JAMES MEANS, OF BOSTON, MASSACHUSETTS.

AERIAL NAVIGATION.

Specification of Letters Patent.

Patented Dec. 14, 1909.

Application filed March 10, 1909. '1 Serial No. 482,484.

e To all whom it may concern;

-Be it known that I, JAMES MEANS, a citizen of the United States, and a resident of Boston in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Aerial Navigation, of which the following is a specification.

My invention relates to aerial navigation, and more especially to apparatus for controlling and maintaining the longitudinal and lateral stability of flying machines and for steering thesame to port and starboard.

The object of my invention is to provide certain improvements in apparatus for operating a flying machine as hereinafter more fully setv forth.

""lflyinventioifwh, ichu's an improvement on the contro'lhng apparatus" described in my application Serial No. 418,679, filed March 2, 1908, will be described in connect1on wlth the accompanying drawings, in

v which- Figure l is a side elevation of one embodiment of my invention; Fig. 2 is a secthe ar and rack J and. I in the other.

1 rod tion taken on the line 2-2 of Fig. 1; and Fig. 3 is a plan view on an enlarged scale of a portion of the controlling apparatus.

In that particular embodiment of my invention selected for illustration for the purpose of more fully disclosing the principle thereof, A is a rod or tube secured in any suitable manner to the frame of a flying machineand placed parallel to the direction of flight indicated. by the arrow.

C is a fork. integral with the tube B which surrounds the 'rod A. and H is a lever terminatin in the fork H which is pivoted to the ork C and to which the gear G is rigidly connected. The lever H may be weighted in any suitable manner such for exampleas by the: vertically adjustable bob D, inwhich case the leyer operates as a pendulum. As hereinafter more fully explained, my invention contemplates the use of said lever'as a lever operated manually or as a pendulum operated partly automatically and partly manually.

The-rod E which is carried by the support E is connected with the pendulum H and the longitudinal rudderK through the gear and rack G and F in theone case and The connected by the loose coupling L. The

preferably is divided into two parts shown in Fig. 1, are actuated by the rotary movement of the tube B through the beveled gears M and N, the gear Mbeing secured to the tube and each rudder Q, being connected with a gear N.

U is a vertical'rudderfor steering the machine to port and starboard, and is connected through the gears T T and the rod S, a portion of which as shown at S is flexible, with the handle or handles 4, 5. The lower portion of the rod S is secured to the lever H by the arms 1, 1, and the fork 2, 2 is connected with said rod S through the head 9 by which the flexible portion S of said rod is connected to the lower portion usual. form of bicycle steering handles at a *point above the pivot or point of suspension of the lever H. A. plurality of such handles may be employed if desired and in the present' instance I have shown two such handles connected in tandem by the rods 6 6. The

' auxiliary handle 5 may be'pivoted as shown at 7 to the fork C which is integral with thetube B. In this case the fork 3 which terminates in the boss 3 extends upwardly and terminates in a cross-piece 10, and the handle 5 is pivoted as shown at 8 to said cross-piece. V

The operation is as follows: Assuming the wholly automatic operation of the controlling means by the weighted lever or pendulum, the relative movement between the machine and the pendulum caused by the pitching or rolling of the machine will efi'ect such movement of the longitudinal and lateral rudders as to steer the machine back into a horizontal position. If the front part of the machine pitches-downward, a clockwise rotation of he rudder K will be produced through the intermediary of the gear and rack J and I and the rudder will receive the greatest air pressure on its upper side thereby steering the machine into a longitudinal course. In like manner, if the front part of the machine pitches upward, a counterclockwise rotation of the rudder K will be produced and the rudder will receive the greatest air pressure on its under side thereby steering the machine into a horizontal course. If the lateral stability of the machine is disturbed, the weighted lever or pendulum will swing transversely to the direction of flight of the machine and the tube B will make a partial revolution around the cient weight to make the necessary motion,

and the operator profiting by the indication made by the pendulum will check any tend-- ency to erratic movement by means of the manually-operated device. By experience,

the movements of the handle necessary to maintain the stability of the machine will become instinctive in much the same manner that the experienced bicyclist maintains the upright stability of his machine instinctively and without thought. Therefore when the operator has learned to balance a flying machine, the weight may be removed from the lever H, so that the same will no longer operate as a pendulum. It is advantageous to use the device H as a lever and not as a weighted pendulum because the weight of the pendulum, although necessary for auton'iat-ically effecting the relative movement necessary to actuate the lateral and longitudinal rudders may tend to accentuate the pitching or the rolling of the machine.

The salient feature of my invention resides in the position of the operating handle or handles 4:, 5, at a point above the pivot of the lever H, because when so located the movement thereof is opposite to that of said lever and is in the direction toward which the operator instinctively moves when the balance of the machine is affected. For instance, when the machine pitches forward, the operator instinctively leans backward, and if the manually'operated device is so located that its backward movement will produce a clockwise rotation of the rudder K, the machine may be more readily righted than if the operator, whose tendency is to lean backward when the machine pitches forward, were obliged to grasp the .lower part of the lever H and push the same forward. In like manner when the machine rolls toward the operators right his tendency is to lean toward the left, and it will be seen that ifhe moves the handle 4 to the left, thereby creating a counter-clockwise rotation of the tube B, the lateral rudders Q, will assume positions tending to restorethe machine to hori'zontality.-

One of the objects in employing two or more tandem connected manually operated devices is to enable an experienced operator to teach an inexperienced onezthe art of.

balancing a flying machine, and another object "of this construction is that more even and graceful flight will be effected if all the persons carried by the machine simultaneously assume the same positions and make the same motions and by their combined weights assist in preserving the equilibrium of the machine.

In order to steer the machine to port and starboard, the vertical portion of the rod S is arranged to turn in supports 1, 1 and the rotation of said rod which is effected by the handle 4: is communicated to the rudder U through'the gears T T. Through the rods 6, the handle 5 is turned about its vertical ivot 8 in correspondence with the movement of the handle 4 about the centers of the bearings 1, 1.

It will be understood that the particular apparatus hereinbefore described may be subjected to a wide range of variation by those skilled in the art without departing from the spirit ofmy invent-ion.
