1 Claim.

This invention relates to methods of raising a sunken boat.

An object of this invention is to provide a highly improved method of raising a sunken boat such as the Normandie, which may lie on its side on the bed or bottom of the water.

A further object of this invention is to provide a highly improved method of the character described which shall be comparatively inexpensive to carry out and yet practical and eflicient to a high degree in use.

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, combinations of elements, and arrangement of parts which will be exemplified in the construction hereinafter described, and of which the scope of application will be indicated in the following claim.

In the accompanying drawing, in which is shown one of the various possible illustrative embodiments of this invention.

Fig. 1 is a prospective view of a boat lying on its side in the water with a casing built around the boat;

Fig. 2 is an elevational, vertical, cross-sectional view through the structure shown in Fig. 1;

Fig. 3 is a view similar to Fig. 2, but illustrating a further step in the method;

Fig. 4 is a view similar to Fig. 3, but illustrating a further step in the method;

Fig. 5 is a view similar to Fig. 4, but illustrating still another step in the process of raising the boat; and

Fig. 6 is a view similar to Fig. 5, but showing still a further step in the improved process.

Referring now in detail to the drawing, 10 designates a boat lying on its side on the bottom I I somewhat similarly to the way the Normandie is submerged. In accordance with my invention, the casing I2 is built all around the boat Hi, the casing having side walls l3 and end walls It and the lower ends of the casing being well embedded in the bottom II to permit the water within the casing l2 to be pumped out. The water in the casing is then pumped out so that the boat lies on its side within the casing. All the water is also pumped out of the boat so that it will not be top heavy. It will be noted that the side walls l3 of the casing are so placed as to be substantially parallel to the sides of the boat, or in other words,

as the side walls extend longitudinally of the boat.

The bottom II is then excavated as at 20 on the side only which is beneath the boat bottom 2!. Thus the excavation 263 extends longitudinally of the casing l2 adjacent one side wall I3 thereof. The excavation exposes the side of the boat on which it is lying, preferably one wall 22 of the excavation 20 is inclined downwardly and toward the side wall adjacent the excavation. Care should be taken to excavate only so much as to leave the boat substantially in the position it is lying while the excavation is being made. After the excavation 26 is finished the boat It) may be pulled, pushed or otherwise moved to cause the bottom 2i thereof to be swung down into the excavation 2E). The boat thus moving from horizontal position to tilted position and then to vertical position as shown in Fig. 5 of the drawing. Water may then be pumped into the excavation 20 and into the casing l2 to float the boat. The casing l2 may then be removed.

It will thus be seen that there is provided a device in which the several objects of this invention are achieved, and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiments above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawing is to be interpreted as illustrative and not in a limiting sense.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

The method of raising a submerged boat lying on its side at the bottom of a body of water comprising building a concrete casing around the boat with the side Walls of the casing extending longitudinally of the boat and the lower ends of the walls of the casing embedded in the bottom of said body of water, then pumping the water out of the casing, then excavating within the casing longitudinally thereof and below the boat bottom While making one side of the excavation inclined downwardly toward the side wall of the casing which is adjacent the excavation, then moving the boat to bring its bottom into the excavation, then pumping water into the excavation and casing and floating the boat, and finally removing the casing.

EDWARD J. KYNE.
