HLHUNHU l IUO Patented Dec. 17, 1929 waits a! JERRY I-IBSCHMAN, OF GREAT NECK, NEW YORK .AEROPLANE Application led October 27, 1927. Serial No. 229,192.

My invention relates to improvements in aeroplanes of the class shown in my prior United States Patent No. 1,025,063, dated April 80, 1912, in which the wings are pivoted to swing forward for rising, or rearward for descending or inaction, or one forward and the other rearward for turning in either direction.

In my said patent, the wings are shown 1o provided with independent handles for manipulating them and segmental locking devices for securing the handles and thus the wings in any position to which they may be adjusted.

My present invention consists of mechanism whereby the wings on opposite sides may be adjusted simultaneously te any required position by a single control, so as to insure the proper positioning of both wings with respect to each other in any desired adjustment.

To this end my invention comprises in its entirety a mechanism connecting the opposite wings by which they are simultaneously and harmoniously adjusted forward or rearward, another connecting mechanism by which one wing is moved forward and the other rearward simultaneously and harmoniously, a control and means for engaging the control with either of the two adjusting mechanisms substantially as hereinafter more fully set forth.

In order that my invention may be fully understood, I shall first describe in detail the mode in which I at present prefer to carry the invention into practice and then particularly point out the invention in the claims.

Reference is to be had to the accompanying drawings forming part of this application, in which like parts are designated by the same letters in all the figures.

Figure 1 is a plan view of an aeroplane of the class referred to provided with wing adjusting mechanism embodying my invention.

Figure 2 is a rear end elevation of the same.

Figures 3, 4, 5, 6, and 7 show various positions to which the wings of the said aeroplane may be adjusted.

Figure S is an enlarged detail view of the wing operating mechanism.

In the specific embodiment of my invention shown in the drawings, 8 designates the frame of the aeroplane; 9, 10 the vertical 55 posts to which the wings 11, 12 are pivoted by their respective hubs 13, 14; 15, 16 the lower guys, respectively, of the wings 11, 12, and 17, 18, the respective upper guys thereof, all substantially as shown and described in my prior Patent No. 1,025,063, before referred to.

To adj ust the wings 11, 12, simultaneously and harmoniously to any desired position by a single control, I in this specific embodiment of my invention, fix to the respective pivotal wing hubs 13, 14, bevel gears 19, 20.

The bevel gear 20 is engaged by a bevel gear 21, fixed on a transverse shaft 22, mounted to turn in bearings 23, fixed on the frame of the aeroplane, and on the transverse shaft 22, is fixed a worm wheel 24, which is geared to a worm 25 fixed on a shaft 26.

On the shaft 26 is keyed to slide axially thereon, but turn therewith, a spring pressed T5 wheel control 27, so that when the control 28 is turned the wing 12 may be swung to any of the positions shown in Figures 3, 4,

5, 6 or 7, for inaction, rising, straight flying, banllring and turning or descending, respecso tive y.

On the opposite end of the transverse shaft 22 is keyed to slide axially thereon, but turn therewith, a sleeve 28, on opposite ends of which are fixed bevel gears 29, 30 respective- S5 ly, and a clutch collar 31, engaged by an angle clutch lever 32, the other arm of which is engaged by the axially sliding wheel control 27.

The arrangement and adjustment is such that when the spring pressed wheel control is pressed axially rearward, the bevel gear 29 and not the bevel gear 80, will be engaged with the bevel gear 19 of the wing 11, so that when the wheel control 27 is turned, the wings 11, 12, will be swung simultaneously and harmoniously, one forward and the other rearward to any desired position, according to the direction and extent to which the wheel control 27 is turned. 100

When, however, the spring pressed wheel cont-rol is pressed axially forward, the bevel gear 3 and not the bevel gear 29, will be engaged with the bevel gear 19 of the wing 1l, so that when the wheel control 28 is turned, the wings 11 and 12, will be swung harmoniously and simultaneously both forward or both rearward to any desired position Iaccording to the direction and extent to which the wheel control is turned.

The aeroplane can thus be easily steered upward or downward or turned in either direcy tion by a single control in Convenient reach of the iyer on his seat .33. Owing to the worm gear preferably employed, the wings are automatically locked in any position to which they may be adjusted so that the flyer can remove his hands temporarily from the control wheel to use them for other purposes. f, 1t is evident that equivalent mechanism (d may be substituted for the mechanismherein described, without departing from the boundaries of my invention as defined by the following claims.

l claim as my invention:

l. An aeroplane comprising a frame, wings independently pivoted on opposite sides thereof, a wing operating wheel, operating connections between the wheel androne wing, reversible operating connections betweenv the wheel and the other wing, and means forreversing the connections between the wheel and the latter wing, so that both wingsI may be moved together forward or backward,.or independently forward or backward, vor one forward and the other backward.

2. An aeroplane in accord with claiml in which the reversible connections between one wing and the wheel comprise a wheel shaft on which the wheel slides but with which it turns, a wing operating shaft, gearing connecting the two shafts, reversible gearing between the operating shaft and t-he one wing, a clutch gear for reversing said gearing, and operating connections between the clutch Gear and the wheel sliding on the* wheel shaft.

In testimony whereof I aiiiX my signature.

JERRY HBSCHMAN.
