NITED STATES PATENT OFFICE.

WALTER A. SUMAN AND GEORGE W. REICI-IARD, 0F PORTLAND, INDIANA, ASSIGNORS OF ONE-THIRD TO WILLIAMI F. MILLIGAN, OF PORTLAND, INDIANA.

AEROPLANE FLYING-MACHINE.

To all 'whom it may concern:

Be it known that we, WALTER- A. SUMAN and GEORGE W. REICHARD, citizens of the United States, residing at Portland, in the county of J ay and State of Indiana, have invented certain new and useful Improvements in Aeroplane Flying-Machines; and we 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 the letters and figures of reference marks thereon, which form a part of this specification.

This invention relates to new and useful improvements in aerial navigation machines and comprises an apparatus combining for safety the principle of parachute as well as aeroplane and so arranged that the planes, when not in use, may be folded to reduce the apparatus to a compact form for storage and other purposes.

The invention comprises various details of construction, combinations and arrangements of parts which will be hereinafter fully described and then specifically defined in the appended claims.

Ve illustrate our invention in the accompanying drawings which form a part of this application and in which Figure 1 is a perspective view from the rear of an aeroplane made in accordance with our invention. Fig. 2 is a perspective view showing` the front and one side of the apparatus. Fig. 3 is a front perspective view showing the aeroplane wings folded. Fig. 4 is an enlarged perspective view of the top of the apparatus showing the wings or aeroplane folded. Fig. 5 is a top plan view showing the wings extended. Fig. 6 is an enlarged detail perspective view of the forward part of the frame of the apparatus showing the propeller and shaft for driving the same. Fig. 7 is an enlarged detail perspective view of the vertically movable plane and mechanism for operating the same. Fig. 8 is a top plan view of one of the folding aeroplanes or wings. Fig. 9 is a detail perspective view showing the manner of holding the shaft bearing upon the frame of the apparatus. Fig. 10 is a detail perspective view showing the manner of holding the canvas to the ribs of the plane.

Specification of Letters Patent.

Application led December 24, 1909.

Patented Jan. 17, 1911.

Serial No. 534,885.

Fig. l1 is a cross sectional view on line 55 therefor, and Fig. 14 is a detail perspective 60 showing the connection between the tail rudder and lever for actuating the same.

Reference now being had to the details of the drawings by letter, A designates the platform of the car which may be of any shape or size. In the present instance a flat platform is illustrated having a -seatA for the operator and rear and forward axles A2 and A3 respectively upon which the wheels A4 are journaled. Rising from the platform are the upright bars B which are connected at their upper ends with the cross bars B and which are suitably braced and form the framework of the apparatus for supporting the aeroplanes and other operative parts of the machine. Projecting forward and inclining toward each other in advance of the car are the bars B2 which support a suitable bearing for one end of the propeller shaft C, the other end of said shaft being mounted in a bearing C upon the upper crosspiece of the frame, suitable brace rods C2 being provided which are fastened at their lower ends to the forward end of the platform and their upper ends adjacent to the bearing in which the forward end of the propeller shaft is journaled. Fixed to said propeller shaft is a propeller D of a well known and approved type commonly employed in aero navigation, and E designates a sprocket wheel which is keyed to the shaft C.

F designates a shaft journaled in bearings F adjacent to the forward end of the platform and having a sprocket wheel F2 keyed thereto about which and said sprocket wheel E the driving chain F3 passes. At the inner end of the shaft F is a gear wheel F4 which meshes with a gear wheel F5 fixed to the end of t-he motor shaft FG driven by any suitable type of motor, designated by letter F7, and which latter is shown in the drawings as mounted upon the forward part of the platform and within convenient reach of the seat thereon where the operator is adapted to sit for manipulating the apparatus in flight.

Upon the opposite side bars G of the frame are mounted the two folding wings, each designated by letter H, and each wing is made up of a series of ribs H which in practice should be made preferably of hollow tubular metal for strength and lightness and the canvas H2 of the wings or aeroplanes is provided with loops H3 at intervals and through which the ribs pass, a slight play being allowed between each rib at the ends of said straps to allow the wings to fold readily without interference or binding. The inner ends of the ribs are pivoted at I to the bars Gr of the frame and spaced apart and the outer ends of the ribs are securely fastened to the marginal edge of the canvas, as shown.

