This invention relates to decorative lighting. The object of the invention is the provisionof a method and apparatus for pro ducing novel lighting effects, adapted for theatres, ball rooms, display and other like purposes, and which include the production of a plurality of artistic moving images, spaced through the exhibition room and moving across the same along the ceiling, walls and floor thereof.
A further object of the invention is the provision of a method and apparatus of the character described, said apparatus comprising few and simple parts which operate easily by theimproved method to produce a desired novel lighting effect, said apparatus being relatively'cheap to construct, and practical and efficient to a high degree for the purposes described.
Other objects of this invention will in part be obvious and in part hereinafter pointed out.
"The invention accordingly consists in the features of construction, combinations of ele- 5 ments and arrangement of parts which will be exemplifiedin the construction hereinafter described, and of which the scope of application will be indicated in the following claims.
In the accompanying drawing, in which is shown one of the various possible illustrative embodiments of this invention,
Fig. 1 is a view showing the improved ary rangement of the apparatus for producing the novel lighting effects embodying the invention, parts being broken away to show the interior construction. The path of several projected beams of light and their corregrammatically Figs. 2 and 3 are fragmentary front and side elevational viewsrespectively of the lens portion ofa projecting lantern, arranged to produce a multi-colored, star-shaped design element, adapted to form the moving image, when projected on the reflecting chandelier; an
Fig. 4 is a View showing a modified form of the invention for producing images moving in opposite directions.
sponding reflected! images are shown dia Referring in detail to the drawing, the apparatus for producing the lighting effects embodying the invention, is seen to comprise a reflecting chandelier or crystal shower 10, adaptedto revolve about. a vertical axis, and one or more spaced, light-projecting lanterns 11, 12, suitably supported in relatively fixed J positions with respect to the chandelier.
To form a unitary structure of the apparatus, said lanterns and chandelier may be mounted ona suitably constructed supporting frame 13, as shown in Fig. 1. i
The chandelier 10 may be of any desired artistic shape, such as a ball, semi-spherical, or, as shown in Fig. 1, may comprise a canopy portion 10*, a neck 10 depending therefrom, and a. bulbous end portion 10, the" outer surface of said chandelier portions being provided with image reflecting members or-mirrors l4, artistically arranged, as, for example, in a plurality of rows.
For revolubly mounting the chandelier 10, there is provided suitable means, such as a base 15, firmly secured to the frame 13, and having a hanger member 16 adapted to carry the lower raceway portion 17 a of a horizontally disposed ball bearing 17, the chandelier 10 being supported from the upper; raceway portion 17 of said bearing by suspension means 18, suitably secured to the body of the chandelier.
A motor 20, connected to a suitable electric supply source (not shown), ismounted on the base 15 and is adapted, through suitable power transmitting means, such as a friction drive comprising a pulley 22 and disc 23, for rotating the chandelier, the pulley 22 being driven by the motor, and the disc 23 secured to the suspension means 18.
From the above description and the-drawing, it is apparent that the motor 20, when in operation, may be made to revolve the chandelier 10 on the bearing 17 at any desired speed. It is to be understood that suitable speed reducing means, when required, may be incorporated into the said power transmltting means for the chandelier drive.
The lanterns 11, 12, may be of any suitable construction and, as seen from Figs. 1 and 4, veach'comprises a casing 30, having a front to give satisfactory results. Said casing has mounted therein a suitable light source, preferably in the form of an electric lamp 32, connected to the conductor wires 21, said lamp 7 beingpreferably provided with adjustable means 33 for spacing the lamp 32 with respect to the lens to focus the projected light rays, and areflector 34,-positioned in the rear end of the casing for directing the light rays to the lens in the manner well understood.
Each lantern is mounted on a. yoke 35, swivelly fastened to a depending arm 13" of the frame 13 and pivotally secured to the casing to permit directing thelightto any of the portions of the chandelier. To produce the novel lighting efliects wit the apparatus, the light rays projected from the lens of the lanterns 11, 12, are adjusted to impinge upon the mirrors 14, then the lamps V In Fig. 1 there is cally, the path of a few of the projected and 32 are focused to project scattered, definitely shaped, or partially aberrated reflected images in the form of round spots, simulating a toy balloon, on the-surrounding surfaces. of the room in which theapparatus is-installed, as, for example, the side Walls R, L, the front wall W, the floor F, and the ceilingC, and' next setting the motor in motion to revolve the chandelier, thus giving motion to the said reflected images, due to the movement ofthe mirrors. r V
illustrated, diagrammatireflected images fromthe lanterns. The rays of light 40, 41 and 42 from the lantern 11 impingeon the mirrors 14 on the end portion.
' 109, and the mirrors 14 and 14? on the canopy portion 10 of the chandelier respectively,
and are reflected bysaid mirrors to show round spots40 41 3 42 respectively, on the front wall W, side wall L, and ceiling C re spectively; Likewise, the rays of light 43 and 44 from the lantern 12 impinge on the 'mirrors 14 and 14 to show as spots 43 and 44? respectively oncthe front wall WV and side wall R, respectively.
' Thereflected images are preferably given a I variety of harmoniouscolors by interposing aisuit able color screen in the pathof the projected light rays (not shown) or by providing aplurality of colored stripes of transparent material and 51 over each of the lenses to form multicolored images.
the light reflecting chandelier 100 is made in two port ons, theupper portion comprising chandelier in opposite directions. 1
From the above description and Fig.4, it is flector for simultaneously the canopy 100*, an integrally depending neck 100 and the lower portion forming the bulbous end 100. The upper portion is revolumove with the upper chandelier portion and the disc 123: with the lower portion thereof,
and the driving pulley122 being'adapted' to revolve the upper and lower portions of the apparentthat the-projected light rays 140 and 141 from the lantern 30', after being re-j flected from the mirrors 114 and 114 on the lower and upper chandelier portions, respectively, to form images 140 and 141 on the ceiling 0, moving in opposite directions when the upper and lower chandelier portionsare rotated by the motor. Similarly the projectpositely moving images 142 and 143 respectively on the side wall R.
It will thusbeseen that there is provided a device in which the several objects of this invention are achieved and which is well .ed light rays 142 and 143 will produce o-padapted to meet theconditions of practical use As variouspossible embodiments might be madeof theabove invention, and as various changes mightbe made in the embodiment above set forth, itis to be understood that all matter herein set forth or shown in the accompanying drawing is to be interpreted as illustrative and not in a limiting sense.
