FLYING-MACHINE.

Specification of Letters Patent.

Patented sept. 24, 1907.

Application filed February 24, 1906. Serial No. 302,821.

To all whom it may concern:

Be it known that l, ANTHONY OBRATE, a citizenof the United States, residingat Enid, in the county of Gareld and Territory of Oklahoma, have invented a Flying-Machine, of which the following is a specification.

My invention relates to certain new and useful iinprovemcnts in flying machines.

The object of my invention is t0 so improve the Construction that the machine maybe caused to ascend to any desired height, to run horizontally or at any desired angle. may be caused to come down and land without difficulty, will be stable in the air and readily guided in any direction and in fact, to so improve lying machines that they will perform all the operations necessary for a practical and efficient machine of this character.

With these ob'jcctsin view, my invention consists iu certain constructions and combinations of parts, the preferred form of which will be first described in connection with thelaccompanying drawings and then the invention particularly point-cd out in the claims.

Referring 1o the drawings wherein the same part is designated by the same reference numeral wherever it occurs, Figure 1` is a side elevation partly in section of a machine embodying my invention. Fig. 2 is a section taken on line 2 2 of Fig. l looking in the direction of the arrow. Fig. 3 is a detail perspective view of what 1 term the balance propeller'. Fig. 4 is' a top plan view of the machine with the' aero-planes and balloon p removed.

1 designatesa bar which runs centrally of the niachine. I

2 designates side bars rwhich are connected to the bar l by means of the stuvts` or braces 5 so as to forma structure triangular in cross section, asshown in Fig. 4`

which constitutes the main frame of the machine.. The

ends o1" the bars 2 are connected to the ends oi' the bar 1 by means of the tension' rods 3. By this construction, a light frame is produced and one which will stand the stresses and strains placed upon it without buckling.

47 is a shalt extending transversely of the frame at about the center and it is mounted in suitable bearings on the bars 2 of the frame.

41 are the car supports to the lower end of which the car 100 is attached as shown in Fig. l, the upper ends of the supports being loosely journaled on the central transverse shaft 47 by means of the eyes 42 in the ends of the supports.

At the forward end of the car 100, I preferably provide a pair of supporting wheels 7l and at the rear end a wheel 72 mounted in a bell crank lever 73 pivoted at 75 to the car. I provide on the arm 74 of the bell crank 'lever a latch 76 by means of which the Wheel 72 can be raised or lowered in order to tilt the machine to assist in rising from the ground.

7 and 8 are after and fore propellers of my device, the propeller 7 being arranged at the stern and the propeller' 8 at the forward end or bow. These propellers are mounted in suitable bearing brackets 90 at the ends of the bar l. 91 are beveled gears on the shaft of the propellers 7 and 8 and 92 are beveled gears meshing with the gears 91, the gears 92 being supported in the brackets 90. 56 and 58 are pulleys mounted on the shafts of the gears 92 whereby the propellers 7 and 8 may be driven. shalt of the gear 92 for the propeller' 7 and the pulley 5S upon the shaft of the gear 92 for the propeller 8.

6-6 denote a pair of aero-planes which extend out from the main bar l and are of a length substantially equal to the length of the bar. These aero-planes preferably extend outward at an angle of about twenty degrees, as best shown in Fig. 2. The purpose of having the planes extend out at about this angle is that they operate to keep the machine upright or on an even keel, as, should the machine tip in one direction, the power of the plane towards which the tip occurs is increased, while the power of the other plane is decreased. This will cause the machine to right itself as will be evident.

Sl is a gas bag or balloon which may be used in connection with my device. The balloon preferably is cylindrical as shown and at its front end is of a cuneal shape to lessenthe air resistance. Preferably. the bal loon is not added to the machine until afl er i1 has been tested as if power of the motor and aero planes is suflcient to sustain the machine, then no balloon is necessary. Preferably and as shown. the balloon is set down as close'to the top of the aero-planes as possible.

As has been before stated, the shaft 47 is mounted transversely of the main frame at about the center thereof. The outer ends of the shaft are supported in brackets 93 which are stayed in position by means of the stays 94 secured to the frame and the stays 95 secured to the underV side of the aeroplane' 6. Mounted in cach bracket 93 is a shaft 97 which extends at right angles to t-he shaft 47.

