Abstract

The present invention is a view port suitable for installation under the water line of a vessel wherein the view port comprises a flange made from a corrosion resistant material and a body made from a heat resistant material. An alternative embodiment of the invention is an underwater light in which a high intensity light and ballast is completely installed into the above mentioned view port.

Claims

exact text as granted — not AI-modified
1 . A thru-hull housing comprising: 
 an annular external flange having an annular opening,    a cylindrical, hollow main body removably attached to the external flange;    a lens sized to fit the annular opening of the external flange,    a means for securing the lens to the external flange,    a means for providing a watertight seal on both sides of said lens; and    a means for securing the housing to a vessel.    
   
   
       2 . The thru-hull assembly of  claim 1  wherein the means for securing the housing is selected from bonding, welding or mechanical fastening.  
   
   
       3 . The thru-hull assembly of  claim 2  wherein the mechanical fastening means is a locking ring.  
   
   
       4 . The thru-hull assembly of  claim 3  wherein the locking ring is used with a compression ring.  
   
   
       5 . The thru-hull assembly of  claim 1  wherein the means for securing the lens to the external flange is selected from bonding or mechanical fastening.  
   
   
       6 . The thru-hull assembly of  claim 5  wherein the mechanical means for securing the lens to the external flange is a glass retaining ring.  
   
   
       7 . The thru-hull assembly of  claim 1  where the means for providing a water tight seal is selected from sealants, o-rings, gaskets or mechanical seals.  
   
   
       8 . The thru-hull assembly of  claim 7  where the means for providing a water tight seal is a gasket.  
   
   
       9 . The thru-hull assembly of  claim 1  further comprising a cap threaded onto the distal end.  
   
   
       10 . The thru-hull assembly of  claim 9  further comprising a source of light.  
   
   
       11 . The thru-hull assembly of  claim 10  wherein the light is selected from halogen and metal halide.  
   
   
       12 . The thru-hull assembly of  claim 9  further comprising a camera.  
   
   
       13 . The thru-hull assembly of  claim 1  wherein the flange and the housing are comprised of two different metals.  
   
   
       14 . The thru-hull assembly of  claim 13  wherein the flange is selected of a highly corrosion resistant material.  
   
   
       15 . The thru-hull assembly of  claim 13  wherein the housing is comprised of a heat dissipating metal.  
   
   
       16 . A thru-hull light comprising: 
 an annular external flange having an annular opening,    a cylindrical, hollow main body removably attached to the external flange;    a light housing removably attached to the main body,    a lens sized to fit the annular opening of the external flange,    a means for securing the lens to the external flange,    a means for providing a watertight seal on both sides of said lens disc; and    a means for securing the housing to a vessel.    
   
   
       17 . The thru-hull light of  claim 16  wherein the means for securing the housing is selected from bonding, welding or mechanical fastening.  
   
   
       18 . The thru-hull light of  claim 17  wherein the mechanical fastening means is a locking ring.  
   
   
       19 . The thru-hull light of  claim 18  wherein the locking ring is used with a compression ring.  
   
   
       20 . The thru-hull light of  claim 16  wherein the means for securing the lens to the external flange is selected from bonding or mechanical fastening.  
   
   
       21 . The thru-hull light of  claim 20  wherein the mechanical means for securing the lens to the external flange is a glass retaining ring.  
   
   
       22 . The thru-hull light of  claim 16  where the means for providing a water tight seal is selected from sealants, o-rings, gaskets or mechanical seals.  
   
   
       23 . The thru-hull light of  claim 22  where the means for providing a water tight seal is a gasket.  
   
   
       24 . The thru-hull light of  claim 16  wherein the lamp is selected from halogen or metal halide.  
   
   
       25 . The thru-hull light of  claim 16  further comprising a camera.  
   
   
       26 . The thru-hull light of  claim 16  wherein the flange and the housing are comprised of two different metals.  
   
   
       27 . The thru-hull light of  claim 26  wherein the flange is selected of a highly corrosion resistant material.  
   
   
       28 . The thru-hull light of  claim 26  wherein the flange is selected from stainless steel, bronze or titanium.  
   
   
       29 . The thru-hull light of  claim 26  wherein the housing is comprised of a heat dissipating metal.  
   
   
       30 . The thru-hull light of  claim 26  wherein the housing is comprised of aluminum, titanium or brass.
