To all whom it may concern:

Be it' known that I, NATHAN ROBERT LAMB,

vcitizen of the Unitedy States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Flying- Machines, of which the following is a speci cation.

The present invention relates to improvements in flying machines and relates particularly to that cla/ss of 'machines having motor driven lifting and propelling fans.

One of the objects ofthe present invention is the construction of .an improved lifting and propelling fan adapted to exert great lifting and propellingA power when driven by a motor. i

Another object of the invention is the construction of an improved aerial vehicle have in a pair of parallel or oppositely arranged li ting' fans and a pair of oppositely arranged propelling fans wherebythe vehicle can by the application of power be propelled and lifted through the air.

With the above and other objects in View the invention relates to certain improvements consisting incertain combinations, arrangements, and constructions clearly illustrated in the accompanying drawings, in which,

Figure 1 is a plan view ofthe completed aerial vehicle, Fig. 2 is a side elevation, partly in longitudinal section, Fig. 3 is a detail plan View of one of the fans, Fig. 4

is a detail side elevation showing the operf ating gearing for the lifting screws, Fig. 5 is a similar view showing the gearin for the propelling screws, Fig. 6 is a vView o a modified form of fan construction, and Fig. 7 is a detail View of an operating clutch.

Referring to the accompanying drawings illustrating the invention 1 denotes a car or frame, which is formed somewhat in the shape of a boat, and is provided with supporting legs 2 and 3, which are each provided with a runner wheel 4.

,As a support for the vertical operating shafts 5 and 6 longitudinally extending rods 7 and 8` are arranged above the bed of the car or frame 1, the forward ends of said bars or supports being bent downward and connected to the forward sides of the frame or car 1. The rear ends of the supports or rods 7 and 8 are bent downwardly at right angles tothe upper portion and connected t'o the rear end of the car or frame 1 at 9: The

rods or supports 7 and 8 are braced on the car or frame 1 by means of braces 10, which connectjwith said rods or supports and the inner sides ofthe car or frame 1. Y

The lower ends of the shafts 5 and 6 are provided' with bevel' gears 11, which are engaged'by ears 12, fixed on horizontally and transverse y extending shafts 13,. which shafts are providedwith gears 14 engaging with gears 15 fixed on motor shafts 16 or,

motors 17. 'The lower ends of the shafts 5 and 6 are supported on the car or frame 1 by' suitable bearin 18. The shafts 5 andG extend vertical y through bearings 19, carfried by the rods 7 and 8, andare provided at their upper ends with lifting fans 20. The

lifting fans 20 are made like each other and comprise an inner ring or wheel 21, which is provided with a series of radiating spokes 22 secured at their inner ends to hubs 23, which are fixed on the shafts 5 and 6. An outer ring 24 is connected to the inner ring or wheel 21 by a series of vanes or blades 25, which are disposed tangentially relative to the curves of the wheel or rin 21 and the ring 24. The outer ends of t e blades or vanes 25 are connected.4 to the outer ring 24 by means of attaching plates 26, which are formed with angular arms 27 riveted to the inner side of the ring 24.- The inner ends of the blades are connected to the inner ring 21 by means of attachments or clips 28. The blades 25 broaden from their inner ends to the outer ends and are formed with flat surfaces. The fiat surfaces of the blades 25 are disposed at angles of substantially forty live degrees to the axis of the shafts 4 and 5, and the narrower inner ends of said blades are arran ed so that a portion 25*l of the inner end o 'each blade, 25 overlaps the adjacent angle less than a right angle to the shafts, Vowlng to the radius of the inner wheel or f'ring 21. The outer ends of the blades 25 are spaced apart' from eachother so that corners 2 5b will project over the outer rings 24 and Is aces 25 will formed between the outer sides of thebladesi@ Itwill bepseen from an examination'ofthedi'awin that the inner ends of theblades' 25am se y'substan'tialljf*`right angles to `the adjacent 1u, in pan, a

portion lof the inner rings, while the. outer ends of'the blades cross `the rings 24 lat angles of about 20 degrees.

toward the fan, thus concentrating the car or frame 1.

power of the fan and increasing the density of the air on one side thereof while decreasing the density of the air on the otherside thereof so that the vehicle will move through the air at the proper speed and with the proper security.

