The pipe 22 is in open communica which the following is a , clear, and tion with the compression cylinder 23. The exact description. . compression chamber 23, as shown best in 65 Among the principal objects which the Fig. 2 of the drawings, extends within the 10 present invention has in view are: to pro chamber of the tank 7 and opens outwardly vide means which may be incorporated in therefrom the structure of small seagoing boats or rafts piston 24 isthrough the side wall thereof.
