To all whom t may concern.'

Be it known that I, GEORGE lV. LYNN, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented new and useful Improvements in Flying-hfachines, of which the following is ay specification.'

This invention relates to flying machines of the heavier than air type, and consists in the novel construction, arrangement and combination of parts hereinafter more fully described and claimed, reference being had to the accompanying drawings, in which- Figure l is a side view of a device embodying the invention. Fig. 2 is a detail of one of the lifters and its mountings. Fig. is a detail view of the rear propellers and rudder and their mountings and control. Fig. 4 is a detail of the frontl propeller and its mountings and control. Fig. 5 is a detail of the operating levers and their mountings, and Fig. G is a `detail of the power transmission control.

As shown in Fig. l, A is the platform constructed of any desired material that will allow of its being light in weight but strong and rigid in structure, and built in any suitable manner but with its front portion al given a parabolical curve upward to assistvits dynamical reaction in impinging -on the ocean of aerial gas through which it passes. Besides performing the function of a platform on which are properly positioned the operator, motive power, and superstructure, it performsthe multiple function of assisting the liftersto raise the flying machine when desired, of sustaining the flying machine alone when desired, or of acting as a parachute when desired, all by means of the operations and' parts hereinafter more fully described. y

B denotes the lifters, preferably four in number as shown in the drawings.

C are the rear propellers, D the rear rud# der, E the front propeller, F the lever controls, G the power transmission clutches.

As shown in Fig. 2aB are the lifters. Each lifter is composed of four sections or blades 1, b2, b3, and bt, which are respectively pivotally connected to the mounting cr shaft H, which is hollow, and is supported in position by the pole brace h4. tion is reduced against this pole brace by means of ball bearings h5. The pole brace is embedded in the platform A. Each sec-v tion of the lifter is composed of any suitable Fric lightbut strong materials and is built in two parts 715 and be. so as to give a straight surface which is retained in this relation by means of bracing ribs ZF. The part 56 acts as a fence or curbing to the part b5 and is built to symmetri- The part b5 is built i cally follow the edging of part If and to deone-third of the distance between the outer edge and the pivot lug are two operating rods fr and o1". is rigidly fastened to an integral sleeve h1 mounted on the lifter shaft H, so arranged that it will depend at an angle ofI about 45. The rods Z910 are likewise fastened to a sleeve f1.2 by means of flexible connections. sleeve 7b2 is allowed to slide up or down along shaft H. This sleeve h2 has connected to it an operating rod 71,3 suitably directed from the operators seat by means of right angle yokes h4. T he operating rod h3 has its sleeve connecting end arranged in the form of a Y yoke, through the ends of which are run fastening pins or pivot lugs By thisl means a flexible connection is made which allows of the angle of incidence of each of the sections b1, b2, b3 and 2)* of the lifters' to be changed as is desired so as to perform the functions of a lifting propeller or helicopter, or to maintain a The rod 7) of each sectionA Said Y sustaining surface to assist the platform sur# face A in keeping the flying machine aloft or to act as a parachute to break the fall of a quick landing.

Z2 are superposed bracing rods placed across the center of the upper surface of each section b, b2, 3, b4.

Each of the rear propeller-s is mounted upon a horizontal shaft c1 in the same manner and operating under the same principles as the lifters. Thus C2 is the main section of each propeller blade. braced by ribs c3, while c4 is the pendant section along the edge, which is formed at right angles to partc2.

c5 are operating` rods-flexibly connected to the forward surface of the propeller and Vward surface of the propeller part c2 about one-third of the distance'from the edge, one near one side edge and the other rod near the middle. lunning from proper control levers at the operators seat to each of the sliding` sleeves of the propeller es are op erating rods l which are suitably mount/ed for operative action, as shown and illustrated in the drawings. By means of this Itorm of construction the angle of incidence of one or the other of the propellers C can be changed at will so that the flying machine can be directed to the right or left as desired. Or again the angle of incidence of both of the rear propellers C can be changed at the same instant as is desired, to either increase or lessen the speed of the flying machine. As shown in Fig. 3, the propellers C are held in proper working position by means of the yoke brace J and shaft sockets jl which are fastened to' the yoke brace d by means of the'neck "lhis yoke brace and these shaft sockets are made of any suitable material which is light and strong.

rlhe rear rudder or pin D is rigidly fastened to a support all in a vertical position as shown in F ig. l. The support all is braced into position by means of the braces d2. rlhe rudder is covered with any desired make of light but strong fabric while the support Z1 and braces Z2 are made of wood or metal tubing as desired. The function of said rudder D is to keep the flying machine from skidding when making a turn.

