Bearings are secured to thebars. Sand ,9, in which bearings shaftsll l arejournaled, the

V shafts supporting the cylinders 12:that .are

arranged on opposite sides" of" the machine;v

7 On the inner ends of the shaftsl l are pinions 13', which pin'i'ons are in mesh-with the Wdrins fuselage of'the machine is indicated generally the machinefintofr'ont and- *rea'r'sections;

14-,sfdrrned at theouter ends of the transverse shafts 15-that arerhounted in the bearings 16 alsdsecured to the'vertica'1bars'9s V Mounted on the shafts 15 are p'i-nions thatinesh Wit-li pinions18 secured to the upper ends of the vertical shafts 19; there being provided pinions 20 on the lower ends of the 1 v gm that duetothis the shafts being provided with pins 28 to permit of rotary movement of'the shafts 27,

but at the same time restrict lateral movement of the shafts. Extending through each shaft 27, is an arm 29, the arms 29 having their ends secured to the cabl'es30 that extend over the pulleys 31 mounted at the outer ends of the. rames 23, the opposite ends of the cables Y moving over the pulleys 32 mounted at the opposite ends of the frames 23, theends of the cables bein 'connected to the o eratin disks 33 that'are securedto the inner ends of theshafts "34'- which are shown as iextending throughthe inner ends of the cylinders .12.

The shafts 34 operate through openings in the end members 26 and are supplied with coiled springs 35 that normally act to urge the disks 33 into close engagement with the brake shoes 36 that are secured to the brakes 37 mounted on the end members 26, to the endthatthe disks 33 are normally held against rotary movement. Mounted on each.

shaft 34 is an arm 38 which .is secured toits shaft to rotate therewith; At the outer end in thepath of travel .of the arms 38. With disks are rotated the action of .the'arnis 38 which contact withthe heads 42 and 43 respectively. that aresupported bythe :frame of the machine, andllie each rotation of the cylinders, the arms contacting withv the heads 42 cause the disks to rotate to shift the shafts-27 to'various angles to cause the blades or planes 44 mounted'at the outer ends of the shafts 27'to move to various positions. i

The movements of the arms 38. are timed. so

' that when the blades or planes 44 are on' the outside of the machine, the blades willbe in horizontalpositions, or slightly tilted from their-horizontal: positions, to exert an upward thrust on the machine, while the blades which are moving towards the inner portion of the machine will feather, so that the resistance is reduced to the minimum, and the blades or planes may pass-each other without danger of contact.

I The heads 43 are formed. at the outer ends of the shanks 45 that are carried by the blocks 46 which move within the'guides47 mounted on the frame of the machine. -.Adj u'sting rods 48connectfiwith the blocks 46 and are provided With-handles 49 whereby the adjusting rods maybe moved to adjust theshanks 45 andheads carried thereby, so that the arms '38 maybe caused to move the planes; or

blades44' tovarious' angles or: pitches, to 'conr-.

controlled by the trol the movements of the machine. Thus it will be obvious that when the planes or blades 44 operate in horizontal positions, the ma;

chine will be directed upwardly in a vertical line, but when the blades are moved, so that the side faces'thereof operate at oblique angles withrespect to the sides of the ma chine, the blades will tend to move the machine forwardly and upwardly.

The reference character 50 designates the gas bag that supports the weight of the mawill extendto thecompart'ment 52 in which the pilot-is seated. The landing gear embodies wheels 53 that are mounted at the lower ends of the arms 54, as clearly shown the drawings.v

Theoperatlon of device is as follows: The engines are started and ;.a -suitable chine, and the referencecharacter--51indicatesrthe rudder which is controlled in the usual and well known manner. The controls clutch mechanism1notshown is thrown into operation to transmit rotary motion to the cylinders. and planes .or; blades .s upported thereby. The planes or blades are; adjustedso that on their downward movements they will' be horizontal,- directingfjan upward thrust to themachine, and causingthe-mw; chine to ascend.) When the desired. elevation. has been reached, the planes or bladesare tilted totheproper angles to give-a-forward thrust to the machine, causingthe machine to move along, the speed of the machine being speed ofthe engines.
