To all whom it mam.-

'- Be it known that I',1;EwALi) E. semantics,

a citizenof the-United'States'; and. aresident of the city of Chicago,the county oflOook new and'u'se'ful Improvements in Dirigible Flying-Machines; and 'I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying" drawings,- and to the letters of reference marked This lnvention relates to improvements dirigible flyin machines and particularly to that class in w 'ch gas bags are not re uired,

but which receive am initialyelocity. af rising om the ground. Y

It is an important-object of invention to provide a machine in vwhich bothv-- aeroplanes and adequate power 'are'utilized in ifting and propelling "the machine and its load and in which when raised to the desired height the aeroplanes alone are adapted to support thewelght of the machine-when travelmg approximately horizontally, the power directly to propulsion.

and light weight having few-parts, and those easily assembled, and which can becheaply built and maintained.

The invention consists in the matters hereinafter, described and-more fully pointed out and defined in the ap ended claims.

- In the drawings igure 1 is a sideelevation of a device; embodying my invention. Fig. 2 is a view in side elevation, shtFViIlg I ig. 3

As shown in the drawi s: A represents a 1ts middle" toward its pointed ends. Said body may be of any suitable material to afo the groun ford reat strength with light weight. En-

On the-Q inner endof each shaft is providedl'a sprocket wheel Le, which is driven from 'a sprocket wheele, on the motor shaft, by means of a sprocketchain e J ournale on each end of balancefwheel for the motor. Said gear a is provided with a hub e Qn the outer end of against the end of the hub e and-firmly 'se cures the same from longitudinal movement; body or car of considerab e length, as'co m-l pared with its width, and which tapers from- Journaled on each'sectional shaft C-Cf O- is a gear 0 adapted-to intermesh with a gear e on the motor; shaft, in said-gear casing b-,,- nd-which serves as the are aeroplanes G, G Gian d G which are free torotate but are firmly held from movement longitudinally of the shaft. For this ur-,

pose the hubs'of said aeroplanes G, G an abut against the bearings 'on said standards and are firmly held said position bym'eans of collars g, g and g and, the aeroplane G is secured from longitudinal movement by;

means of collars g and g all of which are provided with set screws to firmly hold the same in adjusted position. Said aeroplanes, as shown, icoinprise a hub h, to which are see cured in any suitable manner radial blades h, at right angles to each other. Rigidly bracing said blades are concentric rings or hands h -h which are secured to the side thereof in any preferred manner to form a rigid construction and, as shown, one is positioned near the irub and the otheris of greater diameter and fastened a corresponding distance from the outer ends of said blades. Securely fastened to said ring h and positioned centrally between said blades h are shorter blades h which extend to the outer circumference coincident with the ends of said blades -h, and are-securely fastened attheirsides to the ring or band h A plurality of short outer blades h are positioned between the blades h and h, and are secured at one end to the rings h and their outer ends extend the the same radial distance from the hub as the blades h and h. 4 The outer ends of all of said'blades hh and h? are rigidly braced and held in unvarying relation by means of wires or cords h, which may be of any' desired number and extend around the periphery of said aeroplane.- Any suitable steering mechanism may be provided but,"as shown, rudders II are pivoted to said standards B and B and are each provided with two. tillersii, adapted to be operated .varied.

simultaneously by tiller ropes i, which extend along each side of thecar and through suitable eyes i 7? and at their ends are se-= cured to the corresponding tillers of the rudders.

The operation is as follows: When startin and while the machine is'obtaining its initia velocity, said device travels on the ground on the wheels a/ a. As the velocity increases the aeroplanes gradually lift the machine from theground and the rate of ascension depends upon velocity andthe inclination of said" aeroplanes. The height from the ground at which said maclnne travels in a horizontal position-depends upon the acquired velocity, as a certain speed is necessary before the aeroplanes are self supporting. As long as the machine-travels at the required-speed it continues to travel in this horizontal position. It is now obvious that if the velocity is decreased the machine gradually descends and that at any point in the descent we "may again cause the machine to travel in a horizontal position by.

increasing the velocity sufficiently or may ascend by increasing the velocity above the speed required for soaring. If however, it is desired to ascend without changing the power necessary for the aeroplanes to sustain the machine in a horizontal plane, it

.may be accom lished by shifting the center of gravity or t e ballast to the rear end of the car. At any point in the ascent the machine may be made to again assume a horizontal position by shifting the center of gravity or ballast to normal. The direction of travel is readily controlled by actuating the tillers which simultaneously shifts both rudders to act in either direction.

Easy access 1:; had to the motors by means .ofthe ladders at each end of the car for starting and stopping the same or if preferred the motors may be controlled by mechanism operated from the car. i

If preferredthe standards may be adjustable and providedwith mechanism for si-. multaneously adjusting the same thereby varying the angle of inclination and consequently the rate of ascent and descent.

By my form of aeroplanes it will be seen that the greatest'possible sustainin effects are provided owing to the relatively great length and narrow width and that the resultant area of'all the bladesis the greatest possible to obtain in such a compact form and with light weight.

Difierent forms of rudders maybe used or only one may be used and various forms of aeroplanes may be provided. and different means may be emp oyed for transmitting power from the motors to the propellers and various other details may varied without departing from the principles of my invention, and I therefore do notdesire to'limit myself as to details as obviouslv they may be .I claim as my invention:
