citizen of the United AUGUST 2. HEDBERG, or ivrr ronnf vriissacirosnmrsf 1 a Application filed June 9,

To all-whomitmay concerm v j Be it known that I, AUGUSTVPZ. HEDBERG, av

States, residing at Milford, in the county of Worcester and State of Massachusetts, have invented certain new and, useful Improvements ,in ,Flying Ma-. chines, of which the following is. a speclfication. 1 H

The invention relates to aeroplanes-and mor particularly toflying machines of the paddle wheel type which are provided with construction may be resorted to without de-.

partingfrom the nature of the invention as claimed hereinafter. v h v i Referring to the drawings hereto attached, Fig. 1 represents anaeroplane embodymg the invention in side view and Fig. 2 .is'a front view thereof, parts being broken away.

to in the following descrlptionandindicated in both views of the drawings by like reference characters.- l The body of the machine is designated by the numeral 1 andv may be of'any construe-j tion or outline and as shown is made tapering at'opposite ends and is mounted upon wheels 2, whereby landing may be made w th safety or the machine trundled from one place to another. For proper ,steerlng, the machine is provided with a vertical rudder 3 and a horizontal rudder 4, said rudders being adapted to be adjusted in any well known manner. Side planes 5 give stability to the machine and assist materially in sus taining the same when in flight.

The lifting and propelling mechanism is disposed above the body of the machine and partakes of the nature of an aero-drum which is horizontally disposed and comprises plates 6 and wings 7, the latter being pivoted intermediate of their ends to the plates 6 by means of shafts 8. The wings 7 are curved and are disposed to have end portions over- FLYING MA HINE.

by means of the shaftlO so that adjustment ofthe arm 16 will effect acorresponding adjustment ofthe tracks 14 and 15.

Itis i to be understood that the parts are dupli Corresponding and lik parts are referred cated at each side of the machine. Each sec torarm 16 has itsedge portion'toothed, as in dicated at 17 and in mesh with a' worm'18 on a longitudinal shaft119, the two shafts 19 be'- ing geared to a; transverse shaft 20, so that both longitudinal shafts 19. and sector arm'l6 i when it is,

may be simultaneously operated required to-adjust'the tracks 14 and 15. The

tracks 14 and 15 are ofcam shape'and havev a i a parallel'arrangement'so aszto maintain positive contact with the' wh eels 12'and 13 at every point in the revolution drum. The tracks 14 and 15 serve'to project tion of the drum.

The aero-drum is positively rotated and this IS accomplished by worm gearing, the

same consisting of a' worm gear 21 rotatable with each of the plates 6 and a worm tatable with a vertlcal shaft 23 .journaled to the standards9. Bevel gearing 24 coneach vertical shaft f 1 engine 25- mounted meets the lower end of 23 with the shaft of an upon the deck of the body 1. The worm gear 21 and aero-drumaremounted loosely on the shaft 10, so'as' to rotate freely thereon without interfering with the adjustment of the arm 16 and cam tracks 14 and 15 which as ,stated arcconnected to the shaft 10 which latter in'turn has the arms 16 fastened thereto, whereby the arm 16, shaft 10 and cam tracks 14 and 15 move together.

shaft 10. A suitable coinciding with the the inner end of frame 27. is connected to 7 each of the planes 26 and depends therefrom and isfadapted *tobe adjusted forwardly and rearward'ly at its lower end to change'the angleofltheiplanes 26 as may be required.

The .frame27 comprises a plurality of bars therefrom and passes around which are disposed to form a substantial and light-structure. A cord or rope 28 is attached to the lower end of each of the frames 27 and extends forwardly and 'rearwardly guide pulleys 29 and is wrapped about a transverse shaft 30; Rotation of theshaft' 30 effects a move ment of the cord or rope 28 so as to move the frame =27 and'adjusttlie inclination of the planes 26. Both planes are'simultaneously adjusted because the connections employed infconjunction with one are duplicated with the. other and both cords or ropes 28 are simultaneously operated by the shaft 30.

When themachine is at rest audit is required to rise,-the cam tracks 1et and 15 are adjusted to cause the wings 7 to extend horizontally, so that upon moving downward the air beneath is compressed and as a consequence the machine is lifted. VVhenthe machine is rising, the wings 7 begin to'project horizontally from the upper portion of the aero-drum and to foldafter reaching the lower portion of the aero-drum and while travelling from the lower to the upper position. After the machine has risen to the required elevation, it is propelled by means of the 'aero-drum by adjusting the cam tracks 14L and 15 so as to project the wings vertically upon the forward side of the drum and during their travel from front'to rear, said wings folding upon the rear andtop side offthe drum during such Planes 26 project laterally from the ma-' chine and are adapted to tilt about an axis time. It is also obvious that the cam tracks 14 and 15 may be adjusted so that advantage may be taken of the wings to controlthe descent of the machine when it is required to make a landing. By proper adjustment be projected from the drum and'fold thereagainst at any point in the revolution of the drum, whereby to control the ascent, the

flight and the descent of the machine, as will be readily understood. i

The foregoing description and the draw-' ings have reference to what may be con I sidered the preferred, or approved form of my invention.

It is to be understood that I of the cam tracks 1a and 15, the wings may 1 may make such changes in construction and arrangement and combination of parts, ma

rollers carried by the inner ends ofeach of said wings, cam tracks for saidrollers,sector armsoonnected to said tracks'a'nd gearing for adjusting sa'i'dsector arms andtracks 1 to vary the effective air engaging surfaces of the wings during their revolution.

In testimony whereof I affix my signature I in presence of two witnesses. I v AUGUST P. HEDBEBGQ "Witnesses5 I WALTER I MANN,
