Patented Jan. 14, 1930 UNITED STATES- PAT-ENT OFFICE VALENTINE NEWBAUER, F LOS ANGELES, CALIFORNIA, ASSIGNOR TO NEWBAUER VERTICAL AIRPLANE CO., INC., A CORPORATION AEROPLANE Application filed January 14, 1928.

raise and lower the aeroplane in vertical lines, with the wings so driven that they coact with adjustably mounted side ailerons and also adjustable elevators in the rudder n group to maintain a relatively perfect equilibrium of the aeroplane that is fully under control of the pilot. That is the adjustable ailerons are connected to a stick control so that they can be manipulated by the pilot to positions best adapted to eEect a satisfactory equilibrium.

Another object of the invention is to provide a simple and effective means for navigating the aeroplane ina relatively vertical r line both in ascending and descending. To that end I provide each of the pairs of lifting Wings with four blades spaced equidistant apart with each blade formed with proper curves and cambers, and varying pitch angles and vacuum curves from the hubs to the outer ends of the wings to eect the greatest lifting power possible, with the Wings rotated ,in opposite directions so that their momentum in cooperation with the manually manipulated side ailerons and also the elevators at the discharge end of the troughs in the' rudder group will counterbalance and not cause the body to lose its equilibrium and the aeroplane spin or go into a nose dive or tail spin. Also Y this reverse rotation of the lifting wings effects a compound thrust to the air that aids greatly in a quick vertical rise of the aeroplane in a relatively straight upward course.

A feature of the invention is shown in the construction and arrangement of the side ranged transversely thereto and driven to Serial No. 246,768.

ailerons which are adjustable so that they shown in the construction and arrangement of the rudder group in which the elevators are adjustable to cause an upward or downward tilting of the nose of the aeroplane or hold the aeroplane in a balanced horizontal position.

Features of invention are shown in the construction, combination and arrangement of parts whereby' an aeroplane is provided that is neat and pleasing in appearance, easy to construct, assemble and operate, and which is safe and durable in use and effectively stabilized.

A feature of invention is shown' in the construction of the side ailerons, whereby they automatically move their respective elevator when they are manually shifted by a' pilot to laterally stabilize the aeroplane.

Other objects, advantages and features of invention. may appear from the accompanying drawings, the subjoined detailed` description and the appended claims.

The accompanying drawings illustrate the invention.

Fig. 9 is an enlarged fragvmental rear view analogous to that shown in ig. 8, showing the side ailerons shifted toward the right so that all the air thrust is on the right hand aileron and not on the left. Fig. 10 is a view analogous to Fig. 9' showing the side ailerons in a reverse position, and Fig. 11 is a fragmental vertical section through the body of the aeroplane showing the means for driving the lift- D inl wings in reverse directions.

gfhe aeroplane includes the usual body 10 with a nose and tail end, landing wheels 11, skid 12, rudder 13 and navigating propeller 14, it bein understood that the propeller 14 is driven by a usual aeroplane engine, not

' shown.

Mounted' on the top and secured to the body 10 is an extension 15 that supports the lifting wings 16, 17.l yThese wings are driven in opposite directions to prevent spinning the body 10 as well as for the purpose of aiding in stabilizing the aero lane. y t

As indicated' in ig. 11, the wing 16 is mounted on the upper .end of the hollow shaft 18 that is supported in the bearings 19 and 20; and a bevel gear 21 is secured to the lower end of the shaft 18 that is driven by a bevel gear 22 on the engine shaft 23, it being understood that there is a separate engine for driving the wings 16, 17.

The wing 17 is secured tothe upper end of a shaft 24that extends up through the shaft 18. This shaft is supported 1n the bearings 25, 26 and has a bevel gear 27 arranged oppositely to the gear 21 that also mesheswith the gear 22 so that when the shaft 23 is driven the wings 16 and 17 will be rotated in opposite directions.

Each of the wings 16 and 17 ispreferably provided with four wings or blades, but there can be more or less if so desired.

Each blade is formed with a heavy hub portion from which the blade extends to its tip end in varying pitch angles, Icurves and cambers such as have been found in practice to give the greatest lifting power possible.

. The contour, pitch angles and th'ilike are old and well understood lin the art and are therefore not shown or described in detail.

As stated, the lifting wings are arranged and driven in opposite directions for the purpose of compounding the downward thrust `on the air. That is, the air displaced by thel vwing 17 is againacted upon by the wing l16 so that the greatest lifting power is developed.

Thek great downward thrust on the air, in addition to lifting the aeroplane in vertical lines, is also utilized to stabilize it.

yAttached to the tail end of the body is a rudder group including the rudder 13 and troughs 28, 29 that are arrangedvso that a portion of the down thrust air from the wlngs 16, 17 vwillenter the' open inlet ends 30, 31 of the troughs and be deflected rearward to the open discharge ends 32, 33 adjacent to which a pair of elevators 34, 35 are pivotally mounted on a rod 36.

