Ludluiii's JVew Patent Life Boat. 



Matthias Liidlnm, Fair Haven, Vermont; Thos. Carter, agent, 

 205 Eowery New- York. 



It embraces two floats, with air-tight 

 compartments in each, which does 

 away witli the possibility of tlie entire 

 float being destroyed ; also prevents 

 swamping or sinking ; also, two or 

 more self-adjusting valves, and a con- 

 tinuous air-chamber, made in com- 

 partments, so constructed as to be 

 used for lockers and reservoirs. 



The floats supercede the necessity 

 c»f any additional frame-work or fix- 

 tures to secure it in its place. It may 

 go overboard upon its end or side and 

 will not swamp, but immediately right 

 and Iree itself of water. There can 

 be attachments made for covering, by 

 using rack, jiinions and awning, per- 

 fectly portable, and ready for imme- 

 di;ite use. 



The boat can be propelled by oars, 

 sails, or paddle-wheel between the 

 floats. It can be made of any mate- 

 rial of which life-boats are usually 

 made, and of any dimensions. 



The self-adjusting valve that is spoken of is intended to dis- 

 charge the water through the bottom of the boat. Also, to the 

 fact that the apartments of the floats serve a double purpose. 



First. In case of accident, water cannot enter and fill but a 

 small space at the time. 



Secondly. The apartments serve to render the floats unyield- 

 ing to outer pressure. 



The attachment of the floats prevents the boat from capsizing 

 by persons getting on one side; but merely sinking the floats a 

 little deeper in the water on which ever side they may g{>t in.
