Specification of Letters Patent.

Patented. June 8,1909.

Application filed October 16, 1308. Serial No. 453,013.

1 i112, drawing. 1

This invention relates to air ships, andthe primary object of; mg invention is the provision of positive an reliable means in con noction with an ai ship for freely supporting a gas or air bag relative to the steering and pro oiling mechanism, whereby the gas or air bag will be free to revolve in a horizontal plane irrespective of the direction or strata of an air current. J I I A further object of my invention is coprovide an air ship that will be equally balanced, rigid and safe for traveling or observation purposes. l

A. further object of this invention is to" utilize a revoluble, rigid or flexible body for to an air ship irrespective of carriage planes and propellers.

With t above and other. objects in view which will more readily appear'as the invention is better understood, the same consists in the novel construction, combination and arrangement of parts to be presently described and then specifically claimed.

In the drawings Figure 1 is an elevation of the air ship constructed in accordance withmy inventiompartly broken away'and partly in section, FigQZ is a plan of the carriage or basket thereof, Fig. 3 isa vertical cross sectional view of a portion of the air shi and Fig. 4 is a sectional view of a modifie. form of construction.

As heretofore stated, the present invention relates to that type ofaeronautical crafts,

known as air shi s either lighter or heavier than air, which i epends upon theconstruc: tion and use of thesame Y in carrying my invention into effect, I use a vertical stem 1 having the lower end thereof provided with a head 2, while the opposite end 3 is threaded'for a detachable The head 3 is provided with an annular race '5 for antifriction balls 6.

The stem 1 intermediate the ends thereof is provided witha fixed platform 7 having an annular ball race 8 for-anti friction balls ,9.

= Between the balls 6 and 9 is supported a rigid or flexible structure that is preferably oircu lar in plan and elliptical in elevation. As

shown in the drawings, this structure comprises two. disk-shaped members 10 having peripheral flanges 11. The members 10 are provided with central openings 12 connected y a vertical sleeve 13, which surrounds the stem 1. The interior of the members 10 and the exterior of the sleeve 13 are lined or coated, as at 14, to provide a non-leakable structure- The members win some in stances can .be made of a rigid, light and dubag. In either instance, the peripheral flanges 11 are provided with a fixed fan-tail rudder 15, this rudder keepin the direction of an air current by reason 0 the structure being mounted upon ball bearings between the latform 7 and the head 4. T e head 2 is rovided with an annular race for anti-friction balls 165, and revolubly mounted upon these balls is a carriage or basket 17,, ore'l'erably oblong in plan. The carriage or basket 17 is provlded with a central vertical sleeve 18 surrounding the lower part of the stem 1, and the upper end of this sleeve is cupped to accommodate anti-friction balls 19. These balls are adapted to bear against the stem 1 and are retained in place by a cap 20 threaded u on said stem. '0 will of course be understoo that this cap is placed upon the stem 1 prior to securing the platform 7 and the head 4 in position.

In the carriage or basket -17 is arranged a bearing 21 for propeller shafts 22 and a drive shaft 23, said propeller shafts being provided with gear wheels 24 adapted to mesh with a gear wheel 25 carried by the shaft 23. The shai ts 22- protrude from the end of the carriaga or basket 17 and areprovided with pro pcllers 26. 4

. The drive shaft 23 is driven by a motor 27 or similar source of power located in the carriage or basket 17. 1,

The carriage or basket 17 is provided with a bearing 28 and journaled in this bearing and the bearing 21 is a shaft 28* having a gear wheel 28* adapted to mesh with the lowermost-gear wheel 24. Upon the shaft 23 is mounted. a gear wheel 28 meshing with a'gear wheel 28, mounted upon ashalt 28 lower end of the shaft 31 is provided with a propeller wheel 32 for lifting and elevating on air ship irrespective of the overheed structure.

The lowermost propeller shaft 22 is prolonged and provided with a beveled gear Wheel 29 meshing with a beveled year wheel 29 mounted upon the upper end 01 8, vertical shaft 29 journaled in the corriagepr basket 17. The lower end oi the shaft 29" is pro vided with a propeller 29 adapted to eooperete with the propeller Wheel. 32.

In hi 4 of the drawings, I have illustrated smod' cation of my invention wherein the upper end of the stem 1 is provided with a fixed head 83 adapted to be secured, as by rivets 34 m; the bottom of a rigid or flexible structure. in this instance, the carriage or basket 17 will be free to rotate in a horizontalplane relative to the overhead structure.

While in the drawings forming a part of this application there are illustrated the preferred embodiments of my invention, 1t 1s obvious that the same can be varied or changed as to shape, proportion and manner carried by the upper end of said stein, suit overhead structure comprising the shaped members hev'ing adjoining perh lurul flanges, a rudder secured to the ll; 9 said structure, a carriage rovolubly mourned upon the head on the loner end oi said stein,

\ invent; w

structure comprising two rigid disks having eripherzil adjoining edges, u rudder carried liy said structure, 0. earrings revolubly ID on n ted upon the lower end oi stein, propellers revolubly supported b y said earrings, :1, rudder carried by said carriage, and means lovcated in suid carriage for imparting a rotary movement to said pro xellers.

3. In an air ship, a vertical stein, an ver-- head structure" revolubly-niountod on the upper portion of the stern, and comprising two disk-shaped members having adjoining peripheral flanges, a. rudder seonred thereto, a carriage revolubly-mounted on the lower portion of the stem, propellers carried by said carriage, means in the carriage for driving said propellers, and u nninually-operablerudder earned by the carriage.

In testimony whereof l; :iliix my signature in the presence of two witnesses.
