Figure 12 is a detailof the valve arrangement used in the device of Figure 11 Referring to Figure 1, a light reflecting' silhouette II] in the shape of aplan view'of an air plane refiects sunlight (indicated by beam I2) coming through window 1.3, and projects the reflected rays ll upon an irregular reflecting sur face of ceiling [5 to form airplane image it, having the shape or silhouette It. Image it is caused to fly on ceiling IE or on walls iii; the flight being controlled by tilting 'silhouetteilfi to change the angle of incidence betweenbea'm I-2 and silhouette 10. To this end, silhouette ii! is mounted so that its nose may be tilted up or down, and its wings may bedipped to one side or the other to give image It the appearance of flying; Referring to Figures 2 and 5, this sil houette is mounted on a spindle l la about which the silhouette isgrotata'ble in a planeperpendicular to the spindle axis u. The spimue i w, morn ing thesilhouette, is sornoun'ted as to be capable itself of rocking in all directions with respect'to thefvertical. Thus the miniature airplane may is positioned at the front end ofthe' silhouette; thus providing a constant force; which tends always to tip the nose or the silhouette down wardly. As w'illbe more fully eiqolained hereinafter, means are provided to'retard the tllgl' ifi movement of the silhouette and so to retard the rate at whichsilhouette Ill tilts; and the rate at which image i6 'move's, thus creating the illusion of a flyingp'lane.

h To obtain the effect of steering "the movingimage I6; silhouette [0 may he turned about age I I, and as the silhouette is so turned; the weight; of course, turns with it and so continually tends to-tip the nose of the silhouette downwardly; no

matter at what degree of 'aai'muth the silhouette points. Thus-by manually silhouette 10} aboutaids "H the directionin ii-sage Hi 3 points is changed, and the planes image always flies forwardly. The silhouette Ill (Figure 2) is turned about axis H by manually turning steering disc 2|, which is rotatable through 360.

The silhouette l!) in the embodiment of Figure 2 comprises a metal stamping having a regular reflecting surface [4. Referring to Figure 4, the stamping and its supporting spindle I in are supported upon upright post 20 secured to a base |9. Rotatable about post 26 is the steering disc 2| carrying steering pin 22, passing through a slot 23 in plane Iii. Rotation of steering disc 2| about post 20 moves pin 22 and rotates plane I to change the degree of azimuth at which the plane points. Figure 2 shows the plane pointing to the left; whereas Figure 3 shows it turned through 180.

' Referring to Figure 5, spindle Ha supporting plane I0 extends upwardly from a movable base 24. Plane ||l carries bushing 21 which receives spindle ||a, holds the plane normal to axis H, and facilitates free turning of the plane about axis Bushing 27: is staked to plane l5 and, as shown in Figure 5, the lower end of the bushing is turned over as at 21a to provide a thrust bearing which runs on surface 25 of base 24.

Bushing 2'! passes centrally through the body of the silhouette m, so that turning of silhouette |0 about spindle ||a merely turns image IS on the ceiling to change the direction of its flight,

and does not give the impression of an unnatural or violent movement of the plane.

The outer annular surface of bushing 21 receives a removable colored transparent disc 29 which rests on top of surface l4 and serves to give the central part of image H3 an identifying color. The disc 29 is removable so that it may be replaced by discs of other colors.

Referring to Figure 5, the mechanism by which spindle Ha is mounted to move plane H] to give image I5 realistic flight travel will be described. Base 24 has a lower hemispherically shaped part 25, which sets in a spherically shaped cup 30 in the top of post 25. This construction provides for all directions and angles of rocking movement of base 24 in cup 52, and so of plane Iii which, as above described, is supported on the base. Thus the flying image may be guided and positioned as desired.

The plane-supporting base 24 is floated in cup 30 upon a pool of viscous liquid 3| that provides a fluid-friction-retarding force on base 24, that is the liquid provides viscous damping'of the movement of base 24. The liquid permits only slow rocking of base 24 in the cup under the influence of weight 34, and resists any tendency of base 24 to rotate about a vertical axis as the silhouette is rotated to guide the flying image.

Also, the fluid-friction action of fluid 3| holds the plane in any position of lateral tipping (wing dip) in which it may be while permitting continuous downward tipping of the nose. The liquid 3| may be a material such as heavy grease, or preferably a polymerized hydrocarbon of a straight-chain structure, such as Vistanex #8, sold by Advance Solvents and Chemical Corporation, 245 Fifth Avenue, New York, New York. A viscous materia1 which does not change its viscosity appreciably in temperature ranges from 60-130" F. is preferable.

Movement of base 24 in cup 3%! (referring to Figures 2 and 4) is caused by weight 34, which in effect applies to axis H a force component normal to the axis causing it to rock base 24 in the direction of the weight. Weight 34 is in fact a nut which threads on a nose portion 32 extending forwardly from the plane and having opposing serrated edges 33 cut to provide male threads for the nut 34. Nut 34 always overbalances the weight of the tail portion of the plane, but as the nut is moved forwardly on the nose, its leverage to rock base 24 is increased and the plane will tilt faster, thus making the image fly faster over the ceiling.

Movement of base 24 by weight 34, therefore, causes axis II to move with respect to a vertical axis XX. The movement is such as continuously to change the angular position of axis H with respect to the vertical axis X-X.

Since axis H can rock in any direction about its effective pivot point, any desired angle of incidence is obtainable within the limits of motion of the plane, and the plane silhouette may project the image l6 to any part of the room. In the Figure 2 embodiment, the plane silhouette can be tilted 30 in any direction from the horizontal.

Reviewing the functioning of the parts: since axis is always rocked in a direction determined by the azimuth position of weight 34 about vertical axis X-X,,manually changing the position of weight 34 changes the direction of flight of image I6 as desired. Thus, by merely turning steering disc 2|, which through pin 22 turns silhouette ID on spindle Ila, the direction of travel of the image on the ceiling'may be changed at will. Because liquid 3| so tightly holds base 24, turning of plane ID on spindle 'l |a does not move base 24 and does not cause any motion of image |6 other than to change its direction of flight.

The radius of cup 30 is preferably larger than that of spherical surface 25 of base 24, so that cup 30 acts as a reservoir to hold viscous material 3| between cup 3|) and base 24. Spherical surface 25, in effect, floats in the viscous liquid, and as the surface rocks in the liquid, the liquid keeps the surface coated, but the rim of cup 30 extending outwardly from surface 25 does not wipe the liquid from the surface, and so the liquid does not flow from the cup down the sides of post 20.

Annular lip 24a serves to prevent the viscous. sticky, liquid 3| from flowing onto surface 26, and so prevents the liquid from interfering with free turning of plane In about spindle Ha. But if material interfering with free turning of plane |0 does get onto bushing 21 or onto surface 25, then the parts are cleaned by lifting plane it) off spindle Ha.

Referring to Figure 5, base 24 is so constructed that in supporting plane II) it holds the geometric center of plane |0 approximately at the point A approximately at the center of hemispherical surface 25. To this end, supporting surface 26 and axis II are made to intersect approximately at point A. Because of the spherical conformation of part 25, rocking of base 24 in cup 30 does not laterally shift the point A of base 24; Therefore, since the point A, about which the base 24 must rock is centrally located with respect to the wings, and since weight 34 is symmetrically disposed with respect to the wings, lateral tipping of the plane does not shift theweight of the plane laterally, and so imparts no force to base 24 to rock it sideways in liquid 3|. Thus, however the plane In is laterally tipped, weight 34 always acts to rock axis forwardly without changing the lateral slope of plane l0, and causes image Hi to fly forwardly without any lateral component of motion.

This same eife'ct'of producing sideward movement of the plane,- in addition to its forward movement; may-be obtained in the Figure 2 embodiment by mounting silhouette Hi above the pointA- about which base 24 rocks.

Referring to Figure 8, another embodiment is shownfo'r supporting spindle Ila about which the plane silhouette l0 turns. In this embodi ment. spindle Ha is suitably mounted onthe' end of acircular piece of material 5|,- supported from base- I9. I teristic's which are'that of a solid viscous inaterial havifig low resilieno'y and bendable slowly under a'force applied normal to axis 1 I of spindle Ha; Support 5| shown being bent to the left under the influence of weight 34. Because-of the nature of the material, it slowly yields and bends under the influence of the force of the weight and so rock's axis H in any direction, as described in connection with the modifications of Figures 2 and 7. The material of support 5l may be polymerized hydrocarbons of straight chain structure of' high molecular-weight sold under the trade name Vistanexbythe above-'mentionedAd vance Solvents and Chemical- Corporation.

The material 'olfjsup'poit- 5i rnolded'to have a basepdrtiohii overwhi'ch an annul'arclainping support 53 extends to hold base portion 52 611" a post 530. suitably secured to and-supported from base l9.-. Post 53d also serves as the shaft for steering disc 2| carrying steering" pin 22 asde= scribed in connectionivith Figure 2.

This embodiment has the advantage of sim' plifying-the construction by eliminating liquid material 3| used in theFi'gures 2 and? embodiments. The fact that the'center of rotation or silhouette In is spaced considerably above the effective pivot fpoint about which spindle I la moves (namely; the point of connection of mate by a light spring 54 s'ecured at one end to a'post 55fextendin'g upwardly-from steeringdisc 2!.

