Located at the forward 49 Figure 2 is the side elevation of the plane end is a detachable circular crosshead guide 3, 90 with landing wheels removed, showing in and inclosed in this lubricating case is plungparticuar the contrivance for manipulating er4. Aprojecting circular lug 10 engages the pivoted propeller in conjunction with plunger 4, connecting revolving toothed exstabilizing auxiliary wing around a circular tension rack 5, which meshes the toothed proguide, sheet metal fins, protruding from the peller root 6, which is held in position by 95 mouth of the main wing, shaped to a suitable socket 7, actuating adjustable propeller stream lined contrivance with its adjustblades 8 mounted `therein to vary the pitch ments for stabilizing the craft when in the or helix of propeller 8 by shifting plunger 4 air. Above the plane on the central vertical inclosed in tubular casing 3. Plunger 4 is 50 wing support or turret, machine gun is moved by rod 9, its threaded end engaging 100 lug 10. Rotating rod 9 is connected by means of universal joints 9 passing through the 'wall of crosshead casing 12, which extends transversely of said crosshead 4. Movement is transmitted to plunger 3 by extension rod -9 attached to hand wheel 14 located in convenient reach of operator thru suitably spaced universal joints on rod 9. Hand wheel 14 is adapted to manipulate the movement of plunger 4 which partly incloses pivoted motor shaft 15 mounted in ball bearings 16 and 17 securely attached to the revolving base of propeller socket 7 which forms the lubricating housing for the variable pitch propeller with its variation device mounted on the extension motor shaft 15, as .well as ball bearing 16, located in crosshead housing 12 -which properly attached prevents the loss of lubricating oil. Toothed lever 5 shifts in opposite direction, simultaneously varying the pitch of independent propeller blades 8 8. If it is assumed that the machine is taxiing on the ground its main wing 40 detached, varying the propeller blades 8 from neutral to any desired angle creates the desired power capacity, without the altering of motor speed, the rotating of hand wheel 14 manipulating the machine to the forward or rearward direction of flight, steering the machine to right or left on the ground. The steering mechanism of any suitable auto car may. be applied to the detachable cone, wheel base, part of a plurality of pontoons 41 4243, its novel design is the wheeled structure which serves to support the box tubing frame structures, front end steering wheels 39 39, and shift' rod 39 especially adapted for a farm to mar et vehicle. The rear end of fuselage 1x1 may be disconnected and a trailer may be attached to carry pay loads over highways.

Auxiliary stabilizing wing 44 is attached to guide 2. Slide 2a mounted on circular are 2 serves to hold propeller crosshead 3 and stabilizing wing 44 rigidly in shifting around the circular guide 2. A slotted box tubing frame makes up the stabilizing wing, its square shaped tubings 45 and 4'6 passing through circular arc disk, its slotted openings permitting tubes 45-46 to shift in the same direction of propeller 8 which is manipulated to any desired incidence of the flying machine. Extension motor shaft 15, at its extreme forward end engages revolving propeller socket base 18a by means of interior lug 18. The balanced base is provided with ballbearings 47 revolving in lubricating housing 3, the flow of lubrication being indicated byarrows. Intersecting joint head, revolving with ball bearing 19 inside bearing 3, casing 3, andrevolving head 18a serves to move the plunger and consequently shifting levers 5 5 and each toothed lever controls the movement of propeller blades 8 8 in the opposite direction. i

If an ascending flight is to be made hand wheel 51, in the hands of an operator is rotated and adjusting cables 53-54 are wound about drums 55 and 56. By rotating the wheel the propeller is adjusted around the circular bearing 2 which consists of two cast hollow box tubes which are fastened to the front end of cabin and are spaced apart so as to admit the extending motor shaft housing to move freely at the will of operator. This results in setting propeller 8, in conjunction with stabilizing wing 44, to a suitable angle ofincidence to make the ascension more rapid. Propeller blades 8 8 are adjusted accordingly, by means of hand wheel 14 transmitting rotating movement to rod 9 which is connected to universal joint 9*1 rotating threaded end in lug 10, which is attached to plunger 4. The interior of circular bearings form a runway for adjusting flexible cables 53-54 wound about drums S5-56, held in position by bearings 52 52. Larger diameter drums 60 6l, at the extreme ends of winding drum device, are in evidence and serve to operate the pivoted sheet metal fins (S4-65. Spaced box tubings 66 67 are for forming the stabilizing wing 68. The interior of these tubings are heated when at a high altitude preventing the exterior covering from icy coatings; for this purpose the central main wing support .69, located in the cabin constitutes a box tubing in vertical position, and adapted to furnish additional rigidity to the structure, and is a means to pivotally connect the main wing 40 thereon to be turned longitudinally with the fuselage when traveling on the ground. The interior of said box tubing support 69 may be utilized for a heating contrivance and the heated air is admitted to pass through pipes 70 71 into stabilizing wing 68 and the box tubing inserted in metal fins 64:-65 are shaplzd to a stream lined stabilizing wing 68 to be adjusted by means of cables 62 and 63, which are inclosed in a circular guide forming a runway for said cables to be attached to stabilizing contrivances to be shifted for simultaneously varying the incidence of the craft when in the air, stabilizing wing 44, manipulatlng in conjunction with wing 68 by rotating hand wheel 51. This adjustment is used to overcome the disturbing influence of dangerous air currents, nose dives or tail spins. The advantages'of this construction are evident, whereas other craft become helpless. In my invention it is merely necessary for the operator to adjust hand wheels 51 and 14 while the applying of rear elevators may be brought into service in normal flying, rudder of any convenient style preferable, steering the ship to right or left.

A number of elongated air or fuel tanks 41-42-43 serve to support the box tubing vframe structure constituting the pilots and passengers cabin and the various controlling I elements for the machine.

Pontoons 72- 73-74 are constructed from suitable light metal shaped in box style, its Hanged seams riveted to the cone fore and aft ends, welded seams preferred for landing wheel to be slipped on or removed by means of cotter key 77 or any suitablefastening device, rear ccntral wheel 77 may be attached in conjunction with front end landing wheels 39. Yokes or separators 80-80 two or more complete the wheeled truck or floating base of the machine. Additional braces 81-82 separate the vertical tubes 7 5-75-7 6-76, and the lower ends are securely fastened to flanged pontoons. `Wing supports 83-84 are used for a cross brace on both sides of the cabin when taxiing on the ground. Slotted box tubing 88 is used for the cabin and fuselage frame construction. A housing 89, a detachable power plant air cooling system with air passage 91 and a slotted box tubing 90 and a covering 89, make up the device, including separators or spacing blocks 98. In disclosing the construction of the slotted box tubing frame work end, view of tubing showing more particularly in Figure 6, end section of wing spar tubing 33 note V shaped impression 33" disclosing the advantage of having a secure hold of the inserted metal sheet covering 40. The filler 401 with its extending ends of sheet metal 64-65 has a corresponding V shaped impression meshing with 33" forming a self locking device, and the wing spar is made in two parts i bolted together by means of bolts 99.

Box tubing style is very eicient and suitable for all styles offrame work, a flanged tubing being vhand shaped open seam or welded, into a solid tubing of great strength. I have hereinbefore speclfically directed attention to my present invention disclosing the full and complete construction of a flying machine of the monoplane type covering novel methods in stabilizing air craft and creating a useful vehicle for road service by means of propulsion obtained from variable pitch propeller, reversing the machine in the direction of the desired flight eliminating the reversing mechanism used on auto cars.
