FLYING-MACHINE. I

Specification of Iietters latent.

To all whom it may concern:

Be it known that I, DAVID SMITH, a-oitizen of the United States, residing at Doug-v las, in the county of Converse and State of lVyoming, have invented a new and useful {lying- Vachine, of which the following is,

a specification.

This invention relates to flying machines ofthe heavier than air type, one of its'objects being to provide a machine of this character having, in addition to sustaining planes, angularly ad ustable controlling planes for regulating the upand down movement bf the machine while in flight.

A further object is to provide elevating nation and arrangement of parts and in the{ details of construction hereinafter described I and fclaimed, it being understood that changes in the preciseemb'odiment ofthel invention hereindisclosed, can be made within the scope of what is claimed, without depart- I I the axis of shaft 6, the roller9 on each crank ing from the spirit of the invention.

In the accompany ng drawings the pre-' .ferred form of the invention has been shown.

' In said drawings :Figure 1 is plan view of the machine. Fig; 2 is a side elevation. Fig. 3 isa side elevation of one of the controlling cams used in 'connectlon with theelevating wheels, the blades being shown in section in two positions and other posi tions of the blades being indicatedby dotted lines. Fig. i is affront elevation ofthe parts shown in Fig. 3. Fig. 5 is a viewpartly in section and partly in. elevation of the-end] portion of the shaft of the elevating wheels.

Fig. (Sis a perspective view of thefparts shown in Fig. i. Fig. 7 is a perspective View of the controlling planes. Fig.6 is a perspective view of the rudder and "its'operating mechanism. 7

Referring to the figures by characters of reference 1 designates the main or topframe of the machine, the same being provided with forwardlyand rearwardly projecting extensions 2 constituting sustalnlng planes. I

The space within the. framel is open and arranged below the frame 1 and the planes -Patented Oct, 20, 1914. Application filed April 11, 1913. Serial No. 760,512.- 1'

manner, asby means of standards 4-. #This lower diamond-shaped framesupports most of the mechanism used'in the propulsion. of

the machine.

I Brackets 5extend downwardly-Efrom'the, 7 sides of the frame 1 andjournaled thereiny is a shaft 6 extending transversely, of the line offiight. This shaft can alsobe jo ur naled in additional brackets 7 extending ups f wardly from the sides of the lower frame Secured to eachbracket 5 as by means of arms 5 is'a fixed cam 8. Thisca'm isprovided, in front of the shaft 6, with an e'ccentric portion 8 merging into atop depression 8?, and located back of this "depression is a concentricportion 8 extending through about and then merging into the lower part of eccentric portion 8*.

Cam ,8is en gaged by rollers 9 located atthe free ends of crank armslO, each crank:armbeing formed on or secured toone endof ashaft I1. Two of these shafts are preferably pro vided the sameibeing parallel withshaft 6 and being journaled in oppositelyextending radial arm 11 which rotate" with the shaft 7 6. Each shaft 11 has a blade 12 fixedly conn'e'cted thereto. Duringv the rotation of shaft 6 and, consequently, of the blades 12 about arm 10 will travel successively alongthe eccentric portion 8 thedepression8 and the concentric portion 8 of the adjacent ,cam.

Consequently during the upwardfmovement of eachshaft 11 its-roller;9rwill.drag along the eccentric portion 8, as shown bydotted lines at A in Fig. 3, thus to tiltthe blades 12 asv shown at A, The roller 9*gradu'ally moves off the eccentric {portion '8? and into the depression 8". A deflecting plate s eX- tion 8a p yitwarts-a6.

fiected downwardly into thedepression as ice shown at B, thusbringing the blades12 to a substantially horizontal position as shown at B. As the shaft .6 continues-to rotate in the stationary cam '8, the depending roller '9 will travel downwardly inthe depression 8" until it strikes the rear endportion ofthe lieu depression as shown at C whereupon the blades 12 will be tilted, as shown at C. Roller 9 will then be caused to drag along the concentric portion 8 of the cam, the blades 12, consequently, being caused to flap over suddenly as the roller 9 passes out of the depression 8 this flapping action, supplementing the downward bodily movement of the blades 12, producing a very quick downward displacement of the air and, consequently, accelerating the liftingaction exerted by the blades. As the rollercont-inues to travel, along the concentric portion: 8 it will maintain the blades 12 practically radial to the shaft 6 until after roller 9 passes of the lower end of the concentric portion, as shown at D, at whichtime blade 12 will be'free to hang vertically until it assumesthe position indicated at E whereupon the operation hereinbefore described will be'repeated. Obviously, therefore, the

blades will operate to displace air clownwardly and will therefore exert a liftingv As one of these action upon the machine. elevating wheels 1s arranged at each end portlon of the shaft 6, and as both wheels rotate in unison, it will be seen that .the displacement of air at the two sides of the 1na-- chine and the lateral balance of the machine will be maintained at all times during the operation of the shaft. 7

As shown in Fig. shaft 6 may be provided at each end with a ball 13 adapted to bear within a socket'l i. Thus friction is reduced to the minimum,

Supported by the lower frame 3 is a motor 15 and motion may be transmitted therefrom through a chain 16 to sprocket 17 r A bevel gear 18 is se- 1 cured to said shaft 6 and meshes, with a. smaller gear 19 which, in turn, is secured secured to shaft 6.

to the rear .end of a forwardly extending shaft 20, the front end of this shaft being provided with a propeller 2'1.-

Extending downwardly'from the sides of the frame 1 are brackets 22 and journaled in these brackets 'are transverse shafts 23' each of which carries an elongated controlling plane 2%. Each plane has an arm 25 extending downwardly therefrom and these arms are connected by a rod 24. A controlling cord 26 extends from one of the arms 25 and is extended over a suitably disposed guide sheave 27 to afoot lever 28.v Substantially horizontal arms 25 may be extended from the planes 24 and springs 29- can be connected to these arms so as tohold the planes normally horizontally. By depressing foot lever 28, cords 26" can be caused to pull on the arms 25 and thus tilt the planes :Copies of this patent mayibeobtained for 24 out of their normal positions, thereby placing the springs 29 under tension or co1npression so that, when foot lever 28 is released, the springs will return the planes to their initial positions.

For the purpose of steering the machine laterally, a vertical rudder 30 is supported chine has reached a desired elevation and even while the machine is moving upwardly, the shaft 6 can be caused to rotatethe blades 12' and as these blades feather it will be seen that they exert a lifting action, thus assisting in the upward movement of the machine and in maintaining it at a desired elevation.

What is claimed is A flying machine including sustaining planes arranged one in front of the other and spaced throughout the width of the machine, parallel controlling planes below the space between the: sustaining planes and extending transversely of the machine, means for tilting the said controlling planes in unison about axes extending transversely of the machine, a transverse shaft j ournaled below the space between the controlling planes, a blade revoluble with said shaft and also revoluble about its individual axis, said axisbeing parallel with the shaft, a stationary cam, a crank arm movable with theblade and around the cam, and means cooperating. with the cam for engaging the crank arm to swing the blade downwardlyv between the controlling planes.

In testimony that I claim the foregoing as my own, I have hereto ailixed my signature in the presence of two witnesses.
