CHARLES FRANCIS SMITH, 0F WESTFIELI), NEW YORK.v

AEROPLANE.

Application led May 29,

T0 all whom 'it may concern.

Be it known that I, CHARLES FRANCIS SMITH, a citizen of the United States, residing at "Westfield, in the county of Chautauqua and State of New York, have invented certain new and useful improvements Iin Aleroplanes, of which the following is a specification, reference being had therein to l the accompanying drawing.

rlhis invention relates to improvements` in aeroplanes, and has for its object to pro- .vide an improved machine of this character that will be capable of direct vertical ascension.

The invention, with other objects and advantages thereof, and the particular construction, combinations and arrangements of parts comprising the same, will be under- `stood from the following detail description when considered in connection with the accompanying drawings, forming part hereof, and illustrating one embodiment of the invention.

ln the drawings:

Figure 1 is a side'elevation of an aeroplane constructed in accordance with the present invention.

Fig, 2 is a vertical section of the main portion of the machine.

Fig. 3 is a detail plan View of one of the planes.

Fig. 4L is a detail transverse section of one ofthe planes.

Fig. 5 is a detail section of one ofjthc piston members ofthe air forcing means.

The invention comprehends an aeroplane having a vertically extending tubular body part, a pair of circular planes mounted on `said tubular body part to extend transversely thereof around the same and to revolve thereabout, power means for driving the planes in opposite directions, and air forcing means associated with and operated by the revolving planes for drawing air from the upper side of the planes and forcing the same downwardly through the tubular body part to the under side of the machine below the planes, in combination with means for propelling the machine horizontally, the propulsion effort developed by the pressure of the air expelled vdownwardly from the underside of the machine coupled with the rarefactiou of the air above the planes being suliicient to lift and sustain the Vvpart 1.

machine, enabling the same to rise vertically.' More particularly the invention contemplates a machine of this character having planes of inverted conical shape or ofdished formation with the dished side disposed upwardly, and air forcing and `propulsion means associated with each plane and comprising an annular pump chamber on the plane located centrally at n the upper side thereof, and a reciprocating piston in each pump chamber, the pistons being `coupled to the planes to rotate therewith while permitting reciprocatory movement of the pistons relative to the planes, an engine for driving each plane, a cam way for each piston, and

rollers journaled on the tubular body part .and engaging the cam ways of the piston4 to alternately reciprocate the pistons.

While a specific embodiment of the invention is illustrated in the drawings, it will of course be understood thatl changes and variations may be made in the particular construction shown, and the invention embodied in other forms, as will appeal to those skilled in the art and falling 1within the scope of the appended claims, without departing from the spiritof the invention.

Referring to 'a detail-description of the particular embodiment ofthe invention in the drawings, l designates the tubular body part shown as of cylindrical form with yan ,upper dome like end part 1a and being open lat its lower end 1b.

-line and dished with the dished side facing upwardly, the same being preferably, as

shown, of inverted conical form, said planes having hub portions 2a, 3a, engaging suitable anti-friction bearings et on the tubular body 5 "and V6. designate engines which may be of any of the conventional types of internal combustion engine, for driving the planes 2, 3. |The

engines

5 and 6, which aresuit-ably mounted on the tubular body part 1, preferably, as shown, at opposite Sides thereof, have driving shafts 7, 8, on

which are bevel pinions 9, 10, which mesh with bevel pinions, 11, 12, on the hub-portions 2a, 3a of the revolving `planes2, 3.

Associated ywith each of the revolving planes 2, 3, is air forcing means, said means annular wall extending from the outer sidev wall 16 to the periphery ot the plane and forming with said side wall andy a portion of the plane an air chamber 162. The tubular body part 1 is provided with rings of ports 17, 1S, and the inner walls 15 ot the pump chambers 13 have lowerlport'ions surrounding the rings ot ports 17, 13, of the tubular body part 1 and oliset outwardly tromthe tubular body part, and each provided with a ring ot ports 19. The pistons le are each provided with a series of ports 14t1 withV inwardly opening valves 141b controlling the same so that upon the up stroke of the pistons, the valves 14h will open and air will be drawn into the pump chambers 13, and on the downward stroke of the pistons the valves la thereof will close and the air in the pump chambers 13 will be forced therefrom through the ports 19, 17, 13, into the interior of the tubular body part 1 and downwardly 'through the same out ot' the lower end 1h thereof to the underside of the machine below the planes. rlhe pistons 14C are coupled to the planes 2, 3, to rotate therewith and provide tor reciprocatory movenient of the pistons relative to the planes by pins 20 on the planes 2, 3, engaging openings 21 in the pistons 111, suitable packing, not shown, being provided for the openings 21. with the planes 2, 3, to be :alternately operated thereby. Each pump piston is provided` with an annular part 22 which has a cam groove or way 23, that is engaged by pairsy of rollers 24 journaled1 on transverse( rods 25 inedly secured to the body part 1. The cam grooves or ways 23 have oppositely disposed elevated portions 23EL and intermediate depressions 23h, said cam grooves or ways being relatively arranged so that the pump pistons 141 will be alternately operated by the revolving planes, 2, 3.

Fixedly secured to the body part 1 between the planes 2, 3, is a car 26, the length oit the car being shown substantially equal the diameter of the planesq the car 26 being arranged with the tubular body part 1 eX- l ending centrally ot the ends of the car. at the 'forward end oit the car 26 is mounted a propeller 27 for propelling the machine horizontally, said propeller 27 being shown :is the conventional form ot aeroplane propeller. The propeller 2? is driven by a suitable interna-l combustion engine (not shown)` in accorda-nce with the common practice. 23 ignates a laterally swinging` steeringV vane mounted on the other end of the car lhe pump pistons 1K4. are connected 26 and having suitable cont-rol means not shown. The machine may be provided with a landing chassis 29 of any suitable construction.

rlhe tubular body part 1, the revolving plane 23, andthe' other parts of the machine are constructed of any suitable material sufficiently light and possessing the requisite strength.

ln the operation of the machine air will be drawn in by the air forcing means from the upper side of the planes 2, 3, and' forced downwardly through the tubular body part 1 to the under side of .the machine, the propelling power developed by the pressure of air expelled below the under side ot the machine and planes, with thel ra-.retaction produced at the upper side of the planes, being sutiticient to litt the machine vertically;
