siennes.

l' Angeles, in the county of Los Angeles and Stateof California, have'invented a new and useful Air-Ship, of which-the following is the'specifcation.

This invention relates to air ships and one of the main objects of the invention is to provide an air ship havinga greater buoyancy than those rovided with flat surface aeroplanes, where y the ship is adapted to navigate in astrong wind. One or more stantially horizontal plane, and to the outer surface of the drums spiral wings are attached, which, as the cylinders revolve, yscrew The rotating wind striking the conveX- sides 'of the cylinder.'. Thelatter action serves to equalize the up and down pressures.

Vertical and horizontal rudders are' ar-l ranged inside of the `drums with the intention that the steering will be greatly facilitated. yAccommodations for the vpassengers are provided in the 'interior of the drums and thus greater safety is afforded-them, not

only when the ship is traveling, but-also in ali'ghting. This is by reason of the drums revolving in opposite directions which reverse movement gives an automatic balance sengers from the elements. i As it is expectedv that greater buoyancy will be obtained by,

this construction it is possible to use heavier and more substantial material than inV air ships which depend. for their-buoyancy on flat aero-planes, and are thus of less buoyancy. Thebuoyancy of this cylindrical construction is increased by reason of the inner.

faces of the upper halves of ythecylinders acting as aero-planes, and also the outer suri faces of their lower halves acting as aero-` lanes.- Buoyancy 'is further afforded by theV orwar'd rudder which is mounted in the forward cylinder and pivoted to swing in a vertical plane. .y

Specification of Letters Patent.

These platforms also act as aero-planes and thereby further increase the buoyancy. An air ship is thus produced having a great aero-plane surface arranged in the most condensed manner. Its supporting buoyancy should be much more than the di-rigible balloon or any form of lat surface aero-plane. Referring to the drawings z-Figure 1 is a vertical section Ytaken longitudinally through the air ship. Fig. 2 is a plan View of the Patented Nov. 9, 1909..

Economy and lutility are obtained by the. luse of platforms swinging in the drums.

complete ship. Fig. 3 is a section on line The ship comprises a forward drum 1 adapted to rrotate in one direction, and van after drum 2 adapted to rotate in the opposite direction. Each drum` has on its surface a series of wings or blades 3, those on Fig. 4 is a section on line the forward 4drum l being inclined in one direction, and those on the after drum being inclined in the opposite direction, the inclination of both sets of wings being such that as the cylinders revolve in opposite directions the ship will be propelled forward.` Each drum is braced at each `end by cross arms 4 which extend to hubs4 5. Extending axially through both drums isa Shaft 6. In the forward drum 1, asleeve 7 is rotatably mounted on the shaft 6, and the hubs 5 of the forward drum 1. are attached to the sleeve/7. In the after drum 2, hubs are attached directly to the shaft 6.

In the forward drum a platform S is hung by arms 9 from hubs 10 on the sleeve 7. An engine v11 is mounted on the deck 8, and is connected by a chain 12 with a sprocket 1 3 on the sleeve 7 so thatv as the engine operates it rotates the sleeve 7, andas the drum 1. is rigid with the sleeve it is also'rotated.

In the after drum 2 a similar platform 1.-t is suspended-by arms 15 from hubs 1G on shaft 6 and an engine 17 is connected by a chain 18 with a sprocket 19 on shaft G so that as engine 17 operates it drives shaft (3 and rotates the after drum 2. The engines are so p-lacedand gea-red to their respective driven velements that the forward drum 1 and after drum 2 are driven in opposite directions.

Arms 20 extend from the forward hub 10 in the forward drum l, and support 'a for- I that by oper-ating steering wheel23, ythe rudder 21 may be adjusted to 4various angular positions. j i J 'In the after drum 2 a 'vertical rudder 24 is -pivoted to'thef'verticalarm 25 and vis operated by a cable 26 connected with the wheel l2?.-v The forward horizontal rudder 21 acts asjan aero-plane but itis intended primarily to act as a -rudder fto vary the horizontal elevations of `thef'air 'ship'. The rear .vertical -v rudder 24 is intended tp act in steering the vvair ship to port ornstarboard or` to hold it in a straight course. A pair of legs 2,8 are prov vided at the forward end and project down at'zthe after end of theship.. 32 is anauxilthe `cylinders which present the;aeroplane4 surface .should have closed walls enable them toact as' aeroplanes and that the fori' wardand rear ends of said cylinders should j be open to enable the airto pass into and out of said cylinders. Ior the saine reason it is 'essential that the space at the front and rear of the cylinder or ofthe plurality of cylinders should be clear and unobstructed so that the air can pass freely to or from the cylinders.i What I'claim is l. In an air ship, an elongated, horizontal cylinder havinfrclosed side walls and open ends,.spi'ral blades on the outer surface of the cylinder forming a revolving aeroplane, and means for rotating .the cylinder, the space at thefront and at therear of the cylinder being clear of obstructions to permit ofthe .passage of air through andv out of the cylinder. 2. In an air ship, a plurality of elongated, Ahorizontal vconcentric cylinders each having closed side walls and-open ends, spiral'blades on the outer surface of the cylinders, and means for rotating the cylinders in opposite 'direc'ztionsb thespace at the front and at the rearof the plurality of cylinders being clear of obstructions to permit of the passage of air through and out of the cylinders. 3.' In an air ship, a plurality of elongated, horizontal concentric cylinders each having closed side walls and open ends, spiral blades on the outer surface of the"'cylind ers, and ineans for rotating the cylinders in opposite directions, a shaft extending through both cylinders, arms securing one cylinder to said shaft. a sleeve on said shaftand arms securing, the other cylinder to said sleeve, the

space at the front end and at the rear of the plurality of cylinders being clear of obstructions-to permit of the passage of air through sleeve on the shaft, arms projecting from said sleeve and supporting the forward cylinder, arms projecting from said shaft and supporting the after cylinder, platforms suspended inside the cylinders, and engines on the platforms connected respectively with said sleeve and shaft for driving the saine.

lIn an air ship, a pluralityof cylinders, a'shaft extending through the cylinders, a sleeve on the shaft, arms projecting from .said -sleeve and supporting the forward cylinder, arms projecting from said shaft and supporting the after cylinder, platforms sus` pended inside the cylinders, and engines on the-platforms connected respectively with said sleeve and shaft for driving the saine, a horizontal rudder in the forward cylinder,

- anda vertical rudder in the after cylinder.

6. In an air ship, a plurality of cylinders, a shaftextending -through the cylinders, a sleeve on the shaft, arms projecting from said sleeve and supporting the forward cylinder, arms projecting from said shaft and supporting the after cylinder, platforms suspended inside the cylinders, and engines on Vthe platforms connected respectively with said sleeve and shaft for driving the saine, a horizontal rudder in the forward cylinder, and a vertical rudder in the after cylinder, and ,wheels near the platforms and con nected by cables with the respective rudders for adjusting the rudders. v

7. In an air ship, a plurality of cylinders, a shaft extending through the cylinders, a sleeve on the shaft, arms projecting from said sleeve and supporting the forward cylinder, arms projecting from said shaft and supporting the after cylinder, platforms suspended inside the cylinders, and engines on the platforms connected respectively with said sleeve and shaft for driving the saine,

a horizontal rudder in the forward cylinder, and a vertical rudder in the after cylinder. and legs in fr ont of the forward cylinder and aft of thev after cylinder.

.In testimony whereof, I have hereunto set my hand at Los Angeles, California. this 17 th day of August, 1908.'
