UNITED STATES PATENT OFFICE.

HENRY V. CORBETT, OF BUFFALO, NEW YORK.

MODE OF RAISING SUNKEN VESSELS.

Specification of Letters Patent No.

To all whom t may concern.'

Be it known that I, HENRY V. CORBETT, of Buffalo, in the county of Erie and State of New York, have invented a new and Improved Mode of Raising Sunken Vessels; and I do hereby declare that the following is a full and eXact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, l making a part of this specification, in whichp Figure l, is a longitudinal elevation showing the lines buoy and weight or weights in their descent to the sunken vessel.

A is a vessel placed over the sunken vessel B B, guy lines to guide the buoy. C, is the hawser by which the weight or weights, D, with buoy E, attached islet down to the` sunken vessel. 4

F, is the windlass.

G, is sunken vessel with buoys attached thereto.

No. 2 isa transverse section of vessel buoy and weight or weights showing how the buoy is attached to the vessel by the hook or hooks and how the weight or weights is detached by raising the weight or weights.

The nature of my invention consists in raising sunken vessels with vbuoys carried down to the sunken vessel by weight or weights attached to the buoy, which weights are readily detached and drawn to the surface when required.

To enable othersv skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

I construct my buoys of wood oriron in any of the known forms of casks and of any desirable size, having suiicient strength to resist the pressure of water at the depth 12,436, dated February 27, 1855.

in which they are to be used. Iattach a hook or hooks at or near the bottom of the buoy of suiicient strength to hold the buoy tothe vessel, and on the opposite side I attach another hook to which I fasten the weight or weights by a hole on one side near the top o f the weight. To the top of which a hawser is attached, thereby allowing the weight or weights to sink. It must carry the buoy down with it guided by the guy lines which are attached to the arms of the weight or weights and checked in its descent by the hawser until it reaches the bottom when by gently raising the weight or weights, the buoy will fasten itself to the guards or anything else I wish to fasten to.

The weight or weights can then be drawn up at pleasure.

I do not claim the Inode of raising sunken vessels by the use of casks filled with water, which is to be pumped out yafter the casks are attached to the vessel, nor do I claim the inode of so doing by means of expansive buoys, `which obtain their buoyant power by iniation after they are sunk and attached to the vessel. But

What I do claim as my invention and desire to secure by Letters Patent is*- The mode of raising sunken vessels by means of casks or buoys previously filled with air, and sunk by a weightwhich is readily detached, and raised to the surface after the buoy is secured to the vessel substantially as herein described and set forth. `HENRY V. CORBETT.
