Specification. of Letters Patent.

Application filed April 20, 1911.

Patented .Mar. 26, 1912. Serial No. 622,263.

To all whom it may concern:

Be it known that I, HALVOR O. EIANE, a citizen of the United States, residing at San Diego, in the county of San Diego and State of California, have invented new and useful Improvements in Aeroplanes, of which the following is a specification.

This invention relates to improvements in aeroplanes and has particular reference to aeroplanes in which balancing planes are employed, which may be automatically controlled in accordance with the pressure of the air upon the side toward which there is a tendency for the plane to tip.

The presentinvention is especially adapted to aeroplanes of the biplane type and it is an object of the invention to provide an aeroplane with pivoted wings, said aeroplane also carrying an automatic vane or vertical plane so connected with said pivoted wings as'to right the machine in the event of its tendingto tip or skid.

It is also an object of the invention to provide a biplane with fixed supporting planes and ad ustable supporting planes and means for adjusting the said planes to effect the forward headway of the aeroplane.

It is also an object of the invention'to provide guiding means for the improved aeroplane and to connect the same with a universal operating lever for controlling the rising or falling of the aeroplane or the direction of its travel.

In the accompanying drawings forming a part of this specification, Figure 1 is a top plan view of an improved aeroplane emodying the features of the present invention. Fig. 2 is a side elevation of the same.

'Fig. 3 is a perspective view of the aeroplane lookin at the front ;portion thereof, the tail or ru der portion of the same being removed. Fig. 4 is an enlarged detail view showing a portion of the main frame in section, the automatic vane or vertical plane being shown in side elevation. Fig. 5 is a detall view of an enlarged scale showing the automatic vane or vertical plane in top plan. Fig. 6 in an' enlarged detail view in ront elevation showing the universal rudder vane actuating lever. Fig. 7 is a detail sectional view showin the mounting of said lever, a

ortion of tile bearing being broken away.

ig. .8 is a detail plan view of therear lever orarm carrying the automatic plane.

The details of the invention will now be more particularly described, reference being bad to the accompanying iliustration.

, the

,machine is preferably made ap to each other, are pivotally mounted upper main planes 4, the pivotal mounting of said planes being arranged nearer their forward edges than their rear edges, whereby the supporting air pressure beneath the said planes will tend to force the rear ends of the planes upwardly. Suitable means hereinafter described for holding the rear ends of planes against such pressure is employed. The framing at the central portion of the roximately plane 5 is rectangular portion rectangular and an upper fixe secured to the central of the frame. I l

The plane 5 and the portion of the plane 1 immediately below it are made narrower than the plane portions outside thereof, so that a space'is thus provided for accommodatinga propeller 6 which is carried by an engine 7 mounted centrally of the machine. The platform of the engine is usually supported about centrally of the height of the frame or a little below the same as indicated at 8 in Fig. 4. The movable main planes 4 are adjustably held in position by a series of cords or cables as 9, 10 and 11 arranged upon each end of the machine as clearly shown in Fig. 3. These cables pass downwardly to the front edge of the framing and thence over pulle s 12 to a common winding drum 13, pro erably mounted at a point near the front ed e of the aeroplane and centrally of its width. The drum 13 may be provided with an arm or lever 14 by which it may be turned for winding in the cables 9, 10 and 11, and thus depress the rear edge of the upper planes 4.

Outside of the upper planes 4 are pivotally mounted wing t1ps or planes 15 and 16 one being at each end of the plane supporting frame. These wing tip planes '15'and 16 preferably extend outside the end triangular frames 3 and the axial rods 17 and 18 upon which the said tip planes are pivoted are braced by diagonal brace. rods 19 and 20. The pivotal action of the said tip I is - of the main framing to a extend above the fixed upon the upper edge of planes 15, 16 is also forward of their centers as in the case of the planes 4 and the rear ends of said tip planes are adapted to be adjustably held against the pressure of the air, by means of cables or cords 21-and 22 which extend downwardly to pulleys 23 arranged at the rear e-dge of the lower framing as clearly shown in Fig. 3 and thence upwardly and forwardly to pulleys 24 secured to the front edge of the upper framing. The said cables thence extend to fastenings upon the opposite'surface of an automatic controlling plane or vane 25. The position of the said planes 15 and .16 is thus controlled by the movement and position of the vertical automatic plane 25. The said plane 25 forms an important feature of the invention and is preferably pointed at its forward end, while it is broadened toward its central portion its rear end being again reduced in height to plane 5 as clearly shown in Figs. 2, 3 andi'4. The forwai'd pointed end of theplane 25 is pivotally mounted in a yoke 26, the said yoke approximately fitting the contour of the point of said plane or vane 25. The yoke is pivoted at 27 upon a forwardly extending frame- 28 which projects from the upper portion point considerably in front of the same. The frame 28 is braced by an inclined frame 29 which extends upwardly from the lower rails of the main frame.