When the wings are opened out for flight, as shown in Figs. 1 and 2 of the drawings, a rope J holds the outer ends of the planes in the positions shown plainly7 in Figs. l and 2 of the drawings, in which position the wings are inclined upwardly, thus making it impossible for the wings to fold when thus connected together. In order to reinforce and distribute the strain coming upon the wings, wires, designated by letter-L, are fastened to each rib of the wings or aeroplanes at distances spaced apart and the lower ends of the wires fastened to the loops L which are fastened to the opposite edges of the car, said wires forming guy ropes and so arranged that the strain will be equally distributed and brought to the opposite sides of the platform and the bottom of the car and, where it is desired to concentrate the heavy portions of the apparatus so that by gravity the apparatus will normally be held right side up, the bulk of the weight of the apparatus will be compressed in the motor and the operator, the seat for the operator and the motor being so positioned that, when the operator is sitting in place to operate the machine, the center of gravity will be about at the positions opposite the fastenings of the guy ropes to the platform.

Pivotally mounted upon a rod or bar K fastened between the rear upright bars of the frame is a vertically swinging aeroplane or tail rudder N made up preferably of hollow tubular ribs N which are fastened at their forward ends to the rod or bar K and their outer ends to the end of said tail rudder. Midway the length of said ribs N are fastened the fingers N2 to which the brace or guy wires N3 are fastened, the outer ends of said wires being secured to the ends of said ribs, thus forming rein forcing means for said tail rudder. Mounted upon the cross-pieces at the top of the frame of the apparatus are the inclined bars O to which guy wires O are fastened and the outer ends of which are fastened to the ribs of the folding wings in the manner shown clearly in Figs. 3 and 4L of the drawings and which support the wings or aeroplanes when the same are spread.

Pivotally mounted upon the bracket members 7" upon the cross bar Q of the frame is a lever R which has pivotally connected thereto the bars R', each of said bars being pivotally connected at R2 to a socket member R3, a detail of which latter is shown in Fig. 14 of the drawings, and said socket member is fastened to a rib upon the tail rudder. Pivoted to the forward end of said lever R is a link S, shown clearly in Fig. 2 of the drrawings, which in turn is pivotally connected to the angle bar T at T', as shown clearly in Fig. 7 of the drawings, said lever R forming means within convenient reach of the seat to cause the tail rudder to be raised or lowered. Pivotally mounted upon said tail rudder is a laterally swinging rudder, designated in the drawings by letter M, the ribs h/ of which are pivotally mounted upon a rod M2 which projects at right angles from the rib to which it is fastened and is suitably braced by wires N 3. Cords M4 are fastened at M5 to the Opposite sides of the rudder M and pass about pulleys MC fastened to the ribs of the tail rudder and extend thence to the car where they pass about pulleys and are connected to the operating lever P which is pivotally connected at one end to the angle bar T. As both sides of the laterally swinging rudder N are connected by ropes to the lever P, it will b-e understood that, when said lever is swung in one direction or the other, the rudder M may be thrown to one side or the other accordingly as it may be desired in steering the craft, the vertical movements of the craft being determined by the tail rudder. By having the two levers mounted as shown and within convenient reach of the operator upon the seat, the steering of the craft may be readily accomplished and also the motor conveniently attended to by the operator.

W'hen our improved aerial navigating apparatus is adjusted for flight with the wings spread and held securely, it will be noted, upon reference to the top plan view Fig. 5, that the tail rudder which also acts as an aeroplane substantially fills the space intermediate the rear ends of the side wings or aeroplane, thus affording a large surface to be offered to the air in the event of the ma chine descending rapidly and, owing to the fact that the bulk of the weight of the apparatus is positioned at the bottom of the car, naturally by gravity the apparatus will be held right side up and would glide by gravity gradually to the earth in the event of the motor stopping, the descent of the apparatus being made gradual and similar to the action of a parachute, thus reducing the danger by accident to a minimum.

When it is desired to fold the aeroplane wings, it may be done by first loosening the rope J which, when the wings are adjusted for flight, is taut and holds the wings distended and the wings may be swung back to assume the positions shown in Figs. 3 and 4L of the drawings similar to the natural folding of the wings of a bird. Vhen the aeroplane wings are folded, it will be noted that the apparatus will be reduced to a compact shape not requiring commodious room for storage or shipment. By the construc tion shown, the wings may be readily spread to adjust the apparatus for flight.

Vhat we claim to be new is 1. An aeroplane flying machine comprising a car having an upright frame, a motor, folding aeroplane wings made up of fabric having straps fastened thereto, ribs having a loose play through said straps and fastened at their outer ends to the outer marginal edge of the fabric and their inner ends pivotally mounted upon the upright portion of the frame of the car at positions spaced apart, a vertically movable aeroplane tail pivoted at its inner end to the frame of the car, means for moving said aeroplane tail, a laterally swinging rudder upon the latter, means for operating the rudder, a propeller, and connections between the latter and said motor.
