FLYING-MACHINE.

Specification of Letters Patent.

Patented Sept. 20, 1910.

Application filed February 25, 1910. Serial No. 545,910. a

To all whom it may concern:

Be it.known that I, PETER RoBERT TOR- BRAN a,citizen of the United States, residing at Denver, in the county of Denver and State of Colorado, have invented new and useful Improvements in Flyin -Machines, of which the following is a specification.

This invention relates to flying machines, and particularly to improvements in means for steerin the same horizontally and vertically and automatically correcting the tendency of the machine to tilt unduly in any direction, so as to maintain the balance or equilibrium of the machine. a

The object of the invention is to rovide simple and effective steering and ba ancing means under control of the operator for normal steering purposes and automatically operative to restore the equilibrium of the machine when the latter tilts in any direction to an excess degree.

The invention consists of the features of construction, combination and arrangement of parts hereinafter fully described and claimed, reference being had to the accompanying drawings, in which Figure 1 is a perspective view of a steering and balancing mechanism embodying my invention. Fig. 2 is an irregular vertical transverse section thereof, on the line 2--2 of Fig. 1. Fig. 3 is a vertical transverse section through the slotted arm of the bell crank lever and adjacent portion of the frame. Fig. 4 is a detail section on the line 4-4 of Fig. 1.

Referring to the drawings, 1 designates a supporting rod or bar forming a portion of the frame of a flying machine, only so much of which is shown as is necessary to illustrate the construction and principle of oper- Pivotally mounted to swing on a vertical axis at the rear of this rod or .bar is a rudder orsteering plane 2, for laterally steering the machine. Horizontally mounted to swing on a vertical axis at the forward end of the rod or bar is a rudder 3 for steering the machine in a vertical plane. These rudders or their shafts are res ectively provided with'crank arms 4 and 5, or a. purpose hereinafter described.

The rod or bar 1 preferably consists'of two sections united by a four-armed coupling 6, which connects therewith a fixed hollow transverse rod 7, in the opposite endsof which are journaled rods or shafts 8 and 9,

respectively, carrying stabilizing balancing or leveling planes 10 and 11, the construction being such that the two planes may be oscillated in a vertical direction by the rotar movements of the shafts 8-and 9.

U-shaped bracket or han er 12 is arran ed below the coupling 6 an is provided wit sleeves 13 loosely engaging the shaft 7 on opposite sides of said coupling, and in the horizontal or cross ortion of said bracket is formed a longitudmal slot 14. A stem 15 projects vertically through the slot 14 and is connected at its upper end by a universal joint 16, to the coupling 6 and carries at its lower end a head or weight 17, which normally occupies a horizontal position and preferably consists of a disk having its edge beveled to reduce its resistance to the atmosphere. 7

The stem and its head form a pendulum arranged in line with the center of gravity of the machine and adapted by its connection with the bracket 12 to swing in a fore and aft direction with said bracket, and to swing laterally in the slot 14 independently of the bracket.

An 0 crating lever 18, arranged in practice ad acent to the aviators seat, is pivoted at its lower end, as at 19, to one of the sleeves 13, the pivotal connection being such as to permit'the lever to swing transversely or laterally only independently of the bracket, the lever being also movable in a fore and aft direction longitudinally parallel with the, rod 1 to swing the bracket 12 accordingly. Mounted upon the rod 1 adjacent to and in rear of the lever is a hearing 20, upon which is fulcrumed a bell crank lever 21, one of the arms 22 of which is pivotally connected by a rod 23 with the crank arm 4 of the vertical steering rudder 2. The other arm 24 of the bell crank lever. is provided with a longitudinal slot 25 through which the lever 18 extends, and which slot is of proper length to permit of the fore and aft movement of the lever without influencing said bell crank lever and the vertical rudder. The-side walls of the slot- 25 are V-shaped in cross section. to permit the lever 18 to assume different angular lateral positions, the construction being such that the lateral movement of said lever in one direction or the other will cause a corresponding movement of the rudder 2. The stem 15 is pivotally connected at one end,

It will thus be understood from the foregoin description that the aviator by swinging the lever 18 in a lateraldirection may operate the vertical steering rudder 2 and by swinging said lever in a fore and aft direction may operate the horizontal steering rudder 3, without in an manner affecting the balancing and levellng planes 10 and 11, which are automatically controlled by the pendulum to maintain the lateral balance of the machine. In order to effect the actuation of these planes from the move-- ment of the pendulum, or, more strictly speaking, the movement of the machine relative to the pendulum, a rope or cable 28 is fastened at each end to the stem of the pendulum and, thence, extends in opposite directions and passes around actuatlng pulleys 29 fixed to the shafts 8 and 9 of the planes, the stretches of the cable also passing adjacent each actuating pulley around suitable guide pulleys '30 mounted on the ends of the main shaft 7. It will thus be understood that ifthe machine should tilt to an excess extent for-- wardly or rearwardly in one direction or the other, the front rudder 3 will-be auto matically adjusted to correct the tilting tendency, while if the machine, should tilt to an undue extent laterally, motion will be transmitted through the cable to reversely swing-the planes 10 and 11, the balancing plane on the hi h side bein drawn downwardly and'the alancing p ane on the low side swung upwardly, so that the pressure of the air against the surfaces of these planes will restore the machine to a normal position.

Having claim 1. A flying machine including a horizon-v tal rudder, a vertical rudder, lateral balancing planes, a fore and-aft swin 'ng element, a gravity-controlled univer'sa ly-movable, member operativel connected wlth said horizontal rudder an e balancing planes, said member being movable in a fore and aft direction with said swinging element to control the horizontal rudder and movable laterally independent of said swinging the bracket, operatin described the invention, I

and in a different direction independent of ,said element and member foroperating the upon the frame, tilting laterally balancing planes mounted upon the frame, a yoke bracket pivoted to the frame for a fore and aft swinging movement and having a slot therein extending transversely of the frame, a pendulum universally jointed to the frame, said pendulum being movable laterallyiin said slot independent of the bracket and .movable in i fore and aft direction with connections between the pendulum and t e horizontal rudder and between said pendulum and the balancing planes, a bell crank lever mounted upon the frame and having a longitudinally slotted arm, a connection between the vertical rudder and other arm ofsaid lever, and an operating lever pivotally connected for lateral movement upon the bracket and extending through the slotted arm of the bell crank lever, said operating lever being movable fore and aft in said slotted arm to swing the bracket laterally of the shaft and bell crank lever without affecting said bracket.

3. A flying machine including vertical and horizontal steering rudders, lateral balancing planes, a pendulum, an operating connection between the pendulum and the horizontal rudder, operating connections between the pendulum and the balancing planes for simultaneously adjusting the latter in opposite directions, and a lever operatively connected with the pendulum for adjusting the horizontal rudder Without afiecting the balancing plane and operatively connectedv with the vertical rudder for adjusting said rudder without afi'ectin'gthe horizontal rudder or balancing planes.

4;.
