PAUL E. KLOPSTEG,-OF CHICAGO, IL -InoIs, essrenon TO CENTRAL scrimtr nIocom PAINY, OF CHICAGO, ILLINOIS, A oonroRATIoN on ILLINOIS Boron I'RoP LLEin'errAnATUs 4 Application filed May 11,

The principal object of this invention is to provide apparatus in which the basic features of the so-called'Flettner rotor ship,

will be represented, and will, in operation, 5 demonstrate the application of forces by which such a ship is propelled.

In the drawings Fig. lis a side elevation of the preferred embodiment of the apparatus, parts of the track being broken away;

Fig. 2 is a plan view of the apparatus shown in Fig. 1 and Fig. 3 is a transverse sectional view taken web 15 ofthe car frame 10 is a mast, or

pillar 16, made of brass tubing threaded externally at 17 to receive nuts 18 by which 30 it is clamped to the web 15. i

The upper ends of the pillars are connected by a cross arm 19 secured in place by screws 20 threaded into the upper ends of the pillars. V The cross piece 19 and the web 15 are provided with pivot bearings 21 for the shaft 22 of the rotor 23. The shaft is made of steel with the end sockets hardened to cooperate with the pivot bearings. The rotor 23 is composed of a length of brass tubing soldered at its endsto circular disks 24 which, in turn, are soldered to the shaft 22. The surface of the rotor is roughened in any suitable manner, as by means of a knurling tool, or broach.

The upper end of the shaft 22 is provided with a thumb wheel 25 between which and the upper disk 24 there is a short drum section 26 upon which a cord 27 maybe wound after being made fastto a pin 28; The track comprises a channel bar 29 with be accuratelyileveledn 1929. "serial No. 362,346.

the fianges=29 turned up, and theiredges milled' toa suitable curvature.- Front and About" one-quarterthe length of the bar from veachvend there'is fitted'a base casting 30 having lateral arms 31 equipped with leveling screws 32 by which the track: can

A- frame 33 rises from each end'offthe; beam29 and is'equipped with buffers comprisingpairs of phosphor bronze springs-84 lvlng close together except at their free ends where-they are spreadfapart, substantially as indicated at 35, to facilitate the entry of a bar 36eXtending across each end of the car 2 frame 10, and projecting slightly beyond its sides, as best seen in Fig. 2.

When it is desired to make a demonstra tion the apparatus is set up substantially as illustrated in the drawings, the car is'held against movement, and the cord 27 given a vigorous pull, spinning the rotor after the manner of a top, and it has suflicient properties of a fiy-wheel to continue in rapid rotation for a suitableperiod. r

A blast of air is then delivered against the rotor; for example, as by placing a'fanin the position shown at 37, in Fig.2. Assuming that the rotor is spinning in a counter clockwise direction, it will be apparentthat, due to the roughened surface, a considerable amount of air will be carried around with it. Hence, the velocity of the air particles are greater at A than at B and the pressure at B will, therefore, be greater than at A, and the car will be propelled to the left in Fig. 2.
