ERGNAIJUCS.

To all whom it may concerne Be it known that I, BARTHOLOMEW CoNNoLLY, a citizen of the United States, residing at Tonopah, in the county of Nyc and State of Neyada, have invented new and useful Improvements in Aerial Machines, of which the following is/a specification.

My invention relatesimprovements in apparatus designed to rise'inlnf.' e the air.

lt consists in the'combination of parts and details of 10 construction which will be more fully explained by reference to theaccompanying drawings, in which- Figure l is aI lan view of my machine. Fig. 2 is a vertical lon i inal section of same. Fig. 3 is an eny I larged view ocontroller shaft, and connecting mechand-'-15 isms. Fig. 4 is another enlarged view of same. Fig. 5 is a partial section on an enlarged scale of one wing,

Yshowing its construction.

The`appara`tus consists of a body or frame-Work of light construction which serves as a basis and support 'l 20 -for the operatingdevices which comprise the structure. Such a frame-work may be made 'of aluminium and of anyrshape designed. It may have the general outline of a flat-bottomed boat, as at A, Which will serve the l "purpose very well. Under this main frame-work,what 5 '.evr may be its character, may be located a false bottorn as at 2, and'bctween this and the bottom -of the A frame-work or car A, are fixed a number of springs of `-any suitable character, such as shown at 3. These l 1. springs serve to relieve the parts of undue concussion when-the machine alights. I l 'Afis'a lever suitably fulcrumed to the car and having a segmental end about which a chain or other connection 'pa'sses. The opposite end of the chain may be attached to the false bottom, asshown at 6, and by the l proper movement of the latter, this false bottom will be raised toward the -bottom of the structure A, and thus crease the tension of the springs, and their ability to ist'the concussion.

theapparatus is ready to start, by disengaging lever the springs will be allowed to expand, and by petus which will assist in raising it in conjunction with jfthe operation lor those parts' which are especially de- -jsigned to raise and maintain it in the air. y L .r' .Shafts 7 extend across the main frame-work at as 5`many points as may be found desirable, and the ends of theseshafts are provided with cranks, as at8, which act l, ,toreciprocate the wings, as I have termed them, which I y Wings guided and movable vertically, serve to raise the apparatus into the air while in motion. Any suitable motor, which is competentfor the work may be em- I ployed, such as a 'light internal combustion engne. iThe wings are mounted on vertically slidable stems 9, and these stems `are provided with cross-heads and guides which maintain them in proper direc tion.

AERIAL MACHINE.

Patented Nov. 12, 1907.'

able guys or braces are also employed to steady the stems, and prevent undue transverse vibrations.

Each crank shaft is provided with friction clutches of any suitable character. Such clutches are here indicated at 10, and each clutch-is actuated bylevers 11) having knuckle joints as at 12; and a means for operating the levers and clutches so that the operator may y control the clutches allowing certain clutchestislip,

while others maintain their full driving power, sothatif- 65 be restored to an equilibrium by varying the speedfof the machine is inclined to one side orthe other, it may movement of the wings upon the two sides of the appa ratus; and it will be understood that by in the'samen manner varying the speed of the Wings at eitherfront j or rear, the apparatus may be inclined with its head upwardly or downwardly so that the action of the pro pellers, driving it forward, will aid in raisingforlde' pressing the machine. Any suitable number of, wings (not less than four) may be employed, dependent upon; f the'size and weight of the apparatus, and the Wings-donf.,-`` responding with the heavier portion of the machineh'l, may preferably be placed nearer together thanthos at the 'ends Where the apparatus is lighter. The shafts are turnable in suitable bearings at the'ends, and preferably also at each side of the friction clutches. jf

These clutches, as before described, regulate thevspeedv of reciprocation of the wings, and are an important ad-j junct in preventing the tilting or turning over ff-11h`y machine. l

I The lever of each friction clutch consists of two ll-lla connected by means of the joint 12,asppre--l 'I viously stated. This joint is of such a character, like a knuckle or elbow joint, that it may bend ingonedif .I

rec-tion by a movement oi the lever, and rcrnainlrigid in the opposite direction, so that it will serve to either of these clutch members.

