AIR-SHIP.

SPECIFICATIQN forming part of Letters Patent No. 383,889, dated June 5, 1888.

Application filed May 5, 1886.

To (LZZ whom, it may concern:

Be it known that I, EDWARD P. JOHNSTON, a citizen of the United States, and a resident of Decatur, Morgan county, Alabama, have invented a new and useful Improvement in Air- Ships, of which thefollowingisaspecification.

My invention relates to improvemcntsin airships, having for its objects the provision of means whereby a ship of the class named may be caused to ascend to different desired elevations, to be maintained in horizontal position as regards the earths surface while in operation, to be propelled in a forward direction or held in stationaryposition, and to descend at the will of the operator.

To the accomplishment of the above ends the invention consists in an air ship having from such position may be instantly made.

known to the operator.

The invention further consists in means for holding the ship to any predetermined course and for changing such course when desired; and, finally, the invention consists in the construction, arrangement, and combination of the several parts for service, substantially as hereinafter described, and specifically pointed out in the claims.

In the drawings, Figure 1 represents in per spcctive an air-ship constructed in accordance with my invention. Fig. 2 is a top plan view thereof. represents a side elevation of the ship asitappears when in operation. Fig. t is a transverse sectional view taken on the line a; a: of Fig. 2. Fig. is an enlarged detail sectional view of one of the wings and its attachments detached from the ship. Fig. 6 represents an enlarged detail perspective view of a portion of the corrugated bottom of the ship. 7 represents a modified form ofthe parts shown in Fig. 6. Fig. 8 represents an elevation of the device for automatically maintaining the ship in equilibrium. Figs. 9,10, 11, 12, and. 13 are detached detail views of parts of the structure and operative mechanism.

Referring to the drawings, in which similar letters of reference denote similar parts, A designates the hull or body of the ship, having top a, flanged or corrugated bottom c,and sides a formed of suitable material, properly supported and extending for the greater part of their length in planes parallel and at right angles with each other. (See Figs. 2 and 3.) The opposite ends of the hull terminate in wedge'shaped portions b 1/, formed at the forward end, b, by the converging forward ends of the sides a and at the rear, I), by the converging rear ends of the top and bottom (L a.

B B designate inclined sections which are rigidly secured to and project outwardly from the opposite sides of the hull, and extend forward from the front of the same in planes parallel with the transverse end at an angle with the longitudinal axis thereof to form an inclined plane at the front and at each side of the hull,which planc,being propelled against the atmosphere, in the mannerhereinafter described, will, through the upward pressure which is thus produced against said inclined plane, assist to sustain the ship while in the air. The upper and undcrsurfaces of the sec tions B Bare formed of narrow strips or plates 44, of suitable material, securely fastened to ribs or timbers 45,(see Fig. 12,) which extend outwardly from the hull between said strips, and the outer edges of said sections converge at the forward end of air-ship, as shown in Fig. 12.

Udesignatcs an upwardly-proiccting guide plate or blade that extends from front to rear, and is secured at its lower edge to the upper surfaces of the hull and forward part of ship upon a line equidistant from the side edges thereof. Flanges, as a 0, may, ifdesired, be secured to and project outwardly from the opposite sides of the gnideplate 0, extending from end to end in planes parallel with the top of hall, for a purpose hereinafter described.

D D designate additional guide plates or blades that project upwardly from the top a at each side thereof to operate in conjunction with the central guide-blade, C, as will be presently explained.

E designates flanges rigidly secured at their upperedges to and projecting downward from the lower surfaces of the sections B Bin planes parallel with the side edges .thereof. Thebottom of the hull A may also be provided with similar flanges, although in the drawings the bottom of said hall is shown as corrugated, it being understood that wherever rigid flanges E are shown corrugations similar to those shown in Fig. 6 may be used interchangeably with said fixed flanges E. v

E designates similar but wider flanges that are hinged to the lower surfaces of said fixed inclined sections B B at the outer edges thereof, and provided with upwardly and laterally projecting arms 6 6', (see Figs. 7 and 9,) to which are secured cords e e which extend over pulleys to an operating-wheel in the interior of the ship, by which said flanges E may be swung from their normal vertical position upward into the plane of said sections B B, or downward to a vertical position, as shown. The fixed flanges E, or their equiva-' lents, operate in conjunction with the movable flanges E,when in vertical position, in giving steadiness and permanency of direction to the air-ship.

