Application March 4, 1941, Serial No. 381,628V

11 Claims.

This invention relates to display devices in general, and particularly to fireplace displays, intended to create the impression of live re emanating from imitation fuel, such as artificial wood logs, coal, etc.

One'of the objects of the present invention is to provide an extremely simple and inexpensive device of this kind, wherein easily constructed light-controlling means are employed, which are designed to direct light rays against a steeply inclined, translucent screen upon which the images of long, ever-changing, colored flame, sparks, smoke or clouds are impressed, and wherein such images of varicolored flames are caused to produce the effect of moving from without towards the center and also in upward direction, to create a realistic imitation of actual fire, with smoke and occasionally sparks, drawing up the chimney.

Another object of this invention is to provide in my device light intensity control means, whereby direct light, as well as major portions of reflected light, and images created thereby, are caused to become alternately and gradually visible and obscured, while the images projected upon a screen continuously change in colors.

Another object of the present invention is to provide in connection with a light source employed in my device, regulating means for controlling the speed of the mechanism actuating the light controlling devices.

The foregoing and still further objects and important advantages of the present invention will become more fully apparent from the ensuing description and the .accompanying drawing, which latter, although showing a specific construction of my invention, is by no means intended to restrict the same to the actual disclosure, and wherein:

Fig. 1 is a front elevation of my device;

Fig. 2 is a vertical cross sectional view through the device shown in Fig. 1, including imitation wood logs placed in front thereof;

Fig. 3 is a horizontal cross section through my device taken on line l3 3 of Fig. 2;

Fig. 4 is a top View of the light source and motive arrangement of my device;

Fig. 5 is a side elevation thereof partially in section; and A Fig. 6 is a top view of my device in its collapsed position, ready for shipment.

Referring now specifically to the figures, numeral IU denotes the back wall of my device, from which extend upwardly-broadening side walls I I. The latter are joined with the back wall by a top glass or a lm material, such as a sheet of Cellu- A loid, which screen is sharply inclined for reasons hereinafter explained. Below the screen is provided an opening, and in this opening is secured to back member I0 a hinged platform I3, which may be pivoted about point I1 so that the front portion of the platform can be swung down, as indicated in broken lines in Fig. 2. Supporting the movable platform portion is an upright I8, which is hinged at I9 and may be collapsed lto a flat, downward position, indicated in broken lines in Fig. 1. Movably secured to the'inclined edges of side walls II are two adjustable wings 20, which latter, when the device is to be shipped, may be swung towards screen I5, as indicated in Fig. 6, so that the latter will not be damaged.

In front of the opening, and extending somewhat above the lower edge of panel I5, an arrangement of actual fuel or of a fuel imitation is placed, such as imitation wood logs 2l indicated in Fig. 2. Supported by hinged platform I6 are sockets 22 for the reception of electric bulbs 23, which are surrounded by xed, nontransparent cylinders 24. The latter are preferably secured to platform I6, as shown at 25, and are provided with bottom vent openings 26. The passage ofair through these vent openings may be regulated by a sliding sleeve 21, provided with a handle 28 for facilitating its operation. When the sleeve is lowered over openings 26 the draft created by the heat of bulb 23 may be cut down. When the sleeve clears openings 26, the f ull amount of air is allowed to pass up cylinder 24. It will be observed that bulbs 23 and their cylinders extend partially outwards from the compartment below screen I5.

Above each cylinder is mounted' a fan 29, which is preferably supported by a fixed bracket 30, secured at 3| to rear wall I0 of the device. The free end of the bracket is bent upwards and terminates into a sharply pointed prong 32, upon which rests the conically shaped center 33 of fan 29. Extending from and secured to this raised fan center is a thin wire rod 34, which is guided at its upper portion in an eye of bracket 35 (see Fig. 2), sov that both the fan and rod 34 may freely rotate, when heated air emanating from cylinder 24 causes the fan to operate.

