AERIAL MACHINE.

Application filed October 8, 1912. Serial No. 724,621.

To all whom. it may concern Be it known that I, Autos A. WYokoFr, a citizen of the United States, residing in the city and county of Santa Cruz and State of California, have invented new and useful Improvements in Aerial Machines, of which the following is a specification This invention relates to an air-ship, and

particularly pertains to an air-ship which combines the buoyant features of a balloon, the navigable features of an aeroplane,and which possesses the qualities and characteristics of a parachute.

It is the object of this invention to provide an air-ship in which gas is employed to counterbalance the weight of the shlp and for buoyant purposes and WhlCh is combined with planes for raising or descending, and for steerin in any direction.

A further ob ect is to provide an alr-shlp of the character describedwhich is simple in construction and operation, WhICh 1s adapted to be propelled by "motlve power and which is so constructed as to lnsure safe landing in event either the motive power stops or thegasescapes.

The invention consistsof the parts and construction and combination of parts as hereinafter more fully described and claimed, having references to the accompanying drawings, in which Figure 1 is a side elevation of the invention. Fig. 2 is an enlarged detail section on the line X-X of Fig. 1. Fig. 3 is an em larged section on the line Y-Y of Fig. 1. Fig. 4 is a detail elevation of theshock absorbing alighting gear. Fig. 5 1s a front elevation. Fig. 6 is a partial plan vlew. Fig. 7 is a detail vertical section of the gas container when deflated and employed as a parachute. Fig. 8 is a detail plan of a modified form of the gas contalner.

In the drawings A represents the-framework of the air-ship, which may be con structed of bamboo, aluminum, or any other light material. A gas bag or container 2, is formed of a pair of circular fabric portions connected together at their outer edges,

capable of being inflated so that it appears as shown in Figs. 1 and 5. This bag 2 ismountedwithin the framework A, with the peripheral edge of the bag 2 secured at frequent intervals to a horizontally disposed circular frame member B situated centrally of the machine, which circular frame B is chine, as shown in Fig. 1. At the extreme forward and rear ends of the parallel mem' bers of the framework are mounted transversely extending rock-shafts 3 and 4, respectively, each of which are rockable in their bearings and carry vertically disposed rectangular rock-frames 5 and 6- respectively. The rock-frames 5 and 6 are rigidly secured at their centers to the rock-shafts 3 and 4, and mounted on the top and bottom members thereof are superposed rectangular planes 7 which are horizontally disposed. The planes 7 are preferably curved upwardly from their forward edges back to a point near their longitudinal centers, thence curved downwardly and upwardly to their rear edges, thus being substantially ogee in cross section; the tips of the planes being on a plane with the swelled portions thereof. The planes 7 are thus formed to present resisting surfaces to the the machine up and down; the curved formation of the planes acting to quicken their action. The planes 7 are so arranged on each frame 5 and 6 as to be disposed one above and one the bag 2, as a means for enabling currents of air being directed above and below the gas bag when traveling horizontally or directed either above or below the gas'bag when traveling in an inclined direction and when the'planes are'tilted. These planes 7 are adapted to be operated separately or in unison by rocking the frames 5 and 6 by means of cables 8 and 9 passing over direction pulleys 11, andwhich are secured to the inner,-upper and lower edges of the rockframes 5 and 6; the cable 8 being attached to the lower edge of the rock-frame and the cable 9 to the upper edge. The cables 8 and 9 after passing over the direction pulleys 11 are connected to any suitable device whereby they may be operated to rock the rockframes 5 and 6. They are here shown as Patented Jan. 20, 19.14.

arallel frame 60 air to aid in directing 85 below the peripheral edge of 90 propeller connected to levers 13; the cables 8 being attached to the levers on one side of their fulcrum points, while the cables 9 are attached to the levers on the opposite side of their fulcrum points. By this arrangement, when either of-the levers 13 are rocked, one cable will be let out while the other will be taken up, thereby rocking the rock-frames '5 and 6 to tilt the planes '7 at various angles, according to whether it is desired to direct the machine up or down.

A motor or engine 14, of any suitable description, is located rearward of the aviators seat 15, and is designed to rotate vertical blades 16, arranged beneath the gas bag 2 rearward of the center thereof, in either direction so that the vessel may be caused to travel forward or backward; a horizontal lifting or helicopter blade 16 being disposed beneath the machine to assist in moving it in a vertical direction.

A fabric plane 17 is mounted on the lowermost portion of the framework A beneath the seat 15 and engine 14, and extends transversely across the machine. The forward edge of this plane 17 is inclined upwardly so as to give it a tendency to lift on the air during flight. This plane 17 also serves as a shield or screen beneath the aviators and passengers seats, and as such lessens the effects of height on the occupants of the car, as they are prevented from looking directly downward beneath the ma-. chine while in flight.