The front propeller E is composed of four sections c1, e2, c3 and et, and each section is' composed of two parts e5 and e, built, arrangedand operated the same as are the corresponding parts in each of the lifters or the rear propellers, that is-e5 is braced by ribs c7, pivoted by means of a lug or pivot tonguel e84 to its shaft e2 and operated by means of operating rods @10 and 4en. Each of the rods om are flexibly connected to the inside surface of a section el or e2 orc3 or e4 and rigidly to a sleeve 612 which is part of or rigidly fastened to the shaft c2. Likewise each of the operating rods e is flexibly connected to the inside surface of each of the propeller sections and flexibly connected to a sliding sleeve c13 which is allowed to slide along the shaft e2 when operated upon by means of the fulcrum arms K. The operatii :j rods 02 and c are positioned at each section el or @2 or c2 or et on the inside Lor/aora about one third of the distance in from the outer edge, one rod near one side edge and the second rod near the middle. rlhey run to the shaft e9 at about an angle of 450.

rl`he flexible yoke K, including its members 7a2 and k2, is so positioned that the angle of incidence of the sections el, c2, c, and ct can be changed at will through the medium of the operating rod L, the bell-crank Z1 and the balance rod Z2, which run from the operators seat to the said flexible yoke l. rlhe balance rod Z2 is centrally pivoted at /sl and supported by means of brace supports Z, the flexible yoke member 7a2 connected to a hinge joint., of the flexible yoke l, while the outer joint of the flexible yoke member r'- pivotally hinged to the sliding sleeve cli". rlhe opposite flexible yoke member /u2 is 'flexibly fastened to a sleeve yoke v* which is rigidly fastened to u1 in such as a manner as to positively support the front propeller shaft e.

The front propeller shaft c is divided into two portions by means of the knuckle joint M. rlhe forward portion of the shaft c2 is slidably mounted on a half round table m1 which is rigidly attached to the forward portion al of the platform A. This allows of a right or left hand movement of the front propeller (operating means not shown).

Each respective operating rod on the flying machine has a corresponding operating lever at the operators seat, said levers being positioned within handy reach. fill of lo@ the levers are placed in group and loosely mounted upon a rod N, by any old and well known means and. are retained in operative position byA means of quadrants or other suitable stays or racks nl.' 0n each lever 105 handle is fastened a pinion member of any old` and accepted design which has a biting pinion n2 designed to play along a ratchet toothed rack as rigidly fastened to the retaining quadrant stay or rack nl. This al- 11o lows each of the operating levers to be locked in any desired position.

The motor O transmits force by means of a main shaft 01 to which is suitably geared by means of bevel gear wheels o2, each of the 115 lifter shafts H. Force is transmitted to the two rear propellers C by means of standard chain and sprocket gearing P and p1 fastened to the end of the main shaft 01. Clutches G in the Vicinity of the motor O 120 allow of a make and break arrangement to shut off or start the main shafts 01 (operating means not shown).

The flying machine has the regular standard chassis wheel base.

The operation of the flying machine is as follows: rllhe operator, starting his motor, adjusts the lever controlling the lifter sections so that the lifters operate under a high surface of the propeller, as stated heretofore, i degree of incidence until the flying machine has attained the desired altitude. Then "changing the incidence of the litters to zero so that they become in the nature ot a continuous fiat plane, the operator operates the lever controlling the incidence ofI the front propeller sections so that the sections are drawn to a steep `angle ot incidence, and thus a high forward speed is obtained. It a right or lett turn is desired, the front propeller shaft is turned correspondingly, and the degree ot incidence is changed on the proper rear propeller. If the carrying load 1s too great tor the platform A to sust-ain alone, the propellers are given the proper degree of incidence to assist. It a landing is attempted, the descent is regulated by the degree of incidence of the litters. If the flying machine is in operation and the motor should happen to stop, the litters are brought into a plane and so act as parachutes to assist in breaking the fall. The rear propellers assist the front propellers in driving the flying machine forward according to the degree of incidence allowed, and the speed is regulated by the degree ot the angle ot incidence ot all ot the propellers.

machine is co-related and assists a correspending part, and each one acts as a check on the others.

Having thus described the invention, what I claim as new, is:-`-

In combination with a iying machine, a propeller having adjustable controlled pitch blades, and means to control the pitch ot said blades consistingof an operating rod, a bell-crank lever, a balance rod connected to said bell-crank lever land centrally pivoted on a brace support, and a connecting arm running from said balance rod to a pair of tulcrum arms, said fulcrum arms b'eing connected to said propeller, as described and illustrated.

In testimony whereof I aiiiX my signature in presence of two witnesses.

GEORGE W. LYNN.
