UNITED STATES PATENT OFFICE.
GEORGE C. STEVENS, F SEATTLE, WASHINGTON.
" AEEOPLENE ATTACHMENT.
Be it known that I. GEORGE C. STEVENS, a citizen of the United States,and residing at Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Aeroplane Attach! ments, of which the following is a' specication. 'Y
`The invention relates to an improvement in aeroplane attachments, particularly seaplanes capable of alighting onand arising' from. thesurface of the water.
`Sea planes of 'this type are, as is well known, provided with two or more pontoons acting as floating supports for the sea plane. It is the object of the present invention to provide these pontoons, or one'of them, with charge of the water means for controlling an opening 'into the interior of said' pontoon, whereby the pontoon may be permitted to ll with water when the sea plane is supported on the sur' face, and the aeroplane may carry said water filled pontoons over a remote locality and discharge the water from the pontoon over a desired area. The invention is particularly useful to members lo'f the forestry guard, in which service aeroplanes and the like have.been heretofore used to enable the guard to supervise a large territory, as with an available body of water, the guard has at command, a means whereby he may transport a considerable quantity of water to a small or starting re,'and so direct the disas to aid in extinguishinof the fire.
n the drawings Figure l is a side elevation of a sea plane of 'one of the p'ontoons vpartly in section to illustrate the valve-mounting Fig. 2 iS an enlarged plan showing the of the present invention,
of the sea plane 2, and of usual hollow conp n VSpecification of Letters Patent. Patented Now, 15, 1921, rApplication led October 13, 1920. Serial No. 416,608. l'
opening, andsaid valve is adapted to be.
operated by a rod5, which extends through an elongated opening 6 in the top of the pontoon and is pivotally. supported ad- )jacent said pontoon and top between ears Y as more particularly shown in Fig.12.
The rod 5 extends to a-position convenient to the aviator, so that hefmay readily control the opening 3 at will; l In use having) discovered a fire, the. aviator -2- ma-y fly to a ody .of waterand landing upon the Same, permltthe pontoon to ll or partially fill by obvious control ofthe Valve' 3. Then with the water filled pontoon, the
sea plane will be caused to rest on the surface' and fly at an appropriate altitude over the area on fire, when the valve 3 is operated to permit the discharge of the Water from the pontoon onto the burning surface.
Obviously a. number of such sea planes could by the volume of water dischar ed check or even put out a considerable nre,
yand to this'ex'tent the invention is a,valuable Vpivoted in the top portion and having an Y end portion extending into the pontoonadjacent the bottom opening, the other end portion extending to a pointadjacent the operators seat, a valve member pivotedvto the end of said lever within the pontoon and adapted to close the opening in thebottom thereof.4 y
