To all lwhom t may concern:

Be it known that I, ALEXANDER BENNETT, a citizen of the United States, residing at Buffalo, in the county of Erie' and State of New York, have invented certain new and useful Improvements in Flying Machines, of which the following is a specification.

This invention relates to airships or flying machines, and more particularly to that type of machine in which the usual lifting and sustaining planes are dispensed with.

The primary object of my invention is the production of an airship or flyingmachine which is capable of risin directly'from the ground in ayertical or su stantially vertical irection'; which. is capable of being sustained the air in a substantially fixed condition over a fixed position; and which may also be lowered without resorting to the usual gliding or forward lowering movements. p

A further object of my. invention is the provision of an airship orlfiying machinehaving elevating propellers in combination with housings for the same provided with adjustable members capable of being positioned to direct the airship or machine when in flightv to the right, to the left, or upwardly or downwardly, as may be` desired.

v A still further object of my invention is the provision 'of a' machine of this type hav ing a plurality of elevating propellers which are operated in unison and in connection with which means is rovided for controlling the amount of air isplaced thereby.

With thesey and other objects 1n view which will be apparent from the description to follow,l my invention consists in the novel features of construction and in the arrange ment and combination ofparts to be hereinafter described and more particularly pointed out in the subjoined clalms.

In the drawings f Fig. 1 is a side elevation of an airship or dying machine representatively embodying my invention. f.

Fig. 2 is aplan view of the same;

Fig. 3 is a detailed view of part of ,the mechanism for driving the elevating propellers. Y

Fig. e is a transverse section taken on line a--a, Fig. 2, looking in the direction of the arrow crossingsaid line.

p n 7 to 12are diagrammatic views show-v lng the adjustable members of the propeller Referencerbeing now had to the drawings in detail, corresponding numerals refer to corresponding parts in the several figures. The reference numeral 1 designates the car or body of the machine which will, ofv

course, be constructed of light material and may be of any desired form or outline. It is, however, preferably elongated and comprises an upper compartment 2 and a lower compartment 3, the upper compartment being adapted for passengers while in the lower compartment the engine. 4 is located'.

.In said compartment 3, preferably forwardf of the engine, the operator is to take his place so that he will havev a view forward through the lookout windows 5, which may be formed of light transparent materiaL y At the rear of the car 0r body is a driving propeller .6 which is loosely' mounted on a ropeller shaft 7 extending forwardly and being secured to the shaft of the engine 4. On the hub of the propeller, a clutch member 8 is formed. This clutch member is therefore loose on the shaft and rotates with said propeller. A clutch 9 is. feathered on said shaftso as to slide lengthwise thereon, :and suitable means for moving said clutch member 9 into-engagement with or out of engagement from the clutch member 8 is provided, said means comprising a rod 1,0 extending forwardly underneath the bottom or floor 11 of the car or body and having its rear end bent upwardly and forked tol straddle -the clutch member 9. At the frontr end of said rod an operating lever 12 is pivotally connected therewith, said lever being situated in close proximity to the operators seat 13.

At each side of the car or body 2, propeller housings are located, these housings being designated, res ectively, by the

numerals

14, 15, 16 and 1%, the housings 14; and

15 being at one side of the car or body while the

housings

16, ,17 are at 4the other side thereof. -One housing is therefore located at each side near the front end of the car or body and one at each side near the rear end thereof. v

These housings are'supported from the car or body in any suitable manner, but I have shown brackets 18 secured to the body and-extending therefrom and to each pair of brackets one of the housings is secured. Each of these housings comprises a cylindrical propeller-receiving section 19 having the lower end thereof enlarged with the outer surface thereof curved, as at 20, and on the curved enlarged lower end, a combined air deilector and balancing device 21 is placed, each defieotor and balancing device being in the form of an annulus 22y having its wall concavo-convex and formed to a circle whose axis is that of the curved enlarged lower end of the cylindrical propeller-receiving section 19. The annuli 22, which may be said to be parti-spherical in form taken in connection with the curved lower ends of the cylindrical section 19 of the propeller lhousings serve as directional means whereby the machine may be directed in its course through the air, and they also serve as balancing 'means whereby the equilibrium of the machine may be mainined. Each of the anuli is manually actuated and the means provided for this purpose is constructed and arranged as follows:

A spider 23 is secured in each annulus`22, and depending from the solid center 24 of each splder is a lrod 25 having a ball socket 26 at its lower end. A rod 27 extends inwardly from the socketed lower end of each rod 25, and each rod-27 is provided at its outer end with a ball 28 adapted to fit its mating socket 26 and with a ball socket 29 at its inner end. The rods 27 extending vinwardly from the two annuli at the rear of the car or body have their socketed inner ends arranged to receive balls 30 formed on the rear end of horizontally disposed rods 31 slidable in suitable ball-socketed guides 32 secured to the .floor or bottom of the car or body and provided at their front ends with balls 33 which fit into ball sockets 34 formed on the lower ends of operating levers 35.