Attached to and slightly extending from wire rod 34, which latter is preferably very light and resilient, is a number of spaced, brightly polished spangles 36, which are inclined somewhat towards bulbs 23, so that they alternately reflect light from the latter onto screen I as their position changes. These spangles are preferably supported by small coils of spring wire members 31, which frictionally engage rod 34, and are adjustable in respect thereto, so that the spangles may be moved to various heights upon rod 34.

Secured above bulbs 23 to rear wall I0 of the device is a mirror 38 (see Fig. 2). Above the mirror are placed two superimposed, inclined sheets or panels, indicated at 39 and 40, see Figs. 2 and 3. Upon the lower panel 39, which may be made of glass or any other suitable transparent material, such as a cellulose ilm, there are provided zigzag or criss-cross formations of translucent, narrow strips 4I of differently colored material, preferably including green, yellow, red, blue and orange colors. With panel 40 there are arranged opaque tongue-shaped configurations 42, between which are provided similar, lightpassing tongues 43. Panel 40 may be made either from transparent material, with opaque tongues 42 painted or otherwise applied thereto, or may be fabricated in the form of a stamping from solid material, such as sheet metal, with tongues 42 stamped out from t'he metal.

It will be observed that tongues 42 as well as strips 4I are so positioned that their configurations are directed from the ends of panels 39 and 4I) towards their centers, providing a substantially herring-bone resembling design. This arrangement is made for the purpose of providing an illusion of flames moving from Without towards the center of the display. Attention is called to the substantially midway position of rods 34, extending from the fans, in respect to screen I5 and panels 39 and 40.

Referring to Figs. 4 and 5, it will be observed that on top of fan 29 there is placed a thin and lightweight curved body 44, which is intended to alternately prevent and permit the passage of light; through the fan, as the latter and body 44 rotate above bulb 23. This curved body may be either a separate stamping, secured to the fan, or it may form a part of the fan body itself. Such construction being obvious, a special illustration thereof is omitted.

Operation It will be observed from Figs. 1 and 3 that curved'shapes 44 mounted on top of fans 29 are disposed in opposite positions to one another, and that also the fans are arranged to rotate in opposite directions.

As the air within dark cylinders 24 becomes heated, a draft is created through passages 25 of the cylinders in upward direction. Heated air escaping from the top ofthe cylinders causes fans 29, segments 44 and rods 34 to rotate towards one another. A substantial portion of the light escaping through the openings between the fan blades will strike imitation fuel arrangement 2 I, placed in front of the device. Another major portion of the light passing through the fans will be reflected by mirror 38, through panels 39 and 4t, against screen I5. The reflected light is forced to first pass through translucent colored strips 4I and then through open fields 43 of upper panel 45. The resulting light images appearing upon screen I5 will resemble animated flametongue formations. Since screen I5 is sharply inclined in respect to mirror 38, these flametongue images appear relatively long and will diminish in light intensity towards their top ends.

This, together with the fluctuating light intensities caused by rotating segments 44, provides an impression of the flame-tongues dissolving into smoke or clouds. The colored strips 4I of lower panel 39 vary the coloring of the tongues, and in addition there will appear on the screen at various heights and at various frequencies tiny spark-resembling flashes, produced by minor light portions released through the fan openings being reflected by moving spangles 36. Thus a very realistic illusion of live flames, moving inwards and upwards, and of smoke and sparks, will appear upon screen I5.

Obviously I prefer to employ two spaced light sources to produce the desired light effects upon the screen. However, very satisfactory flame imitations may be elfected with but one light source, if the latter is placed below the screen center, in which event a somewhat differently shaped segment for controlling the light intensities of the images is employed.

It will be observed that the mechanism of the device is extremely simple, and although being so simple, will create a very effective illusion of flames, smoke and sparks emanating from the imitation fuel placed in front of the device. While I have shown and described specific forms and structures employed in my device, it is quite obvious that changes and improvements may be incorporated therein, without departing from the broad scope of my invention, as expressed in the annexed claims.