51, which extends upwardly from spindle Hit. Post 55 is located diametrically opposite steering post 22:50 that the nose of the plane always points at post 55. Thus, the action of spring 56 applies a force to axis II in a direction to cause the plane to tilt'in the-directionofpost '55.

If desired, a turnbuckle arrangement (not shown)" may beprovided. to adjust the spring tension of spring 54; and so to provide means'for adjusting the speed or movement of image IS on the ceiling Because the pun-or spring 58 on rod sii aiweys directed toward post 55, when axis II is tilted laterallyout of the vertical plane containing post s 7 55; the spring' pull not only moves the 'plane'nos'e l tion cau'ses the'image-to fly in 'a. curved tours; v

rather than a' stfai'g-ht course, and this the a iteristic may be put to advantage by makingihore Material 5| is picked for its charac-i- Spring 54 at its other end is connected to a'rod v difflcultthe steering of image l6 over a desired course, thereby adding to the interest of a game involving skill in flying the image over the ceiling.

Referring to Figure 10, another embodiment of the invention is shown in which a magnetic force is utilized in place of the gravity force supplied by weight 34. In this modification, the lower end M of shaft il is formed of iron. Magnet 49 having north and south magnetic poles 50, is mounted on steering pin 22, which passes through slot 23 as in the Figure 2 embodiment. The magnet attracts the iron part M of shaft 4| and exerts a force upon it pulling it toward the magnet. Plane silhouette i is balanced so that its center of gravity is at the point where it passes through axis Thus, pull of magnet 49 on shaft part 44 causes the plane to move in the direction in which the plane is pointed by steering pin 22. By turning the steering disc 2|, the direction of the travel of image [6 is changed at will. But because When the plane is tilted laterally, the pull of the magnet on part 44 is not aligned with vertical axis X -X, theforce exerted by the magnet tends to give shaft 4| an additional lateral component of motion which adds to the difliculty of steering the plane.

Referring now to Figure 11, in this embodiment spindle ||a is mounted on a post 60-which in turn is secured to a support 6|. Support 6| in turn is mounted in such manner as to tilt in any direction. To this end, support 6| is mounted on three legs 62a, 62b and 620. The points of connection 63 between the legs and support 6| are made flexible. The legs are respectively flexibly secured to

pistons

64a, 64b and 640, operating in piston chambers 65a, 65b and 650. Piston chambers 65a, 65b and 650 are connected by

passages

66a, 66b and 660 to a valve chamber 61 (Figure 12) in which is mounted a rotatable valve 68 having connected

passages

69a, 69b and 690. Valve 68 is rotatable in valve chamber 61 by knob H3 extending above the valve chamber to adjust the alignment of

passages

69a, 69b and 690 with

passages

66a, 66b and 66c, respectively.

Piston chambers 65a, 65b and 650,

passages

66a, 66b and 660, and the passages in valve 68 are filled with liquid, and rotational adjustment of the valve 68 varies the freedom of flow of liquid between the piston chambers.

Applying a force normal to axis I causes

pistons

64a, 64b and 64.0 to rise and fall, their motion, however, being viscous damped by the controlled flow of liquid from the falling piston or pistons to the rising pistons or piston, thereby tilting axis II in the manner described in connection with the Figure 2 embodiment. By adjusting the position of valve 68 by knob 70, the speed of image l produced by axis movement is adjustable.

As in the Figure 2 embodiment, an annular steering device 2|a is provided carrying steering pin 22, which serves to steer the plane and change the direction of the application of the silhouette-operating force. The operating force may be obtained by gravity as in the Figure 2 embodiment, or by magnet as in the Figure embodiment, or by a spring as in the Figure 9 embodiment.

.It is to be understood that in place of a reflecting silhouette H), the spindle I la may be enlarged to contain a small battery and'lamp that projects a beam of light onto the ceiling, and that by providing a suitable image-controlling film with the lamp, an image may be cast onto the ceiling,

Also in place of the reflecting silhouette a light wood plane (for example balsa wood) may be mounted extending upwardly from the sleeve 21. A rod mounted close to the sleeve 21 would carry the Weight 34, and a rod extending in the opposite direction would cooperate with the steering pin. to turn the rod carrying the balsa wood plane. Thus. the'weight 34 would drive the base 24 "and the'plane, and the steering pin would be used to steer the plane in its flight. The balsa wood plane may be used to cast a moving shadow or may be moved around to simulate the flight of an actual plane.

As many embodiments might be made of the present invention and as many changes might be made in the embodiment disclosed herein, it is to be understood that the foregoing description is to be interpreted as illustrative only and not in a limiting sense.