The rods "2 7 secured to the socketed lower ends of the rods `25 depending from the annuli at the front end of the car or body have their socketed inner ends arranged to receive balls 36 formed on the lower ends of operating levers 37. The levers and 37 extend upwardly through the floor or bottom of the car or body and have spherical portions 38 between their ends which t in sockets 39 secured to the upper side of saidoor or bottom. It will be observed therefore that all points ofthe mechanism for operating the combined directional and lbalancing means are in the form of ball and socket joints, and

with a view to obtaining a freer action of this mechanism each of the rods 27 is guided in-a ball 40 fitted within a socket 41 secured to the sidewall or frame of the car or body beneath thefloor or bottom thereof.

While I have shown an operating lever for operating each deflector or annulus 22, provision may be made for otherwise operating the same.

Near the 'upper and lower ends of the cylindrical 4section 19 of each propeller l1ousing, spiders 42 are situated, through the solid central portions 43 of which a Erd peller shaft 44 is passed, each propellers aft being arranged axially within its housing and having a propeller 45 secured'thercto. Each propeller consists of an elongated hub 46 and wings 47 inclined to the axis of said hub and being co-extensive with said hub. Secured to the upper end of each propeller shaft is a bevel gear 48 adaptedvto be driven by suitable mechanism operated from the engine. For this purpose four transverse shafts 49 are provided, each having a bevel gear 50 at its outer end in mesh with the bevel gear 48 on one of the propeller shafts,

.and at the inner end of each shaft 49 a bevel gear 51 is secured. The transverse shafts 49 therefore extend inwardly from the propeller'shafts 44. The transverse shafts 49 associated with the front propellers and those associated with the rea-r pro 11ers have alined axes so that 4these shafts are paired and the bevel gears 51 at the inner ends thereof are arranged in opposition to each other. Each of the shafts 49 is jou-rnaled in

bearings

52, 53 secured, respectively, to the spider 42 of the associated prol[peller housing and to the top of the car or 54 designates a shaft arranged lengthwise above the topv of the car or-body andjournaledin bearings 55. Secured to the front end of the shaft 54 is a bevel gear 56 which is in mesh with the opposed bevel gears I51 at the inner ends of the front pair of transverse shafts 49, and a similar bevel gear 57 is secured to said shaft 54 and is in mesh with the oevel gearsl at the inner ends of the rear pair of'transverse shafts 49.

The shaft 54 extends rearwardly beyond the rear end of the car or projecting end thereof a sprocket wheel 58 is secured, around which and a sprocket wheel 59 on the 'propeller shaft 7 a sprocket chain 60 passes. The propellers are therefore rotated from the propeller shaft through means of the driving mechanism, last described. The air displaced downwardly by means of the propellers 45 is of course drawn through the propeller housings from the upper ends thereof. To govern the amount of air displaced I provide regulating means 61, preferably in the form of two semi-circular closure plates 62 having exbody, and to theextensions of each pair ofclosure plates coact.I These plates are secured to shafts 64 passing upwardly .into or through said'extensions 63, and thevco-acting edges.` of said extensions are provided with gear teeth 66. The extensions with the gear teeth thereon serve as gear segments which are integral with the closure plates and are so arranged -that when one of the shafts-64 is rotated the closure Vplate secured thereto is caused to swing, and by reason of the integralA gear segment thereon being in co-action with the gear segment on the other plate, corresponding movement is imparted to said plate.

. For the purpose of operating the closure plates, the shaft '64l secured -to one of each pair of closure/plates is provided with a bevel gear 67 at-its lower^ end, which is in mesh with a bevel gear 68 on a transverse shaft 69 extending into the car or body and being journaled 1n one of the walls or the frame of the car `or body and in a bracket 70 secured to the under side of the floor 71 which separates the upper compartment 2 'n from the lower compartment 3.

At the inner end of each shaft 69 a bevel gear 72 is secured. 73 designates a longitudinally-disposed shaft iournaled in bearings 74 secured to the floor 71, said shaft having bevel gears 75 secured thereto which vmesh with the bevelv gears 72 at the inner ends of the transverse shafts 69, one bevel gear 75 being provided for each bevel gear 72.

Secured to the longitudinally-disposed shaft 73 is an operating wheel 76 by means of which the shaft may be rotated in either direction, the movement of said shaft being imparted through the

shafts

69 and 64 to the closureplates 62 to swing the same outwardly or inwardly for the purpose of regulating the openings in the tops of the respective propeller housings.l In this manner the amount of airdisplaced downwardly by the propellersis regulated according to the ascending or descending movement desired for the machine.