The frame 28' is of sufficient width to accommodate any lateral movements of the vane or vertical plane 25. The rear ends of the yoke 26 are pivoted to a rod or bar 30 which is secured to the vane 25 a short distance back of the front point thereof. The mounting of the front end of, the said vane 25 is thus of such a character that the point of the vane may swing fromside to side with the yoke 26 as said yoke moves on its pivot point 27 The rearend of the vane 25 is also pivotally mounted upon a swinging arm 31 which is provided with a vertical pivot pin 32 engaging .a bearing formed the main frame. The arm 31 extends rearwardly above theredge of the main frame. The arm 31 extends rearwardly beneath the edge of the vane 25 and is provided with an elongated slot 33 near its free end for engaging a depending pin 34 which projects from the said vane 25. Cushion springs 35 and 36 are mounted in the ends of the said slot33 so as to engage the pivot pin 34 in its movement in either direction. v

The cables 21 and 22 which extend to the vane 25 are connected thereto as shown in Fig. 5 at a point just forward of the pivot pin 32 of the arm 31. It will thus be seen that the movement of the vane 25 to one side or the other of the medial line of the aeroplane will Operate to pull one orsthe other of the tip planes 15 or 16 downwardly, the other plane at the same time being permitted to move upwardly to acorresponding degree. The plane that is moved downwardly at the rear will of course offer more resistance to the air upon the side. toward which the aeroplane is skidding and will tend to right the same. Upon the aeroplane reaching its normal balance once more, the forward movement thereof will tend to bring the vertical vane or plane into an intermediate position for restoring the tip vanes and pormitting the aeroplane to go forward upon an evenly balanced flight.

It will be observed that the automatic vane 25 is completely automatic in its operation in accordance with the way the machine tends to tip or skid and the tip' vanes are thuscontrolled without the attention of the aviator. The springs and 36 in the slotted arms 31 tend to cushion the action of the vane 25 as it shifts from side to side. The peculiar mounting of the said vane upon the pivoted yoke 26 and the pivoted arm 31 permits of the vane quickly adjusting itself to positions more or less parallel with the line of movement of the aeroplane. The frame 28 may also be provided with the usual forward horizontally arranged vanes or guiding planes as 40, theshape and operation of which forms no part of the present invention.

The aeroplane is guided by rudder or tail planes, there being preferably two in numher, one of which as 41 is arranged to operate in a vertical plane and is pivoted upon a' vertical axis at 42 while the other rudder 43 extends normally in a horizontal plane and is pivoted at a point'interme'diate its length, but somewhat nearer its front edge than its rear edge,-upon a pivotal'axis 44 supporting tions 45. The two rudders 41 and 43 are preferably operated by a universally operating lever 46 which is arranged .at the forward edge of the machine in front of the operator and is pivoted in the bifurcated end of a horizontally arranged ivot 47, the shank of said pin being mova ly mounted in a bearing 48 secured to the main framing of the aeroplane. The lever 46 extends below the bifurcated head of the pin 47 and is connected at its lower ends with cables or cords 49 and 50, which extend over pulleys 51 and 52 and thence rearwardly toward the rudders and around pulleys 53 and 54 to the rear edge of the vertically disposed rudder 41 to the rear edge of which they are fastened. It will be evident that by moving ing the horizontal rudder 43 a bar 55 is serearwardly extending frame por- A 'side or the other as required. For actuatcured to the opposite end of the bifurcated pivot pin 47 from the lever 46, the said bar being preferably extended approximately in a parallel direction to the lever 46. The upper and lower ends of said bar are connected by cables or cords 56' and 57 with the forward edge of the rudder 43, the upper cable 56 passing about apulley 58 to avoid the propeller 6, and thence over a pulley 59 from which it passes to the edge of the vane 43 as clearly indicated in Fig. 2. The lower cable 57 passes about a pulley 60 and thence to the forward edge of the said rudder 43, as also shown in said Fig. 2. .It will thus be evident that by rocking the pivot pin 47 by means of the lever 46, the bar 55 can be made to change the position of the horizontal rudder 43. In this simple manner the said lever 46 may be made to control the movement and action of both of the said rudders.

In using the aeroplane, it is driven in the usual manner by means of propeller 6 and the engine 7. The direction of the aeroplane is under the control of the aviator by means of the lever 46. In the event of the aviator desiring to make a quick and steep descent from the air, he not only directs the movement of the machine in a downward manner but operates the drum 13 to pull the rear edges of the main planes 4 downwardly so as to retard the forward movement of the machine materially and yet permit it to descend under proper control. The engine not being stopped will create enough of an air current to cause the rudders to properly direct the machine after it has lost headway. In the event of the aeroplane tending to tip and skid to one side or the other, the automatic operating vertical vane 25 comes into play pulling down one or the other of the tip wings 15 or 16 in accordance with the direction in which the aeroplane is inclined. The aeroplane will thus be automatically kept in a practically horizontal position by the action of said vertical vane 25 and the tip wings or planes operated thereby. v

What I claim is: I