The elevators are mounted and arranged so they can be held in a neutral position, as shown in Fig. 3; and so they can be moved to`the dotted position a to .elevate the nose of the aeroplane or to the position b to turn the nose downward, or to any intermediate position between the positions a and b.

When the elevators are moved to the osition a their noses will engage the floor o the tail group and thereby cause all of the thrust .air to pass out above the elevators, which will cause the forward end of the aeroplane to be lifted upward into an ascending position; and when the elevators are lowered to the position b the thrust air is driven out under them which will cause the aeroplane to tilt downward into a descending position.

The elevators are operated by a stick control located in the cock pit handy to the pilot. This stick control is well known in the art and therefore is not shown or described in detail.

The stick control is connected by wires 37, 38 with the arms 39', 40 secured to the elevators 34, 35 so that when desired the pilot can raise or lower them.

The tail of the aeroplane is provided with the usual rudder 13 that is also operated in the usual way to guide the aeroplane laterally. Side ailerons 41 and 42 are slidably mounted on bars 43-44 that have their inner ends secured to the extension 15 and which extend laterally to the body 10. The bars arebraced by supports 45, 46, that extend from the wheel frame 47 to the bars.

The side ailerons 41, 42 are constructed, as best shown in Figs. 4 to 7, inclusive, and they are operated as best illustrated in Figs. 8 to 10 inclusive. As seen in the formen figures the ailerons are provided with transverse openings through which the outer ends of the bars 43, 44 extend an'd on which the) are slidable toward the ends ofthe bars or toward the extension 15 on the body of the aeroplane.

"-i-.The ailerons are moved by means of cords or pulleys 53 to the stick control in the cock pit and are arranged so that when the cords 49 are pulled in the cords V5() will be played out and vice versa.

The cords 49, 50Aextend over proper guides When the cords 49 are drawn in the side ailerons will be moved inwardly and vice versa. However, these cords are arranged to be actuated reversely to one another. That is when the cord 49 of the right hand aileron is actuated inwardly the cord 49 to the left hand aileron is played out and its cord 50 drawn in. In other words the cords are arranged so that when the right hand aileron is moved inwardly the left hand aileron is moved outwardly and vice versa.

The side ailerons 41, 42 are each provided with an integral extension 54 that is substantially the same length and general form as its associated elevator 55 except that the extension is only about one-third the width of the elevator. These extensions are to increase the area of the ailerons that are more directly affected by the air thrust from the wings 16, 17. That is when a side aileron is shifted to a position in which it will be affected by the air thrust the force will -be distributed over the inner surface of the aileron, including its integral extension.

The elevators 55 are secured by strap ,hinges 56 and a rod 57 to their respective ailerons and are arranged so that when the ailerons are moved inwardly7 the elevators are raised to aid in lateral stabilization of the aeroplane and when the ailerons are moved outward the elevators are tilted downward to also aid in lateral stabilization.

This tilting of the side elevators 55 is accomplished automatically. That is upper and lower arms 58, 59 are secured to the upper and lower side of the elevators and cords 60, 61 connect these arms'to pulleys 62, 63 secured to shaft 64 that are attached to their respective ailerons.

The ends of the bars 43, 44 are recessed at 65 and provided with elongated slots 66 through which the shafts 64 are extended and in which the shafts move when the ailerons are reciprocated.

Rack bars 67 'are secured in the recesses 65 and arranged to engage pinions 68 secured -to the shaft 64 s-o that when the ailerons are reciprocated or slid along the bars 43, 44 the pinions 68 will be turned to actuate the pulleys ,62 and 63 and thereby wind up one or the other of the cords 60, 61 and play out the other to move the elevators 55 either up or down.

The pulleys 62 and 63 are arranged so that when the ailerons are moved inwardly the cords 60 will be wound up to raise the elevators, and when moved in the reverse direction e, the elevators will be lowered.

Guides 69 on supports 70 are provided for holding the cords 60, 61 so they will wind and unwind on their respective pulle s.

In operation the wings 16, l; are driven to raise the aeroplane vertically and also when desired to permit it to descend in the same way but gently and gradually. In

other words when an ascension is to be made the lifting wings are driven at a relatively high speed to cause the aeroplane to quickly rise vertically'to any desired height, after which the speed is greatly reduced or to a speed that will not vfully overcoi'ie gravity and by means of increasing or decreasing the speed of the lifting wings the descent can be made as slow or quickly as desired.

After the aeroplane has reached a desired navigating altitude the forward or navigating propeller 14 is actuated to propel the aeroplane.

After the propeller 14 is put in action the speed of the lifting wings can be slight-ly reduced and driven for the purpose of stabilization, which, as previously indicated, is accomplished by a proper manipulation of the side ailerons and rudder group in cooperation with thelifting wings.