In the diagrammatic views shown in Figs. 7 to 12, the directional means, which the annuli 22 andthe mechanism for operating said annuli constitute, is shown in different positions, and it is to be noted that owing to all joints, pivots and guides of this mechanism beingof ball and socket construction, each of the depending rods 25, positioned axially with respect to thexannulus to which it is secured, vmay 'be swung radially in any direction on the center or axis of said annulus, which the extended axis of said rod intersects. Therefore, the annuli may be moved on the lower ends of the cylindrical section of the propeller housings either forwardly, backwardly, laterally in veither direction, .or they may be inclined obliquely.l

the propellers.

moved forwardly so that the inner surfaces thereof at the rearl of the same are ex osed displaced downwar y by hen therefore the main or driving propeller 6 is inoperative and the elevating or lifting propellers 45 are in motion, the air displaced downwardly by the latter is brought into forcible contact with the rear delecting portions of the annuli and tend to move the'car in a rearward direc-tion, as indicated by the arrow 77 in Fig. 7.

to the air bein When the annuli are thus positioned with the propellers 45 rotating and the driving propeller 6 is reversed to cause rearward movement of the machine, the annuli assist in driving the machine in a rearward direction.

When positioning the annuli as shown in Fig. 8, in which they are adjusted rearwardly to expose the front portions of the inner surfaces thereof to the downwardly displaced air, they tend to drive the machine in a forward direction, as indicated by the arrow 78 in said figure, and when the propellers 45 are operated jointly with the driving"Y propeller 6, these annuli assist in.' 1mparting forward movementto the machine. In this position they thereforeincrease the velocityof the machine although they would naturally tend toplift the machine to a higher altitude.

In Fig. 9 the front annulus at the left of the machine and the rear annulus at the right of the machine are adjusted outwardly1 'while the remaining annuli are retained in vertical or normal positions. When therefore the driving propeller is operated andl the machine is driven in a forward direction, the elevating or side propellers cause the air displaced downwardly by the front propeller at the left of the machine to the inner portion of the inner surface of the corresponding annulus while the airv displaced downwardly by the rear propeller at the right` of the machine acts against the inner portion ofthe inner surface of the corresponding annulus. The downward displacement` of the air inthe front annulus at the right of the machine tends to move. the front of the machine in the direction indicated by the arrow 7 9 in said figure, while the air displaced by the propeller in the rear annulus at the right of the machine tends to move the rear of the machine in the direction of the ya'rrow 80 in said figure. It will be observed therefore that a reverse action is caused at the front and rear of the machine which enables the machine to be turne-d to the right in a very short radius.

In Fig. 10 the front annulus at the right of the machine and the rear annulus at the left o f the machine are adjusted laterally with a view of swingingthe rear end of -the machine in 'the direction of the arrow The annuli can therefore be adjusted to anyA machine in the direction of the arrow 82 in said figure, thus causing the machine to turn to the left.

flhe annuli may also be used as balancing means. The posltions ofthe annuli shown in Fig. 7 would tend to overcome the tendency of the machine dipping forwardly,

while the positions of the annuli shown 1n Fig. 8 would overcome the tendency of the machine tilting downwardly and rearwardly. In Figs. 11 and 12 the annuli are shown in positions tending to overcome wind resistance directed .in the direction of the arrows 83 and 84, respectively. Any tendency of the machine tipping laterally to the right would be overcome by adjusting the annuli at the left of the machine to the positions in which the front annulus at the left of the machine in Fig. 9 and the rear annulus at the left of the machine in Fig. 10 are shown, while the tendenc of the machine tipping to the left woul be overcome by tilting the annuli at the right of the machine to the positions in which the front annulus at the right of the machine in Fig. 10 andI the rear annulus at the right of the machine in Fig. 9 are shown.

I have therefore provided combined directional and balancing means ca able of being used for either purpose or or both purposes at the same time, due to the fact that each annulus is operated independently by a lever, such as 35, which is capable of being swung radially in any direction to swing any of the annuli in the desired direction.

desired combination of positions and may be retained in adjusted positions by suitable mechanism, such for example as a pedal 85 extending up through the floor or bottom of the car or body in front ofthe operators seat 13, said lpedal having operative connection with brake shoes 8'6 acting against the rods 27 to hold them in any adjusted position, the brake shoes being retained against said rods'by means of a. spring 87, the action of which is overcom upon depressing the pedal 85.

When starting on a flight, the clutch members of the main propeller 6 are disconnected, and the closure plates 62 yoperated to fully open the upper ends of the housings of the liftingpropellers. rotation of the' last-named propellers the machine is caused to ascend a vertical or substantially vertical plane, and when the desired height has been reached the closure plates 62 may be closed or partially closed, depending on the particular purpose in mind. The mlain propeller 6 is then brought into action and the machine driven ina forward drection. If the course is to be in astraight line and the altitude maintained, the closure plates are adjusted so that the amount of alr displaced downwardly is just Upon f downward displacement of air in the propeller housings. If the equilibrium of the machine `is disturbed the annuli 22 are operatedin the necessary directions to produce the combination of adjustments desired and the necessary counteracting effect. If a change in direction lis desired the annuli are operated accordingly. When it is desired to maintain the machin'in a substantially fixed position and at a desired altitude, the main propeller 6 is disconnected from the engine and the lifting propellers operated with the desired air displacement controlled b the closure plates 62, the amount of airdisplaced being exactly that required to sustain the machine. chine is therefore highly desirable for purposes of war, since it would be possible to drop bombs over any desired point, suitable provision of course being m'ade for this purpose, as sulicient space is provided within the car or body of thecar for storage purposes.
