Application filed 311118.24,

This invention relates to improvements in boat construction or other floating apparates. More especially it relates to the sub stitution and use of materials which are lighter in weight, incombustible, and less expensive than the materials now usually employed inthe'construction of the hull of boats. Heretotore, it has been a common practice to construct the hull of longitudi- 10 nal strips of wood or metal of various kinds which are required to be carefully fitted'together and bent'to conformto the shape of the ribs, bow and st-ern. Also, concrete hulls have been constructed with the use of forms or moulds. I

The present invention broadly considered, resides in the use of a material in combination with structural shapes such as channels, I beams, angle or T shaped ribs which extend transversely from one side to the other of the hull and to which are secured the strips of cork b0ard, gypsum blocks, Lith material, which is a trade name of a product that is composed of grasses, metal lath, or other materials and to which material a plastic substance will adhere. These materials may be formed and treated in the same manner as a boat "hull which is constructed of wood or metal. Located on the outer surface of the cork board or other material is a coat or layer of damp or waterproofing material which'may consist of asphalt or other waterproofing compounds. Outside of the layer or coat of the waterproofing material is a layer of cement, plaster, or other plastic materials, which may be applied in any suitable way as by hand, the floating or spreading process, or with a spraying apparatus without the use of forms or moulds and which may or may not be reinforced with a metal lath. The inner surface of the cork board or other material has applied thereto a coat or layer of water-proofing material, and, on this material is a layer of plastic material which may, or may not be reinforced with a metal lath.

Referring to the drawings:

Fig. 1 is understood to be a transverse sectional view on a plane which is parallel with one of the transverse ribs showing the keel in section to which the ribs are secured and the cross connecting bar atthe top of the ribs when necessary or desired, and the layers of cement plaster in section.

F ig. 2 is a sectional view substantially on 1926. Serial no. 118,208.

a plane indicated by the line 22 of Fig. 1

means of rivets, bolts, or. other means 4.

These ribs are arranged about twelve inches from center to center lengthwise of the boat.

5 designates strips of cork board or other materials WlllCll extend lengthwise and 7 cross wise of the boat and are secured to the .or damp proofing material which are applied to the opposite surfaces of the strips of cork board 5. This layer may consist of asphalt or other waterproofing compound. 11 designates a layer of cement plaster, or other plastic material, that is applied to the outer surface of the waterproofing material 10 by any suitable way as by hand, floating or spreading process, or forced thereon by means ofa pressure pump. 12 is a layer located on the inner side of the hull which may consist of a layer of cement plaster, or other plastic material which is applied directly to the layer of waterproofing material 9. It is understood that the plastic ma. terials may be tinted any desired color and the surface rubbed down and painted or that hardening and waterproofing compounds may be added to the same. The cork board or blocks of gypsum material may be sawed in the same manner as wood and will firmly retain a nail. 13 designates a transversely located connecting bar which comprises a metal or wooden member that. is attached to the upper ends of the rib 2 when necessary or desired. 15 is a layer of cement plaster or wood. The webs of the ribs 2 are, as shown, notched at 2 for spanning the keel 1. 1

It is to be understood that I may, if desired, make use of metal lath in the con struction ofthe hull, which lath is secured Y to the metal lath by hand, or spraying proc- I ess, and, without the use of forms or moulds of any kind.

It is to be understood that the cork board may be reinforcedwith metal fabric in place of metal lath.

What I claim is:

1. A boat construction comprising trans on the waterproofing material, and means for securing the corkboard to the T-shaped rib member of the boat.

2. A boat construction comprising strips of cork like material, the inner surface of which material is coated with a layer of water proofing material, a layer of plastic;

material in. contact with, thewater proofing material, keel, and T-shaped ribs to which the keel is secured, and means for securing the cork-like materials to the ribs.

I 3. A boat construction comprising in com bination, a keel, transverselylocated ribs secured to the keel, afilling material secured to the ribs, an inner and outer layer of plastic material secured to the filling material,

'waterproofing material located between the plasticmaterial and the filling material.

l. A boa-t construction comprising a hull composed of strips of cork material, T- shaped:ribs-betweenwhich the strips of cork material are supported, means for securing the. said strips to the T shaped ribs, a T shaped keel, the vertical webs of the/ribs being notched at their inner ends for spanning the vertical web of thekeel, means for securing the llOTlZOIltELl; webs of the ribs to the horizontal web of the keel, a waterproofing asphalt material on the inner and outer surfaces of the cork material, and a cement substance on the inner and outer surfaces of the water-proofing asphalt ma terial. v
