Beit known that I, WILLIAM J. BRAD- at Killeen, in the county of Bell and'State. of` Texas, have invented certain new and useful Improvements in Airships, of which.

This invention comprehends'certain new and useful' improvements in1air ships'of the dirigible type, and the inventionhas for its A. further object of theinvention'is an-air shiprof this character' embodying a plurality'of cylindrical gas containers so con-.

:fgvnected together that the pressure will be at yall'times equalized. And" theinvention also has for. its' object a diri ible air ship which will b'e light, .strong an durable and capable of being easily steredftotheright; or

' fleft; or up` and down, the device embodying propellers at the front oft-the main or' body portion of theair ship, and a rudder at the y.rear of suclibody v being moved upwar ortion,v the Apropellers ly or downwardly so as..to cause the air ship to rise or descend,

and therudderat the stern being also-ca- 1 pable of being shifted to the right or to the leftand up. and down so as to assist in the steering operation. And the invention also has for 'its object, a machine of this charac` ter,- all of the parts of which including the driving means may be under the control of.,v

-' one driver.

ith these and otherobjccts in viewv as Awillmore fully appear as the description proceeds, the inventionconsists in certain constructions,:arrangements 'and combinations of the paits that I- shall hereinafter fully describe 'and claim.

For a full understanding of .the invention, reference is to bev had to the' following description and"accornpany1ng drawings in' which: Figure 1 isa perspectiveview of a flying machine Aor air st np constructed inaccor ance with my invention; Fig. 2- is a top plan view of the body portion; Fig. 3 is a titansverse sectional View; and, Fig. is a longitudinal view` illustrating the-means 'oradjusting the propeller shafts.

Corresponding and like partsare referred to in' the following description and indicated in all the views of the accompanying.

" and over correspo drawings by the same reference characters.

The main or body portion of my improved air ship embodies two cylindrical containers 1 that are ranged alongsideof each other with a space betweenior thecar to support the motor and steering apparatusl which are supported thereon refera'bly' below the ter of gravityofft 'e` containers so as' to assist in maintaining the4 stability' of the apparatus.' The details ofjtl 1'e=car are not herein shown. as they Patented J an, 1911.

present invention; Tliejcontainer's-1' are preferably tapering alti their bow or forward ends asindicated at 1* 2 designates the propellerafshafts .-.In thel pre'sent instance, these are 'twofjn number. .and theyv extend longitndinallyf- Projecting beyond the. forward n cylindrical containers ulfafnd."'being provided at their'forward endsgwithfprope lersSv and 4. whichare arranged in opposite directions. 'The rear ends'ofthe propeller shafts 2 are` jonrnaled" in vbearing I brackets `5 that are preferablyisecured to the front and intermediate* ofthev frames. 6 serving to strengthen the.'structure. There is'yalso a rear frame' designated 7. 'These'jfrontconnecting frames 6 and rear Aconneetin frame 7 are preferably strengthened by ia onal braces 8 as clearly'illnstrated in the wany desired way. In vfthe present lembodiment of the invention, they are rotated by means of belts 9 passedover 'p11'lleys10 secured' to the' rear extremities ofthe 1shafts j riding. plle'yfs''ll secured on the shafts ofthe motor-12 whichjmay be Aof any 'desired construction or types. In or,

".The for,

ward'seetions of fthe-'propellerv shafts 2 are .connected together by a cross-rod 15 andare' also connected by-llinks 16 to the cranks 17 of a transversely extending'shaft 18. This crank shaft lis jonrnaled'to rotate about its longitudinal-axi'sffas indicated inthe draw-- ing, and 'carries at 'an' intermediate-point, a

By swinging the hand lever 22 it is clear that the propellers 3 and Il will be inclined upwardly thereby causing the air shipY to ascend as it is propelled in a forward directlon, and a reverse movement of the hand. lever 22 will cause the Propellers 3 and 4 to drop so as to impart a downwardly inclined movement of the air ship. The rear A rudder of the air ship is composed of two arrange 'horizontal and the other vertical as` shown; .The. two. planes 23 -and 21l-are together hingedly connected' to the rear of' the machinelas vindicated at' 25 so thatthe entire ruddermay b'swun horizontally or. vertically. In order to e ect the up andA down movement ofthe rudder, the plane 24 has 'connected to it -at opposite sides of the plane 23 .cords or cables '26- which extend 25 through openings in'the rear frame of the A bodyfportionfof the air ship. and pass around .tand are securedlto an actuating wheel 27,
