FLYING MACHINE.

Application mea March 11, ieee. serial iro. 93,824..

The present invention has for its object to produce a simple and novel propeller and controlling means therefor, which will pers mit the propeller to exert a pulling force along any radius of a large arc.

My improved propeller may be used either as the sole sustaining and propelling means for an aerial vehicle, or it may be employed to assist other means for raising or lowering or moving a vehicle forwards or backwards.

A further object of the present invention is to produce a simple and novel propeller and controlling means therefor which will serve to lift an aerial vehicle, move it backward and forward, and serve effectively to check the descent of the vehicle in the event `of failure of power.

`my invention is characterized will hereinafter be pointed out with particularity in the claim; but, for a full understanding of my invention and of its objects andadvantages, reference may be had to the following detailed description taken in connection with the accompanying drawings, wherein:

Figure 1 is a side elevation of a heavier than air vehicle, equipped with a lifting and propelling device arranged in accordance with my invention; Fig. 2 is a front elevation of the vehicle; and Fig. 3 is a section, on an enlarged scale, taken on line 3-3 of Fig. 2. Y

In the drawings I have illustratedl my invention as applied to an aerial vehicle that is heavier than air and, for the sake of brevity, I shall confine the detailed description to this particular embodiment, lsince the principles of operation applicable to other uses will be evident from an explanation of this particular use.

Referring to the drawings, l represents a vehicle body or fuselage, underneath the front of which may be supporting wheels 2, while the rear end may be supported on a trailing arm or stem 3. A frame 4 rigidly Connected to the fuselage, rises therefrom. My improved propeller is mounted in the upper end of the frame. The upper portion of the frame comprises two separated side members between the upper ends of which extends the propeller shaft 5. The propeller shaft is shown as having four radial arms or spokes 6 rigidly attached thereto near each end. Between the outer ends lof each pair of arms `or spokes extends a rotatable shaft 7 ment shown, each of the shafts 7 has a sprocket wheel 8 secured thereto. An end less sprocket chain 9 passes around all of the sprocket wheels S, so that when one of these shafts rotates aboutits axis, the remainder are similarly rotated. Rotation of oneof the shafts 7 about its axis may conveniently be effected by placing on the shaft 5 a sprocket wheel 10 that is loose on the shaft, so that it may be held stationary while the shaft rotates, and providing the shaft 7 with a` sprocket wheel 11, `around which and the sprocket wheel 10, a chain 12 passes. lVhen the sprocket wheel 10 is held stationary, and the shaft 5 is rotated, the vanes will be revolved bodily about the shaft 5 and'will "also revolve about their own axes of rotation.

The vanes must not only revolve about their own axes, but each must yrotate through an angle of only 180 degrees about its own axis while it is traveling bodily through an angle of 360 degrees. To this end the sprocket wheel 11 is provided with twice as `many teeth as the sprocket wheel l0, whereby the sprocket wheel 11 will make only half a revolution about its own axis while it is swinging through an angle of 360 degrees about the main axis of the propeller.

In order to permit the vanes to be made light and at the same time to be rigid, each may be provided` with trusses 13, there being two of such trusses at each end, lying on opposite sides of the vane.

The propeller shaft may bex driven in any suitable way as, for example, by a motor 14 arranged within the fuselage; the shaft 15 of the motor driving a countershaft through a sprocket chain drive 17, and the shafts i 16 and 5 being connected 'by a sprocket chain drive 18.

i/Vhen the propeller is rotated, its effect on the vehicle depends entirely upon the initial
