My invent-ion relates to improvements in aerial apparatus or.- flying, machines ofthe aeroplane type. Y

Iii my present improvement' II employ "propellers ofthe helicopter type but so constructed that'they resist'the outwardfftend ency ofth'e air due t0 centrifugal 4Jrce, the object of such construction being to prevent the formation of" an atmospheric cavity or vacuum due to the rotary actionof the pros peller `atthernecessary speed. By virtue of" myimproved construction the tendency lto produce such'ia cavity or vacuum -is overcome and there is practically no Alimit to the Soi-'speed at whichthe propellers may be ro' tated, while with helicopters oftheordinary type, their eiiicient rotary action is limited,

since there is always a .tendency to th'e production o-fan atmospheric cavity or vacuum, whereby the atmospheric'resisting medium is either absent orso rareiiedlas to be .of

littlel value1 In myiniproved l construction I` providethe propellersvwitli" inner: and outer casings 4or housings, through which the blades ipass.

The outer" casings'l or' housings are. also equippedwith atmospheric scoops or buckets, adapted to catch'the atmosphere and d1- rectit inwardly through the" outerhousing thus aiding in maintaining: a proper atmospheric` resistingmedinr for thepropellers under" l-offfthe propeller,

In any event, the axes of'th'e lifting the horizontalipropulsion propellers.

. Having briefly outlined my improved construction, I'will proceed to describe the same 1n detail, reference being'made to the accompanying drawing in which is illustrated an' embodiment thereof' In' this drawing: Figure 1 is a section taken through an airship or flying machine equipped with my improvements. Fig. 2 1s a top' plan view of one of the propellers. Fig; 3 is a similar view showing a slightly modified form ofconstruction. ,a top plan view of the airship which, as illustratedin the drawing, .is of the mono- `plane type.

The same reference characters indicate the same parts in all'the views.

Ijet-the numeral 5 designate a platform upon'which: are mounted 'posts 6, connected by'means ofibraces 7 with' an upper framework 8, forming a support for anv aeroplane 9,'the latter being connected with the framework 8 by means of supports 10. Theaeroplane is provided with openings in which cylindrical casings -12 are located, the latter'beingopen at both extremities and adapted' to coperate with propellers 13 the propellers being coincident'with those ofthe casings 12." Connected with the supports 10, above the aeroplane and'extending overl the propellers in cruciform style is a lskeleton' frame 1 4," through whose central lportion the upper extremity ofthe propeller shaftlpasses. This skeleton structure forms shaft.. Each propeller, which is of the heli- 'copter type, is composed of blades 15 which pass through inner and'outer housings 1G and '1"("respectively.* As show-n in Fig. 1, "the: outer housing. is cylindrical while the walls beingoutwardly ared from their lower edge, thus havinglatendency-to cause move toward the center to neutralize the loutward tendencyl due to centrifugal force. These housings trap the air so to speak and lmaintain an atmospheric medium of sutlicient'densityfor eflicient use, regardless of the speed at which the propellers are operated. In order to further supply the prowhich are mounted 'on shafts 14,' the axes of' a bearingy for the upper extremity of th'e inner housing, is frusto-conical, its inner Patented Aug. 19,1913.t

propellers are at rightangles to those of I Fig. 4 is- 'the air passing through the propeller to y pellers with an atmospheric resisting medium of the required density, I equip the outer housing with atmospheric scoops or buckets 18, which project outwardly from the outer housing and are arranged to catch the atmosphere outsideof the body of the propeller and direct it inwardly through openings 19 in the said housing, as indicated by the arrows in Figs. 2 and 3.

As shown in Fig. 1, the lifting propellers and the horizontal propellers are of precisely the same construction, the latter, however, being mounted upon a horizontal shaft 20, journaled in bearings 21, made fast underneath the platform 5.

In the form of construction shown in Fig. 3, both . housings 16 and 17 are cylindrical and two sets of blades are employed, one set, designated 22, being interposed between the inner and outer housing and Nsecured thereto by means of bolts 23 and 24; while the other set 27 are secured at their inner extremities to a hub 25 through which the shaft passes, their outer extremities being connected with' the inner housing .by bolts 26, the inner blades 27 having their outer extremities interposed between the inner extremities of the blades 22. In this form of construction the inner housing, as well as the outer housing, is equipped with the atmospheric scoops 18, the inner housing being alsoprovided with openings 28, through which the air is directed inwardly against the blades 27.

As shown in thedrawing (see Fig. 1), the apparatus is equipped with an engine 30, having a shaft 31 connected with the.

horizontal propeller shaft 20 by meshing gears 34 and 35; while the vertical propeller shafts 14 are connected with the engine shaft by means of gears 32 and 33, shafts 3,6 and bevel gears 37 and 38. rlhe gears 37 are slidably mounted on their respective shafts and are provided with collars 39 engaged by levers 40 fulcrumed at 41 and connected, as shown at 42, with operatihg rods 43. By operating these levers the gears 37 may be thrown into or out of mesh with their companion gears 32 and 33, as will be readily understood.

Below each propeller 13 and mounted on the post 6 of the frame work, is a coneshaped deflector 44, having a hub 45 through which theshaft 14 passes. These deflectors are Vequipped with slots 46 through which the posts 6 pass and they are adjustable on the latter by means of set bolts 47.

When the apparatus is in use both the horizonal-propulsion propellers and the lifting propellers may all be in motion and in this event the machine will rise in the atmosphere in a direction inclined to the horizontal, the an le of movement depending upon the relatlon between the lifting and horizontalpropulsion forces. Either of these forces may Ibe regulated as may be deromain sired or. wholly discontinued at the will of the operator and as circumstances and conditions may dictate.

Attention iscalled to the fact that Where the'machine is equipped with a number of lifting propellers, the .individual propellers may be rotated in reverse directions. For instance, referring to Fig. 4, the two propellers at the extreme right and left, as well as those at the top and bottom of the sheet, should be rotated `in reverse directions in order to overcome the tendency of the entire machine to rotate, as might result from the constant rotation of thejentirel set of propellers inone direction.
