The rib members 25, which are also formed out of comparatively light metal, for the purpose of strength, are in the nature of inverted T-irons, as clearly shown in Figure 13 and pass through the corresponding slots formed in the web of the keel. portions or laterally disposed flanges of the ribs are riveted or otherwise suitably secured to the lower side flanges of the keel I-beam as shown at 26'in Figures l2 and 13. The ribs are bowed, as shown in Figure l0, so as to provide a suitable bottom for the air ship and these ribs are preferably formed to extend continuously about the air ship, with certa-in of the ribs constituting the supporting frame for the deck floor, namely the ribs 25a, see Figure l0; while the ribs 25 constitute a support for the ceiling of the deck and therefore a vsupport for thebottom ofthe gas chamber holding compartment; 'while some of the ribs are formed to extend over this gas chamber holding coinpartment, namely the ribs indicated at 25C in Figure 10; a fourth set being formedto provide support for the roof or parachute, namely the ribs 25d; and a fifth portion or set of the ribs are formed to extend across the outside of the roof, namelythe ribs indicated at 25e in Figures l and 10. That is to say, the ribs are alternately formed of different lengths so as to constitute the various portions just described, whereby all support and pulling strains are transmitted to the keel proper.

The portions of the ribs for supporting the ceiling, namely the ribs designated at 25h, are also `connected with a longitudinally disposed beam 27 extending full length and at the longitudinal center line of the ship. The ends of the longitudinal beam 27 are connected with the ends of side frame members or ribs 28, which are bowed outwardly intermediatexof the ends. where the ribs 25 are connected thereto. This ceiling frame, composed of ribs 25, longitudinal rib 27 and the two side bowed ribs 28, is also supported from the keel by the vertical members or posts 29.

The frame of the ship alsov consists ofthe outwardly bowed side rails 30 to provide the K desired shape or contour to the ship; the

side rails 3() being secured at their ends to the upwardly curved ends of the keel; and

the bottom 'frame portion of the ship also consists of the longitudinally disposedbottom rails 3l arranged in spaced relation with their ends preferably connectedy at the junci ture of the keel and side rails.

All of the rails are preferably formed Vof comparatively light metal and T-shape in cross section so as to have the necessaryk strength; the rails and ribs being bent by heat treatment, while the ends of lthe ribsV are preferably welded together to provide a The inverted head.

'deck of the ship; the hatchways beim continuous one piece structure. rlhe ribs are arranged and connected `asdescribed with the fiat surfaces or head portions disposed outwardly so as to provide a flat surface or support for the sheet cover material. To afford proper support for the deck I show the lower portion of the frame, namely Vat a point below the 'main floor or deck of the ship, provided with arcuate braces 32, preferably also of T-shaped metal, see Figures 10 and 1l, extending from points adjacent to the forward and rearward ends of the ship and bowed toward the truss 2l to which the intermediate portions are riveted or otherwise secured. y

rlhe air ship involves the-hatch and lading receiving lower portion indicated generally at A in Figure 3, in which the engine or inotors are also located; the deck portion indicated generally at B; the gas tank or chamber compartment or portion indicated at C; and the air chamber or portion indicated at D. It will be understood,rof course, that the youtercovering or walls may be of any suit-A able water resisting material and suitablysecured to the frame members. `The hatch or lower chamber A of `the air ship is also shown provided withvsuitable tie rodsor wires at 33 and this chamber or portion A at the ends is provided with suitable supporting frame .members connected to the keel truss, to which the high speed motors generally indicated at 3ft-in Figures 3 and 5 are secured. The motorsy drive the propellers shown at 35' andl provide power for loperating and controlling the wings and other elements to be described and the` motors are, of course, under the-control of theoperator fromthe pilotshouse or chamber 3G located at the forward end of the air shipin the deck con'ipartinent or portion. I Y Y The hatch A at suitablyspaced intervals is preferably provided with partitions as at 37 to divide the hatch into a series of suitable chambers for the purpose of holding the lading in` its predistributed` manner so as to properly distribute the weight throughout the ship and maintain its equilibrium. The partitions 87y are preferably formed of heavy wire for the purpose of lightness; and the lading holding chambers are disposed on opposite sides of the Vlongitudinal center line of the air-shipiand accessible by hatch-r ways indicated at 38 in Figure. (i, from the g provided with` ladders 39.

The deck portion B of the air ship is formed by the ribs 25d to whose flat upper surfaces suitable Vplate or sheet material is secured; the deck being formed to provide acontinuous open ended passage from front to rear of the ship; the forward end of the passage opening onv opposite sides of the pilot house 36. This arrangement provides an air passage all the way through the ship CTI from the front `to rear. The air ship o n opposite sides of the lonGitudi-nal center line is shown provided with suitable cabins or state-rooms as shown at 4() inFigure'S, at the rear or stern end of the ship and located in the spacing indicated at40 in Figure 4.l The side Wallsof the air ship' extend a distance forward of the state-rooms 40, namely to the point indicated at 4l in Figure 4, thus leaving openings on opposite sides of the pilot house 36 communicating with or constituting a portion of the continuous opening through the air ship; the airV pas-A sage converging toward the rear end as shown in Figure 4. rlhis permits rair to rush through the passageway andfout througli'tlie rear end, discharging on opposite sides of the rudder indicated at 42 .in F igures 3 and4.

The ceiling of thedeck portion B, at a point just forward of the state-room chainbers, namely at a point substantially onethird of the distance between the bow and stern, is given an upward .bulge or arcuate formation as shown at 43 in Figure 3 to provide an air pocket above the main pai't of the air passage. This pocket at 43 acts as a vacuum chamber when the air rushes through the passage Way and tends to assist in the lifting of thevair ship. p

The portion of the air passage in vertical alignment With the vacuum pocket 43 is shown provided with a suitable number of Wings or planes 44 arranged one above thek other, as for example three, extending, preferably, `entirely across the deck and two upper Wings rigidly .secured `in placejthe planes being bent downwardly toward the rear end at the regulation or proper angle as shown in Figure 3 in order that the air rushing inwardly through the forward end of the air passage when encountering the Wings 44 Will assist in lifting the ship. i

The ends of the upper Wings mayV be. se-

cured to two ofthe vribs of the framevvork and supported" or braced in any `'suitable manner at intermediate points by means of the rods 44a, see Figure 6, secured tothe truss-Work below the deck so that the lifting strain may be transferred to. the keelland main framework'. Y y i The lower Wing 44h is not fastened at its ends to the ribs of the ship, but has its forjward edge liingedly secured in any suitable manner-as at 44c in order to perinit'this ning to be tilted to varying degrees downwardly. The purpose of so mounting the- Y lower ving is to offer greater resistance to `the Wind pressure through the deck passage, andthus assist in elevating the ship, Without the necessity for Aa long glide along the ground. At the `same time, it is apparent that a downward tilt of the Wing `When alighting Wil-lalso tend to provide aquick stop, Without employing the `parachute portion of the ship, (later to be described) for av vertical descent.

intervening air passages 46, see Figure 3.

These passages' 46 extend from the air pas-v sage through the shipy to the air chamber 47 immediately beneath. the roof 48 of the ship. The chamberv47 extends through'outA the entire upper portion of the airv ship from end to end and side to side as shown to forni a parachute portion. The gas chainvbers `or tanks rwhich located on the ceiling are secured in place against any movement or shifting and are also held in place bythe supporting ribsd,` which extend across the tops of the tanks and the tanks are shaped tok conform to the upper portion of the ship adapted to'oifer'aslittle resistance as possible. Filling cocks for the tanks may extend through the ceiling of the ship so as to be easilyr accessible. p

:The ceiling portion of the deck at points in` alignment with the vertically disposed air passages 46, as Well las the vacuum chamber portion are provided With series of openings as at 497see Figures 2 and 3, in the nature of ventilatorsv or air-tight closures. These ventilators are preferably all operatively connected together, see Figure 2, so that any one or all of the series of ventilators 49 mayV be Ysimultaneously opened'l or' closed by suitotherwise operated.

The roof 48 of suitable light metal sheeting'overhangs the sides of the air ship and connects with an extendedportion of the ceiling and Vthus extends theV parachute portion 47beyond the sides of the main portion of the air ship as shown at 5() in Figures l.

and 2. This overhanging portion-of 'the chamber 47 kis provided with a -nu'mber of ventilators in vthe bottoni as lshovvn at 5l in Figures 1 and Q disposed throughout the lower part of the over-hanging portion vof the air chamber 47. The ventilators 5l may have slidably mounted closure members all operatively connected together by means of a suitable cable or chain as at`52 so that simultaneous operation of the ventilatorsy may be `had from a- Icommon point. VThe aber? the ai? Shir; the leverend of the tie' wires being suitably connected to the lower ,or deck framework vof the air ship.

The roof 48 at suitable intervals is shown provided with a number of vents as at 54l whereby air may gradually be permitted to escape from the parachute portion 47.

The air ship may be .provided with any suitable number of propellers 35 both forward and aft; and the air ship at suitable points is shown provided with side wings or planes 55 of suitable construction and size, and preferably hingedly inounted'as at 56, see Figures l and 6, so as to permit the wings 55 to fold upwardly against the sides of the air ship. The pivotal point or hinge for the wings may be slidable on the bracket members 57 secured rigidly to the sidesof the air ship.

The pivoted inner edge of each wing 55 may be controlled by means of a chain or cabler 58 the ends whereof are secured to the wing or 'to its hinge connection; the chain in turn passing about the upper and lower pulleys 59 and 60 and about a suitable windlass as at 6l. rhe windlasses 6l at both sides of the ship may be operated by any suitable mechanism and preferably by means controlled from the pilot-house so that the wings may be separately operated or kbot-li wings operated in unison. Vith the cables wound on the windlasses in one direction, the pivoted ends of the wings will be drawn down on the guide or bracket-mem-V bers 57 and held in place when the windlasses are locked against rotation; and the.

outer ends of the wings are maintained in place by means of the brace rods or arms 62, y which are liingedly secured to the wings andv to the sides of the ship.

The air ship is also shown provided at the forward or bow end of the ship with additional wings or planes as at 63, see Figure l, preferably arranged at a point in alignment with the ceiling of the deck and therefore just above the air passage through the air ship; while the rear or sternv end of the ship is also yshown' provided with wings 64 one above the other, preferably arranged in pairs on each 'side of the rudder 42. AThe wings of each pair are supported by any suitable frame, as at 65, with the frames of both pairs provided 'with an operating'V rod GG which will permit simultaneous warping or inclination of the wings 64; the operating rod 66 being' controllable from the pilot house by any suitable operating mechanism not shown. v n The movable wing 44h located on the deck l may be controlled by any suitable mechanism controllable from the pilot-house, as for eX- ample by means of a chain or cable 67 secured to the rear lower edge, (see Figure 8) y and a chain or cable 68 secured to the upper rear edge; the cables in turn passingV about properly supported pulleys G9, above and belThe two elevating planes 63 at Vthe for-r ward end, like the planes 64 at the rear end,

are hingedly secured in place and all of the planes or wings are preferably operatively connected by suitable operating mechanism, not shown, so as to permit simultaneous operation from the pilot-house.

The hull of the ship is shown provided with closable port-holes 71; and the bottom is preferably provided'with suitable yieldably mounted skids 72, see Figures 3 and 6. l/Jliile my air ship is especially designed to alight on and ascend from water, the skids held by means of sprint3 ingon a flat surface such as ice.

The upwardly bent portion 43 of the ceiling provides a vacuum, or semivacuum, as the air rushes through the passageway, which it isbelieved will assist in ascending. The upper part of this pocket 43,*like vother portions of the ceiling, is provided with the controllable ventilators 49. These ventila- Vtors are opened up so asto permit air to enter the chamber or compartment C above the ceiling and thus bring the parachute portion of the ship into play when descent in a perpendicular manner is desired; the parachute portion being provided as a means of safety to permit a {J-Jraduall descent to be made. The vents 54. in the roof or top ofthe ship retard the outiiow as these vents have relatively small openings for airescape.

The outside thin metallic covering of the example shown at T3 in Figure l the canvas being provided with stiii'eningslats or rods whose ends may ride in suitable grooves above and. beneath the curtain; the free ends of the curtains toy be fastened in any suitable niannersoas to maintain them in passage closing position when desired.
