A iiorney Patented May 6, 1930 UNITED i STATES HOMER c. DOUGLAS, onL'IBERAn A'nsAs vEssnL 1" Application filed March 1 5, 1929. Serial No 347,297.

The present invention relates to improvements 1n seagolng vessels, and an lmportant ob ect of the invention is to increase the speed by reducing resistance, to increase the efficien-- cy in handling by permitting the vessel to turn within its own length and to be slid water line pontoons, a cabin pontoon, and power pontoons.

Another very important object of the in vention resides in the provision of water type tubular members for interconnecting the pontoon. Y

A still further very import-ant object of the invention resides in the provision of a vessel of this nature which is strong and durable, thoroughly efficient and reliable for the purpose intended.

With the above and numerous other objects in view as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawing:

Figure 1 is a side elevation of a'vessel embodying the features of my invention; Figure 2 is a top plan view thereof; Figure 3 is a ragmentary longitudinal section, and

Figure at is a vertical transvers section. Referring to the drawing in de ail it will particularly in I These pontoons maybedivided PATENT: oFFIC I be seen that the numeral 5 denotes cabin P toon which is pointed atit-s ends. and has a keel 6 on its bottom. Lifeboats 7 aremounted on this pontoon. At the frontend of the pontoon are windows 8. Numerals 9 denote a palr of waterline pontoons having pointed ends. i.

. 'ljhese pontoons 9'are disposed below and one to each side ofthe pontoon 5. Arcuate tubeslO connect the pontoon 5 with the pontoons 9. :Numerals 11 denote a pair of power pontoons one below each pontoon 9 and connected therewith'by vertical tubes 12. Ladders or Stairways are provided in the pontoons 5, 9 and 11 and in the passagewaytubes. 7

access to any of the pontoons. 1

Braces 16 are provided between the arcuate tubeslO and arcuate bracesv 17 are provided between the pontoons 9 passing over the top of the pontoon 5. Propellers 18are provided at the pointed ends ofthe pontoons 11 and are'operated by suitable engines 19 mounted in the pontoons 11.

10 and 12 so that the crew may, easily have so as to F provide storage chambers 20 for gasoline 7 andtthe like. Rudders 21 are providedon therear side of the tubes 12 being hingedly mounted as is indicated at 22 and operable by, suitable means 23 preferably from the front end of the passenger pontoon-5. By the proper manipulation of these rudders in connection with the propeller it will be seen that the vesselmay be moved sideways,--may be turned in its own length and maybe ma- 2;:

neuvered forwardly or rearwardly at great speed because of the limited orminimum re-: sistance afforded. Furthermore it will be seen that the structure may be used to advantage for salvage work and great" Weight may be lifted. Just way of'eziample Ihave indicated a sub marine at 30 being hoisted by suitable cable means31. This structure may be used as an aeroplane carrier and for other suitable purposes. v s

Hatch covers 34: are preferably provided on the pontoons 9 and 11. It is thought that the construction, utility and advantages of this invention will now be quite apparent to those skilled in this art without a'more detailed description thereof.

In the present embodiment of the invention I have disclosed a structure particularly adapted for carrying passengersand freight. Bridges 36 are mounted forwardly and=rearwardl-y-ofthe structure. Obviously changes in the details of construction and in combination and arrangement ofparts may be resorted for adapting thevess'el'to difif'efitde bers connecting the water line pontoons with the power pontoons, all of said pontoons hav 7 sired purposes without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

Having thus described my invention, what Iclainrasnewis: i