Power may be transmitted from the motor by a series will be suchthat all the transverse shafts will be turned in the same direction. n

The friction clutch levers of the shafts 7 are connected by rods 18 having slotted ends through holes in which y .A y

pins pass as at 19 to connect the two, and by making a4 l' series of holes, the pins may be changed so as to vary l v105 the position of the rods 18, and lengthen or shortenthe distance between the clutchpperating levers;` this representing a form by which such adjustment may be hold the lever rigid, and provide sulicient power to f force the clutch members strongly together, ,or it 'mayflt' v` i yield sufficiently to allow a certain amount of slippage t 95. of connev ting shafts i6, and beveled gears at the ends" of said shafts as at 17, or by belts and pulleysor other-1l suitable mechanism. The arrangement oi 'these gears 20, which teeth are engaged with pinions as at 2l upon a shaft 22, which 1 term the controller-shaft. This shaft extends fore and aft of the apparatus, and the pinions 21 engage the rack bars which control the levers and clutches o each of the transverse shafts 7, and by means of a wheel 23, or other suitable attachment, control of all the clutches is in the hands of the single operator. The pivot points 12 of the two part levers 11--11e4 may be considered as fixed fulcrums, and the overlapping extensions of the parts 11 will press .against the inner sides of the parts l1, so that if both parts 11 are drawn towards each other, they will act through the parts 11 to force the clutches into suflicient frictional contact to drive the connected parts. These levers are thus held to produce the necessary pressure by being pinned to the bar 18 at points .19 of lFig. 3. New when by turning the pinion 21 which engages the rack 20 on the bar 18, this bar is moved in either direction, it will act to pull one of the parts 11, and by reason of the extension overlapping the joint 12, it will press the part 1l which' is a continuation and lock the clutch more firmly. The part 11a at the opposite end will turn loosely oir its pivot and will thus relax the pressure on the part 11, because the overlapping extension will be moved away from the joint l2, and the clutch engagement will be relaxed enough to allow some slippage and a slowing up of the driven parts, by reason of the friction which will be sucient to slip the clutch a little'. The levers are long enough and have suieient elasticity to allow the above movements which need not be very great. lt will thus be seen that by turning this controller-shaft in one direction, the interlocking of the friction clutches upon one side may be maintained, while those upon the other side Will be loosened or partially released, thus allowing a slippage which will decrease the sustaining power of the wings upon that side by lessening the number o reciprocations; and the comparative effectiveness o the wings uponthe other side will be increased; thus the machine will be maintained -in equilibrium if it shows any tendency to list to one side. There is a certain amount of play in the knuckle joints which will provide lor the variation or' the clutch engagements above described.

The controlling shaft is properly supported by a series of boxes or bearings as at 24, which are disposed at su'icient points in its length, and are properly supported upon the frame-work.. These boxes allow the controller shaft to turn, and also permit it t0 move longitudinally so as to maintain the pinions 21 in engagement with the racks 20.4 This is necessary because the movement of the connecting bar 18, and the parts 11L of the clutch levers changes their relative position so that from forming substantially the sides of a rectangle, these levers and connecting bar form a. rhombus` shaped figure, and there is a certain movement in the line of the controller-shaft caused by this change of position which requires` the compensation above described.

In order to maintain the pinions in engagement with the racks7 I have shown a yoke or inclosing device 25 which tits loosely around the controller shaft, and close up to the gear-wheel upon each side, and thence passes under the connecting bars 18. This insures the movement of the connecting bars and the shaft 22 in unison, and maintains the -pinions and racks in gear. The

controller shaft is slidable with relation to the pinions, and may either have a feather or be polygonal in section so that the pinions will be turned by the rotation of the shaft whatever the sliding movement of the latter may be. l

The wings, as I have termed them, are in the form of cones, or umbrella-shaped. The crown piece 26 of each cone is xed to the top of its stem 9, and ribs 27 radiate from the periphery of each crown piece, which may be screwed upon the 4upper end of the stem7 threads being cut for that purpose. periphery of the wing, two circular bands overlap each other, as at 28, and may be riveted or otherwise secured together, the ribs being clamped between the two bands, and thus held firmly together and in place. From the edges of the wing-bands7 ribs 29 converge to the stem, and are interlocked with a collar 30. which is fixed upon the stein as shown; thus the ribs and the braces form a sufficiently stiff frame-work to prevent distortion of the wings, which thus retain their permanent conical shape. l

