Application January 8, 1944, Serial No. 517,596

This invention relates to a kaleidoscoplc projector and concerns itself primarily with means for projecting a constantly varying or changing pattern on a screen and it is an object of this invention to provide such an apparatus which is 16 Claims.' (Cl. 88-24) responsive to sound air waves preferably emitted loud speaker especially during a musical program; during such musical program, the various patterns will substantially follow the tempo or rhythm of the music.

During the use of such an apparatus, many artistic and beautiful patterns may be formed or created and in the event that it is desired to obtain a copy or impression of such pattern or design, this may be done by Ishutting' off the radio or source of the sound air waves. The light will, of course be left on while the copy or impression is taken.

With these and other objects in view which will become apparent as the description proceeds, this invention comprises the novel structure and combinations of parts hereinafter described and more particularly pointed outand defined in the appended claims. i

Fig. 10 is an elevational View of the screen showing one form oi an image and taken upon the line lli-I 0 of Fig. 3.

In referring tothe drawings which illustrate an embodiment of this invention, there is shown a casing Il which is closed except as to its rear end which may be open or provided with an aperture for receiving the sound air waves from a radio loud speaker. The sound air waves entering the casing are adapted to operate ve dia.- phragms, i3, iii, i5, I6 and 28 (Figs. l and 3). The diaphragme i3 and 28 are designed to be operated always during the use of the apparatus while the diaphragms i4, I5 and i6 may at times not be all in operation depending upon the pitch of the sound air waves. In other words, they are designed to respond to the pitch of the sound air waves; thus one may respond to a low pitch, another to a medium pitch andthe other to a high pitch. Then there may be partial response from one or more and complete response from others. This variation in responsive action produces a mixture of colors that varies the color oi the pat tern or design as will later more fully appear.

The diaphragm i3 (Figs'l and 9) is connected to a bracket frame il having a base portion te resting upon the bottom of the casing ii. The diaphragm i3 is connected with a link i9 which in turn is connected to an arm or lever 2li plv otally mounted upon a bracket 2i rising from the base i8 and carrying a pawl 22 on its upper end for operating a ratchet wheel'2t which is held from reverse rotation by a holding pawl 24. The ratchet `wheel 23 is :East cna stub shaft 25 mounted in ball bearings 26 housed in the bracket frame il. The upper end of the shaft 25 carries a spider 2l which supports a ring 27a that carries a dished diaphragm 2t previously referred to and which is in the form of a tray. The tray contains objects 29, 3E, 3i, 32, 33, and 3e of various shapes and designs which may be made of light material such as paper, tinsel or Celluloid.

Rotation of the stub shaft 25 step by step by the ratchet wheel'23 will rotate the tray 28 and change the positions o the objects therein with respect to the rays of light that illuminate the objects as will later appear, while the vibrations imparted to the tray by the sound air waves will move the objects 29 to 34 relative to each other so 'that a continually changing or varying pattern or design with respect to the projected image will be produced.

Above the tray 28, there is a hood 36 which is supported over the tray by arms 38 which may extend from the bracket il. The hood 36 is provided with an opening 39 in its top for the exit of reflected rays from the objects in the tray, which rays pass thru the open top of the tray and the open bottom of the hood. Above the opening 39 in the hood, the hood is provided with a neck portion 36a in which are secured convex lenses 44a in spaced relation that tend to brighten and render more deinite the pattern that is projected.

Rays of diierently colored light are adapted to be thrown upon the objects 29 to 34 from the light units 4|, 42, and 43, each of which carries a light bulb 4U at its top. These units are spaced 120 degrees apart and are at an elevation for projecting light rays upon the objects. Each unit is of similar construction; that is they are alike except as otherwise noted so a description of one will generally apply to the others. A spherical light reiiecting member dla is positioned under the cover Mb of each light casing. Light rays will be reflected from the reectors ila in a downward direction and many will pass thru the condenser lenses 4&-44 which are mounted in cylindrical neck portions dic upon the lower ends of the light casings. These condenser lenses are plano-convex and are mounted in spaced relation and serve to illuminate strongly the objects in the tray.

The neck portions Mc of the light casings are provided with slots 45 between the lenses dii-Lid. The slot in the casing dl is adapted for receiving a red film disk 36; the slot in the casing i2 is designed to receive a yellow lm disk lil; and the slot in the casing d3 is adapted to receive a blue lm disk 138. Each color lm d6, 4l and i8 is carried by a similar lever i9 which is pivoted at its upper endl in an arm 50 extending from the frame bracket il. Each lever 49 has a foot 59a to which the color lms are attached in any suitable manner. Each lever i9 is connected by a strut or arm 5i with its respective diaphragmhi, l5 or i6 of the artificial light units.

The diaphragms lli, l5 and i6 should be of different strength, yieldability or size so that one will respond to sound air waves of low pitch; another to sound air waves of medium pitch andthe other to sound air waves of high pitch. As these diaphragms are iiexed by sound air waves, the levers 69 will be actuated in accordance with the pitch of such waves to move their respective films into the paths of the light rays passing thru the condenser lenses, which rays will illuminate strongly the objects 29 to 3d in the tray 28. The light units may be secured in position at the most advantageous angle by welding or in any other suitable manner.

From the strongly illuminated objects in tray 28 which have reecting surfaces, rays of light will be reflected upwardly thru the aperture 3Q in the hood 36 and pass thru the double convex lenses 35a which will strengthen the illumination cast upon an inclined mirror 52 suitably supported from which rays of light will be reflected upon the interior surface of a V-shaped light reector 53 which has an linterior angle of sixty degrees which creates a six sided kaleidoscopic design. The interior surfaces of the reector are preferably highly polished.

Rays of light will be reflected from the reector 53 (Figs. 1 and 4) and pass thru a pair f The image projected upon the screen 5l' may be of the design or pattern 5l shown in Fig. 10. But this design or pattern will constantly change or be varied due to the shimmering or movements of the objects 29 to 34 in the tray 28 caused by the vibrations imparted to such tray by the sound air waves emitted by the radio loud speaker l2. At the same time, the colors of the image projected will be changed in accordance with the pitch of the sound waves acting upon the diaphragms i4, l5 and i6. This change of pitch will especially be pronounced during a musical program on the radio when high, low and intermediate notes are uttered.

Thus thru a changing color scheme and the vibratory movement of the objects forming the basis of the projected image, the patterns or designs of the image are constantly changed in an interesting and fascinating manner.

The apparatus is readily adapted to home use by positioning the same with the open end toward a radio loud speaker. The lights i0 should, of course, be turned on when it is desired to use the apparatus. Thereafter the apparatus functions automatically; the sound air waves operating the diierent diaphragms for eiecting changes in color, design or pattern of the image projected while the reflected light rays project the dlierent patterns or designs.

In practice, it may be desirable to place the apparatus in a radio cabinet or the like or it can be positioned in any convenient location adjacent thereto. The screen upon which the kaleidoscopic pattern is projected will, of course, be located in a vreadily observable place. After a kaleidoscopic pattern has been projectedl the action of the sound waves which cause the objects to move and change their locations and cause the reflected light to change the color of the light reected from the objects will be instrumental in causing a continual change in the projected kaleidoscopic design that may be very fascinating to observe.

On account of the ease with which the objects `29 to 3d may be changed for diierent objects of scopic designs and in this way the apparatus may serve as a creator of new patterns or designs.

I am aware that many changes may be made and various details of construction may be varied without departing from the principles of this in- Vention so I do not propose limiting the patent that may be granted thereon otherwise than necessitated by the appended claims.