The capacity of the gas bag 2 is intended to be sufficient to lift and buoy the vesse so that the engine 14 and propellers 16 will not have to be depended upon for lifting purposes. At the same time, the lifting power of the engine 14 and propellers 16 is to be great enough that in-event the gas should escape from the bag 2, which would cause it to collapse and form a plane or parachute within the framework A and circular frame B, as later described, the machine would still be capable of making a flight. If it should occur'that the engine be stopped and the gas released at the same time, a safelanding would still be. insured by reason of the parachute action of the deflated bag 2.v

In navigating the aerial machine, the op erator raises or lowers the machine by tipping the planes 7 by means of the handlevers 13, as before described; the rear edge of the rock-frame 5 being moved downward and the front edge of the rock-frame 6 tipped upward in order to direct the ship in an upward direction, this action being reversed when it is desired to move in a downward direction. A rudder 18 is vertically disposed on the framework A between the propellers 16, the turning of which from side to side by any suitable means through a pair of cables 20 and 20', enables the operator to steer the ship from right to left, as desired; the rudder 18 being placed between the propeller 16 so, that the currents of air induced by the latter will be directed against the sides of the rudder when it is turned from side to side, thereby quickening the turning or steering action thereof. A vertical stabilizing fin or lane 2 extends along the longitudinal center of the gas bag 2on the upper and lower side thereof rearward of its center; the fin 2 being supported on the framework A so as not to interfere with the deflation and collapsing of the gas bag 2. The framework A is fitted witha suitable shock absorbing alighting gear which is here shown as consisting of a pair I of wheels 22 disposed in alinement on the longitudinal center of the machine, at the front and rear thereof, and a pair of wheels 23- disposed between the wheels 22 on the opposite sides thereof. Each of the wheels 22 is mounted on a lever 24 fulcrumed on the lower end of a vertically extending rod 25 mounted on the framework A. The outer end of the lever 24 is connected to a sleeve 26, slidably mounted on the rod 25 by means of a helical spring 27, or .other yieldable member, as particularly shown in Fig. 4. The sleeve 26 is normally retained in a limited uppermost position by means of a helical spring 28 wound on the rod 25 beneath the sleeve 26. The helical spring 28 'bears between the sleeve 26 and a similar sleeve 29 'slidably mounted on the rod 25; the sleeve 29 being connected to the inner portion of the lever 24 by means of links 30. By this construction, when the lever 24 is rocked upward on its inner end, the sleeves 26 and 29 will be moved toward each other, in opposition to thespring 28; the downward movement of the sleeve 26 being governed by the tension of the spring 27. The springs 27 and 28 thus act in conjunction with each other to cushion the rocking movement of the lever 24.

- The gas bag 2 is fitted at its highest point with an escape valve of any suitable construction, the opening of which allows the gas to escape from the bag 2. This valve is here shown as consisting of a disk 31 slidably mounted on a vertically disposed standard 32, which standard is supported on the framework A and projects upward through the gas bag 2. The disk 31 is adapted to seat on a rim 33 attached to the gas bag 2, and is normally held in its closed position by a helical spring member 34 on the standard 32 and by the pressure of the gas on'the inside of the bag 2. It is designed to be actuated to release the gas in the bag 2 by means of a cord 35 nects with a pin on the disk 31, extending through vertical slot-s formed in the standard 32; the cord 35 passing through the interior of the standard. y

which con- When the gas bag is deflated while the machine is in flight, the lower portion of the bag collapses against the upper portion. The upper and lower sections of the bag 2,

by ieason of being formed in the shape of opposed segments of spheres connected together at their edges, will assume the shape of a parachute, as shown in Fig. 7, when the lower section reverses on exhausting the gas from the bag. As a means'for preventing oscillation of the machine when the parachute is thus formed, it is necessary to provide an opening at the highest point of the bag 2 to allow air to pass from the underside of the parachute to the upper side thereof at its center. As a means for accomplishing this, an opening 36 is formed in the lower section of the gas bag 2 around the standard 32, which opening is closed by means of a valve 37, when the gas bag 2 is inflated.

The valve 37 is in the form of a disk or plate, slidably mounted onthe standard 32 and supported upon a helical spring 38 bearing against a collar 39 on the standard 32. When the gas bag 2 is inflated, the valve 37 contacts the rim 40 of the opening 36, as shown in Fig. 2, which rim 10 is held in tight contact with the plate 37 by means of the spring 38 and hook members 41, which are mounted on the rim 40 and are temporarily tied to the collar 39 in such manner as to be easily released.

Upwardly extending projections 42 are formed on the rim 40, which are designed to contact the rim 33 of the valve on the upper portion of the gas 'bag'2 in such manner as to separate the rims 33 and 40, where the upper and lower portions of the gas bag are collapsed together to form a parachute, so that when the valve 31 is open, air may pass from the underside of the lower portion of the gas bag through the opening 36 and the valve 31, as indicated in Fig. 7.

It is manifest that while I have shown and described the gas bag 2 as formed of two concavo-convex sections, that it may be formed of any other shapes and in any suitable manner, which when the bag is deflated will form an umbrella shaped structure or parachute and when inflated will be comparatively flat and elliptical in cross section, and which, whether inflated or deflated will act as a plane for supporting the machine in the'air. For instance, the upper and lower portions of the bag may be formed of sub- .stantially flat flexible material of any suitable out-line which, when deflated, will form a plane, and when the machine is moving downward will assume the shape of a parachute; or it may be formed with the upper and lower portions in the shape of segments of spheres either formed integral or connected together at their edges. In the latter instance the upper portion may be made rigid if desired; the essential feature being that the lower portion be flexible so that it can attain either a concave or convex shape in relation to the upper portion, according to whether the bag is being employed as a balloon and gas container or as a parachute and plane. It is also manifest that while I have described the gas bag as circular in plan, that it does not necessarily have to be in this exact form, particularly where the end planes 7 are employed, as it may be nearly circular or elliptical, as shown in Fig. 8, or in any other suitable outline.

As a means for insuring stability, a series of flexible partitions 2 may be formed between the upper and lower portions of the bag 2 if desired, thus dividing the space within the bag into a series of compartments, each of which is provided with a suitable escape valve 2, by the opening of which the gas therein may be released.
