June 18, 1968 R. ABRAMS 3,389,248
DWELL LIGHT Filed Oct. 23, 1965 INVENTOR. RALPH ABRAMS ATTOR (EY United States Patent 3,389,248 DWELL LIGHT Ralph Abrams, Warwick, R.I., assignor to Cable Electric Products, Inc., Providence, R.l., a corporation of Rhode Island Filed Oct. 23, 1965, Ser. No. 503,866 2 Claims. (Cl. 240-) ABSTRACT OF THE DISCLOSURE A dwell light in which the front wall of a molded plastic housing is provided with a plurality of multicolored lenses with reflector lamps behind them. A low voltage motor drives a contact arm slowly in a circle to successively contact arcuately spaced elements for lighting each lamp. By elongating the contact elements and the contact end of the moving arm, a dwell effect is created, each light remaining on for a predetermined period when the next succeeding light goes on.
My present invention relates to decorative lighting effects and more particularly to a novel construction of a dwell light.
The principal object of the present invention is to provide a novel decorative light construction which successively projects a plurality of colored lights.
A further object of the present invention is to provide a light construction utilizing a plurality of colored lights which can be used to light up a Christmas tree or similar decorative effects.
Another object of the present invention is to provide a dwell light construction having a minimum number of readily moldable parts.
Another object of the present invention is to provide a light construction utilizing low voltage and molded parts to produce a decorative dwell light effect at a minimum of cost.
A further object of the present invention is to provide a decorative dwell light with a novel circuitry for lighting a plurality of colored lights in succession with low voltage.
With the above and other objects and advantageous features in view, my invention consists of a novel arrangement of parts more fully disclosed in the detailed description following, in conjunction with the accompanying drawings and more particularly defined in the appended claims.
In the drawings,
FIG. 1 is a perspective view of a dwell light embodying my present invention.
FIG. 2 is a rear view of the same with the back wall partially broken away.
FIG. 3 is a diagrammatic view of the electrical circuit involved.
It is customary to provide colored spotlights and clusters of colored lights for decorative effect such as lighting a Christmas tree or even objects in a store window display. In commercial displays, many devices have been used to turn the lights on and off in successive order to provide a plurality of color effects. The present invention is designed to provide a simple and economically manufactured unit which can be used in the home for producing a decorative effect. The present invention utilizes a cluster of different colored lights with a dwell effect. This ensures that more than one light will go in on a given time and the lights go on successively to produce a pleasing visual effect.
Referring more in detail to the drawings illustrating my invention I provide a rectangular housing 10 having an open front, sides 11 and the rear Wall 12 preferably of integral molded plastic construction. The housing 10 will "ice be provided with a pivoted bracket 13 which may have an integral spike portion 14 for anchoring in the ground in outdoor displays. I now provide a front wall 15 also molded of plastic material and having integrally molded therewith a plurality of conically shaped light socket and reflector portions 16. In the illustrated form four light sections are illustrated. At the front, see FIG. 1, each section is covered by a plastic lens 1'7 each of a different color. For example, for purposes of illustration, the lens 17 may be red, the lens 18 may be green, the lens 19 may be blue, and the lens 2t may be yellow.
Mounted to the rear of the socket portions 16, see FIG. 2, is a rectangular plate 21. Mounted behind the plate 21 and spaced from it is a printed circuit board 22 having a central annular conductive disc portion 23 and spaced therefrom in annular form, a plurality of segmental strips each covering a quadrant and separated from the adjacent strip by an intervening space 26. As can be seen in FIG. 3, the central disc 23 is surrounded by segments 25, 27, 28 and 29, separated by spaces 26. The above described circuit connections, illustrated in FIG. 3, are mounted on board 22 as shown in FIG. 2 and face in the opposite direction towards the front of the housing. A small 12 v. electric motor, not shown, is mounted towards the front behind the front 15 and between the reflector portions 16. The motor operates at approximately 400 rpm. and by a succession of gears 24, drives a conductive arm 39 at approximately 4 rpm. The arm 30 is electrically in contact with the central disc 23 and extends across to an arcuate shoe portion 31 which wipes the segments 25, 27, 28 and 29 successively.
Now viewing FIGS. 2 and 3, each light is provided with a line 32 connecting it to one of the segments. The second cord 33 connects to each light. One end of cord 33 connects at 34 to one pole of a phone jack connection 35 mounted in the rear wall 12. This connection is also provided with a line 36 leading to one of the motor leads. The other side of the phone jack 35 is connected by a line 37 to the plate 23 and by a connecting line to the other motor lead. Power is supplied by providing a small class two transformer 38 having an on and off switch 39 for controlling the primary current passing through a standard cable 49 and contact plug 41 for connecting to v. house current. Since the transformer 38 reduces the current to 12 v. a light line 42 may be used having a phone jack for insertion into the phone jack connection 35.
With the illustrated and above described hookup, when the current is turned on the motor starts the rotation of the wiper arm 30. In the position shown in FIG. 3, the current will pass from the disc 23 in the center through the wiper arm 30 the wiping shoe 31 at the outer end into the segment 27 and from the segment 27 through a line 32 through the lamp into the line 33 and out the other side to lines 34 and phone jack 35. This will light the lamp in the upper right hand corner in FIG. 3 connected to the segment 27. When the shoe 31 reaches the segment 28, it will similarly light the light in the bottom right hand corner and so on around the circle. Whenever the shoe 31 straddles the gap 26 the lights connected to each segment will go on. The length of the shoe 31 is equal approximately to one half of one of the segments 25, 27, 28 and 29. If the drive of the arm 30 is approximately four revolutions per minute, it will make one revolution in approximately fifteen or sixteen seconds, so that it will take the shoe to ride across each segment, four seconds. However, since the shoe is one half of a segment, when it reaches the next segment it will still take two seconds to pass over the previous one. With this arrangement each light will be on for six seconds, for the first two seconds in conjunction with the previous light for the next two seconds all alone for the last two seconds in conjunction with the next light which goes on. There- 3 fore, successively each light goes on first with the previous light, after the previous light goes out the next light goes on and the light stays on for an additional two seconds. Therefore each light Will dwell While the next light goes on so that the combination is called a dwell light.
By utilizing a simple printed circuit connection, small motor and transformer and mated parts, the light can be manufactured at a minimum of cost and assembled with a minimum of labor. Other advantages of the present invention will be readily apparent to a person skilled in the art.