The movable flanges E are hinged to the outer edges of the fixed inclined sections B B, and when swung outward into the plane of the fixed sections increase the area of the inclined lifting surface. This feature comes into play when the ship is accidentally eareened toone side or the other by reason of sudden air currents or otherleauses. The movable flange E on the side of the ship that is lower is then to be swung outward and upward, and by the increased inclined surface which the air will then have to press against on that side the ship will be quickly righted again.

F designates a rudder that is hinged to, the forward end of the air ship and is operated by a wheel in the interior of the ship by means of the cordsf, that extend thence to the rudder, as shown.

F designates a similar rudder hinged to the rear end of the hull and operated in a similar manner from the interior of the ship.

The sections G G, Figs. 2, 4, and 5, each consist of a series of slats, g, which are hinged together at their edges (see Fig. 11,) and provided at each alternatejoint with upwardlyprojecting studs 9, that are secured to the hinges and extend thence through slots it, formed in the hollow supports H, and are within said supports provided with T-shaped ends. (See Fig. 10.) The studs 9 are within the hollow supports each connected with the coils of springs t, which keep these movable sections extended, exceptwhen drawn in, (for purposes hereinafter set forth,) by means of rods I, which extend from the outer ends of said springs to the interior of the ship. (See Figs. 5 and 10.) The supports H may be braced in any desired manneras,forinstance, by braces if, that extend from the fixed sections B B to the outer end of the forward and rearward supports-and also, if desired, by iron rods extending from the ends of supports H on eachside of air-ship to the top of guide-blade O, with perpendicular supports under the points ofjunetion, as shown by dotted lines 10 in Fig. 1.

I will now proceed to describe the means whereby my improved ship is caused to ascend, to move forward or remain stationary in the air, and to descend therefrom at the will of the operator. To these ends I employ a series-preferably six in numberof propellers, K K, two of which I mount at the rear of the ship upon horizontal rotatable shafts 7c, journaled in bearings within and near the sides thereof. The remaining propellers K are mounted upon vertical shafts 7c, journaled in bearings k secured to the .upper surfaces of the fixed sections B B at points equidistant from the sides of the ship and the outer edges of said section near the opposite ends of the hull of air-ship. For convenience of description, I will hereinafter designate the liftingpropellers K as 1, 2, 3, and 4. Said propellers may be operated by any desired mechanism-as, for instance, inthe manner shown in the drawings, which consists in providing the shafts 70 below the propellers with bevel gear wheels and operating the same bysimilar gearwheels mounted upon rotatable shafts 7r", that project from the hull A.

I have not deemed it necessary herein to show any particular means for imparting motion to the shafts k k, inasmuch as any desired motor may be employed for such purpose. Each propeller is provided with an independent motor.

I provide for the automatic maintenance of the ships equilibrium by causing any inclination of said ship from its normal horizontal position to set in motion mechanism whereby additional force and consequent increased speed is imparted to the liftlllg-plOI'lf-ZIIGFS on that sideor end of air-ship which may be temporarily depressed, thereby restoring equilibrium. This I accomplish in and by the following-described manner and means, viz:

L, Fig. 8, designatesasuitablesupport having a top, Z, provided at its middle with an aperture, 1, and at its rear side with an upwardly-projecting back, Z".

