ERI L MACHINE.

Specification of Letters Patent.

Patented Jan. 4, 1910.

Application filed- December 8, 1908. Serial No. 466,467.

To all whom it may concern:

Be it known that I, XVILLIAM E. GoBLE', citizen of the United States, residing at Dinuba, in the county of Tulare' and btate of California, have invented new and useful Improvements in Aerial Machines, of which the following is a specification.

My invention relates to improvements in aerial machines, and especially of that class in which propellers are depended upon to lift and sustain as well as propel the ma-- chine.

It consists in the combination of parts, and in details of construction which will be more fully explained by reference to the accompanying drawings, in which- Figure 1 is aside elevationr Fig. 2 is an end elevation. Fi 3 is an enlarged View showing a means for adjusting the propel-- lers. Fig. 4- is a plan of the inner ends of propeller arms and connections. .Fig; 5 is a section of the steeringmechanism. Fig. 6' is a detail of the propeller arm supporting ring. Fig. 7 is a front elevation of the steering-frame.

It is the object of my invention to provide an apparatus in which propellers turning in a horizontal plane, act to'lift the machine, and one or more propellers are depended upon' to propel and steer the machine; the horizontally revoluble ropellers being so adjustable that in case ov accident,

or for other reason, they may be incidentally converted into parachutes to prevent a too suddendescent of the apparatus.

A is a body or frame-work within which P-r'eferably, the shafts 7 form rigid backfbonesiforsthe propeller blades, and these may be crossed by suitable transverse bars 9 upon which'm-a be stretched a fabric which w ll form'a' resisting surface to act upon or il b'fea 99. by the air as required The The propeller inner ends of the arms 7 are here shown with globular heads '10. The hubs 6 have the periphery slotted vertically, andth-rough these slots the arms 7 extend radially ontward.

11 is a ring having formed in'it vertical slots 12 within which the arms 7 liewith the in unison with: the shaft. The outermost sleeve 14' is. in like manner capable of vertical movement without turningupon the innerniostf sleeve. To the innermost of these sleeves cords 15 are connected; These cords. extend outwardly and have their outer ends secured to the propeller blades below the axes 7 of the propellers. Other cords 16 have their inner ends connected with the sleeves 1-1, and their outcrends to the pro' peller blades above the axes 7. These. cords are so disposed as to maintain the propellers at the best angle to exert the desired power 1 to lift the apparatus when the propellers are revolved- The sleeves are slid'a-ble'with rel-ation to each other, and the an 1c of the propeller blades may thus be adjusted at will.

These sleeves are also slidable bodily upon the shaft, and by moving them up or down, the radial angle of'the (propellersmay be changed so that the bla es may either diverge upwardly from their central attachment to the hubs, or thev may be caused" to diverge downwardly, like the ribsof an unobrella or parachute.

The slots 12 in the-ring 11 allow of the vertical movements of the ribs 7, and the knobs or globular inner ends 10 retain the ribs within the hub.

In case the apparatus is descending, and

it is desired to check its descent, the propeller blades are drawn downward as shown in full lines in Fig. 3, and at the same time. the

blades are turned by the action of the cords 15 and 16 so that they stand substantially flat, and approximately close in spaces tween-theblades. In this position and condition, each propeller forms a parachute,

lid

acting upon the air in such a manner that the descent of the machine will be controlled and greatly checked.

' The vertical-movements of the sleeves 13 and 14 may be effected by connections of any suitable character, extending into the car, and within reach of an operator.

17 is a driving propeller mounted upon a shaft 18 which is suitably journaled at the end of the car. If a plurality of such propellers are employed, they may be journaled at oppositeends of the car. The propeller.

right or left. In conjunction with this is another guide 24 slidable in guides at right angles with the first named slide, and by means of these two the angle of the shaft may be changed up, down, right, or left, or to any intervening point between. This propeller thus serves as a rudder, and in addition to its action in providing a forward propeller, it also serves to steer the machine,

in any desired direction. Suitable mechanism may .be disposed within reach of an operator, so that'the control of the driving propellcr', or the lifting propellers may be within easy reach. The vertical propeller shafts are so mounted that'they may be inclined from a strictly vertical position, and when so inclined toward the front, the propellers will act to assist in'propulsion as well as-in raising the apparatus.

At 25 I have shown a lever, connecting through the link 26 with the vertical propeller shafts 3. These shafts being mounted on hinged bearings as at 27, it Wlll be\seen that when the lever is o erated, the propeller shaft may be thrown orw ard into any .desired angle. 1

Having thus described my invention, what Iclaim and desire to secure by Letters Patent is 1. In an apparatus of the character described, a body and motor, vertically journaled shafts, means for transmitting motion to revolve said shafts, hubs carried upon the upper shaft ends, propellers flexibly connected with said hubs, and means by which the propeller -blades may be raised or depressed with relation to the hubs.

2. In an apparatus of. the character described, a body and motor, vertically journaled shafts, means for transmitting motion to revolve said shafts, hubs fixed to the upper ends of said shafts, propeller blades radiating from said hubs and flexibly connected therewith, and means by which said blades may be raised and lowered in-a vertical plane about their hub ends.

3. In an apparatus of the characterde scribed, a body and motor, vertically journaled shafts, means for transmitting motion to revolve said shafts, hubs fixed to the upper ends of said shafts, radially slotted rings carried by the hubs, propellers having axial ribs extending through the slots and capable of vertical and revoluble movement in the slots, sa'id ribs having knobs at the inner and the propeller blades whereby saidblades may be raised or depressed in a vertical plane with relation to the hubs.

5. In an apparatus of the character described, vertically journaled revoluble shafts, hubs at the upper ends of the shafts, pro- .pellers radiating therefrom, said propellers having axial ribs flexibly and turnably connected with the hubs, slidable sl-evesmounted upon the shafts, connections between said sleeves and 'the propeller blades whereby the anglesof said blades may be changed with respect to the direction of rotation and also with respect to the axes offi the shafts, and means for propelling and steering the apparatus.

6. In an apparatus of the character de scribed, revoluble lifting and .supporting v propellers, adriving propeller, a shaft upon which said propeller is mounted, a'sleeve, and means to revolve said sleeve, a universal joint mechanism carried within said sleeve, and' through which joint the pro- 'peller shaft passes, and guides slidable at right angles with each other with which the inner end of the shaft is connected whereby the'angle of said shaft may be changed to steer the apparatus.

\ In testimony whereof Ihave hereunto set my hand in presence of two subscribing witnesses.
