UNITED STATES CLAS J. JACOBSSON, OF NEW YORK, N. Y.

REFLOATING APPARATUS FOR STRANDED VESSELS.

Application filed September 18, 1924. Serial No. 738,474.-

To all who-s22 it may concern:

Be it known that I, CLAs J. JACOBSSON, a citizen of the United States of America, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Refloating Apparatus for Stranded Vessels, of which the following is a description.

My invention relates to means which when used in association with a stranded vessel will tend to cause the vessel to move toward deeper water for floating.

The general object of my invention is to provide a device for the indicated purpose involving anchors to be placed seaward from the vessel and means attached to the vessel as well as intermediate floatable means and so arranged that the action of the waves will be utilized in giving a lifting and displacing action to the stranded vessel and tend to cause the same to move to deeper water.

The nature of my invention and its distinguishing features and advantages will clearly appear as the description proceeds;

Reference is to be had to the accompanying drawings forming a part of this speciflcation, it being understood that the drawings are merely illustrative of one example of the invention.

Figure 1 is a side elevation of an apparatus showing the same in use in connection with a stranded vessel;

Figure 2 is a plan view of the apparatus, the vessel being indicated diagrammatically;

Figure 3 is an elevation of the attachment to be applied to the hull of the stranded vessel, the vessel being indicated by dot ted lines in said view;

Figure 4 is an enlarged section on the line 4-4, Figure 3;

Figure 5 is a perspective view of the float ing device disposed on the cables between the anchor and the stranded vessel;

Figure 6 is a transverse vertical section through the floating device as indicated by the line 6-6 of Figure 5.

In carrying out my invention in accordance with the illustrated example, cables 10 are employed having anchors 11 designed to be disposed seaward from the vessel A to be floated. The cables run to any suitable winding apparatus to be employed, such as a suitable windlass or capstan 12, the cables running to said winding means over sheaves 13.

A U-shaped band 14 is provided to be posi tioned beneath the vessel at the stern, assum ing the stern to be disposed toward the deeper water. A floating device designated generally by the numeral 15 is employed and the cables run through suitable guides 16, 17 disposed thereon at each side, said guides being illustrated as in the form of brackets having holes for the passage of the cables, there'being a pair of holes 18 indicated in each bracket 16, 17. The floating device 15 includes a trough-shaped structure having an air cylinder 19 at the forward edge at the top of said trough-like structure. The cables also run from the floating device 15 through guides 20 equipped with sheaves and disposed at each side of the strap or band 14 and the cables run from the guide 20 to the winding device 12.

The band 14 is metal and is readily positioned beneath the vessel A adjacent the stern. Said band 14 is held in place by cable 21 made fast or held against displacement on the deck of the vessel A.

With the described construction the anchors having been carried out into deep water to the desired position to insure the holding of the anchors and with the floating device positioned between the vessel A and the anchors 11 and with the cables running through the guides 16, 17 the open front end of the trough-like structure or floating device 15 being disposed toward the vessel, the cables are wound so that with the anchors resisting a force tending to move the vessel toward the anchors will be exerted on the vessel A. The trough-like structure of the float l5 materially assists the resistance afforded by the anchors. In addition the action of waves on the floating device 15 will cause the same to move vertically causing it to disturb the water and the sand or other bottom beneath and in the region of the floating device 15, the purpose being to displace the bottom and make deeper the water in the region of the vessel. The original position of the floating structure 15 is indicated by dotted lines and as'the cables are wound in, said structure, in addition to of fering a resistance to a forward movement thereof by reason of its trough-like form and open front, exerts through the cables a lifting action on, the near end of the vessel A to contribute to the displacement of said vessel and facilitate its movement toward deeper water.

On each cable is means to limit the movement of the floating structure in the direction of the anchors, there being shown for the purpose in the illustrated example, enlargements 22 on said cables.

I would state in conclusion that while the illustrated example constitutes a practical embodiment of my invention, I do not limit myself strictly to the exact details herein illustrated, since, manifestly, the same can be considerably varied without departure from the spirit of the invention as defined in the appended claims.

Having thus described my invention, I

claim:

1. In an apparatus for re-floating stranded vessels, cables adapted to be connected with a Winding means on a stranded vessel, an element adapted to be disposed beneath the vessel and having guides for said cable, anchors for the cables, and a floating structure on said cables between the anchors and said element for olfering resistance to the movement of the cables when wound in and adapted to be given an up and down movement by Waves to exert a lifting action on the vessel through the cables.

2. In an apparatus for re-floating stranded vessels, cables, means adapted at one end to be connected with winding means on a stranded vessel, anchoring means for said cables, and a floating structure, said structure, strung on said cables, and presenting an open front to offer resistance to a movement of the cables toward the vessel and thereby contribute to the resistance opposing a bodily movement of the cables toward the vessel.

3. I11 an apparatus of the class described, a cable adapted to be connected at one end with winding means on a stranded vessel, anchoring means for said cable, and a bowed element adapted to be disposed beneath the strandedvessel, said element having guides thereon through which the cable passes, together with means additional to the cable for securing said element in position.

4. In an apparatus of the class described, cables adapted to be connected at one end with winding means on a stranded vessel, anchoring means for said cables, and a floating structure, said structure presenting a hollow body open at the front, and an airtight cylinder on said body at the top.

CLAS J. JACOBSSON.
