AERONAUTIO APPARATUS.

SPECIFICATION forming part of Letters Patent No. 792,154, dated June 13, 1905. Application filed January 28, 1904. Serial No. 190,991.

To all whom it may concern:

Be it known that I, GEORGE MoMULLEN, a subject of King EdwardVII of Great Britain, and a resident of '77 Barrack street, Perth, IVestern Australia, Australia, have invented certain new and useful Improvements in Aeronautic Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention of an improved aeronautic apparatus essentially consists in the peculiar mechanical movement that is employed for the operation of the wings and which movement is of a combined oscillatory and rotary nature. This movement consists in the wing being fulcrumed upon a fixed pivot, while by means of a slot or opening formed in the side frame of the wing the latter is allowed to move or slide on and along such pivot. The wing also rotates on such fixed pivot or fulcrum, with the result that the wing during its rotation is in an everchanging position to and in respect of such fixed fulcrum, and consequently the wing performs a variable stroke and moves at altered velocities of beat during its rotation.

For the better understanding of the invention the same will be described by the aid of the attached drawings.

In the drawings, Figure 1 is a side view of the appliance, Figs. 2 and 3 being end and top plan views, respectively. Fig. 4 is a detail side view of the slot and fulcrum. Figs. 5 to 10 are diagrammatic views showing the positions which the wings assume at every sixty degrees of their rotation and also their position as regards the fixed fulcrum. In order to more easily follow the rotation and action of the wing, its last preceding position is shown by broken lines in Figs. 6 to 10. In such Figs. 5 to 10 the operative rod connecting with the main axis is also shown in broken lines.

Reverting to Figs. 1 to 4, the apparatus is suitably mounted upon a car or frame, as a,

of any approved design and construction, and this frame carries the motor a, also of any suitable design. From this motor and by means of pulley and belt a is transmitted the motion to the main shaft a and which latter is mounted on the frame, as shown. At each end of this driving-shaft a is keyed the cog-wheel b and which latter engages with its fellow wheel I), that is keyed on the rectangularly-arranged shaft 6 On this latter shaft is keyed the disk 0, to which is attached the rods 0. These rods at their other ends 0 are secured to the operative or small ends of the wings of the apparatus. This wing, as (Z, may be of any approved shape for purposes of suspension and progression and may be constructed of a bellied form or made to approximate in shape and contour to the wing of a bird. One of the side frames, as d, of the wing is formed with a longitudinal slot or opening, as d, in order to allow the wing to work on and along the fixed fulcrum, as d and which latter is rigidly secured to the main frame of the apparatus.

A rudder, as d, is provided for purposes of steering and navigation and operated in any suitable manner.

In the construction of the apparatus as a whole due regard and care would be given so as to insure lightness combined with strength.

The operation of the appliance may now be briefly described as follows: Upon the motion being imparted to the main shaft (15* and thence by the gearing b and b to the transverse shafts b and connecting-rods c the wings, as (Z, are made to rotate upon their fixed fulcrum or pivot (Z and in doing so they slide on such pivot, with the result that the wings have imparted to them a variable length and velocity of stroke or beat during their rotation. The wings perform their greatest beat or stroke between their positions as assumed in Figs. 7 and 8, respec tively. WVhen the wings attain sufiieient velocity, the apparatus will ascend and be sustained in the air and become navigable at the will of the operator.

hat I do claim as my invention, and desire to secure by Letters Patent, is

1. An aeronautic apparatus, comprising a frame, a Wing loosely pivoted thereon, and 1 means for causing the Wing to rotate and at the same time receive a continuously-varying longitudinal motion.

2. An aeronautic apparatus, comprising a frame having a pivot, and a rotatable Wing having an elongated slot into which said pivot passes.

33. An aeronautie apparatus, comprising a frame having a pivot, a Wing having a slot into which said pivot passes, and means for causing the Wing to receive a continuouslyvarying longitudinal stroke While rotating about its pivot.

4. An aoronautic apparatus, comprising a frame, a Wing loosely pivoted thereon, means for rotating said Wing, and means for simultaneously reciprocating said Wing.

5. The combination of a frame, a Wing loosely pivoted thereon, a motor on said frame, and connections from said motor to said Wing for rotating and reciprocating the Wing.

6. An aeronautic apparatus, comprising a frame, a rotatable Wing loosely pivoted thereon, and. means for guiding the Wing during its rotation to give it a longitudinal motion.

7. An aeronautic apparatus, comprising a frame having a pivot, and a rotatable Wing having an elongated slot into Which said pivot passes, said slot and pivot constituting a guide for giving the 'Wing a constantly-varying longitudinal motion during its rotation.

In testimony that I claim the foregoing as my invention 1 have signed my name in presonce of two subscribing Witnesses.

GEORGE Moh lULLEN.