The covering of the wings consists of two parts. From the crown-piece to about the middlle, or at the position of the uppermost first circular band 28, the covering may be made of strong silk, or other equivalent substance, which is formed to fit the outline of the frame. This covering is held in place by a secondary rib which overlaps and is clamped to the inner rib, the covering being locked between the two ribs, and so -held in place. This second exterior rib extends only to the periphery of the first circular band 28. These circular bands thus serve to clamp the ribs and the edge of the covering and make a unitary structure. From the upper band to the lower band a single main rib extends, and the covering of this portion of the wing is in the form of doors or shutters 31, which are hinged to the ribs as shown at 32, so that these shutters may open inwardly when the wing is raised, thus allowing the air to freely pass through this portion of the wing which contains the largest area. When the wing is again drawn downwardly the shutters will be closed so as .to form a large wing space with corresponding pressure upon the air, and the effect ol which will be to raise the apparatus at each downward impulse of the wings, while the upward movement opens the shutters, and allows the air to pass freely through this portion of the wings. These shutters may be made of light sheet aluminium,-and they are guided and prevented from opening too far inwardly by a circular wire brace 33 which extends around the periphery of the wing, and is held in place by means of I- bolts 34 which project inwardly from the ribs by which they are supported in any suitable manner. These I-bolts or braces are of such a length as to allow the doors to swing inwardly to form an angle of approximately 45 degrees so as to admit a free inrush of the air; but maintaining the doors in such a position that they will be readily and automatically closed by the opposite movement of the air during the downstroke of the wing.

The doors are made suficiently larger than the spaces between the ribs so that they will close fairly against the casing thus formed, and not be forced through the spaces during the down-stroke. These doors increase the resisting power of the wing on this At the edge or feathers at the tip of a birds wing.

In very large wings,` two sets of rib braces 29 may be necessary, the inner set being disposed intermediate between the ends of the ribs and the crown-piece, as at 29a and approximately near the upper circular bands. These braces are in every wayY similar to the set previously described, and are secured to central cones 30Et which are fixed upon the stem 9. The circular bands 28 to which the ribs are secured, are preferably made with grooves or channels between which the ribs pass, and they .may be secured by rivets or bolts passing through the ribs upon each side of these channels, as.-

shown at 36. The stems 9 have cross-heads 37 slidable in vertically xed guides 3S. These guides may be made of aluminium formed into I-shaped bars which are fixed upright'upon the frame-work and parallel with the stems 9. The flanges of'these guides may be cut away on the side toward the wing, leaving only a sufficient amount to form the guide for the cross-head.

0n the inside of these flanges a seat is fixed in whichV the cross-head works. Fromthe upper ends of the 'guides a light tube 39 extends parallel. with the stem 9, and each of these tubes extends up through the covering of the win". The upper part of the stem has guides 40 through which the tubel passes, and these guides are freely slidable upon 'the tubes when the stems and wings are reciprocated. Braces 41 extend from the flanges of the guides to the frame-work, andthus steady the lower end of this portion of the structure. These guide rods 39 may be provided with elbows as at 42 above the upper ends of the wings, and these may be connected by light rods or pipes 43, which may extend across and also lengthwise of -the apparatus. Thus any four'of these top braces being connected, forma rectangle, and to further steady the apparatus, guys 44 are provided, these guys having turn-buckles, as at 45, by which any degree of tension may be produced.

The rudder 46 may be made by riveting a light sheet of aluminium to an inclosing and suf'ciently stiff frame to hold the sheet in place. The rudder may be turned in any suitable manner. As here shown a pinion 47 is fixed upon the turning axis of the rudder, and a pinion 48 engaging with 47 is mounted upon a shaft 49, which is provided with a wheel 50 suitably placed for convenient use by the operator. If desired a second rudder may be placed at the front of the machine, and the two may be operated in unison by means similar to that just described. A

The openings in the covering of the wings through which the tubular rods 39 pass may be inclosed and protected by metal bands riveted to the covering material, or to the ribs, and between which bands the covering material may be clamped.

Power to propel the apparatus after it has been raised from the ground, may be provided by screw propellers 51; these propellers being mounted upon shafts 52, and by means of bevel gears as at 53, the shafts are driven from a main shaft 54, This shaft has a friction clutch 55 within its length, operated by any suitable lever and connection between it and the position of the operator so that by disengaging this clutch, it is possible to concentrateall the power of the motor upon the operation of the wings until the apparatus has been lifted. above the ground to such a height as desired;

the clutch of the propellers may be let in, and the latter commence their movement to drive the apparatus ahead.

AThe various clutches are important in the control of the apparatus: first, by disconnecting the propellers to allow the wings to operate and raise the apparatus to the desired elevation; then by engaging the clutch of the propellers, the latter may be set in motion; and if desired the clutches controlling the wing reciprocations may be allowed to slip sufficiently to reduce the elevating power, and just maintain the apparatus at a normal elevation, while the propellers act to drive. it forward. Or, if desired, the wings may still be continued in full operation while the propellers are operated, so that the apparatus will be driven bothforward and upward; and in a similar manner by reducing .the reciprocations of the wings, the supporting power may be so reduced that the apparatus will gradually sink and may be at the same time propelled forwardly so that a favorable position for alighting may be reached before the apparatus actually reaches the ground.
