Tonll wlinmfit-my cantera:

Be 'it known thatI, "JAMES B. Magnum, a citizen of the UnitedjStates, ,residin at Brooklyn, in the county of ',Kings and i tate of New York, have invented certain new and useful Im rovements in Flying-Machines; and I do veclare the following to be a full, clear, andexact description of the invention,

` such as will enable others skilled in the artto which it a'ppertainsv to make and use the same. v

This invention relates to flying machines and has for its object to produce a flying machine supported, propelled and guided by rotating a1r prope lers.

Another .object is to produce a device of this kind which vwill be. convenient and eliif cient in operation. To accomplish this is provided a lplurality of horizontally and vertically disposed cylinders having propeller blades at the mouth thereof whereby a partial vacuum isA formed in front of said propeller blades and the air is congested in the air cylinders'behind said blades.

Another object is to -provide such an arrangement of said horizontallyl and vertically disposed cylinders that air blasts generated by said cylinders contact each other in such a manner as to momentarily divert them from their directcourse of escape from their respective cylinders temporarily re'- ta-rding their progress thereby still further au o enting the compression and resistance .4 an kthus accelerating the. movement of the v and scope of the invention.

not vlimited to these las the.l details of constructionan'd` combination may be greatly varied without departing from the spirit In the annexed drawing forming a art of this specification' in which like rel erence characters refer to like parts thrpu hout the' several views and which are for i ustrative purposes and therefore not drawn to any i. particular scale, Figure lis a-front elevationj. Fig. 2 isa top plan vient;- Fig. 3 is a ln @1 i'tudinal sectional View. The mam features'of thelyelitically disppsed ope-mended .Cylnes 1 and thezhprzontallydisposed cylindersQ.

Qns of each of these is provided. ,011. .each VSide of thej longitudinal .central plane of4 the in achine and'they meet each other at right an- `gles as shown. Said cylinders are supported upon a' frame 3 having cross braces 4 and are supported by forward wheels 5 and a rear wheel 6, said wheels having spring connection as at 7 with the frame whereby the machine will not be jarred excessively or broken when it descends. said frame is provided a gasolene engine 8 or other source of power. The shaft 9 of said, engine is provided with a forward sprocket wheel 10 and a rear sprocket wheel 11. Clutches 12 and 13 serve to disconnect said sprockets from said shaft. The sprocket 10 is provided with a chain passing over the `upper sprocket 31 rotatably mounted upon the forward center shaft 14, suitably supported as at 16 and connected to laterally.ektending shafts 17 which are in turn geared to horizontally lying shafts 18 coaxial with the cylinders 2 and carrying at the forward end a propeller 19.

A 'sprocket chain connects the sprocket wheel 11 with the sprocket 20 upon the shaft 21 and the forward end of said shaft is con* nected byl means of the clutch 22 with the beveled-gears 23 intermeshing with the gears on the rear laterally extending shafts 24 having gears intermeshin with gears on the vertically extending sha ts 25 carrying the propellers 2G in the upper part of the cylinders 1.v

The rear end of the shaft 21 is provided with a beveled gear 27 intermeshing with the horizontal gear 28 in turn. inter-meshing with the beveled gear 29 upon the short shaft 30 carrying thc rear propeller 31. lThe short shaft 30 is carried kin a bearing support 32 rigidlysecured upon the rotatable vertical support 33 carrying the wheel 6. A wheel 34 upon said vertical sup )ort Sis adapted tol receive a belt or the llke 35 cbrln'ected to a.

clutch 38 is pr'ovi ed intermediate the ends of the shaft 21. A link and lever 39 and 4:0

lplaced in a convenient positionenables the operator to operate said clutch.

. The operation of the machine is a fols About midway of' lows :'-The gasolene engine is started as usual and any of the

propellers

19, 26 or 3'1 may be thrown in gear by means of the clutches 12, 13, Q2 and 38, thus causing the machine to move upwardly or downwardly or forwardly as desired. The steerings explained.

I claim as new and desire to-secure by U. S. Letters-Patent is In a machine of the character described, a pair of horizontally projecting cylinders, a

thereof arranged adjacent the outlets of the 15 horizontally projecting cylinders, fans jonrnaled in all of said cylinders, a mechanism I for operating said fans, the blast from said done by means of the wheel 37 as has been l fans 1n the vertical cylinders crossing that of the blast from the forwardly projecting Having thus described my invention, what i cylinders.l

In testimony whereof I have hereunto s et my hand in presence of two subscribing Wit nesses.