,On the end of the car or frame 1 a shelf 30 is formed', and above this shelf another shelf, or arm, 31 rojects outwardly. Between these two s elves or arms a rudder shaft 32 is journaled, and on this rudder sha-ft 32' a lrudder 33 is mounted. The upper end of the shaft 32 is provided with a cross arm 34, which is connected to ropes' or operatin members 35, which extend forwardly of the rudder, being passed over guides 36 and '37, arranged on the frame or car 1, and connected at their forward ends to cross arm 38, which is connected to a post 39, operated by a handle 40. By turning the -handle 40 the 'flexible connecting members or ropes 35 are moved over the guide pulleys and the rudderis moved .according to the direction in which the handle is turned or operated. The extreme turning ypositions of the rudder are indicated in dotted lines in Fig. 1.

In order to propel the vehicle two oper # ating shafts 40 and 41 are arranged on the The rear ends of these shafts are supported on bearings. formed in the rear end of the support 7 and carry propeller fans 42, which. are. formed like the lifting yfans 20.

The propeller fans are preferably provided with four blades 42, which are connected to inner rings 43 and outerrings 44. Two ofthe blades are Jarranged so that their axes will be disposed substantially parallel to each other,in plan, and the axes of the other blades will'be disposed at right angles thereto. propeller'blades or fans the blades donot overlap as in the arrangement of the lifting fans. The blades 42 are fastened to the inner wheels vby clips or attachments 45 which are located midway of the sides of the blades, thus holding the adjacent end of the blade at right angles to the adjacent In the construction of the Lacasse portion of the inner rings 43. The outer ends of the blades 42L are connected to the outer rings44 by attaching plates 46, which have angular arms 47, connected to the outer rings 44. The at surfaces of the blades .42 are disposed at right angles to the operating shafts 40 and 41, and these blades are formed with taperingy bodies, the smaller or narrower ends constituting the inner ends of the same. Spokes 47 connect the inner wheels or rings 43 to the hubs 48, which are .mounted on the shafts 40 and 41. The shafts 40 and 41 areI driven by means of a motor 49, which is connectedtherewith through the medium of a clutch and gear mechanism. The outer end of the shaft 50 of the motor 49 is journaled on bearings v51 and is provided with gears or sprocket wheels 52, which wheels connect with sprocket or driven chains 53 and"54, which chains extend outwardly to connect with sprocket orgear wheels 55 and 56, supported by bearing brackets 57, and 58. The center wheels 51 are supported on bearing bracket 59. The bearing racket 58 supports a follower gear wheel 59, which engages'with a wheel 60 mounted 'against the wheel 55. The wheel 59 is mounted on the shaft 40, and the wheel 56 is mounted on the shaft 41.

The motor shaft 50 is formed in two sections, one section being provided with a double flanged collar 61 having a clutch cone 62 thereon, which cone is adapted to frictionally engage with a secondl cup-shaped cone 63, having a collar 64 mounted on the portion of the shaft 50 which is directly connected to 'the motor 49.' The collared cone 61 is movable on the outer end of the shaft 50, to which it is keyed, and is operated by means of a Spanner rod 65, which `extends forwardly and is connected with a pivotall supported foot treadle 66. The motor sha 16 is also formed in two parts and these two partsareconnected together by a `frictional clutch similar to the clutch shown in section in Fig. 7 and -describedin connection with the propeller shafts. The clutch 67 of the motor shaft 16 is operated by a forwardly extending Spanner rod 68 which connects with a pivotally supported foottreadle 69. While operating the motors at high speed the lifting and propeller fans can be gradually brought from dead rest to high speed through the medium of the friction clutches, thus preventing an abrupt action of the propeller or lifting fans.

The blades 25 of the fans 2O are braced on lthe shafts 5 and 6 bymeans of wires 70, which are connected to the outer corners of the blades 25 and the collars 71, fixed on the shafts 5 and 6. The blades v42a are braced on the shafts 40 and 41 by means of wires 72 which connect with the outer ends of said blades and with collars 73, fixed on shafts 40 and 41.
