Patented Dec. 3, 1929 JOHN ADAMS, 015 DETROIT, MICHIGAN AIR SUPPLIER Application filed February 25, 1929.

My invention relates to a new and useful improvement in an air supplier adapted especially for use on bodies which are used on the water such as row boats, canoes, ships, etc, and particularly adapted for use on that class of Boating body which is covered by a super-structure.

It is an object of the present invention to provide a device of this kind whereby air may be admitted to the closed super-structure while at the same time entry of water into the super-structure may be prevented.

It is another object of the present invention to provide a device of this class which will be simple of structure, economical of manufacture and highly eflicient in use.

Other objects will appear hereinafter.

The invention consists in the combination and arrangement of parts hereinafter described and claimed.

The invention will be best understood by a reference to the accompanying drawings, which form a part of this specification, and in which,

Fig. 1 is a central vertical sectional view with parts broken away.

Fig. 2 is a sectional view taken on line 2-2 of Fig. 1'.

Fig. 3 is an enlarged fragmentary perspective view illustrating one of the port closures.

The .invention is illustrated as mounting on a body having a super-structure 7 and comprises a hood or drum 8 to which is attached the ring 9 which fits over and is secured to the super-structure 7. Projected through one end 10 of the drum 8 are conical tubes 11 which extend through tunnel shaped braces 12 secured to the outer surface of the side 10. These tubes extend well toward the top 13 ot the drum and project below the top 1% of the superstructure 7. Extended through the top 13 of the drum are tubes 15, which serve to communicate the interior of the drum with the atmosphere. Ports 16 are formed in the side walls of the drum and are closed by port closures 17 which are swingably mounted between lugs 18. It will be noted that the inner ends of the tubes 15 Serial No. 342,410.

project below the upper ends of the tubes or pipes 11.

In use, when the device is mounted as illustrated, air entering the drum 8 through the opening 16 and through the pipes or tubes 15, will be permitted to enter the interior oi": the super-structure '7 through the pipes or tubes 11, at the same time, the ends of the pipes 11 being positioned above the wall 10 and below the inner ends of the pipes 15, will not conduct water, which may be slapped against the drum 8, into the interior of the super-structure 7.

In this way, I have provided a device whereby air may be supplied to the interior of the super-struction '7 without conducting water or permitting leakage of water into the interior of the super-structure 7.

lVhile I have illustrated and described the preferred form of my invention, I do not wish to limit myself to the precise detail of structure shown but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. An air supplier of the class described adapted for use with a super-structure comprising: a drum; a ring secured to and projecting outwardly from one end of said drum and embracing said super-structure, said drum having openings formed in its sides; swingably mounted closures for said openings; a plurality of tubes communicating with the interior of said drum and projecting into said super-structure; and means for communicating said drum adjacent its upper end with the atmosphere.

2. An air supplier of the class described adapted for use with a super-structure comprising: a drum; a ring secured to and projecting outwardly from one end of said drum and embracing said said. super-structure, said drum having openings formed in its sides; swingably mounted closures for said openings; a plurality of tubes communicating with the interior of said drum and projecting into said super-structure; and means for communicating said drum adjacent its upper end with the atmosphere, said means projecting inwardly of said drum beyond the upper ends of said tubes.

3. A device of the class described comprising: a drum; a plurality of tubes projecting 5 inwardly of said drum and terminating adjacent the upper end thereof; a plurality of tubes projected through said drum for communicating the interior thereof with the atmosphere, the inner ends of said atmosphere tubes projecting below the upper end of said first mentioned tubes.

4. A device of the class described comprising: a drum having a plurality of openings a formed in its side; swingably mounted closures -for said openings; a plurality of tubes projected through the lower side of said drum and extending well upwardly to the upper side thereof; a plurality of tubes projected through the upper side of said drum and extending below the upper end of said first mentioned tubes, said second mentioned tubes commuicating the interior of said drum with the atmosphere.

5. A device of the class described comprising: a drum having a plurality of openings formed in its side; swingably mounted closures for said openings; a plurality of tubes projected through the lower side of said drum and extending well upwardly to the upper side thereof; a plurality of tubes projected through the upper side of said drum and extending below the upper end of said first mentioned tubes, said second mentioned tubes communicating the interior of said drum w1th the atmosphere; and a ring secured to and projecting outwardly from one face of said drum.

In testimony whereof I have signed the foregoing specification.

JOHN ADAMS.
