FLYING-MACHINE.

Specification of Letters Patent.

Application filed December 12, 1910. Serial No. 596,760.

To all whom zt may concern:

Be it known that I, GUsrAvn A. XVENDT, a citizen of the United States, residing at Tacoma, in the county of Pierce and State of Washington, have invented a new and useful Improvement in Flying-Machines, of which the following is a specification.

My invention relates to flying machines and has special reference to the means for raising the machine off the ground and for maintaining it at the desired elevation.

The class of flying machines to which this invention relates is that in which the machine is raised by the reaction on the air of moving surfaces mounted on the machine. The mechanism is also applicable to pro viding the propelling force for the machine by changing its action to a horizontal instead of a vertical line but this form has not been illustrated.

The objects of my invention are to produce a mechanism by means of which planes or surfaces are constantly driven upward and downward along vertical lines and by which the downward traveling planes present their entire surface to the resistance of the air while the upward traveling planes present only their edges thereto. I attain these and other objects by the devices, mechanisms and arrangements illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a flying machine equipped with my elevating planes; Fig. 2 is a front elevation of a portion thereof showing the mechanism for actuating and controlling the elevating planes; and Fig. 3 is a side view thereof.

Similar numerals refer to similar parts throughout the several views.

The flying machine illustrated in the drawings comprises a frame 1 mounted on suitable running gear 2, with front and rear horizontal rudders 3 and vertical rudders 4, together with a suitable propelling motor 5 driving a propeller 6 whereby horizontal motion is acquired. The frame 1 is formed with fore and aft sections joined together at the top and bottom to form a stiff structure, the elevating planes traveling in the space between the fore and aft sections. A motor 7 is mounted in a suitable position and drives a shaft 8 by means of a sprocket chain 9. A counter-shaft 10 is mounted parallel with the shaft 8 and is driven thereby in the opposite direction by means of the gears 11 mounted on the two shafts. These two shafts 8 and 10 each drive one set of planes, one on each side of the machine, and since these two sets are exactly similar in form and action, but travel in opposite directions, the description of one such set is sufficient and the similar parts in the two sets will be indicated by similar numerals.

On each end of the shaft 8 (and 10) are mounted the small sprocket wheels 12 which drive the larger wheels 13 above them by the chains 14. These gears 13 are each secured to the outer ends of the short shafts 15 suitably journalcd in the frame 1. Similar gears. 16 are secured to the inner ends of said shafts 15. The small sprocket gears 17 are mounted adjacent to the gears 12, on the inner sides thereof, said gears 17 being the same size as the gears 12. The gears 17 drive the gears 18, loosely mounted on the shafts 15 between the gears 13 and 16, by the sprocket chains 19. Similar gears 20 are secured to the gears 18 and turn therewith on the shafts 15. The gears 18 and 20 are slightly larger than the gears 13 and 16. It is evident that the chains 14 and 19 travel at the same rate and that therefore the gears 13 and 18 turn through equal numbers of teeth in a given time, but since the gear 18 is larger than the gear 13 the gear 18 will rotate at a slower rate. Gears 21 and 22 are vertically over the gears 16 and 20 respectively and are of the same sizes and are mounted in pairs loosely on suitable shafts 23. Sprocket chains 24 join the gears 20 and 22, and other chains 25 join the gears 16 and 21. The chains 24 and 25 travel at exactly the same longitudinal rates but since the chain 25 is shorter than the chain 24 it makes a complete circuit slightly quicker than the chain 24 and hence it gains on said chain each time it turns over the sprocket wheels.

Taking now the fore and aft chains 24 and 25 into consideration: At suitable intervals on the chains 24 are secured small journal boxes 26 in which the central trunnions 27 of the elevating planes 28 are journaled. The planes 28 are of any desired shape and extend substantially across from chain to chain and their axles or trunnions 27 are parallel with the general direction of motion of the flying machine. A small gear 29 is mounted on each trunnion 27 and engages the chain 25 thereunder.

The action of the above mechanism is because the two pairs of chains 24 andv 25 are traveling at the same rate and the chains 24E carry the plane while the other chains 25 engage the gears 29 thereon, but as the plane rounds the wheels at the top or bottom of its course, the chains 23 gain on the chains 24 and cause the gears 29 to rotate and thus turn the planes through a certain definite angle. By selecting the sizes of the gears 16, 20 and 29 the plane can be made to turn through a quarter turn on its trunnions each time it passes over one of the gears, and by placing the planes in horizontal position on the downward traveling part of the chain they will turn automatically into a vertical position on reaching the other side of the circuit and will pass upward edgewise. Thus it will be seen that the planes 2S always act on the air during their downward stroke and are practically inactive during the upward stroke, hence by suitably spacing the planes on the chains a constant vertical reaction is maintained tending to lift the flying machine against the action of gravity, and this action will vary with the downward speed of the planes.

Since the axes of the planes are parallel with the direction of motion of the machine, they present practically no resistance to the forward motion thereof since their edges are always presented in that direction (Fig. 2). It will be noted that the planes turn pro gressively at each end of their travel, hence the side which is lowest during one downward stroke of a plane is uppermost during the next downward stroke of the plane.

It is obvious that many changes in the details of construction of the machine and of the planes can be made, and that the direction of motion of the planes might be al tere'd to suit other circumstances, without departing from the true spirit of my invention.

Having therefore described my invention, what I claim, is

1. In a flying machine, the combination with a frame; of an endless conveyer 24 supported by and traveling on the frame;

an endless controlling chain 25 supported by .and traveling on said frame and being at all points parallel with said conveyer 24:, but being of different length; planes 28 pivotally secured to said conveyer 24. at intervals thereon and traveling therewith; means 29 mounted on said planes and engaging said controlling chain 25 at varying points therein whereby said planes are controlled on their pivots; and means for driving said conveyer 24s and said controlling chain 25 at equal lineal speeds.

2. In a flying machine, the combination with a frame; a motor mounted thereon; a

shaft 8 driven by said motor; two similar sprocket wheels 12 and 17 mounted on said shaft; two concentric sprocket gears 13 and 18 mounted on said frame and being dissimilar in size and independently rotatable; sprocket chains 14 and 19 having similar links, but being of different lengths, said chain 14; connecting the gears 12 and 13 and said chain 19 connecting the gears 17 and 18, whereby said gears 13 and 18 are driven at different rotational speeds but at equal circumferential speeds; two concentric idle sprocket gears 21 and 22, loosely mounted on said frame, the gear 21 being similar to the gear 13 and the gear 22 being similar to the gear 18; two sprocket chains 24 and 25 GUSTAVE A.
