STEERING-GEAR FOR AEROIPIANES.

T 0 all whom it may concern:

Be it known that I. Ran: Tiuvirinn, citizen of the French Republic, residing at Paris, Department of the Seine, in. France,

simple,- novel and efficient manner. I

The invention is illustrated in the accompanying drawing, in which- Figure 1 is a diagrammatic view of one form of the-improved steering gear. Fig. 2 is a plan view of the same. Fig. 3 is a section on the line AA in Fig. 2. Figs. 4

and 4 represent a modification of the meansfor connecting the hand wheels withvthe tail. Fig. 5 is a plan of the device in Fig. 4. I

Fig. 6 is a perspective view of the rudder showing the manner of mounting the same on a framework and the relative locations of the actuating members.

The steering gear comprises broadly a movable rudder constituted by a

rigid frame

1, 2, 3, 4. preferably presenting the form of a triangular pyramid the apex l of which is directed rearward. The

frame

1, 2, 3, i forms the skeleton of the rudderand canvas or the like is stretched over all its faces in the usual manner. The pyramid 1, 2, 3', 4

ends at the rear in a supplementary surface 4. This pyramid is suspended from the fuselage of the apparatus at 4 by a ball and socket joint 5 or the like. The two

apexes

2 and 3 of the

base

2, 3, 4 are connected with the operating gearby ri id rods 6 and 7 provided at their extremi ice with universal or ball and socket joints. In the construction illustrated by way of example the gear comprises two hand Wheels 8, 9 arranged one above the other and carried by a tube 10 and by a tube 11 respectively, the tube 11 being arranged inside the tube 10. These tubes 10 and 11 may control the displacement of the rods 6 and 7 either directly or by the intermediary of reduciiig gear.

14 and 15 carry ing levers 16 and 17 to which arms 18, 19

carrying the extremities of the operating rods 6 and 7 are attached.

The steering gear operates in the following manner: The rudder may be given movements which will correct the apparatus when it has been deflected from its running pos'ition air currents by a variation of pres sure or any other cause. The apparatus is a then displaced in describing in the air a movement which approachesa helicoidal movement and which may be regarded as the resultant of three simple movements; the inclination of the longitudinal axis of the apparatus (pitching) oscillation around this axis (rolling) and deviation of the apparatus from its position which is termed stability of route. The steering ear described above permits of opposing isplacee ment of the apparatus and of corrccting it by imparting to the steering member movements-opposite in direction to those to which the apparatus issubjectedin enterin the current. In this case the hand whee are operate in the following manner. One of the hand wheels (the hand Wheel 9 for example) is turned in the proper direction; the rod 7 is displaced forwardand upward for example and the apex 3 of the rudder rotates in a plane perpendicular to 2, 4., the

point ft remaining fixedfl Therudder will then be displaced laterally and att-he same time directed upward, these efit'ects being proportionate to the lengths of the sides of thetriangle 8, 2 and .3, 4'. This ratio can be determined in accordance'with the characteristics'of the apparatus. The hand wheels 8 and 9 can also be acted upon in the following manner. If simultaneously with the displacement of the hand wheel '9 the hand wheel 8 is also rotated in such a manner as to modify the position of the point 3 a hclicoidal movement with variable characteristics will be given to the rudder. If the two hand wheels 8 and 9 be rotated through the same angle in the same direction the two rods 6 and 7 will he displacedequally in opposite directions one toward the front and the other toward the-rear and the rudder 1, 3, 4 will be displaced laterally in 'rotating about the joint 4. If the hand wheels 8 and 9 be rotated through the same anglctin opposite directions the rods 6 and 7 will be displaced together toward the frontor toward the rear theresult'being to displace it upward ordownward so that the a j brat-us will merely be caused to ascend or escend.

are mounted by the intermediary of bait 40' and socket joints upon levers 24, 25 ending in collars loose upon a fixed shaft 26 rig-id" with some conven ent part of the apparatus. It will be readily seen that this method ouE-= mounting prevents any lateral displacement of the rudder as aresult of gusts ofqvind acting'upon one of its faces while at the same time permitting of all displacements of the rudder by means of the operating hand wheels. If the hand wheels 8 and" 9 be rotated through the same angle and in oposite directions the levers'18 and 19 move 1n the same direction and the levers 23 and 24 rotate around the shaft 26 in the same direction. If the hand Wheels 8 and 9 be rotated in the same direction the levers 18 and 19 on the one hand and 23 and 24: on the other hand more in the opposite direction. If a single lever (the lever 18 for example) be displaced in the direction indic'ated by the arrow the extremity 2? of the operatmg trlangie moves to the left downward and 111 front 01: the plane of the figure because this ext emity rotates! around fixed lines 4, of ac o triangle of the rudder. the z WMMulataMv: WM WM t t v ocate? operating triangle having to move in a Similar manner the upper collar of the lever owing to a certain play that it has deecribee a helicoidal movement on the shaft so that the apex '22 moves'towar-d the left-downward and in front of the position that it-occupied. It should also be noted the connection of the two operating triangles perx'nitscf giving any desired displacement to-t-he collars of the lBVBI'SQd, 25 upon the shaft 26 without the tail being able to move otherwise than as controlled by the steering wheels.

33x1 the construction described a third hand .wheei 29 has been shown; this wheel acts by the intermediary of a tube 36 concentric wit; the other tubes upon a worm pinion By means of an appropriate system of levers 33, 34, 35 this imon controls the displacement of two w eels similar to the front wheels of anautomobile thereby enabling the apparatus to be steered on theground.

In order to prevent the tubes 10, 11 from accidentally influencingeach other these two tubes may be separated by an intermediate concentric tube not shown.
