SAMUEL D. WHEELER, OF CHICAGO, ILLINOIS.

AIRSHII.

Specification of Letters Patent.

Patented Aug. 29, 1911.

Application flied December 8, 1909. Serial No. 532,014.

To all uihom it may concern:

Be it known that I, SAMUEL 1). WHEELER, a citizen of the United States, residing at Chicago, county of Cook, and State of Illinois, have invented-certain new and useful Improvements'in Air-ships, of which the following is a specification.

My invention relates to air-ships and more s ecifically to propelling and steering means t erefor.

The object of my invent-ion is the provision of improved propelling and "steering means for aerial craft which will render the latter applicable to travel at a greater rate of speed than is possible at the present time with air-ships of the present design, and which will make it possible to steer an airship with greater facilit and accuracy.

A further object is t e provision ofimproved propelling, and steering mechanism as mentioned which will beof great effectiveness and which will be comparatively simple of construction.

Other objects .will appear hereinafter.

With these objects in viewmy invention consists in improvements characterized as above mentioned and in certain details of construction and arrangement of parts all as will be hereinafter fully described and particularly pointed out in the appended claims.

My invention will be more readily understood by reference to. the accompanying drawings forming a part of this specification, and in which, 1

Figure 1 is a side elevation of the rear end portion of an air-ship showing the arrange- Fig. 2 is a. central device detached, taken on substantially the line w-w of Fig. 3,-Fig. 3 is a slightlywnlarged longitudinal section taken on substantially the line y-y of Fig. 2; and Figs. 4 and 5 are transverse sections taken on lines 2 -2 and ev -1w of fieferring now to the drawings, 1 represents the frame-work or body of an ordinary airhip, 2 indicating one of the elevatmg gas bags therefor secured as by ropes 3 thereto. Mounted in the frame-work 1 adjacent the rearward end thereof is a' motor 4, directlyconnected to which is the screw pro eller 5 of the of t e' motor 4 in axial alinement with the power shaft thereof, is a cylindrical tube 6 ship. Mounted rearward open at both ends. Said tube is of a diameter slightly greater than that of the circle described by the propeller 5, the rearward extremity thereof enveloping said propeller as illustrated. Provided in said tube are two longitudinally extending vertically (lisposed partitions 7 substantially co-exicnsive in length therewith. Said-partitions divide the interior of said tube into three passages, a central passage 8 and two similar outer passages 9. Having its stem 10 centrally mounted at the rearward extremity of said tube in diametrically opposed projecting bearings 10 arranged upon said rearward extremity of said tube is a vertically disposed rudder blade 11. 12 is the operating cord for said rudder, the same passing around a channel 'pulley 13 provided upon the upper extremity of the stem 10, and extending forwardly therefrom to. and being operatively connected with a hand-wheel 14;.

Mounted in each of the passages 9 upon brackets 15 arranged, upon the partitions 7 asshown, is a blower 16 of suitable design and driven by any suitable means carried in the ship frame-work. Said blowers are adapted to force air forwardly in the passages 9 into contact with the comprising blades of the propeller 5. With such provision, it is evident, that the air forced forwardly against the propeller blades increases the normal atmospheric resistance to said bladesthereby necessarily roportionally increasing the propelling e cctiveness of the same; it being clear, that the greater the atmospheric resistance to the rearward or operative surfaces of said blades the greater will be the propelling effectiveness thereof.

*The air forced forwardly in the'passages 9 will be forced rearwardly by the propeller through the passage 8, as indicated by arrows. Thus air is irected, as seen, to either side of the rudder blade, this increased draft uponthe latter evidently increasing the effectiveness thereof and thereby making it possible to steer the ship with greater facility.

While I have shown what I deem to be the preferable form of my device I do not wish to be limited ous changes made in the details of construction and the arrangement of parts without departing from the spirit of the invention com rehcnded within the scope ofthe ap pen ed claims.

Having-described. my, invention what I thereto as there might be van, 5

\ air currents and claim as new and desire to Patent is I 1. Inaii; air .-ship,.a1propeller and a rudder arranged therein, in combination with a fixed tubular member interposed between secure by- Letters said propeller and said rudder with its axis- 1n ahnement therewith, longitudinally extendin partitions dividing the interior of said tu passages, and means eratinga drafttand directing the same upon said propeller, substantially as' described.

2. 11 an air-ship, a propeller and a rudder arranged therein, in combination with a fixed tubular member interposed between said propeller and said rudder with its axis in ahnement therewith, said tubular mem; her being open at both ends, longitudinally extending partitions-dividing the interior of said tubular memberinto' a plurality of lon gitudinallyextending passages, and air blowers arranged in some ofv said passages adapted to direct currents of air toward said propeller, substantially as described.

.3. In an air-ship, a propeller and a rudder arranged thereln, 1n combination with a fixed tubular member interposed between said propeller and said rudder, longitudinally extending terior of said tu ular member into a plurality of'longitudinally extending passages, only one of said passages communicating with said rudder, and means arranged in the remainder of said passages for generatin said propeller, substantially as described.

ular member into a plurality of lo'n-, gitudinally extending arranged in some of said passages for genone of sald said rudder, each of the other passages adapted to direct artitions diwiding the indirecting the same towar adapted to direct air currents toward said 1 propeller, substantially as described.

ropeller and said rudder with its axis In an a1r-sh1p,a screw propeller and a rudder arranged therein at the rearward end thereof,in combination with a fixed c'ylindrical tubular member interposed between said ropeller and saidrudder with its axis in a inement therewith, the forward end of said tubular member enveloping said pro eller, two vertically disposed longitudi- 1191 y extending partitions dividin the interior of said tubular member into t irce longitudinally extending passages, the central and an air blower arranged in an air current toward said stantially as described.
