Application filed October 2 7, 1908. Serial No. 459,790.

to provide gas inflated reservoirs or balloonarrangements that have buoyancy enough to keep them above the aeromotor and so secured thereto t'hatthe equilibrium of the aeromotor is always mamtalned and it can not turn over. This I do by the invention illustrated in the accompanying drawings in which similar-numerals indicate like parts throughout the several views.

Figure 1 is a side elevation of the aeromotor frame and mechanical parts. Fig. 2 isa plan view of the deck. Fig. 3 is an Fig. 4 is a vertical section lengthwise through the counter-shaft and vertically in alinement thereiwth through all the other parts. Fig. 5 is an enlarged vertical elevation of the arms of the rocking shafts and the links connecting them. Fig, 6 is a rear elevation of the propeller. Fig. 7 is a detail of the cranks and connections. f v i The engine 1 is one of the ordinary powerful typevengines and is located below the lower plane or deck 28, in the hull 29, of the aeromotor; and it imparts motion to the main shaft 46, that is directly below countershaft 16, and that is mounted in bearings, and carries thereon pulleys 1, similar in construction, one located near the one side and the other near the other side of the hall 29. One of the pulleys 4 carries helt 5, that operates pulley (3, on the counter shaft 7 that is mounted in suitable bearings 8. The countershaft 7 -.:1rries a conically sha )ed friction gear 9, that is fitted to engage by .riction with a cone shaped gearlO, which is secured on the propeller shaft 11, said shaft is held in place by bearings 12 and 14 and it is so constructed that with the lever can be thrown into or out of commissiou.- On the outer end of the propeller shaft. 11 is the propeller 15. The propeller 15 has a. plurality of pairs of blades each succeeding pair being one half the length of T the preceding pair and the angle of pitch of each succeeding pair of blades i creases as their length decreases so that. all of the air within the area of a circledescribed by the longest blades is utiliztah Mounted on the lower plane or deck 28 in suitable hearings 3, is the counter-shaft 11", that car-- ries thereon a loose pulley 18, which is provided with a friction gear 17. closes and engages loose pulley 1S and pulley pulley 18. The counter-shaft 16 is also provided on the endr thereof with cranks 20. Fitted on saidcranks 20 are one end of links 21 and 22. The upper end of the links 21 are pivoted to the upper end of the arm of the rocking shafts 24 immediately in front of the counter-shaft 16. The lower ends of the links 22 are pivoted t( the lower arms 23 the counter-shaft .16. one end to thelower arm of one rocking shaft and the other end to the upper arm of the next succeeding rocking shaft as you would move forward from the counter-shaft 16. And as you move to the rear from said shaft 16 the links 25 ,are pivoted one end to the upper arm,23 of. one rocking shaft 24 and the other end to the lower arm 23 of the next succeeding rocking shaft.

Fitted on or integral. with the rocking shafts 24: are the wings 26 and 27, and the wings 26 and 27 are constructed alike, a concavo-couvex form, the convex side uppermost and are provided near the center with a. valve. 2, that is shown dotted in, and that is secured thereto on the concave side and so arranged that when the Wings are raised the valve opens and when they are lowered the valve closes, the purpose being to allow air to pass through them freely in the upward stroke and yet not allow any air to pass through them in the downward stroke, and said wings are so adjusted on said rocking shafts 24, that wings 26 are in a horizontal position when wings 27 are in a vertical position, and he mechanism is so adjusted that wings 26 are descending when wings 27 are ascending and vice versa. The front part of the deck 30 is hinged to the deck 28 so that it may be raised or lowered from the horizontal at its 'front edge. This change of position is'controlled by a threaded and swiveled bar 32. one end of which is fastened to the hinged deck 30, the threads of which bar engage th of the rocking shafts 24: next in the-rear of Links 25 are pivoted,

Belt 19 in- 4 on the main shaft bciieath the loose threads of a vertical standard 31. And suit. I

bar 32 has also provided on the other end thereof a hand-wheel 33. The hull 29 is constructed of a light, yet strong framework and covered with material that is light, yet impervious to water, the intention being to so construct the hull as to offer but slight re sistan'ceto the air when the aeromotor is in motion, at the same time should the aeromotor descend into the water for any purpose, no injury would occur and the aeromotor could rise from the water as well as from the land, the hull being of sufficient depth that the lower plane or deck 28 would not touch the water, although a part of the hull 29 might be submerged therein. A rudder 34is hingedto the front end of the hull 29 and by means of the ropes 35 passing around the rudder standard 36 and as operated by rudder wheel 37, the rudder may be turned to the right or to the left. 011 the lower end of the rudder standard 36 is fitted a wheel fork 43. 'A similar wheel fork is provided at the rear of the hull, but is stas tionary and within those forks are ordinary automobile wheels 44. The upper ends of the wheel forks 43 are fitted within the air chests 45 that are filled with compressed air so that the jar of the aeromotor striking the ground would be cushioned on the air in chests 45. v

Secured to the. deck 28 by flexible guid ropes or stays 38 at a plane parallel to the deck is the upper plane 39. Secured to sai. plane 39 is the cigar shaped gas reservoirs 40 that are held in place by spread tubes 4 which are part of the frame of the plane. The number of these reservoirs may be increased to three or more the drawings herein showingbut one.

An equal number of wings 26 and 27 are provided on each side of the aeromotor.

The description of the parts and the mechanism moving them applies as well to one side as to the other. It is not the intention of the inventor to confine himself to any particular number of wings the intention being to provide apart of the lifting power and also some of the propelling power for the lower plane by these rapidly moving wings 26 and'27.

The propelling power of propeller 15 as applied to the planes 39 and 28, and espe cially to 28 when its front part 30 is raised, is suflicient to overcome gravity when aided by the upward power of the wings 26 and 27.

It is not the intention to use the gas reservoirs 40 for any lifting purpose, except to carry the plane 39, the object being solely to maintain the upper plane 39 at all times above the lower plane or deck 28 by the in- "flated reservoir; 40, and the twoare so stayed and held. together by the flexible stays 38, that the two planes are parallel at all times and the lower deck and moving mechanism lateral by means of the rudder 34 and can not be turned over, but its equilibrium will be maintained while in the air and on the ground by the buoyancy of gas reser- 44, and power being imparted to the counter-shaft 16 by the engine 1, the propeller 15 having been thrown into commlssion by means of the lever 13, the wings 26 and 27 are given rapid motion and this causes the aeromotor to move forward on the wheels. The front part 30 of. the deck being then tilted up by means of the hand-wheel 33,

- being turned for' that direction-the aeromotor then leaves the ground. The downward motion is given the aeromotor by lowering the front part 30 of the deck below the plane of'the deck. Its direction is at all times under the control of the aeronaut, the

vertical by the hinged deck 30.

Having thusdescribed my invention, I desire to secure by Letters Patent andclaim.

In an aeromotor the combination of, two covered planes that are spaced apart and guyed to eachother by flexible stays, cigar shaped inflated reservoirs which are incased within the upper plane, and a power driven propeller having a plurality of pairs of blades each succeeding pair one half the length of the preceding palr and whoseangle of pitch increases asthe length decreases.