48 and 49 are beveled gears secured to one end of each of the shafts 97, and 50 are beveled gears on the ends of the shaft 47 meshing with the gears 48 and 49 and by means of which the shafts 97 are driven. 9 and 10 are propellers mounted upon. the shafts 97. The shaft 47 is provided with a pulley 51 which is connected by means of a belt 54 to the drive wheel 53 of a suitable engine motor indicated at 98. The shaft 47 is also provided lhe pulley 5G being mounted on they with the pulleys 52 which are connected by means of the belts 55 and 57 t0 thc pulleys 5U and 58 for driving the propcllcrs 7 and 8. By this mechanism. the propeller-s 7. 8, 9, and 10 are driven in the direction to drive the machine forward.

15 is a shaft mounted in suitable bearings near the front of the car and 1st-14 are a pair of collars which loosely surround the'shaft 15.

19 is an arch bary the ends of which are secured to the collars 14. 13 is a second arch bary thc ends of which are also secured to the collars 1.4 and which extends out from the collars at right angles to the arch bar 19, as best shown in Fig. 3. 20 isa brace extending between thc middle portions of arch bars 13 and 1S) to hold the same in proper relation to each other.

79 is a bar extending between the sides of the arch bar 13 provided with a journal bearing 7S at about its middle. .lournaled in this bearing and in a bearing 101 at the center of the arch bar 13 is a shaft 12.

At the outer end the shaft is provided with what 1 term the balance propeller 11 and at its inner end with a beveled gear 1S meshing with a beveled gear 17 fast upon the shaft 15. The beveled gear 1S is also provided with a surface over which the belt 77 from the engine 9S passes whereby the beveled gear is driven.

21 is a cord one end of which is secured to the arch bat 19 and thc other to one end ola lever 22. This lever is pivoted at 23 and is provided with a latch 24 adapted to co-act with a segment in order that the lever may be held in any position of adjustment. By the operation of this lever, the angle of the balance propeller can be varied so that the force of the propeller will be exerted in the direction necessary to properly balance themachine or to aid it in its forward flight.

2S is a bai extending up from the rear of the car, to which is pivotcd a balancing plane 2G. To the plane is connected an arm 29, the outer end of which is connected to a lever 31 by means of the link 30. The lever 31 is fulcrumed at. 32 and provided with a latch 33 adapted to coperate with a locking segment.. By this construction the angle of the balance of the plane 26 can be changed to increase or decrease the lifting power at the tear end of the machine as may be necessary.

`ll5 is a bar extending outwardly from the forward part of the main frame of the machine and to this bar is pivoted a second balancing plane 27. Connected to the plane 27 at its pivot is a lever 36 which is connected by means of the cord 37 to a drum 39, the cord running over a pulley 3S loose on the shaft` 47. By the operation of the drum 39. the angle of the plane 27 can be varied to increase or decrease the lifting power at the forward part of the machine. By means of these two balancing planes and the balancing propeller thc mai chine can be so adjusted as to either fly upward. downt ward or horizontally. The dotted line `rl0 indicates the angle of adjustment which can be given to the plane 27 while the dotted line 3l indicates the angle of adjustment which can be given to the plane 26.

(i5 is a bar which extends downward from the main frame near the stern thereon and G4 are a pair of lugs mounted on the bar (t5 and spaced apart. Between these lugs are pivoted the riidder posts (iO-G1 carrying the double rudder 59.

G6 are a pair of arms. one extending out from the side of each of the rudder posts tiOwfil. To the arms 6G are attached the cords 157 which pass over pulleys (1S loose on the shaft Ht7 and downward to the winding drums (i9w70. By operating these drums. one or the other boards of the rudder will be swung outward which will cause the machine to turn in one direct ion or the other. By using the double rudder,` as described. it is possible by operating both of them at the same time and swinging both boards of the rudder outwardly to cause them to operate as a brake. It is, of course7 understood that the air pressure on the boards will cause them to assume their normal position assoon as the cords G7 are loosened on their drums.

45 are a pair of cords which are attached near the fore and after ends of the main frame and extend down to a winding drum 46 which is mounted on the supporting rods 41 of the car. By winding this drum in one direction or the other. the car is tilted either forward or aft under the aero-planes and the weight of the car is either thrown to the fore or after portion of the aero-plane. This will cause the aero-plane to tip upward or downward according to which direction the car is swung and assist in causing the car to rise or descend. 1t also assists in properly balancing the machine when running horizontally.

By the construction above described. 1 have produced a flying machine which is under full control. which may be propelled and accurately balanced and one in which all the operations necessary to successful Hight may be performed. I

While I have described what I believe to be the preferred form 0f my invention, 1 desire to have it understood that many changes may be made in the form. con struction and arrangement of parts without departing from the spirit of my invention.
