FLYING-I-MAVCI-IINE.

Application filed May 15, 1917. Serial No. 168,641.

To all whom it may concern:

Be it known that 1, MICHAEL F. MORRIS-f paddle extending the length of the unit, the paddles of the individual wheels of the unit being arranged to be adjusted for varying their lifting and propelling-action. I

A further object of myki vention is to provide an effective means'ror optionally varying the feathering movements of the paddles and holding them in any givenadjustment. Y

Further objects of the invention andats advantages will appear as the descrlption proceeds.

Reference is to be had to the accompany ing drawings forming a part of this specification in whlch simllar referencecharacters indicate corresponding parts in all the views,

it being understood that the drawings are merely illustrative of one example of the invention. 5

Fig. 2is a front view thereof;

F ig. 3 is a longitudinal vertical sect1on taken through the. body of the machine and illustrating the means for adjusting the feathering means;

Fig. 4 is an enlarged transverse vertical section of one of the paddle wheel units;

Fig. 5'is a vertical section on the line 55, Fig. 4';

Fig. 6 is an enlarged detail view in cross section, showing the manner of feathering thepaddles of each wheel;

Fig. 7 is a developed view showing a portion of the cam for giving the feathering movement to the paddles, the spokes of the paddle wheel being indicated in dotted lines.

In carrying out my inventionin accordance with theillustrat'ed example, a suit- Specification of Letters Patent. I

.any approved motor at A, Fig. 3.

bearings or ball bearings are provided at 30 Patented liamzane e.

able body 10 is provided, and arranged at the sides thereof are paddle wheel units designated generally by the numeral 11. The

machine may be equipped with any desired arrangement of horizontal rudders 12, a vertical rudder 13, and ground wheels 14.

The units 11- extend laterally and they are braced by a system of guy wires, there being front and rear guys 15 .and 16 horizontally disposed, as well as intermediate horizontal crossmg guys 17 between adjacent pairs of units. -Sa1d guy wires brace the machine horizontally; to brace it vertically, upper and lower transverse wires 18, 19 are employed.- Transverse shafts 23 are .provided on which the paddle wheels 24 of each unit are mounted to turn, said shaft being relatively. fixed except as it may be turned for feathering the paddles as will appear. Adjacent to the body 10 the shafts have bearings in brackets 20 or the like,'while on the outer end of each shaft is a fitting 21 which takes the outer ends of the various guy wires 15, 19, the said fittings being essentially of four-armed form in the illustrated example,

said arms receiving the respective guy wires. Each fitting 21 has a thrust bearing 22 wherebythe ends of the shafts'23 will take the thrust or tension of the guywires, whichare firmly tightened up, the arrangement thus relieving thepaddle wheels of any end thrust due to the tautenedfguys.

Each paddle wheel24 is composed of a hub 25 and spokes 26, the outer ends26 of which are of reduced thickness and carry the paddles 27 which are strengthened by brace wires 27, or the. like, arranged diamond-shape on a face of the blade toHprevent the same from buckling. The ends of each blade 27 are flanged at right angles at 27*, the flanges receiving the reduced portions 26 of the spokesand also serving to strengthen the paddle. The hubs 25 of'the.

respective wheels'20' are halved, the halves being flanged as at 25 the flanges being united by bolts 25 or the like, see Fig. 6, whereby the several wheels are connected and the inner hub 25 is integral with .a sleeve or hollow shaft 28 adapted to revolve about the shafts-23. The shaft 28 is driven in any suit able manner, there being shown a.

sprocket wheel 29 driven by belts-29 from. I

Roller adjacent to the. ends of the shaft 23.

In order to turn the'spokes 26 through the required angle for feathering, cam collars 31- are keyed on the shaft 23 and the hubs 25 are hollow to house said collars. Each collar 31 has a peripheral cam groove 33 receiving the enlargement or head 32 on the head of a spoke 20 as shown in Figs. at, 6 and 7. [n the developed view, Fig. 7, it will be seen that the cam groove is defined at one side by a wall 3st and that the walls vary. In prac tice, the cam groove is so formed that the paddles for 120 will be so disposed as to present broad sides on the downward movement, the several paddles in this position, as seen at the bottom of Fig. l, constituting in effect a single paddle extending the length of the unit. The paddles are of a width to overlap when thus disposed broadside and the action of the cam grooves 33 in alternate collars 31 are such as to turn alternate blades to the right and left for feathering in the upward movement and in fact for about 240 of travel. The heads 32 on the spokes are rounded for approximately half the periphery and the remaining peripheral surface is in the form of straight surfaces 35 at right angles to each other, or approximately 50.

To vary the points about the shaft 23 at which the angular position of the blades will be varied, the said shaft 23 is adapted to be turned through a sufficient angle for the purpose. In Fig. 3 a means is illustrated for turning the shaft 23, said means comprising a lever 36 fulcrumed as at 39 on any stand 10 or the like on the floor of the body 10-, and saidlever has a' cross arm 38 thereon which is connected by wires 40 or the like with a. cross arm ll on one shaft 23. To

operate the second shaft 23, by the turning of the one, wires 42 connect a second cross arm 43 on the first shaft with a similar cross arm 4:3 on the second shaft The lever 36 is locked in a given position in the usual manner to a quadrant 37.

i6 connect the several "inner rims lat as naesaoe of each wheel 24 to flanges 48 formed on the hubs 25 between the wheels. Guy wires 49 extend from the said flanges 48 to the inner rim let at each side and, in addition, I pro vide guy wires 50 extending from each rim ell laterally on each side to the flanges of alternate wheels sothat a wire from a guy wire 50 instead of going to the next adjacent flange l8 extends to the second flange, distant from the rim all to which said wire is secured. It will be seen that the various guy wires and the girts give rigidity to the paddle wheel unit.

In practice when the machine is in motion and it is desired to cause it to rise, the lever 36 is drawn to the rearward position to feather the paddles on the front side of the wheels at 70 or thereabouts to present the paddles flatwise on the downward motion. The paddles at the rear of the wheel with the upward movement thereof Will be edgewise, thus without resistance. When the machine has attained the desired height, the

lever may be moved forward, thereby trans-' mitting its motion to the shafts 23, to cause the paddles tc feather at 90 or thereabouts, thus giving a greater propelling motion with still uflicient lifting motion to hold the machine afloat. The paddles move on the working stroke through approximately 120 and more when presented edgew-ise through approximately 240.

I wish to state in conclusion that although the illustrated example constitutes a practical embodiment of my invention, I do not limit myself strictly to the mechanical details herein illustrated, since manifestly the same can be considerably varied without departure from the spirit of the invention as defined in the appended claim.

Hav g thus described my invention, I claim as new, and desire to secure by Letters Patent In a flying machine, a transverse normally fixed shaft, a series of individual paddle wheels mounted to turn in unison on said shaft, drive means for said paddle wheels, fixtures on the ends of said shaft, @0- acting feathering means on the paddle wheels and on said shaft, means to turn the shaft relatively to the said fixtures and to the said paddle wheels, and guys exerting end thrust between the said fixtures and the said shaft, independently of the paddle wheels.
