To all whom it may concern;

Be it known that 1, Mix STUPAR, 2. citizen of the United States of i irnerice, residing at Buffalo, in the county 01, Erie and State of New York, have invented certain new and useful improvements in R udder for Hydrostructure including afloat below the air di rectionztl rudder having water planes and a. water rudder to protect and assist the air rudder when the machine is on the water.

A still further object is the provision of a tail structure including aneir directional rudder in connection with means to protect the same in the water and additional means to protect the last named means when on land.

These and other objects, as well as the re sultlng advantages of my invention will he better understood by reference to the so companying dmwings, torming a port of this specification, and where 1-- Figure 1 is a side eievation oi n proved hydroaerophine,

Fig. 2 is an enizirged side view oi the iower portion of the toil structure,

Fig. 3 is an enlarged sectional side view of the rudder brace,

Figi is a side view of the rear portion of the fuselage and the tail post,

Fig. 5 is u rear view thereof, and

Fig. 6 is an enlarged rear elevation of the entire toil structure.

Referring now to these figures end particularly to Fig. l, I have shown it hydrouerophine consisting of u tusciuge 10, wings l1. and main pontoons 12, and oi which the tail structure includes a stedulirer, seen at 1.2% which supports the elevators l nection at its ccutlzai res-a pm 1* s with the upwardly projcc which is provided with 2: depending tube 1 Lo ohl y connected by a cross pin wit application filed i iccemoer Divided and this extension 15 of o te" "ost fitting 16 secured to the rear end ot l uselage l0.

From Figs. -l and it wil also that the tail post fittinr; 16 has t side portions epertured ears 1'? in which then lower ends or the stabilizer hrs-aces 18 are detach-ably secured by locking pins of suitable construction. These are hingedly connected to the lower surface, of the stehilizer adjacent to its outer rear ends, as as seen in Fig. 6.

The vertical air directional rudder l9 detachahiy hinged to the tail post fitting by means of the rudder'post' 20,'the latte.

extending downwardly through tail no 22 which i provide at the lower end 01": Le air directlonal rudder 19 for pnrioses o greater stability when afloat. This tuii host 22- preterahiy has overticei fin 23 at its 7 forming a water rudder, and has horizo :hns its opposite si e forming water planes to give greater stecrnge we}:

the tube 21 depends throui as above stated, and. is vertically socket fitting 26 upon the upper sum the rear end on. the rudder hre -e 27 in the natiu'e of a tail skid, whose forward upper end is hingediy connected at 28 to the lower surface of the fuselage 10 and whose rear end extendsheneuth and protects the tail tioot 22 and its fins 23 and when on hind.

he rear lower end oi the rudder brace 97 is yieldingly supported. in spaced reletion to the float 2 by mean coiled, as seen in lid. 3, even and conipres hctnpen the he. socket fitting: of the skid It will thus be obvious that he '5 22 will citcctivcly si'ipgioiw tho mil in the water so as to protect the tionul rudder. end at the sumo 1' the seine in its passage threw pnrticului'ly hy virtue of the and that its.,.wutcr rudder assist stccrngro way, v

2. Ina flying machine, an airdire'ctional rudder, a float adjacent to the lower end of said rudder,'a .watei 'rudder carried by said '4. In a flying machine, an air directional rudder, a float adjacent to the lower end of said air rudder, a float support and a protecting skid below said float, said skid having a vertically yielding connection with the float support, as described.

5. In a flying-machine, an air rudder having a rudder post provided with an extension depending below the rudder. a float at the lower end of the rudder through which said. extension passes, and a protecting skid below the float having a yielding connection with said rudder post extension.

In testimony whereof I afiix my signature.
