, .To all whom it may concern:

Be it known that we, VINCENT DE DOMI- NICIS and FRANK A. HELP, citizens ofthe United States, residing at East Urange 1n the county of Essex and State of ew Jersey, have invented certain new and useful Improvements in Aeroplane Control; and we do herebydeclare the following to be a full, clear, and exact description of the into vention, such as will enable others skilled in the control of the ailerons, the elevators and the rudder so that the same may be grouped for actuation from a single stick.

The present invention dispenses with the rudder bar and with all wiring and cables an employed in other controls, and provides an improved unitary control for the various devices that is' easy and simple both in construction and operation.

In the accompanying drawings forming a part of this application, and in which similar reference symbols indicate corresponding parts in the several views: 1

Figure 1 is .a side elevational view with the parts in section and parts broken away at showing an improved control constructed in accordance with the present invention.

' Fig. 2 is a vertical sectional view taken on the line 2-2 in Fig. 1.

Figs. 3 and 4 show fraentary views of at details.

Fig. 5 is a perspective view with portions broken away showing one of the plans and the aileron connection; and

Fig. 6. is a perspective view with parts as broken away showing a tandem control.-

Referring more particularly to the drawv ings, 1 designates a tubular stick having its lower end forked, as iridicated at 2 in Fig. 3, the two branches of the fork being pivoted as indicated at 3 in Figs. 3 and t to'the opposite sides of a oke 4c. The yoke has trunnions 5 and 6 y which it may rock transversely in bearings 7 and 8 supported in any suitable manner on the aeroplane.

so The stick 1 is also capable of swinging longitudinally of the aeroplane on the pivots 3 without disturbing the position of the yoke d.

Arranged within the stick 1 is a rotatable shaft 9 having a bevel pinion 10 at. its upper end mesg with a bevel gear wheel 11 Specification of Letters katent. i

turned by a rotatable steering wheel 12 mounted in the upper end of the stick 1, the stick being hollowed out at the top portion to form a housing for the gears 10 and 11.

The lower end of the shaft 9 is coupled to a stub shaft 13 by means of a universal joint indicated at 14. The universal joint is in transverse alinement with the pivot pins 3 on which the stick 1 swings longitudinally and also in longitudinal alinement with the trunnions 5 and 6 of the yoke 4 on which the stick 1 s in transverse direction.

The lower end of the stub shaftisprovided with abevel pinion 15 meshing with a similar pinion 16 on a shaft 17 which runs longitudinally of the aeroplane and carries at its rear end another bevel pinion 18 in mesh with a similar pinion 19. The pinion i9 is fixed on'the rudder stein 20 and is adapted to turn the gudder to the right or left in accordance with the motion imparted to the pinion 19 from the hand wheel 12.

Tn this manner the control of the rudder is bad through the

shafts

9 and 17 from the hand wheel 12 carried by the stick 1 and such control of the rudder may be had at all "times, irrespective of the position of the either longitudinalor transverse directions.

A rod 21 is connected to the stick 1 and extends longitudinally of the aeroplane and in a rearward direction from the stick, the

rear end of the rod 21 carrying a bevel segment or half circle 22 rochng about a center 23 and engaging a bevel pinion 24: on a shaft 25 which carries a second bevel pinion 26 in mesh with a like pinion 27 carried by the elevator shaft and adapted to raise and lower the elevators 28 accordingly as the stick 1 is moved in a forward or rear direction. The rudder is indicated at 29. l

The front trunnion 6, as indicated in Figs. 1 and 4, is extended beyond its bearing 8 and receives a rocker 30 connected by rods 31 and '32 to the ailerons of opposite planes. Tn Fig. 5, the rod 31 is shown as connecting to a crank 33 which is secured toa shaft 34 journaled in the plane 35, which is para tially broken away to show the shaft 3 1.

The aileron is indicated at 36, and is pivotally mounted. in the plane 35 in the usual manner, the same rocking on and being fast me I and its aileron 36, the ailerons of the two planes being arranged for alternate operation by the

rods

31 and 32. This aileron control is therefore had by swinging the stick 1 transversely in either direction, which causes the yoke 4 to rock on the trunnions 5 and 6, transmitting a like rocking motion to the rocker 30.

In Fig. 6, we Ehave shown the device as useful in connec ion with tandem controls wherein 37 and 38 indicate two different controlling sticks connected to rock together transversely through a shaft 39 by which motion may be communicated to the rocker 30 when the stick 38 is swung transversely. In like manner a rod -l0 connects the two

sticks

37 and 38 so that the longitudinal swinging movement of the forward stick 3? may operate to pull or push the rod 21 and cause the operation of the elevators 28.

Furthermore, the shaft 17, which transmits movement to the rudder 29, is continued forwardly by an extension shaft $1 to the forward stick 3? where such shaft is turned by gearing similar to the gearing 15 and 16 heretofore described.

e claim:

1. In aeroplane control, the combination of a hollow stick, means whereby said hollow stick may be supported to swing both longitudinally and transversely, connections between said stick and the ailerons and affected only by the transverse swinging of said stick to cause adjustment of the ailerons, connections between said stick and the aeroplane elevators and adapted to be actuated only when the stick is swung longitudinally for raising and-lowering the elevators, a steering shaft journaled in said hollow stick, a steering wheel on the stick for turning said shaft, and connections between said shaft and the aeroplane rudder for steering the aeroplane from said stick, said last named connections including a universal joint for allowing the movement of the stick longitudinally and transversely without disturbing the rudder control, substantially as described.

2. In aeroplane control, a hollow stick, a yoke to which said stick is pivoted for lon gitudinal swinging, means for mounting said yoke for horizontal swinging together with said stick, connections between the yoke and the ailerons of the aeroplane, con-.

stantially right angles to the pivots of the stick and journaled to permit transverse swinging of the yoke and stick together, connections whereby transverse swinging of the yoke and stick may actuate, the ailerons of the aeroplane, connections between said stick and the elevators of the aeroplane for moving the same when the stick is swung longitudinally, a steering shaft journaled in the stick, means on the stick for turning said shaft, and connections between said shaft and the rudder of the aeroplane and including a universal joint in alinement with the trunnions of the yoke and the pivots on which the stick swings longitudinally, substantially as described.

4. In aeroplane control, a stick mounted to swing transversely and longitudinally, a rod connected to said stick and adapted to be moved forward and backward by the longitudinal swinging of said stick, a shaft, gear connections between said rod and shaft for turning the latter when said rod is shifted, and gear connections between the shaft and the elevators of the aeroplane for moving the same when the stick is swung longitudinally, a rocker adapted to be moved when said stick is swung transversely, connections between the ends of said rocker and the ailerons of the aeroplane, and steering apparatus carried by said stick and connected to the rudder of. the aeroplane whereby the direction' of the aeroplane may be controlled from said stick, substantially as described.
