OIL-DISTRIBUTING APPARATUS FOR CALMING WAVES.

SPECIFICATION forming part of Letters Patent No. 710,013, dated September 30, 1902.

Application filed September 28, 1901. Serial No. 76,936. (No model.)

To all whom it may concern:

Be it known that I, NILS SALVESEN, a subject of the King of Sweden and Norway, residing at Grimstad, Norway, have invented certain new and Improved Oil-Distributing Apparatus for Calming Waves, of which the following is a specification.

I have by trials on the sea invented a device by which I am able to work bags or vessels filled with oil for sea-calming purposes from the ship against the wind to any desirable distance from the ship.

I carry out my invention by employing a floating body and provide the said floating body with suitable means'for instance, a loop, or a ring, or a tail-blockthrough which I pass a cord, rope, or the like. When the case arises that it is desirable to break the waves, I throw overboard the floating body, let the vessel drift, all the time paying out the cord or rope, until the vessel has drifted the desirable distance from the floating body. I now stop paying out the cord, and having fastened a bag or vessel filled with oil to the one part of the running cord I am able to work the said oil-filled bag or vessel to any desirable distance between the vessel and the floating bod y. When the bag is empty, I haul it back, at the same time sending out a fresh bag filled with oil attached to the other part of the line. For safetys sake and also for the easy working of the running line I have fastened to the floating body the one end of a hawser, the other end of which is fastened to the vessel. By this means I am able to keep a steady supply of oil on the windward side of the vessel and at such a distance from the vessel that the oil will act in the most efficient manner.

In order to more fully explain my invention, I refer to the appended drawings, on which I have shown a suitable form of my device in which a bag of canvas or other suitable material forms the floating body.

In the drawings, Figure 1 shows the said floating body in elevation; Fig. 2, same in front view, and Fig. 3 is a plan view showing the way of working oil-filled bags or vessels between a ship and the said floating body.

As mentioned above, the floating body is made in the shape of a bag of canvas 0;, which is open in front and provided in the bottom with a small aperture 1). The said aperture is provided in order to reduce the pressure of the wateron the bottom of the bag and also for the purpose that the jet of water produced through the said aperture shall steer the bag and give it a steady motion in the water. The foremost end of the bag is kept expanded by any suitable meansfor instance, a solid ring 0, to which the edge of the bag is fastened in any suitable manner. The bag is at the middle and at the hind end near the bottom provided with rings (1 and e, of slightly less diameter than ring 0 for the purpose of keeping the bag in an expanded state. However, the arrangement of these latter rings 01 and e is not considered to be necessary because the pressure of water will be quite sufficient to keep the bag in an expanded state. The ringc might be provided with eyes 8, in which the end of the hawser from the vessel should be fastened. The bag a is further provided with swimmers f, which by means of a cord g are attached to lugs h and j on the top of the bag a, the object of the swimmers being to keep the bag suitably immersed in the water and also to prevent the turning of the bag at around its longitudinal axis. In order to further prevent any such turning, the bag is provided with a ballast-rod it, supported in lugs Z and m at the under side of the bag, the said rod having a head 'n in the one end and in the other a hole in which to insert a splint 0, whereby the rod is kept in place. The bag a is on its sides provided with lugs 19 and q, fastened to the rings 0 and e for the purpose of attaching the running line 7, with which the oil-bag u is to be worked, between the vessel and the bag a. Of course the line r might as well run in tail-blocks fastened to the bag a.

Supposing the vessel at the point t, Fig. 3, is overtaken by stormy weather or any mishap occurs, the bag a is attached to a hawser and aline is passed through the lugs 19 and q, whereupon the bag is thrown overboard. While the vessel is drifting off, the direction of the wind being indicated by the arrow, the hawser and the line 0 are paid out until the vessel has reached a suitable distance from the bag. The hawser is now fastened to the side of the vessel and an oil-bag is attached to the one part of the running line r and hauled out tothe desired distance from the vessel. Now when the weather has calmed or the accident has been remedied the pressure maintained by the line connected to ring 0 is released, when the bag will collapse, the same being hauled into the ship by pulling in the running line 1', connected to ring 6.

Having now described and ascertained the nature of my invention and in what manner the same is to be carried out, I declare that what I claim as new, and desire to secure by Letters Patent, is-

1. In a device of the character described, a collapsible bag, a series of suitably-spaced annular rings of slightly-varying diameter secured to said bar, one of said rings being secured at the forward end and one at the rear end of said bag, said bag to the rear of said last-named ring having a contracted opening therein, lugs carried by the said rings, means secured to said lugs and extending in alinement with the length of said bag for preventing the bag from turning ox'er on its lon- 1 gitudinal axis, and means connected to said forward ring for connection with the vessel, substantially as described.

2. In a device of the character described, a collapsible bag, a series of rings secured to said bag for retaining the same in an expanded conical shape, one of said rings being secured to the front end and one to the rear end of the bag, said bag having a tapering extension with an opening therein beyond said rear end of the bag, lugs secured to the rings on the under side thereof, a ballast-rod secured in said lugs and extending the length of the bag, swimmers carried by the said lugs, and means for connecting the bag to the vessel, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

NILS SALVESEN. \Vitnesses:
