.Z'o all whomit-mag concern.-

ii it known that 1, JOHN G. E, Bsxu iL- sou, a subject of the liling 0t Sweden residing in the city of Umaha, county of llouglas, and State of Nebraska, have invented certain new and useful improvements in Airships, of which the following a specification.

lily invention relates to aerial navigation and has pzr'ticular reference to the heavieriluma ir type at air-ships.

The objects of the invention are to secure increased. stability, security strength or" con sit-action, and better coi'rtrol in the aeroe type of air craft. With. these objects in view my invention eonsistsin the novel construction, combination and arreugcment or" parts, all hereinafter (lescrilw. etail, illustrated in the accompanying drawings and particularly pointed out in the appended claims.

In the drawings-Figure 1 is an end eleation of an aeroplane embodying my inention. Fig. 2 is a side elevation thereof on a reduced scale. Fig. 3 a plan flQW "hereof. Figs. 4:, 5 and 6 areenlarged detail views broken away.

in the construction herein shown two sets of planes or wings are shown., these wings ng; curved upwardly to slightly elevate cu outci edges and improve the stability of the ship. The we sets of wings or planes and the rear steering mechanism are arranged at (lifiereut Ql8l2li0l15 increasing ri-arwardly, in order to give each of planes a comparatively undisturbed stratum of air to movein, that is undisturbed so as the movements of the other parts of the ship through the air are concerned. The fiorwartl lllfllleS will create certain vertexes or other disturbances of the normal condition, of the body of the atmosphere, but said 'tor'warrl planes are moving through a lower level of atmosphere than the rear carrying or mining planes these created. air currents will largely take place below said rear planes 1 i itateu l aving the latter a (.(llflpzllfitlifi )(Hly of air to work in. The two 5 or carrying planes are mot-uh nouns-1y to i evate or lower the 5 prevents the accidental e (lWlSE the craft and mai tains its while rising or ii tal steering plane is 'therefi'ire eniuloyed chiefly for the mere adjustment of slight in equalities in height between the "forward and rear end.

At their forward ends the sides 2 and S are secured to a vertically disposed truss-frame 12, he side portions of which air labeled, respectively, 13 and 13.. To the upperencls' the sides 13 and 13 of this truss-f corners of lllOlT and. 16 in Fig: 1

n set of carrying planes P ateering plane A 011 a web 19 of a segmental worm-gear rack t which is shown on an enlarged scale in Fig. i), by means of a series of radial rods 21, E22, and 24, which extend from the web 19 of the gear segment to the rhoinboid shaped framcll in the one instance and the similarlraif 18 for the rear ydanes 9 and 10. A description of the supports for one of these frames will therefore 'uilici'itor both. he framell, or

From each side of ifrom each of the pair of sides of the frame 14' divided apart by the 'oraoe -bar 17, the

series of rods 21 to 24 converge to the web 19, as shown substantially in Fig. 4, the rods from the opposite $1Cl of the web being arranged as duplicates of those seen on the near 'side in Fig. +l. In other nords the elements 19 to 24' of F ig. 4 appear alike from both sides, aoh of the rods 21 to 24- being duplicated.

The geansegment 20 is in mesh with a worm on a shaft 26 mounted in suitable hearings on a cross-bar 27 which spans the space between the lower ends of the sides 13 and 13 of the uprighttf-ront truss-frame. On the shaft 26 is heyetl". i1 bevel pinion 28 which meshes with a larger bevel gear 29 keyed to a shaft. 30. The latter journaled in bearings 31 and 32 which rise from the cross-bar adjaeent to the hearings for the shaft. 26 On the shaft is keyed a sproolzotwheel which is driven by a sprrwliet nbain Ehtfroi'n a sprocket-Wheel 35 Which-i hstantially a duplicate of the wheel Sit ,l] .yhiielgiifi is keyed to one end of a. shaff it; niountedin a healing-frame 37 on which the seat 11. mounted between the aides 2 the vessel in an suitable manner. Near the opposite end of the shaft: is placed a sec nd sprocket. wheel 38 from which leads a sprmrlcet-ehain 39 to a aproeket-ivheel '1) f a similar spiroeltetovlieel and chain mechanimi for the rear planes 9 and R0. The shaft 36 is rotated by the opera tor by means of a. hand-wheel -10 keyed to said ahatt. Through the Sprocket-wheel and chainoonneetiona between said shaft an d the planotilting' mechanism for each plane shown in Fig. 4, both forward and rear planes are tilted in the same'oirections when the hand-whccl 4-0 is rotated. The uprightsupporting-irame on which the wings 9 and 10 are piv'opd by their rhonihoid frame 18 is substantially identical with the frame 13 for the iforuuird wings. and is dintingruishcd from said .ii'ranie l2 by heiug labeled 41.

These lti lllS are in mesh with bevel gears 4.8 2 l as on shafts 4:9 and 49' mounted in the ends 2 and The latter shafts are ange opening in the former. Therotated by means of pulleys or sprocket- "wheels 4!) and the latter are rotated from the operatons seat by cords, cables or sprocket-ohains 50 and 50 which are led in any suitable manner over pulleys to a pulley 51. on the lower end of an upright shaft 5:2 (Fig. 6) placed in front of the drivers seat 11 (Figs. 2 and 3 50 and :30 in Figs. 1, 2 and 3ofep'esent separate runs or legs of the flexible eonnec' 'tion 50 shown on thepulley 51 in Fig. 6. The details of arrangement in running this connection from the pulley 51 to the pulleys ell) and. back to the pulley 51 may be varied in any desired manner and form no part of the present inventiou- The shaft 52 has on its lower end a reduced journal portion journaled in a bearing 5-.l on the frame-work 37 mounted between the frame-hides 2 and 3 as indicated in Fig. 3. 'lhe'fshaft 52 is telescoped by a hollow shaft 55, which, together with the shaft 52, is supported laterally by a hear-- ing These two shafts are rotated by a hand-wheel Iii-which is rotatively mounted with relation to both the shafts and has normally released or releasable connections whereby said hand wheel may be keyed to either or both shafts to adjust either the stiaeringg plane 414 or the rudder 7 or both. Thus. referring, say, to Fig. 2 the operator. controls the rear steering mechanism through the hand-wheel 57 in front of his seat while he adjusts the planes 5, 6 and 9, 10 by the n'heelA Q. at the side of his seat. The inanner'iuu'vhtch the hand-wheel 57 is connected with the shafts 52 and is shown in Fig. (3, and is IS follows: To the upper and of the inner shaft- 52 is secured a. ring or segmental form ratchet, toothed member. or quadrant. 58. Beneath the latter on the upper end. of the hollow shaft 55 is loosely or rotatably mounted a hub 59 on the hand-wheel 57. hub are supported vertically on the hollow shaft by means of a collar 60 secured to the shaft 55. The hub 59 is keyed to or connected with the Fllllft by means of a pawl 61 on a lever 63' fulcrumed at 62 on a lag rising from the hub 59. The power-end of this: lever is provided with a thumb ieoe arrs'inperjl in proximity to the rim 0 the wheel so that when the latter is grasped for the purpose of rotating it the thumb of one hand may simultaneously operate IdGPIGSS the lever (33. The pawl-mid of the lever 63 held normally in engagjnent with the notches or teeth 58 by a spring fi lamed in in the side of the huh extending to The latter is provided with one through a cord .SllE sides of the rudder thumb of one hand may depress the lever sired pulley arrangement a recess in the top of thehuh as slu'n' Fig. 6, the outer end" of'this spring being arranged to bear against the lever to its pawl into engagement with thetoothed portion on top of the shaft or hollow shaft 55'is connected With-the huh 59 by means of a pin 65 mounted in e here the hell low shaft. or more bores 66 adapted to register with the end of the pin which is longitudinally movable in the hub.

At 67 the pin 65 is pivoted to the lower end of a lever 68 fulcrurned at 69 on the hub and having its power end arranged with respect to the rim in substantially the same manner as the lever 63. Hence the or running preferably along one side frame 2, 3 while another leg 0:5 seer 72 runs along the opposite tails of'leading the cord. and its the wheel 71 tot-he rudder are fied, these specific details being in for the purpose of this intention be varied in any desired manne rear end the runs 72 and]?! leading from the sides of the to opporepresented. only its lhc horizontal or steering Q II'MEQJTO; usual canvas covering being omit-aim plan view in order to disclose the parts underneath.

In the positions in which the parts of the controlling mechanism for the rear steering devices are shown in 6 the hand wheel 57 is connected with theshatt 52 and disconnected from the shaft without touching the small levers connected with this wheel its rotation will operate the horizontal steering plane i l. The rocking of the latter will also rocl; the rudder T, but the latters movement will. he merely edgewise and the shifting 0t its position in this manner will' not materially aiiect its function or steering hori'mntally. the rudder is to be operated or moved from side to side the operator will release tle lending arin formed by pawl oil-the lever no 'and'press down to o poslte lever to engage the with the hollow shaft. of: movement or Eithis g ivotal coinieetion being shown mounted on top-of the plane l l.