M designates a rod hung upon suitable pivots, 972, within the aperture Z, so as to move freely to the right or left by the force of gravitation when the air-ship is inclined in either of these directions. Below the top Z at m the rod M' moves freely on pivots m, placed at right angles with pivots m, but is confined on each side by the parallel plates or guards m so that while thelower part of rod M can move freely upon said pivots m at right angles with the plane of motion of the upper part of the rod, yet when moved in the same plane of motion as said upper partit is held by theguards at", so that the upper part of rod M mustmove with it. Rod M may either bejointed,as described, or entire. This rod is provided at its lower end with a pendulum, 1n, and near its 2: slit 3 of metallic contact plates p, adapted to F engaged by said circuit-closers, and each of said contact-plates is connected by a conductor, p or p, with an electro-generator, R. As will be understood, deviation of the ship from its normal position and in the direction shown by arrows 5t) andfil, in which the pendulum swings, will, through the inert. ill of said pendulum, bring one or the r of the cireuiteloscrs N N into contact ithone or more of the metallic plates 1) or 2)", thus throwing into circuit one or the otheroi' the conductors 0 or 0, thereby causing the motor-controlling mechanism to which the conductor so in circuit is attached to operate with greater or less force, according to thenumber of plates 2) orp, and the consequent battery force in contact with the circuitelosersand by which any one or more ofihe propellers l, 2, 3, or 4 may have increased speed and consequent elevating power imparted thereto.

As the rod M has a swinging motion in but one direction via, parallel to the face of the support, as shown by the arrows 50 and 51- two or more devices similar to that above de' scribed will be required to fully control varia tion of both the longitudinal and transverse axes ofthe ship. From their proper normal position said devices aresetso thattheplane ofmotion of their respective pendulum-rods shall be at angles each with the other. The regulater whose pendulum swings crosswise of the ship will control the two groups of propellers 1, 3, and f2, The regulator whose pendulum swings lengthwise of the ship will control the two groups of propellersl 2, and 3 at.

The upper end of the rod M above the crosshead moves upon the face of a graduated curved plate, in, secured to a block, hi projecting from the back Z", for the purpose of showing the distance the ship has moved from its normal position. To show any deviation of the red M itself from the vertical plane, I provide a level, m Fig. 3, securing the same to the middle of the cross-head m, as shown.

The operation of my improvements is as follows: Qljower is first applied to the liftingpropellers l, 2, 3, and et for the purpose of raising the ship to the required elevation. Power is then applied to the rear propellers, K, to move the ship in a forward direction, which power is gradually increased until the ship is principally or wholly supported in the applied to any one or more of them for the 75 purpose of maintaining the equilibrium of the ship. To aid in the accomplishment of this, the movable sections G or lr on the elevated side of the ship may be reduced in extent, so as to oppose lesslit'ting surface to the upward pressure of the atmosphere by drawing in the rods I, and thereby contracting the springst' and partially or wholly folding together the hinged slats g as illustrated in Fig. 13. The result of this reduction of surface is to lessen on that side of the ship the amount of upward sustaining'pressure due to the resistance of the inclined surface to the air, and the ship immediately careens toward that side. It will be noticed that the effect of reducing the surface of the folding sections G Gis just the opposite of that produced by swinging outward the movable flanges E. These two features ofconstruction may therefore be regarded as alternative arrangements, though both can be used with advantage and a combined effect obtained. By thus increasing the inclined surface on one side of the ship and reducing it on the other, or vice versa, the equilibrium of the machinecan be easily maintainedindependent-of the control given by the independent liftingpropellers 1 2 3 t.

It will be observed that the longitudinal cerrugations or flanges upon the under surface of the hull and fixed sections, and also the central guide-blade, G, and side guide-blades, D D, serve to give steadiness to the air-ship and to aid the rudders in holding the ship in any predetermined course.

To descend, the speed of the lifting-propeh lers is gradually increased and at the same time that of the driving propellers is gradually de creased, until the ship is wholly supported by said lift-irig-propellers and becomes stationary, at which time the speed of said lifting-propcllers is slightly diminished for the purpose of causing the ship to descend to the earth.
