FLYIhT G-MACHINE.

Specification of Letters Patent.

Patented April 27, 1909.

Application filed July 1, 1908. Serial N 0. 441,334.

To all whom itnna'y concern):

Be it known that I,RUD0LPH GzDRESSLER, a cltizen of the United States, residingat' Coney Island, in the county of-Kings and new and useful Improvements in- Flying- Machines, of which thefollowing is a specification.

This invention relates to improvements in flying machines of that type which are inerates both the propelling'and steering devices; and for this purpose the invention consists of a flying machine comprising an upright supporting frameyan aeroplane supported at the upper part of the frame, os cillating wings hinged to the framebelow the aeroplane and extending at both sides of the same, said wings being provided with i movable blades that swing above the wings during the downward motion and below the wings during the upward motion of the same. lever mechanism for imparting oscillating motion to the wings. a steering rudder located at the lower front-part of the frame, and mechanism for setting the'rudder into the required position.

' The invention consists further of certain described hereinafter and finally pointed out In the accompanying drawings, Figure l represents a perspective View of my imstarting it, Fig. 2 is a front-view of the same; drawn o'na smaller scale, and Figs. 3 and 4 are perspective views of the blades on the outer ends of the wings, showing] them in posit-ion respectively at the com mencement of the downward and upward strokes.

Similar letters of reference indicate corresponding parts.

Referringto the drawings, a represents 1 an upright frame which is provided with a at the lower end, said platform ing it over ,the ground. The upright frame z is composed of two pairs of inclined and intersecting frontand rearrods a which are stiffened bysuitable braces 0* that are e frame. The upper end of the frame is susp nded by thin steel wire ropes a which are connected at their 11 per ends by a short shaft b carrying a ro ler 5 so as to permit the frame to be suspended from a horizontal rail 1, which is slightly curved in downward direction at the outer end, as shown in Fig. 1. The roller 7) passes over the rail T when the flying machine is to be started. The person who desires .to use the flying machine takes his stand on the platform a. when he desires to work the machine with his arms or feet.

. On the upper part of the supporting frame a at the point where the upper ends of the intersecting rods are connected by the bracerods a is arranged an aeroplane at which is supported at an oblique angle of inclination to the horizontal plane and formed of transverse convexo-concave sections constructed of a frame of thin steel or other tubes that are connected by oiled silk and canvas or other suitable waterproof material. Below the aeroplane (Z are arranged two curved f wings -w-which are hinged at their inner ends to the supporting frame at thepoint of intersection of the frontand rearrods 0..

The wings in are made considerably larger than the aeroplane, of light'ribs of ratan. steel or other material, and covered by oiled silk, canvas or other waterproof fabric. The

wings w are operated by levers Z that are pivoted to the under-side of the wings and connected with a combined handle-and-foot rod 1 which is moved up and down by the hands or feet. of the person using the machine so as to impart oscillating motion to the wings.

. Atthe outer ends of the curved wings w are arranged a series of movable blades j. which are made of a light frame and oiled silk webbing and hinged at one side to the ribs of the wings, While the opposite sides of the blades are connected by thin yielding wire or other strings f with the ends of the adjacent ribs, so that during the upward motion of the wings the blades are moved in downward positlon and held at a suitable angle of inclination 1 below the wings, as shown in Fig. 4, while when the wings are moved in downward direction the blades assume a position abovethe wings at a suitable angle of inclination to the same.

When the machine is. placed a ainst the Wind and the operator moves t he raised Wings from their highest point downward by means of the lever-connections, he places his shoulders against two shoulder-rests '72. so as to obtain more strength for the first few ascending strokes. The shoulder-rests h are connected by curved rods 72, with the sup-.

. of the frontand rearrods. The wings will then assume a partl concave and partly convex position and t e' movable blades, being held in position by the wire strings, will rise to about an angle of 25, giving thereby forward propulsion to the machine, while at the same time the wings lift the structure off the ground. At the same time as the forward motion is imparted, the aeroplane, which is located above the wings, assists, owing to its angle of inclination, in lifting the machine off the ground/and prevents it from descending during the next upward stroke of the wings. The movable blades drop down during the up-stroke of the wings into a corresponding angle to the wings, but below the same, and assist thereby the forward propulsion, the wings assumin then a convexpconcave position, as shownby the lower dotted lines in Fig. 2, which prevents the machine, in conjunction with the aeroplane, from being moved in downward direction, as shown. I

In front of the frame a, is arranged a steering rudder 1- which is pivoted to an uprightfirod 0" that is connected with a horizontal rod T which is attached to the platform a, the inner ends of the rudder being connected by suitable ropes 1" passing over pulleys r with the lower art of the frame so as to be readily operated by the hands of the person using the flying machine. By

pulling the rope r at one side the rudder is moved in one direction and by pulling the opposite rope 1 the rudder is moved in the other direction, so as to steer the flying ma-.

chine thereby. As the weight of the operator is in the center of ravity of the entire structure, a perfect equilibrium is obtained, so that even when the wings are not oper ated, the person operating the flying machine and the structure itself are enabled to soar in the air like a parachute so as to permit the gradual descent of the flying machine, even if some of the wings should become injured or broken, the structure acting then in the nature of a life-saving apparatus. i

Instead of operating the lever mechanism by the hand or foot,- a small motor may be used for actuating the same, which would then leave the hands free for operating the starting of the motor and the steering rudder.

T he movement of the wings in connection with the opening and closing of the blades during the upward and downward motion of the wings, produces the forward propulsion, lifting and soaring of the machine in an eflective and reliable manner, forming thereby a flying machine of small size and cost, which can be operated with absolute safety, with or without power, in flying, soaring, ascending and descending.

Having thus described my invention, I claim as new and desire to secure by Letters Patent: v

1. A flying machine comprising an upright supporting frame having a platform at the lower end, an inclined aeroplane at the upper end, oscillating wings below said aeroplane, and movable blades on the wings adapted to move up and down with the downward and upward motion of the wings.

2. A flying machine comprising an upright supporting frame, an inchned'aeroplane at the upper end of the same, oscillating wings below said aeroplane, means for oscillating said wings, and movable blades at the outer ends of the wi and up during 0 upward and downward motion of the wings. I

3. A flying machine comprising an upright supporting frame, an inclined aeroplane at the upper end of the same, oscillating wings below said aeroplane, means for oscillating said wings, movable blades fin the wings adapted to swing'down and up during the upward and downward motion of the wings, a steering rudder supported at the frontpart of the frame, and means for operating the same.

4. A flying machine comprising an upright supporting frame provid witha platform at the lower end, an'inclined aeroplane stationary on the upper end of the frame, said aer lane being curved in transverse direction, oscillating wings below said aeroplane provided with movable blades'on said wings, means for actuating said wings, a steering rudder located below the wizwsfand means for operating the same from the supporting frame. Y I p 5. A flyin machine comprising an upright supporting frame, a fixed inclined aeroplane at the upper'part of the frame, and oscillating wings hinged to the frame below the aeroplane and provide with flexible ribs and movable blades'lo ween the ribs, said wings assumin a partly, concaveandpartly convex shape during the down-stroke and a convexo-concave shape during the up-stroke. In testimony, that l claim the foregoing as my invention, I have signed my name in presence of two subscribing witnesses.
