a frame 20 which may have the section of any ordinary bar used in shipbuilding, and of layers of plates to form the outer plating 21.

A double bottom 22 may have any desired shape, and 23 is a hatchway and 24 a section of the deck in communication with the hatchways.

It is to be understood that the rectilinear interruption or interruptions of the curve which forms the cross section of the waist, may be provided at any desired or appropriate point or points, for example, above and below, as described, or laterally, and 1 so on.

a What I claim is:

1. A ship having a plurality of transverse frames, the frames throughout the waist of the ship being in the shape of a plane curve interrupted at points by straight lines, and the end portions having similar frames with straight lines at the sides of gradually increasing length.

2. A ship having a plurality of transverse frames, the frames throughout the waist of the ship being in the shape of a curve interrupted at points by straight lines and the end portions having. cross sections formed of similar curved sections having vertical straight portions of gradually increasing length toward the ends.

3. A ship having a plurality of trans verse frames, the frames throughout the waist of the ship bein in the shape of a curve interrupted at points by straight lines and the end portions have cross sections formed of curved segments with straight name, in the presence of two subsei ibing lines above and below and straight lines of Witnesses, at'Rome this 3rd day of May, gradually increasing length at the sides, the 1919.

frames of the after end being shaped so as GIUSEPPE VITULLI MONTARULI. 5 to provide for the said end being tapered Witnesses:
